SQLCE, .Net 3.5 And Me Going Crazy Looking For A Lighweight Solution With Lightweight Prereqs
Feb 19, 2008
I take it SSCE 3.5 only runs under .Net 3.5? My project was updated from VS05 to VS08 but the target is still .Net 2.0 would this be why I cant use the SQLCE namespace.
Forgive me for being noobalishous but I have been thinking that SSCE 3.5 would be a great solution for my app as I want to be able to use SQL Server Express 2005 and some other Local DB system (SSE is too bulky for my app when networking is not required). But if the prereq is that the client must have .Net 3.5 installed then I am back to square 1 because .Net 3.5 is like 195Mb install (which i tried installing as a prereq on my friend's Vista Ultimate(?) machine yesterday and it crashed it). Aaargh!! How are you supposed to develop small DB apps (3.5Mb max for app footprint) in the VS environment that don't require massive installation prereqs???
Dont get me wrong I love VS but surely there has to be a way to minimise prereq overheads.

I create data collection applications on Mobile Devices for field biologists. The biolgists need to sync thier field data with a local database upon returning from the field. I am planning on using sqlce as my mobile database and am trying to get a grasp of what my synchronization options are. Here are some of my questions.
1.) Is there any way to synchronize data between a SQLCE database on the mobile device and a SQLCE database on the desktop (third party or othewise)? It appears to me that the answer is no, which is a shame. Whats the use of having a free light weight database that you can use on a mobile device and as a backend on a desktop but not sync data between them?
2.) If my hunch is right, what are my sync options? Installing SQL Server on every field computer is not an option ($$$). If I'm bound to using SQL Server as the backend database, is it possible to have a single SQL Server database on a webserver that the field locations could sync to remotely?
Any feedback to get me started in the right direction would be greatly appreciated.

Hi All,
Im trying to migrate a N tiered solution written in Java and Berkeley DB(in memory DB product) to MS stack. ie the in memory DB is being used as a middle tier caching solution.
Im considering using SQLCE where Berkely DB was being used, im guessing that SQLCE being an inproc DB may be faster than using SQLExpress etc.
Has any one tried to do this before? and if so can you share your experience?
Alternatively if you can provide any resources on the web that discuss SQLCE performance(ie not when run on WinCE etc)/ comparison of query performance between SQLCE and SQL Express/Standard that would be great.
Thanks in advance

I tried to use xml_prepare_document stored procedure when lightweight pooling is enabled. It does not work.
I tried to use sp_configure 'lightweight pooling', 0 and reconfigure.... It doesnt work.
Is there a way to disable lightweight pooling without restarting mssqlserver?
Thanks

I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?

Hello. I have a 32-bit SQL 2005 (SP1) server that is my current Production server. I also have a 64-bit SQL 2005 (SP1) server that will become my Production server. I have several SSIS packages that load/refresh data on a nightly basis to a few of my databases from DB2 (MVS). I have the packages setup on the current Production server (32-bit) and all is working well through the Microsoft OLE DB provider for DB2. However, on the 64-bit server, I am experiencing some issues with the SSIS packages failing due to large loads. Loads that are loading tables with 500K, or less, data seem to run without issue (through SQL Agent Jobs). But, larger table loads are failing.
I do have a linked server set up on the 64-bit server to the 32-bit server, for other processes. And because of this I have lightweight pooling turned off on the 64-bit server (because of distributed querying). Lightweight pooling is turned on on the 32-bit server. Could this be what is causing some of my issue? Since I don't have the lightweight pooling option turned on (on the 64-bit server), am I not getting the proper amount of through-put for my 8 dual core CPU server?
Thanks

Does anyone have any instructions on how to go about uprading a .sdf file
from sqlce 2.0 to sqlce 3.0?
I found this on an msdn website
(link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but
as you can see its very lacking on detail. (I included the link and content
referring to upgrading the database files so you won't have to go to the link
to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.
Upgrading Database Files
You can upgrade a database created with an earlier version of SQL Server CE
2.0 to a database created with SQL Server Mobile by using the SQL Server
Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on
a smart device.
When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server
Mobile database is created on the smart device. The new database, with the
file name extension .sdf, contains all the data that was in the source
database. You need to reinitialize the upgraded database to continue using it
for replication.
Note: If you are using replication or remote data access (RDA) as a
connectivity solution before upgrading to SQL Server Mobile, you must
synchronize the source SQL Server CE database (subscription database) with
the SQL Server database (Publisher). The reason for synchronizing before
upgrading to SQL Server Mobile is to ensure that any changes that exist in
the tables on the SQL Server CE database are updated on the SQL Server
database, because after the upgrade you must resubscribe or repull using the
new database.

VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION!
-----------------------------------
The following article is bogus and confusing:
How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy'
http://msdn2.microsoft.com/en-us/library/ms246989.aspx
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
Do not copy
The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file yourself.
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
-----------------------------------
The above article is bogus and confusing.
This is rediculous!
This is the most vague and convoluted bunch of nonsince I've ever come accross!
Getting caught out on this issue for the 10th time!
And not being able to find an exact step-by-step solution.
--------------------------
I've tried it and it doesn't work for me.
Please don't try what the article eludes to as I'm still sorting out exactly what is supposed to be happening.
If you have a step-by-step procedure that can be reproduced this properly please PM me.
I would like to test its validity then update this exact post as a solution rather than just another dicussion thread.
Many thanks.
This is the exact procedure I have come up with:
NOTE 1: DO NOT allow VB.net to copy the database into its folders/directorys.
NOTE 2: DO NOT hand copy the database to a folder/directory in your project.
Yes, I know its hard not to do it because you want your project nice and tidy.
I just simply could NOT get it to work.
You should NOT have myData.mdf listed in the Solution Explorer. Ever.
Create a folder for your data following NOTE 2.
Copy your data to that folder. * mine was C:mydatamyData.mdf
Create a NEW project.
Remove any Data Connections. ( no matter what)
Save it.
Data | View Data Sources
Add New Data Source
select NEW CONNECTION ( No Matter what, do it!
Select the database. * again mine was C:mydatamyData.mdf
Answer NO to the question:
Would you like to copy the file to your project and modify the connection?
- NO ( no matter what - ANSWER NO ! - Absolutely NO )
Then select the tables you want in the DataSet.
and Finish.
To Test ----------
From the Solution Explorer | click the table name drop down arrow | select details
Now Drag the table name onto the form.
The form is then populated with a Navigation control
and matching Labels with corresponding Textboxes for each field in the table.
Save it.
1) Run the app.
Add one database record to the database by pressing the Add(+) icon
Just add some quick junk data that you don't mind getting lost if it doesn't save.
YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Now exit the application.
2) Run the app again.
And verify there is one record already there.
Now add a second database record to the database by pressing the Add (+) icon.
NOW add some quick junk data that you WILL intentionally loose.
*** DO NOT *** press the save icon.
Just Exit the app.
3) Again, Run the app.
Verify that the first record is still there.
Verify that the Second record is NOT there.
Its NOT there because you didn't save the data before exiting the app.
Proving that YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Also proving you must add your own code to catch the changes
and ask the user to save the data before exitiing or moving to another record.
As a side note, since vb.net uses detached datasets,
(a copy/snapshot of the dataset in memory and NOT directly linked to the database)
the dataset will reflect all changes made when moving around the detached datasets.
YOU MUT REMEMBER TO SUBMIT YOUR CHANGES TO THE DATABASE TO SAVE THEM.
Otherwise, they will simply be discarded without notice.
Whewh!
I hope this saves me some time the next time I want to start a new database project.
Oh, and uh, for anyone else reading this post.
Thanks,

Hey all,I need to import an excel file into a SQL table. Users are able to modify and save the excel file. I have a stored procedure that calls a structured storage file which does the import. Both the excel file and the structured storage file reside in the same location. The first time that the stored procedure fires the DTS it works fine, but if the data in the excel file is overwirtten by a user it appears that the import does not function.Am I missing something here?Here is the SPROC:CREATE PROCEDURE [dbo].[importEmployees] AS
DECLARE @object intDECLARE @hr int
--create a package objectEXEC @hr = sp_OACreate 'DTS.Package', @object OUTPUTif @hr <> 0BEGIN print 'error create DTS.Package' RETURNEND
EXEC @hr = sp_OAMethod @object, 'LoadFromStorageFile', NULL, 'C:importEmployees.dts', ''IF @hr <> 0BEGIN print 'error LoadFromStorageFile' RETURNEND
EXEC @hr = sp_OAMethod @object, 'Execute'IF @hr <> 0BEGIN print 'Execute failed' RETURNEND

Hiya!
I have a VB6 app using ADO to connect to SQL Server 7. On one form I am doing two consecutive inserts and I want them to be wrapped in a transaction for integrity. My code looks like this:
connection.errors.clear
connection.begintrans
connection.execute statement 1
connection.execut statement 2
if connection.errors.count > 0 then connection.rollbacktrans else: connection.committrans.
On the BeginTrans line I get the following error:
-2147168227
"Transaction cannot start because more than one ODBC connection is in use". My NativeError is 0, I searched BOL and couldn't find anything informative so I think this is an ADO error only. Also, running sp_who in SQL showed everything was OK. So what's causing this error?
Thanks,
Sarah

Hi! Have you ever wanted to make life easier? Well, so I am :-)
I have to understand old database ported to ms sql server 2000. Well, the problem is that there are no primary keys at all, no constraints. Database logic is thrown onto triggers and Delphi applications. All fields that should be primary key are in people heads...just mentally :(
Well, you'll say try to find equal fields in different databases... well i was trying to do this. It's impossible...
Any ideas except social engineering?
Thanx

Let me please start off by saying if your response to this question is:
"That's retarded! Why are you doing it that way! Do it this way!"
Please refrain from answering my query. With that out of the way, here I go.
I have attached a Sql Server 7.0 db (.mdf and .ldf file) to an instance of MSSQL 2000. When this attach happens, MSSQL2000 automatically upgrades it.
I then detach the db, and place the modified files back into the directory the Server 7.0 instance looks for. Obviously the format of the db files (.mdf and .ldf) have changed following the upgrade. I need to know if there is anything I can do (script or programmatically) to modify the files so that my Sql Server 7.0 instance can read them properly when the engine goes online.
Thank you in advance for any tidbits you can provide

I keep getting this stupid error, if
any of you have time to kill and could look at this I would really appreciate
it.
This checks for a login in the
database and if it already exists it makes it unique.
In the error message, €˜ssewell504€™
was the value returned after the proc ran, the last 3 digits will be different
each time it€™s ran.
Thanks guys and take
care!Here's the error:
"Syntax error converting the varchar value 'ssewell504' to a column of datatype int"

Hello,I have two tables, Articles and Comments, with the following columns:Articles - [ArticleId] (PK), [ArticleTitle], [ArticleText], [ArticlePubDate]Comments - [CommentId] (PK), [ArticleId] (FK), [CommentTitle], [CommentText]I need to display on a web page the articles published during the last week and their comments.What I need is:1. Get Articles (DONE) 2. Get Comments for each ArticleThe solution I see are:1. Create a Stored procedure that somehow outputs 2 tables: Articles and Comments associated with those articles2. Create 2 Stored procedures: The first one outputs the articles. The second output all comments given an article ID In this case, while the data is being displayed on the page it will load the comments for each article. The problem is that I will have many round trips to the server.I know how to use (2) but this would give me many round trips to the database.Could someone help me out with this?Thanks,Miguel

I posted this scenario earlier and ndinakar said my code worked on (I guess) his own machine but has not worked on mine! Does that not sound funny? I need to ge through with this simple but frustrating stuff in time. I've implemented more complex snippets before this but I just can't figure the problem out.
Can anyone out there tell me what I could be doing wrongly? I wrote a simple stored procedure called 'proc_insert_webuser' in a database that has been moved to a remote server called LAGOS-NTS3. I executed it from SQL Query Analyser and it worked. When, however, I executed the same stored procedure from ASP.Net it gives an impression that a new record has been inserted and even displays the newly generated ID column to me. On checking the base table I found only blank columns with only the ID column having the generated IDs!
I'm perplexed. I checked the code and can't possibly spot the error. Can anyone help. Found below are snippets used.
CREATE PROCEDURE proc_insert_webuser
(
@applicantidnumeric(18) output,
@firstnamevarchar(18),
@midname varchar(18),
@lastname varchar(50),
@secretcodevarchar(18),
@my_errnumeric(18) output
)
AS
IF (SELECT COUNT(ApplicantID) FROM tbl_webuser WHERE Firstname = @firstname AND Midname = @midname AND Lastname = @lastname) = 0
BEGIN
begin transaction
INSERT INTO tbl_webuser (Firstname, Midname, Lastname, SecretCode)
VALUES (@Firstname, @Midname, @Lastname, @SecretCode)
commit transaction
SET @applicantid = @@IDENTITY
END
ELSE
BEGIN
RAISERROR('Error! Execution aborted. A matching user profile exist.', 16, 1)
SELECT @my_err = @@ERROR
END
RETURN
Then the ASP.Net stuff:
Sub PostData()
'connection string production
Dim cstring As String = "User ID = sa; Password = ; database = E-Recruitment; Server = LAGOS-NTS3; Connect Timeout = 60"
'connection instantiation
Dim cnx As SqlConnection = New SqlConnection(cstring)
Try
'open connection
cnx.Open()
'instantiates and execute a command object
Dim cmd As SqlCommand = New SqlCommand
With cmd
.Connection = cnx
.CommandText = "proc_insert_webuser"
.CommandType = CommandType.StoredProcedure
Dim param1 As New SqlClient.SqlParameter("@applicantid", 0)
param1.DbType = DbType.Single
param1.Direction = ParameterDirection.Output
.Parameters.Add(param1)
Dim param2 As New SqlClient.SqlParameter("@firstname", txtFirstNM.Text)
param2.DbType = DbType.String
param2.Direction = ParameterDirection.Input
.Parameters.Add(param2)
Dim param3 As New SqlClient.SqlParameter("@midname", txtMidNM.Text)
param3.DbType = DbType.String
param3.Direction = ParameterDirection.Input
.Parameters.Add(param3)
Dim param4 As New SqlClient.SqlParameter("@lastname", txtLastNM.Text)

Dim param5 As New SqlClient.SqlParameter("@secretcode", txtPWD.Text)
param5.DbType = DbType.String
param5.Direction = ParameterDirection.Input
.Parameters.Add(param5)
Dim param6 As New SqlClient.SqlParameter("@my_err", 0)
param6.DbType = DbType.Single
param6.Direction = ParameterDirection.Output
.Parameters.Add(param6)
.ExecuteNonQuery()
'pick the auto-number
Dim strAppID = .Parameters("@applicantid").Value
'notifies the user of record success
lblMessage.Text = "Profile created. Your ApplicantID is : " & strAppID & " Kindly take note of your UserID. You'll need it for future logins."
End With
Catch ex As Exception
'notifies the user of any error(s)
lblMessage.Text = Err.Description & " originating from " & Err.Source
Finally
cnx.Close()
End Try
End Sub

Hi
I have and issue with a query, I tried every thing but I couldn't find why. Here is the issue, I have one big DB1 with about 30 tables, the query based on a join of 5 tables, I have the right index in place, when I run the query it will take about a minute and 20 sec. But I have another DB2 on the same server and I imported just the 5 tables form DB1 with the same index, when I run the same query it will take 6 seconds.
I did drop and recreate the indexes and drop and recreate the statistics but still the same thing no difference.
I'm running SQL7 SP3.
Do you have any idea what might be the issue here?
Thanks for your help

Hi all,
I am having a serious problem developing my reports within VS2005. For no reason, on one of my report it seems the parameters have got a life of there own.
There is a collection of 4 parameters whose values change randomly (internal, hidden, multivalue). Regardless of what I set them to, once I click save some change, when I alter 1 parameter, the values of one of the other parameters change while the settings for the parameter I changed to not apply.
What is going on here, I have been developing reports without issue however this is becoming a major concern. Please help!
Kind regards

Hi Guys, I have a syntax error in my SQL SELECT Query that is driving me crazy. All I am doing is adding a conditional with a literal value and that is breaking the query.This Query Works: SELECT
Quantity,
CAST(Gallons AS VARCHAR(10)) + ' ' + Style,
Colour
FROM
ORDER_TANK_LINK
LEFT JOIN TANKS
ON TANKS.TankID = ORDER_TANK_LINK.TankID
LEFT JOIN COLOURS
ON COLOURS.ColourID = ORDER_TANK_LINK.ColourID
This One is Broken:SELECT
Quantity,
CAST(Gallons AS VARCHAR(10)) + ' ' + Style,
Colour
FROM
ORDER_TANK_LINK
ON ORDER_TANK_LINK.OrderID = 1
LEFT JOIN TANKS
ON TANKS.TankID = ORDER_TANK_LINK.TankID
LEFT JOIN COLOURS
ON COLOURS.ColourID = ORDER_TANK_LINK.ColourID
Obviously I haven't explained the design of the tables, but because of the fact that I have another query that is so similar working perfectly, I didn't think you'd need it.
The exact error is "Incorrect Syntax Near the Keyword 'ON'". OrderID is definately a value of the ORDER_TANK_LINK Table and is of type int.
Thanks in advance!

I'm trying to do a basic update query which is working on other pages but not on this page. Dim uid As Integer = CInt(Session("uid"))
Dim cmd As New SqlCommand("UPDATE [cvdata] SET [jobCompanyName] = @inputJobCompanyName WHERE [user_id] = @uid", strConn)
With cmd.Parameters
cmd.Parameters.AddWithValue("@inputJobCompanyName", inputJobCompanyName.Text)
cmd.Parameters.AddWithValue("@uid", uid)
End With
cmd.Connection.Open()
cmd.ExecuteNonQuery()
cmd.Connection.Close()
The funny thing is that if i remove inputJobCompanyName.Text and add a custom value (for example "test") it works.So it doesn't seem to read my updated textfield or something im clueless.Kind regards,

First; thanks for looking.
On SQL Server 2000. IBM X series, dual 2GHz Xeon processors, 3GB RAM, RAID 5 DB array and separate Mirrored drive for OS, Windows 2000 Server.
Note: I should have moved the log files to the mirrored volume - I only just noticed it wasn't like that ... oops.:o It only has the OS and backup files (different logical volumes).
Problem: I have a Bill of Material system. It has a batch (Stored Procedure) that explodes Order Line Items. Each line has about 40 components.
The SP has 5 major steps to explode the Assembly, figure out colors/sizes to get the actual part numbers, assign quantities, update flags on the line item table (that has 3,500,000 rows but is not a clustered index - fill factor 85% on the unique autonumber index I use for the updates). The SP is jam packed with User Function calls, sub-Stored Procedures, and (yes) some cursors (on small declared temp tables created for each Order Line processed).
The execution plan for the whole batch of 100 is humongous - like 1000 pages, however nearly all steps are about 16 - 40 milliseconds to execute.
It normally takes 13 seconds to process 100 line items (3900 assembly rows created). However; about every 20th run, it takes 2 or 3 minutes ON THE VERY SAME LINE ITEMS. No programming changes! Run back-to-back, or with a minute or two delay. Then running it again, back to 13 seconds. Sometimes it takes 25 or so seconds, but that oddball 3 minutes is a killer.
I put some timing INSERTs into a temporary log file to localize the problem.
So; here's the REALLY weird thing. The part that experiences the intermittent 2 minute delay is a VERY SIMPLE call to a SP that INSERTs to the tbBATCHs table and gets the identity and passes it back with an Output variable. The tbBATCHs table only has about 8 columns. Nobody else uses it so it's not locking. It has an "If Exists" selection following the Insert to see if another batch is in progress not yet flagged as complete, but's not the issue because it's never true (hard coded values for testing forces this).
I have a Standby Server (duplicate config of main server) so I ran it there. Same issue.
If I loop 100 times on the tbBATCHs INSERT SP, it is pretty quick (like 2 seconds for all 100).
It's never on the first run, so I think it may be some sort of Log File catch-up.
Also; I DO NOT have Transaction Logging in place yet.
Ideas?

Basically the parts in red work best when they use the 'or' criteria.
My problem.
I run the query together black+red and get a different result than expected. Is there a way of saying 'do the black part first and its an imperative that the red part follows those rules on the black part of the query?' eg:
IDStatus must be LIKE '' when running the black part of the query
and expressemail must be like '%@%' on the black part of the query but not on red part of the query. So it doesnt matter that the expressemail must have idstatus like '' whilst having an @
Hope it makes sense??

Hi,
I have created a new user in my database called "acm", I also created a new schema called "acm" as well, the "acm" user is its owner, and the default schema for "acm" user is the "acm" schema.
I also created a login called "acm" (surprise surprise) and set its default database to "mydb" database.
In "mydb" database I have a table "mytable" that is owned by "acm". In my connection string I am using "acm" as the user, but when I do:
"select * from mytable" I get error ("bla bla object bla bla"), when I use "acm" as a prefix for the table name it works fine... What do I miss??
My connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAccountManagerDb.mdf";Persist Security Info=True;User ID=acm;Password=acm;Connect Timeout=30;User Instance=False
Thanx,
Yuval.

Hi everyone,
I am new to T-SQL and am trying to do some simple database for fun. Here is my problem and hope you guys can drop me some hint or solution:
OS: Win XP pro
SQL Server 2005 Express
Tool: SQLCMD in command prompt
I created a database and then create a table. Then I tried : select * from contract_Info, it gave me this:
1> CREATE TABLE Contract_Info
2> (
3> Order_No varchar(50) NOT NULL ,
4> Company varchar(255),
5> Product_Name varchar(255) NOT NULL,
6> Discount_Rate varchar(50), --Discount_Rate (%) -> Discount_Rate
7> Status varchar(50) NOT NULL,
8> Quantity varchar(50) NOT NULL,
9> Remainder varchar(50),
10> Deleted bit
11> )
12>
14>
15>
16> INSERT INTO Contract_Info values ('00000', 'DEFAULT','DEFAULT','0','Cancelle
d','0','0',0)
17>
18> go
(1 rows affected)
1> select * from contract_Info
2> go
Order_No Company
Product_Name
Discount_Rate Status
Quantity Rema

This one isn't so simple.I have a list of training modules, training complete dates and a list of employees in separate tables. I'll give an good example in a second. The problem I am having is that I need to generate a select statement that will generate a kind of 'spreadsheet' that will list the employees in the rows, and columns containing the results in the fields (the training module may or may not have been completed, and thus may or may not be in the result box. I think the example explains it fairly well (note, I did not design the database structure but have to work with it).Employees table:empNameJane DoeAlton BrownJohn DoeTrainingCourse table:courseNameWeldingBrain SurgeryScuba DivingResults table:empName: courseName: completeDate:Jane Doe Welding 2/2/2002Jane Doe Brain Surgery 3/7/2005Alton Brown Scuba Diving 9/23/2004Alton Brown Welding 11/4/2004John Doe Brain Surgery 6/14/2003End result of select statement: Welding Brain Surgery Scuba DivingJane Doe 2/2/2002 3/7/2005 Alton Brown 11/4/2004 9/23/2004John Doe 6/14/2003 Thanks a million to anyone with insight into this. I'm still trying to figure out a way to do this, but after a few days haven't come up with or found anything. Most things I've found online are too simplistic.

Is it just me, or are features missing in Management Studio? I mean, where is the "Export Objects" option when exporting data? Why is it so difficult to register a remote server? Why do the object views suck? And most important, why is the documentation the worst software documentation I have EVER SEEN?!
Things that were easy in Enterprise Manager with Client Network Utility and Query Analyzer seem impossible, difficult, or maybe just hidden in Management Studio. If it is there, the documentation sure doesnt tell you how to find it.
Please someone tell me that it's just me. Tell me that the features are there but Im not doing something right. I feel like putting my head in between my door opening and banging the door against it.

My app is working on my local system with the vs2008 development server. It's an asp.net app and I added the line:
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
So it works fine on my system. But I can't get it to work on shared hosting. I have uploaded all the sqlce 3.5 dlls to the bin directory. I am stuck at the error:
Access to the database file is not allowed. [ File name = ]
There actually is a file name in the connection string, and I set the permissions wide open on App_Data to test this.
What are the .net framework requirements for sqlce 3.5? I can't find this info anywhere.
I know sqlce 3.5 is not recommended for asp.net, but it is not the main site database but is used for a setup database utility to be installed for a windows app.

Hi,
We have over 1000 terminals running CE 4.2 on an x86 cpu currently using SQLCE 3.1.
We have just upgraded to VS 2008 and found the projects have been upgraded to reference SQL CE 3.5 - this is great, as we wish to use things like TOP etc.
However, all the distributable packages only include CAB files for CE 4.2 for the ARM Processor, or CE 5.0 for the x86. Is there a CAB package available for CE 4.2 for the x86 CPU? (please...)
Even just the relevant .DLL files would be fine as we repackage them ourselves anyway.
Thanks.
