Win CE 4.2 And Smart Dev Application Question
Apr 18, 2006
I'm a bit stuck with this one... hope someone can help.
I'm trying to develop an application that will run on a pocket PC with Windows CE 4.2
I'm using .Net 2003 and the application is in VB.Net.
I can run the application on the pocket pc fine (ie. form paints, buttons work) , until I need to connect to Sql DB on the server.
When I try to create a connection object (Dim dbconnection As New SqlClient.SqlConnection)
I get an error stating .. "This application (test.exe) requires a newer version of .Net Compact Framework than the one installed on the device" .... "could not load System.Data.SqlClient.SqlConnection from assembly System.Data.SqlClient Version=1.0.5000.0"
The version that it is looking for is. 1.0.5000.0 . The VS2003 is using this version.
I've downloaded the compact framework v1. sp3 , ran all the cabs on the Win CE device ... it looked that it installed fine.... but the problem still exists.
Help Please..

Hello All,
I've been trying to get a range of values out of my SQL Server 2000 db without sucess. The field in question has the data type of char(8) and looks like this:
House_numbr_pub (leading spaces in front of each value)
140A
140
141
142
143
144
145
146
147
148
149
150
151
.
.
.
14500
.
.
.
Does anyone know how write a sql statement that will return 140-150, but excluding the ' 14500' and 100-1000. I tried the following where clause to return a range between 100-1000.
WHERE (cook.STREET_PUB LIKE 'lincoln%') AND (LEN(LTRIM(cook.HOUSE_NUMBR_PUB)) BETWEEN 3 AND 4) AND (
(LTRIM(cook.HOUSE_NUMBR_PUB) >= '100') and (LTRIM(cook.HOUSE_NUMBR_PUB) <= '1000') )
This where clause only return two records (100 and 1000). I want it to return 100-1000.
I also tried the following where clause:
WHERE LTrim(cook.HOUSE_NUMBR_PUB) like '1[45][0-9]'
OR
LTrim(cook.HOUSE_NUMBR_PUB) like '1[45][0-9]'
However, building this on the fly with .net will take some effort if someone is trying to search range 1-10000000.
Please Help,
James

Is it possible to do the following without cursors or creating an identity column:
I have a table from legacy data with ~ 1 million records. I need to insert this into the new table which has a unique varchar(11) key. For the new system this key is generated by calling a SP that returns the next key in sequence. To put the legacy data records in the same table I want to first create a new column at end of legacy data table and populate this using SQL without going thru using cursor and calling the SP for each and every record to get a unique varchar(11) key.
In short here is what I want:
Field1 Field2 varchar(11)key
------ ------ -----------
jsdhf dsf99 1LEG
878jh whjhj 2LEG
8728jh whjhj 3LEG
8578jh whjhj 4LEG
3878jh whjhj 5LEG
6878jh whjhj 6LEG
8508jh whjhj 7LEG
...
...
...
4878jh whjhj 1000000LEG
How do I generate this key using an SQL stmt?
Thanks in advance,
Nishi

Hello forum.
I have a problem that is kill me.
Initial dates: a table (Tbl_1) to collect dates from users (within form in VB), a view (View_1) to compute some columns (is a part from business€™ logic) and a table (Tbl_2) designated for a trigger.
I will try to resume the contents of above table€¦
create table Tbl_1
(
id int not null,
code varchar(10) null,
TBO int not null, -- (Time between Overhauling)..hours (life cycle)
T_Hrs_AtLastOvh int null, -- total running hours from last overhauling
TRH int null, -- total running hours (the life of equipment)
)
GO
Create view View_1
as
select code, [TBO]-([TRH]-[T_Hrs_AtLastOvh])as HrsTo_NextOvh
from Tbl_1
GO
create table Tbl_2
(
id int not null,
code varchar(10) null,
Start_dt smalldatetime,
Stop_dt smalldatetime,
)
GO
--drop table Tbl_1
--drop view View_1
--drop table Tbl_2
Let to insert some dates into Tbl_1:
Insert into Tbl_1
select 1,'cod1',2000,2500,3000
union all
select 2,'cod2',3000,4000,7000
union all
select 3,'cod3',1000,2000,2000
union all
select 4,'cod4',1500,3000,3000
GO
The result of View_1 is in Fig.1:
Fig.1
cod1
1500
cod2
0
cod3
0
cod4
2500
cod1
1500
cod2
3000
cod3
0
cod4
2500
Fig.2
The operator perform requested job for the equipment and the life cycle starts counting again. Suppose to have:
Update Tbl_1 set T_Hrs_AtLastOvh=7000 where id=2
GO
The result of View_1 is Fig.2.
I wish to insert (within trigger) into table Tbl_2 all codes that have [HrsTo_NextOvh]=0 from View_1 and automatic to record the date when the record is done with a propertie like €™starting job€™.
After the operator executed the job, he will update the Tbl_1 (the result is in Fig.2) and the trigger has to record this process with the propertie like €˜completed job€™.
Depending by the time between overhauling and the operating hours of equipments, this task happens more or less often.
My intentions are to record the time requested to executed a job and to make a history of events.
Any suggestion to solve my problem is full apreciated.

I'm having problems implementing the following in reporting services 2005.
My hierarchy looks like this (just to illustrate the problem...):
University->Student->Exam
My query returns the following fields:
University,Student,StudentPayment,ExamName,ExamScore
I need to create a report that will show the hierarchy and to smartly aggregate the StudentPayment to both the Student and the University levels.
The problem is that the StudentPayment field is being multiplied by the number of exams in the upper level aggregation.
If only I could set the granularity level of the StudentPayment measurement...
Note that I don't have access to the query, so I can't change anything on that front.
Thanks,
Efi

I'm still a database newbie so I would like to solicit thoughts aboutthe smartest way to do something in sqlserver.My company has a web application that we customize for each client.We can do this because everything is database driven. We havedatabase tables that contain our HTML and database tables as well assome standard tables for each database. We have an in house app thatlets us tweak both of these things and creates a new web site anddatabase tailored to each project.Each of these sites has a table that stores a schedule are clientsuse.The records in this schedule table change when information in othercustom generated tables change.My company currently uses a legacy foxpro app to update the scheduletable.The foxpro app contacts sqlserver, reads a table with a list of tablesand scheduling information to check, checks each of those items andupdates the schedule table.I would like to lose the foxpro app.At first thought.........as a database newbie.......putting triggersin each of the tables to update the schedule when something changesseems the way to go.However, since we change a part of the schema ( we have an app thatgenerates the database tables unique to each client ) for each clientI would like a scheme that would not involve having to create adifferent trigger for each new table.I would also like something that updates in real time. Right now thefoxpro app is executed once a day.I was thinking of making a large stored procedure and putting anidentical call to that procedure in each table.Each table would have the same trigger in it that would get fired whenthe record was altered. It would call the stored procedure withrelevent arguments to update the schedule.Does this sound like a smart way to solve this problem or am I notthinking "database enough"?Any thoughts are welcome.I would like to build a better solutionSteve

Hey all... great site!
Here's what I'm going for:
I have an 05 VB.NET windows application that will be used as a smart client for our folks in the field. The windows application includes 05 SQL Server Express. I have included in the Data Sources of my project and attached file going through the wizard Microsoft SQL Server Database File (SqlClient) ='s (myfile.mdf) and then selected all tables, views, stored procedures, and functions... the corresponding myfileDataSet.xsd with the myfile.mdf are now located in the root of the project. I now recompile the project without error and go to the properties section Publish tab... select the Application Files button and myfile.mdf Publish Status is set to Include and the Download Group set to Requried. With this in place I right click on the myfile.mdf from the Soultion Explorer and under the properties section have set the build action to compile and use the copy always setting for the Copy to Output Directory.
My app.config looks like this:
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="myfile.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
</configSections>
<connectionStrings>
<add name="myfile.My.MySettings.ffgscrmConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|myfile.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
After the publish is completed on the client machine... install for Windows Installer 3.1, SQL Server Express, and the Windows Application contains no data but everything else works fine.
My problem is that I need to attach the myfile.mdf to the new SQL Server Express instance on the client machine during the installation process so that when the application fires it will be pointed to the above location on the client.
Any ideas... scripts... includes for an ApplicationEvents.vb on how to do this? Thanks a ton... :)
Kind regards,
BillB

declare @ContactId as integerset @ContactId = 5select *from Person.Contactwhere ContactId = @ContactIdOR @ContactId = -1If you run this in SQL 2005 on the AdventureWorks database,why the logical reads is 561Table 'Contact'. Scan count 1, logical reads 56and not 2 when you run without the second OR condition:declare @ContactId as integerset @ContactId = 5select *from Person.Contactwhere ContactId = @ContactIdHow can i use the same SP and either get one record returnedby passing the ID of the field, or pass a dummy parameter like-1 in order to get ALL the records returned.In this case even when i pass a parameter like ContactID = 5there is still a table scan (clustered index scan in this case)happening for the other OR condition.There's no method to tell SQL to start checking the first conditionwhether or not it is true then if it is false then check the second ORconditon. On the same topic does this mean all OR conditions areALWAYS verified regardless if one of them has already been determinedto be True?Thank you

Hello geniuses
First of all I would like to announce that this is my first time I post here.. However, I'm pretty sure that I'm in the best place to ask what I want. To cut the story short, I'm querying SQL database on a remote machine and having the result saved (mapped) to another table on another database on the same remote machine. The thing is the destination table was empty before the query was run the first time. I have been searching for some smart way so that when I modify the source tables that my query is based on, it doesn't affect except the modified rows. In other words, it should be like if the row is already there, do nothing. otherwise, it updates the existig record. else, it's a new record and it's inserted. I think what i need will include some coding for sure, yes? I don't know if i'm clear about the requirement or not though! but I know that you are experts and can direct me. Waiting for your valuable replies.

I've created a simple application that uses a SQLCE 3.5 database. When I debug it SQLCE 3.5 is deployed to the emulator. However, I made a "smart device cab project" for my application and copied the cab file to my windows mobile 6 device and it does not deploy SQLCE 3.5. I don't see a way to specify the prerequisites of the "smart device cab project" like you can in a normal setup project. How can I get SQLCE 3.5 to deploy with my application...or even just get it on my device? I've tried installing it on my desktop with the device connected via active sync, but it doesn't install on the device like the compact framework did.

So in a previous thread I discovered that in order to actually subscribe to any publication, the publisher needs to be a well-known network name, requiring DNS resolution. You can't simply point a SQLExpress instance at an ip addressinstance and have it resolve the communications.

Is there any other architecture proposed for Smart client arcjitecture where the data tranfer will be in a couple of GBs. Can somebody tell me more about SOA as well

What is the best way to compare two entries in a single table wherethe two fields are "almost" the same?For example, I would like to write a query that would compare thefirst two words in a "company" field. If they are the same, I wouldlike to output them.For example, "20th Century" and "20th Century Fox" in the companyfield would be the same.How do I do this? Do I need to use a cursor? Is it as simple as using"Like?"

Hi
I have created a Smart device application for Windows CE 5.0 device using Visual studio 2005 and i have added the smart cab project to the solution. When I add project out in teh appllication folder, the detected dependencies are not included. Instead dependent files appear with red circle in solution explorer.
My project uses .Net Framework 2.0 and SQL Server mobile 2005 and SQL Server mobile database file and some symbol files
I need included all of them in my cab project and when user clicks on it (in the device) it should install all of them.
Let me know why detected dependencies are not included in the Cab project and how can get all the above mentioned things to be installed along with my program

Hi
I have created a Visual Basic application the connects to my SQL database.
The appliction lets a user click on a button, data is retrieved from the database
and then formatted in Excel. Everything works fine on my machine (this is probably
because i have both VB and SQL installed on my machine)
I have created a .exe and deployed the application on some users desktops. The
problem is that when they click on a button - nothing happens. I dont even get any
error messages! Everything else appears to be fine. I have tested the DSNs and
they appear to be fine too.
Does anyone know why this would happen ??
Thanks, Ruaidhri.

Whenever a user logs on to SQL-Server there´s
a message in the application log of windows NT
like
"Login succeeded for user 'Domainusername'. Connection: Trusted."
Since we have lots of users. The application log fills up twice a day.
Is there any way to prevent SQL-Server from doing this ?
(I know that there are settings in the event-viewer which clear events
whenever space is needed).
Thanks.

I'm not sure if this is the right section for the question, but here goes...
I have an application that needs to be run in network client mode. This app is supposed to connect to a SQL 2005 db hosted on a server. As I procede through the installation process I get a prompt when i populate the serverdb information.
'The listener port was responsice, but did not return a primary port number for <servername>. Please verify that <servername> is a valid and running database before proceeding.
A little background is in order:
Host:
Server 2003 Standard
SQL Server 2005
Installed instance of said db
Client:
Windows XP Pro sp2
Network config:
We have a domain with about 125 workstationslaptops. Windows firewall is turned off using a group policy (makes it easier to push apps out to clients). For giggles I made exceptions to the 'turned off' firewall policies for the needed ports etc. This was done on both the host server and the client.
Thank you in advance.
