Loosing Database Connection When Device Power-off (native Oledb Code)
Jul 12, 2006
Hi,
I experienced this problems on both Windows Mobile 2003 SE and Windows Mobile 5.0.
Its native development (c++, oledb, atl and mfc).
It's quite simple to reproduce...
1. open a database
2. open a rowset on table A (whatever, valid of course and with both IOpenRowset and ICommandText), read datas and close rowset
3. power off
4. power on
5. try step 2 with another table (failed on openrowset with error 0x80004005) or try table A (sometimes working because of cached memory, sometims failed on Read Datas).
6. being stuck ;-)
Our work-around was, in case we loose our connection (identified by error 0x80004005 on openrowset), we close it and re-open database... ugly for sure, but working.
What I'm looking now is to use some kind of "detection method" like what people in .Net develoment are using "if ConnectionState.Open <> ...) for reopening my database only on demand...
Thanks in advance for any hints,
Fabien.

Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005. When I hit the Start Debugging Button every time until today the project would rebuild and deploy to my pocket PC allowing me to debug etc but now I get
The remote connection to the device has been lost.
Please verify the device conection and restart debugging.
I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.
Does anyone know how to resolve this problem?

howdy,
i have a sqlserver2005 ssis package which connects to a mysql webserver to upload data. i am connecting via mysql oledb connection and am able to test connect ok through the oledb connection manager. However in my ole db destination editor i get an 0x80040E21 error when trying to preview a table . The full error is :
Error at Data Flow Task [Destination - Query [70]]: An OLE DB error has occurred. Error code: 0x80040E21.
Error at Data Flow Task [Destination - Query [70]]: Opening a rowset for "INFORMATION_SCHEMA.address_book" failed. Check that the object exists in the database.
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC02020E8 (Microsoft.SqlServer.DTSPipelineWrap)
I can see all the tables in the drop down box in connection manager. This has been driving me nuts for the last 3 days! I have tried changing some of the security connection settings to no avail, (although i am not sure on what these do).I have also tried setting up as an odbc connection using script components but had memory errors after copying several hundred records and the package just hangs. I can go into this in more detail however i dont think they are related issues and i would prefer oledb as i dont have to script my data transfer.
any help much much appreciated.
thanks

Hi List
Im trying to set up an implementation of Project Real --it works like this-
Create two system environment variables called REAL_Root_Dir and
REAL_Configuration with the values given below. Click on
Start -> Control Panel -> System. Go to the Advanced Panel, click Environment Variables button, then New in the System variables box.
If the Project REAL files were installed at C:Microsoft Project REAL, then the variable values will be:
Variable Name: REAL_Root_Dir
Variable Value: C:Microsoft Project REALETL
Variable Name: REAL_Configuration
Variable Value: %REAL_Root_Dir%REAL_Config.dtsconfig
The package OLEDB connections work like this
First read enviroment variable to get location of config file
Next read Config File to get connection string for Config Database
<?xml version="1.0"?>
<DTSConfiguration>
<Configuration ConfiguredType="Property" Path="Package.Connections[SQL - Configuration].Properties[ConnectionString]" ValueType="String">
<ConfiguredValue>Data Source=(local);Initial Catalog=DataWarehouseABC;Provider=SQLNCLI.1;Integrated Security=SSPI;</ConfiguredValue>
</Configuration>
</DTSConfiguration>
Next read Config database to get connection strings for Source and Destination databases
Destination database is called "DataWarehouseABC"
Source database is called "SnapshotABC"
the Source database OLEDB connection works 100%
however the destination OLDB connection we get this error below
PS--Both source and destination databases are on the same development machine , however both databases are restored bak files from another production machine
Error 1 Error loading LoadGroup_Daily.dtsx: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Login failed for user 'xxxxxx'.". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Cannot open database "DataWarehouseABC" requested by the login. The login failed.".
Any ideas on how one OLEDB Connection in this package can get this corruption
thanks in advance

Hi all,
We recently converted an application from accecc97 to access2003.
We used to have 2 databases : 1 with all and only the data (axelD.mbd), 1 with all the forms, query's, ... (axelP.mdb)
We replaced the data (axelD.mdb) with an MSDE database, through UPSIZE and so on. That all worked fine.
This database is placed on the dataserver (DATA1), the converted programm is on the FRONT2 server (FRONT1 stil usess access97 until conversion is totally ready).
We are able to connect to the MSDE by using ADODB recordsets.
We are also perfect able to link the MSDEtables in our axelP.mbd database
We started to test some heavier parts of our application and started to get the following error:
"ERROR 3151"
"ODBC--connection to 'JOROSOFT' failed"
Nothing more.
This happened in a quite complex routine, whitch updates a lot of records, several times and so on.
We could reproduce the same error when executing the following code:
Public Function TestBestellingen()
Dim sql As String
Dim intervalset As DAO.Recordset
Dim planset As DAO.Recordset
Dim tellerke
x = Opendatabases()
tellerke = 0
sql = "Select bestelnummer from vkpbestellijn where bestelnummer > 100000"
Set planset = Db_AxelP.OpenRecordset(sql, dbOpenDynaset)
Do While Not planset.EOF
tellerke = tellerke + 1
Debug.Print tellerke & " - " & planset!Bestelnummer & " --> " & IsKlantStof(planset!Bestelnummer)
planset.MoveNext
Loop
End Function
Function IsKlantStof(p_bestelnummer)
Dim sql As String, rst As DAO.Recordset
Dim hulp_klantstof As Boolean
hulp_klantstof = False
x = Opendatabases()
sql = "select klantstof from vkpbestellijn where bestelnummer = " & p_bestelnummer
Set rst = Db_AxelP.OpenRecordset(sql, dbOpenSnapshot)
With rst
Do While Not .EOF
If !KlantStof = True Then
hulp_klantstof = True
.MoveLast
End If
.MoveNext
Loop
End With
rst.Close
Set rst = Nothing
IsKlantStof = hulp_klantstof
End Function
Function Opendatabases()
If Db_AxelP Is Nothing Then
Set Db_AxelP = DBEngine(0)(0)
End If
End Function
I know this code makes no sence in a real-time environment, but it was to reproduce the error.
This code basically runs trough a 30.000 records and does a little check for certain fields
After 1981 records we get the above error.
(sometimes after 1979 or 1980 or 1982 records)
1977 - 100859 --> True
1978 - 100860 --> True
1979 - 100860 --> False
1980 - 100861 --> True
1981 - 100861 --> True
"vkpbestellijn" is a table that is linked in the AxelP.mdb trough an ODBC connection.
We get the same error (and after 1981 times) if I change the where to a totally other range of "bestelnummer"
I have installed the latest patches of Jet 4.0, MSDE-server, ...
I've been searching the internet for abour 3 days now, and just cant even find the smallest clue what could make this happen.
I hope someone here has an idea.
If you need more details, just ask.
tia,
Axel.
P.S. I'm from Belgium, so my english aint "correct to the point".

if (FAILED(hr))
{
return;
}
and also, afx oledb headers causing lots of redefinition warnings, if i include both ssce headers and afxole headers...
and also oledb example in ssce bol download is missing, there is no such like example...

Hi,
I'm getting a connection and then loosing my connection upon refreshing the browser with this script connecting to MSSQL using php, when trying the following:

I have a script and on one of the tables I keep loosing the mapping of the last 4 fields. If I go into the task it will ask me if I want it to automatically fix it and I say yes and remap fields but when I run it it bombs and comes back and when I go back into it it tells me there is a problem with same fields. It also rearanges the order and puts these fields last.
I have tried deleting and redoing the transformation only to have the same thing happen. Almost seems like a bug in software. I have seen this before but usually when I fix it it does not return.

For both OLEDB destiantions (and hopefully for the forthcoming ADO.NET destination adapter) it would be useful to have the following two output columns: NativeErrorCode and NativeErrorMessage.
For SQL Server, this would allow you distiguish between multiple errors which all roll up to the SSIS error "the value violated the integrity constraints of the column", which is way too generic for proper decision making (via conditional split).
For example, like SQL Server replication, you should be able to ignore duplicate key errors (error number 2627) indicating the record existed, but error out on nullability constraint errors (number 515) in which the record could not be inserted. If you had a native error code, you could make this decision, while the SSIS error for two different native errors is precisely the same.
There is a known and accepted race condition between a lookup transform and subsequent OLEDB dest insert attempt (assuming a non-transacted container and a common component target table), which is why the 2627 can be safely ignored in certain instances, while a 515 should not be.

I am trying to dynamically change my initial catalog in a SSIS project. Each day I get a snapshot of data from the production server. I am performing ETL on that database and loading it into my warehouse. I am trying to put something together so that each day I get the latest snapshot and if its newer then my most recent one I pass that new catalog into the connection manager. I can already run the sql script to compare the two catalogs but I can't populate the connection manager.

Hi,
What is the best way to have native win32 code tell SQL Server 2005 Express to synchronize for merge replication? What API should I use? Should I exec the distrib.exe and/or replmerg.exe command line utilities? Should I use "Windows Synchronization Manager"? Are they other options?
Thanks,

I apologize if this is not the correct forum for this posting. Looking at the descriptions, it appeared to be the best choice.
I am running Windows XP Pro SP2. I have installed the SQL Native Client for
XP. However, when I try to add a new data source through ODBC Connection
Manager, SQL Native Client is not listed as an option. I have followed this procedure on three other systems with no problems. What would be causing the
SQL Native Client to not show up in the list of available ODBC data sources?

This happens only sometimes. If I recreate the command object and executing it again (with the same connection object) no error occurs.
Except for this case the application works fine.

Hello, everyone.
I have to make a gateway to access third-party closed-source native-code COM objects. As an interface, SQL Server stored procedures are absolutely perfect for my needs. I decided to use SQL Server 2005 CLR rather than using deprecated extended stored procedures or accessing COM objects directly through SQL Server. (This decision is aided by the fact that the third party has plans to make a .NET version of their COM objects "really soon now" (i.e.: not soon enough). Backporting their new interface to my abstraction layer will be very simple.)
I'm having problems using these COM objects from my SQL Server 2005 CLR stored procedure. When I try to run my stored procedure, I get the error below. It appears that SQL Server/CLR refuses to perform the disk access necessary to load the COM object from disk so that it can instantiate it. (My message continues after the error.)
Msg 6522, Level 16, State 1, Procedure MyStoredProcedure, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProcedure':
System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.
System.IO.FileLoadException:
at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection)
at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection)
at System.Reflection.Assembly.InternalLoadFrom(String assemblyFile, Evidence securityEvidence, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm, Boolean forIntrospection, StackCrawlMark& stackMark)

at System.Activator.CreateComInstanceFrom(String assemblyName, String typeName, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm)
at System.Activator.CreateComInstanceFrom(String assemblyName, String typeName)
at UserDefinedFunctions.MyStoredProcedure()
.
I'll outline the steps I performed so far to get the assembly working:
Ensured I was running at SQL Server 2005 compatibility level. (90)
- Installed and configured the third-party COM objects on my devel box and my DB box. They registered themselves properly.
- Enabled CLR in the DB.
- Made sure the DB owner has UNSAFE ASSEMBLY permission.
- Added the TRUSTWORTHY property to the DB. (Yes, this isn't the "correct" way to do it, but I didn't want to deal with code-signing voodoo. Apologies to actual believers in voodoo.)
- Created an Unsafe assembly "MyAssembly" in SQL Server 2005 and Visual Studio 2005.
- Created all the necessary Interop assemblies (by creating a normal (non-SQL) C# project and building my code, and raiding the bin directory).
- Added these Interop assemblies to SQL Server 2005 as Unsafe assemblies.
- In VS2005, built my SQL Project code and deployed successfully.
- Tried running my stored procedure through a Query window, and I got the error above.
I've done many searches. All of the results I've found concern themselves with Web Services and XML serialization, and suggest using sgen.exe. I don't think they're relevant to my problem. A few said I should add my COM DLLs as assemblies to SQL Server, but that is impossible for native code DLLs. I found something that hinted at tblexp.exe, but I didn't understand how that could help me. I already figured out a way to get me the Interop libs.
Efforts at solving:
- Reading webpages for hours on end.
- I tried using sgen.exe to create the XML serialization assembly, but it didn't help.
- I tried adding various native-code DLLs directly as SQL Server assemblies, but you can bet it didn't like that.
- A few other pitiful attempts not worth mentioning.
- Reading this forum. I didn't see anything that applied.
- Posting here.
I really wish Microsoft had meant what they said when they stated that "Unsafe" assemblies can access anything, instead of trying to protect developers from their folly.
Any insights on getting those COM objects to work in my CLR stored procedure? Thank you.

I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.

Howdy folks! (I feel im creating too many topics...but all my questions are unrelated :-/)
Dev environment: SSCE, Native c++ OLE code, Win CE 5
I have a routine that calculates the size of a set of columns in order to create a byte buffer for retrieving data from an IRowset and inserting it into a custom class. This method works great for all data types except ntext. When I look at the column information from an ntext field, the DBCOLUMNINFO::ulColumnSize member holds 536,870,911 (the max length of an ntext type). Obviously I dont want to allocate 1GB of memory for each ntext column. Is there anyway (natively) to determine the actual number of characters in a field?

hi,
Can I write a dll(or share the same code) that works on both Mobile device and pc? Since we are using compact edition, we are hoping we can write some common module with the same code that could works on both mobile device and pc platform. I noticed the reference is the same, System.Data.SqlServerCe.dll 3.0.
Another question is, we already have a module for SQLCE2.0, with .net CF1.0. Now, we will start to use compact edition, should we just update on the 1.0 one, or we have to write a different one based on .net CF2.0? Can I use compact edition in CF1.0 dll?
Thanks.

I found a peculiar thing today while working with SQL Mobile in a multithreaded application (VS2005, application for Pocket PC 2003).
I created a class which has one SqlCeConnection object. Every time I call a function to insert/select/delete something from the local db, I open the connection, execute the query an then close the connection again.
But when I'm calling a function from the db class in thread 1 and in the meantime call a different function (from the same db class of course) in thread 2, things go wrong. Because when function 1 wants to close the connection, function 2 is still using the connection and it will crash my application with a native exception (0xC0000005: access violation).
I can see why the error is happening, but shouldn't there be a nice .NET handled exception instead of a native exception which grinds my app to a hold?
(A workaround I use now is to use multiple connection objects instead of one, but I thought I'd give this feedback anyway)

Hi,
I have two server instances of SQL on my server MYSRVR: default (SQL 2000) and named SQLX (SQL 2005).
I've been using these strings ok for the default (SQL 2000):
"Server=MYSRVR; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
"Server=192.168.1.128; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
and these for the named (SQL 2005)
"Server=MYSRVRSQLX; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
"Server=192.168.1.128SQLX; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
But then adding the SQL port 1433 works for the default:
"Server=MYSRVR,1433; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
"Server=192.168.1.128,1433; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
But this, for named (SQL 2005) actually connects to default. The SQL port is causing the name SQLX to be ignored.
"Server=MYSRVRSQLX,1433; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
"Server=192.168.1.128SQLX,1433; Database=mydb; Network=dbmssocn; Integrated Security=SSPI "
Anyone any ideas?

Hello,
I try to connect the SQL Server from the mobile device.
my connection string is:
string conn_str = "Server= 10.0.0.11;Database=theDB005;uid=bahadir;pwd=abcd;Trusted_Connection=false;";
when i try to open the connection I get SqlException,altough the 10.0.0.11 machine is reachable.. is not allowed to access a remote sql server with ip?
Thanks in advance.

This code...
string Path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
// Create the connection fConnection = new SqlCeConnection("Data Source ="" + Path + "\TreeNotes.sdf" ;Password ="abcd1234";");
fConnection.Open();
...works on my device, but on my computer it gives SqlCeException with message:
The database file cannot be found. Check the path to the database. [ File name = Program FilesTreeNotesTreeNotes.sdf ]
I've tried all sorts of things, but the computer just can't find the database. I've even tried putting a copy of the database into...
C:Program FilesTreeNotesTreeNotes.sdf...hoping that the computer will find it there.
What am I missing?
