Question

WinCE 5.0: SqlException on SqlConnection.Open()

Asked by: dbrckovi

Hello!

I'm maintaining a WinCE 5.0 application written in C# (CS 2005).
It is supposed to connect to SQL Server Express 2005 database.
It was working fine for year and a half, but now we had to reinstall the server so it got new network name.
Since our connection string was hardcoded, I had to change it and recompile the application.

After I did this, the application won't connect any more. It throws an exception with this message: "SqlException".

When I run the compiled exe from any normal PC it runs perfectly, but it won't connect when I copy it to WinCE 5.0 terminal.
I can ping the server from my terminal without problems.

Do you have any suggestion what I might try to fix this?

On the terminal we have the following CABs installed:
sql.wce4.armv4.CAB
sqlce.wce4.armv4.CAB
System_SR_ENU.CAB

It is simply placed in /System/Startup folder so it is installed every time the terminal is turned on.

Thank you

try
{
	string connectionString = "Data Source=SERVERNAME\\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=False;UID=user;Password=password";
	System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection(Data.connectionString);
	conn.Open();
}
catch (Exception ex)
{
	MessageBox.Show(ex.Message);
}

I don't see the SqlException text.

 

by: dbrckoviPosted on 2009-01-14 at 11:21:48ID: 23376394

I'm sorry for late response. I was on a business trip for a few days an was unable to login to Experts-exchange. (Their firewall is blocking cookies)
 
>> I don't see the SqlException text.

That's was my problem too. This is all I was getting "SqlException", with no additional description.
However, after a few days of debugging I found that it works if I drop all tables in the database, and re-create them again.
I still have no idea what was the cause of the problem, but at least now it works.
