Hi,

we have moved Strataframe database to a new server, configured connections to a new location in all applications but since this moment we have problems when openning DDT, BOM and LME.

When we start any of those applications we receive the following error (after about 30 seconds waiting):

UIException
  Dynamically populating the ListView failed.  Could not create and fill the business object of type 'SFMessaging.MessageProjectsBO'
TargetInvocationException
  Exception has been thrown by the target of an invocation.
SqlException
  Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

Then on the second attempt it opens database correctly so we can work but it is very annoying to always wait 30 second for an error and then make a second attempt...

We have already tried to reinstall SF on the computer but no change. It seems to me that on the first attempt it tries somehow to open a connection to an old server.

Can anybody help me, please?

Thank You

George

Hi George.

First thing would be to check the Database Connection menu at the StrataFrame menu on Visual Studio.

You can also try deleting the connection files which will force you to rebuild them once you run Visual Studio again. These files are at C:\ProgramData\MicroFour\ConnectionData.

Hi Ivan,

thank You for Your response. I have deleted the file, configured connection but the behavior is the same - first attempt - error with delay, then it works correctly :-(

George

There is some problem on getting to your MessageProjects table. Can you open it alright using the SQL Server Management Studio and pointing to the new location? The exception is basically SQL Server telling you a timeout has occurred. Not sure why you get it working on a second attempt.

If you are using SQLExpress, then timeout needs to be manually set to 100. The default in SF is 60. I hit this issue and had to add the following command in SetDataSources of the Programs file:

   MicroFour.StrataFrame.Data.DataBasics.DataSources.Add(new SqlDataSourceItem(string.Empty, "server=xxxxxxxxx;user=xxxxxxx;password=xxxxxxx;database=xxxxxxxxx;Connect Timeout=100"));            

You will still have a wait when the user starts the app but no error. Again I am assuming this is SQLExpress.
