• Visual Studio Express Editions Changed data saved, however old data retrieved.

  If I open SQL Express (in Server Explorer) I can see the value "Foo" in the database table exactly where it should be. I can run my program and retrieve the value "Foo" from the local SQL Express database and display it in the form. I can change the value from "Foo" to "Bleh" on the form and push a button that saves it to the database. While the program is still running I can open the SQL Express database in Server Explorer and see that the new value "Bleh" is stored in the database. However, if the program immediately accesses the database again it will retrieve "Foo" ...Show All

• Visual C# Why won't my variable initialize in an overriden function?

  OK, I'm having a very peculiar problem here. I've got a modified DataGridViewTextBoxCell where I want to override the GetFormattedValue function to handle complex types in my data source. The problem is that I can't seem to initialize simple datatypes inside this overriden function. Here's the code: protected override object GetFormattedValue( object value, int rowIndex, ref DataGridViewCellStyle cellStyle, TypeConverter valueTypeConverter, TypeConverter formattedValueTypeConverter, DataGridViewDataErrorContexts context){ Citation tempCitation = new Citation (); ARTData tempARTData = new ARTData (); ...Show All

  I have installed a single server (WORKGROUP) setup of TFS without any issues in the installation routine The only non-standard selection I made was not to enable the Team Foundation Alerts.

• Visual Studio Team System Newbie needs sample "clean-build" script to study and run

  Are there any samples of "clean build" scripts that I can run prior to allowing code check in (The code needs, at least, to compile withtout errors or it can't go into source control). I was unable to locate this type of script on the TFS RC disk. Also, where is the script language used documented TIA, Barkingdog There are no samples for this yet. We are comtemplating one but it will take time. The build script here is MSBuild which is the default build engine in VS 2005.

• Visual Studio WinFX extensions not removed by auto removal tool

  I would like to draw attention to the fact that the auto pre-release uninstall tool provided by Microsoft does not remove these products if they were installed on the client computer: WinFX extensions for Visual Studio beta 1 WinFX SDK beta 1 However it did remove WinFX runtime beta 1. This is highly inconsistent behaviour because, The SDK is useless without the runtime. WinFX extensions cannot be removed AFTER the auto uninstall tool has completed removing the other products as it fails with the message: "A network error occurred while accessing 'C:\WINDOWS\Installer\vsextwfx.msi' ". Trying to uninstall by running the original .msi ...Show All

• SQL Server Dynamic connection manager file name

  Hi There This should be an easy one i hope. I need to dynamically change the file name of my destination flat file connection everytime the package runs, obviously i do not want to edit the config file everytime. I think the best way to do this is by a script taks that sets the connection manager filename property with a variable that i dynamically populate. Is this the right way I just want to be sure that there is not an easier or better way to do this Thanx Yes, that sounds like a good approach. Don't use a script task though (because its not possible to do it with a script task), u ...Show All
