• SQL Server Bug Report: Expressions not deleted

  I've noticed that if you create a data flow task (such as a DataReader source) and then bind an expression to it, if you rename or delete the task the expressions bound to the task will disappear but still be in the DTSX itself. So, if your expressions stop parsing (if you remove a variable, etc.) you will get errors for these expressions which you thought should have been removed. The workaround is to re-add the tasks with the old names and go delete the expressions from the expression list. I suggest you raise a bug at http://lab.msdn.microsoft.com/ProductFeedback ...Show All

• Visual Studio VSS Lan Service working randomly

  Hi, The Lan Booster service works randomly here. Sometimes everything is ok, and sometimes, for the very same operations, for the same database/project and on the same system, I get the following message: Unable to use SourceSafe LAN service, performance of SourceSafe operations will not be optimal. The service is running on the system hosting the database. Known problem I'm not very familiar with DFS, but I think that you're accessing the database with a "generic" path, something like \\domain\dfsroot\vss , isn't it If yes, VSS LAN service is not going to work. The client takes the databae path in the form \\server ...Show All

• Visual C++ System.InvalidOperationException in System.Windows.Forms.dll

  Hi!!! I posted some days ago with a problem: I had this: I had a large C++ unmanaged application which I compiled and ran perfectly using Visual Studio 2003. Now, I want to compile and run it using Visual Studio 2005. When I compiled it in release mode everything worked fine, but I got about a thousand comiler errors when trying to compile it in debug mode.

• Visual C++ __event alternative

  The following page : http://msdn2.microsoft.com/en-us/library/6f01ek09.aspx says that __event -based event handling is deprecated. In that case, what is the best way to do event handling I have a class HWClass, that talks to a hardware device. Several other classes need to read from this hardware device. However, the reading is asynchronous and HWClass needs to notify the calling object if the reading process is finished. (Bt the way, this is native C++ and not CLR) Thanks! I can not see how the __event keyword would help you Also I can noit see that it is deprectated. Also it has nothing to do with p ...Show All

• Software Development for Windows Vista Designer Problems

  I’m experiencing some problems while working with wf in visual studio. Sometimes while building or rebuilding the solution, the build fails, and NO exceptions are given . Opening the workflow file (workflow.cs) will show an exception in the designer: “ Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information .” I don’t know what it means. However sometimes, restarting VS will resolve the problem, but then again…sometimes it doesn’t. The problem occurs for both state machine workflows and sequential ones. I’ve not used workflows with code separation. An other, not so funny feature is ...Show All

  Hi, I'd like to print only certain columns of a DataGridView. How would something like this be done I couldn't find any code examples. Thanks Ok i have managed that too.
