• Visual Basic File system watcher

  I have a win program that sits in the system tray, watches for new files in a folder, and then processes and appends info to them. I am using the file system watcher control in VB.net 2005. Everything works fine when you just copy a file into the folder for testing. However, when I use the program that will be creating the file, it throws an error saying that the file is in use by another process. Is there anyway I can have my app check if the file is in use, and wait until it isn't before it does it's processing Is there something else I'm missing Right now all my processing code is triggered from the file system watcher control's file crea ...Show All

• Windows Forms Avoid prompt of template save OR what makes word to prompt .dot file save?

  Hi, We've developed VSTO 2005 Word Application, which uses our own template file(xyz.dot). However, when users close the document, they get prompted for save of normal.dot file - WHICH we don't use in our application. This happens only for few users. (If they open normal word doc, there is no prompt). This is the sequence of events which happen in Doc_Load - Create custom toobar dynamically - Enable/Disable menu items , based on few rules - Attach our application's template ( xyz.dot) - Attach an XML Schema Activities during doc edit session, would be one of the above only. No additional steps being done. My Questions: ...Show All

• Software Development for Windows Vista Root Namespace for VB Project

  It seems that I am required to have a Root Namespace specified in the project options for my Workflow Assembly. If I do not have a root namespace specified I receive the following error: option 'rootnamespace' requires ':<string>' I have currently only tried this in VB.NET and not C#, so I don't know if this happens in both languages. Is this some sort of a bug I like to expicitly declare my namespace for each class and remove the root namespace. This used to be a bug in beta1, but should have been fixed in the latest beta2 release. Shelly ...Show All

• Visual Studio Express Editions Project Files

  MSVC++ 6.0 had a wonderful feature in which during the compile process of the main code (which had, of course, user #include file(s) in it), the environment would identify ("discover") *all* header files upon which the project was based - automatically. Do the later MSVC versions have this capacity If so, how do I set up my environment to make this happen and where in the IDE would these files be displayed Thanks. This could be done using multiple ways in VC2005. Some using the IDE and other using a compiler switch (/I). Take a look at http://msdn2.microsoft.com/en-us/library/73f9s62w.aspx where ...Show All

• Visual C++ Timing the compiler

  The Visual C++ 2003 linker has an undocumented /TIME option which reports how much time the linker has spent on each phase. Is there a corresponding option for the compiler   It would be helpful to know exactly how long each file took to compile.  I have a 146-file project taking nearly 30 minutes to build; it would be quite helpful to find out where the delays are. You can add the (also undocumented) /Bt option to the command-line: this will give you some idea of how long the front-end (c1xx.dll or c1.dll) and the back-end (c2.dll) take to compile each file. ...Show All

• Visual Studio Team System After VSSConverter, the .sln file still point to VSS, not the VSTS Source COntrol

  Hi: Maybe I missed something, but I have a question like to ask everybody who know the steps. I have a Visual Studio 2005 solution with 2 projects and 1 web site.  This solution was originally controlled by Visual SourceSafe 2005 and worked since Dec CTP released.  Now I want to change the source control to Team System Version Control, which is in the TFS April CTP edition. I followed the steps in Migration Walkthroughs with Walkthrough: Preparing to Migrate from Visual SourceSafe to Team Foundation and Walkthrough: Migrating from Visual SourceSafe to Team Foundation The migration is fine, the errors showed tha ...Show All

Error PRJ0019 : A tool returned an error code from "Performing registration" PantherConfig I have gone thru a number of links providing solution for this but couldn't get correct solution.

• Visual Basic Exception handling doesn't catch errors

  I seem to be missing a fundamental point regarding exception handling. My understanding is that when an error occurs, it can be caught by Catch without abnormally terminating the program. Mine will always abnormally terminate when an error occurs. An example is below. When the connection fails to open, the application breaks instead of executing the Catch block. Why Try cnSQL.Open() xMainMenu.ShowDialog() Me .Close() cnSQL.Close() Catch exc As Exception MessageBox.Show("Error Connecting to Database: " & exc.Message) intLoginAttempts += 1 MsgBox("Login Failed, " & maxLoginAttempts - int ...Show All
