• Visual Studio Express Editions Database problems: Save data, Change table definition

  Although a problem was recognized months ago regarding saving data, I'm disappointed that the Start Page "How Do I... (Database updating) still has a serious error and several suggestions are still floating around to resolve. Forum messages show this is causing a great loss of productivity with programmers and companies. See below for another problem. My past experience is with VBA and 2003 Net, using Excel as a database. Basics: 1. There are two separate items utilized by computer applications: -Definitions (object names, properties, methods etc.) -Data (actual information entered by user in various ways) 2. There are two per ...Show All

• Visual Studio 2008 (Pre-release) COM interop and WPF?

  I tried to use the SolidColorBrush class from COM as a test of some interop code I am working on. I was able to create an instance, but it only supported IUnknown not IDispatch, while a class I wrote myself does support IDispatch. The defailt for ComVisible is True, and the documentation shows no change in this for the whole hierarchy of this class. Is there something I am missing on this Would you expect to be able to get an IDispatch for an instance of SolidColorBrush Using WPF from COM isn't a scenario we've tried to enable (or plan to); as far as I know we don't have any code that tries to either enable or disable it.

• Visual C# Nice Threads!

  I could really use some help here... I am using C# 2005 and have created a splash screen that runs on a seperate thread. I can invoke the splash screen in the Main() method, but then I can't get rid of it! I am attempting to put a line in the Form1_Load (or maybe Form1_Shown) that calls a static method in the splash screen to close that form. But, when I do so, it complains about an invalid cross-thread operation. How can I get this screen to close Here are the relevant parts to my splash screen: // Static Public Method to launch Splash Screen static public void ShowSplash() { if (ms_frmSplash != null) return; ms_Thread = new Thread ...Show All

• Visual C# Looking for the equivalent of C++ MyClass::MyMethod ?

  Hi, Here is my problem: I've 3 classes using this hierarchy: ClassA <= ClassB <= ClassC ClassB has a method T which is overriden by the ClassC . With a ClassC object : I need, from the ClassB , to call the method implemented in ClassB and not the one implemented in ClassC . Actually, if I wrote, from ClassB : this.T( )   then the implementation of ClassC is called because of the virtual / override mechanism. If I call base.T( ) it try to call T( ) from ClassA . So, how can I call the ClassB's T method In C++ we can write ClassB::T( ) ... so perhaps there is an equivalent in C# Thanks in advance, Nicolas M. ...Show All

• Windows Forms Shell Extension Context Menu in C# strange error.

• Visual Studio Express Editions Any way to simulate a key being pressed?

  I'm wondering if there is a way to simulate a key being pressed, such as ENTER. I need to do this without targetting a specific window, just simulate as if somebody hit enter on the keyboard. I cannot target the window (or more like I don't know how) because I'm not creating the window. It's a print dialog that is created by the FaxServer object. Any ideas I know that simulating enter would certainly not be the best answer (without targetting), because any number of things could happen to screw it up, but it's my last resort. Thanks. What about SendKeys.Send( "{ENTER}" ) ...Show All

• Visual Studio Team System Unshelving error

  When I try to unshelve one of my shelvesets I get: "Error - No changes unshelved."  Any ideas what might cause this First, if I wanted to update my older unshelved file set with what is currently checked into the repository without having to check the files in, how do I do that from VS >> Unshelve your changes, do a get (this will cause a merge), then reshelve your changes.
