• Visual Studio 2008 (Pre-release) WinFX CTP install issue

  Cheers, I am posting to this group because I have not found any groupe dedicated to general WinFX issues. I am having problem installing WinFX January CTP. When I launch the install, the window with progress bar saying "Setup is loading installation components. This may take a minute or two." shows up, advances to 80 percent, and CPU usage jumps to 100%. It is impossible to kill the process. Task manager doesn't kill it, taskkill doesn't kill it, nor Process.Kill() from .NET framework. The only way to stop is to restart the machine. I've got the same problem with the Februrary CTP. The machine is WinXP Professional, with o ...Show All

• Visual Basic Using virtual function in VB.NET from C++ DLL

  Hi, I'm running into a problem when trying to use class interfaces from this library called Audiere. The library was written in C++ as virtual functions that were COM compatible. To use the interface you call a function in the DLL that returns a pointer to the interface (Factory ). They are bindings for Purebasic and Delphi that use the interfaces directly. I made a binding for the D language using interfaces that inherited from the IUnknown interface and it worked. Since .NET supports COM interop I thought this should work easily. I created the interfaces and marshaled them as IUnknown(I had to inherit from IUnknown to get it to work in D). ...Show All

• Windows Forms Disabling screen captures to the clipboard

  I am creating a windows forms application using VB.NET and want to prevent the users from being able to use Ctrl/Alt/Shift PrintScreen combinations to capture the data displayed on the forms. I found a way to use the ProcessKeyPreview Overrides to insert text onto the clipboard immediately after the screen is captured stating that "screen captures are disabled".  But I discovered that by opening any MS Office application, I can use the Office Clipboard to see that screen that was captured still in the clipboard. I have also seen that VB.NET 2005 has the My Computer namespace that allows clearing of the clipboard.  But is there ...Show All

• Windows Forms Type BindToObject

  It would appear that when ControlBindingsCollection.Add(string, object, string) is called, a BindToObject is placed in the "Changed" event handler of the dataSource object. The problem is that this object is not public so it's members cannot be accessed. I would like to be able to retrieve the orginal construction parameters from this object in order to serialize the binding (it's not [Serializable]). Is there a way to convert a BindToObject to something I can make use of Thanks, Ray The following articles may help:   http://windowsforms.net/articles/shapedesigner.aspx .   http://msdn.microsoft ...Show All
