• 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.

I made a binding for the D language using interfaces that inherited from the IUnknown int ...Show All

We can write: using PlantId = Int32; using AnimalId = String; class Plants : List<PlantId> {} class Animals : List<AnimalId> {} void useList(Plants p) { PlantId firstPlant = p[0]; TextBox1.T ...Show All

• Visual Basic How to make slideshow transition with Picturebox

  You've seen those fancy wipes, fades, cut and swirls in slideshows... now, how do you do it with the Picturebox Yes, that's because the picture box is not designed to be moved like that, and it's very existence adds overhead.  And yes, Windows Forms have a double buffer mode that gets rid of the flicker, when you draw the bitmaps yourself.  So, you're right, that's one way in which the new framework h ...Show All

• Visual Studio 2008 (Pre-release) save canvas to image?

  Hi all, question... does anyone know if it is possible to save the visual state of a canvas (or some other such visual object) as an image (then save to harddrive).
