Tried to upgrade the VBControlsDemo to VS .net 2003, got it to compile eventualy but then there was an error when trying to install it into XUnleashed, the DLL wouldnt register. And there are options in VB6 that I could not find in the new visual basic. So I ended up tracking down an old version of VB6 and am working on that. I got my plugin compiled and the names and GUID's changed to new ones.
If you get it to upgrade properly and still install please post your source..
When you upgrade after getting the MSDERUN.DLL there will be an error in the initilization method, just change XUnleashedGUI.IXUPluginHelper (line 56 i think) to XUnleashedGUI.XUPluginHelper and it will compile, but the dll wont register in XUnleashed

very discouraging. Anyways Good luck.
