Hi,I think you should add: CComModule _Module; //global CoInitialize(0); _Module.Init(0,GetModuleHandle(NULL)); AtlAxWinInit(); before you call AtlAxAttachControl() function.

Solved the problem... the Bitmap class can be cast into an HBITMAP & then selected as an HDC to be copied into the surface. Heres the fixed code: MemoryStream^ ms = gcnew MemoryStream(br->ReadBytes(TILE_BITMAPSIZE)); Bitmap^ bm = gcnew Bitmap(Image::FromStream(ms, true, true)); HBITMAP hbm = (HBITMAP)bm->GetHbitmap().ToPointer(); HDC src = CreateCompatibleDC(NULL); SelectObject(src, hbm); HDC dst; BitBlt(dst, 0, 0, Width, Height, src, 0, 0, SRCCOPY);

Thanks Luc, That did the trick. I was trying to use system before because I thought it was lined up, but courier worked beautifully.

Any .NET language is compatible. In fact there are other languages compatible, callable from managed (.NET) languages but that requires experience in these areas and I don't suggest it because no language is 100% compatible with another one ;)
