VB OpenGL绘图
要想在VB6.0中使用OpenGL绘图，必须先下载一个SDK,名字叫vbogl.tlb。我用的版本是2.1，这个月要出3.0版本的了。
下载该文件后，直接在VB6.0“工程”-“引用”里面引用
1、在form中加入一个PictureBox控件
2、要在Windows里面使用OpenGL，必须先进行像素格式设置，函数代码如下
Dim hRC As Long’全局变量
'启用OGL
Sub EnableOpenGL(ghDC As Long)
On Error GoTo Err
Dim pfd As PIXELFORMATDESCRIPTOR 'pfd像素格式设置.
ZeroMemory pfd, Len(pfd)
pfd.nSize = Len(pfd) '大小
pfd.nVersion = 1 '版本
pfd.dwFlags = PFD_DRAW_TO_WINDOW Or PFD_SUPPORT_OPENGL Or PFD_DOUBLEBUFFER '标志
pfd.iPixelType = PFD_TYPE_RGBA '像素类型
pfd.cColorBits = 24 '颜色位数
pfd.cDepthBits = 32 '位宽
pfd.iLayerType = PFD_MAIN_PLANE '图层类型
Dim PixFormat As Long
PixFormat = ChoosePixelFormat(ghDC, pfd) '选择设备中最匹配我们所设置的像素
SetPixelFormat ghDC, PixFormat, pfd &nbs

使用c#语言在.net平台生成的dll是基于MSIL的二进制代码，通常情况下是无法被native的语言和程序调用的（例如vb，vc，delphi）。但是一般来说windows上native的程序都是可以直接使用com对象的。通过.net平台提供的一些工具，可以为其伪造一个com接口并注册到系统中。此时，可以在native的程序里，通过这个伪com接口来实现此. ......
