问题 Visual Studio 2008 has a Copy Web Site tool that remembers previous FTP locations that files have been copied to. There is a "Connections" drop down where they are listed.

问题 I want to give the user ability to choose from double buffering and triple buffering, because on some cards (or OS?) the triple buffering is enabled by default, and its causing some performance problems.

In Windows, there is the WGL for handling context creation, etc. 回答2: There are no such function in OpenGL. The closest what I
