基于VC++6.0创立一个坐落顶层的SDI单文档界面使用，你可点击File菜单中的“Create New Frame”指令来创立顶层SDI使用，但封闭主使用后其它的窗口也将封闭，程序由Visual C++ 6.0变换生成，VC++编程学习源码，很好的参考资料。-VC++6.0 founded a is located at the top of the SDI single document interface using, you can click the File menu in the "Create New Frame" command to create the top SDI use, but closed the main use other windows will be closed, the program generated by the Visual C++ 6 converter, learning VC++ programming source code, a good reference.
