在VC++的WIN32 Application 下的修改过了
可以正常运行~~~

你把调试错误信息帖上来
我估计是回调函数在使用时，参数不必再加上类型在前
LRESULT CALLBACK WinPinkeProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
)
而是
LRESULT CALLBACK WinPinkeProc( hwnd, uMsg, wParam, lParam )

int WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow
)

定义问题已解决~~
