win32-為什麼不能創建出對話框

為什麼不能創建出對話框

#include

int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
CreateWindowEx(0,TEXT("#32770"),TEXT(""),WS_OVERLAPPEDWINDOW,
50,50,100,100,NULL,NULL,hInstance,NULL);
return 0;
}

最佳回答：

你需要按 Win32 程序的框架來，不可能在 console 來顯示其它窗體吧。
