// 给你一个参考程序看看吧,虽然写的不太好,呵呵
#include <windows.h>

LRESULT CALLBACK WndProc(HWND hWindow, UINT iMessage,
WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nShowCmd)

}

while (true)

//临时写的
#include <windows.h>
int main()
{
char caption[] = "Messagebox ";
char content[] = "This is a Message Box! ";
HWND hWnd = NULL;
MessageBox(hWnd,content,caption,MB_OK);
return 0;
}
