我第一次用C++调用Windows API 来写窗口，但是我很郁闷，，我这个怎么米有窗口啊，，，大哥大们给帮忙看下。谢谢！

#include <windows.h>
#include <stdio.h>
LRESULT CALLBACK WinLogerPro(
  HWND hKeyloger,      // handle to window
  UINT uMsg,      // message identifier
  WPARAM wParam,  // first message parameter
  LPARAM lParam   // second message parameter
);
int WINAPI WinMain(
  HINSTANCE klg,      // handle to current instance
  HINSTANCE hPrevInstance,  // handle to previous instance
  LPSTR lpCmdLine,          // command line
  int nCmdShow              // show state
)

    WNDCLASS keyloger;

    keyloger.lpfnWndProc=WinLogerPro;
    keyloger.cbClsExtra=0;
    keyloger.cbWndExtra=0;
    keyloger.hInstance=klg;
    keyloger.hIcon=LoadIcon(NULL,IDI_ERROR);
    keyloger.hCursor=LoadCursor(NULL,IDC_CROSS);

    ShowWindow(hKeyloger,SW_SHOWNORMAL);
    UpdateWindow(hKeyloger);

        TranslateMessage(&msg);
        DispatchMessage(&msg);

}

没看出来有什么区别啊，大哥。。。我第一次的东西就这样傻在这里了。。。

ShowWindow (hwnd, iCmdShow) ;
        
    UpdateWindow (hwnd) ;

有，    ShowWindow(hKeyloger,SW_SHOWNORMAL);
    UpdateWindow(hKeyloger);

大家给看看啊！！！第一次啊。。。谢谢了！！

大家谁要是想要百度知道分的 可以去这里

好了解决了，在百度知道。

对了半天的程序..好像少了调用系统的程序..要不然程序什么都不能做..这个东西很少记得..都是改改..看来有时间还要好好弄弄了
