wince hook键盘按下捕捉不了

hook的dll代码:

可以成功加载dll里的函数KeyDetProc_InsHook,但是键盘按下时KeyboardProc竟然不能进入,求解决方法.
或是有一个hook键盘的例子我参考一下

LZ，你可以去我在CSDN的BLOG里看看，有一个例子。

[/Quote]谢谢,你的博客有十页呢,还没找到有关hook的,csdn的搜索功能不给力啊..

现在可以hook到了,我改在应用程序SetWindowsHookEx了

不过有bug:

hook KeyboardProc
hook key up
hook Get a Key
Prefetch Abort: Thread=83986170 Proc=80426ae0 'testKeydet.exe'
AKY=00000401 PC=00000000(???+0x00000000) RA=01bd1668(keydet.dll+0x00001668) BVA=00000000 FSR=00000005

LRESULT CALLBACK KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam)
{ 
 //	RETAILMSG(DEBUG_CODE,(L"hook KeyboardProc\r\n")); 
 	KBDLLHOOKSTRUCT *pkbhs = (KBDLLHOOKSTRUCT *) lParam; 
 	if(wParam == WM_KEYUP) 
 	{ 

 		RETAILMSG(DEBUG_CODE,(L"hook key up\r\n")); 
 	} 
 	if(wParam == WM_KEYDOWN) 
 	{ 
 		RETAILMSG(DEBUG_CODE,(L"hook key down\r\n")); 
 	}
 	RETAILMSG(1,(L"hook Get a Key\r\n"));
    return 1L;//CallNextHookEx(NULL,nCode,wParam,lParam); 
}

为什么这样子改一下就没有内存泄露了,wParam == WM_KEYUP和if(wParam == WM_KEYDOWN) 为什么都进入不了?

[/Quote]谢谢啊.最后一个问题:怎么把hook.dll里得到的数据传给应用程序,比如通知主程序现在按下了什么键
