<br>内容：你的意思是不是在EXE和DLL里自定义同一消息.然后让DLL发送给EXE,通过参数传递啊?<BR>可是在DLL里怎么得到我的EXE的句柄呢?望大侠不吝赐教.多谢了.<BR>

<br>内容：exe要得到DLL中的变量，你只需在DLL中输出一个函数，返回这个变量，然后在exe中调用这个函数不就行了吗？<BR><BR>要写hook，先要熟悉DLL的编写！

<br>内容：LRESULT CALLBACK myhookproc(int nCode,WPARAM wP,LPARAM lP)这就是HOOK函数<BR>在EXE中，你把EXE窗口的句柄作为SetKbdHook（）第二个函数，在DLL中你用一个全局变量的窗口句柄保存下来
