sendmessage中WM_KEYDOWN 消息如何使用，我想向一个记事本自动写一个字符如何实现??(100分)

谢谢

SendMessage(XXX.handle,WM_KeyDown,VK_Return(或其它),0)

可以查看tcxtfile类，帮助中有example

 postmessage(handle,WM_char,VkKeyScan('v'),0);

D5光盘上有个sndkey32单元，查找到将其copy到delphi5/lib目录，<br>里面有个函数SendKeys。ok,打开你的记事本。<br>uses<br>&nbsp; sndkey32<br>procedure TForm1.Button1Click(Sender: TObject);<br>var<br>&nbsp; handle:Thandle;<br>begin<br>&nbsp; handle:=findWindow('NotePad',nil);<br>&nbsp; handle:=FindWindowEX(handle,0,'Edit',nil);<br>&nbsp; SetForegroundWindow(handle);<br>&nbsp; sendkeys('v',true); &nbsp;//成功<br>&nbsp; //postmessage(handle,WM_KeyDown,byte('v'),0);<br>&nbsp; //postmessage(handle,WM_Keyup,byte('v'),0);//没有成功<br>end;<br>xiaomin说得对，改为这样就行了<br>&nbsp; postmessage(handle,WM_KeyDown,VkKeyScan('v'),0);

??又一个？
