给窗口发消息：<br>SendMessage(handle,message,Wparam,lparam);<br>Handle为窗口句柄，message为消息类型，<br>wparam和lparam为消息参数；<br><br>

这个应该很简单啊：<br>var<br> h:Thandle;//指定窗口的句柄<br> p
char;<br> size:integer;<br>begin<br> size:=128;<br> getmem(p,size+1);<br> sendmessage(h,wm_gettext,size,p);<br> Showmessage(string(p));<br> freemem(p);<br>end;<br>其实使用这个消息等于用GetwindowText<br>
char;<br> size:integer;<br>begin<br> size:=128;<br> getmem(p,size+1);<br> sendmessage(h,wm_gettext,size,p);<br> Showmessage(string(p));<br> freemem(p);<br>end;<br>其实使用这个消息等于用GetwindowText<br>

to coolx:<br>但我这样用却出错，提示wParam和wLParam都不能用Integer和PChar！<br>why?

WM_GETTEXT好像是针对控件的消息，具体使用可以这样做。<br>var<br> h:HWND;<br> buffer:array[0..255] of char;<br>begin<br> h:=FindWindow('TForm1','MyForm');<br> if h<>0 then<br> SendMessage(h,WM_GETTEXT,255,LongInt(@buffer));<br>end;

对不起，我没注意，这样：<br>var<br> h:Thandle;//指定窗口的句柄<br> pchar;<br> size:cardinal;<br>begin<br> size:=128;<br> getmem(p,size+1);<br> sendmessage(h,wm_gettext,size,integer(p));<br> Showmessage(string(p));<br> freemem(p);<br>end; 应该没问题，或者按liguang的方法也行。<br>
char;<br> size:cardinal;<br>begin<br> size:=128;<br> getmem(p,size+1);<br> sendmessage(h,wm_gettext,size,integer(p));<br> Showmessage(string(p));<br> freemem(p);<br>end; 应该没问题，或者按liguang的方法也行。<br>
