通过窗口的handle如何调用这个窗口的方法？(200分)

我知道一个窗口的句柄（handle），如何调用这个窗口本身的方法？

用 function FindControl(Handle: HWnd): TWinControl 返回 TWinControl.

如果知道它是TForm ,则可用下列代码返回TForm.<br>var<br>&nbsp; &nbsp;aForm:TForm;<br>&nbsp; &nbsp;aWin<br>begin<br>&nbsp; &nbsp;aWinControl:FindControl(Handle);<br>&nbsp; &nbsp;if aWincontrol is TForm then begin <br>&nbsp; &nbsp; &nbsp; aForm:=TForm(aWoncontrol);<br>&nbsp; &nbsp; &nbsp; aForm.ShowModal;<br>&nbsp; &nbsp; &nbsp; ......<br>&nbsp; &nbsp;end;<br>end;

接受答案了.
