编辑框的问题：如何设置编辑框文本？
 

CWnd *trywnd=this->FindWindowEx(NULL,NULL,"#32770","try");
CWnd *edit=this->FindWindowEx(trywnd->m_hWnd,NULL,"Edit","");
if(edit->m_hWnd)
{
edit->SendMessage(WM_SETTEXT,0,(LPARAM)(LPCTSTR)("fanqing"));


}
上面代码我测试过了成功.
但是使用
edit->setwindowtext没有成功.证明了楼上的一句话SetWindowText cannot change the text of a control in another application.

MFC的SetWindowText应该和SDK的SetWindowText类似，请看SDK的SetWindowText：

The SetWindowText function changes the text of the specified window's title bar (if it has one).
If the specified window is a control, the text of the control is changed.
（注意：--->) However, SetWindowText cannot change the text of a control in another application.
