已知句柄，取得文字内容可以用GetWindowText，清除内容可以用SetWindowText。<br>function SetWindowText(hWnd: HWND; lpString: PChar): BOOL;<br>function GetWindowText(hWnd: HWND; lpString: PChar; nMaxCount: Integer): Integer;

总感觉这种说法不太不太……<br><br>Delphi里面自然就是RichEdit了，VC里面RichView其实一个View，而不是控件，如果是RichEdit，一点废话，<br><br>后面的楼上兄弟很清楚了<br><br>PostMessage(Handle, WM_SETTEXT, 0, Integer(PChar('')))<br><br>或者<br>PostMessage(Handle, EM_SETSEL , 0, 0);// 全选<br>PostMessage(Handle, WM_CLEAR, 0, 0);// 清空<br><br>个人看法，仅供参考

如果RichView.Flags中，rvflCanProcessGetText为True，那么可以用WM_SETTEXT，否则就要Hook进入该RichView所在的进程才能想办法做到啦<br>SendMessage(Handle, WM_SETTEXT, 1, Integer(PChar('')));<br> ^^^切记[
]<br>另外，WM_CLEAR清除的是当前选中部分的内容，这里显然是不适用的

将 RichEdit 内容保存在 lpText 中，然后清空：<br>var<br> lpText: PChar;<br>begin<br> SendMessage(hWndRich, WM_GETTEXT, 255, lpText);//取内容<br> ...<br> SendMessage(hWndRich, WM_SETTEXT, 0, ''); //清空<br> ...<br>end;
