function CallBackProc(aHandle: HWND, aLparam: LPARAM): boolean; stdcall;<br>begin<br>&nbsp; //aHandle is the handle of a child<br>&nbsp; //do what you want<br>&nbsp; //for instance GetClassName<br>&nbsp; //aLparam is the parameter of the EnumChildWindows<br>end;<br><br>EnumChildWindows(aWindowHandle, aLparam);

对不起，写错了，<br>EnumChildWindows(aWindowHandle, @CallBackProc, aLparam);

是的。<br>EnumChildWindows(<br>hWndParent: HWND; {the handle of the parent window}<br>lpEnumFunc: TFNWndEnumProc; {a pointer to the callback function}<br>lParam: LPARAM {an application defined 32 bit value}<br>): BOOL; <br> <br>
