i have a class that its parent is CWND.
i wrote a function for WindowProc that in it, i have an if statement for message parameter.
the function works for WM_MOUSEMOVE, WM_LBUTTONDOWN and ... and i can get the message and do my action, but i have problem with WM_MOUSEWHEEL.
there is no message generated for this message and so i cant write my function for wheel.

i should add this words that, when i work with an Application, i have no problem and the WM_MOUSEWHEEL works properly, but in my usage, the class is in the ActiveX Control and it should be a window for this control.

thanks

如果您的使用正确且任何其他问题都可以删除您的WM_MOUSEWHELL，请使用Visual Studio上安装的SPY ++。您可以在工具栏上找到带有日志消息的窗口，并仅检查鼠标事件。您可以激活窗口并执行鼠标滚轮处理。当你可以检测到WM_MOUSEWHEEL事件发生的地方......



我希望这会对你有所帮助。

I hope this will be of help to you.
