could you tell us which version of the sdk c# wrap you used? Test the latest c# wrap and c++ sdk, it is worked.

please use the latest c# demo to try again.

Hi,&nbsp;

&nbsp;

Thank you for the response!!

I have taken latest version of C# wrapper and C++ SDK.&nbsp;

&nbsp;

And also,&nbsp;C# zoom\_sdk\_demo application is working as expected as well!!&nbsp;

&nbsp;Zoom\_sdk\_demo is wpf application by my application is C# winform application.&nbsp;

&nbsp;

should i use wpf strictly to use all the features of SDK? but my product is in C# winform app.&nbsp;

So i would like to request help to work this on C# winforms.&nbsp;

Thanks in advance!!

root cause:

winform app is based on MFC and not friendly with native win32 windows.

we will fix this issue in next release.

workaround:

you can&nbsp;add a message filter in your app to process the&nbsp;WM\_GETDLGCODE windows message.

when you recv this message,&nbsp;please return&nbsp;DLGC\_WANTMESSAGE as the return code.&nbsp;

thanks

dats.
