Hi @fang.jiali ,
As far as I know, Edge IE mode supports ActiveX controls except Silverlight. When open this ActiveX control in Edge IE Mode, is there any error message in Devtools? You can use IEChooser to launch the Internet Explorer DevTools to debug the content of your IE mode tabs. To use IEChooser, follow these steps:
- Open IEChooser.
- Open the Run dialog box. For example, press the Windows logo key + R.
- Enter
%systemroot%\system32\f12\IEChooser.exe
, and then select Ok.
- Enter
- Open the Run dialog box. For example, press the Windows logo key + R.
- In IEChooser, select the entry for the IE mode tab.
In addition, have you tried setting MB_DEFBUTTON, it can set the default focus on the specific button of the message box.
Best regards,
Xudong Peng
