SEHException

[Raghavendra Bathal]

We are using Syncfusion 3.3.0.0 controls in our project.



But we are urgently facing an issue. Our application is throwing

System.Runtime.InteropServices.SEHException.



This link gives us the idea about the bug: -

http://support.microsoft.com/kb/897298





In our solution, we found that we are not using visual styles (Application.EnableVisualStyles())



But it is possible that Syncfusion might in turn may be making use of such a command.

Are you aware of any such issue with your components?

Please let us know, urgently.


A fatal error happened in

[namespace].AppMain_ThreadException.



Exception type: System.Runtime.InteropServices.SEHException



Exception message:

External component has thrown an exception.



Exception stacktrace:

Well,

here is how Syncfusion is being used:-

public ComboBoxAce()
{
this.Style = Syncfusion.Windows.Forms.VisualStyle.OfficeXP;
}


thanks and regards,

Hi Raghavendra,

This issue has reported when using EnableVisualStyles().

Hi Rohit,

Thank you for posting query to us.

Using EnableVisualStyles and DoEvents will result in SEHException. Also, it will cause the same problem even if you do not use Syncfusion controls. Could you please upload us a minimal sample to reproduce the issue here?. This will help us to analyze the issue further.

Please let me know if you need further assistance.
Regards,
Jisha
