win32 error on application closing

[sjbrand]

Hello
After successfully viewing a WORD document using the latest version of the DocViewer (I downloaded today 2/6/2017)
when I exit the application I get the following error message from Visual Studio 2015 (I'm using VB):

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in System.Windows.Forms.dll
Additional information: Error creating window handle.

Any idea why and how to correct?

Thanks in advance.
Steve

Dear sjbrand,

Thanks for your inquiry.
I have tested the scenario with the latest Spire.DocViewer V2.3.2, but didn't encounter any issue.
We will appreciate it if you could tell us detailedly how you exit the application and the better to offer us a sample project.
That would be very helpful to investigate this issue.

Thanks,
Betsy

Thanks Betsy.
I exit the application by clicking a button that execute the "End" command.

Private Sub btnExit_Click(sender As Object, e As EventArgs) Handles btnExit.Click
End
End Sub

I am using the DocViewer version if that makes any difference.

I do not dispose of any components programatically? Do I need to do that after viewing/loading the documents and
before closing the application?

Thanks.
Steve
