VintaSoftTwain disabling visual styles

[marshallandy83]

Hi,

We have a problem with VintaSoftTwain disabling visual styles in our application. This is causing the DevComponents DotNetBar controls to crash when being redrawn.

Here is the message/stack trace:

Visual Styles-related operation resulted in an error because visual styles are currently disabled in the client area.

Code: Select all

    at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
    at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Unfortunately, since the DotNetBar code is third-party, I cannot make any changes to it.

Has anyone come across this problem before?

Thanks,

Andy

Hi Andy,

Could you send us a small working project which demonstrates the issue? If yes, please send it to support@vintasoft.com.

Best regards, Alexander

Hi Alexander,

Thanks for your reply. Unfortunately, unless you have the DotNetBar controls, you will not be able to reproduce the issue, so I don't think sending you an example project would be helpful.

Is there a way to suppress the progress bar dialog box when scanning?

Thanks,

Andy

OK, I found the ShowIndicators property but setting this to false does not solve the problem.

I think DevComponents allows to evaluate their DotNetBar components. Could you send us a project with evaluation version of DotNetBar components?

Best regards, Alexander
