WinForm crashes Visual Studio in Design Time

Mike Fleisch posted over 2 years ago

Hi,

i have a very big form with a lot of Infragistics-Tools, changed it several times, all worked very good ... but since today i am not able to open the form in design time - visual studio needs some time to open and after displaying the form with no response visual studio crashes und restarts.

In the windows logfile i found the following errormessge:

Anwendung: devenv.exe
Frameworkversion: v4.0.30319
Beschreibung: Der Prozess wurde aufgrund einer unbehandelten Ausnahme beendet.
Ausnahmeinformationen: System.ArgumentNullException
bei Infragistics.Win.UIAutomation.Stubs.EditorControlUIAProviderStub..ctor(Infragistics.Win.UltraControlBase, Infragistics.Win.EmbeddableEditorBase, Infragistics.Win.EmbeddableEditorOwnerBase)
bei Infragistics.Win.UltraWinEditors.UltraToggleEditorBase.CreateUIAutomationProvider(System.Object)
bei Infragistics.Win.UltraControlBase.get_UIAutomationProvider()
bei Infragistics.Win.UIAutomation.UiaProviderControlNativeWindow.WndProc(System.Windows.Forms.Message ByRef)
bei System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr, Int32, IntPtr, IntPtr)

Anything happens in the ctor of EditorControlUIAProviderStub => ArgumentNullException

I have tried almost everything:

Copy design-code to a new form
Creating a new solution with one form an this designcode
restored 1 year old code with a older version of this form => same error
Reinstal Visual Studio
upgrade Visual Studio von 2019 to 2022
Reinstall Infragistics Tools 2020.2

always the same problem, Visual Studio crashes

I am running out of ideas und would realy appreciate any help.
THANKS,
Mike

Hello Michael,

I have included the sample Form and its designer into a new Windows Forms application on my end, and in doing so, I am able to load the designer without Visual Studio crashing with the error you are reporting. As proof, I am attaching a screenshot of what I see after including it on my end.

Since I am unable to reproduce the behavior, I have a few questions about your environment in this case. Can you please provide information on the following?

1. What is the specific version of Infragistics for Windows Forms 2020.2 that you are testing against? My tests were made against the latest service release in 20.2.20202.82. I also tested against the latest version of 22.2 and was not able to reproduce any error there.

2. What operating system is your machine running?

3. What version of the .NET Framework are you targeting? Judging by the error message, it looks like it’s probably 4.0, but I’m not certain on this.

Please let me know if you have any other questions or concerns on this matter.
