Ribbon throwing exception in getHdc
posted

Just going through our application exception logs, and by far the most common error we are seeing is the ribbon throwing exceptions. The two most common are ArgumentException (Parameter is not valid), and OutOfMemoryException. We have about 100 users using the application over citrix, and we're seeing these errors multiple times daily. Visually the result is that the ribbon isn't drawn, instead showing a white rectangle with a black border and red cross through it.

Our application is a WinForms application, currently using Infrafistics 2018.2. Its an MDI application using a master Ribbon on the MDI parent, with additional ribbons being merged from child forms.Merging takes the form of both new tabs, and new groups within existing tabs.

Here are some sample exceptions and stack traces:

ArgumentException

These always end up in GetHdc
