copy and paste exceptions

[Administrator]

I've been noticing a few random copy and paste crashes lately with the edit control. I've done tweaking of any cut and paste functionality. Here is the stack trace:

any ideas?

System.Runtime.InteropServices.ExternalException was unhandled

Sorry... that was supposed to read: "I've done *no* tweaking of any cut and paste functionality"

Hi Travis,

The exception is thrown because of an issue in Clipboard.SetDataObject method. It is possible to workaround this issue by deriving from EditControl and using the action-keys binding feature. I have attached a sample that illustrates this. Let me know if this meets your requirements.

Thank you for your patience.

Hi! Ebenezer,

Does this sample and work around work for version 4.2.0.60?
