When using a ComboBox set the AutoCompleteMode to SuggestAppend in the designer, when accessing the init of that form through a background worker, the following exception is thrown:
"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made"
I know how to fix the problem, but what I am asking is why an STA thread is required to set this property?
Note: This is using WinForms, .NET 3.5, C#
