In the Callback class I have a sub set up to handle every time the OLE window changes which works fine, now the fun begins. I set up another sub which takes a string from the sub receiving the callback message, it then uses this string to select a control on the main form like so

Dim pnl as Panel = Mainform.pnlLegend.Controls.Item({String})

When ever it gets to this line it throws the error "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made".
