I am using DisplayAlerts=False and when I set it to true, the alert does popup allowing me to save the clipboard contents for later use. Still it's a difficult call to understand why in VBA code this same process is so simple and works like a champ. But from VB.NET this is all but impossible. I found that by launching AutoCAD I could copy the clipboard into the model space but the formatting, borders, colors, etc... are all missing. No gridlines or nothing like when we were running this from a macro with Excel.
Oh yes, I tried the suggestion in your second post and it was not the answer. Thanks anyway.
