Answer 2

I found same problem when i use form X button on forms right hand corner.

Error:
"An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll
Additional information: Value Dispose() cannot be called while doing CreateHandle()."

I try this solution and it works
I found 'form' property of "Cancel Button"  which assign as 'None'.

I add new exit button and do exitbutton_click event In that i call function as
'Close();'

this exitbutton i link to 'form property Cancel Button'

It works well when i click on form X button.
