Solution 1

From MSDN (http://msdn.microsoft.com/en-US/library/878fcck9(v=vs.90).aspx[^]):
"To clear the error message, call the SetError method and pass in Empty for the String value."
I.e. add an Else block like:

VB

Else
    ErrorProvider1.SetError(combo_Process, string.Empty)

End If

I think your validation condition is wrong.

Instead of:
If combo_Process.SelectedIndex = 0 Then
try:
If combo_Process.SelectedIndex = -1 Then

The items are zero indexed. An index of -1 indicates no selection has been made.

You may also want to correct the spelling mistake in the error message as well ("Precess" = "Process").

Do This :

VB

'If No Error
    ErrorProvider1.Clear()
'End If
