Placing a message box in an error trap can provide useful debugging information, but it doesn’t allow you to return to the subroutine or function to poke around and further debug the code. This version of a message box expedites design-time debugging by breaking execution if the developer presses OK:

 Private Function MyDebugMsg(ByVal aMessage _	As String) As Boolean	' This function is used for expediting 	' development	If MsgBox(aMessage, vbOKCancel, _		"OK puts you into the Error Trap") = vbOK Then		MyDebugMsg = False	Else		MyDebugMsg = True	End IfEnd Function' Sample subPublic Sub SetColor()On Error GoTo SetColorError' body of the subroutine would go here,' force an error to demonstrateError 5SetColorErrorExit:	Exit SubSetColorError:	' In an error trap place this line in addition to any	' other error handling code	Debug.Assert MyDebugMsg(Err.Description & " in SetColor")	'other error handling code	Resume SetColorErrorExitEnd Sub
