:omg: Its working now check knowledge base PRJ: Toolbar Buttons Don't Work When Using DoEvents Statement article in MSDN. PSS ID Number: Q147409 When the DoEvents statement runs in a Visual Basic for Applications macro, toolbar button commands will not run.

Actually i placed drawing code in ToolBar button. Now i moved to Button it is working fine.
