Need Help Clicking Button On Webpage

ok, i can click the button just fine programmatically... but when i click it... i get a pop up approval box... is there a way around this?



<input type="image" name="ctl00$ctl00$Main$Main$incomingRequests$ApproveSelectedRequestsButton" id="ctl00_ctl00_Main_Main_incomingRequests_ApproveSelectedRequestsButton" src="http://x.myspace.com/images/approveSelected.gif" onclick="return confirm('Are you sure you want to APPROVE the selected items?');" style="border-width:0px;" />



the "onclick" event is what i want to get around...
