I am developing a Tool using Add-Ins in order to get the coordinate where user clicks on map ( through OnMouseDown event), but I want to do some operations before getting coordinates in another method. I try to explain my problem with a simple example. for example, I want to see a message box that will be called from a method ( msg method) and then user click on map and get coordinates using OnMouseDown event. my problem is that the first time that i click on tool's icon i see a message box (" hello") but the second time that i click on tool's icon, it does not show message box and tool just call OnMouseDown event.
( as i told, i do not want to have message box in OnMouseDown event)
please help, thanks in advance
