Hello Everyone!

I'd like to begin the adventure on the programming with mappoint 2006 Europe. I have met several problems in my demo project and hope to get some directions to solve them.

1) Is there a way to "prohibit" the user to modify the pushpins and lines generated by the software? We need the "zoom" function by the left key, but not able to disable the actions like "move", "drag", etc

2) Without "return TRUE" in the BeforeClick event handler, the pushpins and lines can be selected by mouse left/right click. While as we need our own menu, we let BeforeClick event handler "return TRUE". Now the menu does not popup. But in this way, how to select the pushpins, and lines ?

Thank you very much!

Hi,

to prohibit a user changing things you can do several things. In selectionChanged you can check what a user has selected and deselect it by selecting something else. eg create a pushpin somewhere in the ocean, select it and delete it.

you can also place a transparant panel on top of the control. then the panel receive all mouse and keyboard events and you have full control.

for your other question, I'm not sure I understeand completely. you can have in onBeforeClick your own popup menu. best is to do it outside the event handler. for example by posting a message to a custom message handler where you popup your menu. if you set cancel = true then mappoint will not popup his own menu.
