Hi Paul
Exact this subject where adressed only a week ago. The best way possible in
MapBasic is from what I got out of it:
* create a Toolbutton when you press a button i your dialog.
* then set the Map window to the front
* call the tool with Run Menu Command ID ####(ID from your
create toolbutton definition)
* when the user clicks in the map mapbasic processes this in
the toolhandler routine as defined in the toolbutton create command. Use
this handler to store your coordinates by using CommandInfo(CMD_INFO_Y) and
CommandInfo(CMD_INFO_X).
* Then call back your dialog from before and remove the
toolbutton by using alter buttonpad statement.
That should do the trick.
