Hello Kaspatoo,
I think you misunderstood my questions below, but it was a nice consideration from you.
Please note the following scenario in order to be more clear with my questions:
- I have four layers loaded in ArcMap 9.3 and the 3rd one called "X"
- I generated a form that contain a datagridview in order to preview the details of the selected X feature when a user click on the map. (same functionality as Identify tool)
- I want to get the "OBJECT ID" of the X feature that lies under the xy of the mouse click (polygon feature that covers the location of the mouse click) in order to query the details of the this X feature from my personal datatable and not from the layer in arcmap.
I think it is possible to get the "Object Id" of the feature located under the mouse click. Isn`t it?
The second think is that: I want to flash the selected feature in ArcMap programmtically, So how would be the code to do that?
Please help...
