Prblem with Zooming

Discussion created by mylouch on May 7, 2014
I buit a GUI. This GUI able the user the enter the following parameters:
* the name of the point
*  its longitude
* its latitude
and other parameters (all are input from a Textbox)
This GUI has also an "add" button which when clicked display the point on the map. Actually I have two major problem
1- When zooming the displayed point disappear (I know that I have to deal with map extent but I didn't know how
2- I  want to add the entered parameters in a table so how can I do that.
Those questions may be evident but I not familier with programming in ArcObjects C#
I will appreciate your help
Thank you
