If your form can be placed on a menu, setup three menu locations, one for each customization.
Then use the LaunchForm method with three different menu locations from the button click events.
ProcessCaller.LaunchForm(oTans, "UDMenuID")
If it is a child window you may need to work with the sub-process maintenance or pass arguments into one form that will determine the layout and functionality.

from the picture you can see three highlighted button, these three buttons will call the same form which is PackSlipBrowseForm. I want to call my customized form when click Manual Selection Button. but the other two buttons will call the base form.
Any suggestion to do this?
