This one dialog box contains a fixed segment, located in the left-hand part of the dialog, where all of the controls inside will not change. One of the controls is a list box and as the user selects a single item from the list box, the controls on the right automatically change to correspond with the selection. One selection may cause the controls on the right to become a couple of input boxes. Another selection may cause the controls on the right to become a combobox and some check-boxes. Get the picture?

I would prefer to NOT have to paint and repaint my controls programmatically. I would like to draw each of the control sets in the resource editor and then come up with some easy way to just swap them in and out.

Has anybody out there done something like this? Any advice?

A_LaxmanDo you want to redirect the settings done in ipconfig.exe ???

The problem has nothing to do with ipconfig.exe itself. It was only an example.
I want to be able to call any program (like ipconfig.exe or anything else that returns text) from my program and receive the result.
