MFC/C++ Change width of a item via code

Question

So I have a dialog which contains two ListControls.

I want to make one ListControl only visible to some people.

Lets say I have ListCtrl1 and ListCtrl2 (ListCtrl2 only visible for some people):

• When you are allowed to see both, ListCtrl1 is on the left and ListCtrl2 is on the right.

• When you are only allowed to see ListCtrl1, it should fill the whole Window alone.

I need to do this in the code, because only there I can check who is allowed and who not.

Answer 1

Create your dialog as usual with the resource editor with both list controls.

If you want to show only ListCtrl1 then use ShowWindow to hide ListCtrl2 and MoveWindow to resize ListCtrl1 so it covers the whole area.

You probably also need GetWindowRect and ScreenToClient.
