I am supposed to update a very old program written in Fortran which is set up as a Visual Studio Project using a .rc-File.

The old version of the program used a GUI having 2 radio-buttons Var1 and Var2 that could be selected( only one of them). Now I want to expand the GUI having 7 radio-buttons ( var1-var7) from which still only 1 should be able to be selected.

Since I have no Idea neither of Fortran nor of the rc-File-type I tried to do it like that:

enter image description here

having done that I get the following problem: - the radiobuttons (var1-var7) are there and can be selected ( one at a time) which is fine - Only when I press Var1 or Var2 (the old ones) the value-id of that button gets updated so that I can use these value for later use. Var3-var7 don`t get updated.

Does anybody know what I did wrong?

Look in your code for something like GetDlgItem(IDC_GASVEL). There probably aren't any for GetDlgItem(IDC_PRESS) .. GetDlgItem(IDC_IGSTR) as you have only added the entries in the resource (RC) file and not the code file.

to check whether the radio button is set, have a look at how IsChecked is used. To set a button, use SetCheck
