    How do I add a variable to a control ?

    After I've designed a dialog with say, a ListBox... How do I connect the resource (display) with the CListBox variable in my main dialog class ?

    In theory, there is no difference between theory and paractice; in practice there is.

    Re: How do I add a variable to a control ?

    The code is too complex to paste, but here is the problem:

    I created a dialog Project. In the main dialog I placed a ListBox control.
    I want to add a varaiable to the control so I can update the information displayed in it. I tried using the class wizard, which creates the control variable. But I can't access the variable from within my main dialog even though it is a member of that dialog.

    I was thinking that if I declare the CListBox m_listBox in the public section of the main dialog, and then attach is to the visual control, it might work. At least, it would help me understand it a little more if it doesn't work.

    Understand now ?

    Yeah, that's what I was looking for. I've done it before but couldn't remember. What DDX function is used for a CListBox ? DDX_Text isn't the right one...

    I'm still having the same problem...

    Code:
    CDialog {
    ...
    
    public:
    
    CListBox m_ListBox;
    
        static BOOL CALLBACK GetWndName(HWND hWnd, LPARAM lParam){
    
            m_ListBox.AddString("HEY!");
        
         return TRUE;
      }
    ...
    }
    So I can't access the ListBox in that function. They are both declared in the public section of the same dialog. What's the deal?
