I''m working on a program with a dialog box but I can''t seem to get the button to do what they are supposed to do. What I want: 4 Buttons: OK, Cancel, Readme, About OK -- goes to next step Cancel -- ends program Readme -- opens another dialog box with info on how the program works About -- Made by ... 2004, Version 1.00 In the resource editor I put down the buttons. Respectively, the button''s ID are IDOK, IDCANCEL, IDC_BUTTON1, IDC_BUTTON2. In the dialog''s callback, IDOK and IDCANCEL work just fine and do what they are supposed to when I click on the button. However, with the IDC_BUTTON1 and 2 I need to do a #define line at the top of the file. Okay... I decide to set the defines as such: #define IDC_BUTTON1 1001 #define IDC_BUTTON2 1002 My problem is, I can never get both buttons to work, and I get strange behavior by doing things that I think shouldn''t matter, such as changing the order of the #defines or the cases in the callback or even where the button is placed on the dialog box. When I swap the #defines, the callback''s switch statement will choose the wrong case. I think the solution has something to do with the numbers in the defines, but I don''t really know what they mean since I learned this from examining sample code. Can anybody explain what''s going on with using dialog box buttons?
