    resources

    Does anyone know where I could find out how to link resources to my program (in windows). I can create the resource file but I'm not sure how to get it to link to my program. I have created an icon and created the resource file but how do I make the icon show up for my program instead of that default white window? Any help is appreciated! Thanks

    dunno what you're using, in vc it's just to add...
    if you link with 'link.exe' it's just to..uhm...link with it..
    then check out the hicon field of WNDCLASSEX and LoadResource() and you're all set..

    *deciphered version*
    Well, you first of all include the header with the stuff. Then, you go to your initialization code, and where you create and fill in a WNDCLASSEX struct, you fill the hIcon member variable using the return value of LoadResource().

    P.S. Personally, I think LoadIcon() would be more practical for this purpose...
    Just Google It. √

    I'm not sure if I understand...
    Heres what I get out of that:

    I must create a WMDCLASSEX object and then use

    Code:
    object.hIcon = LoadIcon();
    Could someone explain it more for a "junior member" and not a "Codetagerator" ? Thanks!

    hiya,

    those are win32 api's that you use, it handles all the stuffs for you. ie, it handles your icons so when you compile your app, it automatically includes/appends your icon into your exe, that's it.

    so when you call LoadIcon(...), it gets your icon on your resource file and includes it in your program,

    So in the main, I should just type

    LoadIcon(nameOfResource);

    It seems too easy Maybe I'm missing something

    Unless your resource name is in quotes, you must use the macro MAKEINTRESOURCE( ) for the conversion.

    Code:
    LoadIcon( GetModuleHandle( NULL ), MAKEINTRESOURCE( IDC_ICON ) );
    The first parameter is the handle to the application instance.

    Ok... It isn't working

    here's my code:
    Code:
    LoadIcon( GetModuleHandle( NULL ), MAKEINTRESOURCE( "icon.rc") );
    I have the resource file created and it compiles just fine but the icon doesn't show up in place of the default window icon. What's wrong?

    You have to chance your code a bit. For the first you can not use MAKEINTRESOURCE that way. If you are going use it, you have to first create a header file where you define the icon, like this:
    Code:
    main.h
    
    #define ICON_NAME 1
    Then you create a resource file like this:
    Code:
    main.rc
    
    #include "main.h"
    ICON_NAME ICON name_of_file.ico
    And here is the modified cpp file:
    Code:
    main.cpp
    
    #include "main.h"
    wincl.hIcon = LoadIcon (GetModuleHandle(NULL), MAKEINTRESOURCE(ICON_NAME));
    wincl.hIconSm = LoadIcon (GetModuleHandle(NULL), MAKEINTRESOURCE(ICON_NAME));
    That should get it to work.

    Or you could simply leave out the header file and load the icon like this:
    Code:
    wincl.hIcon = LoadIcon (GetModuleHandle(NULL), "ICON_NAME");
    wincl.hIconSm = LoadIcon (GetModuleHandle(NULL), "ICON_NAME");
