Resources, icon, resources....

OK now im lost, my tutorials aren't working, and this is where i turn to next: on my source code i have:

Code:

#include <windows.h>
#include "resource2.h"

const char g_szClassName[] = "myWindowClass";

// Step 4: the Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch(msg)
    {
        case WM_CLOSE:
            MessageBox (NULL, "Im sorry you have to leave", "i'm sorry", 0);
            MessageBox (NULL, "C'ya", "GoodBye", 0);
            DestroyWindow(hwnd);
        break;
        case WM_DESTROY:
            PostQuitMessage(0);
        break;
        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow)
{
    WNDCLASSEX wc;
    HWND hwnd;
    MSG Msg;

    //Step 1: Registering the Window Class
    wc.cbSize        = sizeof(WNDCLASSEX);
    wc.style         = 0;
    wc.lpfnWndProc   = WndProc;
    wc.cbClsExtra    = 0;
    wc.cbWndExtra    = 0;
    wc.hInstance     = hInstance;
    wc.hIcon         = NULL;
    wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
    wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+0);
    wc.lpszMenuName  = NULL;
    wc.lpszClassName = g_szClassName;
    wc.hIconSm       = NULL;

    if(!RegisterClassEx(&wc))
    {
        MessageBox(NULL, "Window Registration Failed!", "Error!",
            MB_ICONEXCLAMATION | MB_OK);
        return 0;
    }

    // Step 2: Creating the Window
    hwnd = CreateWindowEx(
        WS_EX_CLIENTEDGE,
        g_szClassName,
        "Dont ask im just testing functions",
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, 800, 500,
        NULL, NULL, hInstance, NULL);
        HICON hMyIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_MYICON));

    if(hwnd == NULL)
    {
        MessageBox(NULL, "Window Creation Failed!", "Error!",
            MB_ICONEXCLAMATION | MB_OK);
        return 0;
    }

    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    // Step 3: The Message Loop
    while(GetMessage(&Msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }
    return Msg.wParam;
}

Here is my resource2.h file:

Code:

#define IDI_MYICON  101

And here is my resource2.rc file:

Code:

#include "resource2.h"

IDI_MYICON ICON "my_icon.ico"

Ok i am trying to lode the icon "my_icon.ico", but it still has the dumb icon. whats wrong?

While setting all the members of the Window Class, put this:

wc.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_MYICON));

Yes, SyntaxBubble is right. I command you to do as he says.
And here's why he's right:

Lean-mean-programming and design machine. I can do many pro things, but I'm just 14. If you don't like it deal with it. And, yes, I'm taken. If you want to know more about me, <a href="mailto:smokeybear46@hotmail.com">e-mail me</a>. And <a href="http://www.angelfire.com/exreme3/starfield">visit my web site, too.

But that is how you do it? BTW Bubble, who are you taken by?

hmmm that didn't seem to work. does it work different for dev c++?

I use Dev-C++. This is what mine looks like:

wincl.hIcon = LoadIcon(hThisInstance, MAKEINTRESOURCE(500));

In the resource edit I just did:

500 ICON "C:/Dev-C++/Icon/File Management.ico"

I used to have Dev C++ and it worked then. Do you have the right .lib's and .h's?

uh-oh.......lib's?

dunno, if you're using VC++ and when you started off you went to file, new, then under projects went to "Win32 Application", all the libs should be there.

ok then what are the right .lib's and .h's?

no idea - I just let VC++ do all the libs and stuff for me

Tisk tisk tisk, if you are using DirectX or other graphics libs or anything that VC++ doesn't include by default , VC++ doesn't include those libs automaticaly... Trust me, I know from experience.

SyntaxBubble is right: you need to put the full path to your icon file in the resource script for DevC++4. This is an idiosyncrasy of the IDE and not of the underlying compiler, MinGW; it has been rectified in the various Devc++5 beta releases so you can properly use relative paths in those versions.

Generally, to attach an icon to a wnd set the hIcon paramater of the WNDLASSEX structure to the handle of your icon; you can also set the hIconSm parameter if you wish.

Alternatively, after wnd creation you can send a WM_SETICON message to the window, eg:

Code:

SendMessage(hwnd,WM_SETICON,ICON_BIG,(LPARAM)LoadIcon(hInst,MAKEINTRESOURCE(IDI_ICON));

where IDI_ICON is your icon id. This latter technique is also good for dialog boxes.
