Hi
I'm trying to create application using C and GDI. I want my EXE file to have an ICON, so I created .bmp file (64x64) and added to resource file. Then I created HICON hIcon using that bitmap image (CreateIconIndirect(...))

Now my problem is, .EXE file still has the default windows application icon but when I run it I see the icon (The on I created) in task bar. Now how can I change .EXE icon (Basically add my ICON to the binary file)?

Thanks
Regards
Mark

main.c

wc.lpfnWndProc   = WndProc;
wc.style         = CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS;
wc.cbClsExtra    = 0;
wc.cbWndExtra    = 0;
wc.hInstance     = hInstance;
wc.hIcon         = CreateAppIconFromRes(hInstance); /* **** */
wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
wc.lpszClassName = szAppName;
wc.lpszMenuName  = NULL;
gdi_helper.c

static HICON hAppIcon = NULL;
HICON CreateAppIconFromRes(const HINSTANCE hInst)
{
	HDC hDC;
	HBITMAP hMask, hBitmap;
	ICONINFO iInfo;

	hDC     = CreateCompatibleDC(NULL);
	hMask   = CreateCompatibleBitmap(hDC, 64, 64);
	hBitmap = LoadBitmap(hInst, MAKEINTRESOURCE(IDI_APPICON));

	iInfo.fIcon    = TRUE; /* TRUE for ICON, FALSE for CURSOR */
	iInfo.hbmMask  = hMask;
	iInfo.hbmColor = hBitmap;

	hAppIcon = CreateIconIndirect(&iInfo);

	/* Clean Up */
	DeleteDC(hDC);
	DeleteObject(hMask);
	DeleteObject(hBitmap);

	return hAppIcon;
}
Resource.h

#define IDI_APPICON			3000
sg_resource.rc

#include "resource.h"
#include "afxres.h"

IDI_APPICON		BITMAP		"Data\\ICON.bmp"

Just add a line to your .rc file:

ANY_NAME_FOR_THE_RESOURCE    ICON    "your_icon.ico"

Works for just any app I compile.

Btw, the question you asked has nothing to do with GDI.
