Loading an icon from a file (Win32)

Loading an icon from a file (Win32)

I’m always perturbed by how difficult it is to load an icon in Win32 at times.  So many HICON/HANDLE and whatnot special data members and folks on forums doing strange stuff.  Here’s a snippet of code that just loads a simple icon file and displays it as your executable icon.  I’m sure there is a more correct/newer/snazzier way to do this – but this works fine for me…

LPCTSTR iconPathName= L"../MyIcon.ico";
HANDLE hIcon = LoadImage(hInstance, iconPathName, IMAGE_ICON, 0, 0, icon_flags);

// set up RegisterClass struct
wcex.style            = CS_OWNDC | CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc    = WndProc;
wcex.cbClsExtra        = 0;
wcex.cbWndExtra        = 0;
wcex.hInstance        = hInstance;
wcex.hIcon            = (HICON) hIcon;
wcex.hCursor        = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground    = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName    = NULL;
wcex.lpszClassName    = m_AppTitle.c_str();

// register the window class
return RegisterClassEx(&wcex);
