I there was the correct way of doing this on this form. I probably should write a blog to centralize the information.

 Ripped from an old thread I posted in ... back when I too pondered over the horrors of changing my applications icon.

What a painful experience. For anyone who is looking to do the same you need to follow this process:

• In Solution Explorer find the "Resource Files" folder (if you work in "Show all files" mode like I do you may need to switch to see the folder)
• Right click "Resource Files" folder and select Add > Resource...
• From the window dialog select "Icon" and choose "Import" (your icon must be .ico format)

With those steps complete, head over to wherever you have created your window and add the following code:

// Get device context
HWND hwnd = m_Window->GetHandle();
HDC hdc = GetDC(hwnd);
	
// Load the icon for window titlebar and taskbar
HICON icon = LoadIconA(GetModuleHandle(NULL), (LPCSTR)IDI_ICON1);
SendMessage(hwnd, WM_SETICON, ICON_SMALL, reinterpret_cast<LPARAM>(icon));

I would recommend to clean up your projects directory by added a "res" folder and dragging in the files that were created when you added a resource to your project.

P.S. It should go without saying but whatever variable name you have provided for your window (mine is m_Window) replace that with your own.

All jokes aside it wasn't that difficult, the worst part was trawling through the Win32 API reference and hitting dozens of deprecated pages. @reepblue looking forward to the blog post  ?

I believe that's the exact soultion I used. Sorry I never did a blog post about it.
