I need to modify the image inside of an ICO file, but when I edit it in Visual Studio, the file appears unchanged. I edit the file and get it the way I want it, then save it. When I re-open it, it looks just like I want it, but it appears unchanged in Windows Explorer, when I have it displayed as a Thumbnail. And when I use the ICO file on a button, it is shown the old way. What an I doing wrong?
Anybody know what the trick is to getting Windows and Visual Studio to recognize the change?
