As to other icon sizes as Peter mentions you can use multi-page icons that hold all the different sizes you may need in a single icon file. Lots of tools let you create these multi-size icons.

>>I am using ResHacker.exe to add the mainicon to the VFP exe. Now I like to add more icon resources to the same executable, but I did not find any reference in the help how to do it. I played with the parameters like MAINICON and the last parameter set to 1 etc, but nothing seems to work. It would either show the one or the other icon and no clear way how to enumerate both (getting a specific icon based on the ID).

The Reshacker was used already since Windows XP when there have been problems with icon resources in VFP. I remember vaguely that the icon file set as project icon was not always compatible with the Windows icon resource and when creating a shortcut on the desktop it would show the default VFP icon instead of the custom icon. I think it had something to do with the colors used in the icons. Not sure if that was pre-Service Pack 2 or if that was solved in Windows, but I let the code in our project builder for the last 10 years and never touched it.

My idea was to change the icon in the Windows taskbar during a long calculation into another icon using Sendmessage() and using the icon resource from the executable. I am not sure if I can use SendMessage when the icon is a physical file or just a file embedded in the exe, but the original code I got was using Extracticon which would use the ID of the icon resource.

Since the calculation can take several minutes, I am trying to show this in the taskbar, so the user can do other productive work without the need to check the program constantly to see if the calculation is finished.
