Using Resource Hacker for changing the icon after the build

Question

This question is written in several places (like here and here).

In the second question there is a comment that says to use

ResHacker.exe -addoverwrite "Project.exe", "Project.exe", "ProgramIcon.ico", ICONGROUP, MAINICON, 0

I also tried using -modify instead of -addoverwrite

ResHacker.exe -modify "Project.exe", "Project.exe", "ProgramIcon.ico", ICONGROUP, MAINICON, 0

but the result is the same.

The icon is changed: if I right click on the exe file and check the properties I see that the icon has been changed, but in Windows Explorer I still see the old icon.

If I open it with Resource Hacker (so not using it as command line tool, but as normal GUI tool) I see the correct icon in the "Open file" dialog.

Can anybody suggest a solution? I am trying to use this in a Delphi post build event.

Answer 1

I suspect that you are seeing the icon from explorer's icon cache.

Answer 2

David's right, Explorer's icon cache needs updating.

Add the following command to your batch file after your ResHacker command:

ie4uinit.exe -ClearIconCache

^{(ie4unit is a built-in command)}

No need to restart explorer.
