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.

I suspect that you are seeing the Icon from explorer's cache. If you are doing this in a post-build event, why don't you link the right icon in to begin with? – Behring

With same dpr I need to create 2 files with 2 names and 2 icons. (of course I could do it with 2 dpr, but this means maintaining both, while this would be perfect solution). ANYWAY YOU ARE RIGHT IT WAS JUST EXPLORER'S CACHE. If yuo post the answer I will accept it. THanks. – Whitted

Downvote seems a bit odd considering that the OP has confirmed that this is the problem!! – Behring

Yeah, it should be explorer's icon cache, the other might be mixed with the browser cache. <g> – Hierophant

@Sertac explorer is not a browser, you are thinking of Internet Explorer! <g> – Behring

yes of course I mean "Windows Explorer". Yes that was the problem I am now able to acheive my goal. – Whitted

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.

I believe you want ie4uinit -show in Windows 10, but ClearIconCache in earlier versions. You can (probably?) just invoke both safely (depending upon your context?). – Noxious
