问题
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.
回答1:
I suspect that you are seeing the icon from explorer's icon cache.
回答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.
