change application icon

[Paolo]

Hello,

I have successfully converted from Deplhi some app of mine, however the icon is still the delphi one, whatever I try in project option.

any suggestion ?

win-10/laz 4.2.

Thanks

to be more precise : on windows view with small icon i see picture 1 with greater icon  greater I see picture 2

delete the res and do a build.

already tried.. nothing.

now the problem is disappeared, maybe a refresh problem of windows ???? (even if for sure I deleted the folder and pressed F5 several times).

The problem is Windows, which caches the icon. For me (and not only in Delphi) the icon sometimes stays the same for hours (and if I move the .exe to a virtual machine, the icon is correct).

Now it doesn't bother me anymore; I know the icon is correct.

Ok, it seems the case.

Other file managers may also do their own icon caching, for example Total Commander.

Windows caches icons in your user profile. You can delete these

%userprofile%\AppData\Local\Microsoft\Windows\Explorer\iconcache_*.db

You will need to reboot afterwards. Even then this is not a 100% solution, there may be file type associations or your theme/icon pack which override the icons.

What a mess.

Simpler (Windows only):

Code: Pascal  [Select][+][-]

1. program refreshiconcache;
2. uses windows,shellapi;
3.  
4. procedure RefreshIcons;  
5. begin
6.     // Notify shell that file associations have changed
7.     SHChangeNotify(
8.         SHCNE_ASSOCCHANGED,  // Event: associations changed
9.         SHCNF_IDLIST,        // No path needed
10.         nil,
11.         nil
12.     );
13. end;
14.  
15. begin
16.   RefreshIcons;
17. end.

Full program, handy function...
This forces the shell to reload the icons.
