Hi Chesong, Thanks
for the info. Some more testing – the problem does occur with Server 2003
also. I had to replicate the pattern on XP once more to see it happening there
so I think this looks like a more general problem. However, I can say that the
same thing happens with ARPPRODUCTICON on XP – no matter which icon I
specify, the first one is in use. Server 2003 does update modifications to this
property. I don’t think there are workarounds for this – just stick
to one ARPICON and not modify it at RTM. Once
again, thanks for the info. Best regards, Calin From:

Lee We
have encountered the same problem. Windows Explorer is the culprit, not MSI
engine. Explorer does not invalidate its icon cache even if the icon file is
changed, at least in Windows XP. Refreshing
icon cache can be a solution using a custom action. Although there is no known
public API to refresh the shell icon cache, there is a way by changing the
shell icon size (e.g. +1 or -1 of the existing value) and restoring to the old
value. But this solution has a side effect that user’s desktop icons are
rearranged. When we shipped with such custom action, we got some complaints
from customers for the side effect. So we decided not to use this technique. Another
solution for us was the same solution you are using – changing the icon
name whenever the icon data is changed – we add a suffix using MD5 hash
of the icon file – we do this way because we supply several OEM versions
of the package with custom icons and there should be an automated way to change
the icon name. So
far that is the only feasible way to circumvent icon cache problems for me. FYI: To
achieve this, we implemented in two ways:
First
one is easier to implement. Second is more convenient to use but it has a
subtle side-effect that MSI file size grows a little bit for updating rows
containing binary columns (OLE storage limitation, mentioned in MSDN). So the
first one is the one we use at this time. Regards, Chesong

[mailto:[EMAIL PROTECTED] On Behalf Of Calin Iaru Hi List,
Strange thing on Windows XP – maybe you can tell me more about it. If I
create a shortcut and specify an Icon, then that initial icon is displayed no
matter if the icon - as a binary file - has been modified and the MSI
recompiled. This is not the case with Server 2003, where the icons are properly
displayed. So far it seems that changing the icon Id whenever an update on that
binary is made makes XP happy. Best regards,
Calin |
