I am trying to create a custom icon for my application. I have created the ICN#, FREF, BNDL with ResEdit and the new icon comes up fine. Now I find that I need to edit the new icon. I can change it with ResEdit, but nothing I seem to do will persuade the desktop to use the new representation. I've even used ResEdit to look at the application, and it has the new icon in it. "Using the Macintosh Toolbox" from SYBEX says that option-apple-double click on finder forces it to use the new icon, but that doesn't seem to work for me. I am on a Mac II with Finder 6.1, System 6.0.2, Multifinder 6.0.1.

Sometimes it helps to copy your app with the new icon to a blank floppy, rebuild the floppy's desktop with the command-option trick and then copy the application back to your main hard disk. But only on Tuesdays. Pete Helme MacDTS

I'm not sure if this is that great idea, especially on hard disks - sloooow, and I lost once a disk when doing a desktop rebuild from Finder with option-command combination (or is it normal for Finder to take >2 hrs to rebuild the desktop on HD-20 :-?). The simplest solution to Gary's problem that I know of is to: - copy your application to another disk - copy it back If I remember correctly, Finder updates the Desktop file whenever you copy applications. Perhaps even option-drag-to-another-folder will do the job. KK -- Kris Kozminski kk@mcnc.org "The party was a masquerade; the guests were all wearing their faces."

I thought this was common knowledge, but maybe not. Doesn't it always work to do the following? 1. Update the ICN# resource in the application. 2. Make sure the Bundle bit is set. 3. Turn off the Inited bit. <-- the important part At least with System 3.X through 6.0.3, this has always worked for me. I don't use MultiFinder much when I'm programming, though (not enough memory). Does anybody else do this? Does it ever fail? (As far as I can tell, turning off "Inited" tells the Finder it's a file that hasn't been processed yet, so the desktop gets updated.) +----------------------------------+------------------+ | Anton Rang (grad student) | "VMS Forever!" | | University of Wisconsin--Madison | rang@cs.wisc.edu | +----------------------------------+------------------+

Your desktop file needs to be updated before the new icon will appear. One way to do this, as many have suggested, is to rebuild the desktop. Another way (probably not kosher but I do it anyway) is to use ResEdit. Find the old icon in the desktop file, remember its ID, and then replace it with the new one, being careful to set the ID to what it was in the desktop rather than what it was in the application.

Turn off the Inited bit. <-- the important part Sorry, Close but no cigar. You forgot one step. 4. Open the desktop file and look for your application's signature. select it and clear it from the desktop file. Save your changes. I just tried your steps and the finder used the old icon. I guess the finder sees your application, gets its sig, and checks to see if it is in the desktop file, if so it uses the icon in the desktop file. If the desktop file doesn't contain your app's sig, then it looks for it in your app's resource fork and marks it as "inited". Just a theory :-) who knows what the hell the finder does! -- ___________________________________________________________ Matthew Mora SRI International stores@unix.sri.com ___________________________________________________________

Perhaps even option-drag-to-another-folder will do the job. If I remember correctly, the Finder does a desktop file to desktop file copy of all the info related to the application (this includes the icon). However, if it takes too long to re-build your hard disk's desktop file, you can copy the application to a floppy, re-build it's desktop file, and then copy the application back. Hmmm. Now that I think about it though, even this may not be enough. Try it though. ____________________________________________________________________ Have a day. :^| Murat N.

Thanks to all who responded to my request.

The suggestions were:
(1) Copy to a blank disk.
(2) Move to another folder.
(3) Get info for file (in ResEdit) and set Bundle, unset Inited.
(4) Modify the desktop file.
(5) Rebuild the desktop with option-clover Restart.
Only (5) worked. One person warned against this, but I tried it
anyway. On a 60 Meg partition, it only took 1.5 mins. It claims to
have run out of memory in the finder, so perhaps some files lost their
special image.
I would have tried (4), except I have no idea where to find the
desktop file, nor how to modify it.
Again, thanks.
