Writing to the Desktop Database
by Entwicklung 24 Jun '02

24 Jun '02

Hi, I am working on a project where I am required to create a Desktop Database. I have more then 100 files of the same type for which I would like to display the custom icon. I would like to know whether it is possible to display the the custom icon for a file by putting the relevant information in the Desktop Database. How can I set the creator, type, kind and icon data for the custom icon files by writing into the DTDB. Is there a flag called "hasDTDB" present and is it … [View More]

Adding to a Resource Fork of a File programmatically in Windows
by Entwicklung 20 Jun '02

20 Jun '02

Hi, I am working on a Project dealing with HFS and I need some help: Is it possible to display a custom icon for a normal document(not an application) - by writing the resource header, icon-list and resource map in the file's resource fork. If possible how do I do it in Windows(not in Mac)? What is the structure of a resource fork? How do I programmatically insert the resources into a file in Windows, so that the Icon resource is visible when viewed in a Mac. Entwicklung.

Problem faced :: Till now I used to find the total volume size first since i knew the size of each file. And then as in the Linux … [View More]

Re: hfsutils
by Entwicklung 08 May '02

Hi, Thanks for the reply. The problem is that I don't have any medium(disk) for such large images. I'm using Linux on an Intel PC and hfsutils since I can also specify a path to a directory. Upto 650MB I was using a normal CD. Manual mounting gives me the error 'not a block device' if I specify the path to the image. I also have no clue as to how I could write my image to a hard-disk perhaps starting at physical block 0. Maybe after that a manual mount would be possible.(?) But I guess … [View More]

hfsutils
by Entwicklung 07 May '02

07 May '02

Hello, I'd like to know if anyone who has used hfsutils in the past knows upto what allocation block size it supports for reading. I have an allocation block size of 64kB and I'm unable to mount my hfs-volume. It is slightly larger than 2GB in size. Images of size 32MB, 64MB upto 512MB, 1GB and < 2GB seem to work fine. I get the following error : Sorry, unable to mount volume. Read unallocated block (Input/Output error). Does anybody know if hfsutils imposes a restriction on … [View More]

Wrapper and Readme
by Entwicklung 07 May '02

07 May '02

Hello Listers, Thanks to the friendly feedback I got I managed to get started off with including an HFS-Wrapper in my code. It seems to work ok now but I'm not too sure... I only have access to an iMac with MacOS 9 - my HFS+ Volume gets displayed but how do I get to verify if the ReadMe I'm creating in the Wrapper is ok ? The volume is recognized as an HFS+ Volume (since the embedded volume seems to be getting mounted directly) and I can do a GetInfo on it. Do I … [View More]

Unwrapped HFS+ volumes
by Gordon Beatty 06 May '02

06 May '02

Hi all, Since people have asked questions about wrapped HFS+ volumes, I was reminded of a question I'd been meaning to ask. In general, by default, HFS+ volumes are created with the HFS wrapper for compatibility and are coded in the Partition Map with a type of 'Apple_HFS'. However, the potential exists for HFS+ volumes to exist on their own without the wrapper (especially where OS X is concerned -- or so I am led to believe). My question is simply, would such an unwrapped volume be coded … [View More]
