My windows co-workers were asking me if I could modify my non-windows binary files such that when their "Properties" are examined under Windows, they could see a "Version" tab like that which would show for a Visual Studio compiled exe.
Specifically, I have some gzipped binary files and was wondering if I could modify them to satisfy this demand. If there's a better way, that would be fine, too.
Is there a way I could make my binaries appear to be exe files?
I tried simply appending the VS_VERSION_INFO block from notepad.exe to the end of one of my binaries in the hope that Windows scans for the block, but it didn't work.
I tried editing the other information regarding Author, Subject, Revision, etc. That doesn't modify the file, it just creates another data fork(what's the windows term?) for the file in NTFS.
It is not supported by windows, since each file type has their own file format. But that doesn't mean you can't accomplish it. The resources stored inside dlls and exes are part of the file format.
Display to the user:
If you wanted this information to be displayed to the user, this would probably be best accomplished with using a property page shell extension. You would create a similar looking page, but it wouldn't be using the exact same page. There is a really good multi part tutorial on shell extensions, including property pages starting with that link.
Where to actually store the resource:
Instead of appending a block to the file, you could store the resource into a separate alternate data stream on the same file. This would leave the original file stream non corrupted on disk and not cause its primary file size to change.
Alternate data streams allow more than one data stream to be associated with a filename. Each stream is identified by a colon : at the end of the filename and an identifier.
You can create them for example by doing:
notepad test.txt:adsname1
notepad test.txt:adsname2
notepad test.txt
Getting the normal Win32 APIs working:
If you wanted the normal API to work, you'd have to intercept the Win32 APIs: LoadLibraryEx, FindResource, LoadResource and LockResource. This is probably not worth the trouble though since you are already creating your own property page.
Can't think of any way to do this short of a shell extension. The approach I've taken in the past is a separate "census" program that knows how to read version information from any kind of file.
Zip files can be converted into exe files by using a program that turns a zip file into a self-extracting zip (I know that WinZip does this, there are most likely free utilities for this also; here's one that came up on a search but I haven't actually tried it). Once you've got an exe, you should be able to use a tool like Resource Hacker to change the version information.
It won't work. Either Windows would have to know every file format or no file format would be disturbed if version information were appended to it.
No, resource section is only expected inside PE (portable executable; exe, dll, sys).
It is more then just putting the data inside the file, you have a table that points to the data in the file header.
What you can do if you have NTFS drive, is to use NTFS stream to store custom properties this way the contact of the binary file will remain the same, but you will need to use a custom shell extension to show the content of the stream.

I have a folder which contains an executable file (Exec.exe) and a lot of files that Exec.exe needs to run. Currently, it's pretty ugly having all of those files there when I only need to run the one executable. Is there any way to bundle them all into another executable that runs Exec.exe and also contains all of the files Exec.exe needs to run? Thanks for any help!
Yes, but I would recommend you only do it if you need to.
You can achieve this by adding your files as resources in your exe project, so they are added into the exe's binary at compile time. You can then access the files directly from your exe at runtime by using LoadResource and related functions. I'd recommend reading up on the Portable Executable (PE) file format if you're considering this route.
This is the way to do it if you, and again I stress, need to have only a single binary where you can still access your files. There are obvious downsides to doing this, such as it's much more coding to access the data as it's embedded in your application binary, and you can't easily update the files (check out resource hacker tool) without re-compiling your binary to include the new data.
If the only reason you want to do this is because it's "pretty ugly" seeing the additional files in the same directory as your exe, consider moving them into another directory, for example,
from:
MyExeDir
--myExe.exe
--myFile1.txt
--myFile2.dll
--myFile3.dat
to:
MyExeDir
--myExe.exe
--dat
----myFile1.txt
----myFile2.png
----myFile3.dat
or:
MyExeDir
--bin
----myExe.exe
--dat
----myFile1.txt
----myFile2.png
----myFile3.dat
So all the "ugly" looking files are out of the way.
Why don't you create a shortcut of "Exec.exe" and keep it somewhere handy ? If whats that you want ?
Or if you want to distribute your app, you can use Winrar/Winzip (winrar is the best) to create a compressed .exe of your entire folder, making "Exec.exe" as your startup app. Use the SFX option in winrar.
For an application I would like to store a collection of files together, and have them appear in the filesystem as a single file so its easy to manage. I am currently storing everything in a folder.
I would like to keep things accessible so you can manually edit the inside contents if neccesary.
One way to do this would be to create a zip archive and give it a custom extension other then .zip. Then it appears as a filetype and if needed you can unpack and access the content, but for normal use keep it hidden.
I can't seem to find a convenient way to do this. Boost and zlib can do the compression but don't work with archives. I found libzip but I have a hard time understanding how to use it and to me it seems that it only reads/writes zip archives without doing the actual compression.
Is there a more convenient way to tackle this?
Can you call system functions for creating an archive on OSX from c++ / Carbon?
Is there another way to make a folder appear as a single file?
In OSX, you can create Document Packages (similar to application bundles) which are treated as a single file in the Finder, but are really just directories with some internal structure.
Apple does not zip these packages, but they do provide the functionality you describe and they can be created and accessed through CoreFoundation by using CFBundleRef .
From the documentation:
... The important thing to remember about creating a document package is that it is just a directory. As long as the type of the document package is registered (as described in “Registering Your Document Type”), all you have to do is create a directory with the appropriate filename extension. (The Finder uses the filename extension as its cue to treat the directory as a package.) You can create the directory (and create any files you want to put inside that directory) using the standard BSD file system routines ...
As 1st step, simple rename the folder and add the extension .bundle, e.g. Myappdir.bundle
That's will show the whole folder as one file with a lego-like bundle icon.
The next step is you must create one Info.plist file inside.
I've developed a GUI for some build scripts, and am now in the process of deploying it. As the script will be deployed to a number of different machines at various points, I need to use the standard format of directories that the team use.
The GUI consists of a ".fig" file that contains the visual definition of the UI, and a m-script that defines the functionality. I need to locate these two in "fig/" and "m/" folders respectively, but I can't figure out how to. I first searched for an include statement of some kind in the m-script, as when I Run it on its own, the error message in the command window states that the ".fig" file can't be found, but there doesn't seem to be a reference to the ".fig" file anywhere, I assume that it's inferred as both files have the same name but a different extension.
I fear that Matlab's GUI system requires that both ".m" and ".fig" files are in the same location, but this will be an inelegant solution that I'd rather not go for if I can avoid it.
The next thing I'm going to try is to call a script that copies the fig file from the other directory to the same location as the m-script, when it is executed, then deletes that copy once the script exits, which again seems a clunky solution, but will allow me to adhere to the team's organisation conventions.
Does anyone else know of an undocumented means of specifying the relative location of a GUI ".fig" file?
You can export the GUIDE-generated GUI as a single .m file. Check out this blog post: GUIDE GUIs in All One File.
I'm not sure if this is a new feature, or one of those things that has always been there...
I need to be able edit the content of index.dat file programmatically (C:\Documents and Settings\Username\Cookies\index.dat). More precisely I need to modify it in order that index.dat for one user can be used for a different user name. Is there any documentation out there for this kind of binary file?
Pasco (http://www.foundstone.com/us/resources/proddesc/pasco.htm) is a free index.dat parser that comes with the source code.
Docs will be hard to come by - Microsoft has never publicly documented the structure of the the structure of this file. That said, you can find docs on the web such as the one mentioned above.
However, note that IE keeps close tabs on this file. The file is locked while IE is running (meaning, you can open/read it in some modes but not in others) and you can certainly not write to it.
One method that might still work is to boot-up in safe mode and then assign yourself administrator rights and then see if you can find the files to delete them.
The method I now use is to create a batch file to rename the subfolder below the folder containing the index.bat files and to then only copy the folders back to the original location that don't contain these files but the resultant batch files needs to be run from a separate windows account that has full administrator permissions.
The freeware code editor PSPad will allow you to view and to edit the contents of all of the index.dat files on your computer in hexadecimal form. This is done by replacing all of the digits in the first eight columns with zeros. This removes all of the information contained in the files.
It's a tedious process, requiring holding down the "0" (zero numeric key) as all of the edits are made, but anyone then accessing any of the index.dat files will get no information.
IE must be closed when doing this or you may receive an error message when attempting to save the modified file(s).
What I need is a directory which the user can handle as a single file in the Windows explorer. Does something like this exist? If not, what comes closest?
The closest thing is probably Alternate Data Streams, although those are more akin to MacOS Named Forks than Bundles.
There are also some special cases, for example if you save a website with Internet Explorer you get an HTML file and a folder which are linked together.
Depends on your particular needs. As mentioned above, named streams are possible (on NTFS), however you should notice that not all applications copy files with named streams correctly. In some scenarios regular ZIP archives can work (Explorer shows them as folders). If you are doing software development, there exist libraries that let you store many files in one container file (eg. SolFS).
I think you can create a folder with an extension, e.g. Myfolder.bundle, then you can associate that extension with a custom icon. So it looks like a bundle as far as the end user is concerned.
