During the last couple of days I have done a lot of experiments with this software and studied a lot more about compound files. The example noted above is in a number of cases of "example code"in the (otherwise very good) HelpFile and it simply doesn't work. By studying the use of delegates and Action in C# I was finally able to correct the code so that it works: I changed the reference to "VisitedEntryAction" to be a simple System.Action, so...: Action va = delegate (CFItem item) { CFi.Add(item);...

As far as I know, there is no actual count of images in the FIB. (But it is a complex variable block and I may have missed something...) I think your best bet would be to use the information here: https://msdn.microsoft.com/en-us/library/office/hh965732(v=office.14).aspx ...and detect each image, counting as you go. HTH, Pete.

I am very new to OLE Structured Storage but I managed to download your OpenMCDF and install the package thru NuGet. (Into VS2015) What I need to do is pretty simple and falls into 3 steps: Open an existing OSS file (I'll call it "the archive") and get a list of the Storage and Streams it contains. Extract certain selected streams, Edit them. (They are actually plain text files...) Replace the edited streams in the archive. (Or, if this is too dificult, create a new archive and write all of the storage...

I had exactly the same problem. Right Clicking Properties did not show any "unblock" button. Solved it by Extracting the OpenMCDF download Zip into a new directory, and clicking on the extracted .chm file in the new directory. Pete.

Thanks Igor. I have done the homework using the pointers you gave and I believe I can solve this now. Congratulations on 7-Zip; it is an excellent package.

Thank you very much for this information. I never heard of this Compound Document File Format but I'll spend some time on the web and try to get a handle on it. I did download 7-FAR from the link you kindly provided but I'm not sure what to do with it... :-) Is there a way I can call the FAR plugin from C#? (Maybe a wrapper of some kind...?) I need to do the in situ update from my own code and not from a browser. The first article I read on Compound documents seemed to suggest that they are COM compliant...

unfortunately the snip of the listing has been mangled out of sight... here's another attempt: Listing archive: ContaFin.ppj -- Path = ContaFin.ppj Type = Compound Physical Size = 1561088 Extension = compound Cluster Size = 512 Sector Size = 64 Date Time Attr Size Compressed Name ------------------- ----- ------------ ------------ ------------------------ ..... 2047 2048 $Recipe 2017-11-27 21:59:15 D....

7-Zip [64] 9.6 Beta Windows 8.1 (64 bit) I have a PowerCOBOL project file (.PPJ) that is opened by 7z without any problem at all. In fact, 7z is the ONLY software I have found (apart from the PowerCOBOL.exe) that can open this archive. I tried DotNetZip, WinZip, and System.IO.Compression libray with C# and none of them could read it. I can extract the archive files without problem, I can add them to a new archive, but I cannot update them in situ. (The new archive is no use because it is not recognized...
