Member 11358539 15-Jan-15 6:36 15-Jan-15 6:36 Hi, great job on this piece of code by the way this saved me a lot of work in writing this myself from scratch. I was wondering, if it would be simple enough to extract the IconLabel value and use this as the file name when extracting from Word? Metz Sca 3101 M3 Manual on this page. Basically, I need to relate the document I have extracted back to the position I found it in the report. Most of the time, the documents seem to get extracted in the order that they are found embedded in the document but this does not always seem to be the case.
Ildasm.exe takes a portable executable (PE) file. Starting with the Net. You cannot use this technique with PE files that contain embedded native code. Launch eMbedded Visual C++ 4.0. On the File menu, click New. Building XML Web Services for Windows CE.NET using native code is fast and simple.
Hmm I tested this when I first set it up, and I found moving the embedding position and saving did seem to reorder the documents in the pool. Although, this is clearly not happening in the current document I am working on. I am specifically trying to extract PDF documents, and I need to be able to relate the extracted document to the position it is in the word document. I have spent all of this morning reading the Compound File format spec and I cannot find any reference to the icon label (in the word api, you can get the icon label of a selected PDF by using?Selection.InlineShapes(1).OLEFormat.IconLabel), I also can't seem to find how the EMBED field relates to the object in the ObjectPool.
Ok so I think I have got my head round this now, they seem to be sorted in order of the OleObject Name. Download 520 Ability Interval Interval Manual Running Sports Training Workout. The reason this is going out of order is I have 11 embedded PDFs in my document and the object names are going up to OleObject11. The number after the OleObject does relate to the position that those objects appear in the document text. The sort is ending up like this: OleObject1 -->EmbeddedObject OleObject10 -->EmbeddedObject1 OleObject11 -->EmbeddedObject2 OleObject2 -->EmbeddedObject3 They do seem to be reordered in the document if you move the position and save. So I am using something like result.Add(ExtractFromStorageNode(compoundFile.RootStorage, outputFolder, Path.GetFileNameWithoutExtension(packagePart.Uri.OriginalString) )); To get the package part name.
I am thinking this might only work on the 2007+ documents though. Thank you Kees, for the purposes I am using this for I think extracting the files based on their 'oleObject' name is going to satisfy my requirements for now - and I needed to get a fix out by the end of today so that has solved my current issue. Although, like I said I think this probably only works for OOXML documents. I don't necessarily need the icon text, just need to be able to relate the position the Icon is found in the document to the EmbeddedObject that is extracted.
My software basically converts the word document to PDF but it expands all embedded PDFs into the document and scales them down to fit on the page. It's pretty easy to match this back when working with OOXML documents as the relationshipId from the shape maps quite easily to the files _embeddedFiles folder, but it seems a lot more difficult when it comes to the binary format.

MS compound document formats are horrible as the developers of POI learned, and that is why open source POI (and.NET NPOI) name their document parsers the following: - HSSF =>Horrible Spreadsheet Format - HWPF =>Horrible Word Processing Format etc. POI itself stands for Poor Obfuscation Implementation. Those developers have a sense of humor.
I was working with PowerPoint embedded document extraction last week for use in a massively parallel document ingestion prototype. I used OpenMCDF for the compound document parsing. I see you embedded OpenMCDF library which has a Mozilla license [] along with your extractor class in the same project. This might make the your code also MPL license and not CPOL. You might want to separate concerns and just link to the OpenMcdf assembly.
Regards, Tony Jenniges. Hi, You had a good point about the license, I removed the OpenMCDF code and put it in a new nuget package called CompoundFileStorage. The reason why I didn't use the original OpenMCDF package is because it was written for C#.NET 2.0 and it was a little bit messy code (but still very good code). I upgraded the code to more now a days standards and used things that are only available in.NET 4.0.

Assemblies are not 'real' executables, they are Intermediate Language which has a lot of resemblance to assembly language. When you build your project, you're really building to IL. You can look at this with an assembly viewer like ILDASM, the Microsoft IL Disassembler 2. The IL is hardware and machine independant because the JIT compiler is hardware and machine specific, that is, it compiles the IL down to a 'real' executable format.
