I am using your code for my search solution and ran into a little issue when I tried to modify it. I only need to parse PDF and both Office 2003 and 2007 document types. Instead of looking up IFilter in registry by extension, I found what IFilters are used by my local system using IFilter Explorer software, copied DLLs into bin directory of my project and hardcoded Persistent Handler Addin values in my code. Then I matched extensions to DLL location and persistent handler value and extracted content using these hardcoded values. Everything worked perfectly fine till I tried to run the same code on another machine (both machines running Vista). I could no longer extract content on this other machine even though I used the same IFilter DLL files and the same Persistent Handler values. Does Persistent Handler DLL specific or installation/workstation specific? What\'s the difference between \"Persistent Handlers\" and \"Persistent Handlers Addins Registered\" values? I see both of these values in the IFilter Explorer next to DLL name and file extension, but don\'t know what they are used for and how are they different? According to your code, you use \"Persistent Handlers Addins Registered\" value in order to load filter from DLL. I did the same. I\'ve been stuck on this problem for almost a week now and you are my best chance to get it resolve. At least point me in the right direction. All I am trying to do is use the latest IFilter DLLs in my project instead of hoping every machine has the latest IFilter DLL versions for file types that I need. Thanks again for your code and time, Ilia Hey Eyal,

Do you have any idea about it? Hey Eyal, I need to know what all properties(e.g. author,date created) are supported by each IFilter(e.g. .docx,.xlsx) in FIlter Pack 2007.

I'm trying to use your IFilter to extract text from different file types. It work good on word and text. I'm having some problems with the excel files. The text that I receive has the strings in different order. First I receive the text and then the numbers...sounds strange but...And with other implementation of IFilter I get the same thing. With .csv files I get i get the error: “already exists. (Exception from HRESULT: 0×80030050 (STG_E_FILEALREADYEXISTS))”. Any help is appreciated. Thank you! Doru Hi Eyal,

I'm trying to use your posted library to scan a collection of documents. Everything works fine for the first file in the collection, but then on the second file i get an error "already exists. (Exception from HRESULT: 0x80030050 (STG_E_FILEALREADYEXISTS))" do you have any pointers on how to get around this? Thanks! Allan Hi,
