I am trying to extract informations from .exe and .dll files. It works fine, but for some files VerQueryValue function (API) gets the wrong value of language identifier, so I can't extract file description. E.g. for POWERPNT.EXE it gets 0 instead of 1033 (en-us). Is there a chance that language identifier isn't specified in .exe file? How can I get file description in that case? Can anyone tell me what might be the problem and what should I do?

Could you post the code?

I seem to recall we discussed this some.

Thanks, but I am aware of all those things. Still, I know that I can get file description out even if there is no language identifier specified inside the file. First time I call VerQueryValue to get language and code page identifiers, so I could, get file description the second time I call the function, using those values. I have a programme that succedes in getting all of those informations out, so it can be done. I just don't know what to do. Should I go through all language identifiers until I get non-zero value for file description. That doesn't seem like very good solution, but it could work. Help?
