    startfile problems

    hello i have a very odd issue with os.startfile()

    ok basicly my app works perfectly on every single other pc todate. i
    cannot recreate this issue on any system. so i've already ruled out any
    obvious coding issues, such as wrong file names etc. this issue only
    occurs on this one old pc.

    upon trying to os.startfile() a pdf document (that i create) i get the
    error - Windows error [erro2]"System cannot find the specified file"
    however when i go in to the program directory, the file is there, and i
    can open it. i have ruled out the following:
    the pdf viewer is working.
    the path and file name are correct
    the path and file name do not contain any spaces and what not.

    it's a windows xp system and i'm using python 2.3

    i'm very curious as to what everyone thinks

      I suspect most of us think: Where's the code?
      followed by: Where's the traceback?

      As for your statement of verifying the path and filename... We
      haven't seen it so can't guess... (part of the "where's the code")

      Does the path contain \n, \t, \r, \f, etc. If it does, and you
      are not using a raw string, you are looking for a file with newline,
      tab, carriage return, formfeed, etc. respectively in the name.


      fid = "c:\temp\someth ing.pdf" #bad, this is
      # c:<tab>emp\some thing.pdf
      # assuming \s isn't some special character

      fid = r"c:\temp\somet hing.pdf" #good
      fid = "c:\\temp\\some thing.pds" #okay

          it's iterally just

          PDFname = 'tmp.pdf'
          os.startfile(PD Fname)

          thats the code.

          so obviously it contains no errnous characters. see my update btw. it
          actually DOES open the report, but throws up the exception as well.

              No "import os"?
              And the full traceback?

              Must not have made it to my server yet, assuming it was posted
              after my comment.

              import os

              PDFname = "test.pdf"
              os.startfile(PD Fname)

              No errors if I'm in the directory with the PDF when I execute
              the program...

                  yep the program is executed in the same dir as the pdf file. like i said
                  it actually opens it, but throws up an exception as well.
                  if i hadn't seen it with my own eyes i wouldn't believe it.

                      You are far more likely to get informed help if you post the traceback
                      here, as has been suggested twice already.

                          i can't since it's a remote site and i can't reproduce the error. the
                          best i have is a screen shot.
                          besdies which the only information it gives is the names and line
                          numbers of the my py modules, nothing more. the only real info it gives
                          i have posted already, in my inital post (the last line of it,
                          WindowsError etc..)

                          other then that there's no more information to be had. it's a bloody
                          simple 2 line function, nothing funky about it.
