I an trying to capture the return error code from running GostScript at the command line, running it using Shell in VBA. The aim is to use it to check that a pdf file is not corrupted and will actually open.
I have around 2,000 pdf files some very old of Genealogical data. If a pdf is corrupted, when trying to open with Adobe Reader it freezes and locks everything up with no way out (except by Ctrl+Alt+Del and stopping the Adobe Reader.
The code I am using is:
pdfShell.Run """C:\Program Files\gs\gs9.07\bin\gswin32c.exe"" -o nul -sDEVICE=nullpage """ & gsPDF & """", 0, True
pdfShell.PopUp Err.Number, 5, "Problem", vbCritical + vbSystemModal
At this point the only error number I get back is 0 (indicating that GhostScript ran successfully) but not any error it generated. When I run in a DOS window I do see the error displayed by GhostScript (doesn't help).
Any assistance or other way of doing it would be appreciated.
