I have recently bought a program to help me merge pdf files (thanks to some EE help).  I am now faced with another situation.  I am sure this is an easy question, but I am at my witts end.  

I want to send the command via the command line.  The only instructions that I am given are the following:

To perform batch conversion or call conversion procedure from an automation script, you can use command line function in the PDF Split-Merge software, You can either run this tool directly from command line or call it from any script as well. The program supports the following command-line options:

PDF Split/Merge software v1.0
Copyright @2003-2004 www.verypdf.com Inc
arguments: file1 [file2 ...] destfile
arguments: burst C:\input.pdf C:\output
Example:
pdfpg C:\A.pdf,1,3 C:\merged.pdf
pdfpg C:\A.pdf,-20,50 C:\merged.pdf
pdfpg C:\A.pdf,1,3- C:\merged.pdf
pdfpg C:\A.pdf,1,2,3 C:\B.pdf,5,2,9 C:\merged.pdf
pdfpg C:\A.pdf,1,1-9 C:\B.pdf,5,2,9 C:\A.pdf,10 C:\merged.pdf
pdfpg burst C:\A.pdf C:\split



My question is...how do I access the command line?  I have tried several things, but to no avail.  Please let me know if you need further information from me to help me get this accomplished and of course I am pressed for time on this.

Thanks, J

ARe you trying to run this from within an ASP page? To run command-line options, you need to use WScriptShell or ASPExec--however, I think that these command lines you refer are supposed to be entered directly into the Split/Merge software program

I am trying to run this from within the ASP page.  I am working on getting it to run with the shell command.  According to the little directions that I was given, in a perfect world a developer should be able to combine the documents on the back end.

Right now I have:

Dim WshShell
Set WshShell = Server.CreateObject("WScript.Shell")
WshShell.Run  "C:\PDFSM\pdfpg c:\docs\a.pdf c:\docs\b.pdf c:\merged.pdf"
Set WshShell = Nothing

PDFSM being the folder I installed the software in.
but it doesnt seem to be working

To run the command line in ASP, try:

<html>
<body>
<Script language=vbscript runat="server">
    Dim objShell
Set objShell= CreateObject ("WSCript.shell")
objShell.run  "cmd /K CD C:\temp & pdftohtml.exe a.pdf & exit"
Set objShell= Nothing
     
</script>
</body>
</html>

Or try using the free ASPEXEC near the bottom of this page:

The next thing that you need to do is to give the IUSR_ and IWAM_ accounts READ/WRITE permissions to all of the directories where you will be working with your .pdf files.

nope, that is what is bugging me.  It acts like it is running correctly, but it is not creating the file.

Okay, I am surprised that you aren't getting a permisssions error, but that is most likely what is happening here.

I would consider putting all of the .pdf files in the subdirectory of PDFSM like this:

C:\PDFSM\Source
C:\PDFSM\Merged

and then give liberal permissions to the PDFSM directory and the subdirectories.

ok, now i have full permissions on the folder for everyone and I am getting a permission denied.

I will play around with it.  Thanks for all of your help.  If you were to think of anything else, please let me know.

Sure--keep in mind that the IUSR account may not be part of the everybody group for security reasons, so it is important to set that separately. Also, try running a simple .bat file to get that working first so that you know you have the permissions set correctly.

Good luck,
