Need help in creating a vb script

Hi,

I'm having a requirement that, files are generating to a shared drive but we are unable to access the files in the folder. So I'm thinking that while generating the PDF only I want to give the permissions also. Below is the sample code:

RT=objshell.run("E:\AppendPDF.bat" & " " & parm1 & " " & parm2 & " " & parm3 & " " &  parm4, 0, TRUE)

Using AppendPDF.bat the individual PDF files will be merged into a single file. After merging the PDF we are unable to view the file.
