Thanks for the link, but... I tried the following from within a .bat file: start /wait cmd /C "C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" -browser -url "file:///C:/Users/DES/Documents/MSData/HTML/GPD.shtml"

I also tried just: start /wait cmd /C "C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" -url "file:///C:/Users/DES/Documents/MSData/HTML/GPD.shtml"

In neither case did Firefox start, at all. Without "any" parameters, it will start up just fine, but I want to start up with the page that I am passing it.

As an FYI my initial attempt was: start /wait cmd /C "C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" "file:///C:/Users/DES/Documents/MSData/HTML/GPD.shtml"

Sorry, I am fuzzy when it comes to batch files in Windows, but for the Firefox part of it try this.

"C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" -browser "file://///C:/Users/DES/Documents/MSData/HTML/GPD.shtml"

or

"C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" -browser -url "file://///C:/Users/DES/Documents/MSData/HTML/GPD.shtml"

When I change the .bat file to "C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" -browser -url "file:///C:/Users/DES/Documents/MSData/HTML/GPD.shtml" (with only 3 leading slashes) it works. I really want to preface the program name with the Windows command: start /wait cmd /C , which starts the program and waits for its completion before processing further commands in the .bat file. The Help on that DOS command states that parameters can follow the program/command name without any "switches".

This should work in a .cmd or .bat file.

start "" "C:\Program Files (x86)\Mozilla Firefox\Firefox.exe" "C:\Users\DES\Documents\MSData\HTML\GPD.shtml"

Thanks! I don't know where I came up with the /C switch. The /wait switch does work. It does need the "file:///" preceding the file name, though.
