Answered my own question, it appears if I just wrap the arguments in chr(34)’s it will retain the integrity of the argument.
Thanks Emre. -Jason //------------------------------// Jason R. Kretzer Lead Application Developer ja...@gocodigo.com<mailto:ja...@gocodigo.com> //-----------------------------// From: "Jason R.

I do indeed have a static number of arguments. Unfortunately, the reason they are quoted was because the arguments have spaces in them and Wscript.Arguments wants to ignore the quotes :) -Jason //------------------------------// Jason R.

Honestly, I do not have much experience with Vbscript. In your example below, how would I pass arguments to the your_bat.bat? I have 8 quoted arguments that I need to pass the bat file. I have tried this Dim arg0 arg0 = WScript.Arguments.Item(0) WScript.Echo arg0 WshShell.Run chr(34) & "C:\Program Files\yourapp\your_bat.bat" & arg0 & chr(34) , 0 But that is not quite right. It echos the arg0 fine but I get a “The system cannot find the file specified” when I run that. Thoughts? -Jason //------------------------------// Jason R.

What I would like to be able to do is to start a process with a “high” priority. My application spawns multiple processes and I am tinkering with them in order to help ensure they get their processor time. On the command line, I would do this. start /high myspawn.exe arg1 arg2 arg3 Unfortunately one of the requirements is that a DOS window not open to run it. If I start the process like this: QString program = “myspawn.exe"; QStringList arguments; arguments << “arg1” << “arg2" << “arg3"; QProcess *p = new QProcess(this); QTimer::singleShot(30000, this, SLOT(deleteLater())); qDebug() << "starting mysawn process -- " << p->startDetached(program, arguments); It starts just fine, no DOS window, but at Normal priority. I have tried multiple ways using the “start /high…” command inside of the various ways to execute a command with QProcess, but they always flash a DOS window. I even create a .bat file with the command in it and passed arguments in with the above code. While it worked, it flashed the DOS window. Am I missing something here? -Jason //------------------------------// Jason R.
