Running EXEs from JScript in XSI

To run programs from JScript, you can use XSIUtils.LaunchProcess.

Here’s a simple example that does a dir on C:\Program Files, redirects the output to a text file, and then uses Notepad to open the text file:

var sPath = XSIUtils.Environment("TEMP");
XSIUtils.LaunchProcess( 'cmd /C "dir > ' + sPath + '\\dir222.txt"', false, "C:\\Program Files" );
XSIUtils.LaunchProcess( 'notepad ' + sPath + '\\dir222.txt', false, "C:\\" );

The third argument to LaunchProcess will be the current working directory of the launched process. So in the above example, I’m doing a dir of C:\Program Files (because cmd opens with C:\Program Files as its current directory).

If the exe is not in the system PATH, then you need to specify the full location:

var sCommandLine = "C:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\Common7\\IDE\\devenv.exe";
var sStartupDirectory = Application.InstallationPath( siWorkgroupPath );
XSIUtils.LaunchProcess( sCommandLine, false, sStartupDirectory );

In the above example, I’m using my workgroup location as the current directory, so when I do File > Open in Visual Studio, by default I will be looking in my workgroup location.

    • Sure

      from win32com.client import Dispatch as disp
      siut = disp(‘XSI.Utils’)

      sPath = siut.Environment(“TEMP”)
      siut.LaunchProcess( ‘cmd /C “dir > ‘ + sPath + ‘\\dirTest.txt”‘, False, “C:\\Program Files” )
      siut.LaunchProcess( ‘notepad ‘ + sPath + ‘\\dirTest.txt’, False, “C:\\” )

      With Python, you can also run EXEs like this:

      import subprocess
      subprocess.Popen( “notepad.exe”, False )

      or this:

      import subprocess as sp

      run = [r’C:\Windows\System32\PING.EXE’]
      args = r’-n 50’


  1. thank you, I will give tihs a try.
    I want to launch a “xsibatch -script” from a toolbar to process some scripts on a Model, without interferring with my actual scene.
