XSIUtils.LaunchProcess

Parameter Type Description

CommandLine String The executable name and any command line options. Be sure to use extra quote characters if there are space characters in any path or filename in the string. For example the quotes in '"C:\My Programs\myeditor.exe"' prevent Softimage from trying to execute an executable named 'C:\My.exe'.

Blocking Boolean If blocking is set to true then Softimage will not return from this method until the child process has finished execution.
Default Value: false

StartupDirectory String An initial directory for the process. When not set the Process will launch with the same directory as the current Softimage working directory. This option is useful when launching command prompts.

Parameter	Type	Description
CommandLine	String	The executable name and any command line options. Be sure to use extra quote characters if there are space characters in any path or filename in the string. For example the quotes in '"C:\My Programs\myeditor.exe"' prevent Softimage from trying to execute an executable named 'C:\My.exe'.
Blocking	Boolean	If blocking is set to true then Softimage will not return from this method until the child process has finished execution. Default Value: false
StartupDirectory	String	An initial directory for the process. When not set the Process will launch with the same directory as the current Softimage working directory. This option is useful when launching command prompts.

1. VBScript Example

'
'	This example launchs a command prompt with the directory set 
'	to the current user path
'
' The new command prompt inherits all the environmental variables
' from Softimage so it will behave like a Softimage command prompt
startDir = Application.InstallationPath( siUserPath )
bBlocking = false 		' We don't want the command prompt to freeze Softimage
if Application.Platform = "Win32" then
	XSIUtils.LaunchProcess "cmd /C start cmd /K title Softimage Command Prompt", bBlocking, startDir  
else
	XSIUtils.LaunchProcess "xterm", bBlocking, startDir
end if

2. JScript Example

/*
	This example shows how the XSIUtils.LaunchProcess method can be used to execute an 
	external process. In this case it shows spdlcheck can be used to test a spdl directly 
	from within scripting.
*/
if ( Application.Platform == "Win32" )
{
	var slash = "\\" ;	
}
else
{
	var slash = "/" ;

var twistSpdl = Application.InstallationPath( siFactoryPath ) + slash + "Application" 
			+ slash + "spdl" + slash + "twistop.spdl" ;

if ( strResults == "" )
{
	LogMessage( "Spdl is OK" ) ;

// Helper function that runs spdlcheck on the provided file path. 
// Returns:
//  - an empty string if the spdl is ok.  
//  - the error details output by spdlcheck if there is a problem.
