 === Is there a way to determine the path of currently running script? === === Is there a way to determine the path of currently running script? ===
  
-<del>Yes, the global variable ScriptPortal.Vegas.Script.File contains the full path of the currently executing script. So if your script needs access to a helper file that resides in the same directory, your code might look like this: +Yes, the filename including the complete path is available in the variable sys.argv. In Python sys.argv is a string list containing the script filename and all commandline arguments. The script filename is the first string in the list.
-Language: C#+
  
-String scriptDirectory = Path.GetDirectoryName(ScriptPortal.Vegas.Script.File); +So if your script needs access to a helper file that resides in the same directory, your code might look like this: 
-String helperFile = Path.Combine(scriptDirectory, "HelperFile.ext");</del> + 
-This feature will be provide in the next uopdate of VEGASPython.+<code Python> 
 +clr.AddReference("System.IO") // we need System.IO for Path.GetDirectoryName and Path.Combine 
 +import System.IO 
 +from System.IO import * 
 +import sys 
 +scriptDirectory = Path.GetDirectoryName(sys.argv[0]) 
 +helperFile = Path.Combine(scriptDirectory, "HelperFile.ext")

 +=== How do I start a script from the commandline? === 
 + 
 +Pythonscripts can be started from the commandline together with VEGAS and commandline parameters can be passed to the script. 
 + 
 +Example: 
 +<code> 
 +C:\Program Files\VEGAS\VEGAS Pro 16.0\vegas160.exe /SCRIPTARGS pythonscriptfilename /SCRIPTARGS arg1 /SCRIPTARGS arg2 
 +</code> 
 + 
 +  * pythonscriptfilename: path and filename of the pythonscriptfile to be executed 
 +  * arg1: any text string as argument1 
 +  * arg2: any text string as argument2 
 + 
 +The number of arguments is not limited. 
 + 
 +The first /SCRIPTARGS must be the script filename. 
 + 
 +Example: 
 +<code> 
 +C:\Program Files\VEGAS\VEGAS Pro 16.0\vegas160.exe /SCRIPTARGS "D:\pythonfile\test.py" /SCRIPTARGS arg1 /SCRIPTARGS arg2 
 +</code> 
 + 
 +If the filename or a parameter include blanks, then the parameter must be enclosed in ´""´.  
 +The pythonscript can access the commandline arguments as it is standard in Python via the variable sys.argv. 
 +This variable contains a list of strings with each argument as a separate string item in the list. 
 +The first item is the scriptfilename. 
 + 
 +The python script: 
 + 
 +<code python> 
 +for arg in sys.argv: 
 +    print (arg) 
 +</code> 
 + 
 +gives as output: 
 + 
 +["D:\pythonfile\test.py","arg1","arg2"]

 You can make a custom icon appear for a script you've added to the Scripting menu or toolbar by placing a PNG image in the same folder that contains the script. The PNG file must have the same name as the script with the '.png' extension appended. For example, if the script is named "My Script.cs", the toolbar image should be named "My Script.py.png". The image must be 16 X 16 pixels and must have 32-bit color depth with an alpha channel for transparency. You can make a custom icon appear for a script you've added to the Scripting menu or toolbar by placing a PNG image in the same folder that contains the script.

 You can't. Currently, one major shortcoming of the scripting API in VEGAS is that specific parameters of video effects are not accessible to scripts. The text string of text generators are one such parameter. Scripts can only set presets values for a given key frame. You can't.
