ScriptCommand Parameter for ltmmWMScript.AddHeaderScript

Value that represents the script command for this header script. This value is the actual script command text and is processed according to the syntax required by the ScriptType value.  There is no built-in command execution in LEADTOOLS Multimedia or Windows Media SDK.  It is up to the multimedia application to determine how to implement script command execution and processing.
 

As an example, for a script type of "url" the application expects the script command to be a fully qualified URL, which should be opened in a browser.
