SourceFile Property

Summary

Gets or sets the media source filename, URL or UDP address.

Syntax

C++/CLI

[EditorAttribute(System.Type, System.Type)] 
public virtual string SourceFile { get; set; }

public: 
virtual property String^ SourceFile { 
   String^ get(); 
   void set (    String^ ); 
}

Property Value

A value representing the source filename.

Remarks

This property allows the user to set the media source to the specified filename, URL or UDP address. The SourceType will be set to SourceObjectType.File. The filename can be used to indicate a regular file or a network stream. Assignment can raise an error exception. For more information, refer to the Error Codes.

Note: When trying to rip an audio directly from an audio CD, set the SourceFile property to the location of the file. For example, if the CD-ROM drive is named "F:\" and the ".cda" file for the first track on a CD is called "Track1.cda", then the location of the first track on the CD is "F:\Track01.cda".
