VideoDeviceURL Property

Summary

Gets or sets the video device's URL property.

Syntax

C++

public string VideoDeviceURL { get; set; }

Public Property VideoDeviceURL() As String 
   Get 
   Set

public:  
   property String^ VideoDeviceURL 
   { 
      String^ get() 
      void set(String^ value) 
   }

Property Value

String containing the device's URL property.

Remarks

If the video device does not support an URL property, an error is raised. For more information, refer to the Error Codes.
