VideoDeviceURL Property

Summary

Gets or sets the video device's URL property.

Syntax

C++/CLI

public string VideoDeviceURL { 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.
