IsRoleSelect Method

Summary

Determines whether Role Selection is enabled for the specified Presentation Context of the DICOM Associate.

Syntax
C#
VB
C++
public bool IsRoleSelect( 
   byte id 
) 
Public Function IsRoleSelect( _ 
   ByVal id As Byte _ 
) As Boolean 
public: 
bool IsRoleSelect(  
   byte id 
)  

Parameters

id
Presentation Context ID of the Presentation Context for which to check Role Selection. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data. It also identifies a specific Presentation Context within an Associate.

Return Value

true if the Role Selection is enabled for the specified Presentation Context of the DICOM Associate; otherwise, it is false.

Remarks

If Role Selection is enabled, the roles for the Presentation Context can be retrieved using GetUserRole and GetProviderRole. To set the roles for the Presentation Context, use SetRoleSelect.

Example
C#
VB
using Leadtools; 
using Leadtools.Dicom;

   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application
