    Echo Method (DicomAssociation)
    In This Topic
    Sends a verification request (C-ECHO) over a "stand-alone" DicomAssociation and returns the result
    Syntax
    'Declaration
     
    
    Public Function Echo() As Integer
    'Usage
     
    
    Dim instance As DicomAssociation
    Dim value As Integer
     
    value = instance.Echo()
    public int Echo()
    public:
    int Echo(); 

    Return Value

    Integer
    Remarks

    DicomAssociation must be open before sending out C-ECHO request.

    Although in theory the remote entity may return a status other than 0 to indicate an error, in most circumstances (such as remote machine turned off), this method will fail with a trappable error, such as "Fail to connection at TCP level".

    The C-ECHO status can also be found in the LastStatus property of DicomAssociation.

    For more details of sending C-ECHO via TLS, see Echo method of DicomGlobal object.
