SendCMoveRequest Method
See Also  Example
Leadtools.Dicom Namespace > DicomNet Class : SendCMoveRequest Method




presentationID
The Presentation Context ID. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data.
messageID
The Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
affectedClass
The class affected by the request. This will be a SOP Class or a Meta SOP Class.
priority
The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect.
moveAE
The name of the Application Entity to which to move the data.
dataSet
A DicomDataSet object that contains the Data Set to be moved.
Sends a C-MOVE-REQ message to a peer member of a connection.

Syntax

Visual Basic (Declaration)

Parameters

presentationID
The Presentation Context ID. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data.
messageID
The Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
affectedClass
The class affected by the request. This will be a SOP Class or a Meta SOP Class.
priority
The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect.
moveAE
The name of the Application Entity to which to move the data.
dataSet
A DicomDataSet object that contains the Data Set to be moved.

Remarks

Calling this method generates a call to OnReceiveCMoveRequest on the SCP. The SCP should respond by calling SendCMoveResponse which will generate a call to OnReceiveCMoveResponse.
