Syntax

C++

public virtual DicomDataSet[] FindStudies( 
   FindQuery query 
)

  
Public Overloads Overridable Function FindStudies( _ 
   ByVal query As Leadtools.Dicom.Scu.Common.FindQuery _ 
) As Leadtools.Dicom.DicomDataSet()

public: 
virtual Leadtools.Dicom.array<DicomDataSet^>^ FindStudies(  
   Leadtools.Dicom.Scu.Common.FindQuery^ query 
)

Parameters

query
The Leadtools.Dicom.Scu.Common.FindQuery which contains the parameters for the query.

Return Value

An Array of Leadtools.Dicom.DicomDataSet objects which contains the query results.

Remarks

Calling this method while the Processing property is true will result in an InvalidOperationException being thrown.

If the operation is cancelled this method will throw a ClientCommunicationCanceled exception.
