Leadtools.Dicom Namespace > DicomDataSet Class : GetShortValuePtr Method

element: An item in the Data Set.

index: The zero-based index of the first value to retrieve, when more than one value is stored in the Value Field.

count: Value that represents the number of values to retrieve when more than one value is stored in the Value Field. In most instances you will only retrieve one value so this parameter will be equal to one.

Returns a pointer to a short value, stored in the Value Field, of the specified element.

Syntax

Visual Basic (Declaration)
Public Function GetShortValuePtr( _ ByVal element As DicomElement, _ ByVal index As Integer, _ ByVal count As Integer _ ) As IntPtr

Visual Basic (Usage)	Copy Code
`Dim instance As DicomDataSet Dim element As DicomElement Dim index As Integer Dim count As Integer Dim value As IntPtr value = instance.GetShortValuePtr(element, index, count)`

C#
public IntPtr GetShortValuePtr( DicomElement element, int index, int count )

Managed Extensions for C++
public: IntPtr GetShortValuePtr( DicomElement* element, int index, int count )

C++/CLI
public: IntPtr GetShortValuePtr( DicomElement^ element, int index, int count )

Parameters

element: An item in the Data Set.
index: The zero-based index of the first value to retrieve, when more than one value is stored in the Value Field.
count: Value that represents the number of values to retrieve when more than one value is stored in the Value Field. In most instances you will only retrieve one value so this parameter will be equal to one.

Return Value

A pointer to a short value stored in the Value Field of the specified Data Element. null if The length of the Value Field is 0, the method was called for the incorrect Value Representation type, or the method was called for a folder (sequence) element.

Example

For an example, refer to SetIntValue.

Remarks

If you have more than one value stored in the Value Field of the specified Data Element, you can retrieve one or more of those elements. For example, if the Value Field of the specified Data Element contains three short values, and you are only interested in retrieving the last two short values, set index to 1 and count to 2. This tells the method to retrieve the short values starting at position 1 (the index is zero-based) and retrieve two values. Therefore you would retrieve the values in positions 1 and 2 in the Value Field.

This method can be called only if the Value Representation of the Data Element is DicomVRType.OW, DicomVRType.SS, or DicomVRType.US. For more information about Value Representations, refer to Default Value Representation Table.
