SetIntValue(DicomElement,IntPtr,int) Method

Summary

Sets the integer value(s) of a Data Element.

Syntax
C#
VB
C++
Java
public bool SetIntValue( 
   DicomElement element, 
   IntPtr value, 
   int count 
) 
Public Overloads Function SetIntValue( _ 
   ByVal element As DicomElement, _ 
   ByVal value As IntPtr, _ 
   ByVal count As Integer _ 
) As Boolean 
public boolean setIntValue(DicomElement element, int[] intValue, int count) 
public: 
bool SetIntValue(  
   DicomElement^ element, 
   IntPtr value, 
   int count 
)

Parameters

element
An item in the Data Set.

value
Pointer to a integer that contains the integer value(s) to set. If you want to set multiple values in the Value Field, put all long values in value and set count to the appropriate number of values.

count
Value that represents the number of values to set in the Value Field. If you want to set multiple values in the Value Field, put all the integer values in value and set count to the appropriate number.

Return Value

true if the integer value(s) were set successfully. false if could not set the integer value(s) of the Data Element.

Remarks

Note: The user is responsible to allocate the memory for value. If you want to set more than one value in the Value Field of the Data Element, put all the integer values in an array of integer values, set value to the address of the array, and set count to the corresponding number of entries. For example, if you wish to set three integer values in the Value Field of the Data Element, create an array of integer values containing the three integer values, set value to the address of the array, and set count to three.

If more than one value is stored in the Value Field of the Data Element, you must set all values at the same time.

This method can be called only if the Value Representation of the Data Element is:

For more information about Value Representations, refer to Default Value Representation Table.

Example

This example will initialize a DICOM Dataset and then insert different types of elements, update their values and finally verify those values by reading them back from the Dataset.
