Overloads Public Function SetIntValue( _ ByVal element As DicomElement, _ ByVal value As IntPtr, _ ByVal count As Integer _ ) As Boolean |
Visual Basic (Usage) | Copy Code |
---|---|
Dim instance As DicomDataSet Dim element As DicomElement Dim value As IntPtr Dim count As Integer Dim value As Boolean value = instance.SetIntValue(element, value, 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.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.

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.Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
