DM API METHODS AND PROPERTIES 161

DeleteProperty

Use this method to delete a property from the property list based on its

index (relative) position in the list. DeleteProperty uses a zero-based

index. After an item is deleted from the list, the list repacks itself.

Syntax

PCDPropertyList.DeleteProperty( lngNdx )

Parameter

Returns

Returns an HRESULT to receive the result of the call. S_OK indicates

success. Languages such as JavaScript, Visual Basic, and VBScript

return this as a function value.

Usage

Indexes in the list are not guaranteed to match the position in which

they were first added to the list. For example, assume you have a

PCDPropertyList of four items, with index values from 0 to 3. Perhaps

you want to delete the item with index value 1 and update the item with

index value 3. After you delete the first item, the list repacks itself. Now

the item you want to update has an index value of 2, not 3. For this

reason, you should use the GetPropertyIndex method to determine the

index item to delete.

Example

See the Example in the discussion of the PCDPropertyList object for

sample code that uses the DeleteProperty method.
