ReleaseNativePointer

Description

Releases the pointer to an OLE object that you got with GetNativePointer.

Applies to

OLE controls and OLE custom controls

Syntax

olename.ReleaseNativePointer ( pointer )

Argument	Description
olename	The name of the OLE control containing the object for which you want the native pointer.
pointer	A UnsignedLong variable that holds the pointer you want to release. ReleaseNativePointer sets pointer to 0 so that it is clearly no longer a valid pointer.

Returns

Integer. Returns 0 if it succeeds and -1 if an error occurs.

Usage

Pointer is a pointer to OLE’s IUnknown interface. You can use IUnknown::QueryInterface to get other interface pointers.

When you call GetNativePointer, PowerBuilder calls OLE’s AddRef function, which locks the pointer. You can release the pointer in your DLL function or in a PowerBuilder script with the ReleaseNativePointer function.
