Deleteobject function fails

Posted: Thu Sep 27, 2018 11:18 AM

Hi,

In this sample deleteObject() function fails, because do not release hBrush object.
There is no DC context associate.

Please, help me.

Regards.

Code (fw): Select all Collapse

//-------------------------------------------------------------------------//
STATIC FUNCTION PruebaRecursos()

Local hBrush
Local l1, l2

hBrush:= CreateSolidBrush(CLR_RED)

l1:= isgdiobject(hbrush)
l2:= deleteobject(hbrush)

MsgInfo(Transform(l1, ""))  // .t.
MsgInfo(Transform(l2, ""))  // .f.
return nil

Your sample works fine here:

Code (fw): Select all Collapse

MsgInfo(Transform(l2, ""))  // .t.

MsgInfo(Transform(l1, "")) // .t.
MsgInfo(Transform(l2, "")) // .f.

Where is the need to use Transform() here?
We can directly write

MsgInfo( l1 )
MsgInfo( l2 )

Or is there any special reason for using transform() ?
