Our 16 bit Windows application handles dialog boxes on Windows 3.11.
We have a problem with lost GDI resources:
A dialog box is created with CreateDialogIndirectParam(). It has some 50
edit controls each attaching a font with CreateFontIndirect(). When the
dialog box has terminated, 2% of GDI resources are lost according to
Heapwalk. The fonts are released with DeleteObject() and the dialog box
is terminated with DestroyWindow().
If we run the same dialog box a second time, no further GDI resources are
lost.
According to Heapwalk ALL allocated GDI handles are released.
The problem becomes urgent, since we use many different dialog boxes, that
will each eat about 2% GDI resources, when run the first time.
Thanks for your comments,
Tore
