|

In order to avoid having to pass down the parent window handle
|

through numerous levels of calls, we simply remember the window

handle of the active dialog in vhwndDialog. It is initially set

to (HWND)NULL and gets reset to this at the end of FDoDialog.
|
||
|
|
Each dialog stores it's window handle into vhwndDialog when it
|
||
|
|
handles the WM_INITDIALOG. Note that there are no cases of nested
|
||
|
|
dialogs, so having a single global works.
|
||
|
|
(As an example of where the parent window handle would have to be
|
||
|
|
passed down numerous levels, consider the FSaveFile case. It can
|
||
|
|
be called while the SaveAs dialog is up, or from Save (in which
|
||
|
|
case there is no dialog. It in turn goes several layers deep
|
||
|
|
and gets into routines like FWriteFile which can call AlertBox to
|
||
|
|
report a Disk Full error. So using a global makes a lot of sense.)
