OCX questions

[Oleg]

Dear developers!
I try to create my first sample with OCX ListView (see attached project).
I have a few questions.
1. Is it possible to set focus on ListView (or other OCX) component after
program start and move from one control
to another (oButton to oListView and vice versa) with TAB key?
All my attempts were unsuccessfull. I tried oListView:SetFocus and
TListView:KeyDown event (see source).
2. When I import ActiveX in Xailer (Components menu), resulting .ch file
contains wrong #xtranslate directives instead of #define?
I have to change it to #define manually. I think it is a bug.
3. Debugger cannot stop on the breakpoints inside the WITH OBJECT
where I create OCX object (for example see line 51 in the Form1.prg)?
4. Are there any free tools to inspect all properties, methods and events of
defined OCX and other classes using in this OCX?
Something like Delphi internal Type Library Editor?
5. Maybe you know, Is there any CommCtl32 library guide in the Internet?
Thank you.
Oleg.

I don't have that OCX in my system, and I cannot test it. Is there any place
from where I can download it?

Yes, there was a bug, already fixed. Sorry for the inconvenience.

It's working fine here. The program stops just in that line (later it GPFs,
as that OCX is not present in my system). Please, check that all modules has
been compiled with debugger info (rebuild the whole project and test again).

Well, Xailer creates a class based on the OCX's type library. If you want to
view the type library yourself, you may use the tool "OLE-COM Object Viewer"
that comes with MS platform SDK

Search into MSDN.

It seems to me that this ActiveX ships with any standard Windows
installation.
It has name 'Microsoft Listview Control, version 5.0 (SP2)' and is included
comctl32.ocx together with TreeView, ImageList an so on.
It is placed in WindowsSystemcomctl32.ocx on Win98SE,
and in WindowsSystem32comctl32.ocx on WinXP Prof.

Debug info is included, I rebuild full project, but If I set breakpoint on
line with
:nAlign := alTOP and below
debugger does not stop.
Maybe the reason that I use combobox fixes from XailerUpg.rar that I
download recently.
Please look at it carefully.

Jose,
I found that compiled test10.exe works on Win98SE with described problems,
but does not work at all on Windows XP Prof SP2 (fails at Listview creation
with GPF
OLEADDRef(0)
TOLEAuto():New(306)
TListview():Create(64)
.... ).
Listview control is registered. I also tried to re-register it, but
test10.exe does not work
in any case.
Regards, Oleg

I've just tested again and it still works fine. I've put a breakpoint at
that line (:nAlign := alTOP) and I've compiled and run the program. Then, it
has stopped exactly at that line. I've pressed F5 to continue running and
I've got a GPF due the absence of the component.

Perhaps it has a different CLSID than in w98. Try to generate the class
again from the IDE in XP. Then, post the CLSID here (it appears at the
beginning of the class), to check if it's present in my system.

Jose,
If so many problems with Listview, let's forget about it (I also will have
WinXP till Monday)
The same problem exists with Microsoft FlexGrid.
I cannot move between FlexGrid and button with TAB key,
and cannot move inside FlexGrid with arrows keys.
See my attached sample.
You can download FlexGrid ActiveX (from my Win98 system)
from www.cluster.samara.ru/flexgrid.zip
