OCX implementation is outstanding

[Stephan Hennekens]

Dear all,
I have tested the latest Xailer and focussed on the ActiveX support. I was
happy to find out that I was able to use one of my favorite components
MapObjects from ESRI without any problem!!. The way ActiveX is implemented
in Xailer is very elegant (comparible with MS Visual Studio and even more
intuitive that handled in Delphi). Within half an hour I had build a
MapViewer with zooming capabilities. And the application is solid rock. No
GPF's!!
I have also other xHarbour related products, but was unable to get a stable
of or even running application.
The test project is included and if you want to play with the sample you
will need to dowload and install a trial version of MapObjects Lite
(http://www.esri.com/software/mapobjectslt/download.html).
I have a question though. On the main form, on two panels, I have also
placed two other components. One is a scalebar at the bottom, and one is
legend tool on the left. When the main form is initialized these two
componets are created, but they they not really become visible. Does anybody
have a clue in what direction I need to find a solution. I have used these
components succesfully in other programs (using a VB-alike IDE), but then it
was simply dragging them from a component tool bar on to the form. Maybe it
has something to do with early or late binding of the controls.
Best wishes,
Stephan

I'm trying to run the sample, but I'm having several problems:
1) I've downloaded and installed the component, but it doesn't include the
legend and scalebar ocx's. Where can I download them?
2) I've downloaded sample data, and I've changed the method
TMainForm:FormShow() to load other maps, but I get nothing. Please, send me
correct sample data or tell me how to replace for another maps.

Jose,
I have posted a zip file on my webserver

The zip contains the missingcontrols and a sample shape file (always

I downloaded and checked it, without success. I searched in google how to
use those components, but there are very few references, several ones in
some asian language which I don't know at all.
It seems the problem is about how to use them. If you find any sample (for
example in Delphi) it would help.
BTW, almost a year ago, I did a prototype of a similar program. It consist
in a map with several 'sensible' points which can be clicked to show info
about them. That is, an interactive information system for a espeleologist
association, which shows information about caves in the province of Almeria
in Spain. Here are a couple of screenshots:

Thanks for your efforts Jose.
The way I coded the sample should work, because it also worked in UltimAde
(a VB alike IDE with Clipper language, but no longer supported).
Anyway, the map control works fine in Xailer, which is a very good thing.
Have you also been able to get the map on the screen?

Yes, the map is shown correctly, but the other two panels show nothing. I
saw that the map is assigned to the legend object by calling
:SetMapSource( ::oMap ). Perhaps the problem is about assigning an OLE
object to a property of another object; I'm not sure. So, I'd like to see a
working sample (preferable in Delphi) to review it deepper.

Jose,
unfortunately the legend and scalebar control don't work in Delphi. The
troubles already starts when creating the type libs.

Now that I have bought a license for Xailer I can run the applications
outsite of the IDE. With the MapObjects control however there is new problem
when I close the application. It GPF's.
Any idea how to solve this problem?

Jose, could you please review? This is certainly a low level problem.
You can download the xailer project from here:
http://www.synbiosys.alterra.nl/download/mapviewer.zip
The sample uses the MapObjectsLT2 components you have installed a few weeks
ago.
In this sample I have excluded the Legend and Scalebar control, so the
problem seems fully at the account of the Map object.
Best wishes,
Stephan

I found where the GPF ocurrs, but I've not been able to avoid it. The GPF
ocurrs inside DAO350.DLL just *after* the program terminates. Here is an
extract of an external debugger dump:
00000000 - in C:xSailUsermapviewerMapViever.exe
Thread Ended : 3500
Thread Ended : 3460

Please, note that every thread is finished before the GPF arises, so it
makes more difficult to fix. I don't know why, but I suspect that there is
something in that component that is not correctly released.
Well, I still continue researching.

Thanks for explaining Jose,
remarkable though that applications I wrote with Delhi and UltimAde (VB
alike COM based tool with Clipper syntax) don't have this problem.
I'll see if these application also use DAO.

Jose,
You are right. When I unregister DAO350.DLL there is MapViewer exists
without a problem. A pity, MapViewer does not use all functions of
MapObjects so that DAO350.DLL doesn't need to be loaded. How can test with
DLL/OCX calls DAO350.DLL?

It seems that the component loads DAO internally if it's available. I don't
know what it needs from DAO, nor how to avoid it yet. Of course, I assume
that unregister DAO to run MapViewer is not aceptable to your users, so I'll
continue searching a fix.

That's because the IDE runs the app in 'debugging' mode, and receives all
exceptions, including GPFs. But, GPF exceptions are silenty ignored by the
IDE as the app itself should show the error. Unfortunately, the app doesn't
show any error because it's terminated at that time.
BTW, memproof, that is an process and debugging tool, hides also the GPF.

Jose,
for now I have a dirty trick that probably will not work in all cases. At
startup DAO350.DLL is renamed to DAO350__.DLL and when closing the main form
the reverse action takes place. No good practice, but it clearly shows this
DLL is causing the pain. Still I don't know why this DLL is loaded; it;s not
needed at all.
Is there a way to get the handle to DLL in memory and then kill it?

Stephan,
I've found it!
I don't know why, but OLE libraries are not released before program exits,
and this is the cause of the problem. Please, add a simple call to
CoUninitialize() just before finish, for example, at main form's OnDestroyed
event:
METHOD FormDestroyed( oSender ) CLASS TMainForm
CoUninitialize()
RETURN Nil
Also, 'wrap' that function as:
#pragma BEGINDUMP
#include "windows.h"
#include "xailer.h"
XA_FUNC( COUNINITIALIZE )
{
