[perl-win32-gui-users] Win32::GUI help-URGENT
Hello there I am computer engg student in Singapore and am currently developing a perl application for which I need to develop a small and simple GUI. For this I came across this Win32::GUI module and feel its very easy to use. However I'm having trouble with it and was hoping someone could help me since posts in forums etc havent been much help. I thought mailing here directly would be the best thing to do. Firstly i downloaded the package but when i say ppm install Win32-GUI i get an error as follows: Error: No valid repositories; Error 500 Can't connect to ppm.Activestate.com:80 (connect: Unknown error) at D:/Perl/site/lib/PPM/Repository.pm line 84 Error: 500 Can't connect to ppm-ia.Activestate.com:80 (connect: Unknown error) at D:/Perl/site/lib/PPM/Repository.pm line 84 I feel either there is something wrong with my pre-instaled modules or im doing something wrong, but have no idea what it is. Also if i try to run a simple script to make a window with one button or any other script that uses this module I get the following error: Can't locate loadable object for module Win32::GUI in @INC (@INC contains D:/Perl/lib D:/Perl/site/lib .) at GUI.pl line 1 Compilation failed in require at GUI.pl line 1 BEGIN failed--compilation aborted at GUI.pl line 1 Once again I think i'm not sure why this error is coming. I did copy the GUI.pm file in all the directories specified. Please tell me what else I should do. I am in a hurry and need to start developing soon which wont take time once this problem is solved. I am hoping someone would reply to be as soon as possible. Any suggestions/help/advise to put me onto track would be much appreciated! Thank you for your time. Hoping to hear from you soon Regards Shuchi

Hi, I wouldn't use the Activestate Repository for win::gui - there are later versions available on the sourceforge site - you will have to manually install the module: http://sourceforge.net/projects/perl-win32-gui/ http://sourceforge.net/project/showfiles.php?group_id=16572package_id=12884 for perl 5.6 http://sourceforge.net/project/showfiles.php?group_id=16572package_id=104184 for perl 5.8 If you want to use a repository, have a look at http://perso.club-internet.fr/rocherl/Win32GUI.html it also contains the latest versions.

RE: [perl-win32-gui-users] Win32::GUI help-URGENT
Instead of copying, install it with PPM. Download the ZIP from Sourceforge for your build of Perl. I've run into the same thing when just trying to copy the appropriate files to their locations. If you use the one from Active state, it is only build .558. Sourceforge is .607 I believe. It looks like you are behind a Proxy. Did you read the Perl distribution docs on how to set up PPM (your environment) for a proxy? -Original Message- From: #SHUCHI MITTAL# [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 06, 2004 6:53 AM To: perl-win32-gui-users@lists.sourceforge.net Subject: [perl-win32-gui-users] Win32::GUI help-URGENT Hello there I am computer engg student in Singapore and am currently developing a perl application for which I need to develop a small and simple GUI.

RE: [perl-win32-gui-users] New Hook Method
Thanks for that, Steve. I'll be looking out for the new implementation.
In the meantime, I've been playing with some other messages and always
seem to hit the same problem with pointers to structures. When you say
you can't use Perl to resolve the pointer does that mean it is
impossible without XS code? Can you not just pack the correct
structure? For example, it would be nice to be able to select all items
in a listview without going through a slow loop like:
for (0..$mw-lvList-Count()-1) {$mw-lvList-Select($_)}
Now,
$mw-lvList-Select(-1)
would be nice, but it doesn't work!
Taking an idea from the VB world I tried this:
use constant LVM_SETITEMSTATE = 0x1000 + 43;
use constant LVIF_STATE = 0x0008;
use constant LVIS_SELECTED = 0x0002;
my $lvItem=pack(IiiIIp,LVIF_STATE,0,0,1,LVIS_SELECTED,,0,0,0,0);
$mw-lvList-SendMessage(LVM_SETITEMSTATE, -1, \$lvItem);
Needless to say, it fails miserably. I assume the problem is with the
pointer to the structure. Is the structure wrong or is the problem with
the Perl variable reference? I know that a Perl variable is represented
by a C structure internally; can you get a pointer to the actual data
value without resorting to XS code?
Thanks again,
Glenn

Hi Glenn,
I've been trying to get the ListView EditLabel feature to work. I can
turn it on OK and have got the handle to the edit control and through
that the control's contents. The problem is that the control is
created
and destroyed automatically, and it is difficult to get access to the
final data. According to MSDN, an LVN_ENDLABELEDIT notification is
sent
just before the control is destroyed, but I can't figure out how to
get
to that. Would the new Hook method work? Again, according to MSDN,
the
LVN_ENDLABELEDIT notification is sent in the form of a WM_NOTIFY
message. Would I have to grab that? That sounds like it may be biting
off more than I can chew... Can you offer any pointers? Could you
perhaps post a snippet of code showing how the Hook method works?
You can't do this with Hooks at the moment. Personally I am not happy
with the current hook implementation as it does not satisfy what I
originally intended it to do. A new hook implementation should come in
the next few days, and I'll add the ability to hook notifications as
well as messages.
The problem is that WM_NOTIFY messages are delivered with an lParam that
is a pointer to a structure containing the notification code (like
LVN_ENDLABELEDIT). While you can use the current hooks implementation to
catch WM_NOTIFY and see the wParam and lParam arguments, the lParam
pointer is useless to you in Perl and you can't use Perl to resolve the
pointer and get the notification code from it.
Watch this space...

RE: [perl-win32-gui-users] New Hook Method
Hi,
Arrrgh.
The Win32 API deals, in the most part, with pointers to structs rather
than structs themselves. You can't pass homemade structs as Perl
references to SendMessage and hope that they're magically converted into
C pointers, that would indeed be nice, but it just isn't how it works.
I recommend you take a look at the Win32::API module for Perl. This may
help you as it certainly helped me.

Re: [perl-win32-gui-users] New Hook Method
On approximately 1/6/2004 6:51 AM, came the following characters from
the keyboard of Stephen Pick:
Hi,
Arrrgh.
The Win32 API deals, in the most part, with pointers to structs rather
than structs themselves. You can't pass homemade structs as Perl
references to SendMessage and hope that they're magically converted into
C pointers, that would indeed be nice, but it just isn't how it works.
pack/unpack does seem to have a conversion feature that deals with
pointers, though, which I have to admit I have never figured out how to
use it, or for certain why the feature is included. None of the
examples show its use.
I've idly wondered, from time to time, if one could obtain a pointer to
a homebuilt struct via pack, and then pass that as an integer value via
Win32::API to a parameter that expects a pointer, and if that would
work. Of course, Win32::API provides support for passing pointers to
plain structs, so I've never had to worry about that in reality. But
then since SendMessage doesn't, maybe it would be useful there?
I offer these comments and speculations not in the knowledge that this
is a workable solution, but that it might be close to one... please
don't laugh me off the list if it is completely ridiculous. But it
seems I always have something else more important to do when I get near
the computer, rather than try out this sort of thing.
Another alternative, of course, is to use the Win32::API module to
create a new interface to the Windows SendMessage API rather than using
the one in Win32::GUI.
I recommend you take a look at the Win32::API module for Perl. This may
help you as it certainly helped me.
