Although I don't feel confident advising because of my limited skills, I made this amendment to the wiki: That doesn't matter. Anyone has to learn. And besides of that, if only the developpers, who knows all ins and outs, can update the Wiki, it will never happen. ;) Reading the WIKI-text above, you'll see immediately what's wrong: you're not using the latest SVN version of Lazarus. I run svn update into Lazarus folder every day and not only once. This moment's Lazarus revision is 8893. Ok, another error in the wiki. You need the latest svn-version from fpc. All non-visible components are part of the FCL of fpc. The Lazarus- package is only a wrapper around the real components. So an update of lazarus is only needed if a new component is added. (or deleted) Sorry, but I can't resist: 'I've written some code and it raises an exception. Can anyone help me?' What is the exception: 'Incorrect password'? Or maybe: 'Can not resolve hostname'? I understand the way you feel not getting enough information to figure the problem out. Information I had last time just before posted this request seemed useless to me so I did not include it, don't know, can't remember what exactly was, I believe it was totally general. I'm sure that if it was providing something useful such as 'Incorrect password' or 'Can not resolve hostname' I wouldn't judge it the way I did. Offcourse. But information that looks like useless to you, can mean everything to the programmer. In the mean time, I read again article mentioned, followed every one of suggestions there and made some cleaning and privileges checking. Running sample application again, I get segfault mentioned on your reply. After svn-ing fpc from scratch I got revision 2820. Now, after svn-ing fpc and try to compile it (I have to do it, don't I?) using comamnd make all I get an error cannot find -lgpm. Let me find the cause and be back if necessary. You need to install the gpm-devel package. This is how it's called on Fedora, I'm not sure how to handle this on Knoppix. -- Met vriendelijke groeten, Joost van der Sluis CNOC Informatiesystemen en Netwerken http://www.cnoc.nl _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Looking at your next paragraph I conclude, drag-n-drop is not working good enough yet, or am I wrong? NOTE: I dragged an item from one listbox to another listbox.

Thank you, it is compiled. A couple of questions regarding this procedure: - I had fpc 2.0.2 installed on another path. After make install, related to path entries in file /etc/fpc.cfg did not changed to meet new path. This had as effect Lazarus to produce compiler errors not finding some units. Replacing related entries problem solved. I think FPC developers should be aware of this. - I have downloaded fpc using svn command. After downloaded, I run make install to install fpc.

[lazarus] Thread Behavior in Lazarus
I have been looking at threads in FPC/Lazarus over the last few weeks and I
found on the web a conversion of the old Delphi threads demo that was
partially working. I have added the {$ifndef win32} CThreads, {$endif}
code to enable thread linking on Linux. I have also got the Synchronize calls
to work by adding the '@' operator to the DoVisualSwap procedure reference. I
also had to remove the final refresh of the paint boxes as this caused a seg
fault on Windows. The new version of the code is now here:
http://www.proceduralminds.com/Files/LazThreads.tar.gz
The threads now work fine on Windows and on Linux in the Lazarus IDE,
unfortunately the Linux standalone program executes the threads sequentially,
i.e. not using time slicing? I am testing in Laz 0.9.13Beta 9-2-06. Anyone
any ideas?
I would value any insight into what is going on as I need to use threads in
my MSc dissertation project to be completed this September and I would
very much like to use Lazarus as the development platform.
Thanks,
Paul

How the threads are executed is not up to FPC: the PThreads

The FPC code does not decide anything about how the threads are

The threads now work fine on Windows and on Linux in the Lazarus IDE,
unfortunately the Linux standalone program executes the threads
sequentially, i.e. not using time slicing? I am testing in Laz 0.9.13Beta
9-2-06. Anyone any ideas?
How the threads are executed is not up to FPC: the PThreads
implementation is used to do the actual thread handling.
The FPC code does not decide anything about how the threads are
executed.
Thanks for the reply. Why would the behaviour change from running from the IDE
to executing from the command line?
The IDE uses probably different libraries than your command-line
program. CMem for instance. Is your program a GUI program or not,
and so on... There are many factors involved...

It runs well and perfectly threaded on FreeBSD 4.11 with fpc 2.0.2 and

You replaced several If..else with an assert. For example:
- If UseFont = nil then
-DebugLn('WARNING: [TGtkWidgetSet.TextOut] Missing Font')
- else begin
+assert(UseFontnil,'WARNING: [TGtkWidgetSet.TextOut] Missing
Font');
If UseFont is nil, then it almost always means, the calling code did
something wrong. The gtk intf should not continue, because otherwise the gtk
will give a warning, and this will be far less helpful, than the above.
It should not be replaced by an assert, because the warning should be
written even in non debugging code. It can only be replaced with an raise
exception, but that would be incomaptible to the other widgetsets.

Ok, I can revert it.
But I want to:
1. remove any write to console in release version of my program
Of course. In a release version you will hopefully use the functions
properly and then you will not see any output. If you have a bug, then the
program will not crash, but write a warning, that your user can tell you and
this will help you to fix the bug.
2. When I test my Delphi application, I noticed that function with any
strings operators work longer, even if then not reach that line (Delphi
make longer preamble to that functions) , enough to move that code to
subfunction - in FPC is the same (if somebody understand me)
That's because of the hidden exception frame.
AFAIK using string constants without operators do not create such frames.
That's why the lazarus code at all time critical places works without string
operators.

I have also heard of fblib http://fblib.altervista.org/ I have no well-formed opinion on this. Personally, I would use SQLDB. I've used it in projects and it works fine for me. It's also the best way to improve SQLDB. However: If you need database management routines (backup/restore/usermanagement etc). Then it's better to use fblib, or UIB (united interbase), Because SQLDB does not have that, and it's not planned in the near future. Michael.

Re: [lazarus] turboCASH on Lazarus proof of concept
Sounds good to me. I will try both. Gentoo installed the Server version, but I want to be able to just name a database file and not have to deal with host at this moment.

[lazarus] SqlDB with Firebird
I figured I would start a new topic on this. I installed Firebird Classic on my Windows XP machine. In Lazarus, I added a TIBConnection to a blank form. I put the full path to an example database (C:\Program Files\Firebird\Firebird_1_5\examples\EMPLOYEE.FDB) in the Database Field of the Object Inspector. I left the host blank as well as UserName and Password as I have not set any of these and the Firebird docs said they could be left blank. When I try to set the object to active, I get a response that unavailable database. I must be missing something. Is there a begineers tutorial on this component? How would I set host for a database running in embedded mode and how do I set users and passwords, if needed? _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

This is typically the result of a dirty build. Please make sure, your unnit

If you only need a String to pointer hash array:
There is already one in lcl/stringhashlist.pas

Re: [lazarus] Icon property of TTrayicon in win32 patch
Hello Christian, First I would like to thank you for your effort into creating the patch and helping us improve Lazarus. However, I (and the lazarus developers) feel that it would be better if we implement a proper TIcon instead of adding a work around the current TIcon problems on components. Would you like to help us create such better TIcon? thanks again, -- Felipe Monteiro de Carvalho _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
