Re: [lazarus] Patch for reading LRE encoded BMP files
Sorry to ask before searching on the code base but... is there code to ENCODE RLE BMP files? I am building a support aplication (something like VNC with some aditional things we need)... Thanks. Horacio Sebastian Günther escribió: Hi *, attached is a small patch which enables the LCL to read RLE encoded BMP files (successfully tested with some hundreds of small 8 bpp bitmaps, 4 bpp should work as well).

[lazarus] Internal debugger for Lazarus
I was thinking exactly the same Yesterday I was talking about Lazarus to one of my clients, and he asked me why I am steel using Delphi... and the my answer was: 1) The internal debugger is not as usefull as the Delphi one... The most important missing feature is the Object support (evaluate or modify property values, or call methods while debugging). 2) Some thirty party components that are not currently available (currently I am using mostly JVCL) For me the debugger is the most important missing part... Is anybody working on a internal debugger for lazarus? Did anybody started such a project yet? Does anybody have something to start from? Thanks! Horacio Bogus?aw Brandys escribió: Peter Vreman wrote: If the debugger gdb can support the dwarf debug info the size of the binary will be already a lot smaller.

First: Please reply at the bottom of the messages. The answer to your question was already in my reply quoted above. The debugger gdb support for dwarf was not good enough and not supported on all platforms (especially windows). It is improving, but it needs to be tested well before we can make dwarf debuginfo for some platforms the default in fpc. Peter We need a native debugger support for FPC/Lazarus programs on all platforms.That's the big issue everyone seems to avoid talking about...

Re: [fpc-devel] "Invalid field size : 8"
It seems that the Size field shoud be 0 (zero) for numeric fields... The size property of TField have different meanings for the different field types. So, you should not set the size property of an Integer field to anything (the default 0 value is correct). Hope this helps. Horacio As you can see problem is with setting TField.Size to 8 for ftInteger field , but I've also modified code to force Size of ftInteger to 4 and error still persisted. questions: Is that a bug inside fields.inc or just a calling layer must prepare TFieldDef to avoid this exception ? Is that a known problem ? Regards Boguslaw Brandys _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Re: [lazarus] Debugging multitheaded application
Mark... I am not too new to linux, but enaught to don´t know how to open a second x server instance. I don´t expect to use a second computer so option 1 or 2 are good to me... Could you explain me how to do either of them or point me to some place I could found the way... THANK YOU! At the other side... it can´t be fixed? just to know!

[lazarus] Debugging multitheaded application
Hi, I am porting a multithreaded server application from Delphi to Lazarus (linux). I am using the cThreads unit, and the TThread class. The program is not working properly... I don´t know why yet. But it compiles and starts! I´m happy for that. The program listen on a port for TCP connections using Synapse (or Indy on Windows... but I didn´t tested Indy4Lazarus yet on Linux... does it works for a basic Tcp Server app? ). When the connection is incoming, it creates a new thread for that connection that keeps the connection open (and the thread is trying to read the socket all the time). The problem is that while I am trying to debug the application, most of the times the debugger (gdb) hangs the X Server... Is somebody else having such a problem? Does anybody have any clue about what is happening? I need to fix the application... and without the debugger will be very complex... Any help will be appreciated. Horacio

It´s grait to know that there is already something on the way! I don´t have too much free time to work on this projects... As I said I think both of them should finally exists on Lazarus (RAD for Web and RAD for Console)... but yes Another point about Lazarus and Application kinds: Shouldn´t the IDE show only the components that are usefull on the current application kind? How should this be achieved? I mean, in the current component registration process there is not place to indicate on what kind of applications the component could work. Just an idea.

Re: [lazarus] Console GUI / Web Applications Support for Lazarus RAD
Yes... with Console GUI Applications I mean that kind of applications (like Free Vision applications). About Intraweb, I have nothing to do with them, but I like the tool. Intraweb is a RAD Web development environment that uses Delphi (and Kylix)as IDE and Compiler.In an Intraweb project, you have Intraweb Forms and Data Modules(standard)...You fill the forms with Intraweb Enabled Components (no the standard ones),and you program the components events, as you normally do on any GraphicalGUI Application (Standard Lazarus Application).Once you compile, Delphi (or Kylix) creates one of the following: a) A Web Server application (with the application embedded) b) An ISAPI Module (for IIS) c) An DSO Module (for Apache)This executable modules, generates for the user, the HTML+_javascript_ pages,that acts the way your application shoud. Everytime the user takes an action(like pressing a button, or selecting an item on a combobox), the browserask a new page to the server (in any of the 3 formats), it triggers theproper code (programed in Object Pascal), and then it generates the newpage.You could see more on http://www.atozed.com/intraWeb/ Horacio - Original Message - From: L505 To: lazarus@miraclec.com Sent: Saturday, September 03, 2005 3:26 PM Subject: Re: [lazarus] Console GUI / Web Applications Support for Lazarus RAD Some years ago I started a project in Delphi/Kylix that should finally allow me (and any other developer) to create Console GUI Applications using Delphi, in a pure RAD way, using non-visual standard components, and a set of components I was developing.

[lazarus] Console GUI / Web Applications Support for Lazarus RAD
Hi, Some years ago I started a project in Delphi/Kylix that should finally allow me (and any other developer) to create Console GUI Applications using Delphi, in a pure RAD way, using non-visual standard components, and a set of components I was developing. I got the base idea from de KOL project, that was able, throw a Mirroring System, to use the Delphi environment to develop de KOL projects. I never finished this project... I only created the base console application and some components... and started building the mirroring system. But it never worked (I never finished it). The fact is, I think it would be a grait thing to have this support integrated in Lazarus (as is Intraweb in Delphi). My idea is, as I said, to contribute all this thing to the lazarus project (to be LGPL also). Does anybody tried to do something like this before? Where should I start from? (to create the new application type in the IDE, and to make the IDE work with this new kind of TtxtForm) Is anybody interested to participate in this project? At the same time, I want to know if someone is working in a Web Applications support for Lazarus ala Intraweb? Horacio
Re: Getting the word out

[lazarus] Lazarus section on www.Torry.net
People, FYI, I today asked Maxim Peresada (torry's site owner) when will he add a Lazarus section to his site and he answered: --- I know what Lazarus is well. As I answered in Borland news group, first task is to fix all problems that Torry's already has after server and database engine changes. During September we will try to bring Torry's new look and make it full with new features. I already added Lazarus section in my to-do list, but it will be implemented after all other things will be fixed. Estimated date is the middle of September. I think this are grait news! Thats why I am sharing this with you. Keep the good work!
