Re: [fpc-pascal] PASCAL programming for Novice
Any tutorials out there on using Event Driven programming with Free Pascal? I'm hoping to create a server/client combo that will need to respond to both input from the client part, and input from the server part my server/client combo app +--+ User --- | server part--client part| -- another server +--+ So, when my user talks to my server, I need to be able to respond, and when the other server talks to my client, I need to be able to respond. Anyway, just a simple event driven programming tutorial using some version of Pascal will probably help. Thanks Michael Van Canneyt wrote: On Sat, 9 Jun 2007, Francisco Reyes wrote: Leonardo M.

Re: [fpc-pascal] PASCAL programming for Novice
It's what I like to call a pass through server. My ISP won't let me send email unless I'm on their network (at home). So, I have a server I wrote in VB that listens for a connection on a non standard port. When connected, it connects to my ISP's SMTP server. Anything it gets from the email client, it passes to the server. Anything it gets from the server it passes to the email client. Works like a charm. Only problem is that it's in Windows. I'm working towards getting rid of that windows box and replacing it with linux. So, I need to re-write this app in Linux. It's really the event part of it that I'm concerned with. Leonardo M. Ramé wrote: Are you trying to create a Peer-To-Peer architecture?, something like Windows Messenger?. I don't know how to implement that type of architecture, you can do a simple google search to find examples, but since it uses socket communications you can implement it using lNet or Synapse libraries with FreePascal.

Re: [fpc-pascal] Linux Linking Error]
(I sent this earlier today, but haven't seen it on the list. It's been over 5 hours, so I'm resending. I'm sorry if you end up getting both!) From the FPC IDE. I have not installed Lazarus at this point. I'm not sure how to compile from the command line. I'm sorry, I'm a lame Windows person trying to make it in the Linux world, so command line calls aren't second nature to me. I can't even get the mouse to work in the FPC IDE! So, if you could give me the command I should use to compile, I'd be happy to post the full error message. Thanks again Rick Michael Van Canneyt wrote: On Sun, 3 Jun 2007, Rick Seiden wrote: Using Ubuntu 6.10 under VMWare, I get an error when I try to compile any program.

The text mode IDE or the Lazarus IDE. It would be instructive to try and compile from the command-line, this way you'll get the complete error message. In the case of Lazarus, start lazarus from within a console window. The error messages of the compiler and linker will then also be displayed on the console window.

[fpc-pascal] Linux Linking Error solved
I emailed yesterday about an error when compiling in Linux. The error I received was Error while linking. I figured out that the permissions on /usr/bin/ld is set to root, and I'm logged in as a different user. When I sudo fp to start Free Pascal, I am able to compile without a problem. Just wanted to share the solution.

Re: [fpc-pascal] Linux Linking Error solved
-rwxr-xr-x 1 root root 444104 2006-06-08 04:09 ld You would think that would allow me to execute it as a normal user. The only thing I shouldn't be able to do as non-root, non-root-group member is write it, but... I was going to copy and paste the output to prove that it didn't do it, but when I tested it this time, it did work. I swear that the error said it couldn't find /usr/bin/ld. I just did ls, saw it there, with the root ownership, and then ran sudo fpc sockser.pas, and the error went away.

[fpc-pascal] No Browser Info Available
I'm having problems running fp ide under Ubuntu 6.x under VMWare Workstation 5.5. I go to an xterm session, and then run fp. The first mouse click generates an error that is obviously from FP. It says No Browser info available with an OK button. After that the mouse won't work in the terminal window at all. I've searched and can't find anything on this. Anyone have any ideas?

Re: [fpc-pascal] Timers in FPC
There's a contributed units http://www.freepascal.org/contrib/db.php3 link on the freepascal.org home page. Perhaps it could go there. Right under it is a Contribute http://www.freepascal.org/contrib/add.php3 link that allows you to add it to the contributed units database. I know this isn't adding it to the base RTL stuff, but it's a start for now, no?

I just wondered if there was something like that built into FPC that I missed. I would like to compare the implementations, or share mine if FPC doesn't have one. You're welcome to share yours.

Re: [fpc-pascal] Socket samples besides the bastisoft site?
I second that motion. I've been trying to figure out how to use the example in the rtl manual to create a simple server/client connection, and I've been having problems. An example outside of that would be very helpful. A tutorial. Something.

[fpc-pascal] RTL Manual pages 1056-1057 code listing question
I copied the code for socksrv.pp on pages 1056-1057 into FPC, and got a compilation error. I double checked the code, and it is the same as what's in the manual. My system: Windows XP FreePascal IDE for Win32 for i386 Target CPU: i386 Version 1.0.8 2006/08/21 (Compiler Version 2.0.4) (Debugger GDB 6.2.1) The error I get on Run/Compile is: socksrv.pp(34,26) Error: Call by var parameters have to match exactly: Got ShortString expected TInetSockAddr The error I get is on the following line: if not Accept(S,FromName,Sin,Sout) then I looked in the manual, and it defines Accept as follows: function Accept(Sock: LongInt;var Addr;var Addrlen: LongInt) : LongInt function Accept(Sock: LongInt;var addr: TInetSockAddr;var SockIn: File of ;var SockOut: File of ) : Boolean function Accept(Sock: LongInt;var addr: TInetSockAddr;var SockIn: text;var SockOut: text) : Boolean function Accept(Sock: LongInt;var addr: String;var SockIn: text;var SockOut: text) : Boolean function Accept(Sock: LongInt;var addr: String;var SockIn: File of ;var SockOut: File of ) : Boolean Based on the code, it appears that the example code is trying to use fourth definition, but the compiler appears to be expecting the third definition. I have experience with Delphi, and have used it in the past to write socket based code. I just don't have experience with FPC. Any help you can give as to why the code from the manual isn't working would be appreciated. Thanks in advance Rick PS: I searched the archives before posting.
