A FEW WORDS FROM THE EDITOR I'm very sorry for the delay in publishing this issue, but I had some personal problems these weeks, fortunately solved by this time. Well, this issue will be brief because I'm almost on vacation and I'm preparing it almost on the rush. I'd like to thank those who are helping us get more subscribers. I hope in the future it translates into more contributions for the newsletter to make it more interesting. By the way, if you solved a particular programming problem, I'd like to invite you to share your code in this newsletter like Victory Ferndandes, S.S.B. Magesh Puvananthiran and Charl Linssen and doing in this issue. My thanks to them. In the next issue we'll have material from Alirio Gavidia. I'd also like to thank Dave Murray for taking care of the "Delphi on the Net" section, bringing you links to new Delphi content on the Internet. There are many interesting things for this issue. I'd like to recommend you the tutorial "How To Ask Questions The Smart Way". Please give us a hand to help us reach 10,000 subscribers in the next months.

SOLVING LINEAR EQUATIONS WITH DELPHI USING THE GAUSS METHOD Victory Fernandes <victory @ e-net.com.br> sent us his application MatriX Version 1.2 for solving linear equations using the Gauss method for reducing a matrix. The source code is too big to be attached to the newsletter, so we put them available for download at: http://www.latiumsoftware.com/download/GaussSRC.zip (~174Kb) The compiled executable is also available for download: http://www.latiumsoftware.com/download/Gauss.zip (~421Kb) Both downloads include a ReadMe file explaining the project. ________________________________________________________________________ 3. MAKING AN APPLICATION A TCP/IP CLIENT (WITH SAMPLE CODE)... By S.S.B. Magesh Puvananthiran <sesba @ hotmail.com> Some Sample Code... =================== This article is intended to show how we can use the TClientSocket component in Delphi as a TCP/IP client against any TCP/IP server. The server could be written in Delphi using TServerSocket component or any piece of code that acts as a TCP/IP server. In my case, I'm interacting with a Java code acting as a TCP/IP server. In my project, I'm just sending a bunch of bytes to that Java server and the Java server reads the bytes and does some tasks, sending a different bunch of bytes as a response to the Delphi client. In this article, let me give you some sample code I used in that project since some people asked me to send the source code for this socket communication by sending separate e-mails. I appreciate them for their interest. Here U Go!! Enjoy!!! My project uses nearly nine forms and all of them need to interact with the Java server at least once. So I added a DataModule and put a TClientSocket component there. The following is the code for that: unit DataMod; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, ScktComp, OleServer; type TdmDataModule = class(TDataModule) csClientSocket: TClientSocket; procedure csClientSocketError(Sender: TObject; Socket: TCustomWinSocket; ErrorEvent: TErrorEvent; var ErrorCode: Integer); procedure csClientSocketRead(Sender: TObject; Socket: TCustomWinSocket); procedure DataModuleDestroy(Sender: TObject); private { Private declarations } public FWaiting : boolean; { Public declarations } end; var dmDataModule: TdmDataModule; implementation {$R *.DFM} procedure TdmDataModule.csClientSocketRead(Sender: TObject; Socket: TCustomWinSocket); //Reading data back from server thru socket var Buffer : array [0..4095] of char; BytesReceived : integer; MemoryStream : TMemoryStream; begin while FWaiting do begin MemoryStream := TMemoryStream.Create; try // This time delay depends on the network traffic and also you // can put the time delay between reads. I've just put some 200 // milliseconds for my application before it starts from the // server. Sleep(200); while True do begin BytesReceived := Socket.ReceiveBuf(Buffer,SizeOf(Buffer)); if (BytesReceived <= 0) then Break else begin MemoryStream.Write(Buffer,BytesReceived); end; end; FWaiting := False; MemoryStream.Position := 0; // XMLResponse is a global StringList I'm using in my // application to convert the bytes received into string // You can use other ways to get the contents of a MemoryStream XMLResponse.LoadFromStream(MemoryStream); finally MemoryStream.Free; end; end; end; procedure TdmDataModule.csClientSocketError(Sender: TObject; Socket: TCustomWinSocket; ErrorEvent: TErrorEvent; var ErrorCode: Integer); // Whenever you get a specific type of error while running the client // you will be given a messagedlg showing that the error has occured; // at that time you have to check whether the server is running // correctly or not and if needed make the server run properly and // then say OK. // Then csClientSocket.Open will try to reconnect to the server. So at // this time if some transaction is in the middle you have to send the // same stuff again after reconnecting. begin case ErrorEvent of eeGeneral : begin if MessageDlg('Error Connecting to Java server!' + #13 + 'Check the server status and try again!!', mtInformation, [mbOk], 0) = mrOk then csClientSocket.Open end; eeConnect : begin if MessageDlg('Error Connecting to Java server?' + #13 + 'Check the server status and try again!!', mtInformation, [mbOk], 0) = mrOk then csClientSocket.Open end; eeSend : begin if MessageDlg('Error Connecting to Java server?' + #13 + 'Check the server status and try again!!', mtInformation, [mbOk], 0) = mrOk then csClientSocket.Open end; eeReceive : begin if MessageDlg('Error Connecting to Java server?' + #13 + 'Check the server status and try again!!', mtInformation, [mbOk], 0) = mrOk then csClientSocket.Open end; eeAccept : begin if MessageDlg('Error Connecting to Java server?' + #13 + 'Check the server status and try again!!', mtInformation, [mbOk], 0) = mrOk then csClientSocket.Open end; end; end; procedure TdmDataModule.DataModuleDestroy(Sender: TObject); begin //Closing the socket connection csClientSocket.Close; end; end. Once you are done with the DataModule, you can include this DataModule in the units where you need to interact with the server, thereby you can avoid writing code to read data back from the server in various places of the project. You can set the Host/Address and Port Number of the server to communicate at runtime through runtime parameters (I assume Delphi people are aware of that runtime parameters). Then, in the project's main form's FormCreate event, write the following code to connect to the server, i.e. set the IP address and port number of the server in the TClientSocket component and set Active to True. //Connecting to the Java server on a particular port try with dmDataModule.csClientSocket do begin if Active then Active := False; // Getting the Address or Host Name of the server through the // runtime parameters Host := ParamStr(1); // Getting the Port Number of the server at which the server // listens through the runtime parameters Port := StrToInt(ParamStr(2)); // Making the connection active Active := True; end; except on ESocketError do begin MessageDlg('Unable to Connect to Java Server ' + #13 + 'Please Try Again!', mtInformation, [mbOk], 0); exit; end; end; Once you are connected to the server, you can use either the TClientSocket's SendText or SendStream method to send the data to the server. For example: procedure Send; begin // Checking whether the socket connection is ready or not // If not , the error handling part of the TClientSocket will be // activated if csClientSocket.Active then begin // Sending the text through the socket connection csClientSocket.Socket.SendText('The string to send'); // Setting a flag to wait until the server sends the response back dmDataModule.FWaiting := True; while dmDataModule.FWaiting then Application.ProcessMessages; end; end; ________________________________________________________________________ 4. DESIGNING 'SKINNED' DELPHI APPS By Charl Linssen <charl @ atomasoft.com> Hi there folks. I wrote this tiny tutorial for people who are trying to write a skinned Delphi application. Why would you want to do this? Well, take WinAmp for instance, an MP3 player most of us know. The program is 100% skinned, and although it is probably written in C/C++ you can tell right away that there are no TButtons on the main form. Obviously, this is done because it looks great. But unfortunately, it also greatly increases file (and download) size. Therefore, you should only skin your app when it really adds up to the program. For every button and label and anything else, you have to make an image. Then another one for the OnClick, and perhaps yet another one for the OnMouseMove. Again, when not necessary, don't skin your app. But if you think 'blah blah let's get to the code' I won't bother you with advice any more. If you want to skin your app, you may also want to get rid of Windows standard rectangular window shape. That can be done rather easily by specifying a number of points (X,Y) and inserting the SetWindowRgn procedure: const RgnPoints : array[1..12] of TPoint = ((X:9;Y:6), (X:177;Y:6), (X:184;Y:13), (X:9;Y:49),(X:4;Y:43), (X:4;Y:11)); { Just a sample: this will probably look like hell :) } var Rgn : HRGN; begin Rgn := CreatePolygonRgn(RgnPoints, High(RgnPoints), ALTERNATE); SetWindowRgn(Handle, Rgn, True); end; Now, this code shouldn't be hard to understand. For every RgnPoint a line is drawn from RgnPoints[I-1] to RgnPoints[I]. From the last coordinate -in this case (4,11)- a line is drawn back to the first one (9,6). This may be a bit hard to understand, but just copy it and paste the last part in the FormCreate event (the RgnPoints array should be where Form1 is declared). Back to the actual skinning =========================== When (if) I skin an app, I simply put a TImage on the form with the background image, and then place all components on it. You may also want to consider a TImage, on top of it a TPanel, and on top of the panel all your components. This may come in hand with some things. Of course, when doing this, you won't be able to resize the form. But that can also be fixed easily. You just take separate pictures for the top left, the top right, bottom left and bottom right. Then you use the OnPaint event to draw all necessary elements between those images. Well, that's it for this time folks, I hope I can find the time to write more useful tutorials. If you have any questions about this one, feel free to mail me at <charl @ atomasoft.com>. Also, be sure to visit my site at http://www.FutureAI.com, it's about Artificial Intelligence. Cya! // Charl ________________________________________________________________________ 5.
