Para se desenvolver sistemas utilizando o Intraweb necessrio saber alumascoisas, principalmente, sobre onde ficar esta aplica$%o, isto quer dizer, qualser o sistema operacional e qual ser o servidor de web dispon'vel para seutilizar.

9endo estas respostas necessrio saber a quais sistemas operacionais e aquais servidores de web o Intraweb fornece suporte de desenvolvimento.

9his update looMs at what issues need to borne in mind when usin *elphi to create:eb applications for #pache runnin on :indows. >ortunatel/, thins are a bit simplerhere than the/ are in ;inu0 a welcome relief-. 9his article should be considered anupdate to the oriinal article rather than standalone, so if /ou are unfamiliar with#pache and *6&s or shared modules- I recommend /ou have a read of it. 3ust inorean/ references to ;inu0 issues alon the wa/, particularl/ about recompilin #pache

there is no need to do this with the :indows version of #pache-.

our first question miht be to asM wh/ we should bother looMin at #pache an/wa/.#fter all, #pache on :indows is certainl/ not as well established as #pache on ;inu0, orII6 on :indows. :ell, /ou should consider that whilst :indows AWWW Professional shipswith a cop/ of II6, it onl/ has a !W user limit. If /ou want /our :eb server to worM well/ou will need to uprade to :indows AWWW 6erver and et the appropriate additionallicensin.

1ore thins in #pacheXs favour include the fact that it is completel/ free and has its fullsource code freel/ available for download. #dditionall/, it is straihtforward toconfiure throuh one te0tual confiuration file and has updates made to its sourcecode tree far more frequentl/ than II6. &n top of this, the main source code base isevidentl/ well established, iven the mass acceptance of #pache on Internet serversprimaril/ ni0 s/stems-, and the documentation states that it can even load up I6#PI*;;s.

9here is also the fact that the basic loic /ou place in a :eb)roMer or :eb6napapplication is much the same no matter what :eb server protocol /ou are taretin,so /ou can easil/ taret #pache :eb server from /our e0istin :eb server applicationsb/ creatin a new pro8ect file set up appropriatel/. # minimal amount of worM canresult in another :eb server platform that /ou can sa/ that /ou taret.

#dditionall/, it is 8ust at home on :indows V", VS or 1e as it is under :indows

(ote:*elphi Y has onl/ been certified for use with #pache up to version A.W.OV as thatwas the most current version available when it was sent to manufacturin. #pacheA.W.LW introduces more chanes that breaM the *elphi support and requirinmodifications to the support units. Nowever, all is not lost as unofficial patchinformationsupplied b/ a )orland enineer is available online that allows #pacheA.W.LW and hiher to be used with shared modules written in *elphi.

igure E: elphi K "pache support

/li0 O was released 8ust before *elphi Y indeed *elphi Y includes a cop/ of the *elphilanuae version of /li0 O in the bo0-, but #pache A support did not maMe it into thatproduct. 9his ma/ happen with an update pacM, but in the meantime /ou could alwa/str/ ZborrowinZ the pertinent #pache A source files from /our cop/ of *elphi Y andusin those instead of the #pache ! files in /our shared module pro8ect. 9he #pache

source files are located in [*E;PNI-\6ource\Internet, where [*E;PNI- is the main*elphi installation director/.

9he units used in #pache ! applications are(

#pache#pp.pas, used in the pro8ect source #pacheN99P.pas, used b/ #pache#pp N99P*.pas, used b/ #pache#pp and #pacheN99P

9he files used in #pache A applications are(

#pache9wo#pp.pas, used in the pro8ect source

#pache9woN99P.pas, used b/ #pache9wo#pp N99P*A.pas, used b/ #pache9wo#pp and #pache9woN99P

6o in theor/ /ou could cop/ the #pache A support files across to /our pro8ect director/and modif/ the pro8ect usesclause to use #pache9wo#pp instead of #pache#pp.

Installing "pache

)efore writin an/ #pache shared modules, /ou need to et hold of #pache and installit. ou can et a ]IP file containin the source code from httpd.apache.orDdistDhttpd,but that requires /ou to have 2isual 5^^ to compile it. Instead, I recommend /ou et

the precompiled version without source code fromhttpd.apache.orDdistDhttpdDbinariesDwinOA. I downloaded version !.O.AW,apache_!.O.AWFwinOAFno_srcFrA.msi, which is a :indows Installer file that can be usedto install #pache. 5learl/ this means /ou need the :indows Installer on /our machine,but if /ou havenXt /ou can download it from the 1icrosoft :eb site.

9he last time I checMed there were two main versions of #pache available, one is aversion !.0 #pache !.O.A- and one is a version A.0 #pache A.W.LW-. #s discussedearlier, if /ou are usin *elphi /ou must download the !.0 version as support for A.0onl/ arrives in *elphi Y.

Prerequisites

To run the example in this tutorial you'll need the following:

IntraWeb 5.1 in Application Mode (to get an evaluation copy of IntraWeb, please go to the Atozed

Software website -http://www.atozedsoftware.com)

One of the following : Delphi (5, 6 or 7), Kylix (2 or 3), C++ Builder (5 or 6) or JBuilder. Visual

Studio.NET is currently under development

Approximately 20 minutes of your time (installation time not included)

*reating a new application

his application is built using IntraWeb Borland Edition and application mode.

The first step is to create a new IntraWeb application. To do this select the File menu, then New

(Select New, not New Application, etc), then Other. A "New Items" dialog will appear. Select the

"IntraWeb" tab. It should look like this:

IntraWeb New Dialog

Using this dialog you can start a new IntraWeb application or add new IntraWeb forms to your

existing applications.

After selecting "IntraWeb Application Wizard", the wizard will launch and you'll be presented with
http://www.atozedsoftware.com/http://www.atozedsoftware.com/http://www.atozedsoftware.com/


40/69

the following dialog:

The IntraWeb Application Wizard

For this application we'll select "StandAlone Application". This will produce a self contained

executable, that will be the only thing on the server side that you'll need to run your application. You

do not need a web server of any kind.

Notice the other available options: you could make your application a Windows service, and ISAPI

extensions for web servers that support ISAPI, like IIS and OmniHTTPD, and even an Apache

module.

The options in the right panel specify whether the application should have a DataModule by default,

if support for user sessions will be available, whether the HTML output should be 3.2 or 4.0 (default

is 4.0 unless you check the "Create Main form as 3.2" box) and if the ISAPIThreadPool unit should

be used (for the IIS server only).

Each new IntraWeb application consists of three modules:

1. Project1.dpr - This is the project file.

2. Unit1.pas and IWUnit.dfm - This is the main form of your application. You can change this by

editing the project file, or even have multiple main forms determined by an incoming HTTP variable.

3. ServerController.pas and ServerController.dfm - This is the server controller and used to

configure your IntraWeb application and create application level events. In a new application you


41/69

can leave all properties as default.

If you want, you can rename any of the files by doing a Save As from the File menu.

Implementing +Nello 0orld+

If you have worked with other web technologies you are probably gearing up for a very big tutorial

on simply how to implement even the simplistic "Hello World". I hope we will not disappoint you, but

this tutorial will be very short, but only because IntraWeb makes this so amazingly simple.

Open the main form of the application (Unit1). It will appear as a blank form like this:

Blank IntraWeb Form

You will quickly notice the form is blank. Do not worry - this is just like a new normal Delphiapplication when we create it. The main form is blank and we must implement our application.

Select the IntraWeb standard components tab (IW Standard tab) on the component palette as

shown here:


42/69

IntraWeb Standard Palette

In the standard palette you'll see the base components for web development. However, that's not

all. You an look in the other IntraWeb palettes to see components for database access, HTML 3.2

output, client side processing etc. For a complete reference of IntraWeb components, please see

the IntraWeb Reference file. You can download this file from the Atozed Software website.

Select the TIWLabel and then place it on the form. It should look something like this:

Main form with label

Now just like a normal Delphi application use the property inspector to change the caption of the

label. Change the caption to "Hello World Wide Web!". You will notice that the label on the form
http://www.atozesoftware.com/http://www.atozesoftware.com/


43/69

updates itself to reflect this change:

Caption of the label has changed

Now all that is left to do is to run the application and test it.

Aunning the application

We have created this application as a stand alone application. What this means is that it will

execute completely stand alone and become its own web server. This is extremely useful fordebugging and testing, but it can also be deployed in this manner. Not only can it run stand alone,

but it can be installed as a service on Windows NT, Windows 2000 and Windows XP. Please see

the IntraWeb documentation for more information on this.

To test our application, simply run it as you would any other Delphi application. You will then see a

dialog similar to this:


44/69

IntraWeb Stand Alone Information Dialog

This is a dialog to assist you in testing and debugging. To test it in the browser click Run then

Execute or press the F9 key.

This will launch your default browser with the start URL for the application:

The browser window


45/69

*onclusion

Congratulations! You have just created a web application! All of this with no HTML, and it was just

like a normal Delphi application was it not?

Now you might say "Well that is fine and dandy, but what about input? You are just showing us

limited pieces and there are hidden gotchas." Trust me, there are no such "gotchas" waiting for you.

IntraWeb handles input just like any other Delphi application. Want to handle a button? Define the

OnClick event, that is it. Want to read the value of a text box? Read its text property.

But please, do not simply take our word for it:

See the next tutorial - User Input.

Downloadthe fully functional evaluation edition and look at the demos.

Introduction

In this tutorial you'll learn how to use multiple forms, how to handle user input and how to use

sessions.

In order to understand and run the example in this tutorial you should read the "Hello World" tutorial

first.

What is Next

This application is built using IntraWeb's application mode.

The last tutorial was very basic and designed to simply show you how easy it is to get an IntraWeb

application up and running. As you will soon see the code used is still standard Delphi code. We

challenge you to try even something this simple with any other web development tool. Other

development tools require you to set up adaptors, bindings, or handle the HTTP variables your self.

Not IntraWeb, IntraWeb is truly componentized.

For this demo, we will continue by modifiying our "Hello World" application built in the Hello World

demo. If you have not created this project yet, you will need it for this demo.

Changes to the Main Form

Set the form's Title property to "What is your name?". This will be displayed as the page title

when shown in the browser.

Change the label's Caption to read "What is your name?"

Add a TIWEdit to the form.

Set the Text property to be blank.

Set the Name property to editName.

Add a TIWButton to the form.

Set the Caption property to "Talk to me!".

Your form should now look something like this:

New Main Form


47/69

Handling a Button Click

If you have never worked with web development tools before, this next step will not seem like magic

for you as you will think, "This is the way it should work, no?". However if you have worked with

other web development tools, you will now really begin to see where IntraWeb is different.

To handle a button click in IntraWeb, it is just like a normal Delphi application. Simply create a

OnClick event for your button and add code. To do this, double click on the button. Delphi will

create a shell event for you similar to this:

Add the following code to the event:


48/69

Testing the Application

Run the application as we did in the previous demo, and press F9 again after the debug windowappears to launch the browser. The browser should appear like this:

In Internet Explorer

Notice the browser has picked up on the page title as set in the form's title property.

Enter your name in the edit box and press the button. The browser will respond like this:

Hello !

Multiple Forms

ust to show you that there are no hidden gotchas with IntraWeb, let's continue on and show you

how easy it is to do multiple forms with IntraWeb.

Select New | Other from the File menu, and select the IntraWeb tab. This time select New Form and

click OK:

Creating a New IntraWeb Form


51/69

The following dialog will appear, allowing you to select the form type:

New Form Wizard

This dialog allows you to select whether you want a Page Mode form, or an Application Mode form.

For each of those, the HTML type is also selectable, so you can chose to produce a HTML 3.2 form

or a HTML 4.0 form. For this tutorial we'll chose "Application Form", which will produce a HTML 4.0

application mode form. For a detailed explanation of page mode and application mode, please refer


52/69

to the IntraWeb Manual.

You will now have a new blank form again:

New Blank Form

Using the property inspector, apply the following changes:

Change the form Name property to formHello.

Add a TIWLabel

Set the Name property to lablHello.

For the Font property:

Bold = True

Size = 24

Name = Arial Narrow

Color = clRed

AutoSize = False. We will be adjusting the text at run time and thus will be manually


53/69

adjusting the width.

Width = 300

Add a TIWLink

Set the Caption property to Close.

Create an OnClick event by double clicking on the TIWLink.

Add the following statement to the event:

Your form should now look something like this:

Now let's move back to our main form. Change the button click event to read as follows:


54/69

Let's also add one more TIWButton to the main form. Set its caption to Done, and create an

OnClick event to read:

Now run the application and press F9 when the debug window appears. The browser should appear

similar to this:


55/69

Enter your name and click the Talk to Me! button. The browser now displays your second form like

this:

Notice that even the browser caption has been updated with your name. Click the Close link. The

browser will return to your main form:


56/69

Now click the Done button. The browser will terminate the application and display this message:


57/69

Wow! Multiple forms, transparent user input, automatic session management, the works! And we

still have not written a single line of HTML or Javascript. Does it get better? Yes it does, but you will

need to see for yourself by trying IntraWeb.

Code Examination


58/69

Faster Web Development

If you are a Delphi shop, there is no doubt your programmers can be up and running with IntraWeb

in a matter of minutes while continuing to use their existing skills. You can develop web applications

in days instead of months, and you can take on web projects previously deemed impossible or too

time consuming. Now, can you honestly say that about any other web development tool?

Conclusion

This tutorial took the next step and demonstrated the ease of handling user input and managing

multiple forms.However IntraWeb is far more powerful and has many more features than what has

been demonstrated here. To see the full power of IntraWeb you need to look at the included demos

and better yet, write your own application.

The evaluation version is fully functional, so what are you waiting for?

Abstract:This article explains a way to be able to use visual form inheritance with IntraWeb(5.1). Something that normally is not woring.

Introduction

When I started &ith m' first real appli"ation in IntraWeb( I &anted to ma$e a "onsistent la'out

throu)h out m' appli"ation. Sin"e &ith IntraWeb 'ou "an ma$e a &eb appli"ation *ust li$e anormal +elphi appli"ation, m' first thou)ht &as, *vi)ual, form inheritance-FI. So I startedhappil' pro)rammin) ma$in) a baseform as a parent for all m' other forms( puttin) on it a titlebar( and started inheritin) from it. nd it &or$ed, I had the title bar on all m' forms1

ut after I started pro)rammin) reall' fun"tional forms( I soon also &anted to "han)esomethin) about m' baseform( ma$e the la'out a bit ni"er and better fittin) &ith the forms I&as ma$in). nd then it happened, I had added somethin) to m' baseform( "ompiled theappli"ation and it *ust )ave an e%"eption, Control +IWutton1+ ha) no parent 'indo'. Ihadnt "han)ed an'thin) reall'( e%"ept enhan"in) m' baseform, and there &asnt even aIWutton on m' baseform( it &as on m' mainform1 Well after a little debu))in)( I loo$ed atthe IntraWeb ne&s)roups and its &ebsite and soon found the ans&er, IntraWeb doesnt

support vi)ualform inheritan"e. ou "an use inherited "ode( but 'ou "ant inherit the visualla'out...

4inding the problem...

Sin"e I am a stubborn person -I &anted to use visual form inheritan"e1( and in m' opinionproblems are there to be solved( I started di))in) deeper in the problem. With the help of+elphis 7 "ode -one of the thin)s I love most about +elphi, 'ou "an al&a's loo$ at thesour"e1 I soon found out in &hi"h part I had to sear"h for the problem, the SetN#rder3o)itionmethod of TControl. When 'ou add "ontrols to a form 'ou have inherited from -the baseformthe orderin) of the "ontrols on 'our des"endant forms -in m' "ase the 8ainform "han)es. ou"an see this orderin) &hen 'ou loo$ at the dfm file of a des"endant form, 'ou see numbers inbra"$ets : after the "ontrols. hese numbers tell +elphi in &hi"h order the "ontrols appear. Inthis Set;!rder#osition method there is a "all to alid#arentForm -found in Forms.pas thatreturns the parent form of the "urrent "ontrol if that parent forms is a des"endant ofustomForm. nd that &as the problem, a IWppForm is not a des"endant ofustomForm1

...and trHing to fi> it.

Well onl' findin) the problem doesnt solve it( I needed to find a &a' to fi% it. 8' first thou)ht&as, I &anted that orland had made alid#arentForm a virtual prote"ted method of ontrol(so an'one "ould override it( and the )u's from IntraWeb "ould have made a spe"ial versionthat &or$ed &ith IntraWeb forms. ut sin"e that &asnt the "ase( I had to )o one level up to theSet;!rder#osition method. nd found out that that one is private to ontrol( so no "han"e of

overridin) that. (!.T.W. If that one coul" have be overri""en it woul" have also meant that itha" to be "one in TIW!ase#ontrol$ an" I woul" not be able to "o that.)So I needed to )o upone level, the "aller of Set;!rder#osition &hi"h &as in this "ase the Sethild!rder method ofWinontrol( &here this Winontrol &as a"tuall' m' 8ainform. nd the ni"e ne&s &as thatSethild!rder of Winontrol "ould be overridden1


61/69

Seein) that I needed to override Sethild!rder of m' 8ainform( and sin"e that one inheritedfrom m' baseform, I put m' implementation of Sethild!rder in m' baseform. 8'implementation loo$ed as follo&s,

So if the hild is a IWaseontrol I "all a spe"ial implementation of Set;!rder#osition else I*ust "all the inherited version. hat spe"ial implementation of Set;!rder#osition I put in a "lass"alled IWaseontrol


62/69

TrHing it out

nd no& the e%"itement be)ins, does it all &or$@ So I started runnin) m' &eb appli"ation, andit )ave no error1 o reall' test it I made a lot of "han)es to m' baseform( I made "han)es to m'mainform and other forms, and it $ept on &or$in). I also "han)ed the order of the "ontrols onm' baseform and mainform b' sele"tin) the "ontrol and ri)htA"li"$( "hoose ontrol AB sent toba"$ and brin) to front( sin"e that a"tuall' manipulates that ;A!rderin)( but it $ept &or$in).

Conclu)ion

So this finishes m' solution for usin) visual form inheritan"e -FI &ith IntraWeb 5.-.2C in+elphi D in appli"ation mode. We are usin) it for >uite some time no&( and havent run into an'bu)s. ou "an )et the sour"e of this solution( in"ludin) a small test pro*e"t at "ode"entral.

In"luded in that sour"e is a IWaseFIForm -in IWaseFIForm.pas that 'ou "an use toinherited from. !f "ourse 'ou "an also *ust "op' the "ode from that form to 'our o&n baseform.

Eemember one thin) &hen usin) this solution, the developer of IntraWeb doesnt support FI(so I have no idea if it &ill &or$ for other versions of IntraWeb nor if it &ill &or$ &ith pa)emode1 Ialso havent tested this "ode &ith IntraWeb in +elphi 5 or 6( but a >ui"$ s"an of the relevantsour"e "ode of those implementations of ontrol doesnt sho& an' possible problems, so *usttr' it out.
