Small application in Delphi

Hi Rocky, yes that's fine, it works, thank you.

I am sorry, sir.

Yes, you can use SQL queries, look into the methods of the objects available in your Delphi 5.

Hello,

What kind of program would you like to create? Which version of Delphi are you using?

So, sign up on the site, it will allow us to exchange information, etc.

Delphi 5 is now outdated, the new free version is called Turbo Delphi Explorer, that's the one I have.

You can see here: https://downloads.embarcadero.com/free/turbo

Turbo Delphi Explorer
Free Download, Full Product, French

You need to sign up, you will receive the license by e-mail.

It installs on Windows XP

By "bar," you mean "toolbar" with images, I suppose? The component to use is TToolbar (I don’t know if it exists in version 5). But it's easy, you add this component, you can add buttons on it, set the button images. And then you just have to define what happens when you click on a button.

I hope this gives you a lead. If I were you, I would try to download the new version of Delphi.

Well, assuming TToolbar is available.

A default application: create a new "VCL Application" project (if that's what it's called in Delphi 5).

On your form, drag a TToolbar to add it

You also add a TImageList for the image list.

- Right-click on the TImageList in your form to edit and add a list of icons.

- Click on the TToolbar you just added. In the properties -> Link, you choose your image list (e.g., ImageList1) in Images

- Now, if you right-click on the TToolbar you just added, you can select "New button". In the properties of this button, you can then choose the ImageIndex that corresponds to the image number in your image list.

For example, if ImageIndex is set to 0, it's the first image you added to the list. Do the same for all your buttons.

If you double-click on a button on your toolbar, you can edit the code that will run when the button is clicked.

You will have a toolbar with buttons that have images.

I'm not sure if I explained myself well, but it's sometimes difficult to explain remotely like this! LOL

Have you been imposed Delphi 5? Because it must be quite old by now. Today you have some more sophisticated versions. But in any case, if you are starting out in programming, Delphi is a good language, as well as Visual Basic, etc.

We are required to work with Delphi 5, but it is our teachers who are asking us to do this. I would prefer to use another version, but it is not our decision.

Thank you very much, sir, it's very kind of you.

Salut, pour faire fonctionner les boutons de ta seconde forme (comme "AJOUTER", "RECHERCHER" et "SUPPRIMER"), tu dois écrire des procédures associées à chaque bouton. Voici un exemple de la façon dont tu peux procéder :

1. **AJOUTER un concurrent** :
- Crée un bouton pour ajouter un concurrent et associe-lui une procédure. Dans cette procédure, utilise les commandes pour insérer un nouvel enregistrement dans ta base de données. Par exemple :

```pascal
procedure TFormConcurrent.AjouterButtonClick(Sender: TObject);
begin
// Active la source de données
DataSource1.DataSet.Append;
// Remplis les champs nécessaires
DataSource1.DataSet.FieldByName('Nom').AsString := NomEdit.Text; // par exemple
DataSource1.DataSet.FieldByName('EquipeID').AsInteger := EquipeID; // selon ton modèle
DataSource1.DataSet.Post;
end;
```

2. **RECHERCHER un concurrent** :
- Pour rechercher, tu pourrais avoir un champ de texte pour saisir le nom du concurrent que tu souhaites trouver. Ensuite, crée une procédure pour filtrer les résultats :

```pascal
procedure TFormConcurrent.RechercherButtonClick(Sender: TObject);
begin
// Appliquer un filtre
DataSource1.DataSet.Filter := 'Nom = ' + QuotedStr(RechercheEdit.Text);
DataSource1.DataSet.Filtered := True;
end;
```

3. **SUPPRIMER un concurrent** :
- Pour supprimer un concurrent, tu peux ajouter une procédure qui supprime l'enregistrement sélectionné dans le `DBGrid` :

```pascal
procedure TFormConcurrent.SupprimerButtonClick(Sender: TObject);
begin
if not DataSource1.DataSet.IsEmpty then
begin
DataSource1.DataSet.Delete;
end;
end;
```

N'oublie pas de connecter ces procédures aux événements `OnClick` de tes boutons respectifs. Assure-toi également que les composants de ta base de données sont correctement configurés et que tu as bien ouvert la connexion à la base de données au moment de l'exécution. Cela devrait aider à faire fonctionner les boutons de ta forme Concurrent.

Hi, I think a Table object has an Insert method that you can use to add a record; otherwise, you can add a TDBNavigator object that has a "+" button to add.

Okay, I'll try, thanks.

Hello, last time you told me if I had in
Delphi 5 version the toolbar and you gave me steps
to insert an image as a background in my application.
I put the toolbar in my form and then in the object inspector,
in the PICTURE property, there are 3 ellipsis
I clicked then on load to choose the image I have to
insert then on ok but no result, I need your help please and thank you.

Thank you very much, that’s very kind.

Salut Rocky, j'ai un autre problème dans la propriété "connected" du composant "database". Lorsque je la mets à true, un message m'indique : "Erreur VIOLATION DE CLÉ". C'est quoi l'erreur, Rocky, s'il te plaît ?

Je voudrais savoir si quelqu'un a passé le test de programmation Delphi 6 en ligne, merci.

The best thing is that you use Delphi 5; it's more pedagogical and easier to understand.

You must start with Pascal language
well understand the concepts of: event, property, method
using Delphi components and little by little the bird builds its nest.
