Question

I have a button, with an event onClick(), when I press down the button it Should add in two different tables (Seuil and Notifier). This is My code

Button Code :

//Here I instanciate my Connexion class Where I fill the data table and the data set

con.seConnecter();

//Here I verify if the table Seuil has already a similar record 

if (con.verifierExistance("Seuil", "idSerieMateriel", DropDownList1.selectedItem) &&
    con.verifierExistance("Seuil", "idMagasin", DropDownList2.selectedItem))
{

// If exist, do an update

    con.charger("update Seuil set qteMin ='" + txtQteMin.Text + "', qteMax ='" + txtQteMax.Text + "' where idMagasin='"+DropDownList1.selectedItem+"' and idSerieMateriel ='" + DropDownList2.selectedItem + "'", true);
}
else
{
    //if not Insert a new one
    con.charger("insert into Seuil values('DropDownList1.selectedItem', 'DropDownList2.selectedItem', '" + txtQteMin.Text + "', '" + txtQteMax.Text + "')", true);
}

//and in the end, it should add a row in the table 'notifier'
con.charger("insert into Notifier(matricule, qteMin, qteMax, typeMateriel, Serie, idMagasin, date) values('10', '" + txtQteMin.Text + "', '" + txtQteMax.Text + "', '" + cmbType.SelectedItem + "', '" + cmbSerie.SelectedItem + "', '1', '" + DateTime.Today + "')", true);

My class connexion

public void charger(string query, bool variable)
{
    commande = new SqlCommand(query, connexion);
    dataAdapter = new SqlDataAdapter(commande);
    dataSet = new DataSet();
    dataAdapter.Fill(dataSet);
    if (variable)
    {
        dataTable = dataSet.Tables[0];
    }
}

The function that verifies the existance of a similar code

public Boolean verifierExistance(string tableName, string primaryKey, string textBoxValue)
{
    charger("select * from " + tableName+ " where " + primaryKey+ " ='" + textBoxValue+ "'", true);
    if (dataTable.Rows.Count == 0)
    {
        return false;
    }
    else
    {
        return true;
    }
}

And the error

System.IndexOutOfRangeException: Cannot find table 0.

Ligne 61 :         if (variable)
Ligne 62 :         {

Ligne 63 :             dataTable = dataSet.Tables[0];
Ligne 64 :         }
Ligne 65 :     }

Answer 1

The problem is you cant get a dataset when you update or insert a row in db, you will get it only when you select data,

In this case your

dataAdapter.Fill(dataSet);

in

charger

function will be empty

hence it throws a error when you try to access the 1st table at 0th index

Answer 2

I found it, I just don't know why I didn't pay attention to it, the probleme was a small 'true' that had to be changed with a 'false' in my query

con.charger("insert into Seuil values('DropDownList1.selectedItem', 'DropDownList2.selectedItem', '" + txtQteMin.Text + "', '" + txtQteMax.Text + "')", FALSE);

Thank you very much for your time, help and effort ^_^ <3
