Show us what you tried first.
P.S Also read about a neat trick called data binding. It allows you to achieve all that without breaking any bones.

insertAlias

I'm not sure what your goal is, it was a bit hard to understand...but we have two articles that might help you in using a database:

Il try to explain it again i have a databse in sql like this for example

Firstname Lastname Age

Jan Jansen 44
0 1 2

now i have 3 records with a number on it in sql starts with 0 so it looks like this record 0 is Firstname and so on

now i whanne load the name Jan into an Array someting like this

Expand|Select|Wrap|Line Numbers

 
txtFirstname.Text = OfferteArray[0];

txtLastname.Text = OfferteArray[1];

txtAge.Text = OfferteArray[2]

so i whant that the OfferteArray[0] has loaded the value Jan from my database and strored it in the txtbox txtFirstname.Text

Hope you understand me now Tnx for reply

OK. One last time.

What you are trying to do with those arrays all over the place is very Fortranesque.
Better use object oriented programming these days. Simply create a small class that represents your table structure. You then read data row by row creating objects of that class type with the data and store those objects in ONE ArrayList where you can then manipulate them at your own leisure.

P.S Several useful hints have already been given to you for your problem but you seem to be ignoring them and starting off multiple threads for the same problem.

P.P.S Remember that double posting is not allowed in these forums.

P.P.P.S: this is really the last time!

Hey i think i got 1 step farther becase now i get an differnt error and if i leave the txt OfferteArray in the code he will still runn the application but i get an error later on in a method

Dont now if you still whanne try to help but i need to try i cant do it myself XD

the error message i get now is

No overload for method 'GetOfferteGegevens' takes '1' arguments

And yes i first lookd on the internet for solutions but cudent find any useful 1
Weird thing is that the error message is differtn from the code error becase the bleu line is under dbConn

here is the code hope somone is interested enouf to try to help

Expand|Select|Wrap|Line Numbers

         #region Invullen van de tekstvelden uit Database

        public void Vullen_tekstvelden(string[] OfferteArray, bool nieuw)

        {

            localhost1.dbConnection dbConn = new localhost1.dbConnection();

            OfferteArray = dbConn.GetOfferteGegevens(txtNoteID.Text);

            txtNoteID.Text = OfferteArray[0];

            txtBTW.Text = "25";

            txtOfferteNr.Text = OfferteArray[1];

            txtDatum.Text = Functions.DateToNL(OfferteArray[2]);

            txtDebNr.Text = OfferteArray[3];

            txtKlantNaam.Text = OfferteArray[4];

            txtContactpersoon.Text = OfferteArray[5];

            txtOmschrijving.Text = OfferteArray[6];

            txtOrderNr.Text = OfferteArray[7];

error is rule number 5 i think on the dbConn.GetOfferteGegevens lap of code
