OK!
Thank you. I got it.
I have to get a button to the form and then set the "AcceptButton" property to use "button1" of the form - not the button property.
Then i can use Enter-key triggering the "button1" button.
I don´t really want a extra button in my form, and i think it´s a little crazy, but i works. No other methods work for me.

[code]
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace enterkey
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
string sometext;
sometext = textBox1.Text;
MessageBox.Show("You Wrote " + sometext);

//Compare entered text to a string

if(sometext=="hello world")
MessageBox.Show("string match");
else
MessageBox.Show("string mismatch");
}

}
}

]/code]

I get no respons at all.
Nothing is happening.
No error message.

If i use textBox1_TextChanged method i get a respons
in this example the key a is pressed.
What i want to do is write some text in textBox1 and press enter,
and then treat the text in textBox1 as a string.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace enterkey
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();


        }

        private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
                MessageBox.Show("enter is pressed");
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            if(textBox1.Text == "a")
                MessageBox.Show("a is pressed");
        }
 

    }
}

Why would i need two progressbars.
Well i figured it out by myself.
This is the correct code (part of the modified code):

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            // Set Minimum to 0 to represent the first row beeing processed.
            progressBar1.Minimum = 0;
            // Set the initial value of the ProgressBar.
            progressBar1.Value = 0;
            // Set the Step property to a value of 1 to represent each row beeing processed.
            progressBar1.Step = 1;


             // Calculate number of rows.
            System.Int32 calculaterows = dataGridViewDump.Rows.Count;

            // Set Maximum to the total number of rows beeing processed.
            progressBar1.Maximum = calculaterows-1;        
        }

        void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            
            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;

            xlApp = new Excel.Application();

            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            int i = 0;
            int j = 0;

                for (j = 0; j <= dataGridViewDump.ColumnCount - 1; j++)
                {
                    xlWorkSheet.Cells[1, j + 1] = dataGridViewDump.Columns[j].Name;
                }

                for (i = 0; i <= dataGridViewDump.RowCount - 1; i++)
                {
                    for (j = 0; j <= dataGridViewDump.ColumnCount - 1; j++)
                    {
                        DataGridViewCell cell = dataGridViewDump[j, i];
                        xlWorkSheet.Cells[i + 2, j + 1] = cell.Value;

                        backgroundWorker1.ReportProgress(i);
                    }
                }

 
            System.Threading.Thread.Sleep(1000);

            MessageBox.Show("Excel file created at desktop as dbasedump.xls");

        }
     }

No other problems.

How do i report progress of i and j?
