Has anybody seen anything so stupid before?!?!?!

Hellow everybody!

I just have a simple but very stupid problem.. I'm writing a windows forms applicaton that generates random letters and put them in the form's label control.


 private void OnStart(object sender, EventArgs e)   //Event when you click on button 'Start'
 {
       //timer1.Start();
       String[] text=new String[4];
       for (int i = 0; i < 4; i++)
       {
              int number = GenerateNumber(1, 25);  //1 and 25 are max and min
              text[i] = GetLetter(number);                  //Function that returns a letter(type is String) and it works OK
              //MessageBox.Show("Letter: " + text[i]);
        }
        label1.Text = text[0]+text[1]+text[2]+text[3];     
 }


And here is the problem: In the label1 control i get four(4) letters which are the same(example: RRRR). Now if I only change this:

 private void OnStart(object sender, EventArgs e)   //Event when you click on button 'Start'
 {
       //timer1.Start();
       String[] text=new String[4];
       for (int i = 0; i < 4; i++)
       {
              int number = GenerateNumber(1, 25);  //1 and 25 are max and min
              text[i] = GetLetter(number);                  //Function that returns a letter(type is String) and it works OK
              MessageBox.Show("Letter: " + text[i]);  //I changed only this line
        }
        label1.Text = text[0]+text[1]+text[2]+text[3];     
 }



Now I get four different letters(in the label1 control) which is OK(example: RSJK). Has anybody have any idea
what my problem is???
