I am relatively new to VB 2005 and have a form with a large number of buttons on it, 256 to be precise they are laid out in 8 rows of 32 and I need to change the colour of them based on a 32 digit binary number I have stored in a string. I will be getting a different binary string for each row of 32 so I thought a way of doing this would be to have a for next loop that goes around 8 times containing another which goes around 32 times. I was going to use mid on the string to find the value and if it was a 1 make the button green and if it is a 0 make it red I could bump the operation to the next line of buttons by adding 32 for the second 64 for the third and so on.

The problem is I can't work out how to select the button to change. I know if it is on the first time round the 8 and say the third time round the 32 then I need to select Button3 to change but I don't know how to code that bit

Can anybody help???

I haven't got much hair left to pull out!

If you create 8 sets of the event below for each group of buttons you only have to change the color eight times. For the example below I only added two buttons to the "Handles" info.
    Private Sub Button1_BackColorChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.BackColorChanged, Button2.BackColorChanged
        '* Change the color here
    End Sub

unfortunately I have to change individual buttons not blocks of buttons. This will be a graphical display of dynamic information.

You could make an array with the buttons’ names in it. when you find the button you are after numerically, get the name string out of the array, and use Me(<string here>).BackgroundColor = xxx. (You will, of course need to correct that syntax. Perhaps the syntax is like Me.Controls.Item(<string here>).BackgroundColor = xxx.)
