Question

If have an array of Bytes in visual basic:

Dim data() As Byte = {0, 128, 0, 4, 9, 9, 32, 0, 0, 0, 0, 0, 0, 0, 0}

Is there a quick and easy way to insert two data values to the front of this array, and knock off the last two values?

Dim data() As Byte = {128, 128, 0, 128, 0, 4, 9, 9, 32, 0, 0, 0, 0, 0, 0}

Answer 1

Yes. First you need to move all of the existing values up 2 places in your array. Doing so will overwrite the last 2 values. You’ll then want to set the first two values of your array.

'Move data up 2 spots.  This needs to be done in reverse order so we don't lose any data
For i as Integer = data.Length - 1 To 2 Step -1
    data(i) = data(i - 2)
End

'Assign the new values
data(0) = 128
data(1) = 128
