Thanks again, Darthatron

If Len(txtR.Text) > 0 Then
    WriteHex ROMLocation, CLng("&H" & txtR.Text), Data
End If

The Len() Function checks the length of a String. It is used mostly for checking if you have any data held in a Variant. :D

The code "If Len(txtR.Text) > 0 Then" checks if the Length of the Data in the String is above 0. 'If' it is then it will do the code before 'End If'.
