Tried Ruchi's answer because I was curious too and works well. Only comment I have is that if you want to compare it to what you get at the command prompt by typing &quot;dir&quot;, use the hex function:<br />
<br />
Call MsgBox(Hex(GetSerialNumber<wbr />(&quot;C:\&quot;)))

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
