VS 2002 + bitshift the number by 8 bits
I am trying a FTP class from Microsoft website, and am using VS 2002, there is one section as seen below. It doesn't work.
I have tried this code on a different machine with VS 2003 and it works fine, so it looks like the code to muliple the number by 2 ot the power of 8 is working.
' Make this call in Visual Basic .NET 2002. You want to
' bitshift the number by 8 bits. In Visual Basic .NET 2002 you must
' multiply the number by 2 to the power of 8.
Dim port As Int32 = port = parts(4) * (2 ^ 8)
' Make this call and then comment out the previous line for Visual Basic .NET 2003.
'Dim port As Int32 = port = parts(4) << 8
Can i do this some other way.

What other way are you looking for?

I tried using Dim port As Int32 = parts(4) * (2 ^ 8) in VS 2002 and it comes back with a value of 0, it doesn't seem to work, because it doesnt return a valid port to connect to.

just stepped through and this is the value
parts(4) = 249
port = 249 * (2 ^ 8)
after the calculation port = 0
parts(4) = 249
port = 249 * (2 ^ 8)
after the calculation port = 0
If it's returning 0 (i.e. assigning 0 to port)... then your problem is in the parts(4) as far as i know... because that is a legit assignment.
So if this code works in VS 2003 and not in 2002.. there is something not working with the assignment to the parts array in the different versions of VS (that sounds confusing)

ok... will double check with mine

oh well however it works is all i need.
Thanks

No problem... maybe the second pair of eyes helped :P
Dim port As Int32 = parts(4) * (2 ^ 8)
That should be a valid line assuming the value in "parts(4)" is a number.
