View 2 Replieshow if it possible to publish program straight to wep. I asked before another question about publishing and making setup files, that worked well. But now I have finished other of my programs and I want to know can I somehow add it straight to wep site? I have now used suntuubi.com as own wep site, it's not the best but its free :) And I have usually posted a link to download setup from mediafire (or some other) but can I run that program from my page without any downloads? I made that program with windows forms application, do I need to use wbf broswer application? ( if so, can I somehow fastly switch it without making everything again?) And one more, if it is possible in some other wep site than suntuubi.com can you recommend it?

I've spent days trying to use XML to do this but to no avail mainly cos my classes use ArrayLists as properties and it gets a bit beyond me. I've been told that ArrayLists were not the best choice for this and would be prepared to change my design if need be if I thought the end to this problem was in sight.

I am trying to verify that a string contains nothing but known values. In this case, I need to make sure it contains only "Shift", "Control", or "Alt", but not necessarily all of those. For example, these should be true: "Shift + P", "Shift + Control + H", "Alt + U; but these should not: "Other + P", "Shift + Fake + Y", "Unknown + Shift + E" etc.This is the code I tried to use:
If Not shortcut.Contains("Shift") Or Not shortcut.Contains("Control") Or Not shortcut.Contains("Alt") Then
MessageBox.Show("Invalid")
End If
I'm having difficulty wrapping my head around the needed logic to do this. I'm assuming there's a logic operator that can do this?
