so i was trying to get the the room name off of a gui i made using treeviewitems and for some reason $selectedRoom == 0 and $selectedRoom <> 0. i dont get it please explain

$selectedRoom = GUICtrlRead(GUICtrlRead($TreeView1), 1)
ConsoleWrite($selectedRoom&@CRLF); returns room name, which is never == to 0
If $selectedRoom <> 0 Then
GUIDelete($Form1)
_joinRoom($selectedRoom)
EndIf

this should work but for some reason it tells me that the room name is <> to 0, but it fails to execute the code correctly

oh and since theres a huge no game policy im making the game thats why i needed this code.

When you compare a string to a number the string is converted to a number, if it's not a numeric string, it gets converted to zero.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
