BlitzMax Forums/BlitzMax Programming/Get XP Username

Is it possible or is there a command available to find out the name of current user that is logged into Windows XP and running your BlitzMax App?

youll have to port it though....

This should do it...

' Function stuff...

Global GetUserName (buff:Byte Ptr, size:Byte Ptr)

adv32 = LoadLibraryA ("advapi32.dll")
If Not adv32 Notify "Can't open advapi32.dll!"; End

GetUserName = GetProcAddress (adv32, "GetUserNameA")
If Not GetUserName Notify "Can't find GetUserNameA function!"; End




' Test...

Local name:Byte [256]
Local size = 256

If GetUserName (name, Varptr (size))
	Print StringFromArray (name)
EndIf





' Conversion to/from C strings...

Function ArrayFromString:Byte [] (source$)
	Local newarray:Byte [Len (source$)]
	MemCopy (newarray, source.ToCString (), Len (source$))
	Return newarray
End Function

Function StringFromArray$ (source:Byte [])
	Return String.FromCString (source)
End Function

Or a one-liner:

Print getenv_("username")


Windows automatically keeps a bunch of environment variables that can be read by any program. This includes username as mentioned above, but also other useful information such as:

- installation directory for windows ("windir")
- your personal directory ("userprofile")
- the location of your program file directory ("programfiles")
and a bunch of other info. To see the full list, open a DOS command prompt (cmd.exe), and simply type: set

Got one that's cross-platform?

name$=Input("What's your name?")

Sorry... couldn't resist :)

Cross platform...
system_ "who am i"

This will print the username under unix/Mac os.Parse out the other info.To ensure cross platform ability a comparison should do the job:

@all thank you very much,

I tried the easiest solution

Print getenv_("username")


and it works fine for me. If the getenv_("username") commands results an empty string I will prompt the user name via a requester. I hope this will keep my source cross platfrom compatible.
