Hello everybody

How can i retrieve the full username(displayname) from the active directory with VFP8.0

I get the current user by doing the following code
* user und standardmessage ???
DECLARE INTEGER GetUserName in WIN32API String @,Integer @
LOCAL lcUser
lcUser=SPACE(40)
GetUserName(@lcUser,20)
p_user=STRTRAN(lcUser,CHR(0),'')
p_user = ALLTRIM(UPPER(p_user))
p_messagetitel="Hello " + p_user + "! Just a moment !??"
*end user und standardmessage ???

Now i need the full username(=displayname) of the current user from the AD ??
p_user = ameier
p_displayname = "Anton Meier"

I don't know how to code this.
Any help welcomed.

Best regards
Albert
