CreateProcessAsUser is ignoring wshowwindow's value

Hi, the code below works for me (both in 2000 and XP)... Maybe the problem is that you're passing eStyle parameter as enSW structure instead of integer/long?

Private Const LOGON_WITH_PROFILE = &H1&
Private Const LOGON_NETCREDENTIALS_ONLY = &H2&
Private Const CREATE_DEFAULT_ERROR_MODE = &H4000000
Private Const CREATE_NEW_CONSOLE = &H10&
Private Const CREATE_NEW_PROCESS_GROUP = &H200&
Private Const CREATE_SEPARATE_WOW_VDM = &H800&
Private Const CREATE_SUSPENDED = &H4&
Private Const CREATE_UNICODE_ENVIRONMENT = &H400&
Private Const ABOVE_NORMAL_PRIORITY_CLASS = &H8000&
Private Const BELOW_NORMAL_PRIORITY_CLASS = &H4000&
Private Const HIGH_PRIORITY_CLASS = &H80&
Private Const IDLE_PRIORITY_CLASS = &H40&
Private Const NORMAL_PRIORITY_CLASS = &H20&
Private Const REALTIME_PRIORITY_CLASS = &H100&
Private Const STARTF_USESHOWWINDOW = &H1
Private Const SW_MAXIMIZE = 3

Private Type PROCESS_INFORMATION

Hi Darko.
I tryed your code as well (on more than 1 macines) and unfortunately it seems to have the same problem.
Do u have an idea?
