; Func _ShellExecuteEx($sCmd, $sParams = "", $sFolder = "", $sVerb = "", $iState = @SW_SHOWNORMAL,$bCloseProcessHandle=True)
;
; Parameters are the same as ShellExecute(), except for the addition of:
;
; $bCloseProcessHandle = If True (recommended unless planning on using Process Handles),
; then the Process Handle (if received) is closed
; If False, the Process Handle (if received) is returned - this can be used to do additional work with Processes
; Usage is mostly recommended for the _ShellExecuteExWait() function and/or getting exit code.
;
; Return is different from ShellExecute() in the following way:
; Success: @error = 0, and either the process ID (if $bCloseProcessHandle is True, and process ID received) is returned,
; or a 2-element array (if $bCloseProcessHandle is False):
; $array[0]=Process ID if new process started (and process handle+ID received),
; $array[1]=Process Handle if new process started (and process handle received)
; Failure: @error set and 0 is returned
; @error = 1 = parameters error
; @error = 2 = call failed (probably due to parameter error. can use _WinAPI_GetLastError())
;
; NOTE: Recommended to run on Windows 2000 or higher because:
; According to Microsoft at http://msdn2.microsoft.com/en-us/library/bb762154.aspx,
; Windows 95/98/Me: ShellExecuteEx is supported by the Microsoft Layer for Unicode (MSLU).
; To use this, you must add certain files to your application,
; as outlined in Microsoft Layer for Unicode on Windows Me/98/95 Systems.
; So it appears it will break on those machines without MSLU(?)
;
; Initial Code from MrCreatoR on AutoIt Forum Topic:: http://www.autoitscript.com/forum/index.php?showtopic=69868
; Enhancements/Modifications by: Ascend4nt
; (including process handle/ID extract & close-handle code, plus Unicode/path enhancements, & CoInitializeEx call)

; Per MSDN Documentation, the following call should be done prior to calling ShellExecuteEx:
; CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE) ; COINIT_APARTMENTTHREADED = 0x2,COINIT_DISABLE_OLE1DDE = 0x4
; Reason:
; "Because ShellExecuteEx can delegate execution to Shell extensions (data sources, context menu handlers, verb implementations)
; that are activated using Component Object Model (COM), COM should be initialized before ShellExecuteEx is called.
; Some Shell extensions require the COM single-threaded apartment (STA) type. In that case, COM should be initialized as shown here.
; There are certainly instances where ShellExecuteEx does not use one of these types of Shell extension and those instances would not
; require COM to be initialized at all. Nonetheless, it is good practice to always initalize COM before using this function."
