Hi Guys!

I have a code that use everytime I need to hide the task bar:

FUNCTION HideTaskBar(TaskBarHidden)
TaskBarStatus=TaskBarHidden
#DEFINE SW_NORMAL 1
#DEFINE SW_HIDE 0
DECLARE LONG SHOWWINDOW IN WIN32API LONG , LONG
DECLARE LONG FindWindow IN WIN32API STRING, STRING
HWND=FindWindow("Shell_TrayWnd","")
IF HWND=0
	RETURN
ELSE
	lngState=IIF(TaskBarStatus, SW_HIDE, SW_NORMAL)
	=SHOWWINDOW(HWND,lngState)
ENDIF
ENDFUNC

This code works fine always, but now I get the following error:

Cannot find entry point SHOWWINDOW in the DLL

This error appears on this line:

DECLARE LONG SHOWWINDOW IN WIN32API LONG , LONG

Any help would be appreciated. Thanks in advance!
