i would like the F2 key to switch tabs in a program. also if the last tab is active, it should revert to the 1st tab or move in reverse. how is this possible? i provide the code below..

Code:
#IfWinActive ahk_class #32770
F2::
SendMessage, 0x1304,,, SysTabControl321, ahk_class #32770  ; get total tabs
TabCount = %ErrorLevel%
ControlGet, WhichTab, Tab, , SysTabControl321   ; get current tab

If WhichTab = TabCount            ; if current tab equals total tab
  Control, TabLeft, , SysTabControl321      ; move left
Else
  Control, TabRight, , SysTabControl321      ; move right

;TrayTip, %appname%, TabCount = %TabCount%`nWhichTab = %WhichTab%
#IfWinActive

I tried with the SendMessage example from the help file:
Code:

#IfWinActive,AutoHotkey Help
F2::
SendMessage, 0x1304,,, SysTabControl321, A  ; get total tabs
TabCount = %ErrorLevel%
ControlGet, WhichTab, Tab, , SysTabControl321, A   ; get current tab

If WhichTab = %TabCount%            ; if current tab equals total tab
  SendMessage, 0x1330, 0,, SysTabControl321, A
Else
  SendMessage, 0x1330, %WhichTab%,, SysTabControl321, A
TrayTip, %appname%, TabCount = %TabCount%`nWhichTab = %WhichTab%
return
#IfWinActive

I tested with the help file for AHK, changes in red.

The ", A" part is actually not necessary since #IfWinActive sets the Last Found Window.

To know why
Code:
If WhichTab = %TabCount%
works where
Code:
If WhichTab = TabCount
does not, read FAQ: When exactly are variable names enclosed in percent signs?.
