Scrolling thru a window with tabs

[Shibuya 0]

I'm trying to write a small function, one that scrolls thru a SysTabControl32 until the desired tab is active.

The script below is my attempt on it.

Tested it on IE7 with the Printing Preferences window of MS Document Image Writer, somehow the script exited the while loop without reaching the correct tab.

$title = "Printing Preferences"
$tab = "About"

Opt("WinTitleMatchMode", 3)
$print_handle = WinGetHandle($title)

MsgBox(0, "", $print_handle)

While WinExists($print_handle)
    ;MsgBox(0, "Details", "test1")
    If WinActive($print_handle, $tab) Then ExitLoop     ;exit loop when the required tab is active
    ;MsgBox(0, "Details", "test2")
    If WinWaitActive($print_handle) Then Send("^{TAB}") ;scrolls thru each tab
    ;MsgBox(0, "Details", "test3")
    Sleep(1500)     
WEnd

MsgBox(0, "Details", "test4")

Any idea what's wrong with the script?

$title = "Printing Preferences"
$tab = "About"

Opt("WinTitleMatchMode", 2)
$print_handle = WinGetHandle($title)

MsgBox(0, "", $print_handle)

While WinExists($print_handle)
    WinActivate($print_handle)
    If ControlCommand($title,"","SysTabControl321","CurrentTab", "") = 3 Then ExitLoop
    ControlCommand($title,"","SysTabControl321","TabRight", "")
    Sleep(1500)  
WEnd

MsgBox(0, "Details", "test4")

hmmm....is there no way I to reference the tab using the text on the tab, other than using the reference number returned by ControlCommand($title,"","SysTabControl321","CurrentTab", "")?
