Can't get "GetSelected" to work

[Mr. Analogy]

I"m trying to get and set the text of a combo box. Can't get it to work, although I can mainpulate other controls (textbox, etc.) on the same form.

I've tried to manipulate the Combo Box on 3 differeent programs:

Goldmine

A vb script:

Opt("WinTextMatchMode", 2)   ;1=complete, 2=quick
Opt("WinTitleMatchMode", 1) ;1=start, 2=subStr, 3=exact, 4=advanced

$ComboBox="Tedit1"
$ComboBoxIDNum=461162
$Checkbox="TCheckBox1"
$TextBox="ThunderRT6TextBox1"
$WindowName="Form1"

;msgbox (0,"combo box text",ControlCommand ($WindowName,"",$ComboBox,"GetSelected", "")); does not work
msgbox (0,"debug","GetCurrentSelection=" & ControlCommand ($WindowName,"",$ComboBox,"GetCurrentSelection", "")) 
ControlHide ($WindowName,"",$ComboBox) ;fails
ControlCommand ($WindowName,"",$Checkbox,"Check","")  ;works


is this behavior:
1. As intended, and the apps I've tried to interact with just have odd combo and listboxes?  (My examle here is with a Combo Box, but have had same symptom with ListBox)
2. An error in my script.
3. A bug in AutoIT.

Any help appreciated.

This code requires beta, and also works on windows standard combo box, not sure if it work on any other programs custom combo boxes.

but feel free to give it a try, might work for you.

Global Const $CB_ERR = -1
Global Const $CB_GETCURSEL = 0x147
Global Const $CB_GETLBTEXT = 0x148
Global Const $CB_GETLBTEXTLEN = 0x149

$hcombobox = ControlGetHandle($WindowName,"",$ComboBox)
$ret = DllCall("user32.dll","int","SendMessage","hwnd",$hcombobox, "int", $CB_GETCURSEL, "int", 0, "int", 0)
MsgBox(0,"test",$ret[0])
$s_text = ""
_ComboGetLBText($hcombobox, $ret[0], $s_text)
MsgBox(0,"text",$s_text)

Func _ComboGetLBText($hcombobox, $i_index, ByRef $s_text)
    Local $ret = DllCall("user32.dll","int","SendMessage","hwnd",$hcombobox, "int", $CB_GETLBTEXTLEN, "int", $i_index, "int", 0)
   Local $i, $len
    $len = $ret[0]
   $s_text = ""
   Local $p
   $p = DllStructCreate ("char[" & $len + 1 & "]")
   $ret = DllCall("user32.dll","int","SendMessage","hwnd", $hcombobox, "int", $CB_GETLBTEXT, "int", $i_index, "ptr", DllStructGetPtr ($p))
   If ($ret[0] == $CB_ERR) Then
      DllStructDelete ($p)
      Return $CB_ERR
   EndIf
   $s_text = DllStructGetData ($p, 1)
   DllStructDelete ($p)
   Return $ret[0]
EndFunc  ;==>_ComboGetLBText
