Unable To Select A Value From A Dropdown Of Windows Form Using Autoit?

Using the following code

ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "This is my default value (TEST) - First")

or
ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "select", "This is my default value (TEST) - First")

It selects the combo box but not selecting the desired "this is my default value (TEST) - First" from the list. Basically what it is doing is selecting any value that starts with t . e.g first value is "TMP". So instead of exactly matching it is selecting any first character match.how to force it to select the exact string from list.Also tried using the following code but nothing seems to work

WinWaitActive($title)
$Index = _GUICtrlComboBoxEx_FindStringExact($hcombo, $sText)
_GUICtrlComboBoxEx_SetCurSel($hcombo, $Index)[code].....
