SelectString (or FindString and SetCurrentSelection) in ControlCommand to select a string in ComboBox out of GUI

[Yijie]

I fail to use SelectString (or FindString and SetCurrentSelection) in ControlCommand to select a string in a ComboBox. 

Below are several versions of my codes: 

ControlCommand ("Merge Channels", "", 1, "SelectString", $sD12ID)

Local $sOccrefD1 = ControlCommand ("Merge Channels", "", "ComboBox1", "FindString", $sD12ID);find occurrence ref for D1/D2
ControlCommand ("Merge Channels", "", "ComboBox1", "SetCurrentSelection", $sOccrefD1) ;select the found occurrence ref

$index = ControlCommand("Merge Channels", "", 1, "FindString", $sD12ID)
ControlSend("Merge Channels", "", 1, "Select", $index)

So I have tried changing among the possible options I know. I have also tried changing the ControlID. I have a for loop outside of this and it selects the first option in the ComboBox in the first iteration and ignores the selecting bit afterwards. 

I saw some solutions including using _GUICtrlComboBox_SelectString but to use this you need to create your own ComboBox. I need to select one from an already existing one in another software so I don't think it helps. 

I also tried the example in this page. It only ran the Win+r without selecting the file (I have changed the file name to one that I have on my computer. https://www.autoitscript.com/forum/topic/129841-selecting-a-exact-string-from-dropdown/

Could anyone help me please?

Here's the really weird part about this, i compiled a combobox example from the help file, and then tried to interact with it, but only the first line works, the dropdown works, but nothing else, the second line just gives an error, tried the findstring too, same thing.

ControlCommand("ComboBoxEx Get Combo Control", "", 10000, "ShowDropDown")
Sleep(1000)
$res = ControlCommand("ComboBoxEx Get Combo Control", "", 10000, "SelectString", '093 : Random string')
ConsoleWrite($res&' - '& @error&@CRLF)

Maybe there's a bug? I dont see any reason why it shouldn't work.
