Questions on tbc source code

Hi,

As I read the script code, there is a small point that is not clear to me.

Could someone help me on this?

At the beginning of the script, we have :
Global $Title = "BlueStacks App Player"
Global $HWnD = WinGetHandle(WinGetTitle($Title))

And later in the _CaptureRegion function:
Local $hDC_Capture = _WinAPI_GetWindowDC(ControlGetHandle("BlueStacks App Player", "", "[CLASS:BlueStacksApp; INSTANCE:1]"))

Is there any reason to use different instructions ?
Do you expect
ControlGetHandle("BlueStacks App Player", "", "[CLASS:BlueStacksApp; INSTANCE:1]")
and
WinGetHandle(WinGetTitle($Title))
to retrieve different handles ?

Thanks 😉

due to some unable to use background mode. 2 different instruction were used. both still get BS windows.

OK, thank you for your answer.
