..I'm coding the High Contrast theme editor and using the _ChooseColor() I wandered why it does not keep the the custom colors I've added.
Found that adding a static declaration would do it. But why stop there. Why not keep going, So I put this together that is non code braking ( backwards compatible ), to replace the one in <Misc.au3>

Here a little script to load a TGA image file and create a GDI+ bitmap. Currently supported TGA formats are  1/8/15/16/24 and 32-bit.
As v0.85 is written completely in AutoIt, it might take some time to convert larger 8/15/16/24/32-bit images. ☕

Hello Forum, 
I have one special Combo-box [with BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE) ] and if I press one button I want to change the Combo-box's background color, and after I press Button B I want to change it to the basic settings and it not works.
I wanna do this with one combo-box.
I have already tried several methods and I tried  GUICtrlComboSetColors that I have found on this forum.
(But this methods works perfectly with Cobo boxes that don't have BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE). 
Here is the example code
#include <ButtonConstants.au3> #include <ComboConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #Region ### START Koda GUI section ### Form= ;$CBS_DROPDOWNLIST ;$GUI_SS_DEFAULT_COMBO $Form1 = GUICreate("Form1", 504, 249, 252, 227) $Combo1 = GUICtrlCreateCombo("", 136, 24, 193, 25,BitOR($CBS_DROPDOWNLIST, $GUI_SS_DEFAULT_COMBO, $CBS_SIMPLE)) ; I want to change this special combo's background color if I press button 1 $Button1 = GUICtrlCreateButton("Button1", 112, 96, 75, 25) $Button2 = GUICtrlCreateButton("Button2", 264, 96, 75, 25) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### GUICtrlSetData($Combo1," " & "|" & "apple" & "|" & "banana" & "|" & "cherry" ," ") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 GUICtrlSetBkColor($Combo1,0x0078D7) Case $Button2 ;Makes the original bc color GUICtrlSetBkColor($Combo1,0xFFFFFF) EndSwitch WEnd  
Thanks you in advance your help

Heres a function for searching for a bitmap within another bitmap. The heart of it is written assembly (source included) and working pretty quick I feel. I have included an example which is pretty basic and should be easily enough for anyone to get the concept. 
You will be given a small blue window that will take a screencapture of that size:

 
It will then take a full screenshot and highlight all locations that it found

Please let me know if you have any issues or questions. Thanks!
