    ;if blue pixel found OK
    MsgBox(0,"","Found")
EndIf

This is my pic:

I want to check the color at "KLH84" position, but this pic can see through the blue background, so i dont know to define the color pixel

edit a box around the KLH84 if the search find the color white then you have got the text

[langthang084]

the position I want to check isnt alway KLH84, it can be unforeseeable. So I think should check the blue background.

[TerarinK]

Check the whole screen, as long as you choose a color that is only in the wording your fine.

[langthang084]

I use this code to check a white character on the line at KLH84 position:

if PixelSearch(90,148,90,148,0xffffff) <> @error Then 
         msgbox(0,"","CORRECT")
endif

but however KHL84 appears or not, the msgbox always show

Your logic is wrong.

$coords = PixelSearch (...)
If Not @error Then
;Correct;
Else
;Incorrect
EndIf

Christ even the helpfile has and example of what you want! READ IT!

[langthang084]

No, I thinks if @error then nothing appear. But error or not, the msgbox CORRECT always show

In this pic I check the red line and its alway show INCORRECT
