alternatives to Pixelsearch?

[yeads]

is there a alternative to pixelsearch? something that is precise.

[kaisies]

Depends. What is this for?

As kaisies points out, it is a bit difficult to give you alternatives if we don't know what you're trying to do. In short answer, yes there is almost always something better and more precise than pixelsearch. What that something is will depend on your intended goal.

like if i want to make the cursor click on 'b' in a "abc" string. They all have the same color so how can i tell them apart?xy Position wont work either.

Check for more than one pixel, compare the results to an array of character pixel data.  I have never done this with variable-width fonts but if one were so inclined it might be possible to do by figuring out the first letter then stepping that letter's width.  Then solve the next letter and step again the last letter's width.

how about reading the string in the control?

REMOVED - See Malkey's awesome example below.

My code was incomplete nonsense. Malkey's example is superior.

This example will select an individual character out of a text field when that character is clicked on.

This example will not select characters from an image, where  OCR is needed.

#include <Misc.au3>
#include <Clipboard.au3>

;Opt("MouseCoordMode", 1) ;1=absolute(default), 0=relative, 2=client

Local $aMPos, $sMsg
MsgBox(0, "Instructions", '"Left mouse click" on a character,' & @LF & '  or,' & @LF & 'Press "Esc" to Exit.' & @LF & @LF & 'Press "Ok" to continue')

While 1
    Select
        Case _IsPressed("1B") ; Esc button
            ExitLoop
        Case _IsPressed("01") ; Left mouse button
            $aMPos = MouseGetPos()
            MouseMove($aMPos[0] + 5, $aMPos[1], 1)
            Do ; Prevents multiple mouse clicks - ensures one click only.
                Sleep(10)
            Until Not _IsPressed("01") ; Left mouse button is released
            ControlSend("", "", "", "^c") ; "" specifies the currently active control.  Copies the highlighted text in that control.
            If _ClipBoard_GetData() = "" Then
                $sMsg = "Cursor not over a specific character when clicked"
            Else
                $sMsg = 'Clicked on"' & StringLeft(ClipGet(), 1) & '" at absolute coordinates (' & $aMPos[0] & ", " & $aMPos[1] & ")" & @LF & @LF & _
                        'Note:' & @LF & 'Press "Esc" to Exit.'
            EndIf
            MsgBox(0, "Result", $sMsg, 3)
            _ClipBoard_SetData("") ; Could not get the script to work properly using ClipPut("") ;
    EndSelect
WEnd

When working with strings,  using the PixelSearch function would be way down on the list of possible functions to use.

See String functions in AutoIt help file.

Changed occurences of "Ecs" to "Esc".
