Hey all,

I got really bored and decided to try something a little different. I made this script as an example of a neat feature you can add to your scripts in the future, a built-in magnifying glass! It's a pretty simple script, but I've never seen anyone else use au3 this way. I'm sure there are plenty of other better methods (DLL calls), but I thought this was quite cool when I got it working. So, without further adue:

; ------------------------------------------------------------------------------
;
; AutoIt Version:   3.1.1 Beta
; Author:           CodeMaster Rapture <Rapture2k4@Netscape.net>
; Language:         English
; Script Function:  A little application that magnifies a 20x20 area under the
;                   mouse. This is just an example of what CAN be done in Au3.
;
; ------------------------------------------------------------------------------

#include <GUIConstants.au3>

HotKeySet("{ESC}", "Quit")

;Magnifying a 20x20 area of the screen
Global $GUI_Pixel[400]
Global $GUI = GUICreate("Zoom x2 Au3",80,80,0,0,$WS_POPUP+$WS_BORDER,$WS_EX_TOPMOST)

$count = 0
;Let's create a bunch of labels and make them 4x4 pixels in size.
For $iterX = 0 To 79 Step 4
    For $iterY = 0 To 79 Step 4
        $GUI_Pixel[$count] = GUICtrlCreateLabel("",$iterX,$iterY,4,4)
        $count += 1
    Next
Next
GUISetState(@SW_SHOW)

Global $LastPos[2] = [0,0]

While 1
    $count = 0
    $MousePos = MouseGetPos()
    
;Got creative here, since we want to magnify a 20x20 area around the mouse,
;I just start with a negative number for each loop. It still counts 20x20, merely
;starts at a strange index. :)
    For $iterX = -10 To 9
        For $iterY = -10 To 9
            GUICtrlSetBkColor($GUI_Pixel[$count],PixelGetColor($MousePos[0]+$iterX,$MousePos[1]+$iterY))
            $count += 1;Loop thru our Pixel Array (20 * 20 == 400 elements)
        Next
    Next
    
;I placed this in to remove some choppiness. One less API call == good.
;This also allows for animation over an area of the screen.
    If ($LastPos[0] <> $MousePos[0] Or $LastPos[1] <> $MousePos[1]) Then
        WinMove("Zoom x2 Au3","",$MousePos[0]+15,$MousePos[1])
        $LastPos[0] = $MousePos[0]
        $LastPos[1] = $MousePos[1]
    EndIf
    
;Sleeping 1-10 ms takes 70-60% (respectively) CPU usage on my machine
    Sleep(10)
WEnd

Func Quit()
    Exit
EndFunc

Tell me whatcha think :),

Love it!! Now you just need the Cross hairs :)

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Customized a bit by using a DllCall that I found earlier today on the forum.

#include <GUIConstants.au3>

$MagWidth = InputBox ("Magnify Area", "What should the WIDTH of the magnified area be?")
$MagHeight = InputBox ("Magnify Area", "What should the HEIGHT of the magnified area be?")
$MagZoom = InputBox ("Magnify Area", "What should the ZOOM of the magnified area be?", 2)

Global $SRCCOPY = 0x00CC0020
Global $dll[3], $DeskHDC, $GUIHDC

$dll[1] = DllOpen ( "user32.dll")
$dll[2] = DllOpen ( "gdi32.dll")

Global $GUI = GUICreate ("Zoom x2 Au3", $MagWidth * $MagZoom, $MagHeight * $MagZoom, _ 
    MouseGetPos (0), MouseGetPos (1), $WS_POPUP+$WS_BORDER, $WS_EX_TOPMOST)

GUISetState(@SW_SHOW)

Global $LastPos[2] = [0,0]

While 1
    MAG()
    $MousePos = MouseGetPos()
    If ($LastPos[0] <> $MousePos[0] Or $LastPos[1] <> $MousePos[1]) Then
        WinMove("Zoom x2 Au3", "", $MousePos[0] + $MagWidth/2 + 5, $MousePos[1])
        $LastPos[0] = $MousePos[0]
        $LastPos[1] = $MousePos[1]
    EndIf
    
    Sleep(10)
WEnd

Func MAG()
    $DeskHDC = DLLCall("user32.dll","int","GetDC","hwnd",0)
    $GUIHDC = DLLCall("user32.dll","int","GetDC","hwnd",$GUI)
    If Not @error Then
        DLLCall("gdi32.dll", "int", "StretchBlt", "int", $GUIHDC[0], "int", _
            0, "int", 0, "int", $MagWidth * $MagZoom, "int", $MagHeight * $MagZoom, "int", $DeskHDC[0], "int", _
            MouseGetPos (0) - $MagWidth/2, "int", MouseGetPos (1) - $MagHeight/2, "int", $MagWidth ,"int", $MagHeight, _
            "long", $SRCCOPY)
        DLLCall("user32.dll","int","ReleaseDC","int",$DeskHDC[0],"hwnd",0)
        DLLCall("user32.dll","int","ReleaseDC","int",$GUIHDC[0],"hwnd",$GUI)
    EndIf
EndFunc

Func OnAutoItExit()
    DllClose ( $dll[1] )
    DllClose ( $dll[2] )
EndFunc

You're not being descriptive enough - that's what you're doing wrong.

My question is simple: How do I run or compile the above scripts ?

Do I have to include them in existing project or they are stand-alone ?

Running the first script I get error on line 23:

$count += 1

Error: Expected a "=" operator is assignment statement.

If run compiled (Beta) I get same error in line 0.

Running the second script I get three times InputBox, but after entering the third box I get error on line 13 saying " Incorrect number of paramerers in function call", then a second error on line 13 sayin "Error in expression"

If I compile the second script I get: "Unable to open the script file".

Thank you for helping

Well it works fine when I use it. Are you using Scite? If so, make sure you run scripts with Alt+F5 and compile with Alt+F7. Also, make sure that you answer each of the input prompts, because I didn't declare the vars beforehand (as I should have, but it was late).

I couldn't get it to work. I actually designed this to see if I could make a zoom application for fullscreen satallite imaging software (DirectX 9). The only thing I can get to work is a flickering tooltip :/. I'm working on a DLL in VC++ that will solve this problem tho. It will also have a bunch of other neat things like Onscreen Display text boxes, shapes, scrolling banners, etc (think xFire for Au3). I'm just torn between using OpenGL or DirectX for this.
