Hi

i need draw line in a rectangle , without leaving line out the rectangle

+ i need Line connects with the Mouse pointer without repeatint

this my code but there is problem :

#include <GDIplus.au3>

$hGUI = GUICreate("" , 400 ,400)
GUISetState()

_GDIPlus_Startup()
$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
_GDIPlus_GraphicsDrawRect($hGraphic , 1 + 400/7 , 1 + 400/7 , 300 , 300 , _gdiplus_pencreate())

Do
$hPos = GUIGetCursorInfo($hGUI)
ToolTip("X : " & $hPos[0] & " Y : " & $hPos[1] , 5 , 5)
if $hPos[0] > 358 Then
 $hPos[0] = 358
Elseif $hPos[0] < 58 Then
$hPos[0] = 58
Elseif $hPos[1] > 358 Then
$hPos[1] = 358
ElseIf $hPos[1] < 58 Then
$hPos[1] = 58
EndIf
_GDIPlus_GraphicsDrawline($hGraphic , 200 ,200 , $hPos[0] , $hPos[1],_gdiplus_pencreate())
until GuiGetmsg() = -3

_GDIPlus_GraphicsDispose($hGraphic)

Try this:

#include <GDIplus.au3>

AutoItSetOption("MouseCoordMode", 0)

Global Const $iW = 400, $iH = 400, $iBgColor = 0xF0F0F0
Global Const $hGUI = GUICreate("", $iW, $iH)
GUISetBkColor($iBgColor, $hGUI)
GUISetState()

_GDIPlus_Startup()
$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
$hPen = _GDIPlus_PenCreate()
$hBitmap = _GDIPlus_BitmapCreateFromScan0($iW, $iH)
$hCtxt = _GDIPlus_ImageGetGraphicsContext($hBitmap)
_GDIPlus_GraphicsSetSmoothingMode($hCtxt, 4)

Global Const $iPosX = 50, $iPosY = 50, $iWidth = 300, $iHeight = 300

Global $iMPosX, $iMPosY
Do
    _GDIPlus_GraphicsClear($hCtxt, 0xFF000000 + $iBgColor)
    _GDIPlus_GraphicsDrawRect($hCtxt, $iPosX, $iPosY, $iWidth, $iHeight, $hPen)
    $hPos = GUIGetCursorInfo($hGUI)
    $iMPosX = $hPos[0] < $iPosX ? $iPosX : $hPos[0] > $iPosX + $iWidth ? $iPosX + $iWidth : $hPos[0]
    $iMPosY = $hPos[1] < $iPosY ? $iPosY : $hPos[1] > $iPosY + $iHeight ? $iPosY + $iHeight : $hPos[1]
    _GDIPlus_GraphicsDrawLine($hCtxt, $iW / 2, $iH / 2, $iMPosX, $iMPosY, $hPen)
    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, $iW, $iH)
Until GUIGetMsg() = -3

_GDIPlus_GraphicsDispose($hGraphic)
_GDIPlus_GraphicsDispose($hCtxt)
_GDIPlus_BitmapDispose($hBitmap)
_GDIPlus_PenDispose($hPen)

thank you UEZ

excuse me , plz fix this code :

Don't use

_GDIPlus_GraphicsDrawEllipse($hCtxt , $iW / 2 , $iH / 2 , 1 ,1 , _GDIPlus_PenCreate(0x99FF0000 , 2))

in a loop. This will cause a memory leak because a pen object will be created permantely!
