Hello,

I'd like to ask u guys a question. When I once draw a line(with _WinAPI_DrawLine ), how to redraw it? I mean to remove the present one and make second one in the other place?

From the helpfile

_WinAPI_RedrawWindow

Its what I used once anyway

[zwierzak]

I don't really get how to do it. Any example code pls?

[JohnOne]

There is examples'o'plenty in the helpfile, even under the heading of the very function you want to use.

I couldnt do it any better than that.

I came to a conclusion, that using GDI library would be better idea, because i want to draw pictures in application, not on the screen. What then should i do with the GDI drawed line? I mean how to delete it

I have this example:

#include <GuiConstantsEx.au3>
#include <GDIPlus.au3>

Opt('MustDeclareVars', 1)

_Main()

Func _Main()
    Local $hGUI, $hGraphic, $hPen

    ; Create GUI
    $hGUI = GUICreate("GDI+", 400, 300)
    GUISetState()

    ; Draw line
    _GDIPlus_Startup ()
    $hGraphic = _GDIPlus_GraphicsCreateFromHWND ($hGUI)
    $hPen = _GDIPlus_PenCreate ()
    _GDIPlus_GraphicsDrawLine ($hGraphic, 10, 150, 390, 150, $hPen)

    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE

    ; Clean up resources
    _GDIPlus_PenDispose ($hPen)
    _GDIPlus_GraphicsDispose ($hGraphic)
    _GDIPlus_Shutdown ()

EndFunc   ;==>_Main

Ok it works. But how to delete this line after hmm 5 seconds? sleep(5000)...and? I really don't get this and i cannot find any appropiate function in my HelpFile. Neither do this, which u mensioned. Sorry if I'm too troublesome for u ;/
