Marquee UDF - New release 13 Jan 2019

[Melba23]

Efo74,

I am but a hobbyist coder as well - but with perhaps just a little more experience than you . It was ~50 years ago I got my first experience of programming a computer to play Nim thanks to my very progressive 6th form maths master. We were using the mainframe of Imperial College - where a few years later I took my only formal programming classes (in Fortran) as part of my Aeronautical Engineering degree. Since then I have used various flavours of Sinclair home computers and then PCs, using Basic, assembly and AutoIt languages. It has given me a lot of pleasure over the years.

I am making a "timesheet" in autoit ... we hope that the project is not bigger than me. Thanks again for all your advice and valuable help.

Guys, my first day in looking into this great script. I need to modify the text displayed in the Marquee. I assume it is being called by $iIndex or $sText.

how do I modify what is currently running. I am new and under pressure to change the domain logon script to run marquee.au3 with the updated corona message. Help @Melba23 and all you other coders out here 😭

[Melba23]

karldrogo,

Welcome to the AutoIt forum.

The text displayed by the marquee is set by the $sText  parameter of the _GUICtrlMarquee_Create function as explained in the function header:

;    $sText - The text (or HTML markup) the marquee should display

So you need to modify the string setting that parameter to get a new message.

If you need more help than post the code that you are using - see here how to do it

Greetings @Melba 23 can you use your UDF with a transparent background, with only the letters overlaying an image?

[Melba23]

Belini,

I do not believe you can have "transparent" as the background colour of a marquee, sorry.

[Belini]

Ok and thanks for responding

... a possible way to make transparent background,
but perhaps only useful if you want to create a large standalone marquee on your desktop (not to overlay it on an image within a gui ...

#include <WindowsConstants.au3>
#include "Marquee.au3"

#include <WinAPI.au3>

$hGUI = GUICreate("Big Ticker", @DesktopWidth, 50, 0, 0, $WS_POPUPWINDOW, BitOR($WS_EX_LAYERED, $WS_EX_TOPMOST))

; ----- make $AlphaKey transparent -----------------------------------
Global $AlphaKey = 0xFFFFFF
_WinAPI_SetLayeredWindowAttributes($hGUI, $AlphaKey, 0, $LWA_COLORKEY)
GUISetBkColor($AlphaKey, $hGUI)
GUISetState(@SW_SHOW, $hGUI)
; --------------------------------------------------------------------
Global $sText = "The quick brown fox jumps over the lazy dog."

$iMarqueeIndex = _GUICtrlMarquee_Init()
_GUICtrlMarquee_SetScroll($iMarqueeIndex, 0, Default, "left", Default, 50)
_GUICtrlMarquee_SetDisplay($iMarqueeIndex, 0, 0xFFFF00, $AlphaKey, 26, "Comic Sans MS")
_GUICtrlMarquee_Create($iMarqueeIndex, $sText, 0, 0, @DesktopWidth, 50)

MsgBox(0,'', 'hit ok to end the script')

Thanks @Chimp but what I really needed was to overlay an image.

I wanted to maintain the effect it has on the image and too without transparency whenever i change the background image i will need to change the background color of the text message too.

@Belini maybe something like this ?

expandcollapse popup

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <WinAPISysWin.au3>
#include <WindowsConstants.au3>
#include "Marquee.au3"

$sFileName = @ScriptDir & "\Jukebel.jpg" ; your pic in post just above
If Not FileExists($sFileName) Then Exit MsgBox(0, "Exit", "Image not found")

_GDIPlus_Startup()
$hImage = _GDIPlus_BitmapCreateFromFile($sFileName)
$hBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
$iW = _GDIPlus_ImageGetWidth($hImage)
$iH = _GDIPlus_ImageGetHeight($hImage)

$hGUI = GUICreate("", $iW, $iH, -1, -1, $WS_POPUP, BitOr($WS_EX_LAYERED, $WS_EX_CONTROLPARENT))
_WinAPI_UpdateLayeredWindowEx($hGUI, -1, -1, $hBitmap)

$hGUI2 = GUICreate("", $iW, $iH, -1, -1, $WS_POPUP, BitOr($WS_EX_LAYERED, $WS_EX_MDICHILD), $hGUI)
GUISetBkColor(0xABCDEF, $hGUI2) ; transparent
_WinAPI_SetLayeredWindowAttributes($hGUI2, 0xABCDEF)

$sText = "The quick brown fox jumps over the lazy dog."
$iMarqueeIndex = _GUICtrlMarquee_Init()
_GUICtrlMarquee_SetScroll($iMarqueeIndex, 0, Default, "left", Default, 50)
_GUICtrlMarquee_SetDisplay($iMarqueeIndex, 0, 0xFFFF00, 0xABCDEF, 26, "Comic Sans MS") ; 0xFFFF00 = yellow
_GUICtrlMarquee_Create($iMarqueeIndex, $sText, 5, 10, $iW, 50)

GUISetState(@SW_SHOW, $hGUI2)
GUISetState(@SW_SHOW, $hGUI)

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

GUIDelete($hGUI2)
GUIDelete($hGUI)
_WinAPI_DeleteObject($hBitmap)
_GDIPlus_BitmapDispose($hImage)
_GDIPlus_Shutdown()

Edit : Removed $WS_EX_TOPMOST extended style from $hGUI . Added $WS_EX_CONTROLPARENT extended style (making image draggable : AutoIt feature) . ESC to Exit

New version - 13 Jan 2019

 - Added: 2 new functions to hide/show and existing marquee.

New UDF and example script in zip format: Marquee.zip

As always, ready for compliments and/or complaints!

M23

How do I pause and restart the scrolling? I am trying to implement a tele promptor using this UDF.

[Melba23]

BlackEvil,

You can start and stop the scrolling by using _GUICtrlMarquee_SetScroll to set a very low scroll speed followed by _GUICtrlMarquee_Reset to apply it - but this also resets the text to the start which I imagine is not what you want for a teleprompter.

However I have seen example marquees that just pause - I will see what I can find.

at this link (https://github.com/aamirafridi/jQuery.Marquee) there is a javascript (which in turn also relies on jquery) which allows different scrolling directions; up, down, right and left. It also allows the "pause" and "resume" methods.
A while ago I sketched out a little script that allows that javascript to be used by embedding a "browser control" into an AutoIt GUI, (more or less like this UDF does too)
If you want to try it you can download the BrowserControl.zip file that you find at this link (https://www.autoitscript.com/forum/topic/200338-browsercontrol-companion/) and the script to try is called Example_Marquee.au3 (you have to unzip the whole folder)
That example doesn't use the "pause" and "resume" methods, but you can easily try them out like this: 

$hMarquee.marquee('pause') ; To pause the marquee at any time.
$hMarquee.marquee('resume') ;  To resume the marquee after being paused previously.

 

[Melba23]

Gianni,

Thanks - I will look into that.

Is there a way to pause & resume the marquee? I am working on a teleprompter application where I will need to pause the scrolling when user click on a button and then resume again on user action.

I just realized by seeing my own question previously that my hobby project is lying untouched for quite some time and I have to make this functionality my own...  😋😒
