;                                      + 4 = Centred single button.  Note: multiple buttons are always centred
;                                      ($SS_LEFT, $SS_CENTER, $SS_RIGHT can also be used)
;                   $iBkCol     -> The colour for the message box background.  Default = system colour

Reading and learning from your code now. As you may have seen I was having a proper go at it myself, and (earlier than expected) came to some result myself.

In any case I still very much appreciate your time since I can compare and learn from how somebody with more experience goes about it.

And Yes, it´s working superbly.

Just my humble 2 cents to the UDF in general: For the sake of habits, the syntax function could be more similar to the native MsgBox function, so that when used without customisations,

ExtMsgBox($MB_SYSTEMMODAL, "Title", "This message box will timeout after 10 seconds or select the OK button.", 10)

would look and work the same as

MsgBox($MB_SYSTEMMODAL, "Title", "This message box will timeout after 10 seconds or select the OK button.", 10) ; (taken from the Helpfile as an example)

and then basically everything in a script that uses "MsgBox" could be (very simply with Search&Replace) replaced with "ExtMsgBox", initially without any real effect - until then usage of more detailed parameters is applied...

guestscripter,

the syntax function could be more similar to the native MsgBox function

The only syntax difference is the requirement to insert the required button text - and if you want the standard text, you might as well use the standard function.

And I will not be adding this "MouseTrap" option to the release UDF - it requires a Windows message handler to work and that means that coders have to be aware of this and possibly make adjustments to their own message handlers to allow the UDF to function correctly. But all is not lost - ways to get around this problem are being discussed at present so you might get a pleasant surprise some time in the future.

bdr529 · February 6, 2014

sorry but I write bad English

Syntax.........: _ExtMsgBox ($vIcon, $vButton, $sTitle, $sText, [$iTimeout, [$hWin, [$iVPos]]])

if $vIcon=128 and $iTimeout=0 EXTMSGBOX "does not work"

maybe I'm wrong?

Melba23 · February 6, 2014

bdr529,

And why should it display? By setting $vIcon to 128 you are asking it to display a countdown to 0 - and then you are setting the start value in $iTimeout to 0. The dialog does not display because it is already at the end of the countdown!

All clear?

Is there any way to have the behavior of Button 5 - "Message box with do not show again option" act as a splash screen? Basically removing the button but have the message show when an application is first opened.

#include <ExtMsgBox.au3>
#include <StringSize.au3>

; Set default button font, "Not again" checkbox, no titlebar icon
                _ExtMsgBoxSet(4 + 16 + 32, 0, Default, Default, 14, "Consolas")

                $sMsg  = "This message box was passed screen coordinates rather than a window handle "
                $sMsg &= "so it is located at 200, 200." & @CRLF & @CRLF
                $sMsg &= "It has no icon on the titlebar, a Query icon, a Taskbar button, a ""Not again"" checkbox, has TOPMOST set and uses the default font for the button and checkbox with a user-set font for the text" & @CRLF & @CRLF
                $sMsg &= "It will not time out"

$Form1 = GUICreate("GUI GUI", 1300, 543, 192, 124)

Something like this... but working

Melba23 · June 1, 2014

jbsoccerbrit,

Is there any way to have the behavior of Button 5 - "Message box with do not show again option" act as a splash screen?

Why not use SplashTextOn to create a suitable splash screen? That is why the function exists. :huh:

This UDF creates MsgBox replacements - splash screens are outside of it remit. And remember that the ExtMsgBox will show the next time you run the script - the checkbox is valid only for a single instance, not forever.

Vasim · July 2, 2014

Splendid job..

A question..:

is there any example to change the button color if that is possible?

Melba23 · July 2, 2014

Vasim,

Welcome to the AutoIt forums - and an excellent first post if I may say so!

Colouring buttons is fraught with problems because of a bug deep in the core AutoIt code (and so unlikely to be fixed) which causes all sorts of problems - coloured buttons trap the {ENTER} key, lose all their styles, etc, etc. So I strongly recommend that you do not colour buttons.

However, I have often used underlying slightly bigger labels to give buttons a coloured border if colour is really a necessity. But do not forget to disable the label control (or create it without the $SS_NOTIFY style) to prevent AutoIt getting confused and actioning neither when the overlapped area is clicked upon.

Melba23 · September 21, 2014

Synix,

That is easy enough for the user to manage - there are already enough parameters in this UDF.

Docfxit · September 26, 2014

Is there some way to have the MSG go away when a window pops up?

I have a program that doesn't open until it gets a file off a network drive. The lag time for this program to open varies greatly.

I would like the message to stay open until the program opens.

#include <GUIConstantsEx.au3>
#include <Constants.au3>
#include <StaticConstants.au3>
#include "ExtMsgBox.au3"

    GUICtrlSetFont(-1, 10)

            _ExtMsgBoxSet(1 + 32 + 64, 1, 0x0DF4E8, 0, 28, "Nyala")
            $sMsg = "I am bringing up your document."
            $iRetValue = _ExtMsgBox (64, " ", "Please Wait", $sMsg, 5, 400, 400)
            _ExtMsgBoxSet(Default)      ; Reset to default

Thank you for a really great messaging script,

Docfxit

PS: I don't need the timer at all.

Melba23 · September 26, 2014

Docfxit,

This UDF does not cater for that scenario - but a SplashText screen is just what you need.

M23

Docfxit · September 26, 2014

Thank you for the reply...

It isn't quite as nice as your UDF but I did get it to work.

Thanks,

Really cool !

Question: Is there a way to have scroll bars if there is too much text to fit vertically?

Melba23 · February 5, 2015

nassausky,

No. If you have that much text you really need a dedicated GUI.

Look at my Scrollbars UDF to see how easy it is to create one.

Thanks I saw that earlier and will revisit it now and will post a question in that topic now

Melba23 · March 30, 2015

[NEW VERSION] 30 Mar 15

Added: A new parameter to the _ExtMsgBox function to allow the dialog to display on secondary displays. The UDF default behaviour prevents simple coordinate errors from making the dialog invisible (the coordinates are adjusted to make sure it appears on the main screen as close as possible to the desired location) which does not allow the dialog to be deliberately positioned off the main display - setting this new parameter allows the dialog to be located at any position. Obviously the user who sets this parameter is now responsible for ensuring that the dialog is visible.

Thanks to cyberalau3 who asked for the change. :thumbsup:

New UDF and examples in the first post.
