Extended Message Box - New Version: 16 Feb 24

Melba23 · October 25, 2010

I believe it is because StringSize, or the EMB is creating ControlIDs that are causing the media player's control IDs to get changed, so I'm updating the wrong controls after calling this function.

Sorry, but that is complete garbage.

AutoIt ControlIDs are internally organised by AutoIt so unless we are using exactly the same variable names in Global scope there is no way any UDF can change the ControlIDs within a script calling it.

The only Global constants and variable names in the release version of ExtMsgBox are:

; #GLOBAL CONSTANTS# =================================================================================================
Global Const $MB_IConstop   = 16 ; Stop-sign icon
Global Const $MB_ICONQUERY  = 32 ; Question-mark icon
Global Const $MB_ICONEXCLAM = 48 ; Exclamation-point icon
Global Const $MB_ICONINFO   = 64 ; Icon consisting of an 'i' in a circle

; #GLOBAL VARIABLES# =================================================================================================
Global $iDef_EMB_Font_Size = _GetDefaultEMBFont(0)
Global $sDef_EMB_Font_Name = _GetDefaultEMBFont(1)
Global $iEMB_Style = 0
Global $iEMB_Just = 0
Global $iEMB_BkCol = Default
Global $iEMB_Col   = Default
Global $sEMB_Font_Name = $sDef_EMB_Font_Name
Global $iEMB_Font_Size = $iDef_EMB_Font_Size

There are none at all in StringSize. All other variables are Local in scope.

So unless your media player controls store their ControlIDs in variables with exactly those names, there cannot be any interference. I use EMB all the time in my own media player (which includes timers, progress bars and volume controls) and have absolutely no problems at all.

I am happy to try and help you solve the problem you are having with your script, but it is certainly not what you are currently suggesting.

I found out why it was doing this after I looked at the variables I was using to call the EMB function, and found that it wasn't the UDF that was messing it up, it was me using variable names in the calling routine that was doing it.

What I had done was to copy the _ExtMsgBox function routine from your UDF (_ExtMsgBox($iIcon, $iButton, $sTitle, $sText, $iTimeout = 0, $hWin = "", $iVPos = 0)) then used that as the method to call the function in my script because I wanted to make sure that I called it with the correct parameters in the correct places, totally forgetting that some of the variable names you used in your function were the same as some of the variable names I was using in my script. So of course it was screwing up my script because I wasn't paying attention as I should have when using it.

I feel pretty dumb at the moment, but I view it as a learning experience and hopefully won't make this same mistake in the future.

I apologize for any misinformation that I posted about this excellent function because as I have said before, I really find it to be invaluable to have in my toolbox.

BrewManNH,

No problem. Thanks for owning up and clearing my UDF.

AWESOME UDF.

I'm trying the example right now and I can't figure out why the first msgBox (the one with 1 to 4 buttons) doesn't disable the parent GUI. I didn't change any code in the example script.

I'm using AutoIt version 3.3.6.1.

Melba23 · November 12, 2010

leomoon,

why the first msgBox (the one with 1 to 4 buttons) doesn't disable the parent GUI

I thought it did!

You can certainly action the buttons on the parent "EMB Test" GUI but are you saying that they actually work while the "Test 1" EMB is displayed? If so I would like to know as they certainly do not work when I run the example. :graduated:

Oo. Maybe I don't know how it's spouse to work. I though when you run the first msbBox it should disable the parent so you can not click the parent anymore. No? If it just disables the buttons on the parent GUI then it works perfect. :graduated: It's ok now. I got it working with a few more lines.

Also with the centering msgBox to the main GUI or to the desktop, it does not work on multi monitors. When you move the parent GUI to the second monitor (right monitor), the msgBox will appear at the edge of the first monitor... So I modified your code a bit to make it work for multi monitor:

#include-once

;Getting true desktop with and height
$aTSR = _GetTotalScreenResolution()

;Original code by Larry.
;Edited by BrettF
Func _GetTotalScreenResolution()
    Local $aRet[2]
    Global Const $SM_VIRTUALWIDTH = 78
    Global Const $SM_VIRTUALHEIGHT = 79
    $VirtualDesktopWidth = DllCall("user32.dll", "int", "GetSystemMetrics", "int", $SM_VIRTUALWIDTH)
    $aRet[0] = $VirtualDesktopWidth[0]
    $VirtualDesktopHeight = DllCall("user32.dll", "int", "GetSystemMetrics", "int", $SM_VIRTUALHEIGHT)
    $aRet[1] = $VirtualDesktopHeight[0]
    Return $aRet
EndFunc

leomoon,

Glad you got it working as you wanted - I presume you added a couple of GUISetState lines. :graduated:

And thanks for the multiple monitor code. I will not add it into the main release because I do not have multiple monitors and so cannot test or maintain it. But I will point to your code from the first post so others know how it can be done.

Edit: Typnig!

Awesome! :graduated:

Yea it should work with single, and dual and I think even triple+. I tested with single and dual monitors. It works exactly the way you want it. If the parent GUI is outside of monitor(s) the msgbox will appear on the edge of the monitor...

amin84 · December 2, 2010

Hello,

I have one more question. Is there any option to make the msgBox not "always on top"? I checked the example and read the udf information. I couldn't find anything. I tried to add an option to enable or disable "always on top" but the udf is a little bit advanced for me. :graduated:

Melba23 · December 2, 2010

leomoon,

I thought the whole idea was to have the EMB "topmost" so that the user would action it!

However, "the customer is king", so if you change this line:

; Create GUI with $WS_POPUPWINDOW, $WS_CAPTION style and $WS_EX_TOPMOST extended style
    Local $hMsgGUI = GUICreate($sTitle, $iMsg_Width, $iMsg_Height, $iHpos, $iVPos, BitOR(0x80880000, 0x00C00000), 0x00000008, $iParent_Win)

to read:

Local $hMsgGUI = GUICreate($sTitle, $iMsg_Width, $iMsg_Height, $iHpos, $iVPos, BitOR(0x80880000, 0x00C00000), -1, $iParent_Win)

you remove the $WS_EX_TOPMOST style. :graduated:

Melba23, never really played with this before, but I must admit, its a very nice UDF.

I do have to agree that removing the topmost bit as a default style would be better though, or optional, since a typical messagebox won't be set as always-on-top. Its easy enough to change the code as you point out, but with any new version the scripter would have to constantly revise that line..

Great job otherwise though!

amin84 · December 2, 2010

The reason for removing top most is that if the main GUI and EMB exist at the same time, if you move another window over them, EMB goes on top and main GUI goes behind the other window.

Furthermore if you remove the EMB taskbar button and disable the main gui when the EMB is activated, when you click on the taskbar button it will bring the main gui with the EMB on top anyways... Which is EXACTLY what I want.

Again GREATE UDF. I already voted 5/5, I wish I could vote multiple. :graduated:

Melba23 · December 2, 2010

Ascend4nt & leomoon,

Thanks for the compliments. :graduated:

I see what you mean about the TOPMOST style - I wonder how best to offer a choice to the user? I am loath to add yet another parameter to the already crowded _ExtMsgBox function - I am tempted to use the $iStyle parameter in the _ExtMsgBoxSet function to do something along these lines:

; Parameters ....: $iStyle      -> 0 = Normal - Button appears on TaskBar (Default), 1 = Button does not appear on TaskBar
;                               -> Adding 2 to the parameter will create an EMB without the TOPMOST style
;                   >>>>>>>>>>     Setting this parameter to 'Default' will reset ALL parameters to default values <<<<<<<<<<

Any thoughts?

BrewManNH · December 2, 2010

What I've done with the EMB calling routine, is just add things to it on my own and just set a default value if not used. I added some things to it, changed some things in it and just added parameters to the end as I went along.

Here's how I've modified it to work better for my style:

Func _ExtMsgBox($iIcon, $iButton, $sTitle, $sText, $iTimeout = 0, $hWin = "", $iVPos = 0, $Random = 0, $MaxWidth = 370, $MinWidth = 150)

I don't think you should need to add or change things when you have the full source code available and anyone can change it to suit their needs, as I have done. The change that was mentioned, changing the top most flag, can be done with an additional parameter to the calling routine and adding a variable to be set to either set or unset the topmost flag, but asking to have you do it for them is just pushing it I think. But, that's just me, I don't like asking others to do something for me if I'm not willing to do it for myself.

Melba23, that sounds like a sensible solution.

And @BrewMan:

I and others here gladly take any suggestions into consideration when creating and furthering development of UDFs. Heck, I've created a lot of additions to different UDF's per other's requests & suggestions, and additionally provided many solutions to help people out.

And hey, its not like anyone's forcing someone to change something. Melba23 can do whatever he likes with our suggestions :graduated:

amin84 · December 3, 2010

@Melba23. That sounds good.

Melba23 · December 3, 2010

Hi,

[NEW VERSION] 3 Dec 10 - Added the abilty to turn off the TOPMOST style if required.

The _ExtMsgBoxSet function header gives details of how to do this:

; Parameters ....: $iStyle      -> 0 (Default) - Button on TaskBar and TOPMOST style set.  Combine following to change:
;                                  1 = Button does not appear on TaskBar
;                                  2 = TOPMOST Style not set

and the example script shows all combinations.

If you do not want to change the TOPMOST setting you need change nothing in your current scripts. :graduated:

New UDF, example script and zip in the first post.

Tnx for the new version. It's AWESOME!

Hi m8 :shifty: ,

was playing around with this UDF to see if I could utilize it in SMF ... and noticed that your default msgbox font and size looks different to me then if I would call a standard msgbox().

You extract the data from the $tNONCLIENTMETRICS structure, this results in "Tahoma"/(11) for me.

Looking at a standard msgbox() results in "MS Shell Dlg"/(10) for me.

I changed the function _GetDefaultEMBFont() just a little and now the standard font looks exactly the same in your msgboxex() example and a standard msgbox(). Maybe you could x-check this? Had to add WinApi.au3 and left a lot of old comments in the code, definitely would need a clean up :nuke: .

Edit: Wrapped into a single call :lol: ...

Edit2: Does the font object obtained with "Local $hFont = _SendMessage($hCtrl, 0x0031) ; $WM_GETFONT" call need to be deleted with _WinAPI_DeleteObject($hFont)? Added this for now... also I noticed now, if I start the example and immediately press "Exit", the first time the confirmation box is not white. Press "No" and retry and suddenly the color is right... check, check, also happens in your original post, so I didn't mess up ...

Edit3: *sigh*... if _GetDefaultEMBFont() produces an error, the standard font size on my system is 10... but it of course needs to be 8 as an integer (Int((Abs(10) + 1) * .75))...

Melba23 · January 19, 2011

KaFu,

Hmmm - on my Vista machine I get the same font (Segoe UI, 9) in both Windows' MsgBox and my UDF version. Using your version I get a different smaller font (MS Shell Dlg, 8) in the EMB which does not match the normal MsgBox.

By the way, I always thought that MS Shell Dlg and MS Shell Dlg2 were shorthand for the real font names stored under HKLM\Software\Microsoft\Windows NT\Currentversion\FontSubstitutes - I have MS Sans Serif and Tahoma as the values in my registry. As neither of them appear in my Windows MsgBox, although it does look as if I have MS Sans Serif as the default GUI font so your function returning it is perhaps not surprising. Are you sure that MsgBoxes use the default GUI font? It does not appear so on my machine and I know I spent considerable time searching for the default MsgBox font location when I first wrote the UDF.

If I remember correctly, you run Win7. Have you set any particular styles which might have changed the default fonts? Do the values in the FontSubstitutes registry entry reflect the fonts you see in your GUIs and MsgBoxes? Does my original _GetDefaultEMBFont function return data from the $tNONCLIENTMETRICS structure or from the @error default for you - perhaps Win7 no longer stores the values there?

start the example and immediately press "Exit", the first time the confirmation box is not white. Press "No" and retry and suddenly the color is right

Definitely does not happen for me with either the original or your version. The EMB comes up in the default "whitish" colour all the time.

Please do not think I am not being defensive here, I would like to get the bottom of it but it is a bit difficult if I cannot reproduce the problems you are having.
