Don't show me your useless message again !

[perfaram 1]

Hi !

Here's a short code that creates a MsgBox with a "don't show this message anymore" checkbox.

Also provided, a function to clear this setting.

Moreover, at the end of the script you'll find a GUID generator : you will have to use a different one for each of yours msgboxes, otherwise the "don't show..." will apply everywhere (and none of your boxes will show !)

In the following code, uncomment the eighth line (;_RestoreDefaultSettings()) to clear the settings.

$hGui=GUICreate("GUI principale", 300, 300)
GUISetState()

Local $sIdentifier = "{315Ef1E9-1078-4E74-8AB4-171BE0D793E71}"
Local $iDefault = 1

;_RestoreDefaultSettings()
$msgNr=_MessageBoxCheck(33, 'TITRE', 'Bonjour,'&@CRLF&'Qui es-tu, toi qui joue avec le registre ?', $sIdentifier, $iDefault, $hGui)
ConsoleWrite('MsgBox returned : '&$msgNr)

Nice! As a less-invasive rewrite of the above (will not any leave permanent registry entries), where the script itself is subsequently responsible for showing or hiding the msgbox (storing the response in an INI file or whatever) consider:

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIDlg.au3>

Local $msgNr = _WinAPI_ShellMessageBoxCheck($MB_OK + $MB_ICONINFORMATION, "SHMessageBoxCheckW Test", "Ne pas perdre sa vie à la gagner")
MsgBox(0, "", "Msgbox = " & $msgNr & @LF & "CheckState = " & ((@extended = $GUI_CHECKED) ? "$GUI_CHECKED" : "$GUI_UNCHECKED"))

Func _WinAPI_ShellMessageBoxCheck($iFlag, $sTitle, $sText, $iTimeout = 0, $hWnd = Null)
    Local Const $ShowMeNot = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\DontShowMeThisDialogAgain"
    Local Const $sID = "_WinAPI_ShellMessageBoxCheck"

    Local $bCheckbox = $GUI_UNCHECKED
    Local $msgN_Call = _WinAPI_MessageBoxCheck($iFlag, $sTitle, $sText, $sID, 0, $hWnd)

    If @error Or $msgN_Call = -1 Then
        $iRet = MsgBox($iFlag, $sTitle, $sText, $iTimeout, $hWnd)
        Return SetError(1, $bCheckbox, $iRet)
    EndIf

    If RegDelete($ShowMeNot, $sID) Then $bCheckbox = $GUI_CHECKED

    Return SetExtended($bCheckbox, $msgN_Call)
EndFunc

 

It just returns @Extended as $GUI_CHECKED or $GUI_UNCHECKED for quick reference.  Like I said, this could just be stored in an INI/Array so there's no need for persistent registry spam, GUID's, or anything like that (making it easier for a user to "reset" individual message-states in the future).

That being said, if someone did prefer the original method where the system itself suppresses the msgbox call, I suggest using _WinAPI_CreateGUID to generate a true GUID, as randomising can never be considered "unique". Just a thought.

This function is already in the AutoIt UDFs I thought?

[Kilmatead 10]

It is, but in the same way as you'll never learn anything about Mont Saint-Michel from Google Street View (except how not to do it), no one ever learned anything from a generically codified dllcall/@error trap, which is all the WinAPIDlg header gives you.  We're here to play, after all.

@Kilmatead : THIS is totally true !

Moreover, my function has a fallback in case the MessageBoxCheckW interface is not available 

[guinness 1,450]

Alright, just saying.

It is for you but not for others, so I don't see the point to post an existing function.

 

Edit : And FYI, this is the right way to generate a GUID :

#include <WinAPICom.au3>
 
ConsoleWrite(_WinAPI_CreateGUID() & @Lf)

But I guess you wanted to do it yourself too

Br, FireFox.

@FireFox : Well... no, I didn't know...

BTW, the GUID generator I used isn't mine, it comes from here : '?do=embed' frameborder='0' data-embedContent>>

No problem
