Muting announcements in VLC Player

[Villa82]

Greetings,

I am trying to achieve the following (see description in code window below). If I remove the Do/Until loop, then the Window Title detection works fine and I get through to the message box. When I do use the Do/Until loop, as shown below, the code skips to the messagebox even though the VLC Player Window does not have the "Announcement" string in the title. Why does this occur?

#cs ----------------------------------------------------------------------------

 AutoIt Version: 3.3.8.1
 Author:         D

 Script Function:
    Mutes VLC Radio Announcements.
    
    1. Wait for a Window with a Title containing "Announcement" string.
    2. Upon window/string detection, activate the VLC Player Window and mute the sound via the VLC menus.
    3. Wait until there is no Window present with title containing the "Announcement" string.
        4. Activate the VLC Player Window and unmute the sound via the VLC menus.
    5. Loop to the beginning.

#ce ----------------------------------------------------------------------------

; Script Start
AutoItSetOption("WinTitleMatchMode",2)  ; Partial title match

While 1
   WinWait("Announcement", "")
   WinActivate("Announcement", "")
   Send("!a" & "{DOWN 6}" & "{ENTER}")  ; Press VLC mute via VLC menus
   MsgBox(0, "Test", "Mute Me!")
   Local $Mute=1    ; Mute enabled
   
   Do
      If Not WinExists("Announcement", "") Then
         $Mute=2    ; Mute disabled
      Else
         ContinueLoop
      EndIf
   Until $Mute=2
          
WEnd

Exit

Thanks in advance!

You're telling the If statement to process the $mute = 2 if the window DOESN'T exist, so $mute will equal 2 as long as that window isn't there.

Hi,

How does the script make it through to the If statement? Shouldn't it wait on the following line?

  WinWait("Announcement", "")

WinWait function = Pauses execution of the script until the requested window exists.

 

Thanks

Now you're mixing up what you asked in the first post. Are you having issues with the Do loop, as initially stated, or are you having issues with the WinWait? Do you by any chance have a window open that has the word Announcement in it anywhere? Such as calling your script Announcement.au3, and editing it in Scite?

Hi,

Sorry for the confusion You're spot on for my script having the string "Announcement" in it and thus undesirably triggering the WinWait. Thanks for your help!

Below is the final script that works.

; Script Start
AutoItSetOption("WinTitleMatchMode",2)  ; Partial title match

While 1
   WinWait("Announcement", "")
   WinActivate("Announcement", "")
   Send("!a" & "{DOWN 6}" & "{ENTER}")  ; Press VLC mute via VLC menus
   Local $Mute=1    ; Mute enabled
   
   Do
      If Not WinExists("Announcement", "") Then
         Send("!a" & "{DOWN 6}" & "{ENTER}")    ; Press VLC mute via VLC menus
         $Mute=2    ; Mute disabled
      Else
         ContinueLoop   ; Continue Do Loop Until Announcement string disappears from window title
      EndIf
   Until $Mute=2
          
WEnd

I'm glad you got it working. Wait until you have a script called the same as a program you're trying to run with a Run command and you have thousands of instances of it running the same program over and over until your computer crashes. Been there, done that, have the T-shirt.
