how to stop the playsound when it is in loop

and if there is a way to call it from different forms
and play for each form different sound, please show me an example code

thank you very much.

How to START play?

Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

PlaySound TempFileName, ByVal 0&, SND_FILENAME Or SND_ASYNC Or SND_LOOP Or SND_APPLICATION

play for each form different sound

---

Place this in a module

vb Code:

Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" _
(ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Place this in the form load event of your each form....

vb Code:

Private Sub Form1_load()
    Dim lngRet As Long, strSNDFile As String
    '~~> Change this part for every Form to the respective file...
    strSNDFile = "c:\windows\media\explode.wav"
    lngRet = PlaySound("SystemStart", 0, &H0)
End Sub

thank you
what i try to guess that first i have to play this line in form_load

Code:

---

    lngRet = PlaySound("SystemStart", 0, &H0)

---

then every file i want

i tried it
-first it make the windows start sound
-second it doesn't make a sound for each form
btw i'm talking about MDI childs

-third what about my first question
how to make it shut up

i tried this

Code:

---

PlaySound "", 0, 0

---

but it doesn't work

i have to close VB for the sound to turn off
very confused :(

i want to use this instead of direct X because direct X 8 needs installation
on Vista and above

anyone ?

Sorry.. had missed this post...

Once it starts playing it will not stop till it finishes playing the file...

The best way to handle it is to use files which play only for 2-3 seconds...

Have made few changes

Place this in a module

Code:

---

Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" _
(ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Public Const SND_ASYNC As Integer = &H1

---

Place this in every form/MDI Child load event

Code:

---

Private Sub Form_Load()
    Dim lngRet As Long, strSNDFile As String
    '~~> Change this part for every Form to the respective file...
    strSNDFile = "c:\windows\media\explode.wav"
    lngRet = PlaySound("SystemStart", 0, SND_ASYNC)
End Sub

---

Now if you see that whenever you open a form, the sound which you have specified will play...

By the way, if you have noticed that in the above code I have added one line...

Quote:

---

Public Const SND_ASYNC As Integer = &H1

---

This "SND_ASYNC" plays the sound asynchronously i.e it moves to the next line of code immediately after starting to play the sound and have it play in the background....

One of these should stop the current sound

PlaySound vbNullString, 0&, SND_NODEFAULT
or,
PlaySound vbNullString, vbNull, SND_NODEFAULT
or
PlaySound vbNullString, 0&, 0&


'''''''

Code:

Option Explicit
' To hear a sound for an event, the event must have a sound file
' associated with it in the users windows sound panel otherwise it will not play.
' If a sound is not avalable SND_NODEFAULT will return nothing, otherwise a beep will be heard.

Const SND_ALIAS_SYSTEMASTERISK      As String = "SystemAsterisk"
Const SND_ALIAS_SYSTEMDEFAULT      As String = "SystemDefault"
Const SND_ALIAS_SYSTEMEXCLAMATION  As String = "SystemExclamation"
Const SND_ALIAS_SYSTEMEXIT          As String = "SystemExit"
Const SND_ALIAS_SYSTEMHAND          As String = "SystemHand"
Const SND_ALIAS_SYSTEMQUESTION      As String = "SystemQuestion"
Const SND_ALIAS_SYSTEMSTART        As String = "SystemStart"
Const SND_ALIAS_SYSTEMWELCOME      As String = "SystemWelcome"
Const SND_ALIAS_YouGotMail          As String = "MailBeep"

' playsound Params
Const SND_LOOP = &H8
Const SND_ALIAS = &H10000
Const SND_NODEFAULT = &H2 ' silence if no sound associated with event
Const SND_ASYNC = &H1 ' play async (don't freeze program while sound is playing)

Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Private Sub Command1_Click()
    ' loop "you got mail" sound until stopped!
    PlaySound SND_ALIAS_YouGotMail, vbNull, SND_ALIAS Or SND_NODEFAULT Or SND_ASYNC Or SND_LOOP
End Sub

Private Sub Command2_Click()
    PlaySound "SystemExclamation", vbNull, SND_ALIAS Or SND_NODEFAULT Or SND_ASYNC
End Sub

Private Sub Command3_Click()
    PlaySound "SystemAsterisk", vbNull, SND_ALIAS Or SND_NODEFAULT Or SND_ASYNC
End Sub

Private Sub Command4_Click()
    ' by default windows XP doesn't have a sound associated with the question event,
    ' the user neeeds to set it to a file in the sound control panel.
    PlaySound "SystemQuestion", vbNull, SND_ALIAS Or SND_NODEFAULT Or SND_ASYNC
End Sub

Private Sub Command5_Click()
    PlaySound SND_ALIAS_SYSTEMDEFAULT, vbNull, SND_ALIAS Or SND_NODEFAULT Or SND_ASYNC
End Sub

Private Sub Command6_Click()
    'Stop sound
    PlaySound vbNullString, ByVal 0&, SND_NODEFAULT
' or PlaySound vbNullString, vbNull, SND_NODEFAULT
End Sub

@ Edge

"SND_NODEFAULT" (Value : &H2)
It is used if the specified sound cannot be found, terminate the function with failure instead of playing the System Default sound. If this flag is not specified, the System Default sound will play if the specified sound cannot be located and the function will return with success.

This is the complete Flags table

Quote:

---

Flags Table
===========
SND_ALIAS = &H10000: lpszName is a string identifying the name of the system event sound to play.
SND_ALIAS_ID = &H110000: lpszName is a string identifying the name of the predefined sound identifier to play.
SND_APPLICATION = &H80: lpszName is a string identifying the application-specific event association sound to play.
SND_ASYNC = &H1: Play the sound asynchronously -- return immediately after beginning to play the sound and have it play in the background.
SND_FILENAME = &H20000: lpszName is a string identifying the filename of the .wav file to play.
SND_LOOP = &H8: Continue looping the sound until this function is called again ordering the looped playback to stop. SND_ASYNC must also be specified.
SND_MEMORY = &H4: lpszName is a numeric pointer refering to the memory address of the image of the waveform sound loaded into RAM.
SND_NODEFAULT = &H2: If the specified sound cannot be found, terminate the function with failure instead of playing the SystemDefault sound. If this flag is not specified, the SystemDefault sound will play if the specified sound cannot be located and the function will return with success.
SND_NOSTOP = &H10: If a sound is already playing, do not prematurely stop that sound from playing and instead return with failure. If this flag is not specified, the playing sound will be terminated and the sound specified by the function will play instead.
SND_NOWAIT = &H2000: If a sound is already playing, do not wait for the currently playing sound to stop and instead return with failure.
SND_PURGE = &H40: Stop playback of any waveform sound. lpszName must be an empty string.
SND_RESOURCE = &H4004: lpszName is the numeric resource identifier of the sound stored in an application. hModule must be specified as that application's module handle.
SND_SYNC = &H0: Play the sound synchronously -- do not return until the sound has finished playing.

sorry guys, it was my fault, i'm shame

instead of vbnullstring i wrote "", and it didn't work of course
until i decided to go by edge advice, and wrote vbnullstring
and suddenly everything start to work as expected
so i checked in the help
and i found this

Quote:

---

vbNullString String having value 0 Not the same as a zero-length string (""); used for calling external procedures

---

i think this can also solve me another problem with calling API

now one thing still left,
the playsound for each child doesn't work.
though if it will not, it also good, but i prefer to know if this is possible, and how

thanks for great help

Have you put it in each child form's load event mentioning the relevant file name?

i put in the form_load event
this line

Code:

---

playsound "SystemStart", 0, SND_ASYNC

---

and in other sub, where i need to play, i put this line

Code:

---

PlaySound TempFileName, 0, SND_FILENAME Or SND_ASYNC Or SND_LOOP

---

so ?

no one know the answer for that ?

maybe an example code with MDI and 2 childs to demo how to use playsound to play different wave for each child at the same time ?

Here you go :wave:

see attached sample.
Project of 5ms? modified (2)
:wave:

hay man, i'm really glad you tried to help,
and i really appreciate this.

sorry that i didn't explained myself,
i am looking after a way, to play from 2 different childs, at the same time,
so i can hear for example 2 waves playing at the same time.

the way you show, is what i know already,
is when you play a sound, any previuos sound, is turned off.

Not with PlaySound

But look here

So if you are making a game or a music app, it is better to use DirectSound or WAVEMIX32, for more control over your sound, and allow more than one sound to play at the same time. Here are some tutorials on DirectSound:

Sorry, I misunderstand, but... however your initial request was:
how to stop the playsound when it is in loop
that's quite different from what you ask now!


Then you must to use MCI.
As example, you can start by this project:
C:\Program files\Microsoft Visual Studio\MSDN98\98VS\1033\SAMPLES\VB98\MCI

Open the prject MCITest and make some changes:

1.
Open frmMCITest form, in the routine below
Private Sub AI_WAVEAUDIO_Click()

insert this statements

Code:

---

    New_Wave
    Exit Sub

---

2.
In same form, add this new routine:

Code:

---

Public Sub New_Wave()
    DialogCaption = "Audio Wave - "
    Dim fWave As frmWave
    Set fWave = New frmWave
    fWave.Caption = "Audio Wave"
    frmOpenDlg.dlgOpenFile.Filter = "File Wave (*.wav)|*.wav"
    fWave.mciWave.DeviceType = "WaveAudio"
    fWave.Show
End Sub

---

That allow you to open two or more instances of frmWave.

3.
Open frmWave form, and in the routine:
Private Sub AI_OPEN_Click()

Comment the lines that close the wave device:
' If Not mciWave.Mode = vbMCIModeNotOpen Then
' mciWave.Command = "Close"
' End If

4. Run the project
5. from main menu click 2 times to Audio_Wave menu item: this open 2 instances of frmWave (move one form to see both)
6. in both instance of frmWave open a different WAVE file
7. finally, start play both the frmWave


Take note that the above project use MCI32.OCX, however you can achieve same result via API, learning MCI functions:

Example here

:wave:

thanks for that, so for that i was looking for,
for an answer that this is can't be done with playsound.

i can't use MCI because i need to play my waves in loop,
(they're very short, only one cycle waveform, to use later in a synth),
and MCI doesn't support that (i think) that's why i needed PlaySound.

EDIT: but maybe with MCI API it's possible to play in loop ?

Yes, of course.
Search on MSDN help file for MCI control event Done, and properties Notify, NotifyMessage and NotifyValue.

When I start playing a sound using -

RetVal = PlaySound("C:\HelloWorld.wav", 0&, &H20000)

is there any way to get a handle on that operation whereby I could kill the operation ?

If one is playing multiple sounds, one could put each handle (if available) into an array where it can be retrieved to kill the particular sound. My problem is that when I close the form that is playing the sound, using Unload Me, the sound keeps playing.

Will appreciate any info on availability of a handle to identify the particular sound that would allow killing the sound.

boblite....start your own thread...this one is real, real old.

thanks for the heads up, Sam
