No sound

[Utpal]

Hi everybody,
I have Foxpro 2.6a for Windows on Windows 2000 Professional. Executing the command "?? CHR(7)" does not produce any sound. Is there a solution to this ?

Try setting the following to get a more "Windows" like tone:

SET BELL TO "C:\WINDOWS\CHIME.WAV" && or any wave you like.

Then issue:

?? CHR(7)

You might also try:

? CHR(7)

Thanks Scott. I know this works, but only if a sound card and multi-media speakers are present. Mine has them, but most computers in India don't, especially in offices. I want the sound to come from the PC speaker which is present in most computers. I have developed a standard Inventory package for which I want that. It used to work fine on Windows 3.11 and Windows 98. The problem occurs in Windows 2000.

Utpal,
I see your point... in place of your ? CHR(7), try this routine instead:

=ALERTONE(3)


(Then, in your &quot;Common&quot; procedure file (whatever file you issue a &quot;SET PROCEDURE TO <filename>&quot; command, add this Procedure:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*
* This procedure is used to establish the alert tone used
* by functions which use an audable alert when needed.
*
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

PROCEDURE ALERTONE

PARAMETER M.ALERTCOUNT
*
PRIVATE M.ALERTCOUNT
*
IF PARAMETERS() < 1
M.ALERTCOUNT = 1
ENDIF
*
FOR M.SOUNDCOUNT = 1 TO M.ALERTCOUNT
SET BELL TO 1650-(18*M.SOUNDCOUNT), 3
?? CHR(7)
SET BELL TO 650-(5*M.SOUNDCOUNT),3
?? CHR(7)
ENDFOR (M.SOUNDCOUNT)
*
SET BELL TO
*
RELEASE M.ALERTCOUNT
RELEASE M.SOUNDCOUNT


This sends 3 tones to the PC speaker. Due to &quot;Speed&quot; and &quot;Timing&quot; issues, single tones are sometimes missed by faster processor's or some OS's.

Thanks Scott, but your code did not work. Still there is no sound.

 

[Scott24x7]

Hmmmm... very odd. This may sound stupid, but have you verified the PC speaker is attached and functioning in the machine?

It's not clear whether you are checking this out on a machine without a sound card. Many times the presents of one will &quot;disconnect&quot; the PC speaker. Also, not all OEM's supply a Windows Speaker Driver, and I don't believe MS officially supports one anymore. Since NT / 2000 / XP don't allow direct access to the hardware, you may not be able to use any &quot;DOS&quot; like solutions.

Rick,
I'm actually running a FP2.6 app on WinXP Pro, and my calls to the &quot;ALTERONE&quot; procedure I have above still work...

I also have a SoundBlaster LIVE! and a Delta66 ProAudio board in the same machine, with the PC speaker.

That said, I would agree very much with your statement that some audio cards do, however, override your pc speaker.

As far as I am aware (though, I could be wrong), the PC Speaker doesn't require a seperate &quot;Driver&quot; to function in Windows, as it is a call to a specific address, not a call to an IRQ.

Best Regards,
Scott

Utpal,
Some computers do not come with a PC speaker
anymore.I think It's absurb but I have 7
Gateway Profile III's that do not have them,
or the software to drive them. therefore will
not respond at all to any chr(7) command.

Hope this helps

Thanks to all ! I do have a PC speaker. I am sure about that because in FoxPro for DOS 2.6, it produces sound with the same ?? Chr(7) command. Maybe I'll have to look for a PC speaker driver for Windows 2000.

I haven't checked out that on a machine without a sound card. I only tried it out on my computer which has a sound card.
