No sound with display

[Guest]

The Public declare function for the mciExecute is at the top of the module as
is the other Public declare function which I use for .wav files. The sub
that turns the midi file on and off is titled PlayMidiFile. The last sub is
the one that calls the PlayMidiFile during normal code execution. I have
stepped through the code and it is finding the midi file and is telling it to
execute. The problem is that there is no sound. I have to assume that it
does not execute. There have been several automatic downloads to my system
lately and I have no idea what they might have affected, but this code was
working perfectly until I tried it today. I can play the midi file using the
Windows Media Player, so the midi file is not corrupt.

Does anybody have a clue? It has me snowed.



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

Public Declare Function mciExecute Lib "winmm.dll" _
(ByVal lpstrCommand As String) As Long

Sub PlayMidiFile(MidiFileName As String, Play As Boolean) 'Function for
calling midi files
If Dir(MidiFileName) = "" Then Exit Sub ' no file to play
If Play Then
mciExecute "play " & MidiFileName ' start playing
Else
mciExecute "stop " & MidiFileName ' stop playing
End If
End Sub

Sub x()
MidiStr = ""
On Error Resume Next
MidiStr = Dir("c:\windows\media\*.mid")
On Error GoTo 0
If MidiStr <> "" Then
Set fs = Application.FileSearch
With fs
.LookIn = "C:\Windows\Media"
.Filename = "*.mid"
If .Execute > 0 Then
MySnd = .FoundFiles(1)
End If
End With
PlayMidiFile (MySnd), True
End If
End Sub

Have you tried playing the file with media player or similar? (To make sure
the sound isn't set to mute or the volumn is turned down.)

That is what is so confusing. The file plays ok on the media player, so the
only thing I could surmise was that, although it indicates that it is
initiating the execute command to play, in is not in fact executing. I was
just reviewing some of the recent automatic updates and can't see anything
that would directly affect the internal code execution. Most of the updates
were related to blocking external hackers into Windows system files.

Oh, well. Maybe somebody smarter than me will have the same problem and
figure it out. It is not in a critical system, but I like to have things
work after I spend a lot of time putting them together.

Checking the return value of the API call may give you an better idea of the
error.
But I see you are not using PlaySound, which is the easiest way.

Hi Nick, if I add PlaySound to the mci function, it throws a critical error.
It was working fine without it for several months. This anomally just popped
up here in the last couple of weeks. Don't know the exact time it formed
because I don't run the program that much. I was just doing some file
maintenance and ran that program to see if it needed tweaking and sure
enough, it needed something. I can't help but believe this problem is a
result of some automatic security downloads. Stepping through the code
indicates that it should be playing.

How are you calling PlaySound.
Exanple from API-Guide:

Private Const SND_ASYNC = &H1 ' play asynchronously
Private Const SND_FILENAME = &H20000 ' name is a file name

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 Form_Load()
PlaySound "C:\WINDOWS\MEDIA\TADA.WAV", ByVal 0&, SND_FILENAME Or SND_ASYNC
End Sub
