I have a vb .net application where the user can choose a directory into which an excel file is written. If the user selects a system directory (yes, my users do this, don't ask me why) then a System.Runtime.InteropServices.COMException is thrown at runtime. I am handling this exception telling the user to please select another directory.

Does anyone know how to get and set the system sound volume? I have tried every method I've found on the net and none of them work. I've tried the winmm.dll APIs with no luck. I've also tried waveOutGetVolume/waveOutSetVolume, which didn't work. I'm using Win 7, but need a solution that works on XP+.
Right now I use the VolumeUp keyboard event, but I need to be able to get the volume and set it to a specific level.
I have an application that plays wav and mp3 files using the Microsoft.DirectX.AudioVideoPlayback.Audio()function. It works fine, and I can easily set the volume level of the playback... within limits.
That limit is the system volume level. I can set the playback level for the mp3, but if the system volume is muted or set real low it may still play softly.
So how do I set the master volume level, including making sure it isn't muted?
caN SOMONE guide me how to make my own system sound control in vb.net like a slider or % or anything!!! just a volume control!

How can I control the Computers volume inside visual basic? (like you have the speaker icon and when you click on it Volume scroll thing) at the bottom left of Windows, but I want it in my program. I am running Windows 7 (if that makes any difference
View 1 RepliesI'm trying to make a utility that will fade out the system volume (for when I fall asleep listening to my music). In XP and prior, controlling the system audio was very simple, however, in Vista and 7, I can't figure out how to do it. Because in Windows 7 each application has it's own volume control, lowering the volume doesn't affect the system overall - only the current app. Can anyone point me to a resource how to do this? Every forum posting that I've found on this topic is about XP, and doesn't work under newer versions of Windows.

I have a device (a few actually) that connects via USB to a PC. From here it acts like a basic storage device using FAT32 as the file system. The other thing is that it won't accept drive names (C:, E:, G: etc) to it so instead you need to use its Volume GUID to connect. I have retrieved this painlessley through MountVol.exe but thats where the difficulties ended.I am not trying to access the file system through VB.NET/C#.net (either will be fine - fluent in both ;) ). In Windows Explorer I can easily visit '\?Volume{71E4C2C7-E511-4B2A-BF5C-569B2B25784E}apic' to access the device and its files. I can also use CMD and the Dir command to go through the files. Just .NET cant seem to cope. I understand the GUID changes on each PC and I am OK with this as I can use MountVol to get the GUID and run the console app with command arguments as it will always be a human initiating the command.
I have tried manually entering the path via Console.ReadKeys but this also fails to even see the directory above and any of the files inside one being 'dev' without an extention. I can use System.IO operations without extensions on "normal" drives (ie those
with letters) so I know it's not the extension causing problems. I did a Try/Catch with a StreamReader pointing to the file to see what was spurted out:
System.ArgumentException: Illegal characters in path.
at System.Security.Permissions.FileIOPermission.HasIllegalCharacters(String[]
str)

how to get current volume of system sound device in windows 7 ?I looked up in google but every solution returned values like -1, 4686346, ...
View 1 RepliesI am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).
I have the following code.
Imports System
Imports System.IO
Public Class frmUpdater
When I try to run this I get the following error: The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.I am trying to read all drives with FAT16, FAT32 and NTFS.My PC is using NTFS and is running normally.
I am working on a little project for my phone creating some sort of remote to turn up/down my system volume via wifi. The phone will send data to a text field on the website lets say such as "vol up" and the vb app sitting on the computer will be constantly reading this text field for key words like "vol up", "vol down". when it see's a recognized command it reacts by turning the volume up and so on. And one more thing: Is it possible to have a vb app that uses http? E.g., sits on port 80 itself and can be accessed via local ip.

View 1 RepliesI'm attempting to use waveOutSetVolume from coredll.dll to gradually increase the audio volume from silent (or near silent) to maximum.

Public Enum Volumes As Integer
OFF = 0
LOW = 858993459

OK, and here's some API documentation which doesn't make a lot of sense to me in this particular context. What is low-order word and high-order word and how can they both exist in a single value?
· dwVolume New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence. If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.
