I have searched the web for code relating to changing the system volume, muting the system volume, and outputing the current level of the volume as an integer, using VB.NET.
All the code that I have found either doesn't work, or is very long.
how do i control the volume level that the speakers output?

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?

View 1 RepliesI am trying to make an application that is able to turn master volume on and off (Mute unmute). And what I have done so far is increasing and decreasing volume, but if sound is turned on mute then it wont start anyway. And that was really a lot of code to do that, so is there an easy way to mute sound or is it equally alot to do.
I have tried
SendKeys.Send(Keys.VolumeMute)
But with no effect, and I have tried using
chr(173)
instead of keys.volumemute. (I have a variable that looks if the sound was mute or not from start so it can be default afterwards).
How can I make it so a command button or whatever you'd like to use can mute the computers volume, then unmute it?

View 4 RepliesThis morning I was trying to work out how to update a User Control from a button on a page using jQuery.Refresh User Control with jQuery.From the info gleaned from this article: http [url]...I now have a method of loading a User Control as a page with jQuery using the converted .VB example from the codeproject.com article.However... this won't render into the browser, Firebug is giving the error "element must be contained within a form runat=server tag" So I posted this question:
re: better way to manage a dynamic select list using jQuery and User Control.Since posting that though,I have thought about it further, and believe it is the fact that the jQuery Handler class created by the codeproject code is send the browser a complete page.Given that I sadly don't really understand what that codeproject code actually does I am having trouble working out how to alter it.What I need it to do is not return a Page at all, but I guess, an HTML string, which can then be pasted directly as HTML into the div as required.how to alter that code to return an HTML string?
It seems like this would be a very easy thing to accomplish, but, from what I can tell, it's most definitely not. My OS is Windows 7. All I need to do is get the current volume/audio level - the master volume. When you click the little speaker icon in the task bar and change the volume - I need that number. All I need to do is get the current volume and assign it to a label. So if the volume is at 74 when the application starts, I need my label to display 74. I've been searching for days now for a way to do this and I'm starting to get frustrated. I've looked everywhere. I've tried 3 different classes, at least a dozen different codes, assorted imported dll's- none of it even came close to what I need. From what I can tell, the current methods are all designed for windows xp. I need a way to do it in windows 7.

View 4 RepliesIt is times like these that I miss the old VB6 language I wish I could hide the current forn and show another form which - this is the important thing - to be on the same level that the previous form was . You see , I used to use this code :
Me.Hide Form2.Show However , sometimes in VB .NET this does not work the way I want it to . You see , the current form does get hidden and Form2 is shown indeed ; however , Form2 is shown somewhere in the background . If there are other programs opened at that time , then Form2 is shown behind all those programs , that's what I mean by saying I want it to be shown in the same level as the previous form was the only way out , I found , was to reverse the code :
Form2.Show Me.Hide In this way Form2 is successfully shown right where the previous form was shown (above the other programs) but in some cases this also is not pleasant because it might take some time for Form2 to load while at the same time the previous form is still visible on the screen and therefore for a slight time both forms are shown one over the other , which is surely not nice . That's why I still want to first hide the first form and later show Form2 .

View 8 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
