Control Windows Audio-Settings?
Dec 19, 2009
I have got some code and after some slight modiications now works fully for what i need - but only on XP.
However, my problem is when the software is run on Vista. My software doesn't seem to be able to control any of the Mixer Lines it's supposed to, but will randomly change the Mute/Volume level setting on the 'Application Audio' setting in the Mixer. Can anybody point me in the right direction to change settings on a Vista machine? My Module is attached below. To use in a form you must use the line: modMixer.OpenMixer() prior to any further commands. For example:
1. modMixer.OpenMixer()
2. modMixer.MuteLineInVolume = True

I have my forms all set up, I want a button on my main form that says Volume. When clicked it either opens a window above the current form with a volume control. Or opens another form that has the volume control in the center. When the slider is moved up to 100% windows is at 100% volume, when moved down windows volume moves down also.

I'm writing a program which plays audio using a windows media player control. It's quite basic but I'm running into a problem.
Soundplayer.Ctlcontrols.play()
Sleep(3000)
For some reason when this appears in my code, the sound doesn't start playing until AFTER the sleep. I have music running in the background, using another windows media player control, that continues playing just fine.
Basically, I want nothing else to happen for the duration of the sound, hence the sleep, so how can I make it so my sound starts playing BEFORE the sleep?

I am planning to create a proprietary Windows application that will let the user capture video and audio from any other Windows application and stream it onto another computer via Internet. Capturing video is easy, I could simply let the user browse all open windows (or applications) and have the user click the prefered one. But what about audio? Is it possible in Windows to capture the audio from any application?

my program is designed to run on windows7. the mixer in the taskbar lets you control volumes per application. is their a way to determin if a specific application is playing a sound? if not, how would i go about checking to see if the system is currently outputting anysound.
my app is currently setup to use a speech to text and text to speech. basicly i want it to be able to wait for the text to speach software to stop talking before my app plays internal sounds (using the My.Computer.Audio.Play)
i don't have any code to provide as i have no idea where to start.

I am working on a .NET Windows Service where I am trying to store settings that will be used when the service is started and while it is running. I have searched through posts on SO and found that using the Settings in the properties of the project is great for use with console and winforms applications. However, Google and SO are silent when it pertains to storing these settings with a windows service.

So I'm a bit new to the whole Vista/7 audio setup. My understanding is that a new "mixer" is created for each application. Is there some new .Net function which interfaces with these mixers? I'm actually trying to create an application which can adjust the MAIN system volume level as well as the mute function.
I was looking at the Endpointvolume API however I cant get it to work for me :(. Does anyone have a vb.net demo of how to harness this API?

I am creating a windows service that will do things behind the scenes without any GUI needed, thus the need for a Windows Service. The problem is though I would like to notify the user when certain events happen by playing a short audio clip. I know Windows Service's create a virtual Desktop, in which, Audio messages are not sent to the users Desktop.

I am attempting to play a set of audio files continuously using a tree view. I am having troubles looping through an array to play one song after another in the selected parent node. It seems to work if I only use one song in the array but it doesn't want to actually loop through and keep playing; it goes through the loop but once the first song is over it stops. I am unsure if looping through an array in the AfterSelect sub routine is the best way of doing this,
Here is the entire Sub routine for the AfterSelect on the tree view.trvMain is the name of the entire tree view.wmpMain is the Windows Media Player COM.trvJazzHancock is the parent node for the two audio files I'm attempting to loop.

I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.

I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.

Im trying to capture the audio played on my laptop. so i have searched the internet and found a source code for doing exactly that. the problem i have is that my audio device is not listed in the dropdown box (see picture) but it does when its run on windows xp (im running windows 7 x64) the goal of this application would be to capture my friends radio stream and save the individual played mp3's to a loction on my hard drive.(yes i have permission) i have included the source code so perhaps some 1 could have a look at it.

I have a database application developed around Access with VBA,I have used the Speech SDK and developed an application that in conjunction with MSCOMM 6.0 library calls into a remote IVR system.It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one problem;I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.
I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well). This means that I must route the system audio output to the SR engine audio input. It seems that I must use an InProc SR instance - however in VBA that type is not recognized - since the shared SR uses the microphone as input by default. there is some statement to the effect that it is difficult in Microsoft's Help file. I'm unable to set the SR audio input to the modem output stream in VBA.As needed I can accomplish the C++ interface using an ActiveX object or a DLL to expose the missing API to VBA?

I have a form that runs completely full screen. The form has MDI child windows. My issue is for some reason whenever i try to use a setting in a child window the program freezes up and i have to end it with the task manager. For instance if i add a string to a string collection when the child form opens like i would normally do if it wasn't a child form the form will open then the program will freeze. Am i doing something wrong or is there any way to get this to work?

I have a VB.NET solution built in Visual Studio 2010. It consists of a class project, a service, and a setup project. I have successfully created a setup, and run the setup from the "Release" directory of the setup project (outside of Visual Studio). It installed the service (on the same machine as where the project is), and the service seems to be running fine. The service executable is installed in a directory under c:program files (x86) along with some DLL's it is dependent of. The service (actually the class project I mentioned above) uses some settings from My.Settings. As far as I know these settings are stored in a app.config file in the project directory, as well as in a settings.settings file in the My Project directory under the project directory.
Neither of these files are installed by the installer. But the service can only run if it can read the settings. So where does my service get these settings from? To check if it still reads the settings from the VS project directory, I have temporarily renamed that directory, but that didn't affect the correct operation of the service.

Is it possible as it is showing me that it is only a readonly.I know that we can simply change it by using me.text="" But I have a problem in my application as I have the below code where On every time the form loads it is erasing the text.

MyBase.OnLayout(e)

If you edit a service in Windows 7 and go to the Log On Tab, there is an option to "Allow service to interact with desktop". I'm trying to ensure that it is set for a certain service using VB.NET.
Note: Doing this during the install of a program is not an option. It has to be done at run time.

I've written a windows service in VB.NET 2.0 and the service needs to know a few file paths and other settings when it starts in order to be able to do what its supposed to do. These are settings that users of my service need to be able to configure themselves so I cant hard code them in.At the moment I just have the service look for a file named Config.INI in the same directory that it is being run from and if this file exists it attempts to read the settings in from there... this works perfectly, but it just feels a bit clunky and old. If it was a normal windows app I would store the settings in an XML file in the user's application data folder or something but as this is a Service then thats not possible as it is not run by any one user (well technically it is, the Local System account). I then thought about using the registry but I seem to recall people saying that you should avoid storing settings in the registry if you can really, especially with the new security in Vista and Server 2008.
