I'm looking to build a VBA form application that will allow me to use the WMP Ax control and specifically target a waveOut device for the audio output. The goal being that the application could have multiple WMP Ax controls each one targeting a different waveOut like a mixer.
Does anyone know if this is possible? I haven't found anything in the WMP API. If this needs to be done in C# I will change the code just need to know if it's possible.
I have read that NAudio might be the way however I'm working with a proprietary Windows audio codec from 2009 that is based on WAV. Only WMP has been able to open it.

Windows Volume Mixer shows audio output for individual applications.
Using NAudio, what is the right way for me to tap into this information? I essentially want to be able to make my application say:
Always record all audio input/output. Unless otherwise specified, only keep a buffer of the last 30 seconds. Throw the test away. (I know how to do this)
When Skype, Vonage, or Ring Central plays audio for more than 5 seconds, ask the user if they want to start saving the audio. (How would I do this?)
If so, save the 30-second buffer to a file and then start recording live. (I know how to do this)
Thanks for the help!
Windows won't let you capture audio from individual applications. You can use NAudio's WasapiLoopbackCapture to capture audio from all applications.
If you just want to see audio output levels for all apps, that can be achieved with the IMMDevice APIs which NAudio has wrappers for. It doesn't come with a specific demo showing that, but there's another open source project, EarTrumpet that you could explore to see how its done.
I'm building a Kinect application in Unity (C#) that tracks multiple people. My stumbling block is how to test this without having several live 'actors' in front of the sensor.
I know Kinect Studio allows you to record live streams, but don't think this can be played back so that it feeds a Unity app. I am using the Kinect for Windows Unity package as a starting point.

Any Kinect or Unity experts care to chime in?
Actually you can use recorded data to playback them without any "actors".
While you are running your app (and without the need of an actual Kinect device plugged in your PC), open Kinect Studio and chose Open (Read-Only) from File. Click then on the Connect icon under the Play tab:
After that, using the Play icon (the typical triangular-shaped one), your recordings will be send to the KinectService, so you can test your app without any actors.
I have purchased a simple biometric fingerprint reader that is usually used for laptop security through a USB connection. It is just called biomentric finger print reader, not branded! It came with the software for creating security for laptop, and it works great.
However, I had a different idea for it: I am intending to create a database of users fingerprints so that I can identify which user swiped their fingers on it, ie, to use it for different users' authentication using fingerprints. I don't seem to be making any head or tail on how to go about that.
I would like to find out if there is other kind of software to install that will make this gadget print the fingerprint or a code to say a spreadsheet or database whenever I swipe a finger on it? I was thinking it would be a simple as when I use a bar code scanner to print codes of various items to a spreadsheet.
Could someone please advise how to go about this. I believe it should do that but I just dont know where to start.
thanks.
As an alternative wrapper to WinBioNET as mentioned by Robinicks there is WinBiometric.Net.
Disclaimer: I do not own this project.
It has a really nice test project for playing around with the different API functions available in the Windows Wiometric Framework. This test project was monumental in helping me understand the Windows Biometric Framework.
The WinBiometric.Net wrapper has a claim of 100% API coverage, a NuGet package and has the MIT license.
I found it to generally have a very high quality of code as well.
As for storing the fingerprints in a database you could use the WinBioCaptureSample API function to capture a sample, which can then be stored in a database.
The sample can be converted into an image as well, there is a nice example of this in the wrapper.
I know this is an old question but I figured I'd post anyway.
You can use the WBF (Windows biometric Framework) API that is free, but you must first verify if your biometric device is WBF compatible. The documentation and samples for WBF are for C++, but there is a wrapper sample in C# that you can download here: Cirrostrata biometrics Regarding how to convert the scanned data into an image, you can check this post: How to convert winbio data into image. Hope this helps to start.
You can use the WinBioNET .NET wrapper for Windows Biometric Framework (WBF). It has a demo winforms app in the solution. Just open it up, select the demo app as the "startup project" and run. If you have any devices connected it will enumerate it at startup.
Hi I've used the shockwave flash com object to embed my flash file. I have buttons you can click on within the flash movie. Is it possible to get flash to notify my winform app which button has been pressed. It's developed using actionscript3. I'm using the latest vb.Net.
You can either use FSCommand, or use ExternalInterface. The later is better, although it may be harder to understand at first because of the format it uses, although if you've already solved the CallFunction (or SendFunction?) method argument, it's the same.
There are documentation and a sample C# project in Adobe's site, but I don't know the exact URL.
EDIT: To catch FSCommand and ExternalInterface calls there are two events you can subscribe to.
Also, you could also use sockets (either binary or XML).
That's a very open question as there would be many ways to do this depending on how your website and winforms applications are setup.
My initial suggestion would be to have your flash movie call some client side javascript on the button clicks. The javascript could post to a .Net SOAP webservice for instance which logs the button interaction to an associated database. Then your winforms application could finally check the database for the presence of new button click records.
This is just one high level suggestion based on the very high level question asked. If there's more specific information available then this can be refined.

Haven't found this in my search on Stackoverflow - I know I've seen a tool like it before, for obtaining control names or IDs in Windows apps which can then be used for reference in automated testing, in tools like AutoIt. Can anyone suggest one?
I've tried the OLE/COM Object Viewer and while it has control lists, there's no interactive method with it. Like the web developer toolkit in Firefox where you can click a control and get all the information about it, I'm after a similar app for Windows testing.
It's called Spy++.
Found the tool I wanted, either NUnitForms - which means you can use the NUnit Framework to access windows forms, and includes a Recorder tool for identifying the controls, as well as Managed Spy for giving the individual component names as well as every bit of other info - font, color, size. Very nice.
