VS 2010 Using 3 Or More Sound Outputs Or Multiple Sound Devices

Jul 21, 2011

I'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.

Direction For Sound Through Sound Card?

May 27, 2011

Is there a way to generate a pure tone (e.g. 440 Hz) for a specified period of time through the sound card without using having to find or make a separate .wav file for each tone.I tried using the "Beep" function, but while it produces the tone for a specified period, it sounds broken up into a (probably 500ms) time frame which repeats with an audible space between the repetitions.

Asp.net - IHttpHandler For Images Producing A Stackoverflow In IE?

Jun 24, 2009

I have a directory of images that reside outside the context of my web application that I need to serve to the user. Currently I'm using an IHttpHandler to serve the images and using some javascript to navigate through a set of images (the navigation is primitive for now). I followed examples for using IHttpHandler to serve images closely but when I view the images in firefox the browser hangs and when I view in IE I get a "Stack overflow at line: 0".

Code for the IHttpHandler

Public Class ShowImage : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) _

Producing Array Of Unique Values

Mar 17, 2012

I need to create an array, then iterate through a string, adding the string value to the array only is it does not already exist, to produce an array of unique values. The issue I am having is with the array.length operation - on a array that is nothing I am unable to retrieve the array length (0), as such I am unable to redimensionalise the array to be array length (must be array length as arrays are indexed from 0), providing me the ability to add the new value to the array and then continue the loop until all values have been checked to see if they exist within the array (using contains) and the value contain only unique values..

Linq To DataTable Not Producing Distinct Values?

Oct 19, 2010

I have a datatable which has been dynamically generated from FoxPro tables using a UNION Select statement. e.g.SELECT * FROM x UNION SELECT * FROM y UNION SELECT * FROM Z ORDER By v_alue1This produces a datatable with about 100 rows, each containing many fields, one of which is c_olor. From this datatable, I would like to select the distinct colors and then output in a dropdown.I have a public class Color which just has one property which I can then use as the DataTextField and DataValueField for the dropdownlist

Public Class Color
Private _c_olor As String
Public Property c_olor() As String

Text Formatting Isn't Producing Expected Results

Oct 4, 2011

I'm trying to make a simple tool to format SQL code so that I can use it in VB.When I put in the following:

USE master
CREATE DATABASE netGuest
GO

I get...

"USE master" & vbCrLf & _"
CREATE DATABASE netGuest" & vbCrLf & _"
GO" & vbCrLf & _"

So it almost works. Really the only thing not working is that the lines are ending with the " rather than starting with them.Here's my code:

Protected Sub btnConvert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnConvert.Click
If txtVB.Text IsNot Nothing Then : txtVB.Text = "" : End If
Dim input() As String = txtSQL.Text.Split(vbCrLf)

VS 2008 Producing A Log From A Command Line That Does Not Produce One

Sep 22, 2009

I need to parse a log file from some information provided via an external command line application. The problem is that the command line app doesn't produce its on logs. So, I was wondering how I might be able to obtain the information form the command line. The only thing I could think of was to redirect the output to a TextBox, write it to a text file and then parse the data. Does anyone know of any other to do this?

VS 2008 Updating Database - Producing Duplicate Values

Jul 29, 2009

Here is my

cn.Open()
Try
str = "UPDATE Products SET ProductCode = ?, ProductManufacturerCode = ?, ProductsTitle = ?,
[Code] .....

If there is only one item in the database, then this code works. If there is more than one record then the error is produced that it is trying to produce duplicate values. This is down to the Primary key in my database which is the only thing that cannot have duplicate values. However, when I remove the primary key it has the predictable problem that it goes crazy and does weird things.

I'm currently moving over to W7 from Vista I've moved my source over (amazingly hassle free), but the Build option on my installer in my solution produces a different size (200K+) setup.exe file.

Initial question are:

1) Is there a log file I can compare betwen the two builds (V7 -v- Vista)

2) I thought that any compiler settings would 'follow the solution' Is this so?
