I'm trying to write a virtual piano program. Each key plays a sound from the resources directory.How do i play two(or more) sounds at the same time if ex two keys are pressed. Or start playing another sound while one is still playing.
View 2 RepliesI have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:
Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub
The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.
The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?
I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.
I have used DirectSound to play a wave file in my application using the function CreateSoundBufferFromFile. It works perfectly.Now I want to play files from a resource dll file. I have created 1n2v32.dll file having nearly 100 small wave files named 1,2,3... I can play them using LoadLibraryEx, PlaySound & FreeLibrary.Now, I am trying to use CreateSoundBufferFromResource function from DirectSound api to play these files. I get Run-time error '432': File name or class name not found during Automation operation I used the following code to create the buffer.
Set LDSB = LDS.CreateSoundBufferFromResource(App.Path & "1n2v32.dll", "14", BufferDesc, gw)
I'm trying to make a "Simon" game with four buttons labeled 1-4. The game is supposed to read the numbers out loud, but i have a problem with that. I have 4 wav files from google text-to-speech, each named 1-4. I made an number generator that can return like this "42331", and the game is supposed to play 4.wav, 2.wav, 3.wav, 3.wav and 1.wav.
Here's what I got so far.
Public Class Form1
Dim rnd As New Random
Dim i = 0
Dim level As Integer = 5
Dim nums As String
[code] .....
It only plays 1.wav (the last in the sequence).
how can i get it to play other files besides just .wav, like .mp3. wave files are way too large to be used easily if you want a good quality. why cant i play .mp3 files with it?when i convert a 2.1 mb mp3 file to .wav it turns out to be 36 mb?any other ways besides computer.audio to play audio files on command?
View 1 RepliesHow can I create a GUI in vb.net similar to the one above?i.e.there are "buttons" on the left which changes the main window when they are clicked.One way I thought of is create many panels overlapping and show/hide them when a certain button on the left is clicked.
View 2 RepliesI have a sub-procedure which I want to run a different process, depending on what is currently running. I thought the easiest way to do this was by using an ArrayList of each of the campaign details & adding an 'Inuse' field to check to see if the Inuse field is set to 0 or 1. The problem that I have is that when running the process it is all happening at once & the integer hasn't been changed before the next thread kicks in so my threads are running the same campaigns. I tried to avoid the problem by adding a Thread.Sleep(100) delay inbetween starting threads but this led to exactly the same problem.
Here's an example of what I am trying to do:
Imports System.Threading
Public Class Form1
Private Campaigns As New ArrayList
Private ProcessRunning As Boolean = False
Friend StopProcess As Boolean = False
[Code] .....
How could I...
- Increase the frequency of every part of a wave file by a specified amount of Hz
- Increase/decrease the length of a wave file without reading it faster = changing the pitch
- Combine many wave files into one
I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
Is it possible to stream more than two sounds simultaneously in .NET without using DirectX?
To obtain foreground and background effects I currently use the following:
' Background music
Private bkMusic As New SoundPlayer(My.Resources.bkm)
[CODE]..................
SoundPlayer is a wrap around to the win32 API:
Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long
While for actual in game sound effects I am using a class that implements:
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpszCommand As String, ByVal lpszReturnString As String, ByVal cchReturnLength As Long, ByVal hwndCallback As Long) As Long
It works. 1 snd effect at a time overlapping / mixing with the background music. But I am on the hunt for a better method which allows me to stream multiple snd effects simultaneously. DirectX is not an option, because most people (my audience) don't have the SDK (software development kit)
Based on a thread earlier today, and in particular an answer that Cor gave wherein he
pointed to this article, I thought that I'd do some investigation. Many times here the question has come up about playing .mp3 audio files and NOT using the Windows Media Player object. In the article referenced above, he shows how this can be done via DirectX.
I've looked at DirectX before and it seemed ambiguous so I never really dug into it but it turns out to be pretty simple actually! I thought that I'd write this as a step-by-step of what I did so that maybe some of you will find use from it. The whole thing stems around using DirectX and to begin with, you'll need to download and install the SDK for it. If you haven't already,
try this link. Do be aware that it's a large download (about a half gig)! Once that's installed, create a form and add a reference to the class that we need for this. You can do this several ways, but the way I usually do is to right-click on the name in the Solution Explorer, then choose "Add Reference":

I want to play MP3 Files directly from the internet. I don't want to use other applications, like WMP, just my application.

This is tied in with the other discussion that I started last week about playing audio files using the DirectX classes. If you haven't yet had a look at that other thread,Using the same reference as in the audio application, let's set up a form for video this time. I started with a form that I then placed a split container on and in the lower panel of the split contatiner, I placed the buttons and other controls. Following is how I have mine set up:
Reread the thread on the audio player because the methods are very similar - in fact some are identical! However, this is video and it got a bit more involved as you might expect.The full code is here and I hope you'll find it useful to you. Following is a screenshot of the end result.

View 1 RepliesIs it possible to play 8 different and individual mono wave files to a 7.1 (8 channels) audio system using vb.net? (I undestand that the .1 speaker is the subwoofer and I'm not yet sure it can be replaced with an ordinary speaker.) The playing should start simultaneously and the files can be of different size/length.Is this something that should be done using win API functions if it can be accomplished at all.I just re-installed my old VB6 which I need to ugrade and vb.net would be the easiest for me so I placed this Q here.
View 2 RepliesI am working on an application in VB.net (.NET 2.0) where I need to open a dynamic amount of different audio streams. Normally, for audio files, one would suggest importing the Windows Media Player COM reference and adding a GUI-based element from the toolbox, but since I'll be working with a dynamic amount of these a GUI would be a terrible idea (especially with Tab stops).

View 18 RepliesWe have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?
Been doing VB2010 for about a year now, have recently started to push the boundary's for what kind of media I can incorporate into my forms. I haven't been able to play .wav or .mp3 files though. I have tried to follow tutorials on microsoft and other coding websites without success.

I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.
Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.
