problem with Csharp

Ok thank you Vulpes :)

It's a good idea as long as the folder you've added ends up in the same place relative to the .exe folder when you install the application on a user's machine. As you're using:

string chemin = "..//..//Sequences//alarme.wav";

then the folder always needs to be two levels higher in the directory tree than your .exe.

I think it's installation problem .

Hello
now i can read my sound file in any pc but I didn't use System.Resource.ResourceReader
This is my code:

System.Media.SoundPlayer sp = new SoundPlayer();
private void button1_Click(object sender, EventArgs e)
{

//Dans ton constructeur :

string chemin = "..//..//Sequences//alarme.wav";
sp.SoundLocation = chemin;
sp.LoadCompleted += new AsyncCompletedEventHandler(sp_LoadCompleted);
sp.LoadAsync();
}

//Puis
private void sp_LoadCompleted(object sender, AsyncCompletedEventArgs e)
{
sp.PlayLooping();
}


I created a new folder: "Add" -> "New Folder" -> my folder name is Sequenes ->than I clicked on Sequences -> "Add" -> "Existing Item"-> I added alarme.wav

Did you think that it's a good idea?

For everyone trying to help Nicole, note that her actual requirements are a bit advanced. The following is based on prior discussions with Nicole and I assume this remains to be the eventual requirements.

She needs to be able to select a microphone from multiple microphones and also select a speaker from multiple speakers and then stream the output of the selected microphone to the selected speakers. Her requirements might have changed but if they are the same as before then that is what she needs to do. Can System.Media.SoundPlayer do that?

I hope Nicole can confirm whether her current requirements are as they were in the past or if they have changed.

Well, that code is including the image files as a resource and you could certainly do that with the sound files.

I was thinking before that, even if you did that, you'd still need to stream the files to disk so that you could set the SoundLocation property to the appropriate file path.

However, I've been looking at the documentation for the SoundPlayer class and there's a Stream property which may allow you to set it directly to the resource stream without having to save to disk first.

I found this code in the net (in this version it give us the possibility to insert an image and I think that we can use it if we change the image file by a sound file,do you think that it can works?):

Incidentally, if you do go with the idea of installing the files in a sub-folder of the application's folder, then you can get the full path to a file on the user's machine as follows:

string filePath = Application.StartupPath + "\\wavfiles\\"  + whatever.wav; 

That's why my first suggestion was to display an OpenFileDialog so that the user could select the file from his/her MyMusic folder. 

Failing that you're going to need to install the sound files (say, in a sub-folder of the .exe's folder) when you install your application on the user's machine. Otherwise they could be anywhere, if indeed they're installed at all!

Hi Vulpes :)

In my application the user shouldn't chose a sound file,it should be related to the button.I mean when I select the button I can hear the specific sound.

Hello guys
Now I can read a sound file, I found this code in the net and I tried to correct it using your advices:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.DirectX.AudioVideoPlayback;
using System.Runtime.InteropServices;
using System.Media;

namespace alarmee
{
public partial class Form1 : Form
{
public Audio Lecteur;
public bool lecture = false;
public Form1()
{
InitializeComponent();
}
[System.Runtime.InteropServices.DllImport("winmm.DLL", EntryPoint = "PlaySound", SetLastError = true, CharSet = CharSet.Unicode, ThrowOnUnmappableChar = true)]
private static extern bool PlaySound(string szSound, System.IntPtr hMod, PlaySoundFlags flags);

public enum PlaySoundFlags : int
{

SND_LOOP = 0x0008,
SND_NOSTOP = 0x0010,
SND_NOWAIT = 0x00002000,
SND_FILENAME = 0x00020000,
SND_RESOURCE = 0x00040004
}

private void button4_Click(object sender, EventArgs e)
{
}
System.Media.SoundPlayer sp = new SoundPlayer();
private void button1_Click(object sender, EventArgs e)
{

//Dans ton constructeur :
sp.SoundLocation = "C:\\Sample\\alarme.wav";
sp.LoadCompleted += new AsyncCompletedEventHandler(sp_LoadCompleted);
sp.LoadAsync();
}

//Puis
private void sp_LoadCompleted(object sender, AsyncCompletedEventArgs e)
{
sp.PlayLooping();
}}}



Now I want to read the sound file witout precising its location because it's not practical to demand to a person who want to use my application to have the same file.wasv in the same location.
Hope you can understand what I wrote.
Thank you in advance
Good day

to play a sound

using System.Media;

private void button1_Click(object sender, EventArgs e)
{

SoundPlayer simpleSound = new SoundPlayer(audio file to play eg "sample.wav");
simpleSound.Play();
}

Your problem is
using Microsoft.DirectX.AudioVideoPlayback;
It runs in c# 2008 but not C#2010

I found the application configuration file,I added this lines :



but I still having the same problem,Sorry if i'm bothering you but I really need your help

While adding it's not like App.Confige select Application Configuration File from add new item dialogue.

Hi Nicole,
Go to solution explorer, right-click on it and say add new item and select app.config from the list.

Thank you Mamta but I didn't understand your answer,where i shiuld add this lines and what's "config file, ie, App.config file"
where I can find it???????

DirectX assemblies are mixed mode therefore you need to add the following  lines to your application config file, ie, App.config file

As per the translation of the error message, it indicates that you had created an earlier code on an old runtime and are now trying to run it under .NET Framework runtime 4.0. But the code is not compatible with the new version. Therefore, I suggest that you create a new project in Visual Studio 2010 and copy only your C# code into that project. Then, compile it .

From your explanation I think your project contain one of the assembly from third party which is not installed on your system. For verification just check out the references are ok or not.

Hi,
Please let me knpw what exacly you are doing. Where you are getting the error.
