Play WAV file from embedded resources.
-
Hi all, I "add" a wav file to my project "file.wav" and made it embedded resource. now i have seen here and micosoft code to read and play it but its not working..what am i doing wrong? my code:
private byte[] m_soundBytes; private enum Flags { SND_ASYNC = 0x0001, SND_MEMORY = 0x0004, } [DllImport("winmm.dll",CallingConvention = CallingConvention.Winapi)] static extern int PlaySound(byte[] wfname,int hMod,int sf);then there is the class WSounds:public WSounds(string s) { string sss = Assembly.GetExecutingAssembly().GetName().ToString(); Stream a = Assembly.GetExecutingAssembly().GetManifestResourceStream(sss + "." + s); m_soundBytes = new byte[a.Length]; a.Read(m_soundBytes, 0, (int)a.Length); } public void Play() { PlaySound(m_soundBytes, 0, (int)(Flags.SND_ASYNC | Flags.SND_MEMORY)); }this line throws exception : m_soundBytes = new byte[a.Length]; so i guess something with the resource is wrong.. i tried another code too:System.IO.Stream strTheme = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("file.wav"); byte[] bytTheme = new byte[strTheme.Length]; strTheme.Read(bytTheme, 0, (int) strTheme.Length);by the way: how do i need to add a WAV file ? under resources sub-dir or on the main project? Thanks in advance, Ran R.Z -

Thanks in advance, Ran R.ZI had troubles with exactly this stuff last week.

The
Stream ais probably null, because the assembly couldn't fine the resource."file.wav"won't work either, because you have to prefix the file.wav with the project namespace (at least in VB.Net). You can dostring[] names = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();
foreach (string name in names){
Debug.WriteLine(name)
}and look for the name you want (this is the way i did it :)).

That doesn't matter. Whatever the folder may be, it doesn't matter for the compiler, just like C# source files. HTH! :)

You have to do it in C#, too. <smile /> "we must lose precision to make significant statements about complex systems." -deKorvin on uncertainty

Hi, Its very complicated to see the code,, so please post ur sample piece of code, and also post what is the problem u are facing and whts the solun you found.. its useful for all the beginners as well as developers.. Bye

the final code is:
using System; using System.Runtime.InteropServices; using System.Diagnostics; using System.Threading; using System.IO; using System.Reflection; namespace yournamespace { public class WSounds { private byte[] m_soundBytes; private bool disable=false; private enum Flags { SND_ASYNC = 0x0001, SND_MEMORY = 0x0004 } [DllImport("winmm.dll",CallingConvention = CallingConvention.Winapi)] static extern int PlaySound(byte[] wfname,int hMod,int sf); public WSounds(string s) { if (s == null) { disable = true; return; } try { Stream a = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(s); m_soundBytes = new byte[a.Length]; a.Read(m_soundBytes, 0, (int)a.Length); } catch (Exception e) { disable = true; } } public void Play() { if (!disable) PlaySound(m_soundBytes, 0, (int)(Flags.SND_ASYNC | Flags.SND_MEMORY)); } } }then in your main code you must add a file to your resources list "file.wav" for example that will be along the classes..and change his property to :"embedded resources" so it will compile him along with the exe. and you call the class this way:private WSounds ws; ws = new WSounds("yournamespace.file.wav"); ws.Play();thats it.
