What is the correct way to add files to the Resources of a VB.net project

I have been having trouble getting wave files into the resources of this project.

I tried to add the wave files by right clicking on 'Resources' in the Solution Explorer and selecting 'Add' and 'Existing Item'

That added the files to the Resources list but I couldn't select it with code.

I restored my files by loading a copy of a backup to ensure that there were no problems with project and then tried a different way to add the wave files.

I opened Resource Explorer by clicking on 'View', hovered over 'Other Windows' to open the next list where I clicked on 'Resource Explorer'.

After opening Resource Explorer I clicked the green + symbol which opened the 'Add New Resource to Form1' window.

In this window I changed the Type to audio.

I clicked on 'Select File' navigated to the folder and then selected the 'Alarm01.wav' file.

To ensure I had a valid and working .wav file I copied the 'Alarm01.wav' file from C:\Windows\Media folder to another, which will play directly from the folder using the 1st line in the Button1 _Click event.

The Name field took on the name of the file and the only option for 'Add To File' was 'Form1' so I didn't change these.

The file showed up under the 'Resources'

I then tried adding the resource to the same code that would play the file from it's original folder this is the 2nd line in the Button1 _Click event, but I keep getting the same result, My.Resources.Alarm01 is underlined in red with the error 'BC30456: 'Alarm01' is not a member of 'Clock_App_V1.2.MyResources'.

There is more code for the mediaplayer but this is all that was needed to play the sounds.


    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        FullAlarmFilePath = "D:\Desktop\New folder\Alarm01.wav"
        'FullAlarmFilePath = My.Resources.Alarm01.ToString
        'FullAlarmFilePath = My.Resources.AarrowUp2.ToString
        PlaySound()
    End Sub

    Private Sub PlaySound()
        AxWindowsMediaPlayer1.URL = FullAlarmFilePath
        AlarmSounding = True
        AxWindowsMediaPlayer1.Ctlcontrols.play()
    End Sub

As an experiment I added another line, the 3rd line in the Button1 _Click event which selects a bitmap image to play, but I didn't get the error '<name>' is not a member of '<classname>'.

Obviously if I clicked on the button to play it then mediaplayer would tell me that it wasn't the correct format.

This showed me that the bitmap was considered as part of the resources and that I could select it when typing the code, but I can't select Alarm01.wav that is part of the same resources.

I remember having the same problem a long time ago with images and found that if I added them by using the background image of a control, such as a button or picture box it would work.

That is how I have been adding images ever since and is how I added the image used in the code.

So I tried adding a bitmap the same way as I added the audio and found that it gives the same result, when writing code it doesn't recognise that the bitmap is there.

It must be something to do with how I'm adding the files.

Does anybody know what I am missing or doing wrong, because I can't see what it could be.

Try another king of resources.

Right-click the project in Solution Explorer, go to Add, New Item, and add the “Alarm01.wav” to project.

Select the added “Alarm01.wav” in Solution Explorer, right-click, go to Properties (or press <F4>). Set “Copy to Output Directory” to “Copy if newer”.

Use this code:

private void button1_Click( object sender, EventArgs e )
{
    axWindowsMediaPlayer1.URL = Path.Combine( Application.StartupPath, "Alarm01.wav" );
    axWindowsMediaPlayer1.Ctlcontrols.play( );
}

Thank you once again Viorel.

It isn't quite what I had in mind but it worked with a little alteration.

I had to add '\Resources' to the path to get it to work.

axWindowsMediaPlayer1.URL = Path.Combine(Application.StartupPath & "Resources", "Alarm_01.wav")

This isn't an App that I would pass on to others, it's purpose was for learning.

I wanted to have a default sound contained in the App that a user could not delete, and consequently break the App.

Doing it this way it appears that the user can do exactly that, well not break it, but the media player will throw an error if the file is deleted.

At least it appears that the file goes with the APP, so I'm half way there.I will probably leave it at that since the most important part was to have the file contained in the App.

Hi there,

I am also struggling with the exact same issue BC30456.

{5608BC39-743C-4AA3-A71B-E4FB7CB410CB}

This code used to work in older versions of Visual Studio 2022. I did try VS 2026 and I get the same problem.

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        My.Computer.Audio.Play(My.Resources.win, AudioPlayMode.BackgroundLoop)
    End Sub
End Class

I have added the Audio file in my resources:

{CE69AD05-9484-498D-8B16-F47A8F206293}

I can definitely see the audio in the Resources foder:

{FF6679DA-8F30-4DC7-9512-3EE53E9E8B7F}

I even tried to change 'Build Action' from 'None' to 'Resource', but still does not think my audio file is a member of my project...

{E8BD7787-DAD2-40AE-869A-3B95631407C4}

I am using:

Microsoft Visual Studio Professional 2022 (64-bit) - Current, Version 17.14.31 (April 2026)
with Microsoft .NET Framework Version 4.8.09221.

Please help.

Thank you.

If a file is added as a resource, it is not a separate file, but part of the exe. The contents are available as a stream via the generated resource manager code. Pass the stream instead of file name.

Thank you Bruce.

I think what you have suggested is what I was looking for, but unfortunately it is beyond my capabilities at this time.

I'll come back to this later as I learn more.

To correctly add audio files like .wav files to the resources of a VB.NET project, follow these steps:

Open Resource Explorer: In Visual Studio, go to View > Other Windows > Resource Explorer.
Add New Resource: Click the green + symbol to open the Add New Resource to Form1 dialog.
Select Type: Change the type to Audio.
Select File: Click on Select File, navigate to your .wav file (e.g., Alarm01.wav), and select it.
Name the Resource: The name field will automatically take the name of the file. Ensure that the Add To File option is set correctly (it should be set to the form where you want to use it).
Check Resource Access: After adding the resource, you should be able to access it in your code using My.Resources.Alarm01.

If you are encountering the error 'Alarm01' is not a member of 'Clock_App_V1.2.MyResources', it could be due to:

The resource not being properly added to the project. Ensure you see it listed under My.Resources.
The resource name might not match what you are trying to access in code. Check for any typos or case sensitivity issues.
If you added the resource in a specific form, ensure you are accessing it from that form's context.

If you still face issues, consider removing the resource and re-adding it, ensuring you follow the steps correctly. Also, check if the project is properly built after adding resources, as sometimes changes may not reflect until a rebuild is performed.
