Accessing the resources in the published application

I followed a tutorial on Video Player.

It is nice but I am imagining a different situation.

I need to embed some videos in the Resources file and dynamically change the videos depending on the user input. I have managed this running inside Visual Studio 2010. using the switch statements. But I have to specify the path of that video in the resources file. for eg :

case 1 : video = new Video("..//..//Resources//The video name");

But when I publish this application using the click once wizard, the final application ends up in an exception :

System.NullReferenceException: Object reference not set to an instance of an object.
   at VideoPlayer.Form1.button2_Click(Object sender, EventArgs e)
   at System.Windows.Forms.Control.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnClick(EventArgs e).............

It seems that the video file was not included in the application. But when i saw the installer folder, a clear look showed that there is a file as named VideoPlayer.exe.deploy which is of 59MB normally these files without any resources are light weighted...

It surely contains the Video file. But I cannot access that file.

How Do I Access It?

Please help me out...

Thanks in advance :-)

As asked by some users, I am posting the entire code in C#.NET :

The Designer.cs File :

        /// </summary>

        /// <summary>

        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();

And I thought a screenshot may be of some information :

It works fine in Debugging mode..... But once I install it using the click once installer, It crashes into an Exception. How do I manage the same using the Resources in the DEPLOY file?

You are referencing the files in your VS solution, which works fine, when debugging the application, since the paths are valid from your project's \bin\debug folder. If you've set the build-action for the resources to "Embedded Resource", you can access those files using:

typeof(Form1).Assembly.GetManifestResourceStream("PlayVideo.Resources.Video1.dat");

MSDN: http://msdn.microsoft.com/en-us/library/xc4235zt.aspx

Update I've confirmed that the Video class won't accept a Stream and that the res://-Protocol cannot be used either. I would suggest, that you don't embed the videos into the executable, but place them into the Application directory. You can change the build-action of the video-files to none and change the "Copy to Output Directory" property to "Copy If Newer". Once the application is built, all videos are put in the output directory, which you can deploy along with the executable. You should then use your initial approach, but use a path like "The video name.dat" rather than "..//..//Resources/The video name.dat".
