Question

I am trying to create a Windows Form application to play .WMV files.

I have 5 videos that i have added to my project, within a Videos folder.

I have created a button for each video, 5.

When a button is clicked, Button1, i want to be able to open Video1.. Using Windows Media Player for example.

Code so far::

    private void PlayVideo1_Click(object sender, EventArgs e)
    {
        // Open Windows Media Player
        System.Diagnostics.Process.Start("wmplayer.exe");

        // Play Video1.
        Process.Start("Video1.wmv");
    }

Please can you advise what i am doing wrong?

========================

Update:

Can a similar code be used for WPF?

Answer 1

Is the WMV files set to “Copy always” in the “Copy to output Directory” property? Like in the picture below:

If it is, then the files are going to the same directory as the application, the next step is to run the WMV from the propert path,

Your code:

Process.Start("Video1.wmv");

Is not wrong to want to start the WMV directly (that way, the default player in the target machine will run), but you need to send the full path (C:\Video.WMV for eg)

If the WMV files are inside a VIDEOS folder within your application, you could change to do like this for eg:

Process.Start(Path.Combine(Application.StartupPath, "VIDEOS/Video1.wmv"));
