After a video file ends, how would I get the next video to play without setting a timer?

I have put together a list of files that I want played from a specific directory. The videos/pictures are displayed on Windows Media Player. After the end of one video, I want the play button to be pressed to play the next video. Currently, my code is set up to have a button pressed to go to the next file in the list, as well as a play button being pressed to display the image (buttons are pressed using a timer, but this is inconvenient because some videos do not get played for the full time). Video URLS are pulled from textboxes that are filled with xml or file path information.
private void Form1_Load(object sender, EventArgs e)
{
axWindowsMediaPlayer1.stretchToFit = true;
axWindowsMediaPlayer1.uiMode = "none"; //disables the play, pause, etc. buttons at the bottom of the windows media player//
listView1.Items.Clear(); //clears listview items//
Repopulate(); //calls repopulate function//
refreshtimer.Interval = 5 * 60 * 1000;
//timer for when images need to be displayed//
Timer tmr = new Timer();
int result = int.Parse(textBox2.Text);
tmr.Interval = result * 60 * 1001;
tmr.Tick += new EventHandler(timer1_Tick);
tmr.Start();
}

If a timer is the most practical element to use, what would be a better way to implement it?

so I was trying to make a code that changes the writings font(arial,times new roman etc.) in the textbox every 750 miliseconds but I couldn't do it

private void OnTimer(object sender, EventArgs e)
{
int i = 0;
i += 1;
}
I tried to make the timer
private void Form1_Load(object sender, EventArgs e)
{
int i = 0;
FontFamily[] fontlar = FontFamily.Families;
fontlar.GetUpperBound(i);
Timer timer1 = new Timer
{
Interval = 750
};
timer1.Enabled = true;
timer1.Tick += new System.EventHandler(OnTimer);
}
I put the code in form1 but I tried it in textbox as well it didn't work
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
}
button

I guess you are new to this.
Your Timer does nothing
Your Timer is local, it should be public
You didn't create your Textbox
I think this would be your answer:
Timer timer1;
int i = 0;
private void Form1_Load(object sender, EventArgs e)
{
timer1 = new Timer
{
Interval = 750
};
timer1.Enabled = true;
timer1.Tick += new System.EventHandler(OnTimer);
}
private void OnTimer(object sender, EventArgs e)
{
i += 1;
FontFamily[] fontlar = FontFamily.Families;
//fontlar.GetUpperBound(i);
textBox1.Font = new Font(fontlar[i], 16.0f);
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
}
Don't forget to create a textbox on your form.

what is the way to close the form and open it again

i try to close the from and open it again with this code bout it didn't close the form i found it in the background and open another one for it
private void Graph_Load(object sender, EventArgs e)
{
System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();
timer1.Interval = 60000;//1 minutes
timer1.Tick += new System.EventHandler(Timer1_Tick);
timer1.Start();
}
private void Timer1_Tick(object sender, EventArgs e)
{
//do whatever you want
RefreshMyForm();
}
private void RefreshMyForm()
{
this.Close();
Graph1 graph = new Graph1();
graph.Show();
}
start refresh is what i looking for

All you have to do is to change RefreshMyForm() to Refresh(); and clear function RefreshMyForm().
private void Graph_Load(object sender, EventArgs e)
{
{
System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();
label1.Text = DateTime.Now.ToString("HH:mm:ss");
timer1.Interval = 60000;//1 minutes
timer1.Tick += new System.EventHandler(Timer1_Tick);
timer1.Start();
}
}
private void Timer1_Tick(object sender, EventArgs e)
{
label1.Text = DateTime.Now.ToString("HH:mm:ss");
Refresh(); // OR Invalidate(); OR Update();
}
Here label1 is simple watch to see how form refreshed every minute

C# button animation

i have a simple two button:
button1
button2
i want when click on button1 the button2 start a move to right,
i write this code:
private void button2_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
timer1.Interval = 100;
}
private void timer1_Tick(object sender, EventArgs e)
{
button1.Left += 20;
}
private void button3_Click(object sender, EventArgs e)
{
timer1.Enabled = false;
//timer1.Interval = 0;
}
i want when the button exit on my form border on right side,timer has stop the animation.

I think this is what you looking for:
private void button2_Click(object sender, EventArgs e)
{
timer1.Interval = 100;
//start the timer
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
button1.Left += 20;
//check position of button. When it is outside the width of form stop the timer.
if(button1.Left >= this.Width)
{
timer1.Stop();
}
}

How to make Trackbar works while media is playing

I am working on a simple mediaplayer application. It works great but I want to add some extra features. I have added a trackbar control.How can i set trackbar length the same as the music's length ?
Like if the song is halfways the trackbars halfways.This is what I have so far
string[] files, indexed_files;
private void button3_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK) {
files = ofd.SafeFileNames;
indexed_files = ofd.FileNames;
for (int i = 0; i < files.Length; i++)
{
listBox1.Items.Add(files[i]);
}
}
button4.Enabled = true;
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
axWindowsMediaPlayer1.URL = indexed_files[listBox1.SelectedIndex];
progressBar1.Maximum =(int) axWindowsMediaPlayer1.currentMedia.duration;
axWindowsMediaPlayer1.PlayStateChange += axWindowsMediaPlayer1_PlayStateChange;
}
void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
trackBar1.Value = (int)axWindowsMediaPlayer1.Ctlcontrols.currentPosition;
}
int index = 0;
private void button4_Click(object sender, EventArgs e)
{
if (listBox1.Items.Count != 0) {
axWindowsMediaPlayer1.URL = indexed_files[index];
trackBar1.Maximum = (int)axWindowsMediaPlayer1.currentMedia.duration;
index++;
index = (index % listBox1.Items.Count);
}
}

This will bring you the desired outcome.In my example i just placed the url in the form load for demonstration purposes.The openstatechanged event its to set the trackbar maximum since you need to wait for the player to load the file,after that the code its pretty self-explanatory:
public partial class Form1 : Form
{
Timer t;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
axWindowsMediaPlayer1.URL = "YourUrlHere";
t = new Timer();
t.Interval = 1000;
t.Tick += new EventHandler(t_Tick);
}
void t_Tick(object sender, EventArgs e)
{
trackBar1.Value = (int)this.axWindowsMediaPlayer1.Ctlcontrols.currentPosition;
}
private void axWindowsMediaPlayer1_OpenStateChange(object sender, AxWMPLib._WMPOCXEvents_OpenStateChangeEvent e)
{
if (axWindowsMediaPlayer1.openState == WMPLib.WMPOpenState.wmposMediaOpen)
{
trackBar1.Maximum = (int)axWindowsMediaPlayer1.currentMedia.duration;
t.Start();
}
}
}
Yes its a timer:),and probably it is best to set it bellow 1000 for reasons of delay.

So you should now add a timer and insert the following code in timer Tick event handler:
trackbar.Value = this.axWindowsMediaPlayer1.ctlControls.CurrentPosition;
