At my job they asked me if it would be able to build a program with 4 sepperate forms, that would switch to forground every 30 seconds.
So that first form1 is on top, 30 seconds later form 2.
I am not a prof-programmer and I do is as a hobby so thats why this question.
I managed to do this but then I had to include thread.sleep but then the form hangs. When I use a Timer to call the forms, after they all have been opened, it comes up with cross-threading.
I dont have any code at this moment to present you guys so sorry for that. but what is the best way to do this?
I start the application and press a start button.
It opens screen1.cs with some information/pictures ect on it.
After 30 seconds it opens screen2.cs with also info
30 secs later... screen 3.cs
and again 30 secs later, screen 4.
____
| Now I need it to set screen1.cs back to topmost, 30 secs later screen2 ect. ect.
| This will make sure that first screen1 and then ... is topmost so they switch positions
|-->this will be the loop
I dont know if this is the best way, or that there is a much easier way to do this. I hope you guys know what I exactly mean. I do not know much about threads, im still working on that so sorry for that.
Thanks in advance,

using System;
using System.Drawing;
using System.Windows.Forms;
public class Form1 : Form
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
public Form1()
{
timer1 = new Timer();
timer1.Interval = 2000; // 2 seconds because I'm not waiting around for 30
timer1.Tick += timer1_Tick;
Button button = new Button { Name = "button1", Text = "Click To Start", Location = new Point(10, 10), AutoSize = true };
button.Click += button1_Click;
Controls.Add(button);
for (int n = 1; n <= NumberOfPanels; n++)
Controls.Add(CreateGenericUserControl(n));
}
private Control CreateGenericUserControl(int number)
{
Control control;
control = new UserControl { Name = "userControl" + number.ToString(), Dock = DockStyle.Fill, Visible = false };
control.Controls.Add(new Label { Text = control.Name, Location = new Point(10, 10) });
return control;
}
const int NumberOfPanels = 4;
private int currentPanel = 1;
private Timer timer1;
private void button1_Click(object sender, EventArgs e)
{
Controls["button1"].Visible = false;
Controls["userControl" + currentPanel.ToString()].Visible = true;
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
Controls["userControl" + currentPanel.ToString()].Visible = false;
currentPanel++;
if (currentPanel > NumberOfPanels)
currentPanel = 1;
Controls["userControl" + currentPanel.ToString()].Visible = true;
}
}

I wouldn't do this with forms, it makes no sense. Instead create four user controls, add them all to one form and hide/show them as appropriate. | | Tergiver Saturday, September 12, 2009 5:44 PM | Tergiver offers some good advice. Check out this thread for a different approach. A TabControl with invisible Tabs, using borderless forms.
