✅ would like help to fix my timer for windows forms

Hi, I’m in college and am working on my final project, I’m experiencing an issue with my timer (“no overload for ‘timer1_Tick’ matches delegate ‘EventHandler’”) in my windows form design, I am also looking to redo my project with instantiation to make it more efficient, help would be very much appreciated 👍🏼👌 (Only properly started using C# a few months ago)

That means its signature doesnt match the delegate type EventHandler lets check what signature the timer tick event has public delegate void EventHandler(object? sender, EventArgs e); Do you see the difference?

Embarrassed to say I don’t really know lol?

object? vs object try slapping a questionmark at the end of object in your timer1_Tick method only thing I can think of, because otherwise it looks valid to me also, your while loops are just for loops :p

lol I know It’s an on going joke with my teacher But yeah it still isn’t happy with me ),:

verify that you dont have two timer1_Tick methods

KiragiOP•11mo ago

I don’t think so Find command, only shows the one

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {

    }
}

//designer.cs
timer1 = new System.Windows.Forms.Timer(components);
SuspendLayout();
// 
// timer1
// 
timer1.Tick += timer1_Tick;

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {

    }
}

//designer.cs
timer1 = new System.Windows.Forms.Timer(components);
SuspendLayout();
// 
// timer1
// 
timer1.Tick += timer1_Tick;

works fine here are you sure its not a ghost problem?

Pobiega•11mo ago

KiragiOP•11mo ago

No errors Hopefully it works now

Pobiega•11mo ago

okay, then its likely a ghost error, meaning VS cached the error and missed that you fixed it

KiragiOP•11mo ago
