Im making a tabbed web browser, everything is going smooth exept one thing.
If you try to delete the tab when there is only 1 left, the browser breaks.
I know how to fix it… i hide my delete tab button when there is only one tab (when i is 1). It dosnt hide the button though.

Just to let you know my browser starts with the button hidden.
I want to hide the button after you click the delete tab button when i is 1.
How would I do that?

I tryed

if (i == 1)  button2.Hide(); 

It compiles, but dosnt work.

if(i == 1)
{

button2.hide();
}

Try that.

That looks so close to php code Josh :D.

Yep, but it's C# :).

They kinda look alike though.

From: Buckleyindahouse
if(i == 1)
{

button2.hide();
}

Try that.

Still not working :/
Compiles but dosnt work.

Looks like Java

post more of the source code?

I could probably help.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        int i = 1;
        public Form1()
        {
            InitializeComponent();
        }

        private void pictureBox3_Click(object sender, EventArgs e)
        {
            ((WebBrowser)tabControl1.SelectedTab.Controls[0]).Navigate(textBox1.Text);
        }

        private void tabPage1_Click(object sender, EventArgs e)
        {
           
        }

        {
            WebBrowser Browse = new WebBrowser();
            tabControl1.TabPages.Add("Page " + i);
            tabControl1.SelectTab(i - 1);
            Browse.Name = "wb";
            Browse.Dock = DockStyle.Fill;
            tabControl1.SelectedTab.Controls.Add(Browse);
            ((WebBrowser)tabControl1.SelectedTab.Controls[0]).GoHome();
            i = i + 1;
            button2.Hide();
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            ((WebBrowser)tabControl1.SelectedTab.Controls[0]).GoBack();
        }

        private void pictureBox2_Click(object sender, EventArgs e)

            ((WebBrowser)tabControl1.SelectedTab.Controls[0]).GoForward();
        }

        private void pictureBox4_Click(object sender, EventArgs e)
        {
            ((WebBrowser)tabControl1.SelectedTab.Controls[0]).Refresh();
        }

            tabControl1.TabPages.Add("Page " + i);
            tabControl1.SelectTab(i - 1);
            Browse.Name = "wb";
            Browse.Dock = DockStyle.Fill;
            tabControl1.SelectedTab.Controls.Add(Browse);
            i = i + 1;
            button2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveAt(tabControl1.SelectedIndex);
            tabControl1.SelectTab(tabControl1.TabPages.Count - 1);
            i = i - 1;
            //If i is 1 it should hide
        }

        private void Form1_Activated(object sender, EventArgs e)
        {
            
        }
    }
}

Thats my whole source so far.

At the top, change int i to


Public Static Int i = 1;

See if that works if not, i'll look at source again.

I got it working without changing anything.
All i did was make

private void button2_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveAt(tabControl1.SelectedIndex);
            tabControl1.SelectTab(tabControl1.TabPages.Count - 1);
            i = i - 1;
            if (i == 2) button2.Hide();
        }

Instead of

private void button2_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveAt(tabControl1.SelectedIndex);
            tabControl1.SelectTab(tabControl1.TabPages.Count - 1);
            i = i - 1;
            if (i == 1) button2.Hide();
        }

Left i as an int.
Now I have to find out why button2 hides when i is 2 and not 1

Try

private void button2_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveAt(tabControl1.SelectedIndex);
            tabControl1.SelectTab(tabControl1.TabPages.Count - 1);
            i = i - 1;
            if (i <= 1) button2.Hide();
        }

Heh, you using C# Express Edition 2008 or what? I prefer VS2008 Pro for C# :P

– BP

button2.visible = false; // hides the button

button2.enabled = false; // disables the button

Or just try to debug the value of I, see if it results 1

Finally something about C#, is it already fixed -.-.
Btw, if I were you I would do something different.
I would make a custom component and then use an array of it then loop through it and place them on the form and you should make them smaller and wider if needed ;).
Need any help or an example pm/msg me.
