Hi,

I have this error: The name 'InputBox' does not exist in the current context.
By making this methode:

        private void cmuTitle_Click(object sender, EventArgs e)
        {
            string value = "";
            if (InputBox.Show("Set Note's title", "title:", ref value) == DialogResult.OK)
            {
                gpclStNotes.Text = value;
            }
        }

Who can help me?

Peter

Maybe you are missing a "using".
Try to right-click over "InputBox" and see if you can see "Resolve"...

I have looked up on the internet and found this:
using Microsoft.VisualBasic;
But still got the error.

I even did this:

1>Right click on project in Solution Explorer and Click on Add Reference

2>Select Microsoft.VisualBasic

3>Click Ok

4. using Microsoft.VisualBasic

InputBox is visual basic code.  There isn't an equivalent in C# as far as I know.  :-(

You have to make your own custom form.

Are you following the instructions there exactly?  (They are in C# and not Visual Basic I hope).

The code you found is NOT using the VB.Net InputBox()...it must be a custom replacement.

The VB.Net InputBox() function:
http://msdn.microsoft.com/en-us/library/6z0ak68w(VS.90).aspx

...is just a wrapper for the legacy VB6 InputBox() function:
http://msdn.microsoft.com/en-us/library/aa445028(VS.60).aspx

Neither returns a DialogResult.  Instead, it returns the value entered into the box.  Hitting Cancel or the 'X' returns a blank string, and you can't differentiate whether the user cancelled the dialog or hit OK with no input.

InputBox() is part of Microsoft.VisualBasic, but is actually located in Microsoft.VisualBasic.Interaction.

Project --> Add Reference --> Microsoft.VisualBasic.
Add "using Microsoft.VisualBasic;".
Now qualify it with "Interaction".

Here's a simple example:



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

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string name = Interaction.InputBox("Name: ", "Please enter your name...");
            label1.Text = name;
        }

    }
}
