Opening a new form

Hello,

I have one application that works okay.  I'm trying to integrate an on screen keyboard into it.  I tested the demo project and as a standlone it works fine.

I've added it into my project and created the following code to view the form:

        private void button1_Click(object sender, EventArgs e)
        {
            frmKeyboard frmKeyboard = new frmKeyboard();
            frmKeyboard.Show();
        }

It compiles but then just crashes when I click on the onscreenkeyboard.  The demo project I'm using can be found here:

http://www.codeproject.com/KB/miscctrl/touchscreenkeyboard.aspx?fid=285587&fr=26#xx0xx

Here is the code behind frmKeyboard.cs

Any suggestions as to what I might be doing wrong - I'm guesing the passing of data between forms is going wrong somewhere?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
 
namespace keyFortress
{
    public partial class frmKeyboard : Form
    {
        public frmKeyboard()
        {
            InitializeComponent();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            keyboardcontrol1.KeyboardType = KeyboardClassLibrary.BoW.Standard;
        }
        private void button2_Click(object sender, EventArgs e)
        {
            keyboardcontrol1.KeyboardType = KeyboardClassLibrary.BoW.Alphabetical;
        }
 
        private void button3_Click(object sender, EventArgs e)
        {
            keyboardcontrol1.KeyboardType = KeyboardClassLibrary.BoW.Kids;
        }
 
        private void keyboardcontrol1_UserKeyPressed(object sender, KeyboardClassLibrary.KeyboardEventArgs e)
        {
            richTextBox1.Focus();
            SendKeys.Send(e.KeyboardKeyPressed);
        }
 
        private void keyboardcontrol1_Load(object sender, EventArgs e)
        {
 
        }
    }
}

Ah that was it, I was missing the first line.

Now the keyboard displays.

At the moment the letters appear within a richtextbox on frmKeyboard.  How can I change this so that letters appear within a control on frmMain?

Thanks.

i'm shure that there is better idea but you can do this:
but ShowDialog means that your main form is waiting for ending frmKeybord..
so make this:
 frmKeyboard frmKeyboard = new frmKeyboard();

as field in your frmMain class..
and in button_click
make only frmKeyboard.Show();

frmKeyboard frmKeyboard = new frmKeyboard();
frmKeyboard.TopMost = false;
frmKeyboard.Parent = yourPanelControl;
frmKeyboard.Show();

frmKeyboard fk = new frmKeyboard();
private void button1_Click(object sender, EventArgs e)
{
    fk.Parent = yourPanel; //Control
    fk.Show();
}
