Listbox, How can I find item starting with example "be" doing keypress?

Hallo!

If I have a listBox with 4 items (Beatles, Bruce Springsteen, Scooter, Eagles) and
press "b" in my listBox, SelectedItem will select the first item on "b".
If I press "be" in my listBox, It will select Eagles and not Beatles like Windows Explorer will do.

How can I press more characters and find the item with these characters?
I want my listBox to work like Windows Explorer does.

Example:
----------------------------

ListBox with follow items:
Beatles
Bruce Springsteen
Eagles
Scooter

Here is my wishes:
"b" = Beatles
"be" = Beatles
"br" = Bruce Springsteen
"e" = Eagles

--------------------------------------

Can somebody help me please?

Thanks

I found my own way to do this!

You must have a ListBox on a form.
Here is my code:

public class Form1 : System.Windows.Forms.Form

{

// Textvariable to save the KeyPress characters.

public string KeyPressSearch = "";

// Timer to do the search in listBox.

private System.Windows.Forms.Timer timKeyPressSearch;

public Form1()

{

// Required for Windows Form Designer support

InitializeComponent();

}

private void InitializeComponent()

{

this.timKeyPressSearch = new System.Windows.Forms.Timer();

// timKeyPressSearch

this.timKeyPressSearch.Enabled = false;

this.timKeyPressSearch.Interval = 1000;

this.timKeyPressSearch.Tick +=new EventHandler(timKeyPressSearch_Tick);

}

private void listBox1_KeyPress(object sender, KeyPressEventArgs e)

{

timKeyPressSearch.Enabled = true;

e.Handled = true;

KeyPressSearch = KeyPressSearch + e.KeyChar.ToString();

}

private void timKeyPressSearch_Tick(object sender, EventArgs e)

{

int index = listBox1.FindString(KeyPressSearch);

KeyPressSearch = "";

int oldIndex = listBox1.SelectedIndex;

if (index != -1)

{

listBox1.SetSelected(index,true);

timKeyPressSearch.Enabled = false;

}

else

{

listBox1.SetSelected(oldIndex,true);

timKeyPressSearch.Enabled = false;

}
