How to send a char to TextBox

[scottiedog]

Hi
How can I send a char to Textbox so that KeyPress event is called? I have a button and with a click I would like to send a char, e.g. "C", to the Textbox. But Textbox1_KeyPress is not catching the event (I can step thru KeyPress ok but nothing goes to TextBox). KeyPress itself works fine with key stroke via keyboard

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Clic
Dim e2 As New System.Windows.Forms.KeyPressEventArgs(CType("C", Char)
TextBox1_KeyPress(TextBox1, e2
End Su

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPres
If Not Char.IsLetter(e.KeyChar) And Not Char.IsControl(e.KeyChar) The
e.Handled = True ' ignor
End I
End Su

TIA.

To clarify. KeyPress is called just that no text goes to textbox via button click.

Maybe by using 'SendKeys.Send' -- nevertheless, why do you want to do
that?!

I'm creating a calculator type application. Plain SendKeys won't work. Or perhaps I don't know how to use SendKeys. Any suggestions?

use texbox1_change or somthing around that.

Ummm... I'll offer the suggestion that you are going about this "backwards"
(tm)

Rather than designing "intelligent systems" in the UI you might try build a
Calculator Class, then databind to the textbox. As you enter data the
Calculator object will validate not a keypress or some other UI event. That
way if the calculator "totals" and the accumulator property is changed in
the Calculator object it will automatically (through binding) be shown in
the textbox also.

I don't know what you mean by text change.
My problem is that I can call keypress event successfully but nothing happens to textbox. No entry to the textbox. Think of what I'm trying to do as a calculator app but I have to do some validation so I must go through KeyPress event whether it is via keyboard or button click event (sending char to textbox).

Actually, SendKey worked. I had to give focus to the textbox first. Thanks
About the class, it is interesting approach. This means that I won't need textbox after all
I would just print out the result to, say label as I capture the key stroke (or button click), calculate, and then to label
Not bad at all

Thanks guys.
