TextBox KeyPress

Hi,
I was wondering how could I do something which was really easy to do
with VB 6.0.
Let's suppose I have a textbox in which I want to capture some key
events to handle them (for example a numeric only textbox). It is easy,
with e.handled=True.
But what if what I want to do is replacing the key I'm pressing with
some other code? For example, catching all the vowels keys and
replacing with "*", so when they are writing in the textbox, a message
like "I like cats" would show like "* l*k* c*ts". I don't have access
to replace the incoming key, so no idea of doing this...
Thanks!

Well, you can say that e.handled = True and then manually append the * to
the string in the text box yourself.

Hi,

Not sure what you mean by 'I don't have access to replace incoming key'.
This might work for you:-

Private Sub TextBox1_KeyPre ss(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyPressE ventArgs) Handles TextBox1.KeyPre ss
If e.KeyChar = "e" Then 'Add additional Boolean logic for other
vowels
TextBox1.Text = TextBox1.Text & "*"
TextBox1.Select ionStart = TextBox1.Text.L ength
e.Handled = True
End If
End Sub

Hello, I am trying to edit a textbox which contains a number. When focus is on the textbox, and a user press the "arrow up", I would like the textbox value to increase of 100, and at the opposite when the user press "arrow down", I would like this value to decrease by 100. For the moment I have done that using the "keypress" event, but I have a problem, as this event reacts to any key of the keyboard. So I would need whether another idea...

Because of a legacy (originally DOS) Sub Procedure "AlphaInput" that is called in thousands of places in our code, I need to be able to set a variable, "KeyedString",to the value of TextBox.Text (KeyedString originally was set by tracking each individual key pressed, independently of textbox.text) Since we're setting KeyedString during the keypress event, Textbox.Text is always one character behind.

I would like to be able to know if the user has pressed a key in any text box on a winform or in other words, if he is editing a record. I would like to know this as soon as he presses any key. I know that I can check for keypress on a given field, but I don't want to do this for every field on the form. Is there a way to determine what I want to know?
