Reading from Keyboard

Hi

I need to get every keys pressed at one time, without needing a
triggered event.

Control.ModifierKeys works perfectly for shift, ctrl and alt, but how
can I check other keys like the letters and arrows?

I quickly checked VB2005, and found out the control class doesn't have
anything either...


Any hint at something that would similarly work like
Control.ModifierKeys would greatly be appreciated.
Also, if the method would detect combinations like UpArrow+LeftArrow
(combinations without modifier keys), that would be even better.

Thanks

Pop this code into you app and see what happens. Set the KeyPreview
property of the form to True to trap the keypress events.

Not sure if this is what you want.
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress

TextBox1.Text = e.KeyChar

End Sub

..NET 1.1 doesn't provide a managed way to determine if a key is pressed or
not except for modifier keys ('Control.ModifierKeys'). 'GetAsyncKeyState'
can be used to determine if a key is pressed:

\\\
Imports System.Windows.Forms
..
..
..
Private Declare Auto Function GetAsyncKeyState Lib "user32.dll" ( _
ByVal nVirtKey As Keys _
) As Boolean
///

Usage:

\\\
If GetAsyncKeyState(Keys.A) Then
...
End If
///

It worked exactly as I hoped! Thank you very much!
