Hi All,
I am trying to get Form keydown event in compact framework 3.5 but event is not triggering.
I have just one form form1. -
Public Class Form1
-
Dim oBinarySave As New Binary_Serialization
-
Dim FlagFormKeyDown As Boolean = False
-
Dim uicounter1 As UInt16 = 0
-
Dim uicounter2 As UInt16 = 0
-
-
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyDown
-
If Not FlagFormKeyDown Then
-
FlagFormKeyDown = True
-
uicounter1 += 1
-
Label1.Text = uicounter1
-
End If
-
-
End Sub
-
-
Private Sub Form1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Panel1.KeyUp
-
uicounter2 += 1
-
Label2.Text = uicounter2
-
FlagFormKeyDown = False
-
End Sub
-
End Class
-
whts problem...?

Are you sure it's not triggering?
Did you use the debugger to determine if the application steps into the method that handles the KeyDown Event?
It may be that you aren't refreshing the display and so the Label you're using to display the uicounter1 variable isn't updating.

If anything other then the form has the focus, it won't generate key up/down events.
Thanks,
for your guidance. the application is for wince. and i dont have win ce emulator installed on my system thats why i cannot go in debug mode.
Secondly form is selected and all keyboards events goes to form.
I have got solution. The solution is that there is a Key Preview property of forum that is set to false by default. if we turn it to true. then events will trigger and now triggering.

If your device has active sync, you can debug through that.
I always wondered about that property, sometimes it works for people, other times it doesn't.

there,
I'm trying to capture the Function keys (F1-F4, basically) but it's kind of
difficult compare to .NET Framework. I have tried KeyPress, KeyDown, etc,
without success.
I downloaded the P/Invoke sample, kind of hard to digest.
Is there another workaround?
I'm using: Pocket PC2003 (emulator also), VS.NET 2003.(especifically C#).
Any help will be highly appreciated

Hi,
How do i listen for windows messages in c# on
compact.net? I have a window containing an instantiation
of the HTML viewer control, which is a child of the main
form. As the compact implementation of the form class
does not have a wndproc function to override, i cannot
get the messages. I cannot use a message window, as the
window i am listening to will then not display.
Is there another method of doing this?

controls and the form.

Hi world! we are pretty new to JavaScript and have been
struggling for now 2 days on this problem ... We would
appreciate mercy if anyone can give us some.
Basically we are trying to simulate the tab key when the
down arrow key is pressed. (we know there are other way
to control focus flow but we use a lot of dynamic jsp fields,
that will make the flow control a nightmare, we just want
basic tabbing from the arrow key)

The .NET WebBrowser control in the Compact Framework 2.0 is a major
headache.
Once it takes the focus (e.g. by the user tapping on it) it keeps it
and keyboard events are not passed to the form anymore even though
KeyPreview is set to true.
If there are no other controls on the form we don't get them at all to
start with.
I added a tiny textbox with same colors as the form so we can at least

I created a form for PPC 2003 using VB.Net compact Framework
One of my forms is longer than the screen, and the Autoscroll function that is on VB.Net is not supported by the compact framework (shocking.. I know!)

Hey - I am making my first C# form application! (More a teach myself app
than any pratical application)
I have a listbox that always has the control so I made an event handler for
KeyDown.
I seem to be losing information when Casting to char, since I never have any
problem using special keys if I use something like e.KeyCode == Keys.Delete
But . . there is no Keys.Astericks (or Star or similar)
