Trapping the Enter Key

Hello,

Is there a way to trap when the user presses a key on the keyboard (such as the Enter Key)? The value of e.keycode in the Key_Up event is always none.

Thanks

Hello vpalhories!

Yes, absolutely. While you are creating the layout for the keyboard, assign the 'Enter' to MappedKey, not to SpecialKey property. Then handle KeyDown event and in there, you will receive a key code of 17 for Enter. While in Keyboard Designer, you will not find Enter in the combo box offer for MappedKey property. Therefore, you will have to type it there - type 'Enter' - without the quotes.

I see that you can type "Enter" into the MappedKey field, and I have found out that there are other words that can be typed as well, like "Multiply", "Subtract", and others. Is there a complete list of these "user-entered" options that are not in the ComboBox of the MappedKey property?

Hello Vahideh,

we've changed the sample project available on our web page: [beemobile4.net]

We've tested it on WinCE 5.0 with the latest version of BeeMobile.Keyboard.CF20.dll (v.2.0.0.5). The events occured only once. Are key events raised for every keys or just for some secial ones? Do you see the same behaviour on our test project as well?

Please send us the whole sample project.

Thanks in advance!

Hi,

We're able to reproduce the issue.

You need to change the focus to a TextBox control. When the KeyboardControl has the focus it sends itself the pressed keys.

When a Form is activated please set a focus by calling e.g.: textBox1.Focus()

And it will work as expected.
