I have a weird problem. If I just start a new windows application project, add a keypress event to the form so it looks like this:

CODE
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
        MessageBox.Show(e.KeyChar.ToString(), "Your input");
}


and it works. But if I try to do the same with one of my projects nothing happens when a key is pressed. Could something else be interfering with the event? I'm not using any other event handlers.

in the other forms where this is not working are you wiring the event? Like so..

CODE
Form1.KeyPress +=new KeyPressEventHandler(Form1_KeyPress);


Change Form1 to whatever the other form names are.

Yes, it adds that automatically when you select the form in form designer and double click on the keypress event. That's why the whole thing is so puzzling. I do the exact same thing in my project as I do if I try to start from scratch in a new project.

Seems this is a focus problem. If I delete all the buttons and text boxes it works.

You need to set the KeyPreview Property of your Form to True so it will recognize the key press event.

Yay now it works! Thank you!

I managed to read a 3D object file, draw it, rotate it...but using keyboard was beyond me haha.

I hear ya, hate when seemingly easy tasks stump me but the complicated ones seem easy to figure out.

Glad it's working for you.
