I want to create a fullscreen window in which I can draw in.
I dont want any window frame to be visible, or the windows toolbar to be visible. I tried doing this with a regular winform,
and changing the dimensions to the screen dimensions, but
the window frame and toolbar were still visible. How should
I go about entering into some kind of fullscreen mode in
which I can draw in

However if you set the form's FormBorderStyle to FormBorderStyle.None then that'll get rid of the title bar. If you then do this:
DesktopBounds = Screen.GetBounds(this);
inside your form's OnLoad method then it'll resize the form to cover the entire screen.

Creating a window that covers even the task bar is probably not a good idea. I as a user would not run such an app.
I have a situation were doing just that is totally appropiate. I'm developing a HMI (human-machine-interface) application. Basically, the less the users see of the operating system, the less trouble they can cause...
