What do you mean by maximum width/height of the screen?

The actual width/height of the working area (thus desktop minus taskbar)?
=> you need to use some Windows API to get it (SystemParametersInfo API with the constant SPI_GETWORKAREA)

The actual width/height of the desktop screen?
=> Screen.Width, Screen.Height

The actual width/height of a window/form?
=> Form1.Width, Form.Height

If you are searching for properties of objects, you can simply type an object's name, enter the point, and a dropdown list will be shown with all available properties... scroll that list and look at the names...

Also, check out the properties window of controls. They very clearly show each property of a control.
