Considerations When Not Dynamically Resizing
Go Up to Programming for Varying Host Environments
If the forms and visual controls that make up an application are not dynamically resized at run time, design the application's elements for the lowest resolution. Otherwise, the forms of an application run on a computer configured for a lower screen resolution than the development computer may overlap the boundaries of the screen.
For example, if the development computer is set up for a screen resolution of 1024x768 and a form is designed with a width of 700 pixels, not all of that form will be visible within the desktop on a computer configured for a 640x480 screen resolution.
