Z-transform, like the Laplace transform, is an indispensable mathematical tool for the design, analysis and monitoring of systems. The z-transform is the discrete-time counter-part of the Laplace transform and a generalization of the Fourier transform of a sampled signal. Like Laplace transform the z- transform allows insight into the transient behavior, the steady state behavior, and the stability of discrete-time systems. A working knowledge of the z-transform is essential to the study of digital filters and systems.

I have often found that user input edit boxes on a dialog require much more than the capabilities provided by the basic CEdit control. A common problem I have encountered is the need for an edit control that restricts the characters that can be entered into the box in some manner. Some types of restrictions would include confining input to a specific set if legal characters, excluding characters in an illegal set, limiting text to a maximum length and providing for fixed length strings that may be padded to the right with spaces if they are too short.
