                    I have a WPF application and I am thinking of creating a help documentation for it. If anyone needs help on some screen and press F1, I don’t like to open a traditional CHM or HTML based screen for that. So my plan is that the screen will describe its own help description and controls will give their introduction and also show you the activity flow to make the user understand about the basic flow of the screen. But what if the user also wants an introduction to each control click while working on a screen? OK, then I will also print the basic introduction into the below status bar on the mouse click of the control (if it has any). It is just a quick guideline to get rid of reading long and boring documentation and give you a very basic information of a screen.
                    Still not clear to you?!! No problem. Let us take a simple screen to understand my thinking here:

            A simple Login screen which controls:

    Textbox for user name
    Password box
    Login button
    And a button to open a Wish-List child scre

                    <Bold>Concept</Bold>
                </Paragraph>
                <Paragraph>
                    To do this I have prepared XML documentation, where I have kept all the necessary descriptions of a control like Title, Help Description, URL for an online guide, shortcut key/hot key, and flow index (if any) for ordering the activity flow sequences. You do need to synchronize the XML yourself if you have changes to any workflow or short-cut/hot keys, which is true for other documentation also. It of course is not a replacement for a  documentation guide, just a quick guideline for the user. That is why I have kept an URL here to go to the on-line guide for more details.
