    Displaying help in a control

    Dear all,

    I have an application written in C#. The main form contains two areas:
    the first one for data input and results, the second one for
    informations. In this last area I would like to display the related help
    (contained in a CHM file) each time a control (in the first area) get
    the focus.

    How can I do that? Which type of control must I use?

    Thanks in advance,

    Philippe

      Hi Philippe,

      the most simple thing I can think of:

      1. Place a short description text resp. CHM help URL in the 'Tag' property
      of every data entry control.
      2. Attach the MouseHover event of each data entry control to a single(!)
      event handler that takes the sender's tag info to open/display the correct
      help text.
      3. Et voilá! :-)


      Greetings,
      Hans

          Oops, what i forgot:

          4. The WebBrowser control is able to display CHM content, just get the weird
          deep linking URL "mk:@MSIStore:. .." from the CHM itself (right click on
          desired page and look at 'Property')

              Hi,

              You can use the mouse over event to detect the mouse movement. or even
              better, mouse enter/leave You need to know the ID (or url) of the
              control.
              You could have one method to handle all the requests, no need to have
              one per control
