Before you begin:
User-defined items can be added to the Control Menu of any VFP form. In VFP9 it is also possible to link such menu items to a method of the form.

This code sample is a result of fast and productive discussion on UT. Many thanks to Carlos Alloatti.



Note: VFP9 SP1 is required. I have found that on older VFP9 versions (e.g. 09.00.000.2412) the Close menu item may not close the form had the Control Menu been modified.

    My comment:
    The InsertMenu function has been superseded by the InsertMenuItem function. You can still use InsertMenu, however, if you do not need any of the extended features of InsertMenuItem (e.g. inserting popups).

    Using very similar means, Control Menu items can be modified, disabled or removed.

    Burkhard Stiller noticed that the user-defined control menu items disappeared upon the form's BorderStyle property changed during runtime.

    The are nice examples, except I can't figure out how to get the menu items to do anything. In other words, how do I get "Option 1" to open another form, or run a .prg?

    Thanks,

    Inside the code, PROCEDURE OnMenuItemClicked clearly shows how to do that. Note that this is only available in VFP9 due to its improved BINDEVENT() function.

    VFP8 displays UDF menu items but is not capable to link them to UDF procedures or methods without using external libraries.

    Oi vey, sorry for the previous complaint. I didn't know this was a subscription site. I'll sniff the answer out elsewhere.

    Great site, otherwise. It helped get me a quarter of the way finished with my project.

    I'll try and convince my manager to get us an account.

    Well done,

    But in your example, if we replace oForm.Visible=.T.
    with oForm.Show(1), the user-defined control menu items disappeared.

    Question : Why that code does not work with modals forms ?
