Greetings gentleman;

I was checking out the example that you indicated me and honestly, I should tell to you that it is much simpler of what I thought; in fact I did my own example.

Now; I have the following restlessness and I would like to know if I can have your accustomed help; the questions are:
1.- How making so, when the user makes click on the button and the process begins; the system disappears of the screen (visible = .f.) and it is activated in the taskbar or systray the icon of the application indicating the user that the application is running.
2.- After the process concludes; what I have to make to making disabled in the taskbar the icon and it is shown the form again in the screen; indicating it to the user that the process has concluded satisfactorily.

What idea could you give me?
¿How do you consider that is possible to carry out this task?

TIA
Andrews
