I would like to ask someone, even someone has told me it is not possible.
I have a child form2 which is always visible (there is a listView, which shows some data). Then I have a new child form 3 (which is currently opened) and the form3 now does come code (gets some data from the hdd). And when the process is finished I would like to refresh the listView in the form2 (I would like to call a method which refreshes the listView). I was trying that, and the code went over that method, but nothing has happened.
That guy that I was talking aobut on the beginning has told me that it is not possible, because I didn`t call form2.Show(); metod. I can show it, but this is not something that I want to do atm.
So I would like to know, if it`s possible to execute the method for refreshing on the form2, from form3, even if the form2 is not shown? (but the form2 is always visible on form1 - its just not physicly visible if some other form is over it).
