B4J Question Is form already displayed?

[cstangor]

I end up opening the same form twice with frm.show.

I'd like to know if it's already open so I don't.

Thanks in advance.

If I understand your question.

You could open the task manager and look for javaw.exe and how many times it's listed. if you opened it twice it would be there twice.

Thanks for the idea, but I need to do it programatically.

Create a single instance of this form and you will never have two forms displayed.

Actually with this method there is no way of knowing if this is that same program opened or another one. If you want to make sure you only run one instance of the program, you should compile your jar with Launch4J and check the "Allow only a single instance of the application" checkbox in the "single instance" tab.

It seems that it is actually not possible to show the MainForm.Show twice or more. Now if you actually built a class that displays another child form, then in your class you should contain a boolean variable that contains the "show" state of your window, a bit like this:

Sub Class_Globals
    Private frm As Form
    Private isShown As Boolean = False
End Sub

Public Sub Show
    If Not(isShown) Then
        frm.Show
        isShown = True
    End If
End Sub

[edit] By the way, check my signature for "jAutoItX", there is a processList function that returns a list of the current processes.
