How to find loaded forms

[Merchand]

In Dot Net how do you find what winforms are loaded in one running applicaiton? I know you can do this with an API, but is there a way to do it natively in .net?

Also, is there a way to find out what applications are running on a system? (hence, in the the task manager) And is there a way to find out if your application is running in the task mananger. Trying to learn how to do old stuff in a new language (VB.net & C#).

Any help is greatly appreciated!

No API solutions please unless that is the only way.

for the first question ... you will find all running forms with ActiveMdiChild and ActiveForm using respectively depends is your app MDI or not.
For the 2nd question ... you can use Process class and its getProcess method/s

Kulrom, thanks again!

I will R&D the process class and ActiveForm property.

Can I tell what forms are loaded for an application based on the ActiveForm?

Thanks!

ActiveForm/ActiveMDIChild will only the active one in your application.

Form.MDIChildren returns all mdi children forms that are loaded.

In a non-MDI application you can use the OwnedForms property to do the same if you also did set the Owner/AddOwnedForm before.

John you are absolutely right .. sorry merchand for missleading you

THis is how you can find which forms are opened/active

[SIZE=2][COLOR=#008000]' Determine the active child form.
[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] activeChild [/SIZE][SIZE=2][COLOR=#0000ff]As[/COLOR][/SIZE][SIZE=2] Form = [/SIZE][SIZE=2][COLOR=#0000ff]Me[/COLOR][/SIZE][SIZE=2].ActiveMdiChild
[/SIZE][SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] mylist [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]New[/COLOR][/SIZE][SIZE=2] ArrayList
[/SIZE][SIZE=2][COLOR=#0000ff]For [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Each[/COLOR][/SIZE][SIZE=2] activeChild [/SIZE][SIZE=2][COLOR=#0000ff]In [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Me[/COLOR][/SIZE][SIZE=2].MdiChildren
[/SIZE][SIZE=2][COLOR=#0000ff]If [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Not[/COLOR][/SIZE][SIZE=2] activeChild [/SIZE][SIZE=2][COLOR=#0000ff]Is [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Nothing[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Then
[/COLOR][/SIZE][SIZE=2]mylist.Add(activeChild.Text)
[/SIZE][SIZE=2][COLOR=#0000ff]End [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]If
[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Next[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff] 
[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]For[/COLOR][/SIZE][SIZE=2] i [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Integer[/COLOR][/SIZE][SIZE=2] = 0 [/SIZE][SIZE=2][COLOR=#0000ff]To[/COLOR][/SIZE][SIZE=2] mylist.Count - 1
  Messagebox.Show(mylist.Item(i))
[/SIZE][SIZE=2][COLOR=#0000ff]Next[/COLOR][/SIZE]

note: below is an attached project where you can see all that in deeds

Thanks Kulrom and JohnH for the feedback!

And thanks for the ideas and code samples...

* Owner/AddOwnedForm
* ActiveForm/ActiveMdiChild

I'll look at the Owner/AddOwnedForm on-line help and look at the ActiveForm too.
