How to close a form that is open in ShowDialog, from another form

[JohnPapa]

In response to a telephone call, I use the following code to open a form at the lower right corner of the screen to display the users who have this telephone number. When a call is received, the telephone system does something very simple, it executes a batch file and passes the telephone number as a parameter and the batch file creates a file, whose contents are this telephone number. To simplify matters, when a call is made, I can receive a string with the telephone number of the caller and I can pass the telephone number to a form (frmCallerIn) which looks up this telephone number and displays all the users that have this telephone number.

I use the following code to position the form on the lower bottom right of the screen.

Me.Location = New Point(scr.WorkingArea.Right - Me.Width, scr.WorkingArea.Bottom - Me.Height)

I can open the form with
Dim frm2 = New frmCallerIn(sbuf)
frm2.ShowDialog()

I created a Timer programmatically to close the form after say 10 seconds and the Timer is disabled if I click on the form.
When the Timer is disabled, the form will remain on the screen until I exit from the form, even if a new call comes in.

Is there a way to be able to close the form, once a new call comes in. Would opening the form in a separate thread help?

you cannot shut a dialog from another form BECAUSE its in dialog.
Just close it from the dialog.

Perhaps consider just opening the form as Modal, instead of Dialog.
