What is a penal?
If you mean a Panel on a Form (a form cannot be on a panel) then try Panel1.Parent.Name

i have a MDI form with MDI child forms. i was trying to add chart in the MDI form. but when MDI child form is open the chart is come to forword and the open child form gose to back. by using penal i have solved the problem but cannot find the active form forom the penal.

Try to be more precise when describing your problem.
Chart and Panel are controls that go onto a Form. A child Form cannot "go to the back" of a Chart or a Panel, only another Form.
How many forms do you have open? The MDI Parent Form plus one MDI Child Form? Or more than one MDI Child Form?
What event on the Panel are you trying to use to find the "Active" form?
By "Active" do you mean the form that currently has Focus?

yes. im trying get currently focus form from the penal. just like get currently focus MDI child form.
for MDI i use this code to get currently focus form.

'This is the code in MDI form Save Button
Dim active_form_name As Object = Me.ActiveMdiChild
active_form_name.CurrentFocusformSaveFunction() 'CurrentFocusformSaveFunction is the child form save function.

purpose is:
in my project each form have a save function and im trying to use MDI form save button to preform active form's save function. now i need to do the same inside the penal.

Assuming you mean "Panel" - what event do you think you could use?
Where is this Panel?
How is the Panel relevant?
You are not making your problem any clearer

This makes no sense, why are you trying to add Form1 to a panel on itself?

Sorry, but that does not help any more than your original question. We have no idea what your code is doing.

You cannot directly get an active form inside a panel as the panel would not have loaded at the beginning of the program and will through a Null Exception. Instead you can use the following to gain access of the form inside your panel.

For Each FormName as Form In Panel1.Controls
If FormName.Name = "FrmName" Then
'Do Something
End If
Next

Or you can access any control (not only forms but any other objects) like the following

For Each ControlName as Control In Panel1.Controls
If ControlName.Color = "Black" Then
'Do Something
End If
Next
