Save file dialog box

I want to save a excel file dynamically to a desired location using vb.net savedialog box control.

What I need, is to get the new created file path (i.e Same as save as dialog in windows) .

I'll Use the Open file() elsewhere. When I Use the below code, it says no file present.

FYI..

SaveFileDialog_admin.Filter = "Excel|*.Xls"

SaveFileDialog_admin.Title = "Save An Excel File"

SaveFileDialog_admin.ShowDialog()

Dim file_name = SaveFileDialog_admin.FileName

Label1.Text = Convert.ToString(file_name)

I just want to know how can I get the Newly created File Path And the file name for later use.

Any Suggestion or answer is welcomed.

Thanks in advance.

ASAP
