List all opened WorkBooks in the Task Bar - vb.net

Question

I am trying to list all the opened workbooks and their corresponding sheets in the task bar after that I should be able to select one workbook of the list and open it. My first try was to to show Excel process in Task-Manager but it only shows one open workbook without detecting the number of sheets.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim name As Process() = Process.GetProcessesByName("Excel")
For Each names In name
ListView1.Items.Add(names.MainWindowTitle)
If names.MainWindowTitle <> "" Then
ListBox1.Items.Add(names.MainWindowTitle)
End If
Next
End Sub
Next I tried to use this code but also I can only display one opened workbook, I don't know how to loop through them. I don't have problem of changing the whole code if you have any other method cause I am not sure that it's the solution.
Dim oXL As Microsoft.Office.Interop.Excel.Application
oXL = TryCast(System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application"), Microsoft.Office.Interop.Excel.Application)
oXL.WindowState = Microsoft.Office.Interop.Excel.XlWindowState.xlMinimized
Dim y As String
y = oXL.ActiveWorkbook.Name
ListBox1.Items.Add(y)

Answer 1

Dim objExcel As Excel.Application = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application")
Dim objWorkBook As Excel.Workbook = Nothing
Dim totalWorkBooks As Integer = objExcel.Workbooks.Count
For i As Integer = 1 To totalWorkBooks
objWorkBook = objExcel.Workbooks(i)
With objWorkBook
FullName = .FullName
OnlyName = .Name
