How do you open Excel 2007 and get the Menu items to show up

 Hi All,
 
I can open a work book, but it is just the workbook, what is the secret to show the menu items?
 
Here is what I have currently

private void Form1_Load(object sender, EventArgs e)
{
filePath = @"FileName.xlsx";
App = new Excel.ApplicationClass(); // Creates a new Excel Application

App.WindowState = Excel.XlWindowState.xlMinimized;
App.ShowStartupDialog = true;
App.ShowSelectionFloaties = true;

App.ShowWindowsInTaskbar = true;

workbook = (Excel.Workbook)(App.Workbooks.Open(filePath, 0, false, 5, "", "", true,
Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, false, false));
}
