Loading an Excel file saved in VB

[Stan]

The following is how I'm opening an Excel file in Form_Load when VB first starts:

    Set xlApp = New Excel.Application
    Set xlBook = xlApp.Workbooks.Open(App.Path & "\test.xls")
    Set xlSheetData = xlBook.Worksheets("input")

The VB program changes the cell values in test.xls. If the user wants to save the changes, I have a menu option:

Private Sub mnuSave_Click()
    Dim xlFile As String

    On Error Resume Next
    
    comDialog.Filter = "Excel File (*.xls)  |  *.xls" 
    comDialog.FileName = "*.xls"
   
    xlFile = comDialog.FileName
    xlBook.SaveAs xlFile

End Sub

My primary question is - the next time the user runs the VB application, how can I modify the Form_Load code so that the saved "xlFile" is loaded instead of the default "test.xls"? Also, is it possible to show the Excel file name in the caption property of a Form?

Thanks
