Automating Excel


I need to automate Excel from VB.Net. What I need to do, is get data from a DtaBase such access, and populate that data into an excel file. The excel file has to be a template, so it already exists at a certain location on the machine. I am able to retrieve the data and I can populate to excel, but when it is finished, the file is not saved. What I want to do, is populate the template excel, then save it as a different excel file, allowing the user to choose the location and name of the new file. Below is the code I am using to populate excel.
Dim xcApp As New Microsoft.Office.Interop.Excel.Application
        Dim xcWB As Microsoft.Office.Interop.Excel.Workbook = xcApp.Workbooks.Open("C:\Documents and Settings\117152\My Documents\Visual Studio 2008\Projects\ECA\ECA\Documents\Simple.xlt")
        Dim xcWS As Microsoft.Office.Interop.Excel.Worksheet = xcWB.Worksheets("sheet1")
        Dim xcRange As Microsoft.Office.Interop.Excel.Range
Dim ADOConnection As ADODB.Connection
        Dim RS As ADODB.Recordset
        ADOConnection = New ADODB.Connection()
        RS = New ADODB.Recordset()
        ADOConnection.ConnectionString = myConnection
        RS.Open(SQLStr1, ADOConnection)
        While Not RS.EOF
            xcRange = xcWS.Range("A4")
            xcRange.Value = RS.Fields("transMnth").Value & " " & RS.Fields("transYear").Value
            xcRange = xcWS.Range("A5")
            xcRange.Value = RS.Fields("transIncome").Value
        End While
'clean up
        xcApp = Nothing
        xcWB = Nothing
        xcWS = Nothing
        xcRange = Nothing

Ok, I have found out that it is savibng the file to the My Documents folder, so what I need now is to know how to save it to a user selected forlder... and also I would like to automatically print it to the default printer while it is being saved. If a printer exists of course, if a printer does not exist then save the file and give the user a message thatthere is no printer.
This is how I would do it in Excel - I can't test it on VB.Net, but I suggest that you intergrate the first sub in place of


You will need to provide a new filename, under the fname variable



Sub SavePrint()
    Dim myDir As String, fname As String
    myDir = BrowseForFolder
    fname = "yourfile"
    If myDir <> vbNullString Then
        xcWB.SaveAs myDir & "\" & fname
        MsgBox "user did not save file"
    End If
End Sub
Function BrowseForFolder(Optional OpenAt As Variant) As Variant
'Function purpose:  To Browser for a user selected folder.
'If the "OpenAt" path is provided, open the browser at that directory
'NOTE:  If invalid, it will open at the Desktop level
    Dim ShellApp As Object
    'Create a file browser window at the default folder
    Set ShellApp = CreateObject("Shell.Application"). _
                   BrowseForFolder(0, "Please choose a folder", 0, OpenAt)
    'Set the folder to that selected.  (On error in case cancelled)
    On Error Resume Next
    BrowseForFolder = ShellApp.self.Path
    On Error GoTo 0
    'Destroy the Shell Application
    Set ShellApp = Nothing
    'Check for invalid or non-entries and send to the Invalid error
    'handler if found
    'Valid selections can begin L: (where L is a letter) or
    '\\ (as in \\servername\sharename.  All others are invalid
    Select Case Mid(BrowseForFolder, 2, 1)
    Case Is = ":"
        If Left(BrowseForFolder, 1) = ":" Then GoTo Invalid
    Case Is = "\"
        If Not Left(BrowseForFolder, 1) = "\" Then GoTo Invalid
    Case Else
        GoTo Invalid
    End Select
    Exit Function
    'If it was determined that the selection was invalid, set to False
    BrowseForFolder = False
End Function

Instead of opening the template, create a new workbook, using the template....

     Dim xcWB As Microsoft.Office.Interop.Excel.Workbook = xcApp.Workbooks.Add("C:\Documents and Settings\117152\My Documents\Visual Studio 2008\Projects\ECA\ECA\Documents\Simple.xlt")

...and save the file using something like this....

    Dim sfd As New SaveFileDialog
    sfd.Filter = "Excel Files (*.xls)|*.xls"
    sfd.FileName = "Filename.xls"
    If sfd.ShowDialog = System.Windows.Forms.DialogResult.OK Then
    End If

Moving the Close statement to this snippet of code enables you to close the workbook without saving if the user clicks cancel on the dialog.
