Automating Excel

Hi,

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
        ADOConnection.Open()
 
        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
            RS.MoveNext()
        End While
 
        RS.Close()
 
 xcWB.Save()
 
'clean up
        xcWB.Close()
        xcApp.Quit()
        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.

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
xcWB.SaveAs(sfd.FileName)
xcWB.Close()
Else
xcWB.Close(False)
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.
