vb.net webform on 2000 returns "Bad variable type" for Excel

David Reynolds

Hi Everybody,

I have a vb.net webform where I create the Excel
application/workbook/worksheet. On Windows 2000 server for some reason, I
keep getting an error("Bad variable type") when trying to first set the value
to a cell. I don't have the problem on 2003 server or XP, and I'm wondering
if anyone knows of a get around on 2000?

Try
EApp = CreateObject("E xcel.Applicatio n")
EWB = EApp.Workbooks. Add
ESh = EWB.Worksheets. Add
Add2Log("Creati ng Excel objects")
Catch ex As Exception
Response.Write( "<br><br>Er ror Creating Excel. Message:" &
ex.Message.ToSt ring)
Add2Log("Error: " & ex.Message.ToSt ring)
Exit Sub
End Try

......

ESh.Cells(1, 2).value = "Total"

The error message has been puzzling me and I can't seem to see why it would
return that error. It does seem to be creating the Excel objects okay

I can reproduce it with the followoing aspx file. It works fine for me under
2003, but just hangs in 2000 server.

<script language="VB" runat="server">

Sub Page_Load(Sende r as Object, E as EventArgs)
Dim EApp As Object, EWB As Object, ESh As Object
Dim rowcount
Try
EApp = CreateObject("E xcel.Applicatio n")
EWB = EApp.Workbooks. Add
ESh = EWB.Worksheets. Add
rowcount = 1
ESh.Cells(rowco unt, 2).value = "Total"
lblMsg.Text = Esh.Cells(rowco unt, 2).Value
Catch ex As Exception
Response.Write( "<br><br>Er ror Creating Excel. Message:" &
ex.Message.ToSt ring)
Exit Sub
Finally
EWB.Close()
Esh = Nothing
EWB = Nothing
EApp = Nothing
End Try

End Sub

</script>

David,

I'm having exactly the same problem, only I'm trying to access the content
of a cell. Did you ever come up with a resolution?

Thanks,
Paul
