Retrieving values from existing worksheet
 

I am trying to convert a program that worked well in Visual Basic 6 to the
..net version of Visual Basic. I am attempting to get a value from a cell in
an existing worksheet, but I am unable to do so. I get an error, "Exception
from HRESULT: 0x800A03EC", every way that I have tried. It fails attempting
to set temp2. The code is simple and the answer must be too, but it escapes
me. Here is the code:

Imports Microsoft.Office.Interop.Excel
Imports System.IO
Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim returnFile As String = "C:\MyPool\MyPoolData\Test.xls"
Dim curFile As String = "c:\MyPool\MyPoolData\OBGSchedule.xls"
Dim temp, temp2 As String

Dim xla As New Application

Dim xlb As Workbook

Dim xls As New Worksheet
Dim xlsData As New Worksheet

xlb = xla.Workbooks.Add
xls = CType(xlb.Worksheets.Add, Worksheet)
xlsData = CType(xlb.Worksheets.Add, Worksheet)
'Dim xlr As Range

xls.Activate()
xlsData.Activate()

xlb = xla.Workbooks.Open(curFile)
xls = CType(xlb.Worksheets("Sheet1"), Worksheet)
xlsData = CType(xlb.Worksheets("Data"), Worksheet)

For Each ws As Worksheet In xlb.Worksheets
temp = ws.Name
temp2 = (ws.Range(ws.Cells(6, 2)).Value).ToString
Next

For Each ws As Worksheet In xlb.Sheets
temp = ws.Name
temp2 = (ws.Range(ws.Cells(6, 2)).Value).ToString
Next

'xlb.SaveAs(returnFile, FileFormat:=XlFileFormat.xlWorkbookNormal)
xlb.Close(SaveChanges:=False)
xla.Quit()

End Sub
End Class

Maybe there's something here which might help:

I'm not clear on why you assign "xlb" and "xlData" twice, but don't use the
first assignment ?

assigned to temp 2 is "System.__ComObject" as a string. Code follows:

Retrieving values from existing worksheet
 

Try:

temp2 = ws.Cells(6, 2).Value.ToString

In VBA you can get away by relying on default properties like Value: not
sure if that's also the case in VB.NET

Nope, I tried that, but .value is not included in the intellisense selection
window. It won't compile.

Retrieving values from existing worksheet
 

All of the MS examples I've seen use the .Value property, so it's a bit
strange your code won't even compile with it.
