Error reading Excel using VB.NET - vb.net

i have this code to read Excel file
Dim scheduleFileName As String
'Creating Excel Object
Dim fileName As String
fileName = "E:\Vb Deployment\scheduling\scheduleSheet.xlsx"
Dim objExcel As New Excel._ExcelApplication
Dim objWrkBk As Excel.Workbook
Dim objSht As Excel.Worksheet
Dim testdata As String
objWrkBk = GetObject(fileName)
' or objWrkBk = objExcel.Workbooks.Open("C:\test.xls")
objSht = objWrkBk.Worksheets(0)
testdata = objSht.Cells(1, 1).Value.ToString()
But it give at error on line
objSht = objWrkBk.Worksheets(0)
Error: member not found....
Could you please let me know why I am getting this error and how I could correct it?

Workbook does have a member Worksheets. The only thing that's missing is the typecast
objSht = CType(objWrkBk.Worksheets(0), Excel.Worksheet)

Excel.Worksheet.Columns(1).NumberFormat = "#" Late Binding Warning

I'm getting a late binding warning on the below code, specifically the last line.
Dim xlApp As New Excel.Application
Dim xlWorkbook As Excel.Workbook = xlApp.Workbooks.Add()
Dim xlSheet As Excel.Worksheet = CType(xlWorkbook .Sheets(1), Excel.Worksheet)
xlSheet.Name = "Summary"
xlSheet.Columns(5).NumberFormat = "#"
I'm not getting the error on the .Name property line so presumably it's an issue with .Columns?
Why is this?
Try removing the New keyword in
Dim xlApp as New Excel.Application

Method or data member not found error for Range.Address method

I'm very new to VBA, but I am trying to make a program that will offer suggestions for translations when selecting and right-clicking a word in MS Word. I am getting the message "Compile-Error: Method or data member not found" in the code below at Found.Address:
Dim Current As String
Dim oSheet As Range
Dim Found As Range
Dim firstAddress As String
Dim oChanges As Worksheet
Dim sFname As String
Dim oExcel As Excel.Application
Set oExcel = New Excel.Application
oExcel.Visible = False
sFname = "C:\Users\user\Desktop\translations.xlsx"
Set oChanges = oExcel.Workbooks.Open(FileName:=sFname)
Set oSheet = ActiveSheet.UsedRange
'Prepping Excel File
Set oSheet = ActiveSheet.UsedRange
Current = Selection.Text
With oSheet
Set Found = .Find(Current)
If Not Found Is Nothing Then
firstAddress = Found.Address

I copied this format directly from the Range.Find help page for VBA. What am I missing?

VBA Type mismatch error when setting Excel Range in Word

I have the following code as part of my sub trying to assign a range:
'Set xlApp = CreateObject("Excel.Application")
Dim xlApp As Object
Set xlApp = GetObject(, "Excel.Application")
xlApp.Visible = False
xlApp.ScreenUpdating = False
Dim CRsFile As String
Dim CRsMaxRow As Integer
' get the CR list
CRsFile = "CRs.xls"
Set CRsWB = xlApp.Workbooks.Open("C:\Docs\" + CRsFile)
With CRsWB.Worksheets("Sheet1")
.Activate
CRsMaxRow = .Range("A1").CurrentRegion.Rows.Count
Set CRs = .Range("A2:M" & CRsMaxRow)
End With
Dim interestingFiles As Range
' get the files names that we consider interesting to track
Set FilesWB = xlApp.Workbooks.Open("files.xlsx")
With FilesWB.Worksheets("files")
.Activate
Set interestingFiles = .Range("A2:E5")
End With
Do you have any idea why am I getting a run time type mismatch error?
If you run the code from Word then the problem is in the declaration of 'interestingFiles' variable. Range exist in Word as well so use either Variant or add reference to Excel and then use Excel.Range.
Without Excel reference:
Dim interestingFiles As Variant
And with Excel reference:
Dim interestingFiles As Excel.Range
Kindly set xlApp object as in below code.
Also you provide complete path for your workbook when opening it.
Sub test()
Dim interestingFiles As Range
Dim xlApp As Object
Set xlApp = GetObject(, "Excel.Application")
' get the files names
Dim path As String
path = "C:\Users\Santosh\Desktop\file1.xlsx"
Set FilesWB = xlApp.Workbooks.Open(path)
With FilesWB.Worksheets(1)
.Activate
Set interestingFiles = .Range("A2:E5")
End With
End Sub

How to manipulate an excel workbook with Excel.Workbook

So, I can't find any methods with file opening in Excel.Workbook or Excel.Application, and I am wondering why.
I have path to an Excel file, and I would like to manipulate it. I understand I have to use Excel.Application, Excel.Workbook, and Excel.Worksheet. The file to the Excel file is ExcelFilePath, what should I do to make it possible?
You first need to add the reference to Microsoft.Office.Interop.Excel to your project in order to use the Excel API, then fill the variables:
Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWS As Excel.Worksheet
xlApp = New Excel.ApplicationClass
xlWorkBook = xlApp.Workbooks.Open(sFilePath)
xlWS = CType(xlWorkBook.Worksheets(sheetNameOrIndex), Excel.Worksheet)
And then you only need to use the methods they have. For example:
Dim sVar as String = xlWS.Range("C5").Value.ToString()
Try this: from my project
Dim xapp As New Microsoft.Office.Interop.Excel.Application
Dim wb As Workbook = xapp.Workbooks.Add
Dim ws As Worksheet = wb.Worksheets(1)
ws.Activate()
'Fill header of the sheet----------------------------------
For i As Integer = 1 To dgvcustomer.Columns.Count
ws.Cells(1, i) = dgvcustomer.Columns(i - 1).HeaderText
Next
'End header------------------------------------------------
Dim Dgrow, Dgcell, Dgcol As Integer
Dgrow = 1
Dgcell = 1
'Fill Sheet ------------------------------------------------------------------------------------------------
While (Dgrow <= dgvcustomer.Rows.Count)
Dgcol = 1
While (Dgcol <= ws.UsedRange.Columns().Count)
ws.Cells(Dgrow + 1, Dgcol).value = dgvcustomer.Rows(Dgrow - 1).Cells(ws.Cells(1, Dgcol).value).Value
Dgcol += 1
End While
Dgrow += 1
End While
'End fill sheet---------------------------------------------------------------------------------------------
wb.SaveAs(dlgSaveFile.FileName)
wb.Close()
xapp.Quit()

Getting TXT file to Excel

I have the following code to get a text file to an Excel workbook.
Dim XlApp As Excel.Application = New Excel.Application
Dim XlWbk As Excel.Workbook = XlApp.Workbooks.Add
Dim SheetName As String = "Sheet1"
Dim XlWkst As Excel.Worksheet = FindSheet(XlWbk, SheetName)
Dim XlRng As Excel.Range = Nothing
If XlWkst Is Nothing Then
XlWkst = DirectCast(XlWbk.Sheets.Add(After:=XlWbk.Sheets(XlWbk.Sheets.Count), _
Count:=1, Type:=Excel.XlSheetType.xlWorksheet), Excel.Worksheet)
End If
Dim Lines() As String = File.ReadAllLines("C:\TEMP\FlowgateNNL_Mar2011_base.txt")
Dim RC(Lines.Length - 1)() As String
For I As Integer = 0 To Lines.Length - 1
RC(I) = Lines(I).Split(CChar(vbTab))
Next
XlRng = XlWkst.Range("a1")
XlRng.Value = RC
XlApp.Visible = True
This method seems to be the fastest way to read and parse a CSV file for dumping to Excel on my computer. it is choking on XlRng.Value = RC. Excel doesn't seem to like RC.
Any ideas for getting Excel to accept the data?
You are setting the value of a cell to an array that contains an entire CSV? I'm guessing this throws a type error.
This is probably more along the lines of what you want.
Dim XlApp As Excel.Application = New Excel.Application
Dim XlWbk As Excel.Workbook = XlApp.Workbooks.Add
Dim SheetName As String = "Sheet1"
Dim XlWkst As Excel.Worksheet = FindSheet(XlWbk, SheetName)
Dim XlRng As Excel.Range = Nothing
If XlWkst Is Nothing Then
XlWkst = DirectCast(XlWbk.Sheets.Add(After:=XlWbk.Sheets(XlWbk.Sheets.Count), _
Count:=1, Type:=Excel.XlSheetType.xlWorksheet), Excel.Worksheet)
End If
Dim Lines() As String = File.ReadAllLines("C:\TEMP\FlowgateNNL_Mar2011_base.txt")
For I As Integer = 0 To Lines.Length - 1
XlRng = XlWkst.Range("a1").Offset(I, 0)
Dim RC() As String = Lines(I).Split(CChar(vbTab))
For J As Integer = 0 To RC.Length - 1
XlRng = XlRng.Offset(0, J)
XlRng.Value = RC(J)
Next
Next
XlApp.Visible = True
Did you try simply opening the CSV file directly as in:
Dim XlApp As Excel.Application = New Excel.Application
Dim XlWbk As Excel.Workbook = XlApp.Workbooks.Open("C:\TEMP\FlowgateNNL_Mar2011_base.txt")
XlApp.Visible = True
If you have a valid CSV file do yourself a favor and use a specialised CSV datareader which can handle all the weird problems of CSVs (quotes etc.)
Personally, I like http://kbcsv.codeplex.com/ very much - it is simple to use and fast.
Then just dump the interop part and use the EPPLUS Library to write the data to an excel file - it is magnitudes faster and mind boggingly simple.
Your workflow would look like this:
Use KBCSV to load the data to a datatable.
Use EPPLUS's method "LoadFromDataTable" to generate a new excel file and save it.
Done!
