Function Does .NET NPV() Use? Doesn't Match Manual Calculations?

Jun 17, 2010

I am using the NPV() function in VB.NET to get NPV for a set of cash flows. However, the result of NPV() is not consistent with my results performing the calculation manually (nor the Investopedia NPV calc... which matches my manual results)

My correct manual results and the NPV() results are close, within 5%.. but not the same...

Manually, using the NPV formula:
NPV = C0 + C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^3 + .... + Cn/(1+r)^n

The manual result is stored in RunningTotal

[Code]...

The MSDN page example clearly states that the initial expense should be included in the cash flows list.

Delete Excel Columns And Duplicate Values

Jul 5, 2011

I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.

Code:
Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String)
Dim contents = New List(Of String)
Try
Dim files = Directory.GetFiles(path, "*.xls")
If (files.Length = 0) Then errorMessage = "Please select the files"
For Each file In files
[Code] .....

I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase

Doesn't The Union Function In LINQ Remove Duplicate Entries?

Aug 9, 2009

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:

Sub Main()
Dim firstFile, secondFile As String(), resultingFile As New StringBuilder
firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine)
secondFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "2.txt").Split(vbNewLine)

[2008] Excel Access Excel Conversion

Jan 24, 2009

I'm coming to the conclusion that the things I want to do in a database are better done if I run a conversion code from Excel to Access, do mighty things in Access, then have the option of converting back to Excel to distribute elsewhere. I'm already familiar with using Access and the code I keep finding in threads almost always refers to .mdb files. Below is a conversion that does not seem to work (button2). I'm trying to do this through ADO with OleDb connections. If I can convert to Access much will make sense.

Public Class Form1
Private Adapter As New OleDb.OleDbDataAdapter

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()

Winforms - Writer To Excel Function Working On One Pc But Not On Another

Mar 29, 2011

I have a vb.net function which uses oledb to create a spreadsheet, then treat it like a database, creating tables and inserting values. The function takes in a filename and a dataset, and returns the filename if it worked. The function works beautifully on my dev machine, but not other PCs. Below is my function, is there anything wrong with the code? EDIT: There are no errors being thrown, the resulting file doesn't contain any data.

Excel - Equivalent Of Optional Range Argument In VBA Function

Aug 31, 2009

I have an Excel VBA function that takes a number of optional parameters, including an optional Range:
Function DazBeta(A As Range, Z As Range, _
B As Integer, _
Optional Freq As Integer = 1, _
Optional c As Double = 0, _
Optional r As Range, _
Optional Pct As Boolean = True, _
Optional Label As Integer = 1)

I am translating to VB.NET, and it's the optional Range that is giving me grief because VB.NET does allow optional Ranges. Or rather, optional parameters must provide a default value. What is the recommended way to change the VB.NET function signature so that the code is callable from an Excel cell as a UDF? (The VB.NET implements a UDF, the assembly is registered as a COM server, and the Excel spreadsheet is told of this server and type library, allowing the VB.NET code to be called from an Excel spreadsheet cell.) I have other compilation problems, so I have not been able to explore this. I am thinking that accepting an optional Object (default value Nothing) might work and then I could cast the Object to a Range. Alternatively, if there were a default value that could be specified with an optional Range, that would work, too.

Use The VLookup Function To Look Up A Raw Score And Convert It Using An Excel Worksheet?

Nov 4, 2009

I'm attempting to use the VLookup function to look up a raw score and convert it using an excel worksheet. However, instead of returning the figure in the lookup location, its returning the value that i'm looking up. For example, i'm looking up the number 5, it should give me the value of 63 but instead of returning the value 5.

xcApp = CreateObject("Excel.Application")
Excel1.OpenBook("testbook.xls")
xcWS = CType(xcWB.Worksheets("SOMATIC"), Excel.Worksheet)
MsgBox(xcApp.WorksheetFunction.VLookup(5, xcWS.Range("A2:F12"), 1, False))

EDIT: The above code DOES work, but it does not work with the following code(returns number i'm sending). One thing I did notice, it doesn't seem to be looping through all the Subnames...I just get one result and there are 10 in the TEMP table.

Connect()
sel("Select * from Temp")
While dr.Read
