So this is the problem I encountered. I am converting an old Excel macro to excel add in so that I can share it with my colleagues more easily. I am VB Newbie to .net, but I’m doing what I can, so please relax me.

I have a Windows form that allows users to enter data, and when they click the enter data button, The data should be transferred from the form to a specific worksheet. The code is as follows:

Imports Excel = Microsoft.Office.Interop.Excel

Public Class Form_CutListEntry< br />
 Dim xApp As New Excel.Application
 Dim wss As Microsoft.Office.Tools.Excel.Worksheet


 Private Sub Btn_InsertJobInfo_Click(sender As Object, e As EventArgs) Handles Btn_InsertJobInfo.Click
 wss = xApp.Worksheets("Job Info")

'Check that all data is entered
 If Trim(TxtBx_CustomerName.Text) = "" Then
 TxtBx_CustomerName.Focus()
 MsgBox("Please enter a Customer Name")
 Exit Sub
 End If

 If Trim(TxtBx_OrderNum .Text) = "" Then
 TxtBx_OrderNum.Focus()
 MsgBox("Please enter an Order Number")
 Exit Sub
 End If

 If Trim(TxtBx_CutlistAuthor.Text) = "" Then
 TxtBx_CutlistAuthor.Focus()
 MsgBox("Please enter your initials")< br /> Exit Sub
 End If

'Write data to excel worksheet. 
 wss.Cells(3, 1) = "Customer Name: "+ TxtBx_CustomerName.Text
 wss.Cells(4, 1) = "Order Number: "+ TxtBx_OrderNum.Text
 wss.Cells(5, 1) = "Todays Date:" + TxtBx_TodaysDate.Text
 wss.Cells( 6, 1) = "Cutting List Prepared By: "+ TxtBx_CutlistAuthor.Text

 Exit Sub
 End Sub

(Note that I took out the comments and some irrelevant So the detailed error message below contains the wrong line number)

I can open the form from excel, but this happens when I enter some data and click enter data:

An exception of type'System.Runtime.InteropServices.COMException' occurred in Toms CutList Maker.dll but was not handled in user code
Additional information: Exception from HRESULT: 0x800A03EC

In this line:

wss = xApp .Worksheets("Job Info")

Does anyone have a chance to point out my writing direction?

If anyone is interested, here is the complete error details:
