With this following code I get the this error: "The MS Jet database engine could not find the object 'Sheet1$' Make sure the object exists and that you spell its name and path name correctly." The name and path are correct, the error ocures in the highlighted statement. The sheet name is Sheet1

I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

In building an Excel workbook with VB.Net, is it possible to sort all the worksheet tabs into a particular order? I'm building a workbook with individual sheets named by drive letter, i.e., "C Drive", "D Drive", etc.

I have a macro run program I have created using excel 2007.The excel version makes use of VBA designed userforms and macro code to run and it stores data within a worksheet.It populates some of the fields in the userforms from drop down boxes whose pre-populated values are stored within another worksheet in the workbook.If I was to create this within vb.net how would the drop down box values be stored? and also: would it be easy to have the userform on-close click event send the data to be stored in an excel workbook ?

When I do Data Importing (CSV to DataGrid), everything runs normal except one problem.
CASE 1: If the Original CSV Data is: "ABC" It will appear as like ""ABC""
CASE 2: If the Original CSV Data is: O"K" It will appear as like O""K""
It will create extra quotes after importing into the datagrid. Does it related to Split() function?

However I have a new spreadsheet which has the same product listed again and again with the same description but different totals, what I want to do is to upload this to the datagrid just once for each description, with a grand total of all the seperate totals

I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()
[Code]...
After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.

I have been trying for several months (in my spare time) to write a vb.net (version 2010) program that connects to Excel (version 14) and imports numerical data.This data will be used later for engineering calculations.I have tried the Interop code which I have found on the internet with limited success and now I am trying the connection string method.I have found some examples of code, on the internet,that I have pieced together and can't get it to run.Below is that code.
Imports System.Data.OleDb
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].......
This is a screen image of the error I get when trying to run the program.

I need to import data from Excel worksheet into the VB.Net program. First, I need to get the data to some array or arraylist and secondly to show the data to user through datagridview or similar.So far, I have this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:TempTest.xls ;" & "Extended Properties=Excel 8.0;"[code].....
How can I adjust the code to manage that? And how can I import the same range to variables (the range contains approx. 200 rows and 30 columns of data points) and I need the flexibility to add or delete items (rows) from the data in memory later.

Is there a routine that will allow me to import data from an excel spreadsheet into a database within my project? I only need to do this to populate the the database I have created in my project.
While the project was being developed I used junk test data for testing and debugging but now I wan to populate the database with the actual records.
Here is the skinny:
In the project database I have the following fields:
ItemID - Primary key
SamCode
[Code].....
Column B contains the Full Name Data where B1 in a column header Column C contains the UPC Numbers needed where C1 is a column header
As stated this is a one time deal and not something I need to run as part of the application.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

This code works well however when data is exported to excel in one field some values are wrong. Instead for example populating 16-12-19 it populates 43815, 01-03-99 it populates 36220. Again, if the sort code is like 20-72-68 or 60-01-22 it is populated the same way, which is correct. If the value is a date lookalike then this problem appears, but if not then the exact value as displayed on the grid is shown in excel.
I inserted the code (highlighted in red) to set all the fields as text values. Right, it is exported and when excel spreadsheet is opened the field property is text, but the problem still exists. Why doesn't excel display it as it is displayed on the datagrid and database, instead of changing it even when set text.

I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code. Sort code in the database is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is disaplyed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.
