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.

I need to load an EXCEL file into my datagridview. However, my header row contains merge cells, which are not display correctly when loaded into the datagridview. Does anyone knows how to load merge cells correctly into datagridview? When the merge cells are loaded into the datagridview, they are displayed as individual cells instead of merged ones. I am using Microsoft. ACE.OLEDB.12.0 as the provider with Visual Studio 2008 .NET Framwork 3.5, EXCEL 2007.

I am importing data from Excel to a datagrid in VB, I can get the data on there no problems and also save this back to a SQL database without any problems.
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.

In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:
Using con As OleDbConnection = New OleDbConnection(cs)
'
'open the OleDbConnection
[code]....
The commented out code (below the 'Todo: comment) causes a additional table, but I want to change the table with the data.

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

I am trying to make part of a form program do the following When I exit a text field, I want to import some datainto a datagridview control.The columns are (1)Key, (2)Location, (3)Part Number, (4)Serial Number, (5)Description.There are up to 1000 rows of data in anyone of the spreadsheets I am working from.By using a datagridview, I can click the header and sort the data by either of the 5 columns, and when I select a data row, the Key number is reported back (for now, into a text box)I will be using the key number to further manipulate the spreadsheet after I have solved this problem.There are thousands of articles on DataGridView, and over the past 8 days, I think I have read them all. I have tried many downloadable routines, which haven't populated the DataGridView at all.Please can someone show me a simple program which will do the above task, and will give me a base to start from.I am running MS Office Pro plus 64-bit on Windows 7 and Visual studio 2010 pro

how would it go to be able to use in a VB application some statistical functions that are in Excel?
Basically I would just want to know the general lines of how something like that goes, what things need to be imported and so and whether this is a very complicated thing or rather it is just about importing stuffs. I have found something like this (which extends itself ) . I get tons of error red lines that never seem to end despite correcting using the options, new ones appear etc

Im having strange problems when importing data from an excel file into a sql table. Everything seems to imports ok until i look at the data in more detail, this is when I notice its imported the data but in the wrong order. for some reason when I look at the db table all records are in the wrong order, and strangely enough it seems to be a different order every time I import things. Is there a way to force the routine to import the data in the same order as the it is in the excel file?, because at the minute it seems to have a mind of its own.
My code is below:
Public Function ReadExcelFile(ByVal sFileName As String) As Boolean
Dim oSQL As New clsSQLHolder
Dim excelCon As String
