Dim xlsApp As New Microsoft.Office.Interop.Excel.Application

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 need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

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

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.

View 1 RepliesI 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 am trying to open an excel file and write to it as data becomes availableI can create an instance of excel and write to the selected worksheet once. But, I can't seem to write back to the existing file. I keep on getting a null reference error when I try to send new data to the file.The function I am using will run once, but when it returns to the main form, I lose the values of xlApp and xlWorksheet. It appears that going in to the function makes the original values null.
View 2 RepliesI found a few examples online on how to import excel into sql via vb. but can i do it via stored procedure?
Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',

'SELECT * FROM [SheetName$]')

'SELECT * FROM [SheetName$]')

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.

View 3 RepliesIm 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

I have a problem with importing an excel into a data grid.
Here is my code:
Try
Dim _Obj As New ExcelConnection.ExcelConnection
_Obj.ImportAttendence("c:Info_pc.xls", DataGrid1)
Catch ex As Exception
End Try
In the excel i have numers and text and "Service Pack", "Processor Speed" and "Numar procesoare(Number of processors)" and the values for these are numers. in the data grid when i import the excel those values doesn't appear, i receive the value "null".
I have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
I'm using VB Microsoft Visual Studio to try to open an excel file, clean a column of data, then load into a datatable for use by program (enter Excel data into Reflections, process / screenscrape, enter data into Access db).
I can load the data into a datatable just fine, but I'm having problems figuring out how to open the excel file BEFORE it's loaded into the datatable so I can "Clean" a column of data the program reads from that can potentially have hidden characters. Below is what I have so far.
