I am importing an excel sheet into my sql database. Everything works fine, but I would like to read the column header in as static value. Not sure how to do this. Here is the code I am using to read the sheet in:
'Connection String to Excel Workbook
Dim excelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & MyFile & ";Extended Properties=""Excel 12.0;HDR=Yes;"""

View 4 RepliesI'm attempting to import an excel spreadsheet into a dataset. The spreadsheet is selected by the user by browsing for a file. I can get it to work properly only if I know the exact sheet name, but it varies from sheet to sheet. I need to tell it to always use the first sheet in the workbook.
I've declared the following at the beginning of my project:
Imports System.Data
Imports System.Data.OleDb
Imports Microsoft.Office.Interop.Excel
[Code]....
Currently I'm working on some code to modify a spreadsheet before it get's imported into SSIS, using a SSIS script task, so VB.Net.
However I'm having real trouble figuring out the correct code for doing a copy, paste as values for a particular range. In other words: my spreadsheet has formulas in it and I want to convert this to values before it gets imported. I have no trouble figuring out what it should be like in VBA, I just can't get it to work in VB.Net.
Does any one have a clue, or even better a code snippet on how to do this? I can find alll sorts of examples in VB.net for excel just no Copy- paste (as values) ones.
importing excel sheet data into a sql table(MS SQL 2008) via a datagrid and would like receive as much advise as possible, in order to learn more on this...

I am using this to connect my datagrid to the excel sheet and able to view the data sheet, but from here on.. I am not very sure on how to go about to transferring the excelsheet into a sql table.
I post a question similar to this a few days ago, but nobody answer. Now I modify my request a little bit, I want to read an excel file using VB.NET program. I know the logic below can do this. The logic is shown below.
But I have a question. This logic needs the worksheet name, but usually my application doesn't have this information, the worksheet name cannot be hardcoding. I have 2 request:Can I always upload the first sheet from the selected excel file. (ACCESS can do this without knowing the worksheet name).

I have an excel sheet that contains 25000 phone numbers listed in one cell with no sorting order. I want to create a small windows application that can read the sheet and return the total number of the phone numbers and how many duplicate numbers as well as the number of times of repetitions. How I can resolve this issue? What is the best way to approach it? I'm using VS 2008 and VB.Net.
View 14 RepliesMy requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example:
358218033354974
359473035499561
358218036156129
354022038366247
358218032490035
359473030516492
353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated):
Using connection As New OleDbConnection(sExcelConnectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
[Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to:
Get only first column of every worksheet
All values that are numeric
Skip empty values
Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.
I have an excel sheet with image names in column A. I have a directory (with subfolders) on my network with all the images in there plus some.I need to copy only specific files from one location to another.
View 1 RepliesI have managed to read a sheet from a excel workbook and pop it into a datatable.
Public Function GetSheet(ByVal SheetName As String) As DataTable
Try
MyDataTable.Clear()
[Code]....
My understanding is that if I make changes in the datagridview it is reflected in the datatable.
So now I want to write the updated datatable back to the appropriate worksheet.
I have read about "insert into" or "update" etc but it is very specific columns and rows.
One other thing, when I set the datagridview datasource as the datatable I get about 9 other columns such as TABLE_SCHEMA TABLE_TYPE etc. Any pointers wher thay are coming from and maybe how to get rid ofthem?
I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?
I'm trying to read rows in a DataGridView and the following error is thrown up. The DataGridView was filled from an Excel Sheet with a column of currency.

I have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?
