How To Import Excel Spreadsheet To Bound DataGridView
Jul 21, 2009
I'm trying to import an excel spreadsheet to a bound datagridview. I have a second form which I do all the importing from and update Form1's datagrid view. This part works great. Now, I am trying to update the table that the DGV is bound to, but cannot seem to get it. I know it is probably a simple Update command (which I've tried) but everything fails. It is confusing to me because I create a second dataAdapter and dataSet to import to, then set the BindingSource of the DGV to this new ds. Ideally, I want the Bound table to be empty, then require the user to import on the first run. After that, the imported list would always load.
Here is the code I use to import to the DGV and it works:
vb.net
Dim ds As New DataSet
Dim da As OleDbDataAdapter
Public Sub importDBButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles importDBButton.Click
OpenFileDialog1.InitialDirectory = ""
OpenFileDialog1.Title = "Select the Excel File to import from"
OpenFileDialog1.Filter = "Excel(*.xls)|*.xls"
[Code] .....
My DGV on the first form has a manually added column at index 0 that is a simple graphic. Not sure if this is causing errors, but thought I'd mention it. The spreadsheet that is imported is only 2 columns of the DGV. Do I have to specify data for the other columns? (There's about 16 and I didn't want to have to require the user to fill all that data out in the spreadsheet). How to save this imported data to the bound table?

I wanting to try and develop a form that will allow me to import an excel spreadsheet in to a datagrid view, can do that bit with this, Vb.net Information. what i want to be able to do is select which columns in the spreadsheet go where so say i have a spreadsheet with;
ProductCode, ProductName, ProductDescription, ProductCost and ProductMaker
In my DataGridView i have ProductName, ProductCost and ProductDescription.Is it possible to get a list of the columns in a spreadsheet that have text in and then either have a combobox that you select a value from and then after pressing a button it then imports the selected details in to the correct format, (Like mail merge)

I am trying to import data from an excel file but the spreadsheet name is causing problem. If I use 'Sheet1' as the name of the spreadsheet from which I want data, then it works fine but I want to change the name of the spreadsheet to the name which has spaces like 'PROJECT SHEET'. Please guide
Dim ExcelFile As String = "C:ProjectFile.xlsx"
Dim myDatabasePath as string = "C:ProjectsDatabase.mdb"
Dim excelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + ExcelFile + ";Extended Properties=""Excel 12.0 Xml;HRD=NO"""
Dim excelConnection As New OleDbConnection(excelConnectionString)
excelConnection.Open()

I'm currently trying to import data from an Excel document to a list in Visual Basic 2010 Express. The Idea is to have the data easily modifiable by the users. I have looked quite a bit online and all of the examples seem to reference either an "Imports Microsoft.Office.Interop.Excel" or "Imports Excel". When I try to use the I get "(no correction suggestions)".

I have to write an application in Visual Basic.Net that will open an excel file, run through the contents an export a test file for processing.
The application works great for me (Windows 7) but when transferred to a WinXP PC gives the following error: HResult 0X800A03EC
I can replicate this error by making the Excel Application visible so it seems like it is an issue where it can't access the file because it is open. Error occurrs when trying open the workbook.
Original Code
Dim excel As Excel.Application
Dim wb As Excel.Workbook

I have a datagridview which I would like to be able to export the information to an Excel spreadsheet, and be able to reload the information later on from a specified worksheet. Also, I'd like to avoid using Databases with Access etc because I am aware that some of the machines I'll be deploying the program on do not have Access installed and would not want to have to install it either.

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

My basic set up is Visual Basic 2010 Express on Windows 7 64 bit What I'm trying to do is to have VB 2010 get the data from a Open Office spreadsheet. I have looked around on the general interenet and have found quite a few references to MS Excel, but none dealling with Open Office. The code samples I have tried to use seem to rely on MS Excel being installed (Which I dont have). The 'Automate excel' page (Here: http://support.microsoft.com/kb/302094) naturally seems to rely on a Microsoft Excel Object Library reference that, not surprisingly, isnt there because I dont have MS Excel. Keep in mind I havent mucked around with a programming code for decades!
What I do have is Open Office 3.2, which CAN save spreadsheets in a excel format (.xls), and a few others such as .ods, .dbf and .xml (Excel 2003?).

if any of you have called up excel spreadsheet data within your VB.net app. Is it at all possible instead of calling up access and the like?
And just before some overzealous person puts "we will not do your work for you blah blah blah......" Im not asking you to write it for me, im just asking if its possible, has anyone succeeded in doing so?
Id rather not use VBA script if possible, Id like to create my own app and use a spreadsheet that has all my workings on already - sorry if its a bit noobie to ask such a daft question but one of my friends is going to be opening a restaurant soon and asked me if i could do a little prog for him using his excel stuff

I am trying to write a program that will display an excel spreadsheet in Visual Basic. My goal is for the program to display this Work Order Form I have designed in excel and to modify user, date and auto assign a work order number. After that is done I would like to print the excel form. So I guess my questions are:
- How can I display an excel spreadsheet in win forms
- How can I print the spread sheet after it is modified
- Is there a better way I should be doing this

In my latest project, I'm iterating through an Excel Spreadsheet and importing the information from it into a DataSet row for row. Based on certain conditions (namely, the text in a certain column on the spreadsheet). For certain conditions, the app is to write the row into a new spreadsheet and email that spreadsheet as an attachment to a pre-defined email address.

I am taking a pre-existing excel spreadsheet and inserting a blank row at the top. This part works, the part I am having problem is the fact that based on the code I have, I have to open the spreadsheet so when you execute the code the spreadsheet opens. Then when done, close it. When I try to close it wants me to save the document, even if I call the save method. This whole process should happen behind the scenes so I really don't want the spreadsheet opening.
See code below.
moApp.Visible = True
oWB = moApp.Workbooks.Open("I: estcsv.xls")
oWB.Sheets("testcsv").Rows("1:1").Select()
moApp.Selection.insert(xl.XlDirection.xlDown)
oWB.Save()
oWB.Close()
'When call the close, it still asks me to save the spreadsheet even though I called oWB.Save above.

I'm creating an application in VB 2008 that will act as an interface for user's to add information to an excel spreadsheet. I am trying to determine the best way to do this, since I have never actually done it before. It seems like it should be simple, but as I am reading about it, I feel like it is a little more complicated than I had originally thought. I don't need to create the spreadsheet, I just need to add to it using this form as an interface.

I am creating a report and outputting the results to an excel file. Here is how it is suppose to work. I have a table called EMPID that has a list of employee id's. I loop through this table and for each EMPID, I run several queries. I would like to append the data that is returned to the spreadsheet so that the results for all EMPID's would be added to the spreadsheet. Right now, the way I have coded it, for each EMPID it overwrites the fields in the spreadsheet instead of adding/appending them to it.
Here is some code:
If EmpidDS.Tables("EMPID_Table").Rows.Count <> 0 Then
For Each dr As System.Data.DataRow In EmpidDS.Tables("EMPID_Table").Rows
'Set the variable EMPID to the current row EMPID
EMPID = dr.Item("EMPID")
'Check that table is not empty
