Import An Excel Spreadsheet Into A Visual Basic Application?
Oct 28, 2009
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
[Code].....

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 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'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'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?

My application reads information from an Excel spreadsheet into a DataSet (ds1) which is then filtered into another DataSet (ds2) based on user-specified criteria. The information is basically telephone call logs that reflects when a phone call was made,what extension it was made one, how long the call was, what number was called, etc.When the user's "search" criteria is matched in ds1 above, the application adds the number called to a ListBox on the form. When the ListBox Item is selected, additional information (call duration and such) is displayed to the right of the ListBox. My problem is that a single phone number could have been called multiple times on an extension within the date range the user specifies and for each occurrence of that number in the ListBox, the "expanded" info only reflects the information for the 1st call to that number listed in the DataSet.
The only unique identifier I have is the DateTime field for the row (as this goes up to the second). I thought about putting it into the ListBox item, but I'd prefer that this date not be visible until the user selects the ListBox item to view the details for that call. [code]

I have a spreadsheet in excel with three headers:
Project Name The name of a project i'm working on.
Requested Role The job title/profession of the project employee. (example: mechanic, manager, engineer)
The name of the employee.When i click on the Person's name i want another page or tab (specific to this person) to appear showing details about them such as their name, job title, how long they worked, what project they are doing... etc. (similar to a Facebook profile)
When i click on the project name i want another page or tab (specific to this project) to appear showing details about it such as the requirements, the deadline, who is currently working on it... etc.
Furthermore, i would like to set up two levels of access:For the specific pages i was thinking of using the tab control but i want it so that i can search through the list of projects or names, select one, and then it brings up the page about it.The levels of access is the least of my worries.

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"""

I am building a business intelligence application for my organization. I have a form in which I would like to display existing excel spreadsheets. I have searched high and low for a control that would allow me to display a spreadsheet. Basically what I need is a viewer control that I can user to call the individual soreadsheets and display them in the form.I do not want to open excel outside of the application, but instead display the spreadsheet in the form as part of the application.
