Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:"
OpenFileDialog1.Filter = "CSV files (*.csv)|*.CSV"
OpenFileDialog1.FilterIndex = 2

I have a spreadsheet, in XLS format, that I wish to import into a DataGridView.
Here's my info: Vista Home Premium 64-bit, VB 2008 Express Edition, DataGridView1 is the visible control in the form.
I've read and tried a whole whack of code to connect to the XLS file and I always receive an error message. I will post again shortly what those messages are.

View 2 RepliesI 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 have several DataGridView controls populated with data. I want the ability to export all the data from these populated controls to 1 XML file. In effect the controls are populated after my project runs. The user will be given the option to export the data.
I then in turn want the ability to import this same data back to these empty controls at a later point in time. I would run my project in a different mode which would display the empty controls. The user would be given the ability to uploaded the XML file and repopulate the controls.
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 need the output in desired format as shown in image2. Check the attachment. This should work for any number of records.
Major problems with the Schema. I am using the DataGrid and not the VB Express 2010 DataGridView. Using code to make a new DataSet and DataView. What is confusing me is when adding Items after right clicking the application in the Solution Explorer, the add items shows DataSet, Xml To Schema, and Xml File. It is obvious that I don't know how to generate an xsd file that I can read into a code generated DataSet. If someone is familiar with xml and VB Express2010. how to generate an xsd file using DataGrid instead of DataGridView that I can read into a code generated DataSet?

I'm trying to import a tab delimited file into a table.The issue is, SOMETIMES, the file will include an awkward record that has two "null values" and causes my program to throw a "unexpected end of file".For example, each record will have 20 fields. But the last record will have only two fields (two null values), and hence, unexpected EOF.
Currently I'm using a StreamReader. I've tried counting the lines and telling bcp to stop reading before the "phantom nulls", but StreamReader gets an incorrect count of lines due to the "phantom nulls".I've tried the following code to get rid of all bogus code (code borrowed off the net). But it just replaces the fields with empty spaces (I'd like the result of no line left behind).
Public Sub RemoveBlankRowsFromCVSFile2(ByVal filepath As String)
If filepath = DBNull.Value.ToString() Or filepath.Length = 0 Then Throw New ArgumentNullException("filepath")
If (File.Exists(filepath) = False) Then Throw New FileNotFoundException("Could not find CSV file.", filepath)

I've tried using SSIS, but it encounters the EOF unexpected error.
