Forms - SQL Data To Excel Spreadsheet

Dec 24, 2009

So I need to create a windows form that is able to generate reports by querying a SQL Database or SQL Server. There is data in the databases that will be put into an excel file from whatever columns from a specific table I need. I need it to be a dynamic query that is probably hard coded into the application because I might need to write other queries at some point to generate different reports that need different columns.

What I need is somewhere to start or some code that I can look at because im not very familiar when it comes to vb.net/excel. I need code to get all that data from the database and put it neatly in an excel file and I would like to specify what columns in the excel file all the data goes under.

Manipulating Mutiple Excel-like Spreadsheet Data In .NET

Apr 21, 2009

I have an project which was written in VB6 and made use of the Spread3.0 component to display multiple large data from database in spreadsheet. My objective is to convert this project into a VB.NET current version which would not use the third party component but can possibly use a freeware that does similar if not all the functionality.

My question is, are there any freeware that is available in .NET for such spreadsheet-like manipulation of data programatically? I have come across dsoFramer but this only allows the display of the data in an IE frame. I would like to jus embed the content into my existing form.

Also this freeware must be able to handle formula and user-editing as well as multiple cell type such as combobox/checkbox etc.

Takes Data And Writes It To A MS Excel Spreadsheet?

May 25, 2007

I have a program that currently takes data and writes it to a MS Excel spreadsheet.  (automatically opens the program, creates the cells, and fills them with data)

I would like to add an additional feature to my program that offers support for OpenOffice.org's 'Calc' spreadsheet program. (so users without MS Excel can use the application) So I am basically asking if anyone knows how to automate OpenOffice 'Calc' from VB.net. (I am using Visual Studio 2005)

I have searched on the OpenOffice forums but no one seems to know the vb.net code for this. So I was wondering if anyone here has done this, or would know how to do this.

OleDbException Saying Spreadsheet Is Full When Inserting To Excel Spreadsheet

Nov 11, 2011

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"""

VS 2010 - Filling DataGrid Columns With Excel Data

Mar 26, 2012

I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView

Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.

So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)

Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.

I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text
