Append / Add Output To Excel Spreadsheet

Feb 24, 2011

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
[Code] .....


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"""

Calling Up An Excel Spreadsheet?

Jan 22, 2009

if any of you have called up excel spreadsheet data within your 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

Displaying An Excel Spreadsheet?

Feb 15, 2012

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

How To Insert Row At Top Into Excel Spreadsheet

May 7, 2010

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")
'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 don't need to create the spreadsheet, I just need to add to it using this form as an interface.

Jun 19, 2012

I am building a website to capture data. I have many spreadsheets that are used for data entry or capture. Now I want to mimic these complex spreadsheets on the web forms but I am unsure of the correct control to use.

Data entry must be allowed and live calculations also need to be made similar to formulas on normal excel spreadsheets. Later on the data must be captured into an SQL table.

What would be the best control to use or method to mimic that functionality, albeit that the spreadsheet component is no longer available in visual studio 2010. Is it a data grid?

Displaying An Excel Spreadsheet From A Button?

Jan 24, 2012

Basically the cells are displayed from Excel to the Visual Basic form, but once I press a button on the form to display the spreadsheet which contains the cell info, the spreadsheet won't display at all. (This I think is because the link has subsequently already called Excel). I've looked at the Task Manager and copies of Excel are already in the process, once these are deleted the spreadsheet can display from being pressed from a button on the form. How can I override this deletion method from the task manager so that the spreadsheet always displays properly from the form.

There is no other workaround at this point, so here is what I am attempting to do:

1.  Fill a DataAdapter from an Excel.xls spreadsheet.
2.  TRUNCATE an existing SQLServer2005 db table that matches this excel spreadsheet.
3.  UPDATE that SQL Table with the DataTable filled from the excel spreadsheet.

If there are anyother suggestions (OPENROWSET/DATASET is not possible for my situation, in or outside of a SProc),Here's the current dev point I am at --- no errors, but also the SQL table does not update.

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 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.
