OleDbException Saying Spreadsheet Is Full When Inserting To Excel Spreadsheet
Nov 11, 2011I 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"""

How To Insert Row At Top Into Excel Spreadsheet
May 7, 2010I 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.

Add Information To An Excel Spreadsheet Using 2008?
Feb 11, 2011I'm creating an application in VB 2008 that will act as an interface for user's to add information to an excel spreadsheet.

View 1 RepliesAppend / Add Output To Excel Spreadsheet
Feb 24, 2011I 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

Asp.net - How To Mimic An Excel Spreadsheet On A Website
Jun 19, 2012I 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?
