Create A Large Excel Spreadsheet?
Jul 28, 2003I'm using vb.net to create a large excel spreadsheet, im collecting the data from a mysql database, i have retrieved all the data and have all my data in excel.
The idea of the spreadsheet is that it is never seen so excel_app.visible is set to false.
i can get the excel spreadsheet to print and close using:
excel_app.activeworkbook.printout() excel_app.ActiveWorkbook.Close(False)
the problem I have is that i need to print the document in landscape.

View 3 RepliesHow To Create Pivot Table On Excel Spreadsheet
Jan 7, 2009How to create a pivot table on an Excel spreadsheet via code. The reason I took so long is because I added a reference to the Excel Interop 12.0, rather than the Excel Interop 11.0. I assume that 12.0 is for Excel 2007, while 11.0 if for 2003 (or whatever I have). If that assumption is correct, this will cause me a bit of trouble, as all the people using the program are in the process of moving from 2003 to 2007, and I should have moved myself, but didn't for some reason unknown to me (I thought the upgrade was pushed out to my computer when I was at work, but I don't seem to have it anymore). However, my concern is that the objects needed to create a pivot table in the 12.0 library are significantly different from the objects needed to create a pivot table in the 11.0 library.
I don't believe I can late bind to solve this, because there will need to be different steps taken depending on the version, since the objects have different interfaces. It appears to pertain only to pivot tables (for what I'm doing), as I was able to create the workbook, the worksheets, and export all my data with some old code that I had, and all of that worked with both libraries, the difference is just with the pivot tables because the interfaces have changed, such that the methods needed for one library don't even exist in the other one (and the code crashes, but that's probably because I have the PIAs for 2003 installed, and not 2007).

View 3 RepliesOleDbException 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"""

Calling Up An Excel Spreadsheet?
Jan 22, 2009if any of you have called up excel spreadsheet data within your VB.net 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

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. I am trying to determine the best way to do this, since I have never actually done it before. It seems like it should be simple, but as I am reading about it, I feel like it is a little more complicated than I had originally thought. I don't need to create the spreadsheet, I just need to add to it using this form as an interface.
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?

View 1 RepliesDisplaying An Excel Spreadsheet From A Button?
Jan 24, 2012Basically 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.
