View 1 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"""

Deploy WindowsApplication That Contains Subclassed DataGridView
Jul 8, 2011I would like to know the correct procedure to deploy windows application in VS-2005.
There are some specific issues I am facing after deploying the project to the client machine.
- I have a CMS (ContextMenuStrip) in one of my forms associated with a TreeView and its not showing.
- Another form that contains a custom DataGridView which i created by subclassing default DataGridView is not showing this control.
DETAILS:-
- Everything works fine on my machine.
- I BUILD the project in the RELEASE mode
- From the bin\Release folder copied the .exe to the client machine in the root, also copied the Reports to the root on client. Is this correct way to deploy?
- Instead of setting the CMS property of the TreeView, I instantiated a CMS in my form, assigned it to CMS property of TreeNodes when TreeNodes are populated programmatically.

Using Dropdownlist In EXCEL Spreadsheet For Web Form?
Feb 9, 2010I have an issue that I am trying to work around. I have an aspx page that needs to load up a formated XLS spreadsheet into a DIV tag and then allow the user to input data that will be retrieved later on postback and values store in a MS SQL database.
I created an excel spreadsheet and formatted it with the formulas and colors. I also added a combobox from the control toolbox. I also added a checkbox from the control toolbox to another cell. I then saved the page using File-->Save AS WebPage. I checked the 'Add Interactively' checkbox on the save dialog. I then opened the file in an editor and copied the object tag into my aspx page. Everything was fine except my combobox and checkbox did not appear in the HTML spreadsheet.
I am assuming that I have to EITHER programmatically add the controls prior to render or add the combobox as a XML element to the proper node of the XMLData value parameter attribute.the current XML Block for this node is :
<Row ss:AutoFitHeight="0" ss:Height="18.75">
<Cell ss:StyleID="s23"><Data ss:Type="String">Fund</Data></Cell>
<Cell ss:StyleID="s23"/>
[code]....
The second cell, between FUND and ENG is where I need to add the combobox. also how about binding data to this dropdown control control. This data is coming from SQL DB, and not from a range in the activesheet. Someone told me that I should use Access instead of Excel but I dont think that is right as I need spreadsheet capabilities on the page?
Convert Excel Spreadsheet Controls To VB Form?
Apr 3, 2010I am converting an Excel spreadsheet with VBA macros to VB. I have been able to export all of the VBA macros (.frm, .cls, .bas), but cannot figure out how to export the controls embedded on an Excel spreadsheet to a VB form (e.g. =EMBED("Forms.CommandButton.1",""). I have buttons, check boxes, list boxes, etc. embedded in an Excel spreadsheet. In the macro editor, I can see the controls in the object browser window. For example:
cmdPrvFirst As CommandButton
Member of VBAProject.Sheet1
Copy/paste does not work. How can I do this? I hate to have to create the VB forms from scratch.
Fill Windows Form Spreadsheet Control?

Apr 16, 2012i want to explore vb abit more and i want to create a VB application similar to a cash register in a cafe or a bar, mainly for touch screen computers/systems. I want this to be for a bar and have a vague idea on how to do it.
i dont want to assign a price statically to a button e.g 'Button1' = "Fosters 2.00" because prices are subject to change, i know this may be possible using a database but i have no clue about them, is there anyway to use excel maybe? and say 'button1' reads from the spreadsheet cell 'C1'.
Spreadsheet From DataTable?
Oct 20, 2009In my app, I'm downloading a spreadsheet from FTP, moving the data read from thespreadsheet to a DataTable, and, depending on certain conditions, emailing a new spreadsheet (one that contains certain rows from the 1st spreadsheet).My problem is creating the spreadsheet that will be mailed. I can't seem to work out how to add the row from the DataTable (originally from the spreadsheet that was downloaded) into the spreadsheet that's going to be mailed.DS.Tables(0).Rows.Add(ObjSheet.Range(workTable.Rows(i)) - 1)Is what I've got at the moment, but it's not working. workTable is the DataTable where the rows from thespreadsheet were copied to. DS is the DataSet where I'm putting the rows from the specific selection.

Feb 6, 2012So I'm a little rusty on my VB.NET skills, but I decided to take up a project to get me working in it again. Problem is I've hit a slight road block and I was hoping someone here might be able to point me in the right direction.I have a spreadsheet (or 3, but they could be combined if that makes it easier) that contain interest rates. I need my program to use user-input to select which interest rate it needs and then calculate and output the grand total, without the end user ever seeing or even being aware of the interest rate table.
View 1 RepliesApp Reads A Spreadsheet Into A DataSet With ADO.NET
Jul 23, 2010I'm writing an application in vb.net 2005. The app reads a spreadsheet into a DataSet with ADO.NET and uses a column of that table to populate a ListBox. When a ListBox Item is selected, the user will be presented with detailed information on the selected record.One part of this information isn't in the DataSet. I have to compare a column from the spreadsheet with several external data sources to determine the nature of the record in question. Here's where I have my problem.This comparison has to search through 9.5m rows in a SQL table at one stage. I've checked and there's no way to "shrink" the query down as I'm already only searching absolutely essential data.What happens is that the application never visibly does anything. The CPU usage shoots up to 100% regardless of what it was at beforehand and the system's performance becomes almost unbearably slow.Can anyone suggest a way I can improve this situation while this massive query is running? I was originally going to write the contents of the 9.5m rows in the database table to a text file which I'd then read from, but after 6.5m rows, I got an OutOfMemoryException.
View 2 RepliesCalling 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.
