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"""
I'm trying to export a datagridview to Excel and open the Excel spreadsheet (not SAVE the worksheet).
Public Sub ExcelRpt(ByVal DgvName As GridView, ByVal url As String) Dim xlApp As Microsoft.Office.Interop.Excel.Application Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
if 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
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
ive got excel spreadsheets that i would like to open in my windows forms as part of my program,ive put an Axspreadsheet on my page but how do i open up an excel file into it. Looking at opening the whole of the data so all the worksheets and workbooks and what not. User only need to "look at it/browse it" so to speak.elimintate a problem wit hreading a writing issue to excel ive got, using different pcs and get and im not allowed to set up a "trusted area", so everytime i open the excel file itself i get an error saying cant use the "characters ! %&*<>
" and is your filename less than 218 characters.ive finished coding for today, so will be on tomorrow.
Ive been trying to figure out how to find the next empty row in an excel spreadsheet.My project is a VB project, written in Visual Studio 2010 Express.What i need to do is open the spreadsheet (that is predefined) and find the next available row. (in column A through to S)My code so far for this little part of my prject is:
Dim xlApp As Excel.Application Dim xlWorkBook As Excel.Workbook Dim xlworksheet As Excel.Worksheet
The same as "Selection". I get a blue line for "ActiveCell" Doesn't work.
In my latest project, I'm iterating through an Excel Spreadsheet and importing the information from it into a DataSet row for row. Based on certain conditions (namely, the text in a certain column on the spreadsheet). For certain conditions, the app is to write the row into a new spreadsheet and email that spreadsheet as an attachment to a pre-defined email address.
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") 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.
I am exporting crystal reports information into an excel spreadsheet and now I am trying to open up excel so that the user can view the page but however I cannot SEE the excel file. in Task manager there is EXCEL.exe which shows that maybe excel opens up but the spreadsheet is not visible.
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 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.
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] .....
i have an Excel spreadsheet which I have exported to a Gridview. In my code the table name has to be declared i.e its the name of the worksheet. How can i export excel and select which table i want without hardcoding the table name. i have many worksheets and want to the user to select which table he wants from one workbook. I am using vb and have a web form.
Is it possible to deliver an Excel Spreadsheet via an Web Service. I believe not as ASP.NET web services seem only to deal in Serializable elements which the excel binary format isn't (I think). If the Excel is saved in XML format will this work?
I have a number of reports that will be emailed, but the request has been put into allow these reports to be pulled via Web Services.
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?
I'm thinking about how best to accomplish the following and wanted to see what others suggest.I'd like to capture an Excelworksheetnd save the area that has been edited (vs. the area thatremains blank)s a PNG image. This would ideally be achieved through an Excel add-in.
I would like to see some code/tutorials on reading an excel spreadsheet (a calender) into VB.NET. I'm pretty much okay from there. I want to convert it to an HTML table and output it into an html file for inclusion on a website.Where can I find tutorials OR can someone post some code with a desciption to get me startd?Is there a better way to include a xls file in a webpage?
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.
I have many folders. Each folder contains an excel spreadsheet file. Path is as follows:"C:DU1212DU1212.xls"Folder are named as DU1212 only the numer 1212 changes for every folder.Excel files names inside these folders are named similarly such as DU 1212.xls
I am programming this application right now that will more or less enter data into an excel spreadsheet's cells. This is my own program, it is not using Excel to write this program or function. I just wanted to clear that up.
What would be the easiest way for me to take a .xls file with my program and write values to cells in the file (and open up excel)?
What I was wondering is if I had a ListView1 with 1 row and 5 subitems, could I export that whole row into an Microsoft Office Excel spreadsheet, by defining in which Excell row/column I want to add each subitem into?
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.
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.
I am trying to import data from an excel file but the spreadsheet name is causing problem. If I use 'Sheet1' as the name of the spreadsheet from which I want data, then it works fine but I want to change the name of the spreadsheet to the name which has spaces like 'PROJECT SHEET'. Please guide
Dim ExcelFile As String = "C:ProjectFile.xlsx" Dim myDatabasePath as string = "C:ProjectsDatabase.mdb" Dim excelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + ExcelFile + ";Extended Properties=""Excel 12.0 Xml;HRD=NO""" Dim excelConnection As New OleDbConnection(excelConnectionString) excelConnection.Open()
I wanting to try and develop a form that will allow me to import an excel spreadsheet in to a datagrid view, can do that bit with this, Vb.net Information. what i want to be able to do is select which columns in the spreadsheet go where so say i have a spreadsheet with;
ProductCode, ProductName, ProductDescription, ProductCost and ProductMaker
In my DataGridView i have ProductName, ProductCost and ProductDescription.Is it possible to get a list of the columns in a spreadsheet that have text in and then either have a combobox that you select a value from and then after pressing a button it then imports the selected details in to the correct format, (Like mail merge)
I've got this problem of importing excel data to MySQL database. I want to create a VB.net application that allows the user to browse the excel file then click upload and automatically all the data in the excel file will be saved into the database.
How to keep original format from excel spreadsheet when displaying the spreadsheet on the datagrid in VB2008?I am using OleDbDataAdapter for importing the spreadsheet. However, the displayed sheet on the datagrid is different from the original excel file. I want to keep the orignal format.
Anyone know of some code out there that does this already? I have a bunch of pages with data grids on them in an admin website they want to export them to Excel, was hoping someone had this written already
I 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 :
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?
