Excel Spreadsheet Opens With The Error "this File Is Not In Recognizable Format"?

Apr 9, 2009

[Background]:I created a Winforms App that reads data and spits it out into an Excel Spreadsheet. On my computer, I have Microsoft Office 2003 and inside of the Visual Studio Project, I referenced COM Object "Microsoft Excel 11.0 Object Library". The Executable is on a shared directory and end users can run the application and generate the reports themselves.

[Problem]:Problems arise when an end user with Microsoft Office 2007 runs the application, generates the Excel Spreadsheet and sends it to someone with Microsoft Office 2003, the Excel Spreadsheet opens with the standard "this file is not in recognizable format" error and when you push "ok", the data shows up as symbols (garbled text).

[Question]When I reference "Microsoft Excel 11.0 Object Library" in my project, how does the .Net Framework (or my Application) find this COM Object object when it is ran from another CPU?I guess, I would like to know how references work. When you reference DLLs in a VS.Net project, compile the program and then put the execuable on another PC, how does VB.Net go about finding those DLLs you referenced or is it part of the compiled program?

I suspect when a user running MS Office 2007 runs my app, it is running a 2007 dll instead of a 2003 dll.However, I would think an error would be thrown if this was the case.

VS 2005 : Error In Opening An Excel File : Old Format Or Invalid Type Library

Feb 24, 2012

I am trying to open an Excel file using the following commands:

xlsWB = xlsApp.Workbooks.Open(filename, , True)

where 'filename' is the name of the file.However I am getting the following error message:

Message = "Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))"

I originally developed an application where I used the above code with default language setting of "English" (under regional and language settings). When I am changing the language setting to "French", the above errror comes up. I am changing the language setting to French in order to simulate an error when this application is run in a French version computer.

I'm trying to use LINQ to XML to create an Excel spreadsheet. I created a template spreadsheet, exported it to XML, pasted the XML into my code and then began to edit it. When I try to create a set of XElements using LINQ, I get these errors:

The first squiggle under <Cell> says "attribute specifier is not a complete statement"
The second under ss says "'>' expected"
The third under Type says "'Type' is a type and cannot be used in an expression"
Ignore the error under "Lot 1..." I will be putting an expression hole there.

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"""

Excel File Save In Office 2007 Format?

Mar 1, 2009

I'm developing a small application that creates Excel files with user details. I'm developing this in vb.net 2008 express edition under Windows XP SP2 and with Office 2003.My target PC is running Windows Vista. I'm able to run my program without any problem and even the Excel files get created without any problem on this PC.However, the problem is when I try to open one of these created files in Vista, I get a message like below:

"The file you are trying to open, "TestMe.xls", is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" If I click yes, it opens up properly. This is a headache as it opens up in my developing PC without any hassle. I'm sure its something to do with the Excel reference I've made in my PC (which is running Office 2003).How best can I save this file so it opens up in Excel 2007 without the above message.

Excel 2007 Macro Opens Access Db But Then It Disappears?

Sep 24, 2009

This code worked fine in Excel 2003, but since upgrading to Excel 2007 (Office 2007) it's not working. In Excel 2003 it opened the access db form and stayed open. In Excel 2007, you can see the db open, then the form, but then it immediately closes. I've checked to code and it still works fine in 2003. Can anyone tell me how to fix this? Here's the code:

Calling Up An Excel Spreadsheet?

Jan 22, 2009

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

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")
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.

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")
