External Table Is Not In The Expected Format

Oct 12, 2009

I have a problem with open connection to Excel file. I use this open connection:

[Code]....

I use Excel 2007 to open the file and there is an error message "The file you are trying to open is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file." I don't know what is wrong with my code to create and save data to excel file ?? Or maybe something is wrong with my open connection?

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.

Intermitent "External Table Not In Expected Format"?

Apr 30, 2012

I have a program that is connecting to an Excel file using ADO.Net. It processes some html files and parses out certain pieces of data and enters it into the spreadsheet (either updating the record with recent data if the record already exists, or adding a new record if not). It seems like it works fine and I can process several html files successfully. But every once in a while the program will crash with the error that the "External Table not in Expected Format". When this happens, all I have to do is exit out of my program, open up the spreadsheet file in Excel, save the file, close Excel, and restart my program. Then I am able to continue processing files including the file that I was trying to parse when the program crashed.

The Spreadsheet is in Excel 2003 format, but I am using Office 2010, however when I am saving the spreadsheet I never get any boxes popping up about possible compatibility issues. I also don't have to do anything to the spreadsheet when I've opened it in Excel expect to resave it. Not sure if anyone has heard of this issue before or how I could possibly fix it.... If anyone needs code, I can post it, although because my program seems to function correctly most of the time, I don't think that there is an error there...

I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

Error Opening Excel File From .net 2010?

Aug 26, 2009

Dim excel As New Microsoft.Office.Interop.Excel.Application()
Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w))
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)

when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

Excel DataSet Error: GetOleDbSchema Table Require An Open And Available Connection

Jun 29, 2011

I'm creating a tool that will query Excel and intialize the default settings for the site's Cad Software.I want 2-20 users to be able to simultaneously query excel. Currently I have the spreadsheet open on one computer and the other test machine gives me this error.

GetOleDbSchema Table Require an open and available connection. The connections state is closed.

I could use some help on the code design. Should I use Datareader instead....Does that have less permissions issues? Or do I need to open up the oledbconnection in a different manner?

Excel 2007 Macro - Runtime Error 1004 After Saving And Re-opening A File

Oct 25, 2009

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.

I reopen the file.I enter in the name of a person on one line. I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file). Instead, in that first column of ratings, it instead gives me the following error:

Runtime error '1004'Unable to set the LineStyle property of the Border class

When I hit "debug" this is the code it points to:

If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!

note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected. it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

The last line throws an exception "Cannot open file" with certain end-user profiles. It works perfectly fine when executing from an Admin account.

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.
