Error Opening Excel File From .net 2010?
Aug 26, 2009Dim 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 2007 Macro - Runtime Error 1004 After Saving And Re-opening A File
Oct 25, 2009I 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.

Open/ Modify Excel Through ADO.net - Error: System.Data.Odbc.OdbcException: ERROR [42000]
Jun 22, 2010I'm writing an application that imports and tidy up address data into a cleaned, deduped excel workbook ordered in rows with each column as an address field. One of the issues I've ran into is that we sometimes get a workbook where the multiple address fields are held in a single cell with line breaks. I've written code to extract all of this data out of the excel sheet in to a dataset with each sheet as a table and the address fields contained within. I now want to create a new Excel workbook from this data with the address fields in Row and columns the problem I have is I can Open/create the Workbook but when I try to insert a new Sheet (Table) I get an error saying the Workbook is read only....

Opening Excel Files - Force It To Read As Text ?
Jun 11, 2010Application using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?

VS 02/03 - Using ODBC To Export Tables From A Dataset To Excel File Without Auto-formatting
Jan 22, 2010I'm using ODBC to export tables from a dataset to an Excel file without auto-formatting Excel or even needing to have Excel installed on the users PC. This works great but I just had a request to autosize the columns and make the header line bold. The only way I know of doing this is to fully automate Excel to control the row/column/cell formatting. Does anyone know a way of doing this without auto-formatting Excel?

Opening An Excel File
Apr 22, 2010My company is currently using a Linux/Powerterm program that exports reports via email on a daily basis. I have a add-in program installed on outlook to automatically save the report to a folder on the server. The file that is exported appears to be an XLS 97-2003 Worksheet, but I confirmed from the original programmer that this file is not a true Excel file, I believe it is a unicode file, but it can be opened by Excel. I want to link these files to an Access database within my form, but Access does not recognize this file format.I attempted to create several programs in Studio to convert the file to an XLSX file, but on each attempt I receive an error the file is an in unrecognizable format which is killing me at the moment. I even made attempts to dump the data to an dgv but it still wont be accepted.

Import Excel Data Into SQL Server - ERROR: "ODBC --Connection To {SQL Server} Servernamesqlservername Failed"
Aug 13, 2010I am trying to do something fairly simple.. allow my user to import thier data from Excel into SQL Server, where it can be used by the application.To do this, I'm using the fairly simple code that is common everywhere I look:
strFilePath = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fdlgFileOpen.FileName + ";Extended Properties=Excel 8.0"
connExcel = New OleDbConnection(strFilePath)
connExcel.Open()
[Code]...
Now, on my development computer this code works perfectly. The data imports, and I can go on my merry way.
On the TEST computer, this code throws the error: "ODBC -- Connection to {SQL Server} servernamesqlservername failed." This seems very odd to me, because I'm using exactly the same SQL Server and database to interact with the application, and all the other screens in the application work perfectly. The test computer CAN connect to this SQL Server, but it keeps throwing this error whenever I try import data from Excel.I've tried everything I can think of - using the server's IP address instead of the server name, sending the SQL Server administrator data along with the request, taking out the Trusted_Connection=Yes... nothing works. What is going on here? How can this code work fine on my computer, and hiccup on another?
