The file you are trying to open 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?
When yes is clicked it opens in excel but in some other format I think for I cannot AUTOSUM or sum the values result always as zero for numbers appears as text as " 222" . even if i try to format cells with numbers it does not works.

I have a web page with a gridview control and a button for Exporting to Excel
I get following error when exporting to Excel.
"The file you are trying to open, 'someFileName[1].xls, 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. Do you want to open the file now?"
Clicking Yes opens the file. I would like to avoid showing the above error to the users.
Following code is used from the click event. I've left the commented code here to show what I've tried based on results from internet search. I have Microsoft Office Excel 2007 on local PC.

I'm working on a web app and need to stream various files. I can do pdfs, images, and older Office documents. However, when I try to do with 2007 documents, it breaks. Here is my code:
Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
switch (FileExtension.ToLower())
{
case "pdf":
Response.ContentType = "application/pdf";
break;
case "doc":
Response.ContentType = "application/msword";
break;
case "docx":
Response.ContentType = "application/vnd.ms-word.document.12";
break;
case "xls":
Response.ContentType = "application/vnd.ms-excel";
break;
case "xlsx":
Response.ContentType = "application/vnd.ms-excel.12";
break;
default:
Response.ContentType = "image/jpeg";
break;
}
Response.BinaryWrite(buffer);
The error that I get is:
An invalid character was found in text content. Error processing resource 'http://DomainName/GetFile.aspx.

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.

In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?

I have a page that does an upload of an xlsx file to a datatable and write into SQL.
That is working, my problem is when i upload the file and pass the values to the datatable some of them are showing in the wrong format and the column name dont
appears.
e.g.:
Hours at home
Hours working
3:00
8:00
01-01-1900 1:35:00
01-01-1900 2:35:00
01-01-1900 3:35:00
The first 2 columns its how i want the info the third is how my problem looks like.
I've tested and the problem occurs when the same column has more than one value.
The format of the cells is h:mm if i change it to text it works fine but i dont want that because the time will be converted to semething like this 0,123456789.
I dont know if it matters but the xlsx file is kinda complex and has 10,2MB.

I've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.

I am loading documents into our Oracle database and then retrieving them for the users to view. So far PDF, DOC, XLS, CSV, etc. all perform as expected, however; DOCX, XLSX, etc. files have one annoyingly persistent issue. When the document is downloaded by the user and they open it you get the first in a series of messages: The file 'thefile.docx' cannot be opened because there are problems with the contents. Details: The file is corrupt and cannot be opened. and then: Word found unreadable content in 'thefile.docx'. Do you want to recover the contents of this document? If you trust the source, click Yes. After clicking yes the file opens and all of the content appears correct. Including images, formatting, tracked changeds and comments, equations, etc. I have tried multiple methods along these lines to no avail. I simply want the files to open without the false-positive error messages. I am using VS2010, with the website targeted at .Net Framework 2.0.
objConn =
New
OracleConnection(gstrConnectionString)
objConn.Open()
cmd = New

cmd.Connection = objConn
cmd.CommandText = "select DOCUMENT_NAME,DOCUMENT_TYPE,DOCUMENT

When i export the data table to excel 2003 i get the output in a very fast manner and when i want to use the same in excel 2007 debugging gets stopped and nothing happens.... It does not show any errror on it to. When i slowly debugged i find that in saveas() it takes longer time and it seems like execution gets stopped in this process.
Its like in new window it shows loading for more than 10 min and after some time the particular window gets closed and nothing happens can anyone tell me what can be wrong.When the same code works great when i export to 2003.
