Forms Data Controls :: How To Determine Excel .XLSX Version From Uploaded File
Aug 10, 2010
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 uploaded a new version of my website. and some users complained that they see some page i changed very very wrong. anyway after a refresh they see it fine. i think its because my css file got cached by them on an earlier time...why isnt the browser downloading the css file by himself on first load?..

Excel cannot open the file "Report.xlsx" because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file

Using the Interop for Excel 2003 I had a nice little link that saved or opened the repeater content as .xls. Now we are using Excel 2007 and I get file format error messages. When I click the OK button on the error pop-up Excel closes. Does anyone out there know how to convert my code to handle the .xlsx format? I've been reading up on Interop for 2007 but none of the examples seem to work for this particular simple task. Here is my code from the "Export to Excel" button click:
Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
' Send HTTP headers that specify Excel filename, MIME type, and character set
Dim sTemp As String = "attachment;filename=CoverageCase" & Session("OpenCase").casekey.ToString & ".xlsx"
Response.AddHeader("content-disposition", sTemp)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
' Create objects used to render the controls
Dim strw As New System.IO.StringWriter........
I found a thread from a couple of years ago dealing with this but there was no solution [URL]. There were a couple of tortureous work arounds but neither work for me.

The code Export data from GridView to Excel is working fine but in our office network all machines have MS Office2007 so when user click to export data and save the file it is always saving in the old format and when user wants to open that excel file then a popup asks the compatibility of version to open yes or no. So to open the file user everytime click Yes.
I just want to export data from GridView to Excel in MS Office 2007 version, so that when user click to open then it directly open the file without asking any question.
Following is the code which I used in my projects's web pages:
Therefore I cannot try any other code. I just want minor ammendment's in this code to accomplish this task.

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.

Is it possible to determine the HTTP protocol version (e.g. 1.0 vs. 1.1) used for a request within a .ashx handler? I can see all of the header information except for the version in Request.Params.
If not, what avenues are available to discover the HTTP protocol version when processing an HTTP request in ASP.Net?

I need to determine the clients .NET framework version in my web application. I'm running in partial trust so I can not read the filesystem or registry (Is there an easy way to check .net framework verison using C#?).
System.Environment.Version returns the runtime version, so I can not use that.
I cannot use javascript The only way I can think of at the moment is to try to load a .NET 3.5 dll and catch an exception, but this does not.
Update:
Request.Browser.ClrVersion and Request.Browser.GetClrVersions() will return the .NET framework version(s) installed on the client.
