I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names. So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

I'm working on some code that generates an Excel spreadsheet server-side and then downloads it to the user. I'm using ExcelPackage to generate the file.
The generation is working just fine. I can open the generated files using Excel 2007 with no issues. But, I'm having trouble downloading the file with Response.TransmitFile().
Right now, I have the following code:
//Generate the file using ExcelPackage string fileName = generateExcelFile(dataList, "MyReportData"); Response.AddHeader("content-disposition", "attachment;filename=FileName.xls"); Response.ContentType = "application/vnd.xls" Response.Charset = ""; Response.TransmitFile(fileName);
When Excel 2007 opens the file downloaded as above, it gives the "file format doesn't match extension" warning. After clicking past the warning, Excel displays the raw xml contents of the file. If I change the file extension, like so Response.AddHeader("content-disposition", "attachment;filename=FileName.xlsx"); Excel 2007 gives an "Excel found unreadable content in the file" error, followed by a dialog that offers to locate a converter on the web. If I click "no" on this dialog, Excel is able to load the data.
I've also experimented with different MIME types, like application/vnd.ms-excel and application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, combined with file extensions of .xls and .xlsx. All combinations result in one of the two behaviors mentioned above. What is the correct combination of file extension and MIME type to use in this scenario? What else could cause this failure, other than an improper MIME type or extension? FYI, this is occurring with Visual Studio's built-in development web server. I haven't yet tried this with IIS.

I have a link http://Test/Folder/file1.xls which is working fine But if I typehttp://Test/Folder/file1.xlsx it is not working. It is giving me a file not found error.So when I read online every one is suggesting me to add the correct MIME type at tyhe IIS level. I don't know if that's the correct thing to do.I opened IIS and navigated to folder FOLDER right clicked and selected properties -> HTTP Headers -> MIME Types->New -> Extension -> .Xlsx-> What should i be entering for MIME type?
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.

When attempting to run a hello world aspx page it fails to load returning the message "Server Application Unavailable". The application even viewer logged the following:
Event Type: Error Event Source: ASP.NET 1.1.4322.0 Event Category: None Event ID: 1088 Description: Failed to execute request because the App-Domain could not be created. Error: 0x80070002 The system cannot find the file specified.
I tried to run aspnet_regiis.exe -i, rebooted but this did not work.
I tried to uninstall, reboot, reinstall .net from the Windows component section of Add/Remove Programs.
I have some code that successfully traps an error 404 and diverts to an appropriate page. However, I have a problem with certain types of error. My code will trap the scenario where a user types, e.g., www.mysite.com/indecks.aspx where no such page exists. However, if the user types something along the lines www.mysite.com/index.aspx/nonsensetext where index.aspx is a valid page, the page load event for index.aspx is triggered. However the page is rendered incorrectly because, I think, it is failing to find the images and CSS file associated with the page - perhaps because it is looking at the wrong path.
I expect that I can trap this by examining, for example, Request.URL.OriginalString and, if I detect garbage, I could re-direct to the same page "more cleanly" (i.e. without the junk on the end of the URL). However I'm a bit concerned that this is happening at all. Shouldn't this be treated as a 404 error?
I recently installed developer express and sql server 2008 express. I am trying to connect to the sql database but get this error. When I try to add a reference to system.data.sql, it doesn't exist. Did install sql server 2008 service pack 1 wrong or visual studio express service pack 1 wrong?
