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?
I am pretty good with HTML, PHP & MYSQL but this is my first go at working with a windows host and an ASP script. I recently purchased a script that matches my clients needs and when i have opened the folder to view the files its all double dutch to me apart from one css files which makes perfect sense to me!
Im stuck with is the database file included in the template, i ave been unable to import it into MSSQL using 'My Little Admin' which is the control panel provided by my hosting provider. Looking through the file with notepad it seems to contain the information for several tables but i cannot figure out for the life of me how i import it with 'My Little Admin'
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.
Iv created a web application using vb.net 2005. Its working fine and running fine on the server (Microsoft Server 2003). The problem i have is to dowload a file from the same server using vb.net. I tried using this code but it gives me a : "is not a virtual path" error.
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.
While exporting the html to Excel using Response.Write() in ASP.NET and when I try to save as the exported file I'm getting the default save as file type 'Web Page *.html, *.htm in excel application. Is there an any fix to get the default save as file type as xls or xlsx?
I am trying to fetching the data from Book1.xlsx file. The program is not working and throws an exception. check the code and tell me where I am doing the mistake?
[Code]....
The exception is:
An error: The Microsoft Office Access database engine cannot open or write to the file ''. It is already opened exclusively by another user, or you need permission to view and write its data.
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
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'm adding a reference to a funciones.dll file using
clr.AddReferenceToFileAndPath() because I couldnt get it to work other way with this file and it succesfully does it. The file is named funciones.dll and it's in the bin folder. But when I do
from funciones import *
I get "no module named funciones"
since the funciones.dll file it's a funciones.py file compiled, shouldnt the module name only be named funciones and no any other name? isnt the name the problem and it's another? I dont know what other info could be relevant here but if there is any let me know

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.

What's the best way to import a small csv file into SQL Server using an ASP.NET form with C#? I know there are many ways to do this, but I'm wondering which classes would be best to read the file and how to insert into the database. Do I read the file into a DataTable and then use the SqlBulkCopy class, or just insert the data using ADO.NET? Not sure which way is best. I'm after the simplest solution and am not concerned about scalability or performance as the csv files are tiny. Using ASP.NET 4.0, C# 4.0 and SQL Server 2008 R2.
I have been trying to import from an Excel file and insert it into a table. I can upload the Excel file. I can view the Excel file in a grid But when I run the import process to insert the rows in the Excel file I get only one row and it has all nulls except the dateentered and entered by field. I added breakpoints and tried setting a couple of the fields to labels and I could see that data was getting to the reader.
