How To Get The Csv Content In The File That Is Being Downloaded By The User
Dec 10, 2010
I am working on a web application and in ASp.Net using VB.net. The requirement is to create a csv file on the server and the user should be able to save the file on his machine. I am creating a csv file on the server and throwing the contents of the csv file to the user using Response.Write method.The problem I am facing is instead the csv file content, user is getting the html code of the page which he is accessing I wrote the following code in my aspx.vb :
strPhysicalPath = Server.MapPath("CSV/" & PathVirtual)
appendFileContents(AppStartupPath, "strPhysicalPath : " & strPhysicalPath)
Dim objFileInfo
As System.IO.FileInfo
objFileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
How can I get the csv content in the file that is being downloaded by the user?
Does anyone know if it is possible to measure when a file has been downloaded?
I place files for clients to download but there are two things I need to know. One is if the file has been downloaded at all at any point. Second is how many times the file has been downloaded. Can each file (usually but not always image files - sometimes pdfs) be tagged in some way to record what happens to it?
I am building an excel file using the OpenXml sdk 2.0. I am putting it in a memory stream and outputting it to the browser.The problem I am receiving is wiht IE 9 if I click Open it says "filename couldn't be downloaded". If I hit save/save as and save it to the filesystem, then open it, the file opens fine with no errors.
In Firefox regardless of if I use save or open the file when opened in excel says its corrupt.I already built the file by writing it to the filesystem first and that code works. Also since saving to desktop in IE lets me open the file, im assuming the problem has to be with the settings on the Response.BinaryWrite.
I have tried changing the buffer types, changing the content types to include "application/octet-stream", and tried using the extension/content type for office 2003 instead of 2007/2010...Here is my code

Using mStream As New MemoryStream Using spreadSheetDoc As SpreadsheetDocument = SpreadsheetDocument.Create(mStream, SpreadsheetDocumentType.Workbook) Dim workBPart As WorkbookPart = spreadSheetDoc.AddWorkbookPart Dim workSPart As WorksheetPart = workBPart.AddNewPart(Of WorksheetPart)()

I would like to use HTML input file type in my aspx page to allow user to browse for a excel file and then read the content of the excel sheet programmatically.If I want to read the excel sheet I need the full path of the file to connect to the excel sheet using asp.net.I do not understand how can I get the full path of the file.I know I can get the filename using postedFile.FileName property.But I need the full path of the file.
I would like to find a way to read a txt file (in my case delimited by ¤). I need to change the order of the columns and also add and remove some columns. My output file should be a txt file delmited by ;.
I tried Jet.OLEDB to read the file and put it into a datatable and then used a stringBuilder and streamwriter to get an output file in .txt format. However. This does not me since I´, reading the txt file from start to end and my output will be the same. It does not seem like I can have a custom sql statement when reading the file. The only query that works is
Dim da As New System.Data.OleDb.OleDbDataAdapter("Select * from 1.txt", TextConn)
i have stored the txt file to sql server database .
i need to read the txt file line by line to get the content in it.
my code :
[code]....

What did I miss ? is there a better way to get the database back home ?
