I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

I am trying to automate the creation of an excel workbook from data retrieved from a SQL server. I have successfully automated the process and the file successfully saves in a pre-determined location as a 57kb xlsx file. However, when I run the Response.TransferFile code, a file is downloaded that is 18kb in size, and when you try to open the file, it says that the file has an invalid extension. Here is the relevent code:
[Code]....
I have tried multiple content types and different ways of specifying the content type (Response.ContentType = XXX, Response.ContentType = "application/excel","vnd.ms-excel",etc). Nothing works. I can't figure out why the filesize is different even if the extension is wrong.
I can navigate to H:/test/filename and open it just fine, so the excel portion of the code is working fine. I don't understand because this code is so simple yet goes so horribly wrong.

I have a download which is in a class below
[Code]....
and on my page i have a download button which runs a webhandler like below
[Code]....
when the download button is clicked it runs the code below
[Code]....
the dtresults is a datatable that is created on the page. the problem i have is if the cell has commas in like '12 london road, london, le126yr' in the database then its putting it onto the next line in the exported csv file and treating it as a carriage return rather than keeping all on the same line. I have done a replace in the code to replace the comma's to replace them with nothing but it doesnt seem to be working.

My goal is to create some Excel reports that users can download from my asp.net site. The data for the reports will come from an SQL database. I am using Visual Studio 2010 and the reports will be for Excel 2007.

User's need to "download" an excel sheet with data.
However this sheet need to be created on the fly (user's can check of which data they want exported).
From the user's point of view, it will just be a link "Download Now".
From coding point of view I will have an IList<MyClass> where MyClass say got members like EntryId, FirstName, LastName etc.
I do not want all fields to be dropped into the sheet (so I will need control over that in my code)
This sounds like what I'm after (since I'll always only have one sheet)
Create an HTML document and save it with a .xls extension - Excel will open it and treat it like a native Excel file. This method is very simple and, of course, free - however, it won't allow you to have more than one worksheet in the Excel workbook...

I'm using asp.net 1.1 to download data of a datagrid to excel file. I've used mso-number-format to display dates in short format 05/05/10 and numeric numbers with two decimal points. I want to set make text bold of some specific columns based on some business logic so that after download it boldness doesn't loose. So far I've tried with Css styling didn't get any result. I don't want to use .Net excel library: [URL] to do it.

I've a gridview which I am rendering to a html text writer and allowing clients to download as an excel spreadsheet using Response.Write. I'm using AJAX in my website now and suddenly it stopped working. This is the code I'm using
public static void Convert(DataSet ds, HttpResponse response)
{
try
{
//1. declare filename to export
string filename = "export";
//2. clear response object
response.Clear();
response.Charset = "";
//3. set response mime type to excel
response.ContentType = "application/vnd.ms-excel";
//4. prompt user to download the file
response.AppendHeader("content-disposition", "attachment; filename=" + filename + ".xls");
//5. create a string writer
StringWriter stringWrite = new StringWriter();
//6. create html writer which uses the string writer
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
//7. instantiate a gridview
GridView gv = new GridView();
//8. set gridview datasource to the dataset
gv.DataSource = ds.Tables[0];
//9. bind gridview
gv.DataBind();
//10. tell the gridview to render itself into htmltextwriter
gv.RenderControl(htmlWrite);
//11. output html
response.Write(stringWrite.ToString());
//12. end response
response.End();
}
catch (Exception ex)
{
string str = ex.Message;
}
}
I've found that Response.Write doesn't work with AJAX. Are there any alternatives to this?

I have created a CSV file on the server and want to send it to the user using the following code:
Dim strPhysicalPath As String
strPhysicalPath = Server.MapPath( "CSV/" & PathVirtual)
Dim objFileInfo As System.IO.FileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "attachment; filename=" & objFileInfo.Name)
Response.AddHeader("Content-Length", objFileInfo.Length.ToString())
Response.WriteFile(strPhysicalPath)
Response.Flush()
Response.End()
This seems to work fine except when the downloaded file is viewed in Excell the html code behind the page from which it came is also appended to the file. Does anyone have any idea why it does this?
