C# - Best Approach To Write Huge Xml Data To File?
Apr 20, 2010I'm currently exporting a database table with huge data (100000+ records) into an xml file using XmlTextWriter class and I'm writing directly to a file on the physical drive.
_XmlTextWriterObject = new XmlTextWriter(_xmlFilePath, null);
While my code runs ok, my question is that is it the best approach? Or should I write the whole xml in memory stream first and then write the xml document in physical file from memory stream? And what are the effects on memory/ performance in both cases?
EDIT
I will indeed be using XmlTextWriter but I meant to say whether to pass a physical file path string to the XmlTextWriter constructor (or, as John suggested, to the XmlTextWriter.Create() method) or use stream based api. My current code looks like the following:

View 4 RepliesAJAX :: ModalPopupExtender Won't Hide After Response.Write With Excel
Aug 18, 2010I am having a great deal of difficulty getting a ModalPopupExtender to hide after I export a datatable to Excel.
If I simply rem out the Response.write in the code below, everything works correctly, but of course I don't get my excel sheet.
I have tried all kinds of ways to do this. Including calling a javascript function to hide it, wrapping the Panel in an updatePanel and placing the TransactionControl in a asp:PostBackTrigger.
All without affect. Anyone have a clue as to how to do this?
I was also hoping some event would fire after the ModalPopupExtender hides, but of course there is no such luck.

C# - Remove Password From Excel File -- Without Having To Install Excel On Servers?
Jan 12, 2010I need to remove the password protection from an uploaded excel file. I have been doing this directly with the Excel assemblies (ASP.NET/C#) and then I tried with the ooxmlcrypto, both worked, but the problem is that I can not deploy either of those solution because of the dependencies.
I mean, my sysadmin does not want us installing Excel on the server and, as I have been searching for some alternatives, I can not find one.
My question is: is there a way to put the necessary dlls in the server without installing Excel or the Office suite?
I found this: Office 2007 Primary Interop Assemblies redistributable package but still, it requires a Microsoft Office Product.

AJAX :: Allowing Clients To Download Excel Spreadsheet Using Response.Write?
Jun 24, 2010I'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?

Verbatim - Why Write @ Before Sql Queries - Select Data From Database Then Write Query?
Oct 1, 2010Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
