Streamwriter output

[Lost User]

You should use the SaveFileDialog class to allow the user to choose where to save the file. Here[^] is a link to a number of samples that may help you.

I must get a clever new signature for 2011.

Hi, I used it. It appears to the user if he wants to : -open file -save file -cancel after choosing open or save, the user founds in his file " System.IO.streamwriter" this is my difficulty ty

Ah, I see what you are saying. The problem occurs because you are using the ToString() method of StreamWriter when you do report.ToString();. This just writes out the name of the class. All you really need to do is write out a simple string value (that's what is being expected by Response.Write which is a stream writer in it's own right). Simply read the data you need and store it in a string (there are many suitable ways of doing this), and pass that into Response.Write instead.

Sorry, but I don't understand this sentence, could you clarify?

He's saying that the file contains the name of the class, not the output he's expecting - not surprising since he's used StreamWriter.ToString().

your code could be simplified quite a bit: 1. formatting numbers with specified width: use custom number formatting, so replace

if (reglement.DateReglement.Month > 9)
strMonth = reglement.DateReglement.Month.ToString ();
else
strMonth = "0" + reglement.DateReglement.Month.ToString ();

by

strMonth = reglement.DateReglement.Month.ToString ("D2");

2. getting last character of a number: use modulo 10, so replace

string strYear = reglement.DateReglement.Year.ToString ();
s=(strYear.ToCharArray ()) [strYear.Length - 1];

by

s=(reglement.DateReglement.Year%10).ToString();

3. FYI: If you were to require two-digit year numbers, the whole lot could collapse to a single line of code:

strDate=reglement.DateReglement.ToString("ddMMyy");

If interested, maybe read this[^]. 4. And I assume Inserer_Espaces(N) just returns the number of spaces specified, something new string(' ', N) does too. BTW: are you familiar with string.PadLeft() and string.PadRight()? :)

hi, when the user choose " open" or "save" icon (in the dialog appears to him),then he opens his file,it contains just "System.IO.Streamwriter" ty

Hi Luc, thank u a lot for the simplification of my code.I wanna know a solution for my problem :) ty

[Pete OHanlon]

I told you what the solution was. I just didn't write the code for you - that's up to you.

you already got the solution from others. overall suggestion: use fewer ToString() calls, they often are redundant, wasteful, and sometimes wrong. :)

Hi, Can u please explain to me more "(that's what is being expected by Response.Write which is a stream writer in it's own right). Simply read the data you need and store it in a string (there are many suitable ways of doing this), and pass that into Response.Write instead. I don't understand well u solution. ty

[Pierre besquent]

Hi, I found now the solution :laugh: . I use the streamreader like this:

StreamReader report = (StreamReader) GGetValue ("_Report");
string myPath = (string) this.GGetValue ("myPath");
string ligne = report.ReadLine ();
this.BodyPage = "list.aspx";
string file_name = "test.txt";
string PresenceClientExtension = "txt";
// Lecture de toutes les lignes et affichage de chacune sur la page
GRemoveValue ("_Report");
// Néttoyer le flux en cours.
this.Response.ClearHeaders ();
this.Response.Clear ();
// Re-écrire l'entête.
this.Response.AddHeader ("content-disposition", "attachment;filename=" + myPath);
this.Response.ContentType = "text/txt";
// Re-écrire le contenu.
this.Response.ContentEncoding = Encoding.GetEncoding ("windows-1252");
while (ligne != null)
{
this.Response.Write (ligne);
this.Response.Write("</br>");
this.Response.Flush ();
ligne = report.ReadLine();
}
this.Response.End ();
report.Close ();

All works fine now Thank u a lot for u all for u big help ;)
