How can I import the data from my txt File to copy
Seems to me you have that backwards, don't you want to ask the user for the folder to save the file into (there is a directory dialog in winforms) and then save it to that path.
Never underestimate the power of human stupidity RAH
Hi Holmes, my txt file is well saved in my project and contains the data I want. The problem when the user saves it when he wants and then open it he founds: "System.IO.Streamwriter". This is my real problem. ty in advance (don't understand really u sentence :) :" Seems to me you have that backwards" )

He means give the user the choice of where to save it. Don't arbitrarily force a path on them that they don't want. Your path structure would be no good for me, for instance, because I like to partition my drives so the C drive contains the OS, the D drive contains my applications, and my E drive is my data drive - which automatically gets backed up onto servers (this is a lot simpler because of the partitioning).
I'm not a stalker, I just know things. Oh by the way, you're out of milk.

Hi Pete, U seem u don't understand my problem well. Me i save my file in a known path of my project (this is absolutely for me) that i write to u. Then I give the user the choice to save his file whatever he likes using this code:
StreamWriter report = (StreamWriter) GGetValue ("_Report");
string myPath = (string) this.GGetValue ("myPath");
this.BodyPage = "list.aspx";
string file_name = "test.txt";
string PresenceClientExtension = "txt";
//if ( report)
//{
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 = "application/octet-stream";
// Re-écrire le contenu.
this.Response.ContentEncoding = Encoding.GetEncoding ("windows-1252");
this.Response.Write (report.ToString());
this.Response.Flush ();
this.Response.End ();All works fine.the problem appears in the user side.when he save his file and open it he founds:"System.IO.Streamwriter" that is not the data that I have in the file on my project. this is my real problem. :) ty

Hi every body, I wanna generate a .txt file.I use the streamwriter to write my data to a file like this:
public static StreamWriter BuildTxtFichierVirement (ISReglementViewCollection reglements, ISISalarieCollection salaries, string myPath)
{
try
{
// Instanciation du StreamWriter avec passage du nom du fichier
StreamWriter monStreamWriter = new StreamWriter(myPath, true, System.Text.Encoding.ASCII);
foreach (ISReglementView reglement in reglements)
{
#region Date Virement ------------------------
string strYear = reglement.DateReglement.Year.ToString ();
string strMonth = "";
string strDay = "";
if (reglement.DateReglement.Month > 9)
strMonth = reglement.DateReglement.Month.ToString ();
else
strMonth = "0" + reglement.DateReglement.Month.ToString ();if (reglement.DateReglement.Day > 9) strDay = reglement.DateReglement.Day.ToString (); else strDay = "0" + reglement.DateReglement.Day.ToString (); string strDate = strDay + strMonth + (strYear.ToCharArray ()) \[strYear.Length - 1\]; string date = reglement.DateReglement.Year.ToString (); #endregion #region Entetes + EuroFranc ------------------ string strEnteteHead = "0302"; string strEnteteBody = "0602"; string strEnteteSum = "0802"; string strEuro = "E"; string strFranc = "F"; #endregion #region Données RIB -------------------------- string agence = "mdmff"; string guichet = "hhlkj"; string cle = "kjkj"; string compte = "lkjlkj" ; string domicilationbancaire = "ljkjol" ; #endregion //Ecriture du texte dans votre fichier monStreamWriter.WriteLine(strEnteteHead + Inserer\_Espaces(8) + agence + Inserer\_Espaces(7) + strDate + domicilationbancaire + reglement.ID + Inserer\_Espaces(15) + strEuro + Inserer\_Espaces(5) + guichet + compte + Inserer\_Espaces(47) + agence + Inserer\_Espaces(6)); monStreamWriter.WriteLine(strEnteteBody +Inserer\_Espaces(8) + agence + reglement.ID + reglement.Nom + reglement.Banque + Inserer\_Espaces(12) + agence + compte + reglement.Montant + agen -

Ah, I see what you are saying. The problem occurs because you are using the
ToString()method of StreamWriter when you doreport.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 byResponse.Writewhich 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 intoResponse.Writeinstead.I'm not a stalker, I just know things. Oh by the way, you're out of milk.

Sorry, but I don't understand this sentence, could you clarify?
I must get a clever new signature for 2011.
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().I'm not a stalker, I just know things. Oh by the way, you're out of milk.

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, somethingnew string(' ', N)does too. BTW: are you familiar withstring.PadLeft()andstring.PadRight()? :)Luc Pattyn [Forum Guidelines] [My Articles] Nil Volentibus Arduum

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

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).

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 ;)
