How do I read/write a text file on another server from a web page.I get the error "Access to the path '//Server2/mydatafiles/test.txt' is denied". I do not get the error if I am running the browser on the server where the files exist.I think I need to set permissions on the destination server in some way.

Is it possible to read .pdf as above.
I have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.
I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.
I know that by reading out the text file row by row it will be certainly slow.
how to read out the text file fast and also how to do the file processing for the read out text file?
I want to read and write a txt file but
The process cannot access the file 'D:BelgelerimVisual Studio 2005WebSitesmacrotechCounter.txt' because it is being used by another process.
what is wrong with this
StreamWriter FileWriter;
StreamReader FileReader;
string Countstr;
string str1;
int Len1,i;
FileReader = File.OpenText(Server.MapPath(Page.ResolveUrl("~/Counter.txt")));
FileReader = File.OpenText(Server.MapPath("~/Counter.txt"));
Countstr = FileReader.ReadLine();
FileReader.Close();
FileReader.Dispose();
i = Convert.ToInt32(Countstr) + 1;
Countstr = Convert.ToString(i);
FileWriter = File.CreateText(Server.MapPath("~/Counter.txt"));
FileWriter.WriteLine(Countstr);
FileWriter.Close();
I found some code that looks like it will do what I want to do, but the code doesn't work.
[Code]....
The error seems to occur here: mytext.txt
Error Message is: unrecognized escape sequence
I think somehow the syntax with StreamReader is not quite right.
I did something similar in VB and it worked fine. I'm just beginning to learn C#; it's going to be a little while before the training wheels come off.

How to read a text file and saved in data base
View 1 RepliesI have a txt file, in which read only property is true. When I try to write some text in that file through the vb coding, it's through the error. I have shown the code below.
Dim fs As FileStream = File.OpenWrite(HttpContext.Current.Server.MapPath("Include/CacheKeyFile.txt"))
Dim sw As New StreamWriter(fs)
sw.Write("Menu setup updated by " & value & " on " & DateTime.Now.ToString())
sw.Close()
fs.Close()
I found the cause of the error. If we set the Write access property to false, we can open the file and write it without showing the error messages.
I need to remove the Read only property for a file through the vb. Net code. Is it possible? Can we set the read only for txt file before open and write operation?
I want to read a text file and separate the data and write it back to another text file. So the input file content is like 07090000079011110225000 00001000100010118832 032111050111205011110501111022500000FL .... I know that first 3 characters are for CompanyID, next 2 are for Symbol etc. How Can I put it together? I used to write in VB code like this below using a Type and define the width there.(easy to maintain) How can I do that in VB.Net or c#?
[Code]....
So the output will be like CompanyID : 070 Symbol :90 .

View 7 RepliesCurrently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

I am trying to open .dbf file from the server for which I have written below code.
Now, the problem is connection string accepts only physical path from the client machine where as I want it to pick file from the server.

oConn.ConnectionString = @"Driver={Microsoft dBase Driver (*.dbf)};SourceType=DBF;SourceDB= http://localhost:1308/CNCScheduling/...;Exclusive=No; Collate=Machine;NULL=NO;DELETED=NO;BACKGROUNDFETCH=NO;";
oConn.Open();
System.Data.Odbc.OdbcCommand oCmd = oConn.CreateCommand();
string sPathApp = Request.ApplicationPath.ToString() + "/";
string sPathFull = Request.Url.OriginalString.ToString();
int iPathFullLen = sPathFull.ToUpper().IndexOf(sPathApp.ToUpper());
string sPathPrefix = sPathFull.Substring(0, iPathFullLen) + sPathApp;
string sRPTFile = "XABCL.DBF";
string sCrvPage = "D:\databases\" + sRPTFile;
oCmd.CommandText = @"SELECT * FROM " + sCrvPage ;
DataTable dt = new DataTable();
dt.Load(oCmd.ExecuteReader());

View 2 Repliesfiletoread = Server.MapPath("\servernamesharefile.csv")
filestream = File.OpenText(filetoread)
readcontents = filestream.ReadToEnd()
It works fine if I put the file in the local directory and use "filetoread = Server.MapPath("file.csv")", but won't do it over the UNC path.I'm guessing the problem is security related but can't find any info related to it, do I need to somehow specify a username/password somewhere ?
I would like to know your libraries recommendations to read and write Excel applications on ASP .NET website. I have tried GemBox and NPOI, because they don't required Excel to be installed on the server, but they have some limitations on handling Excel files that are marked to read only.

I have an input type, so a text box which has a browse button next to it. When it is clicked, the file that is selected has it's full path placed into the text box.
<input type="file" runat="server" id="txtFilename" style="width:400px" />
Where is the event! Now that I have the path to the file in the textbox of the input type, I want to load each line of this file into a textbox that is able to handle multiline text. I don't want the file to be uploaded to the website. I just want to contents of the file read and placed in a textbox all with one click on the browse button.
I have a problem that I have been trying to solve the past two days, but I cannot figure it out...I have a folder which will have 60-70 Excel Files or CSV Files (they are right now). There are no headers in them, but they all have the same # of columns and the columns are in the same order in each fileI need to read each file in the folder, grab the data from the file and put it in a Database file. So all files will be read and then the data from them I guess put in a DataSet and then put into a Database (SQL).
View 3 RepliesI have a function that will take a file uploaded by a user of my system and store the contents of the file into a varbinary(max) field in a sql server database. I then display the filename of the file in a data grid for the user to see as a link button. When the user clicks on the link button, I want the file to be read from the database and served out to the user as a prompt to download the file. How can this be accomplished? The upload is fine, it is the download I can't figure out. Here is what I have so far.

I get the download to prompt, but it is showing the name of my .aspx page as the file to be downloaded.
