StreamWriter - Last Line Of File Is Always Missing A Few Characters
Aug 19, 2014
I'm using a streamwriter to write a tab delimited file (for import into Mail Chimp), but the last line of the file is always missing a few characters. Doesn't matter what size the List<t> is (its small - about 128 lines)
I've looked at the last item of the List in the debugger and it's just like all the rest. On write, its always cutting off the last characters - which happen to be '.com'. Kinda important. Some posts say to flush and close - tried it. No change. Last characters still AWOL.
Currently I have the text file going to desktop, in ASP how can I prompt a file save dialog for the user? The result is string from the streamreader as "result" as follows:
StreamWriter FileWriter = new StreamWriter(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "file.txt")); FileWriter.Write(result); FileWriter.Close();
i have been trying to solve this for hours with no luck. i seem to be missing something fundamental.
i have a remote FTP server with a file called log.txt on it, i wish to allow web users to download this file to their local drive to a designated folder.
i have a function calling this sub i found on the web with the filename to download.when trying to run this code i get this error:
" Could not find a part of the path 'C: empFtpDownloadsFolderlog.txt'. "
[Code]....
if i replace this line:
[Code]....
i get no error but the file is not in the TempPath. (it shows it to be saved to "C:WindowsTEMPlog.txt" )
i have a feeling its being save on the server instead of my local drive.
I have sepatare my web page into 2 parts through divs; the left hand portion and the right hand side.The left hand side div gets the project names from a database. As the width of the left hand side is very small I need to limit the number of characters in the project name to 20 per line.
Eg: Assume the limit was 5 and I have a project name "project 123456" I need it to be displayed as
I am using Multi-line Textbox through which users will be able to enter data which will be saved on to the SQL Server 2008 database. There is an other process, which reads this data from the table and writes to a text file.
Problem:
If the data entered by users in text box contains <Enter> from keyboard, it is saving to the database with some spaces replacing the <Enter>.
Some how if I read the same data to a text box on webpage, it is being displayed properly.
But, if my second process that reads the data from database and prints to a text file, it is not keeping the text format properly. It is not retaining the <Enter> in the data being printed to text file.
1) Is it possible, in a multiline textbox, to automatically break to the next line after 100 characters? 2) If not, is it possible to parse the enter key as entered by the user to break the line in the code behind?
Some additional info:
The person requesting this does not think that the user should use a single line textbox limited to 100 characters and click an "Add Line" button to store that field in a table.
The person requesting this is of the belief that a DEC Alpha-based system that currently does this can be replicated on the web.
how to limit the number of characters per line in a multiline textbox? Any posibility to do this with javascript? I have the users enter a list of names and need to limit each. I hate to use another textbox to add each name. If so, I would then add them to a listbox instead so they could select and remove a name.
I wrote a small .NET applications that removes all line breaks in aspx/html/css code to make it harder to read for people trying to steal my design. And surprisingly I get weird characters that appear out of nowhere such as Â, » and others. They all stay at the same places, but I have no clue why they appear.
In my text area, I should be able to enter only 72 characters per line. If I use, cols property set to 72, it is allowing more or less number of characters depending on character width.
I m uploading a file and I want to read that file line by line. I have 200 users accessing that application at one time and I have more than 300 lines in a text file to read. If I do it in a normal code, it may crash. So, what are the ways to do this application? Web services or COM+. which is the better way? I dont want my application to crash at any point.
i get the following exception (missing primary key) in the line of using Find() method "Table doesn't have a primary key." I've rechecked the Database and all Primary Key columns are set correctly.
DataTable dt = p.GetAllPhotos(int.Parse(Id)); DataTable temp = new DataTable(); temp = dt.Clone(); temp = (DataTable)(Session["currentImage"]); DataTable dtvalid = new DataTable(); dtvalid = dt.Clone(); DataRow[] drr = new DataRow[1]; drr[0] = dt.Rows.Find((int.Parse(temp.Rows[0]["photoId"].ToString()))+1); foreach (DataRow dr in drr) { dtvalid.ImportRow(dr); } dtvalid.AcceptChanges();'
I'm using the file upload control to enable users to browse to a document, and then upload it. But, I've run into a problem. Some users include a # sign in the file name... Something like "file#123.pdf" The file uploads ok, but, when another user trys to open the uploaded document from the gridview, it errors. If I manually rename the file and remove the # symbol, the file will open ok. How do I prevent users from uploading a file with a # sign in it, or how do I strip out that symbol?
I am writing to a CSV that will contain different customer information. Right now when I write to it, it overwrites whatever is in the path right now. Instead of overwriting I would like the new writer.WriteLine to append to the current CSV without overwriting it.
Code
[Code]....
Also, can anyone help me with writing the file to a different location other than my local project file? I need the path to become a server location instead of the CSV folder stored locally.
i'm using stream writer to write a text file on client machine, but everytime while i'm writing a new file it over writes the existing one..so now i need to write seperate file each time ...and also i need to create a folder dynamically for first time and save text files in that folder when everytime i use my application....
I have myConnectionString and it's working fine. In the Server Explorer, the Data Connection is even using myConnectionString to connect to the database. When I created my .dbml, it uses that same yConnectionString. However, now whenever I opened the .dbml file, pops up with the following message:The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place.After this message is display and I clicked okay (because that's the only option), it creates myConnectionString2 in the web.config file with a different ID but no password provided. What is this all about? Why is it creating a second connection string with a different ID?

I am generating a pdf file in asp.net c# using itextsharp. i am not able to draw a horizontal line/verticle line/dotted line.
i tried to draw a line using the following code,i am getting no errors but the line is also not getting displayed in the pdf file
PdfContentByte cb = wri.DirectContent; cb.SetLineWidth(2.0f); // Make a bit thicker than 1.0 default cb.MoveTo(20, pdfDocument.Top - 40f); cb.LineTo(400, pdfDocument.Top - 40f); cb.Stroke();
What is the problem in the code.Is it because of the position of x y co-ordinates? I had used rough points to know approximate position in pdf,but the line never apears in the pdf file.
The output i am looking out for is as shown in image below.
