text-files

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have to change some connection strings in an incredibly old legacy application, and the programmers who made it thought it would be a great idea to plaster the entire app with connection strings all over the place. Visual Studio's "current project" search is incredible slow, and I don't trust Windows Search. So, what's the best free, non-indexed text search tool out there? All it should do is return a list

As a Christmas gift I have written a small program in Java to calculate primes. My intention was to leave it on all night, calculating the next prime and writing it to a .txt file. In the morning I would kill the program and take the .txt file to my friend for Christmas. Is there anything I should be worried about? Bear in mind that this is true beginner Ziggy you are talking to, not some smart error checking ASM guy. EDIT More specifically, since I will be leaving this program on all night counting primes, is there any chance at all that I will encounter some kind of memory related error?

What I'm doing right now is reading the contents of the text file and store it in a variable. After reading the whole content, I run a loop for the chunk data and in there call a function that will read to each line of the chunk data and pass every line to another function that process the processing of each column of data and inserting it in the database by batch. The batch is the whole chunk. The code process too long for every file with more than 500KB size. My problem is there is no unique identifier in the text file that I can use so that I can apply "LOAD DATA INFILE" which put me in

I have asked a related question in the past and I know how to read the file thanks to the help of the experts here. Now I have a new problem. I first read the data from the file like so: fid = fopen('D:\file.txt', 'rt'); a = textscan(fid, '%s %f %f %f %f %f %f', ... 'Delimiter',',', 'CollectOutput',1, 'HeaderLines',1); fclose(fid); I then process the file and change a few values of the column. Now I want to write a new file newfile.txt in the exact same format as my file.txt with the new values. How do I do that? If I do the following: M = [datenum(a{1}) a{2}]; dlmwrite('newfile1.txt', M); it

here is the code I am currently using to open a file using the openfiledialog ` private void openToolStripMenuItem_Click_1(object sender, System.EventArgs e) { //opens the openfiledialog and gives the title. openFileDialog1.Title = "openfile"; //only opens files from the computer that are text or richtext. openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"; //gets input from the openfiledialog. if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK) { //loads the file and puts the content in the richtextbox. System.IO.StreamReader sr = new System.IO

I have a text file that I'd like to import into R . Problem is, the file looks like this: x1,x2,x3,x4,x5,x6,x7,x8,x9,10,x11 1953.00 7.40000 159565. 16.6680 8883.00 47.2000 26.7000 16.8000 37.7000 29.7000 19.4000 1954.00 7.80000 162391. 17.0290 8685.00 46.5000 22.7000 18.0000 36.8000 29.7000 20.0000 and so on. I tried > data <- read.table("clipboard", header=TRUE) but that didn't work. While the data is ill-formed it still can be parsed given the following assumptions: The header defines how many variables there are (columns in the resultant table) The data itself is complete - e.g. there are

I need to read from a variety of different text files (I've some delimited files and some fixed width files). I've considered parsing the files line by line (slow using the File.ReadLine type methods) and reading the file using the ODBC text driver (faster) but does anyone have any other (better) suggestions? I'm using .NET/C#. I'm not sure you could really do a text-and-Excel file parser, not unless by Excel file you mean a comma/pipe/tab delimited file, which is actually just another text file. Reading actual excel files require you to use the MS Office libraries. For delimited text file

I am trying to get the following: [today's date]___[textfilename].txt from the following code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace ConsoleApplication29 { class Program { static void Main(string[] args) { WriteToFile(); } static void WriteToFile() { StreamWriter sw; sw = File.CreateText("c:\\testtext.txt"); sw.WriteLine("this is just a test"); sw.Close(); Console.WriteLine("File created successfully"); } } } I tried putting in DateTime.Now.ToString() but i cannot combine the strings. Can anybody help me? I want the
