I am a beginner. I have code to read in a text file, and part of how to get the strings into a text box. The format of the text file is like DREC: 04HF; and then the next begins with that same format. I need to read that from the text file and split it into 2 separate text boxes (3,4) at a : or a ; . Thank you for the help.

of.ShowDialog();
textBox1.Text = of.FileName;
}
private void button2_Click(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(textBox1.Text);
textBox2.Text = sr.ReadToEnd();
sr.Close();
}
private void button3_Click(object sender, EventArgs e)
{
int lcount;
string s;
int i;
lcount = textBox2.Lines.Length;
s = textBox2.Lines[0];
for (i = 0; i < lcount; i++)
{
textBox4.Text = textBox2.Lines[i];
}
textBox4.Text = s;
}
}
I need a better description of what you are doing but maybe this will help
//split apart segments
string[] split1 = textBox2.Text.Split(';');
foreach (string segment in split1)
{
//split sub-segment
string[] split2 = segment.Split(':');
//check if it's valid
if (split2.Count().Equals(2))
{
textBox3.Text += String.Format("{0}{1}", split2[0].Trim(), Environment.NewLine);
textBox4.Text += String.Format("{0}{1}", split2[1].Trim(), Environment.NewLine);
}
else
{
throw new ArgumentException("Invalid Segment");
}

Hey I want to create a windows application that should display the total lines, Blank lines and commented lines. I am able to calculate Total Lines, Can any one help me with the logic for blank lines and commented lines!
I want to count the Lines Of Code, for any file, i.e .html, .css, .cs, etc.
Also if possible I want the result to be exported to a Excel File!

I want more text boxes that should display count of blank lines, Commented lines, and finally the total count (i.e. subtracting the no. of blank lines and commented lines from total no of lines)
If Possible single button_click for each or all in one.enter image description here

This is my first question in Stackoverflow
I am trying to convert some files(.txt,.mp3,.mp4,.pdf,.png,.exe etc.) in a folder to a format .rjb, created by me. And I also want to recover the original files from the .rjb files. But every files other than .txt files get corrupted. Please help me, to accomplish this. The below code is what I am using.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Linq;
using System.Text;

namespace rjbformat
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
if (textBox1.Text != "")
{
try
{
//string data = Convert.ToString(File.ReadAllBytes(textBox1.Text));
// string datas = File.ReadAllText(textBox1.Text);
//string dat = File.ReadAllText(textBox1.Text, Encoding.ASCII);
//var dataS = Convert.ToString(datas);
using (StreamWriter sw = new StreamWriter(textBox1.Text + ".rjb"))
{
sw.Write(textBox3.Text);
}
}
catch (Exception)
{
MessageBox.Show("Specified Input file DOESNOT EXIST!", "Error", MessageBoxButtons.OK,
MessageBoxIcon.Error);
//throw;
}
}
else
{
MessageBox.Show("Please select Input file");
}
}
private void button2_Click(object sender, EventArgs e)
{
openFileDialog1.Title = "Open Text File (Rajib)";
openFileDialog1.Filter = "Text Files(*.txt;*.cod;*.ubc)|*.txt;*.cod;*.ubc";
openFileDialog1.Filter = "All Files(*.*)|*.*";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox1.Text = openFileDialog1.FileName;
textBox2.Text = openFileDialog1.FileName + ".rjb";
File.Copy(textBox1.Text, textBox2.Text,true);
FileAccess.ReadWrite.ToString(textBox1.Text);
var lines = File.ReadAllLines(textBox1.Text);
/* foreach (string line in lines)
{
textBox3.Text += line+"\r\n";
}*/
File.AppendAllLines(textBox2.Text, lines);
// FileStream fs = new FileStream(textBox1.Text, FileMode.Open);
// int hexIn;
// String hex = "";
// for (int i = 0; i<50/*(hexIn = fs.ReadByte()) != -1*/; i++)
// {
// hex = string.Format("{0:X2}", fs.ReadByte());
// // int bina = fs.ReadByte();
// textBox3.Text += hex;
//}
}
}
}
}
If all you are doing is storing one or more files into your .rjb format and want to get them back intact, this sounds a lot like creating archive files. In that case, you may want to consider just using a standard zip file and customize the extension.
Here's an example using the ZipArchive class:
using System.IO.Compression;
namespace CustomZip
{
class Program
{
static void Main(string[] args)
{
string startPath = #"c:\example\start";
string zipPath = #"c:\example\result.rjb";
string extractPath = #"c:\example\extract";
ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);
}
}
}
You will need to add a reference to System.IO.Compression.FileSystem to your project.
Im trying to make a program that replace a word in a file but i dont know how to replace when the word is now a unknown word
this is my code for replace when the file is unmodified, but when the user change the word/nickname and want to change it again, i need to know that word/nickname between 2 words
string path2 = filePath + "\\test\\versions\\"+comboBox1.Text+"\\";
string text = File.ReadAllText(path2+comboBox1.Text+".json");
text = text.Replace("${auth_player_name}", textBox1.Text);
File.WriteAllText(path2+comboBox1.Text+".json", text);
this is the 2 words between the word that i need to replace
--username ${auth_player_name} --version
now im trying to change the unknown word to ${auth_player_name} so the user can change it again, this need to be that word because my program can edit other files that are similar but with other name
i tried this but dont work
text = Regex.Replace(text, "--username \".*\" --ver", "-username \"${auth_player_name}\" --ver");
This is all the code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
using System.Text.RegularExpressions;
namespace ChangeName
{
public partial class Form1 : Form
{
string filePath = Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData);
public Form1()
{
InitializeComponent();
DirectoryInfo dinfo = new DirectoryInfo(filePath+"\\.minecraft\\versions");
FileInfo[] Files = dinfo.GetFiles("*.json", SearchOption.AllDirectories);
foreach (FileInfo folder in Files)
comboBox1.Items.Add(Path.GetFileNameWithoutExtension(folder.Name));
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
string path2 = filePath + "\\.minecraft\\versions\\"+comboBox1.Text+"\\";
string text = File.ReadAllText(path2+comboBox1.Text+".json");
text = text.Replace("${auth_player_name}", textBox1.Text);
File.WriteAllText(path2+comboBox1.Text+".json", text);
}
}
}
Regex.Replace Example
string path2 = filePath + "\\test\\versions\\"+comboBox1.Text+"\\";
string text = File.ReadAllText(path2+comboBox1.Text+".json");
//Changed to Regex
Regex reg = new Regex("--username ([^-]+)--version");
//using regex.replace function
text = reg.Replace(text, "--username " + textBox1.Text + " --version");
//end edit
File.WriteAllText(path2+comboBox1.Text+".json", text);
Documentation for Regex.Replace
Updated to set text variable equal to the replacement.

Ok, so you are using winforms and want to open multiple files? or a directory? and want to resize them. but there is nothing resized? or do I need more coffee? use http://nuget.org/packages/ImageResizer/ and I don't see a loop to loop over the files you want to resize.
Read more about the imageresizer component here: http://imageresizing.net/docs/managed
in your button1 click event, do something like this:
private void button1_Click(object sender, EventArgs e)
{
DialogResult dr = this.openFileDialogDosyaAc.ShowDialog();
if (dr == System.Windows.Forms.DialogResult.OK)
{
// Read the files
foreach (String file in openFileDialogDosyaAc.FileNames)
{
//resize and save
}
}
}
All of a sudden my form window has begun to close as soon as the application is launched. There's nothing in the output window that gives a hint as to what could be causing it and there are no errors thrown at me either. Does anybody have any ideas?
I've provided to form's class.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ProjectBoardManagement {
public partial class CreateBoard : Form {
Functions funcs = new Functions();
public CreateBoard() {
InitializeComponent();
}
private void CreateBoardButton_Click(object sender, EventArgs e) {
String BoardName = BoardNameText.Text;
String Pages = "";
String Labels = "";
foreach (ListViewItem i in PageNameList.Items) {
Pages = (Pages + i.Name.ToString() + ",");
}
foreach (ListViewItem i in LabelNameList.Items) {
Labels = (Labels + i.Name.ToString() + ",");
}
String BoardFile = ("board_" + BoardName + ".txt");
funcs.SaveSetting(BoardFile, "name", BoardName);
funcs.SaveSetting(BoardFile, "pages", Pages);
funcs.SaveSetting(BoardFile, "labels", Labels);
FormManagement.CreateBoard.Hide();
FormManagement.BoardList.LoadBoardList();
}
private void PageNameButtonAdd_Click(object sender, EventArgs e) {
String pagename = PageNameText.Text;
if (pagename != "") {
PageNameList.Items.Add(pagename);
}
PageNameText.Text = "";
}
private void LabelNameButtonAdd_Click(object sender, EventArgs e) {
String labelname = LabelNameText.Text;
if (labelname != "") {
LabelNameList.Items.Add(labelname);
}
LabelNameText.Text = "";
}
}
}
Obvious first thing to do - run it in Debug mode and stop execution on all exceptions. This should give you enough information on how to go from there.
Otherwise Functions funcs = new Functions(); looks suspicious.
