Hi currently I'm working on a project and I'm wondering if anyone can help me, I have been set a task of creating a editor which I have done yes its basic and yes its from a book but I would like to add one more thing to it but I'm stuffed and cannot seem to get it to work.
basically I would like the output to be in hex rather than plain text, is this possible?
the code is
Code:
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;
using System.Drawing.Printing;
using System.Collections;
using System.Windows.Forms;
namespace Simple_ed
{
public partial class frmMain : Form
{
private string m_sfileName = "";
public frmMain()
{
InitializeComponent();
}
private void clearFormText()
{
this.Text = "Simple Editor - [unnamed]";
}
private void mnuFileExit_Click(object sender, System.EventArgs e)
{
// exit the application but query user if the text in the box has changed
if (rtfMain.Modified == true)
{
if (MessageBox.Show("Abandon all changes? - All data will be LOST", "Confirm exit",
MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
Application.Exit();
}
}
else
{
Application.Exit();
}
}
private void mnuFileNew_Click(object sender, EventArgs e)
{
// create new document with a check to see if the document has been altered
if (rtfMain.Modified == true)
{
if (MessageBox.Show("Create new document? - All unsaved work will be LOST?", "New Document",
MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
rtfMain.Clear();
m_sfileName = ""; // clear the file name
clearFormText(); // and reset the form caption
}
}
else
{
rtfMain.Clear();
m_sfileName = ""; // clear the file name
clearFormText(); // and reset the form caption
}
}
private void setFormText(string sFile)
{
// create an instance of a FileInfo class and use
// it to get the file's name without its path
System.IO.FileInfo fInfo;
fInfo = new System.IO.FileInfo(sFile);
this.Text = "Simple Editor - [" + fInfo.Name + "]";
}
private void mnuFileOpen_Click(object sender, EventArgs e)
{
bool bDoOpen = true;
// show an Open File dialog and open the file, but
// check that the current text has not changed first
if (rtfMain.Modified == true)
{
if (MessageBox.Show("Text has changed - really open another document?",
"Confirm file open", MessageBoxButtons.YesNo,
MessageBoxIcon.Question) == DialogResult.No)
bDoOpen = false;
}
if (bDoOpen == true)
{
// get a file to open and open it
dlgOpen.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
dlgOpen.FilterIndex = 1;
if (dlgOpen.ShowDialog() == DialogResult.OK && dlgOpen.FileName.Length > 0)
{
rtfMain.LoadFile(dlgOpen.FileName, RichTextBoxStreamType.PlainText);
rtfMain.Modified = false;
m_sfileName = dlgOpen.FileName;
setFormText(m_sfileName);
}
}
}
private void mnuFileSave_Click(object sender, EventArgs e)
{
// save the file if we have a filename for it
if (m_sfileName != "")
rtfMain.SaveFile(m_sfileName, RichTextBoxStreamType.PlainText);
else
mnuFileSaveAs_Click(sender, e);
}
private void saveFileDialog1_FileOk(object sender, CancelEventArgs e)
{
}
private void mnuFileSaveAs_Click(object sender, EventArgs e)
{
// if we have a filename, use that in the dialog, otherwise use
// a generic name
if (m_sfileName != "")
dlgSave.FileName = m_sfileName;
else
dlgSave.FileName = "SimpleEd1";
dlgSave.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
dlgSave.FilterIndex = 1;
dlgSave.DefaultExt = "txt";
if (dlgSave.ShowDialog() == DialogResult.OK && dlgSave.FileName.Length > 0)
{
rtfMain.SaveFile(dlgSave.FileName,
RichTextBoxStreamType.PlainText);
rtfMain.Modified = false;
m_sfileName = dlgSave.FileName;
setFormText(m_sfileName);
}
}
}
}
In my simplistic approach I am guessing that it is something to do with this line
Code:
rtfMain.LoadFile(dlgOpen.FileName, RichTextBoxStreamType.PlainText);
but as I have found learning this language nothing is as simple as it seems.
its just a starting point for me to learn really and i will be expanding it as much as i can as i learn ATM I'm just learning how to do the cut copy and paste.
I thank anyone in advance for the help they may offer
Sorry I forgot to say I'm using Microsoft visual studio 2010 c# if that makes a difference.
