My file of words is too big to fit in my program. I have two columns for the Bad words, and Good words.

I just want to replace the bad words with the Good words. Please help!

Here is my dictionary file:

https://docs.google.com/document/d/1eTZaIUh7Q9zkNzjZQ-lPV9yxS5eSlNs5ht2-Pl-LS14/edit?usp=sharing[^]

Here is my code:

VB

Public Class Form1
    Friend WithEvents RichTextBox1 As New RichTextBox With {.Dock = DockStyle.Fill}
    Friend WithEvents ReplaceMenu As New ContextMenuStrip

    Private replacements As New Dictionary(Of String, IEnumerable(Of TextReplacement))
    Private nextCheckIndex As Integer

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Controls.Add(RichTextBox1)
        replacements.Add("a bad advice", {New TextReplacement("a bad suggestion", "Replace advice with suggestion."),
                                      New TextReplacement("some bad advice", "Replace a with some.")})
        replacements.Add("irregardless", {New TextReplacement("regardless", "Irregardless is not a word."),
                                      New TextReplacement("in spite", "Reword the phrase.")})
        RichTextBox1.Text = "You provided a bad advice, irregardless of your intention. You provided a bad advice, irregardless of your intention. "
    End Sub

Public Class TextReplacement
    Public Property Text As String
    Public Property Reason As String
    Public Sub New(replacementText As String, replacementReason As String)
        Text = replacementText
        Reason = replacementReason
    End Sub
End Class

What exactly is your question?

ZurdoDev 8-Dec-15 16:13pm

I fixed the pre tags so your code is visible now.

However, I'm still lost as to what your question is? It sounds like you are asking someone to read through all your code and make changes so it uses a dictionary object instead? You'll need to narrow down much better what you need help with.

I want to be able to use a dictionary instead of a preloaded list

ZurdoDev 9-Dec-15 7:02am

You have said that many times. That does not tell us where you are stuck or how we can help.

I want to use a dictionary file instead of a preloaded list. I have just edited the question.

ZurdoDev 9-Dec-15 7:23am

Again, you keep repeating yourself. We know that is what you want. So, since you won't give a specific answer does that mean you want someone to do all the code for you? That won't happen.

[no name] 9-Dec-15 7:38am

Please you could have just kept quite ok. I don't know why you have decided to answer or ask any questions.

ZurdoDev 9-Dec-15 7:42am

I asked questions because I want to help you. That's why we are all here. But I won't do all the work for you. Use the System.IO.File class to read in all the words in your dictionary and then go from there.

Sergey Alexandrovich Kryukov 8-Dec-15 16:06pm

All right, use Dictionary. What's the problem?

Here is a solution for you: don't ask "How to use a dictionary instead of a list", just ask "how to use a dictionary?" Only answering this second question makes sense, and it's way too easy: just read the MSDN documentation.

I did not want to disappoint you, but actually the ugly word "irregardless" is a valid English word.
Anyway, what problems do you have with your code? I cannot see any use of Dictionary...

I have a big wordlist, and I was trying to use a dictionary because the whole code is too big to fit in my program. You can press F8 to test it.

Matt T Heffron 8-Dec-15 19:16pm

Your replacements is a Dictionary.
You say "the whole code is too big to fit in my program". Do you mean that your whole set of TextReplacements is too much to implement directly in the source, so you want to read it all from a file into replacements?
Do you want to do the processing directly from the external file without ever loading it all into replacements?
You need to clarify exactly what you are trying to accomplish.

[no name] 9-Dec-15 7:05am

Yes! My file of words is too big, and has two columns for the Bad words, and the Good words. I just want to replace the bad words with the Good words. Just that!

Sergey Alexandrovich Kryukov 9-Dec-15 10:08am

Just use the dictionary. Just that.

I am trying to use a file instead of a preloaded list. How can I use a file instead of a preloaded list? I want to replace the bad words with the Good words.

Sergey Alexandrovich Kryukov 9-Dec-15 10:09am

It has nothing to do with the choice between list and dictionary.

I don't know how to indent the code here on his forum.

I have tried to edit the code but it can't show.

Sergey Alexandrovich Kryukov 8-Dec-15 21:39pm

Yes, it works now, but please click on "Improve question", look at the formatted code (probably by RyanDev) and learn how it should be formatted; it will help you to ask your next question.

This cromulent code should embiggen your knowledge.

C#

public class Replacement
{
    public string Word { get; set; }
    public List<string> Replacements { get; set; }
}

If you want to process the file without reading it all in memory then you can do something like this

C#

StreamReader sr = new StreamReader(@"c:\words.txt");

string word = string.Empty;
string lastWord = string.Empty;
string line = string.Empty;
char[] sep = new char[]{'|'};

Replacement r = null;

while ((line = sr.ReadLine()) != null)
{
    string[] values = line.Split(sep, StringSplitOptions.RemoveEmptyEntries);
    if (values.Length == 2)
    {
        lastWord = word;
        word = values[0];
        string replacement = values[1];

        if (word != lastWord)
        {
            Process(r);
            r = new Replacement();
            r.Replacements = new List<string>();
            r.Word = word;

            r.Replacements.Add(replacement);
        }
        else
        {
            r.Replacements.Add(replacement);
        }
    }
}

Process(r);

C#

public static void Process(Replacement replacement)
{
    if (replacement == null)
    {
        return;
    }

    Console.WriteLine("Possible replacements for {0}", replacement.Word);

    int i = 0;
    foreach(string r in replacement.Replacements)
    {
        Console.WriteLine("{0}: {1}", ++i, r);
    }
}

If you want to just create the dictionary from the file but keep the whole dictionary in memory then

C#

StreamReader sr = new StreamReader(@"c:\words.txt");

string word = string.Empty;
string lastWord = string.Empty;
string line = string.Empty;
char[] sep = new char[]{'|'};

Dictionary<string, Replacement> data = new Dictionary<string, Replacement>();

Replacement r = null;

while ((line = sr.ReadLine()) != null)
{
    string[] values = line.Split(sep, StringSplitOptions.RemoveEmptyEntries);
    if (values.Length == 2)
    {
        lastWord = word;
        word = values[0];
        string replacement = values[1];

        if (word != lastWord)
        {
            if (r != null)
            {
                data.Add(r.Word, r);
            }
            r = new Replacement();
            r.Replacements = new List<string>();
            r.Word = word;

            r.Replacements.Add(replacement);
        }
        else
        {
            r.Replacements.Add(replacement);
        }
    }
}

data.Add(r.Word, r);

foreach (string key in data.Keys)
{
    Process(data[key]);
}

How can I use a dictionary please?
