Usage of System.IO.MemoryStream as a UserDictionary source - RapidSpell Web ASP.NET - Forum

Hi, if you write a subclass like that in this example https://keyoti.com/kb/De...uestId=128&catId=55 you won't have to specify a filepath, and can load/save it to your stream. I'm assuming you will be writing to the stream when the Add button is clicked.

Hi Jim,

Some time ago I asked you about usage of memoryStream as a user dictionary source and you advised to inherit UserDictionary class and do processing of MemoryStream storage in it.

I implemented such inheritor, but for some reason after I have applied a new version of Spell check (5.3) (it might be not related to the issue, but the code was not changed), an unexpected behavior appeared.

I am filling wordList variable of my child class that inherits UserDictionary with three words from file:

JSmith
IGoblet
jblack

and I can see that when I set my inheritor as a user dictionary it already includes the mentioned words (without any unexpected characters) in it. (I am doing that with SetUserDictionary() method of Keyoti.RapidSpell.RapidSpellChecker class).

Additionally, I am enabling flag SetIncludeUserDictionaryInSuggestions to have the words as proposals.

After that I am trying to check the following string:

"IGoblet and JSmith jblack and Jblack"

In this case, I am getting results that the word "JSmith" is an error, but at the same time, I have absolutely the same word as a proposal for this error.

If I have only "JSmith" word in user dictionary, the string is checked correctly.

The question is: is it enough to add the words to wordList list or I need to do something else at the moment to make it work? You might have some thoughts on that and if you do, please, share those with me.

A piece of code that is used to load words from stream attached below:

using System;
using System.Text;
using System.Collections;
using System.IO;
using Keyoti.RapidSpell;

namespace CustomKeyoti
{
public class CustomUserDictionary : UserDictionary
{
ArrayList wordList;
MemoryStream stream;

protected void loadWordsFromStream()
{
wordList = new ArrayList();

var reader = new StreamReader(this.stream);

for (string line = reader.ReadLine(); line != null; line = reader.ReadLine())
{
wordList.Add(line);
}
}

public CustomUserDictionary(MemoryStream stream)
{
// Read words from stream to arraylist
if (stream == null)
{
throw new ArgumentException("Parameter cannot be null", "stream");
}

this.stream = stream;

this.loadWordsFromStream();
}

... // code for adding / removing words etc.

}

Thanks in advance.

Thank you very much for the response.

The code of ReadAll method:

public override int ReadAll(ArrayList a)
{
a.Clear();

a.AddRange(wordList);

return a.Count;
}

The previous version we used was 3.8.

I would be grateful for that. Thanks in advance.

Hi Jim,

Your solution works in my case.

Thank you very much!
