i have a small problem implementing text spinning in vb.net. Text spinning is an art of changing text by replacing some words by their synonyms.

like : codeproject is an excellent website.

spin syntax : codeproject is a {excellent|good|cool} website

so everytime we spin, we get sentences like :

codeproject is a good website
codeproject is a cool website etc.

i have a list of synonyms from a dictionary (text file). how do i implement the above syntax in vb.net and how do i spin

suppose the user selects the word in a rich textbox and clicks a button, then the word should change to

{original|synonym1|synonym2|synonym3}

next when the user clicks spin button, the changed text should appear in another text box, but how do i select the word from above options??

i do not want the whole code, only some ideas??

Hi, the dictionary you say, is kind of a xml file? it should be, isn't?

and use a rich textbox isn't the best way. Why don't you limit the words that user can select in a Select tag (or asp.net DropDownList)

if you do like this, you can generate certain code in the page, that makes the suggests (or spinning) in different labels with dropdownlist SelectedIndexChanged. And add a <a> tag or an that select the text and pass it through javascript to the textBox.

Understand me? ;)

its a windows application not a web application, that is why i need to do it in a richtextbox

Then use a key_Up event of RichTextBox and evaluate every word. Then dynamically generate rows in a selectable grid view

What exactly are you stuck on? Really, that wouldn't be that difficult to do.

Personally, I would do it through a ContextMenuStrip, but you can do it the way you want.

It's easy enough to get and change the selected text within a RTB. All you do is read and change the SelectedText property.

Then, you could set up a series of CharacterRanges that are associated with each of the new synonyms. Then, when the user mouses over any of the CharacterRanges, change the mouse to the Hand. Then, if the user clicks while over one of the CharacterRanges, you change the previous word to the new one.

Of course, there are some things to think about. Like what if the user starts typing and now the CharacterRanges are off. Well, you'd have to know if you had added any and then hook the TextChanged event and find the new ranges and update them. But, there are definitely many ways you could to it to find them. Personally, I would have a class to store all of that information and it could create the string with the {original|synonym1|synonym2|synonym3} set up and then you could use it to search for your string. The class could also store the CharacterRanges for checking mouse position or just tell you if you're over a CharacterRange and which one you're over.

I would also look into using NHunspell. It's a stand-alone spell checker, but it includes a thesaurus. It's extremely fast at generating synonyms and does all of the work for you.
