I am trying to generate a combination of string words and this is not permutations. For example if I had a list of words like (bat, cat, dog, egg...)then try and generate n(n-1)/2 combinations like
bat cat dog egg
batcat catdog dogegg
batcatdog catdogegg

I need to generate all combinations (not permutations) in VB .NET, I've been search and all I found is for permutations (some says combinations but when I was try it, all are permutations).
What I need is to generate combinations from string array:
Dim data_array As String() = {"one", "two", "three", "four", "five", "six"}
I need that: If I say just 1 length, it must returns:
one
two
three
four
five
six
If I say 2 length, it must returns:
oneone
onetwo
onethree
onefour
... etc ...
twoone
twotwo
twothree
... etc ...
And continues til end with all combinations. If I say more length do it as well.
I'm trying to write a function to find a word in a string in the this format : "ThisissometextthatIneedtofindandthisisthetext. This is another text."It's read as " This is some text that I need to find and this is the text. This is another text." but there is no space between each word. I want to get the word "text" or any word in that string. Can you help me with this function with a code sample ?
And I think that this method can be implemented with a string of Unicode also because in a sentence of Unicode it contains one or few, sometimes zero spaces between each word.
I have a string and I want to see if inside that string I have the word Peter.

This does not work, It still says Yes when I have Not in the textbox. How can I do this correctly?
Is there any function or collection in VB.NET that checks if a string is a word? Like a dictionary?I'm making a random word generator, and I can get it to generate random strings, but it's be better if they were actual English words..I know something like System.Collections.Generic.Dictionary would work, but wouldn't you first have to add all of the words into the Dictionary?I guess what I'm looking for is a Collections.Generic.Dictionary with English words preloaded into it?

I am trying to create a function that searches each line of a richtextbox and returns that row if one of many search phrases are found.The app works wonderfully when used with longer words or muli word phrases as the search criteria.The problem I have is if the search word/ criteria contains a small string such as bae or sp then I get alot of false positives. Anytime bae or sp is found within any word it returns the results.I need the function to stop looking within the words for results and instead look at the word as a whole for a match.Below you can see that I am taking each line of text in the richtextbox, removing most non-alpha numberic characters and replacing them with spaces.Then I have it remove any double spaces with single spaces.For the search term list I have it take the text before the delimiter;and do the same.Trouble I am having is,if the search term is SP and the search phrase is "This is a space shuttle lauch"it will return the sentence since the sentence contains the word "space" which starts with sp.[code]
View 8 RepliesProblem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
VS 2008 08/10 counting vowels in each word,longest/shortest word?
View 8 RepliesThe following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.
1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.
2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.
However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?

I want simply to generate rapidly combinations of 16 take by2 using linq.So I want to display me the combinations only not arrangements:1,2 (not 2,1 because there are combinations)...1,16 2,3 (not 3,2) because they are combinations..2,16..Comb of 16 take by 2 makes 120 so 120 combinations will be displayed on screen.[code]So my question is how to display rapidly on screen the combinations of 16 take by 2 using this Enumerable class of Visual Basic .NET(the 120combinations in fact)

I think what I'm trying to do is considered a permutation but I could be wrong. I've come across several examples of how to permutate a string as follows:
Permutations of {A B C}: {A B C}, {A C B}, {B A C}, {B C A}, {C A B}, {C B A}
What I'm needing are results similar to this (using the same input) with a repeat of each item to create a list of all possible combinations: {A A A}, {A A B}, {A A C}, {A B A}, {A B B}, {A B C}, {A C A}, {A C B}, {A C C}...and so on.
Below is some code that I found that almost gets me there with an exception of the repeated values:
'Generates all possible combinations from a series of words

If i had a fixed number of Size types i would just run For loops within for loops and inside the inner most for loop write an Add Item statement with Index of evry selected item, however since the Size types are dynamic, i need to write a recursive loop, and i just cant figure how to.

I've got this problem where I'm supposed to be determining whether a string is a word or not. not exactly.Its supposed to just make sure each string has at least 1 vowel, and each vowel is surrounded by consonants. If it meets those requirements it'll be accepted, if not it'll be rejected, but I've already got that part figured out. I think I know a horrible way to do it, that would take a very long time, but I'm thinking there has to be a much easier way..

I am receiving data from other computer over tcp/ip and the received type is below...
"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID

In the above string, i want to get only BOLD string value.
Sometime the data would be "Info,Reply:Timestamp 75ff, SpecificID c07c343a" and
sometimes it would be many repeated value like
"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID

When i enter the word "testing" in textbox and click on search then it is highlighting the word "testing". but when i enter "is testing" in textbox and click on search then it is not highlighting the word "is testing". this is due to there is bold tag for "testing".
How can we highlight the word which is in bold tag...
