I have this assignment that says: Create an application to let the user enter a sentence, then calculate how many words there are in that sentence. I know how to count the "Char" in a word (using .Length), but for this assignment, I really have no idea how to count the words in a sentence. What kind of method am I supposed to use for this particular assignment?

Can a LINQ or a LAMBDA expression be used to count the 1's in a binary string ?For example, if I convert a number to its BINARY using.>>
Dim binaryString As String = Convert.ToString( numberVariable, 2 )
1) Without using a loop such as a FOR NEXT loop, can I count the number of 1's in the STRING using LINQ or a LAMBDA expression?
2) Can I get the indexes of where the 1's are at in a collection such as a LIST using LINQ or a LAMBDA expression?I know the syntax of some LINQ expressions, however, I don't know which method may be suitable.
I want to count length of a userId and change the string to that many asterisks. I also want to take the account number and replace all characters except the last 4 XXXX.
View 2 RepliesI am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.
Here is what I have so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim strCity, strState, strZip As String
Dim strInput As String = txtInputData.Text
Dim intCount As Integer
'Obtain the count for city
intCount = strInput.Length
strCity = strInput.IndexOf(",")
lblCity.Text = strCity
End Sub
I would like to format output to a property of a custom control I have made.For instance I have a literal control in my control and when populated I want to check if it is longer than 30 characters long, if so, then go to the next space (as to not cut the word off) after the 30th character and place a <br /> tag in to place the next 30 characters on the next line.So if there were 100 characters in a string, there would be 3 line breaks in the label.I have the looping worked out to get the label populated but cannot get how to dymaically create the array based on the string lenth property and index of method.

View 5 RepliesI am trying to figure the best way to programmatically re-size table column headers in ReportViewer.Basically, my current resolution is the following: ColumnWidth = Header Caption_CharacterCount * 0.32...Where 0.32 is an estimated width of a typical character using my current font size.The issue is that the width leaves a lot of whitespace for longer captions.The more characters a caption has, the more whitespace I end up with.The issue with estimating this way is that not all characters are the same width. A good example would the the "I" character, which takes up less screen width than the rest of the alphabet.[code]

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
i have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data. Below is code I used to get the data when the Save button is clicked. [Code]
Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part. Plus even then I don't know if this would do what I want. EDIT: Ok I fixed the error and got it kind of working, but now I have a new question. Now, I put a button on the form that I can use to load the data when I choose to just to test. This works, it takes the data from each time slot and loads it back when I click the button. New question is how can I get it to load as soon as I open the existing appointment? Putting it in the form load event won't work because it checks for data before there is any in there.
This is what I have, but It doesn't work with strings for some reason (only text files):

My Ciphering program, Ciphers words from one text box to another one. A letter is put in front of each word to tell the length of the that word. Every character that gets entered into the text box will change the outputs text box. I am going to use HELLO as an example. The Number one, will represent the Original text, the number Two will represent the Ciphered text. [Code]
As you see, the first letter is the length of the word, as I said before. The other letters or gotten by getting the position of the letter in the alphabet and adding it with the length of the word. H H is the 8 letter in the alphabet, and so far, the length of the word is one. So you do 8 + 1 which is 8. AI That is where I got the I in this right here. HE H is the 8 letter in the alphabet, and now the word length is 2, so 8 + 2 = 10. The 10 letter in the alphabet is J, so the I in AI turns to J.
E is the 5 letter in the alphabet. 5 + 2 = 7. The 7 letter in the alphabet is G. That is where the G comes from. BJG The B is the second letter in the alphabet, and there is 2 letters in the word.
In order for me to keep track of each word, I store each word in a dictionary. That is the only method that I could get to work while using the word length character (The character in front of each word)
My big problem is if I want to backspace and go back for it to edit that word that it took a letter of.
My program know that there is a new word because when it recognizes that the selected character = " ", it creates a new add in the dictionary. Here is an example of 2 words that are ciphered.
HELLO THERE
EMJQQT EYMJWJ
I split it at the T to show you the 2 different words, and that the first word is ciphered the exact same as it was in the example at the top of the page.
Now I am pretty sure that I could get it to edit the most frequent word, but I know I would not be able to edit the past words because it seems that when I add something to the dictionary, it stays local as the variables, and not as new for its self. [Code]
That is not even close to exactly what the code looks like, but it is close I guess. Redundant, I know.What it does is for that word, each Letter is getting added to the Dictionary and is called by the number 1. So when H is typed, H gets added to item 1. When E is typed, item 1 is now HE, and so on for that whole word.
When a character = " ", a new dictionary is added but adding one to DicNum, and then repeating the process. What I have found out is that it will not keep the first dictionary, and come to think of it I only think that it keeps the most recent letter that was added to the dictionary.
The day that I was working on this I was searching for a while on how to use join, but found nothing. My question is, is there a better way or more efficient way to cipher each word and then edit the word that is being edited by backspace? Lets leave out the part where Dictionary1 and Dictionary2 or not need. [Code]
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.
While using the Socket.Receive method to receive messages through network, you should define a variable as the buffer and you have to specify the length like this: Code: Dim _ReadBuffer As Byte() = New Byte(LENGTH) {} My question is: What is the bad thing about increasing the length of this variable even if the received messages are sometimes shorter? (i.e. if some body let it 10000).
View 1 RepliesI'm trying to count syllables so I can calculate the Flesch Readability Index of some text that is inputted into a textbox. I can count words and sentences fine but my syllable count stays at 1 no matter what word I enter. A syllable is defined as follows:
Each group of adjacent vowels (a, e, i, o, u, y) counts as one syllable (for example, the "ea" in "real" contributes one syllable, but the "e..a" in "regal" counts as two syllables). However, an "e" at the end of a word doesn't count as a syllable. Also, each word has at least one syllable, even if the
previous rules give a count of 0.
