I need to create a code using String Compare() and Cases to figure out if a word, phrase, or what is typed in a textbox is a palindrome. If it is, a message will appear in a label under the textbox that reads, "What you typed is a palindrome." Or, "What you typed is not a palindrome." , if it is not.
View 16 RepliesI'm having a very difficult task here. I need to analyze a certain text and find the minimum number of characters it needs to become a palindrome. The text will not have any special characters or numbers, just alphabet letters. Now, I've made some progression and have tried a lot of situations correctly, but in some situations I've gotten wrong outputs on the MINIMUM number of characters needed. I've tested the below texts:
View 2 RepliesI need to create a a palindrome checker program. Now I know how to check a simple palindrome by using the reverse method however I am unsure if the palindrome had special characters or spaces. My question is what is the code for removing spaces and special characters from a string using loops and if statements. Also we cannot use arrays.

View 4 RepliesI am working on a project for the next week of my course and have the code built already and running but there was one section of it that looking at it I just dont understand why it works correctly.[code].....So i get that the second if statement here says that is palcheck1 = palcheck2 then its not the same telling the program its not a palindrome. But in the first part of it if palcheck1 is greater than palcheck 2 then it is a palindrome.
View 6 RepliesI am having problems getting this program to run. It is a palindrome checker, you are suposed to enter a word or a phrase and determine weather it is a palindrome. The code is suposed to contain a Boolean valued function, and should display true or false if word(s) are palindrome.
Here is my code
Private Sub btnAnswer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnevaluate.Click
Dim Input As String
If IsPalindrome(Input) Then
txtAnswer.Text = "True"

I'm working on a problem where i have to allow a user to input a word or phrase and then determine if it is a palindrome (a words that reads the same forwards and backwards) . It also says that the program should use a Boolean-valued function procedure named IsPalindrome that returns the value True when the word or phrase is a palindrome and the value False otherwise.

I have this string that shall come in from another file. The string has maximum length of 102 digits. I need to compare the string with numbers in a pair and delete those from that string.
e.g - 6125223659587412563265... till 102
numbers that compare with this string-
first set - 61
new string = 25223659587412563265
second set - 36
new string = 252259587412563265
and so on. the set of numbers shall go to maximum of 51 pairs = 102, which shall give an end result of string = "" How can i achieve this in a loop?
this is not answer, this is editing the question. i dont know why but the edit button just vaniashed so i have to edit question here. No duplicates will ever be in this string. and in the end when compares are done, i want to see what numbers are left in pairs.
i want to compare each character is string with the pattern and if any character matches it should give error.. eg, i have "ABCDEF" as patern to matched with.
and "OULJYSA" to be macthed with the patern, as u see A is common, so in that case it should display msgbox("match found") is there any way to do it? i did it in php using regex and preg_match()

My question is whenever I compare "alt+ctrl+w" with "alt+ctrl+W" it tells me that both the strings are the same, but as you can see that both of these strings are not equal because it got small 'w' and the other one is 'W', how come both of these strings are equal?

note ive tried more than string.compare does it have something with return false being at the bottom of the function. becuase ive tried adding an exit function once it returns true, but still I get returned with false to make it even more frustraiting the clipboard results are test/test
I am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.

I have a tblVersion that contains the versions of my application:
VersionID Version
VersionID is a bigint primary key, version is a ntext column that holds the current version... I want to be able to pick the row that has the highest version number, but version could be in this format:
MyApplication 1.0.1
If I try to convert that to a int32 it will throw an exception obviously. I would like to know if some of you have a idea how to solve this issue. I could of course make sure the column will only contain numeric values but this gives a little more flexibility.
for example i have two strings 0000 and 0001 then
0000
0001
----
result= 000- here difference is indicated by - sign
I am trying to make a program that will compare 2 documents. Idealy what this program would do would be to let the user define key words that he/she is looking for then hit the compare button and have those key words higlighted in both text documents. So far I have 2 button that paste stext into eather box and button that says compare this is my current code for the compare button
If tb1.Text = tb2.Text Then MsgBox("compatible!", MsgBoxStyle.Information) this works great but it only works if the text is exactly the same I just want it to pick up on words that are the same in eather box and eather A. show a message box that tells the words that are the same or better yet B. have them highlighted. I want to do this as simply as possible so if we have to leave out the key words thats ok. I am a big noob and don't know too much about VB (although I came up with that basic code myself thats about all I can do XD) so please bare with me.
I've read that it's unwise to use ToUpper and ToLower to perform case-insensitive string comparisons, but I see no alternative when it comes to LINQ-to-SQL. The ignoreCase and CompareOptions arguments of String.Compare are ignored by LINQ-to-SQL (if you're using a case-sensitive database, you get a case-sensitive comparison even if you ask for a case-insensitive comparison). Is ToLower or ToUpper the best option here? Is one better than the other? I thought I read somewhere that ToUpper was better, but I don't know if that applies here. (I'm doing a lot of code reviews and everyone is using ToLower.)

Dim stringParts() As String
Dim matches As Boolean = True

The I realized that it won't work properly. If I have ABCD as a normal and A*CD as my wildcard string the match will work even if my normal string was CDAB, which is not what I want.

I have a situation that I just can't seem to sort out in my head. What I have is a string that I would like to compare with another. Simple until I add the variable conditions to this task.
What I have is a string that looks like "t-EL" , "t-A" , "t-D" , "t-G" , "t-B" , or "t-EH" now the trouble both the strings could have characters leading these of following these. In every case there will be at lease One number after these ie "t-A0" or "t-A2" but could have a double digit number like "t-A13". Leading these strings could contain "!" or "#". In every case I'm only concerned with the character after the "-" but the trouble is some times I need to differentiate between the "EH" and "EL". I could find the location of the "-" and extract the next character and if it is "E" then the next two characters. Can we find a better way?
