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()
The following code will detect one character and replace one charater
if have 2 character AE , NR, TE, which combines as AENRTE, am trying to edit the code,
input AENRTE = abc

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

View 2 RepliesI am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

View 2 RepliesI've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...

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.

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 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.

View 7 RepliesI'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.)

I have a method that takes 2 string arguments. One that contains a normal string and one that contains a string with one or more wildcard characters. I've tried the following code:
Private Function DoesMatchWildcardString(ByVal fullString As String, ByVal wildcardString As String) As Boolean
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?
