String Compare Function In VB?

Jul 4, 2011

Here is my code for the string comparison function

Public Function CmpKeys(ByVal oldkey As String, ByVal newKey As String) As Boolean
Dim cmpText As Integer

[code]....

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?

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.

Compare Letters Of A String To See If They Match

May 18, 2012

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.

Compare String Values From Database?

Jan 18, 2010

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.

.net - Case Insensitive String Compare In LINQ-to-SQL

May 8, 2009

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.)

Compare A Full String To One Containing Wildcard Characters?

May 16, 2012

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

[code]....

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.

String To Compare With Another - Until Add The Variable Conditions To Task

Oct 29, 2010

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?

I might have come up with something by just typing this up Check it out... Seems to be working for me

Dim p1 As Long
Dim p2 As Long
Dim s1 As String = StringName

String Concatenation String + Function Output + String = String + Function Output And No More?

The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"

This following code works correctly

m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag

What's going on here, what's the reason the first example isnt working and the second is?

The gvwSpots.LayoutToString() function returns a string.

Comparison - 4 String Lists - Compare The Contents Of The Input List - Containing Words

May 31, 2009

I have 4 string lists as follows

Dim input_list As New List(Of String) Dim input_POS As New List(Of String) Dim trigger_list As New List(Of String) Dim trigger_POS As New List(Of String)

I want to compare the contents of the input list (containing words (e.g., want, the) etc. to the ones of the trigger list (containign again words) and if a same entry (i.e. word) get the POS for both input word and trigger word from the relevant lists and put them into a property list. For example

input list (want, the, right)trigger list(want, there, wait)input list POS (verb, article, adjective)trigger list POS (verb, pronoun, verb)

Output property list (want:verb, want:verb) (only want is common between input and trigger list). Then I need to conduct a test between the two property items for similarites. If they are exactly the same, the code should output a confirmation "i.e., Yes" into a textbox. If not the code should output a "No" plus the contents of the property list into a textbox.
