I am attempting to use the string.compare method in VB. One of the strings come off a list box that was converted over to a string(strLotto), and the other string (stringInput) is coming off of user inputted data. I am trying to compare the two and return the values that are the same into lstSameNums.
Public Sub UserData()
lstUserNums.Items.Clear()
Dim intNum As Integer

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Let's say I have a page Test.aspx along with test.aspx.vb.Test.aspx.vb contains a class name "TestClass". In that class I have method1(), method2() and method3()I need to be able to call one of those methods, but I can't hard code it, the method to be executed comes from a string.
I can't do
Select Case StringContainingTheNameOfTheDesiredMethod
Case "Method1"

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()
How can i compare two string values in vb.net? i've tried compare, equals functions but it's not giving me the correct result. what i'm trying to compare is as follows. also let me know if the code is correct. i'm new to vb.net

Here is my code for the string comparison function

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?
So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
String myTestValue = "NotModified";
TestMethod(myTestValue);
System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....
And what is going on under the hood? I would have bet my life that the value would have changed....
how do i compare 2 string variables to determine if they are the same?ie:
if(string1 = string2 AND string3= string 4) then
perform operation
else
perform another operation
end if
I'm trying to compare a string with all the items in a listbox, if it finds a match it returns true
Private Function Checkuser(ByVal username2 As String) As Boolean
If InvokeRequired Then
Invoke(New checkmeInvoker(AddressOf Checkuser), username2)
[Code]....
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. 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.

Edit : I get the this error at runtime.ArgumentOutOfRangeException Index and count must refer to a location within the string. Parameter name: sourceIndex
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.)

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.

View 3 RepliesFirst I create a class which have a string property
Property stdName() As String
Then I open a text file and put into array of that class
Dim arrStudent() As Students
Dim allstdinfo As New IO.StreamReader(dlgOpenStudentsFile.FileName)
Do Until (allstdinfo.Peek() = -1)
Dim strAllstdinfo As String = allstdinfo.ReadLine()

Finally I run a for loop and compare the stdName property with textbox.text
Dim counter As Integer = arrStudent.Length
(debug here)
For i As Integer = 0 To counter - 1
If (String.Compare(arrStudent(i).stdName, txtStdName.Text) = 0) Then

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 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.
I have two textbox in my application.
Textbox1.Text="19-Jan-2010"
Textbox2.Text="Jan 2010"
May I know how can I compare that Textbox1 and Textbox2 text is within same month and same year?

Overall what I am trying to get the function name as a string but without magic strings.
Assuming below.Public Class MyTestClass Public Sub Function1(ByVal junk as String) 'Doesnt matter what this does End Sub End Class So in another function in the same class, I want to do what you think something like Me.Function1.ToString() might do (but obviously doesnt work that way). Basically, I want the function names using intellisense, but as strings, not the actual call to a function.
