I have a Label and a textbox that both contain strings. I want to compare the two strings like this:
If TextBox5.Text = Label18.Text Then
Label4.Text = "CLOSED"
Else
Label4.Text = "OPEN"
End If
Something in there is not working however. Has anyone done something similar?
I am attempting to compare a bitwise clone object to its parent to check for changes using:
If Not objCP.Equals(objCPClone) Then
'do something
End If
and it always compares as not equal even immediately after creating the clone. How should they be compared to check for changes?
I am having getting strings to match up if they are not in order in textbox1 [code]...
View 3 RepliesI am trying to compare 2 strings from 2 listbox's, sort of a fuzzy match then output the results in a treeview I'm trying to tell it to split the words where spaces appear such as "The Dog Went Up The Hill",So that would see that as 6 words and then compare that to listbox2 which may contain "the dog went up the hill last night" which would the return an 80% match,but i just can't get my head round this, here's my code.
Private Sub Compare_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Compare.Tick
If ListBox1.Items.Count = 0 Then

Is there a simple way to compare and combine two strings? Example:
String 1 = "The dog jumped over the fence"
String 2 = "The brown dog jumped"
A function or something that takes those two strings and returns: "The brown dog jumped over the fence"
I have 2 text boxes and I load a text file in to each box, the files contents are "almost" exactly the same but not 100%. how would i compare the 2 against eachother and output the difference in percentage? I've made a program once before it was pretty cool it did all these things and it was in VB.Net i just cant remember how i did it.. i do know i counted how many of the sames words exist but i cant remember what else i did.

I suspect there is something wrong in my application, specifically in a part where I have to compare a couple strings and a couple integers.
I do something like this:
If myString = myOtherString Then
do something
End If
And the same thing for integers.
However, for some reason, it is not returning true... also, I heard somewhere there were more proper ways to compare strings and integers.
how to compare values of two different strings.
View 2 Repliesis it possible to compare a string with substring of other case insensitively
I have tried it through string.compare() but i is case sensitive
if(details_local.Contains(details))
true only if the case matches else it is false
for example i have two strings 0000 and 0001 then
0000
0001
----
result= 000- here difference is indicated by - sign

When i save data in my xml file i save a bunch of cities that the user has selected, i then proceed to load the data back into the program and populate the check fields besides the city
vb.net
'// Loop through each one and re-check them
For Each cityToCheck As Xml.XmlNode In nodeList

This string stringSplit(0).tostring returns the city name say "Glasgow" i was trying to loop the listview that stores the cities, if they match then put a check mark, this is where the cities are located: (formAddCities.listViewCities.(FIRST ITEM IN COLUMN WHICH IS CITY NAME) the very first column in the listview, but i can't seem to get the right syntax?
I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False
ToolStripStatusLabel1.Image = My.Resources.pic_Add_Warning

As you can see this class get the .html text and copy to one .txt file. Then it reads the .txt file. Now I just need to compare the string it read with one string from another form... How do I do it? Do I need to change the code?
I am trying to write a program that will compare two strings in different text boxes. Then it must add 1 to a third text box for every time a letter appears in both text boxes. So for example if textbox1 said ABCDF and textbox 2 said ABTR it should return the number 2 because A and B appear in both.
This is what I have so far
Public Class Form1 Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles string1.TextChanged
End Sub
Private Sub Compare_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Compare.Click
Dim string1 As String
Dim string2 As String
Dim Result As Integer
End Sub
Function stringcompare(ByVal string1 As String, ByVal string2 As String, ByVal string3 As String) As Integer
stringcompare(string1 As string, string2 As string) End Function End Class
I have a Do loop that I want to exit once it goes through without making any changes to an object I created. I figured the best way to do this was to create a temporary copy of the object at the beginning of the loop and then compare that to the actual object at the end of the loop to determine whether any changes were made to it. The problem occurs when variables are accessed and copied by reference. I have tried to use some of the methods such as .Clone and .Equals (maybe I shouldn't be using these, but I didn't see any better built-in methods), but I seem to be doing some stuff wrong. Can somebody give me an example of a good way to copy an object for later equality testing, and how to do the equality testing?

View 2 RepliesI've got a heavily used web application that, for the first time in 2 years, failed doing an equality check on two doubles using the equality function a colleague said he'd also been using for years. The goal of the function I'm about to paste in here is to compare two double values to 4 digits of precision and return the comparison results. For the sake of illustration, my values are:
Dim double1 As Double = 0.14625000000000002 ' The result of a calculation
Dim double2 As Double = 0.14625 ' A value that was looked up in a DB
If I pass them into this function:
Public Shared Function AreEqual(ByVal double1 As Double, ByVal double2 As Double) As Boolean
Return (CType(double1 * 10000, Long) = CType(double2 * 10000, Long))
End Function
the comparison fails. After the multiplication and cast to Long, the comparison ends up being:
Return 1463 = 1462
I'm kind of answering my own question here, but I can see that double1 is within the precision of a double (17 digits) and the cast is working correctly. My first real question is: If I change the line above to the following, why does it work correctly (returns True)?
Return (CType(CType(double1, Decimal) * 10000, Long) = _
CType(CType(double2, Decimal) * 10000, Long))
Doesn't Decimal have even more precision, thus the cast to Long should still be 1463, and the comparison return False? I think I'm having a brain fart on this stuff...Secondly, if one were to change this function to make the comparison I'm looking for more accurate or less error prone, would you recommend changing it to something much simpler? For example:
Return (Math.Abs(double1 - double2) < 0.0001)
Would I be to try something like:
Return (double1.ToString("N5").Equals(double2.ToString("N5")))
How do you test multiple values for equality in one line?
Basically I want to do
if (val1 == val2 == val3 == ... valN)
but in VB.Net.
I have a method that takes an System.Action, this is what I'm trying to feed it:Function() Me._existingImports = Me.GetImportedAds()
The thing is that it complains about the = sign since it thinks I'm trying to do a comparison, which I'm not. I want to assign the Me._existingImports the value of Me.GetImportedAds(), but VB.NET complains about DataTable not having a = operator.
How can I force it to use the assignment operator instead of the equality operator?
In C# this works perfectly fine: () => this.existingImports = this.GetImportedAds()
For now the solution will be to use a standalone method, but that's way more code than needed.
I have two objects that are derived from same the base class. ets say ObjA is the base class, and ClassB and ClassC inherits ObjA. f I have a dim lst1 as List(Of ClassB) im list2 as List(Of ClassA)nd and I want to check for the existence of something being in lst1 that it is in list2, now I am only interested in comparing against one key bit of information that it is declared in the base class and is a string. How can I iterate through the lst1 comparing against list2? I thought I could I overload/override the Equals method but I am having no joy for either of the classes and say some thing similar to
Public Overloads Overrides Function Equals(ByVal obj As Object) As Boolean
Dim temp As ClassA = TryCast(obj, ClassA)
If temp.Id = Me.Id Then

I have several entities I need to make IEquatable(Of TEntity) respectively. I want them first to check equality between EntityId, then if both are zero, should check regarding to other properties, for example same contact names, same phone number etc. How is this done?
View 1 RepliesSo I'm writing the equality operator overload (Operator =())for a custom object, and the resulting mess of If conditionals is just an eyesore. But so far, it seems like the only sane way to check the values to as to match the specific behavior of this object.
The rules are:Num1 is required, period, and both the left and right operands and must be equal for True. Else, False.Num2 is optional, but if specified, must be present for both the left and right operands, and must be equal for True. Else, False.Num3 is optional, but can only be specified if Num2 is also present. Else, False.Num3, if specified, must be present for both the left and right operands, and must be equal for True. Else, False.

I also know that I could cache elements of the checks into booleans and then use those to reduce the amount of text. But that seems like a waste of cycles just for code readability. So I wanted to know if the SO community had better thoughts on reorganizing it, just in case I'm being too verbose with my checks.

View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
