Compare Textbox Text To Strings In List?
Jun 10, 2009
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
ToolStripStatusLabel1.ForeColor = Color.Red
[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

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

First 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()
Dim arrStudentLine() As String
[Code] .....
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
lblPhoneNo.Text = arrStudent(i).phoneNo
End If
Next
And I add watch:
Why the compare return 1

Again a little (for me) tricky thing:Supose you have a ComboBox control with predefined values - to keep it simple, let's add some colors:
- Blue
- Green
- Red
- Yellow
Now you have a TextBox control as well. If you type into the TextBox BLUE (non-key sensitive) I would like to make it recognize that this value already exists. It does not have to do anything else except for notifying me about a match.I do think that the TextBox1.KeyPress or TextBox1.TextChanged event is what I need but I have no idea how to compare to the ComboBox1 items. I've tried to create an Array of my ComboBox1.Items but didn't get much more than errors. Can anybody help? I am sure it is quite simple however, I can't get my mind set to go in the right direction

I have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...
*Also if it is possible I would really like to have a check box list that contains the data from the "Device" columns so I could check the "Device" and then it search the TextBox.Text for the checked "Device's" "MCaddRG"

I 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.

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?

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
[code]....
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'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

I 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))
[code].....
It works, but I would rather use built in functions whenever possible.

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
