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
[[Code].....
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?
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
[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'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

vb
Imports System.IOImports System.NetImports System.Text Public Class TEST Public Shared DOWNLOAD_LINK As String Public Shared Downuri As String Public Shared Sub Main() Dim URI As String URI = "http://MYWEBSITE.COM/test.html" Dim wr As
[code]....
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
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?

View 5 RepliesI've came to the stage where i need to save strings and application settings for my application. The My.Settings have worked it out until now. Now i have to store so many settings it's hard to keep track of them. That is why i need something new. So i've been looking around in INI files which seems impressively simple - but not very flexible. I've also took a look at XML which seems to be something to dive in to. But what i need now is advice. How do you store settings?
View 11 RepliesI need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this:
Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String

Dim randomString As New StringBuilder

What is going on? I thought that I used to, a long time ago, be able to just do random.Next.
I am using VB 2008 & MS Access 2007 Databases for my Windows Forms Applications.The Problem is my Connection strings have been disappeared from DataSource Configuration Wizards & now i am unable to edit any Connection String in DataSet Designer.I had tried to create a Macro in MS Access Data File but didn't know how to create & so desided not to save any & just quit from Access and came back to Visual studio. Since then only this prob. has started. Earlier to this everything was just fine.I have tried to uninstall MS Office as well as Visual Studio then Re-installed Visual Studio but the problem is still there.

I was currently looking at on old application that I am maintianing and it uses a mixture of retrieving Application config settings from both the App.config and application config table in the DB.In the new software I am working (a port of the old application) I have a list of email addresses that are static and rarely change, what would be the best mechanism for retrieving these. Currently I am using resource strings so that using them is a simple My.Resources., but what are the benefits/drawbacks of storing the information either in the App.Config or a database table.
View 3 RepliesI have googled this and found older vb codes that do not work in 2010. The user, in this case a "cheater/hacker" isn't suppose to be aware of a running program that checks memory and some other information. I have succesfully read the values of certain memory adresses in my program, now I need to send those values to another program secretly opened as a date and time sort of thing. The program checks for malicius attempts to edit memory or edit information inside the software and it automaticly deletes all the data or does a "ban" if somebody attempts to freeze memory and edit it.
So the problem is how to send this data to program out of focus, I can send strings with appactivate but it will open my security program to screen everytime memory changes witch is almost every milisecond so it's almost useless cause it keeps switching focus. I need something to send it out of focus, so my question is;
I make a hook between my program and my security program, send messages/strings out of focus or in tray?Also it would be good if I could make my program "invisible" so he can't be seen even in tray and still keep working.
I am having a windows application. That downloads files from server and write into the local directory. It works fine. When we try the same appliication in Windows 7. IT shows an error Access to the path denied (While writing to the local directory).
