View 3 RepliesI 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.

View 5 RepliesI am reading a text file in which has three colums of information i.e.
00100 25690 21586
23510 25694 24856
25896 45478 52897
58745 59687 12364
I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.

View 4 RepliesI am trying to write login page code for the login button but can't find how to find a string in a .txt file. The only code I have managed to find on the subject is opening up the text file with the
FileOpen(1, "File location", OpenMode.Output) code, but even this would be best removed as it would open the text file containing all usernames and passwords within the file.I need the system to search for a specific string within a file ( Usernames___Passwords.txt (159bytes)Number of downloads: 134), and with that string find the password associated with it (in my attached example the letters/words after the apostrophe) but stopping at the end of the line.

I have a situation where I have a vb.net program that uses two connection strings. This program will be used on multiple web servers on multiple domains and the only difference for any of them is the two connection strings.What would be the best solution to read in these connection strings from a file separate from my actual .vb code?
Ideally I want to be able to drop the .vb and the connection string file into its own folder on any number of asp.net websites and not update anything else (for example add any connections to the web.config or anything) than the external file containing the connection strings, I assume something like xml would suffice?
Imagine there is a very large html file with of course lots of html tags. I cannot load the entire file into memory. My intention is to extract all indexes for this <p> and this </p> strings. How should I achieve it?

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 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.
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?

The problem is that this will just overwrite what is already there. I would like to have it append the EHomeLog.log every time it is called.
I'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).
