I need to go through a list of strings and count the number of duplicates and then print the string with the number of occurrences in one line to a file. Here is what I have but I need to only print the string once and its count.

am working on an app that generates 2 random numbers. When the numbers match it plays a sound. I'm trying to keep count of each time this accurs by using a label to hold the number each time it counts. It's working but when I use a label it only counts up to 9 then goes back to one and stays there. Here is a snippet of the code I wrote.

I'm trying to match up a specific group name and see if it exists for the currently logged in user using Active Directory roles. If the Group Name exists for the Current User, I want that group name to be displayed in a drop down list.

I have a timer that basically counts a number up in sequence in a label. On the On Text Change sub for the label I have functions run when the label is at a specific number. Everything works fine, the only problem I have is I have information pulled from an ODBC link to a pervasive database every second, which slows down the program. I have several flash components that run so slowly because of the data update. Now I have tried both using a dataset and coding the query but it is still ver slow and processor intensive, I think its because the Pervasive ODBC link is somewhat slow. Is there a way to have my data pull timer run in the background so that it doesnt effect the performance of the rest of the program?

myListbox.Items.Add(txtText.Text & "")

I'm trying to make this program that counts the frequency of each letter in the alphabet for a set of ciphertext, the calculation i want to do is:lettersum*(lettersum - 1) + lettersum*(lettersum - 1) for however many letters example: User puts aabbcc in the ciphertext box , the output should be
2(2-1)+2(2-1)+2(2-1) =6 If the user inputs aaaaab the output should be 5(5-1)+1(1-1) = 20 The code I have so far only counts the last number of letters for example: aabbcc only reads the cc part and only outputs 2(2-1) = 2 instead of 2(2-1) + 2(2-1) + 2(2-1) = 6.The code below is part of a button_Click item

I have a Windows form which contains a DataGridView within a GroupBox which is within a TabPage which is within a TabControl.The scrollbars property is set to 'Both' so that the user can scroll down to see all available rows in the grid.
I want the Windows Form to initialize to allow the user to see 7 rows but to expanded vertically to the size of 32 rows which is the maximum possible in this application.
Is there a way to size the form dynamically so the Form's Height property can be changed as the DataGridView's rowcount increases?
i'm new at vb.net (though i have extensive vb6 experience and oracle experience), and i need a sample program/project which uses multiple queries (of the same oracle database namespace) to display counts in text boxes.user will use a pull down list to select action from there.
