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

View 1 RepliesI have been developing my application for a while and need some advice on the closing. I want a code to be run when the close button is clicked but ONLY when it is clicked.
I have dried the form.disposed but that fires whenever the form is closed from the code. I just want it to do it when the close button is clicked.If you don't understand it I will give an example. I have a registation form that is the first thing a user who has not used the app before can see. When they click the close button I want the application to exit through Application.Exit(), however when they have registered the form is closed from the code through
formlogin.show()Me.close()However the Me.closE() triggers the form.disposed event and thus the application exits completely which I don't want. I know I can use the form.hide() but that keeps it running which makes the app more resource intensive.

When the time is up 3-5 beeps happen. I am missing the coding for the 3-5 beeps and design parts for it and all coding for that along with code for setting the 2 minute timing. There is no label for telling the time left or to go just a progress bar. Here is my code so far.
