I was testing out an application that I created which then I recieved an error as said in this topic title. The application that I am making is one where it requires 2 form GUIs, my main one is called frmConferenceRegistrationSystem (the first picture) and my secondary one is called frmConferenceOptions (The second picture) and what they are supposed to do overall is total up the cost of registering for a conference that is selected in frmConferenceOptions and the error that I am recieving is within the ElseIf statements in the frmConferenceOptions form (third picture and first section of code) And also here is the rest of my code for both of my form GUIs at the bottom of this topic

i have just started learning vb and am enjoying it but am having problems. i want to design a three-way dictionary that allows a user to type in a word (English, Kazakh, or Russian) and have that word translated into the other two languages. The user can also add his/her own words and translations to the dictionary.My dictionary is called: "dictionarykre" and is formatted as follows: engword=kazword=rusword. i am reading the dictionary line by line and parsing it with "=", then putting the words into arrays.i keep getting the following error intermittently: IndexOutofRangeException was unhandled. Index was outside the bounds of the array. The error throws on the "KazListBox.Items.Add(arraytextfile(1))" line.i change the dictionary and the program will work for awhile, then the error will occur again.

What I have is a user control that has two RichTextBoxes. In the user control, there is RichTextBox1's TextChanged event, I want it to set RichTextBox2's Text to the same as RichTextBox1's Text, I'm currently using: RichTextBox2.Text = RichTextBox1.Text. The user control is on the main form, when I run the application and type I get this error: StackOverflowExecption was unhandled. [Code]

The code below is used to check if the application setting, an arraylist is populated or not via the count method.
When running the program fails with error "NullReferenceException was unhandled" as initially the setting (arraylist) will contain no values.In similar circumstances I would declare a new instance of the object or set value to string.empty or check if DBNull.
I know application settings have a save method but to reference/load them one is not needed.I also left the value field in the projects -> settings to be empty.[code]...

Basically, what this code is supposed to do is compare the text inputted in the input textbox with the text of the string answerstring. It seems to successfully compare the two, but every time I type the first char into the input textbox the program crashes, givingmythe Out of Range Exception. I assume it means the Char() "array" thats built into vb is out of bounds, however as i've set the while loop so that it only is executed when the whilecount is less than both the length of the input textbox and the answerstring, I don't see how it could be out of bounds.
