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
If ltbList.SelectedItem(IntrotoECommerce) And ckbConferenceRegistration896.CheckState = CheckState.Checked Then

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.

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]...

I am working with a listbox that contains reportnames. Some reports will have parameters, some will not. This application lets users view and run SSRS reports. It also allows them to send email messages to one or more recipients with a web link to the SSRS report using Report Viewer. What I have done with the listbox is whenever a report that has parameters associated with it, the control (DateTimePicker) appears on the screen for the user to pick a date. When a report with no parameters is selected, it simply changes the Visible property of the DateTimePicker to false so the user won't have to use it. Everything works fine, I am able to pick a report with parameters passed as part of the link that gets sent via email to user. User clicks on it and report gets displayed with the correct parameters in the ReportViewer. However when I exit out, I get this IndexOutOfRangeException exception. Here is my code for listbox -
Private Sub lstBxReportName_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstBxReportName.SelectedIndexChanged
Dim y As Integer
[code]....
When I debug, error is on second Dim statement for rowViewReportNameChange. I guess I can simply include the Dim statements as part of my Try block and I can catch the exception?
This code, which I got from [url]).aspx has been kicking up an error message (and a warning) when I try to use it.
View 1 RepliesPicked up a legacy VB.NET project originally written for version 1.1 of the .NET framework. I'm running Vista with .NET 3.5. I have cleared out all the original error and the project will build; it just wont run.
As far as I can tell, it is trying to run 'LoginForm' but putting breakpoints in doesn't work because the error is thrown before the breakpoints are reached, regardless of where in the file they are placed.

My ConnectionString is working fine.
I've saved my SQL command in a string as follows: Dim sqlcmd As String = "select LEFT(eventDate,10) from Locations"
Dim sqlreader As SqlDataReader
Then I open my connection and at that point everything is fine.
I can execute the query just fine but the error comes up when I try to fill data into my webapp.
sqlreader.Read()
loc1Date.Text = sqlreader("eventDate").ToString() ---------- This is the line that is giving me the error "System.IndexOutOfRangeException: eventDate"
I just want the date pulled and not the time. get this date to fill into my textbox on my webapp.
