'System.IndexOutOfRangeException' With .Char()?
Jun 28, 2011Private Sub TbxInput_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TbxInput.KeyUp
[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.
Scrollnig DataGridView Causes System.IndexOutOfRangeException?
Jul 21, 2010I have a situation where I have a databound datagridview and if you try to scroll to the bottom about half way there it generates a System.IndexOutOfRangeException. However if you click on one of the header columns, causing a sort to occur, before you try to scroll all is well. Any ideas as to why I can only scroll my datagridview after it has been sorted and not before? Interesting enough if I click 'OK' it just re-generates the error. This occurs several times over and I can see the rows in the datagridview being blanked out one by one with each click of 'OK' until all visible rows are gone and then...poof...all seems fine again and I can scroll and click like normal.The first screen shot is of the initial error dialog. The second is a shot of what is happening to my datagridview as I click through the series of resulting error dialog boxes.

I've saved my SQL command in a string as follows: Dim sqlcmd As String = "select LEFT(eventDate,10) from Locations"

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.

Error IndexOutOfRangeException Was Unhandled
Nov 14, 2009I 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

VS 2005 IndexOutOfRangeException Error
Oct 21, 2010I 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?

IndexOutOfRangeException (Index Was Outside The Bounds Of The Array)?
Jun 3, 2009I've been trying to build this application with vb .net 2005 for the last couple of weeks in a computer programming class. The purpose of the program is to parse data from an html table displayed in the webbrowser and display it in a datagridview format (I plan on expanding it later). I've coded pretty much everything, but I keep getting an error related to the arrays that neither I nor my teacher can figure out. I attached a zip file of the complete project, in case anybody who was willing to look at it needed the rest of the program. I also included an "Items.htm" file with a html table in case people wanted to test running the program.

Vb 2008 Intermittent IndexOutofRangeException Was Unhandled?
Feb 11, 2010i 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.

.net 3.5 - Run 'LoginForm' But Putting Breakpoint But Getting Error IndexOutOfRangeException ?
Jun 9, 2009Picked 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.

Error: A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll
May 5, 2011I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?
