VS 2008 SQLDatareader IndexOutOfRangeException?

Mar 9, 2010

My code where errors occurred:

strSQL = "select * from transactions where TransactionID='" + txtTransactionID.Text + "'"
ReaderQuery(strSQL)
While dr.Read

[code].....

The weird thing about this, is that when I first run it, I was able to Bind it to all the Textbox and thought everything went smoothly, but when I run it again without any changes in that code, that error suddenly appears... sometimes that error went to other dr.item(""

Oct 7, 2011

i have a small project that basically connects to a mysql database online and displays the records in a listview.

But database2 has ID,Username,Password and not the other 2 colums.

So i have this If reader("Version") = IndexOutOfRangeException Then

Vb 2008 Intermittent IndexOutofRangeException Was Unhandled?

Feb 11, 2010

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.

VS 2008 Field Names Of A SqlDataReader Object?

Mar 2, 2010

I want to write a routine that loads a table (or query) and outputs it to a text file, with the field names in the first row.If I load the data via an adaptor class into a datatable, I can access the field names by something like DataTab.Columns(i).ColumnName.

As I only want to read the data from the table, using SqlDataReader would be more efficient. But how can I then find what the header or column names are? The following code fails with a message that the SqlDataReader class does not have a member called 'Columns ':

Dim sqlCmd As SqlClient.SqlCommand = New SqlCommand(SQL, Connection)
Connection.Open()
Dim Reader As SqlClient.SqlDataReader = sqlCmd.ExecuteReader()
Dim FName0 As String = Reader.Columns(0).ColumnName() '<==FAILS
Is there a way to find the column names of an SqlDataReader object?

'System.IndexOutOfRangeException' With .Char()?

Jun 28, 2011

Private 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.

VS 2005 IndexOutOfRangeException Error

Oct 21, 2010

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?

IndexOutOfRangeException (Index Was Outside The Bounds Of The Array)?

Jun 3, 2009

I'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.

Public Class tableForm
Private tfColumnInteger, tfRowInteger As Integer
Private DataSet As DataSet = New DataSet("HTML Parser")
Private Table As DataTable = DataSet.Tables.Add("Table")

Scrollnig DataGridView Causes System.IndexOutOfRangeException?

Jul 21, 2010

I 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.

.net 3.5 - Run 'LoginForm' But Putting Breakpoint But Getting Error IndexOutOfRangeException ?

Jun 9, 2009

Picked 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.

Asp.net - Avoid IndexOutOfRangeException Indexing DataReader Columns?

I am having a little trouble with an 'IndexOutOfRangeException'. I think it is because when the code tries to get the DateModified col from the database it sometimes contains NULLS (the users haven't always updated the page since they created it).

Here is my code;

.Net SqlDataReader Item Is Null?

Jun 21, 2011

I'm building a custom calendar control that queries our database to display corporate events. Here is the situation, there is an EndDate value stored and on the dev system one of the events have a NULL value. No big deal since it's only a test system, but might as well check before trying to use it anyway on the safe side. I figured the following code would work:

While dr.Read()
corporateTable.Rows.Add(New Object() { _
Convert.ToDateTime(dr("EventBeginDate")) _

[code]....

The thing that really gets me is, at one point I had this:

, IIf(dr.IsDBNull(column), Convert.ToDateTime(dr("EventBeginDate")).AddDays(1), Convert.ToDateTime(dr("EventEndDate"))) _

Thinking that it should work because it should only evaluate the dr() if it's not NULL. However, it kept erroring out at the end because the value was in fact NULL.Why is it that even though I'm checking if it's NULL before using the value, it errors out at the part that doesn't get called unless it's not NULL? Does it have to do with the fact that I'm using the IIF() and it's evaluating the whole statement? Or, using the dr(), it evaluates at runtime?
