VS 2008 - Index Outside Of Array Runtime Error
Apr 18, 2009
I just recently started getting an index out of bounds error on one of my arrays at runtime. I was not having this issue previously. It only seems to happen when several items are added to a listbox.
Here is my declaration and code.
Dim ClientActiveMedProbs(frmmain.lstActiveMedProbs.Items.Count) As String
'store all active medical problem information in an array & build a string
For i As Integer = 0 To frmmain.lstActiveMedProbs.Items.Count - 1
ClientActiveMedProbs(i) = frmmain.lstActiveMedProbs.Items.Item(i).ToString
[Code] .....
The actual error message is:
Index was outside the bounds of the array.

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?

During Runtime I am getting this error. ArgumentOutOfRangeException was unhandled. "index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I have attached some code that i have converted from Java to vb.net with the assistance of tangiblesoftwaresolutions.com Java to vb & c# converter and serveral vb.net experts on this site.I have attached a snippet of the code where the error is showing up.
Dim host As String = propertyFileValues.getHost()
Console.WriteLine("host: " & host)
Dim password As String = propertyFileValues.getPassword()
Console.WriteLine("password: " & password)

I'm trying to get the date and time in the database and see if it has a conflict on the textboxes that I have in my form. I use the DateDiff to see if there was a conflict but instead, I got an error. In vb6.0, I've done this code and there were no errors so far when I run it.

I am trying to split text in a TextBox and I get this error {"Index was outside the bounds of the array."} while using this code
Dim s As String = Me.RichTextBox2.Text
Dim parts() As String = s.Split(":"c)
Me.TextBox1.Text = (parts(0))
Me.TextBox2.Text = (parts(1)).Trim
I am stock, it will work fine for a couple of reads, since the Me.RichTextBox2.Text text changes constanly but every now and then I get the error

I have the following code below which has an error. When the checkbox is set to true and for example change the "role", and click save the following error is given;"Index was outside the bonds of the array". The TxtPayCont is a concatenation of title, fname, and lname in an array. Therefore, if all the fields have values, then it works fine. So if it is Mr Jones Tim, this works, but, if it is Mr Jones it doesnt not. It has to have 2 spaces to work.
If chkPayCont.Checked = True Then
Try
'* Function to split the Contact Name
Dim PayCont As String() = Regex.Split(TxtPayCont.Text, " ")

I have set my datasource on my datagridview to be a subset of rows as follows:
dg.DataSource = myDataSet.testTable.Select("id=" & id)
But I get a runtime error that Operator '=' is not defined for types 'Object' and '1-dimensional array of DataRow' There should be an easy way to do this that doesn't involve creating new tables, etc.

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

I am experiencing a perplexing error ("Index was outside the bounds of array") that did not surface a few days ago WITH THE CODE UNCHANGED.
I was even able to successfully create an executable file a few days ago. It was therefore a shock to be given this error when testing it today.

Dim GearArray(lines.GetUpperBound(0), 8) As String For x As Integer = 1 To lines.GetUpperBound(0)
Dim parts() As String = lines(x).Split(",")
