I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). 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)..."

While trying to open a form I get the following error:
An error occurred creating the form. See Exception.InnerException for details. The error is: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Previously the form loaded flawlessly. I made several small changes to subs contained in the form, and after that the problem appeared. These changes included some changes in the constructor. I've tried to track down the problem simply by adding message boxes near potential problem areas, and it seems that the exception is thrown before the constructor is even run. The error message baffles me, since I'm not knowingly using any parameters, and the routine opening the form doesn't refer to any arrays (or any other variables).
Here is the part of the source code that the error message refers to:
Private Sub SugNewTagsBtn_Click(ByVal sender As System.Object, ByVal As System.EventArgs)
Handles SugNewTagsBtn.Click
SugNewTagsForm.Show()
End Sub

So i want to grab information from a certain column in a database, however the user pics the column by the column name so it is a variable in the code
Dim SQL As String = "SELECT '" & Night & "' FROM TblContacts" ' WHERE Phone = '" & incomingtextno & "'"
Dim myOleDbCommand As New OleDb.OleDbCommand(SQL, con)
Dim current_count As Integer
con.Open()
[code]....
The user chooses the "night" then the program grabs the value from the column with that variable name, except i think i hav e the wrong syntax because i get the error "Index out of range exception was unhandled" - this pops up on the line
current_count += myDataReader.Item(Night).ToString and is pointing at the word Night.By the way when I say column the technical term maybe field, however it is a column in the database entries...

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?

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 am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?
