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)..."

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I don't understand why this piece of code is getting an Index out of range exception. I checked the column names and they are OK. The same code was used for another database and ran without problems. Both databases are in Access.

I'm trying to grab the values that have changed using the GridView_RowUpdating event.
Here is my code:
Dim newValues As String = ""
Dim oldValues As String = ""
Dim i As Integer
Dim j As Integer
[Code] .....
Weird thing is, it seems to pull OldValues fine, but when I try to pull the NewValues I get an "Index was out of range." Checking around I see that this sometimes occur if you have non-BoundFields in your Gridview, but all of my fields are bound!

I was trying to add two quantities at different rows of same description i.e same product_name and same item_pack.1st I want to check the table if it contains the same description or not by comparing with the first record and so on. When found, I'll add up the quantities and then to delete that particular row (to avoid duplicate search). But when I delete the row the particular row, next time it throws an out of index exception

I keep getting the error message "Index out of range exception" when I run the following code.
XX
GN3 = (Loops * 5)
For a = 1 To Loops
For b = 1 To GN3
R1 = Seeds1(Counter1)
Randomize()
R2 = CInt(Int((56 * Rnd(R1)) + 1))
Counter1 += 1
MessageBox.Show(R1 & " " & Counter1 & " " & b & " " & GN3)
Next b
Next a
The message box conforms that the last entry in the array has been reached. And that Counter1 and b both start at 1 and go to 2845. And that GN3 is also 2845 all of the time.

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...

To the point: I need to transfer a custom object's event through a generic collection object containing these items so that any class using the collection can see that changes were made to one of the items in the collection.
I.E. An item event that triggers a collection event
[Code].....
Due to the application requirements, I need the Collection and Items to send immediate notice of various changes that occur to the Collection Class and its items. I've already got my events set-up regarding for the Collection Class, but I'm struggling with coming up with a workable solution for raising events for the items.
I've got an event for the DeviceLayer item set-up, but how do you transfer that event through the CollectionClass so that any other class using it will see that there was a change to one of the items in the collection?

I have several custom classes in a VB.NET (VS2008) project which are related to each other through generic list collections. The lower tier classes refer directly to some of the parent classes (to make it easier to refer backwards up the chain). My question is, is it possible to add the reference to the parent class when the item is added to a collection, when that collection is a property?
Below is some sampling of code to illustrate.
Public Class FlexServer
Private m_FlexLicenses As List(Of FlexLicense)
Private m_Modules As List(Of FlexModule)
Public Property FlexLicenses() As List(Of FlexLicense)
[code] .....
In the code above I have the FlexServer class which refers has two lists as properties, one for FlexLicense and one for Modules. The FlexLicense class has a property to refer back to the FlexServer class that "owns" it. In order to update this property in code, I have to add the FlexLicense to the FlexServer.FlexLicenses list AND set the FlexLicense.FlexServer property. What I am looking for is, is there a way (in the property definition or wherever) to both add the item to the list and alter it at the same time?

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?

Then build a datagridview with the staging of compressors from all off to all on for each compressor up to 10 compressors.I am trying to insert headers from 1 to 10 compressors (Variable) with the text "Comp1", "Comp2", etc....Two rows with header. I am trying to use an array with index number to insert the text, but that is where my problem happens."Index was out of range".Here is my code

I'm trying to catch a user defined permission exception - i.e. a user does something their level of system access won't allow, permission exception is thrown. My problem is, the exception is caught and then rethrown as a genertic System.Exception.Is there any way I can deduce the original exception type, without resorting to string comparisons, like if ex.ToString.Contains("Permission denied"

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?
