I am getting an ArgumentOutOfRangeException when I try to run the following code,[code]the table that is being read has a single row of data, the database and connection are fine as I can run INSERT/UPDATES etc but wherever I have used a datareader I am getting this exception each time on the "Using reader As MySqlDataReader" line.
View 2 RepliesRecently I was working on a project in VB.NET, and I was encountering a mysterious problem with some of the DB connections. This was a project that I inherited from someone else and they had used something like this:
Dim reader As SqlDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection And CommandBehavior.SingleRow)
//after reading data
reader.Close()
It appears as though this was causing the connection to not close properly all the time. I've removed the CommandBehavior.SingleRow, and it seems to be working ok now, but I was wondering if anyone else has encountered this? Does anyone know why that would not work? I've seen CommandBehaviors combined in this way before, but it has never caused that problem before.
I am getting the following message from this code and I cant figure out how to fix it: ArgumentOutOfRangeException was unhandled

I have an unbound DateTimePicker Control on a form. When the form loads the control shows 2005 - 01 as expected. I can use the arrow keys left and right to switch between highliting the year or the month. Pressing the up and down keys to change the month doesn't work an exception is raised. I don't understand why. I started a new project. Just added a DateTimePicker and the following code.

I have a dropdownlist with a list of options which is subject to change (e.g. 'active users'). Another data source may include historical data, but I wish to use the 'active users' dropdownlist against it. This means an ArgumentOutOfRangeException will be thrown so I want to catch that, and insert the required entry into the dropdownlist on the fly.
I've seen a few suggestions that point towards overriding the ondatabinding event within the dropdownlist, I've managed to do this insofar as I can create a static listitem for example "Value does not exist" and bypass the exception. However I wish rather than "Value does not exist" so show the actual value which we were attempting to find in the ddl.
ondatabinding is passed a standard EventArgs item which doesn't offer much to go on, I can see there is a DataListItemEventArgs class - is this in any way associated with a dropdownlist? I tried directcast on the EventArgs but that didn't work.
So is there any way - within ondatabinding - of finding out the value we're attempting to set on the dll, which causes the ArgumentOutOfRangeException?

I have that so far. It was working great for the names part until I attempted to do the level part, now i get the following error:
System.ArgumentOutOfRangeException: InvalidArgument=Value of '1' is not valid for 'index'.
Also at the line where i use a goto statement to go back to the beginning of the loop, is there any way i can do that without a goto statement? Like a second loop statement or something?

I have a program using the OleDbCommand to read an indexed Access database. [code]I notice that when step debugging the program, the file is not being read in correct order.Example: it will read the record with "B" in the D01 field before a record with "A" in the same field.The record with "B" is the second record in the database.I do note that all records in the database are read before exiting the loop, just not in any apparent order.
View 5 Repliescould someone help me with some simple coding methodology for doing database searches within the ExecuteReader function that will return results regardless of case?For example, if the variable to search for within the database is John Smith,I would want the search to be successful if john smith is the user-provided variable.
