Inserting Record - Overflow Runtime Error With Data Reader
Jan 28, 2011
I am new to VB. I was trying to insert a record into access database with data reader. I was getting OVERFLOW error at runtime. My understanding is that overflow error occurs when we assign values that to variables that exceeds the maximum size of the data type.
Following is my code
Private Sub InsertRecord(ByVal CustomerID As Integer)
Dim RowArray() As String = Split(Me.lblRow.Text)
Dim intPrice As Integer
Dim decTotalPrice As Decimal
Dim mySQL As String
[Code] .....

[code] When insCommand.ExecuteNonQuery is executed, an exception with Error # -2147217900 is thrown, with the detail of "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user." At the time the error is thrown, this is what resides in strInsert: "Insert Into ScoutInfo (ScoutID, YearID, GSUSAID, FName, LName, DoB, Grade, Level, School, YearsIn, CurrentYear) Values (10000, 20092010, 123456, 'Jacobina', 'Lowe', '11/30/2009', 'K', 'Daisy', 'Thisone', 0, '20092010')" I've already verified that the Insert statement and datatypes of the columns match.

Error is thrown at "cmdDelete.ExecuteNonQuery()". Sql query still deletes the record. I have run query against the database itself and I get no error. I am using an as400 db and vb.net 2008. I'm not sure if this is problem with the database or vb. I get this error when I run the delete above, also when I run an insert or an update.

I have an error that is during the query to a database ExecuteReader 'phase' of my program, i am assigning an .OleDbDataReader to a variable RetVal and then, i am giving this RetVal = Query.ExecuteReader, and then in the while the query is being read loop(While RetVal.Read) i am getting an error in runtime that is "Invalid attempt to call Read when reader is closed." I know this means i have to open the reader, but i don't know how to do this, as i have been using this process for a few weeks and haven't had this error pop up. (and i have managed to use the while loop)If you're not living on the edge, you're taking up too much room

I have a SqlDataSource and a GridView.
What I want to do is, while the query is executed (i.e. for inserting a data), then after the data has inserted successfully, it should appear a message sounds: "The data deleted successfully". I've solved it by using GridView1_RowDeleted method.
Now the problem is, I want to catch the error while the query is failed to executed. If the query has failed to execute, then it should appear a message: "The data failed to insert."

I'm working on a form that allows to add new users to a users table in my Access database. The table only has 3 fields: user (string), password (string) and admin (boolean). user is the primary key. But when I run it and try to add, I get an error when casting the query to Double (?). I don't have any double variables or table fields, and I'm not trying to cast anything from or to double. So I have no clue about how to fix this. The code I'm using to insert (and it's working correctly on other forms and tables I have) is:

I've never seen this error before; and apparently (According to DIC) the number would have be bigger than -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, to this this exception (I'm using an Integer, but I've tried Int64, and the same thing happens).
This is where the exception is being thrown:
Dim localPort As Integer = (tcpRow__1.localPort1 << 8) + (tcpRow__1.localPort2) + (tcpRow__1.localPort3 << 24) + (tcpRow__1.localPort4 << 16)
Full Code (Method)
[CODE]...
I highly doubt that that the integer that is being parsed back is greater than, either of those numbers listed above. I've tried using Int64, and even removing the << operator, but it's still throwing this exception.

We have a VB application, which will get input from the user, post it to HTTP url and get the result from it, assigns it to objects and displays it to user.
In this flow, users are getting Run-Time error 6(Overflow). But this is not happening all the time. Iam not able to reproduce also?Would there be any other reason for this, apart from normal reasons like assinging a higher value to lower datatypes.
