I have a method is code behind like this:
Code:
[code]....
but it doesn't print out anything. IsLocked in the db is integer type. It should print out "1" .. If I just do Eval("IsLocked") then it prints out 1..
I get the error - Conversion from type 'DBNull' to type 'Integer' is not valid. - on the line.....
Dim newid As Integer = e.Command.Parameters("@latestRowId").Value.........in vb code behind.
I have the identical code for another page with the exception of the field names and it works fine. The only thing I did differently, as far as I know, is I copied the asp and code behind from the page that works into this page and manually changed the field and table names. I don't know what the problem is. Does anyone see any problems?

We are using visual studio 2005 and SSMSE for this project. I had already created some pages which is capable of inserting and updating the values on the sql server. After inserting and updating it will redirect to another page to view the result. When I add a homepage, something just mess up. When I insert a new items for the table, it prompts a message, DBnulls cannot be converted to type integer. When I try to check at the sql tables, the data was inserted but I was not able to view the result on the other page.

I'm unable to fetch just one integer value using this LINQ-query. LINQ seems to return everything as IEnumerable but I don't want that. First query should return just one string value which is then used in another query. That one should return integer which is also return value for method:
public static long GetTableIdByTableName(string name)
{
var result = (from aTable in objScope.Extent<Table>()
where aTable.Name == name
select { aTable.Id });
return ???????????
}
How can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))
i am trying to read file from a stream.
and i am using stream.read method to read the bytes. So the code goes like below
FileByteStream.Read(buffer, 0, outputMessage.FileByteStream.Length)
Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.

Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.

The program (asp.net/vb) works fine with FormView1_ItemCommand and FormView1_ItemInserted events but strangely objects to FormView1_ItemCreated. Is it only a VC# event?
