OutOfMemoryException
(Thursday, January 27, 2005)
Found the following interesting discussion in the Newsgroups:
OutOfMemoryException
by:Fredrik Melin
| In the following code I get an OutOfMemoryException when trying to store a
16.7 MB file. (16773738 bytes)
The error is raised on the code: Dim b(fs.length-1) as Byte
Is there a limit on how large byte array you can declare? If so, How can I
store the file in the database?
Regards

/// CODE BELOW
Dim dbConn As SqlClient.SqlConnection
Dim cmSQL As New SqlClient.SqlCommand("UPDATE
EDI_MESSAGE_QUE SET XML_MESSAGE_CONVERTED = @BLOB WHERE BATCH_ID_XREF =
@BATCH_ID", dbConn)
Try
If dbTrans Is Nothing Then
dbConn = New
SqlClient.SqlConnection(DacsaSystemObject.ConnectionObject.sConnection_Strin
g)
dbConn.Open()
dbTrans =
dbConn.BeginTransaction(IsolationLevel.Serializable)
bLocalTransaction = True
Else
dbConn = dbTrans.Connection
End If
cmSQL.Connection = dbConn
cmSQL.Transaction = dbTrans
cmSQL.CommandTimeout = 900
Dim fs As New System.IO.FileStream(File_Name,
System.IO.FileMode.Open, System.IO.FileAccess.Read)
Dim b(fs.Length - 1) As Byte
fs.Read(b, 0, b.Length)
fs.Close()
Dim P As New SqlClient.SqlParameter("@BLOB",
SqlDbType.Image, b.Length, ParameterDirection.Input, False, 0, 0, Nothing,
DataRowVersion.Current, b)
cmSQL.Parameters.Add(P)
cmSQL.Parameters.Add("@BATCH_ID", Batch_ID)
If cmSQL.ExecuteNonQuery = 0 Then
Throw New Dacsa_Exceptions.Critical("Failure to save
XML Message que job")
End If
Erase b
b = Nothing
If bLocalTransaction Then dbTrans.Commit()
'RaiseEvent Status_Changed("Message saved!")
Return True
Catch ex As Exception
ErrReport.RegisterError(ex)
Finally
If bLocalTransaction Then dbConn.Close()
cmSQL.Dispose()
End Try

| | | Problem is that fileStream dont like integer or long...
Strange:
Dim b(16773738) As Byte does NOT work
Dim b(17773738) As Byte WORKS!
