connection

When I invoke following rows: Statement statement = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY); ResultSet resultSet = statement.executeQuery("select * from user"); resultSet.next(); resultSet.refreshRow();//exception throws here I see following exception: com.mysql.jdbc.NotUpdatable: Result Set not updatable.This result set must come from a statement that was created with a result set type of ResultSet.CONCUR_UPDATABLE, the query must select only one table, can not use functions and must select all primary keys from that table. See the JDBC 2.1 API

I think of using in windows a named pipe to communicate between two apps written in Java and C. Normally i use socket connection to do this, but now i have to cancel this idea and find a new solution. I read that named pipe in java can be visible only inside JVM-is this true? Is there a way to establish named pipe between two apps wriiten in different language? If not, what kind of technology do You advice? In order to create a Windows named pipe in Java, you'd have to resort to using JNI to call the native WINAPI functions. You can create the named pipe in C++, though, and consume it in Java

We have a client/server application that consists of multiple EXEs. The data access layer is on the same physical tier as the client in a library shared by our EXE modules. ODBC and OleDB connection pools are managed per-process; are there techniques for sharing DB connections across processes (other than moving the data access layer to a middle tier)? Database connections in OLEDB and ODBC are intrinsically process bound. At the lowest levels, a sql server database connection is using an IPC mechanism like named pipes, shared memory, or tcp sockets. Other databases probably use network

I use vs2008, winxp, in LAN network with Win2003 servers. I want a application installed in winxp for detect if win2003 machines is online or offline , and if offline when boot it. I have this references, any more references, code samples and best practices ?? http://danielvl.blogspot.com/2004/06/how-to-ping-in-c-using.html http://snipplr.com/view/2157/ping-using-wmi-pingstatus/ http://dotnoted.wordpress.com/2005/01/15/the-popular-c-ping-utitility/ http://www.visualbasicscript.com/Ping-WMI-amp-NonWMI-Versions-Functions-amp-Simple-Connectivity-Monitor-m42535.aspx I would go for the .NET System

Java applications may use IO streams, sockets or database connections that should be closed when they are no longer needed. However, applications may be terminated (e.g. by killing the process). Will all used resources be freed in this case? Who will free them: OS or JRE? haylem If your software doesn't take care of resource management properly, the following will happen: at runtime: the JVM will attempt during the duration of your program to close open streams if they're are seemingly unused (during garbage collection cycles), at your program's termination point: the JVM should close open

Requirement I have an On-Premise SQL Server and an Azure webApp Service that needs to talk each other. I installed Hybrid Connection Manager on another computer which is in the same LAN as the SQL server. Let's refer this computer as the Connection PC . The working part Installation and configuration was straight forward, status of the hybrid connection showing as connected. Tested the WebApp on localhost, it worked fine. Which means nothing wrong with the asp.net code SSMS on the connection PC can access and query SQL DB I installed a test SQL DB on the connection PC itself and use the WebApp

i have a "Connection.vb" where all my Connection string stored and used by the entire program. i'm new to Crystal Reports.. and i want to changes its connection string based on the connection string i made... im using MS SQL 2008.. SQL Server Native Client 10.0 OLE DB Provider.. and here is my connection string. "Provider=SQLNCLI10;Server=....\SQLEXPRESS;Database=Blah;Trusted_Connection=yes" i tried to google it.. but they are using different language, different database, and complex examples... thanks in advance.. I just spent some quality time figuring out this exact problem, in VB. I hope
