• VS2008 DataSet Wizard doesn't match tables for updating

  - by James H

  Hi all, first question ever on this site. I've been having a real stubborn problem using Visual Studio 2008 and I'm hoping someone has figured this out before. I have 2 libraries and 1 project that use strongly typed datasets (MSSQL backend) that I generated using the "Configure DataSet with Wizard" option on in Data Sources. I've had them working just fine for awhile and I've written a lot of code in the non-designer file for the row classes. I've also specified a lot of custom queries using the dataset designer. This is all work I can't afford to loose. I've recently made some changes to re-organize my libraries which included changing the names of the libraries themselves. I also changed the connection string to point to a different database which is a development copy (same exact schema). Problem is now when I open up "Configure DataSet with Wizard" to pickup a new column I've added to one of the tables it no longer matches the tables correctly in the wizard. The wizard displays all of the tables in the database and none of them have check boxes next to them (ie: are not part of this dataset). Below those it shows all of the tables again but with red Xs and these are checked. Basically meaning that Visual Studio sees all of the tables it currently has in the DataSet and sees all of the tables in the database, but believes they are no longer the same and thus do not match! I've had this same thing happen quite awhile back and I think I just re-built the xsd from scratch and manually copied the code over and then had to redefine all of the custom queries I built in the dataset designer. That's not a good solution. I'm looking for 2 answers: 1. What causes this to happen and how to prevent it. 2. How do I fix this so that the wizard once again believes the tables in its xsd are the same tables that are in the database (yes, they have the exact same names still). Thanks.

• Read alphanumeric characters from csv file in C#

  - by Prasad

  I am using the following code to read my csv file: public DataTable ParseCSV(string path) { if (!File.Exists(path)) return null; string full = Path.GetFullPath(path); string file = Path.GetFileName(full); string dir = Path.GetDirectoryName(full); //create the "database" connection string string connString = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=\"" + dir + "\\\";" + "Extended Properties=\"text;HDR=Yes;FMT=Delimited;IMEX=1\""; //create the database query string query = "SELECT * FROM " + file; //create a DataTable to hold the query results DataTable dTable = new DataTable(); //create an OleDbDataAdapter to execute the query OleDbDataAdapter dAdapter = new OleDbDataAdapter(query, connString); //fill the DataTable dAdapter.Fill(dTable); dAdapter.Dispose(); return dTable; } But the above doesn't reads the alphanumeric value from the csv file. it reads only i either numeric or alpha. Whats the fix i need to make to read the alphanumeric values? Please suggest.

• what webserver / mod / technique should I use to serve everything from memory?

  - by reinier

  I've lots of lookuptables from which I'll generate my webresponse. I think IIS with Asp.net enables me to keep static lookuptables in memory which I can use to serve up my responses very fast. Are there however also non .net solutions which can do the same? I've looked at fastcgi, but I think this starts X processes, of which anyone can handle Y requests. But the processes are by definition shielded from eachother. I could configure fastcgi to use just 1 process, but does this have scalability implications? anything using PHP or any other interpreted language won't fly because it is also cgi or fastcgi bound right? I understand memcache could be an option, though this would require another (local) socket connection which I'd rather avoid since everything in memory would be much faster. The solution can work under WIndows or Unix... it doesn't matter too much. The only thing which matters is that there will be a lot of requests (100/sec now and growing to 500/sec in a year), and I want to reduce the amount of webservers needed to process it. The current solution is done using PHP and memcache (and the occasional hit to the SQL server backend). Although it is fast (for php anyway), Apache has real problems when the 50/sec is passed. I've put a bounty on this question since I've not seen enough responses to make a wise choice. At the moment I'm considering either Asp.net or fastcgi with C(++).

• Most efficient way to send images across processes

  - by Heinrich Ulbricht

  Goal Pass images generated by one process efficiently and at very high speed to another process. The two processes run on the same machine and on the same desktop. The operating system may be WinXP, Vista and Win7. Detailled description The first process is solely for controlling the communication with a device which produces the images. These images are about 500x300px in size and may be updated up to several hundred times per second. The second process needs these images to display them. The first process uses a third party API to paint the images from the device to a HDC. This HDC has to be provided by me. Note: There is already a connection open between the two processes. They are communicating via anonymous pipes and share memory mapped file views. Thoughts How would I achieve this goal with as little work as possible? And I mean both work for me and the computer. I am using Delphi, so maybe there is some component available for doing this? I think I could always paint to any image component's HDC, save the content to memory stream, copy the contents via the memory mapped file, unpack it on the other side and paint it there to the destination HDC. I also read about a IPicture interface which can be used to marshall images. What are your ideas? I appreciate every thought on this!

• Slowdowns when reading from an urlconnection's inputstream (even with byte[] and buffers)

  - by user342677

  Ok so after spending two days trying to figure out the problem, and reading about dizillion articles, i finally decided to man up and ask to for some advice(my first time here). Now to the issue at hand - I am writing a program which will parse api data from a game, namely battle logs. There will be A LOT of entries in the database(20+ million) and so the parsing speed for each battle log page matters quite a bit. The pages to be parsed look like this: http://api.erepublik.com/v1/feeds/battle_logs/10000/0. (see source code if using chrome, it doesnt display the page right). It has 1000 hit entries, followed by a little battle info(lastpage will have <1000 obviously). On average, a page contains 175000 characters, UTF-8 encoding, xml format(v 1.0). Program will run locally on a good PC, memory is virtually unlimited(so that creating byte[250000] is quite ok). The format never changes, which is quite convenient. Now, I started off as usual: //global vars,class declaration skipped public WebObject(String url_string, int connection_timeout, int read_timeout, boolean redirects_allowed, String user_agent) throws java.net.MalformedURLException, java.io.IOException { // Open a URL connection java.net.URL url = new java.net.URL(url_string); java.net.URLConnection uconn = url.openConnection(); if (!(uconn instanceof java.net.HttpURLConnection)) { throw new java.lang.IllegalArgumentException("URL protocol must be HTTP"); } conn = (java.net.HttpURLConnection) uconn; conn.setConnectTimeout(connection_timeout); conn.setReadTimeout(read_timeout); conn.setInstanceFollowRedirects(redirects_allowed); conn.setRequestProperty("User-agent", user_agent); } public void executeConnection() throws IOException { try { is = conn.getInputStream(); //global var l = conn.getContentLength(); //global var } catch (Exception e) { //handling code skipped } } //getContentStream and getLength methods which just return'is' and 'l' are skipped Here is where the fun part began. I ran some profiling (using System.currentTimeMillis()) to find out what takes long ,and what doesnt. The call to this method takes only 200ms on avg public InputStream getWebPageAsStream(int battle_id, int page) throws Exception { String url = "http://api.erepublik.com/v1/feeds/battle_logs/" + battle_id + "/" + page; WebObject wobj = new WebObject(url, 10000, 10000, true, "Mozilla/5.0 " + "(Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 ( .NET CLR 3.5.30729)"); wobj.executeConnection(); l = wobj.getContentLength(); // global variable return wobj.getContentStream(); //returns 'is' stream } 200ms is quite expected from a network operation, and i am fine with it. BUT when i parse the inputStream in any way(read it into string/use java XML parser/read it into another ByteArrayStream) the process takes over 1000ms! for example, this code takes 1000ms IF i pass the stream i got('is') above from getContentStream() directly to this method: public static Document convertToXML(InputStream is) throws ParserConfigurationException, IOException, SAXException { DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.parse(is); doc.getDocumentElement().normalize(); return doc; } this code too, takes around 920ms IF the initial InputStream 'is' is passed in(dont read into the code itself - it just extracts the data i need by directly counting the characters, which can be done thanks to the rigid api feed format): public static parsedBattlePage convertBattleToXMLWithoutDOM(InputStream is) throws IOException { // Point A BufferedReader br = new BufferedReader(new InputStreamReader(is)); LinkedList ll = new LinkedList(); String str = br.readLine(); while (str != null) { ll.add(str); str = br.readLine(); } if (((String) ll.get(1)).indexOf("error") != -1) { return new parsedBattlePage(null, null, true, -1); } //Point B Iterator it = ll.iterator(); it.next(); it.next(); it.next(); it.next(); String[][] hits_arr = new String[1000][4]; String t_str = (String) it.next(); String tmp = null; int j = 0; for (int i = 0; t_str.indexOf("time") != -1; i++) { hits_arr[i][0] = t_str.substring(12, t_str.length() - 11); tmp = (String) it.next(); hits_arr[i][1] = tmp.substring(14, tmp.length() - 9); tmp = (String) it.next(); hits_arr[i][2] = tmp.substring(15, tmp.length() - 10); tmp = (String) it.next(); hits_arr[i][3] = tmp.substring(18, tmp.length() - 13); it.next(); it.next(); t_str = (String) it.next(); j++; } String[] b_info_arr = new String[9]; int[] space_nums = {13, 10, 13, 11, 11, 12, 5, 10, 13}; for (int i = 0; i < space_nums.length; i++) { tmp = (String) it.next(); b_info_arr[i] = tmp.substring(space_nums[i] + 4, tmp.length() - space_nums[i] - 1); } //Point C return new parsedBattlePage(hits_arr, b_info_arr, false, j); } I have tried replacing the default BufferedReader with BufferedReader br = new BufferedReader(new InputStreamReader(is), 250000); This didnt change much. My second try was to replace the code between A and B with: Iterator it = IOUtils.lineIterator(is, "UTF-8"); Same result, except this time A-B was 0ms, and B-C was 1000ms, so then every call to it.next() must have been consuming some significant time.(IOUtils is from apache-commons-io library). And here is the culprit - the time taken to parse the stream to string, be it by an iterator or BufferedReader in ALL cases was about 1000ms, while the rest of the code took 0ms(e.g. irrelevant). This means that parsing the stream to LinkedList, or iterating over it, for some reason was eating up a lot of my system resources. question was - why? Is it just the way java is made...no...thats just stupid, so I did another experiment. In my main method I added after the getWebPageAsStream(): //Point A ba = new byte[l]; // 'l' comes from wobj.getContentLength above bytesRead = is.read(ba); //'is' is our URLConnection original InputStream offset = bytesRead; while (bytesRead != -1) { bytesRead = is.read(ba, offset - 1, l - offset); offset += bytesRead; } //Point B InputStream is2 = new ByteArrayInputStream(ba); //Now just working with 'is2' - the "copied" stream The InputStream-byte[] conversion took again 1000ms - this is the way many ppl suggested to read an InputStream, and stil it is slow. And guess what - the 2 parser methods above (convertToXML() and convertBattlePagetoXMLWithoutDOM(), when passed 'is2' instead of 'is' took, in all 4 cases, under 50ms to complete. I read a suggestion that the stream waits for connection to close before unblocking, so i tried using HttpComponentsClient 4.0 (http://hc.apache.org/httpcomponents-client/index.html) instead, but the initial InputStream took just as long to parse. e.g. this code: public InputStream getWebPageAsStream2(int battle_id, int page) throws Exception { String url = "http://api.erepublik.com/v1/feeds/battle_logs/" + battle_id + "/" + page; HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(url); HttpParams p = new BasicHttpParams(); HttpConnectionParams.setSocketBufferSize(p, 250000); HttpConnectionParams.setStaleCheckingEnabled(p, false); HttpConnectionParams.setConnectionTimeout(p, 5000); httpget.setParams(p); HttpResponse response = httpclient.execute(httpget); HttpEntity entity = response.getEntity(); l = (int) entity.getContentLength(); return entity.getContent(); } took even longer to process(50ms more for just the network) and the stream parsing times remained the same. Obviously it can be instantiated so as to not create HttpClient and properties every time(faster network time), but the stream issue wont be affected by that. So we come to the center problem - why does the initial URLConnection InputStream(or HttpClient InputStream) take so long to process, while any stream of same size and content created locally is orders of magnitude faster? I mean, the initial response is already somewhere in RAM, and I cant see any good reasong why it is processed so slowly compared to when a same stream is just created from a byte[]. Considering I have to parse million of entries and thousands of pages like that, a total processing time of almost 1.5s/page seems WAY WAY too long. Any ideas? P.S. Please ask in any more code is required - the only thing I do after parsing is make a PreparedStatement and put the entries into JavaDB in packs of 1000+, and the perfomance is ok ~ 200ms/1000entries, prb could be optimized with more cache but I didnt look into it much.

• Threads, Sockets, and Designing Low-Latency, High Concurrency Servers

  - by lazyconfabulator

  I've been thinking a lot lately about low-latency, high concurrency servers. Specifically, http servers. http servers (fast ones, anyway) can serve thousands of users simultaneously, with very little latency. So how do they do it? As near as I can tell, they all use events. Cherokee and Lighttpd use libevent. Nginx uses it's own event library performing much the same function of libevent, that is, picking a platform optimal strategy for polling events (like kqueue on *bsd, epoll on linux, /dev/poll on Solaris, etc). They all also seem to employ a strategy of multiprocess or multithread once the connection is made - using worker threads to handle the more cpu intensive tasks while another thread continues to listen and handle connections (via events). This is the extent of my understanding and ability to grok the thousand line sources of these applications. What I really want are finer details about how this all works. In examples of using events I've seen (and written) the events are handling both input and output. To this end, do the workers employ some sort of input/output queue to the event handling thread? Or are these worker threads handling their own input and output? I imagine a fixed amount of worker threads are spawned, and connections are lined up and served on demand, but how does the event thread feed these connections to the workers? I've read about FIFO queues and circular buffers, but I've yet to see any implementations to work from. Are there any? Do any use compare-and-swap instructions to avoid locking or is locking less detrimental to event polling than I think? Or have I misread the design entirely? Ultimately, I'd like to take enough away to improve some of my own event-driven network services. Bonus points to anyone providing solid implementation details (especially for stuff like low-latency queues) in C, as that's the language my network services are written in.

• handling DATETIME values 0000-00-00 00:00:00 in JDBC

  - by Jason S

  I get an exception (see below) if I try to do resultset.getString("add_date"); for a JDBC connection to a MySQL database containing a DATETIME value of 0000-00-00 00:00:00 (the quasi-null value for DATETIME), even though I'm just trying to get the value as string, not as an object. I got around this by doing SELECT CAST(add_date AS CHAR) as add_date which works, but seems silly... is there a better way to do this? My point is that I just want the raw DATETIME string, so I can parse it myself as is. note: here's where the 0000 comes in: (from http://dev.mysql.com/doc/refman/5.0/en/datetime.html) Illegal DATETIME, DATE, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00 00:00:00' or '0000-00-00'). The specific exception is this one: SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. SQLState: S1009 VendorError: 0 java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1055) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:956) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:926) at com.mysql.jdbc.ResultSetImpl.getTimestampFromString(ResultSetImpl.java:6343) at com.mysql.jdbc.ResultSetImpl.getStringInternal(ResultSetImpl.java:5670) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5491) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5531)

• C#+BDE+DBF problem

  - by Drabuna

  I have huge problem: I have lots of .dbf files(~50000) and I need to import them into Oracle database. I open conncection like this: OleDbConnection oConn = new OleDbConnection(); OleDbCommand oCmd = new OleDbCommand(); oConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + directory + ";Extended Properties=dBASE IV;User ID=Admin;Password="; oCmd.Connection = oConn; oCmd.CommandText = @"SELECT * FROM " + tablename; try { oConn.Open(); resultTable.Load(oCmd.ExecuteReader()); } catch (Exception ex) { MessageBox.Show(ex.Message); } oConn.Close(); oCmd.Dispose(); oConn.Dispose(); I read them in loop, and then insert into oracle. Everything's fine. BUT: There is about 1000 files, that I can't open. They raise exception "not a table". So I google, and install Borland Database Engine. Now everything wokrs fine....but no. Now, when I'm reading files, on 1024 file exception raises: "System resource exceeded". But I have lots of free resources. When I remove BDE, everything's fine again, no "system resource exceeded" error, but I cant read all files. Help please. PS: Tried using ODBC but nothing changes.

• Query MySQL data from Excel (or vice-versa)

  - by Charles

  I'm trying to automate a tedious problem. I get large Excel (.xls or .csv, whatever's more convenient) files with lists of people. I want to compare these against my MySQL database.* At the moment I'm exporting MySQL tables and reading them from an Excel spreadsheet. At that point it's not difficult to use =LOOKUP() and such commands to do the work I need, and of course the various text processing I need to do is easy enough to do in Excel. But I can't help but think that this is more work than it needs to be. Is there some way to get at the MySQL data directly from Excel? Alternately, is there a way I could access a reasonably large (~10k records) csv file in a sql script? This seems to be rather basic, but I haven't managed to make it work so far. I found an ODBC connection for MySQL but that doesn't seem to do what I need. In particular, I'm testing whether the name matches or whether any of four email addresses match. I also return information on what matched for the benefit of the next person to use the data, something like "Name 'Bob Smith' not found, but 'Robert Smith' matches on email address robert.smith@foo".

• How to make a product catalog in C#?

  - by Ervin

  I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

• NTLM Authentication fails when behind Proxy server

  - by Jan Petersen

  Hi All, I've seen a number of post about consuming Web Services from behind a proxy server, but none that seams to address this problem. I'm building a desktop application, using Java, JAX-WS in NetBeans. I have a working prototype, that can query the server for authentication mode, successfully authenticate and retrieve a list of web site. However, if I run the same app from a network that is behind a proxy server (the proxy does not require authentication), then I'm running into trouble. I have sniffed the traffic, and noticed the following: Behind Proxy # Result Protocol Host URL 1 200 HTTP host.domain.com /_vti_bin/Authentication.asmx 2 401 HTTP host.domain.com /_vti_bin/Webs.asmx 3 401 HTTP host.domain.com /_vti_bin/Webs.asmx 4 401 HTTP host.domain.com /_vti_bin/Webs.asmx 5 401 HTTP host.domain.com /_vti_bin/Webs.asmx Without Proxy # Result Protocol Host URL 1 200 HTTP host.domain.com /_vti_bin/Authentication.asmx 2 401 HTTP host.domain.com /_vti_bin/Webs.asmx 3 401 HTTP host.domain.com /_vti_bin/Webs.asmx 4 401 HTTP host.domain.com /_vti_bin/Webs.asmx 5 401 HTTP host.domain.com /_vti_bin/Webs.asmx 6 200 HTTP host.domain.com /_vti_bin/Webs.asmx When running the code from a network without a proxy server, I successfully Authentication with the server, but when I'm behind the proxy server, the traffic is cut-off at the 5th message, and thus don't succeed. I know from the Java docs that On Microsoft Windows platforms, NTLM authentication attempts to acquire the user credentials from the system without prompting the user's authenticator object. If these credentials are not accepted by the server then the user's authenticator will be called. Given that my Authentication code is called only ones, and only as the 5th attempt, it appears as if the connection is dropped when behind the proxy server before my Authentication object is used. Is there any way I can control the behavior of Authentication module, to not have it use the system credentials? I have put the source text java class files of a demo app up, showing the issue at the following urls (it's a bit to long even in the short demo form to post here). link text Br Jan

• EC2 SSH access from fedora

  - by Randika Rathugama

• Binding a date string parameter in an MS Access PDO query

  - by harryg

  I've made a PDO database class which I use to run queries on an MS Access database. When querying using a date condition, as is common in SQL, dates are passed as a string. Access usually expects the date to be surrounded in hashes however. E.g. SELECT transactions.amount FROM transactions WHERE transactions.date = #2013-05-25#; If I where to run this query using PDO I might do the following. //instatiate pdo connection etc... resulting in a $db object $stmt = $db->prepare('SELECT transactions.amount FROM transactions WHERE transactions.date = #:mydate#;'); //prepare the query $stmt->bindValue('mydate', '2013-05-25', PDO::PARAM_STR); //bind the date as a string $stmt->execute(); //run it $result = $stmt->fetch(); //get the results As far as my understanding goes the statement that results from the above would look like this as binding a string results in it being surrounded by quotes: SELECT transactions.amount FROM transactions WHERE transactions.date = #'2013-05-25'#; This causes an error and prevents the statement from running. What's the best way to bind a date string in PDO without causing this error? I'm currently resorting to sprintf-ing the string which I'm sure is bad practise. Edit: if I pass the hash-surrounded date then I still get the error as below: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22018]: Invalid character value for cast specification: -3030 [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.

• How to loop video using NetStream in Data Generation Mode

  - by WesleyJohnson

  I'm using a NetStream in Data Generation Mode to play an embeded FLV using appendBytes. When the stream is finished playing, I'd like to loop the FLV file. I'm not sure how to achieve this. Here is what I have so far (this isn't a complete example): public function createBorderAnimation():void { // Load the skin image borderAnimation = Assets.BorderAnimation; // Convert the animation to a byte array borderAnimationBytes = new borderAnimation(); // Initialize the net connection border_nc = new NetConnection(); border_nc.connect( null ); // Initialize the net stream border_ns = new NetStream( border_nc ); border_ns.client = { onMetaData:function( obj:Object ):void{ trace(obj); } } border_ns.addEventListener( NetStatusEvent.NET_STATUS, border_netStatusHandler ); border_ns.play( null ); border_ns.appendBytes( borderAnimationBytes ); // Initialize the animation border_vd = new Video( 1024, 768 ); border_vd.attachNetStream( border_ns ); // Add the animation to the stage ui = new UIComponent(); ui.addChild( DisplayObject( border_vd ) ); grpBackground.addElement( ui ); } protected function border_netStatusHandler( event:NetStatusEvent ):void { if( event.info.code == "NetStream.Buffer.Flush" || event.info.code == "NetStream.Buffer.Empty" ) { border_ns.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); border_ns.appendBytes( borderAnimationBytes ); border_ns.appendBytesAction( NetStreamAppendBytesAction.END_SEQUENCE ); } } This will loop the animation, but it starts chewing up memory like crazy. I've tried using NetStream.seek(0) and NetStream.appendBytesAction( NetStreamAppendBytesAction.RESET_SEEK ), but then I'm not sure what to do next. If you just try to call appendBytes again after that, it doesn't work, presumably because I'm appending the full byte array which has the FLV header and stuff? I'm not very familiar with how that all works. Any help is greatly appreciated.

• SqlLite/Fluent NHibernate integration test harness initialization not repeatable after large data se

  - by Mark Rogers

  In one of my main data integration test harnesses I create and use Fluent NHibernate's SingleConnectionSessionSourceForSQLiteInMemoryTesting, to get a fresh session for each test. After each test, I close the connection, session, and session factory, and throw out the nested StructureMap container they came from. This works for almost any simple data integration test I can think, including ones that utilize Fluent NHib's PersistenceSpecification object. When I test the application's lengthy database bootstrapping process, which creates and saves thousands of domain objects, I start seeing issues. It's not that the setup and tear down fails, in fact, the test successfully bootstraps the in-memory database as the application would bootstrap the real database in the production environment. The problem occurs when the database bootstrapping occurs a second time on a new in-memory database, with a new session and session factory. The error is: NHibernate.StaleStateException : Unexpected row count: 0; expected: 1 The row count is indeed Unexpected, the row that the application under test is looking for should be in the session. You see, it's not that any data from the last integration test is sticking around, it's that for some reason the session just stops working mid-database-boostrap. And I've looked everywhere for a place I might be holding on to an old session and I can't find one. I've searched through the code for static singleton objects, but there are none anywhere near the code in question. I have a couple StructureMap InstanceScope singleton's but they are getting thrown out with each nested container that is lost after every test teardown. I've tried every possible variation on disposing and closing every object involved with each test teardown and it still fails on this lengthy database bootstrap. But non-bootstrap related database tests appear to work fine. I'm starting to run out of options and may have to surrender lengthy database integration tests in favor of WatiN-based acceptance tests. Can anyone give me any clue about how I can figure out why some of my SingleConnectionSessionSourceForSQLiteInMemoryTesting aren't repeatable? Any advice at all, about how to make an NHibernate SqlLite database integration test harness repeatable?

• OpenPeak Flash app XMLSocket Security Problem

  - by Kira

  We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain. The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message. In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843. Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error: SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048" We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not. Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed. Any ideas / suggestions?

• Web form is not updating tables, why?

  - by JPJedi

  I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db. player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online... Dim connectionString As String = "" Dim GigsterDBConnection As New System.Data.SqlClient.SqlConnection(connectionString) GigsterDBConnection.Open() Dim updatetoursql As String = "UPDATE PLAYERS SET FIRSTNAME = '" & player.FIRSTNAME & "', LASTNAME = '" & player.LASTNAME & "', ADDRESS = '" & player.ADDRESS & "', CITY = '" & player.CITY & "', ZIP = '" & player.ZIP & "', PHONE = '" & player.PHONE & "', EMAIL = '" & player.EMAIL & "', REFFEREDBY = '" & player.REFEREDBY & "' " updatetoursql = updatetoursql & "PLAYERID = '" & player.PLAYERID & "';" Dim cmd As New System.Data.SqlClient.SqlCommand(updatetoursql, GigsterDBConnection) Dim sqlAdapter As New System.Data.SqlClient.SqlDataAdapter(cmd) sqlAdapter.Update(ds, "PLAYERS") I think the issue is something the 3 last lines of the code. am I doing it right or is their a better way?

• Why do my Sax Parser produce no results after using InputStream Read?

  - by Andy Barlow

  Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

• Log off from Remote Desktop Session does not closing Session, showing the login screen again on Wind

  - by Santhosha

  Hi As per requirement we have written one custom GINA. I have observed one interesting behavior in Windows XP 32 Bit(SP2). Customized GINA internally calls windows default Windows GINA(msgina.dll) and shows one extra window as per our requirement. I used to do remote desktop to XP machine from my machine. After replacing Windows GINA with customized GINA I tried to log off from the XP Machine(I am Using Remote Desktop Connection to log in), Log off completes successfully(After showing saving your settings, Closing network connections etc) and I will get log in screen which we get during log on, this is not expected comapred to other flavors of Windows OD. Where as in other operating systems such as Windows XP 64 Bit/ Windows 2003 32/64 Bit even after replacing the Windows Gina with custom GINA remote desktop session closes after log off from the machine. I have tried installing Novell GINA on Windows XP 32 Bit but i have not find any issue with that. I have Tried upgrading XP SP2 to SP3, still i am facing the same issue. Whether anyone faced Such issues when worked with Windows GINA? Thanks in advance Santhosha K S

• Multiple routers, subnets, gateways etc

  - by allentown

  My current setup is: Cable modem dishes out 13 static IP's (/28), a GB switch is plugged into the cable modem, and has access to those 13 static IP's, I have about 6 "servers" in use right now. The cable modem is also a firewall, DHCP server, and 3 port 10/100 switch. I am using it as a firewall, but not currently as a DHCP server. I have plugged into the cable modem, two network cables, one which goes to the WAN port of a Linksys Dual Band Wireless 10/100/1000 router/switch. Into the linksys are a few workstations, a few printers, and some laptops connecting to wifi. I set the Linksys to use take static IP, and enabled DHCP for the workstations, printers, etc in 192.168.1.1/24. The network for the Linksys is mostly self contained, backups go to a SAN, on that network, it all happens through that switch, over GB. But I also get internet access from it as well via the cable modem using one static IP. This all works, however, I can not "see" the static IP machines when I am on the Linksys. I can get to them via ssh and other protocols, and if I want to from "outside", I open holes, like 80, 25, 587, 143, 22, etc. The second wire, from the cable modem/fireall/switch just uplinks to the managed GB switch. What are the pros and cons of this? I do not like giving up the static IP to the Linksys. I basically have a mixed network of public servers, and internal workstations. I want the public servers on public IP's because I do not want to mess with port forwarding and mappings. Is it correct also, that if someone breaches the Linksys wifi, they still would have a hard time getting to the static IP range, just by nature of the network topology? Today, just for a test, I toggled on the DHCP in the firewall/cable modem at 10.1.10.1/24 range, the Linksys is n the 192.168.1.100/24 range. At that point, all the static IP machines still had in and out access, but Linksys was unreachable. The cable modem only has 10/100 ports, so I will not plug anything but the network drop into it, which is 50Mb/10Mb. Which makes me think this could be less than ideal, as transfers from the workstation network to the server network will be bottlenecked at 100Mb when I have 1000Mb available. I may not need to solve that, if isolation is better though. I do not move a lot of data, if any, from Linsys network to server network, so for it to pretend to be remote is ok. Should I approach this any different? I could enable DHCP on the cable modem/firewall, it should still send out the statics to the GB switch, but will also be a DHCP in 10.1.10.1/24 range? I can then plug the Linksys into the GB switch, which is now picking up statics and the 10.1.10.1/24 ranges, tell the Linksys to use 10.1.10.5 or so. Now, do I disable DHCP on the Linksys, and the cable modem/firewall will pass through the statics and 10.0.10.1/24 ranges as well? Or, could I open a second DHCP pool on the Linksys? I guess doing so gives me network isolation again, but it is just the reverse of what I have now. But I get out of the bottleneck, not that the Linksys could ever really touch real GB speeds anyway, but the managed switch certainly can. This is all because 13 statics are not that many. Right now, 6 "servers", the Linksys, a managed switch, a few SSL certs, and I am running out. I do not want to waste a static IP on the managed GB switch, or the Linksys, unless it provides me some type of benefit. Final question, under my current setup, if I am on a workstation, sitting at 192.168.1.109, the Linksys, with GB, and I send a file over ssh to the static IP machine, is that literally leaving the internet, and coming back in, or does it stay local? To me it seems like: Workstation (192.168.1.109) -> Linksys DHCP -> Linksys Static IP -> Cable Modem -> Server ( and it hits the 10/100 ports on the cable modem, slowing me down. But does it round trip the network, leave and come back in, limiting me to the 50/10 internet speeds? *These are all made up numbers, I do not use default router IP's as I will one day add a VPN, and do not want collisions. I need some recommendations, do I want one big network, or two isolated ones. Printers these days need an IP, everything does, I can not get autoconf/bonjour to be reliable on most printers. but I am also not sure I want the "server" side of my operation to be polluted by the workstation side of my operation. Unless there is some magic subetting I have not learned yet, here is what I am thinking: Cable modem 10/100, has 13 static IP, publicly accessible -> Enable DHCP on the cable modem -> Cable modem plugs into managed switch -> Managed switch gets 10.1.10.1 ssh, telnet, https admin management address -> Managed switch sends static IP's to to servers -> Plug Linksys into managed switch, giving it 10.1.10.2 static internally in Linksys admin -> Linksys gets assigned 10.1.10.x as its DHCP sending range -> Local printers, workstations, iPhones etc, connect to this -> ( Do I enable DHCP or disable it on the Linksys, just define a non over lapping range, or create an entirely new DHCP at 10.1.50.0/24, I think I am back isolated again with that method too? ) Thank you for any suggestions. This is the first time I have had to deal with less than a /24, and most are larger than that, but it is just a drop to a cabinet. Otherwise, it's a router, a few repeaters, and soho stuff that is simple, with one IP. I know a few may suggest going all DHCP on the servers, and I may one day, just not now, there has been too much moving of gear for me to be interested in that, and I would want something in the Catalyst series to deal with that.
