  • method to find my UDP socket's "real" port?

    - by yairchu
    Is there any free service to which I could send a UDP packet and it would respond telling me what is my "real" UDP port? (my application is behind a NAT) This kind of service could allow me to make a p2p coordination server with normal php hosting. The p2p clients would know their UDP ports from this service They will then contact my server over HTTP (which is what regular web hosting allows) and tell it their port (and ip, which is normally supplied to cgi scripts) My server will give the clients the IP addresses and ports of the other clients.

  • Trying to connect internally to Oracle, getting an idle instance?

    - by seanbseanbseanbseanb
    So I have an Oracle instance, and I know it's running on this system, I've su'd to the oracle user, and I'm trying to connect using "/ as sysdba". However, when I do connect, it says the instance is idle. I know the database is up and opened, because my application's talking to it. My paths (ORACLE_HOME, etc.) might be incorrect: any idea which incorrect setting might result in this? % sqlplus "/ as sysdba" SQL*Plus: Release 10.2.0.3.0 - Production on Mon Dec 8 09:23:22 2008 Copyright (c) 1982, 2006, Oracle.

  • Real world goods in iPhone app?

    - by Moshe
    I've seen questions asked here before, but they do not address the issue. That said: "In App Purchases" specifically may not be real world goods or services, according to Apple. What services allow integration with iPhone apps so that I can use ObjectiveC to sell things in an iPhone app?

  • Detect outgoing calls and problem with a real device

    - by Tobia Loschiavo
    Hi, I have a strange problem. To detect outgoing calls I have registered a broadcast receiver for android.intent.action.PHONE_STATE. When the state becomes OFFHOOK, then a conversation is started. It seems working on emulator: the debugger in fact reaches some code while it doesn't work on real device (Acer Liquid). Is it possible? Which is a way to detect outgoing calls? Thanks

  • Covariance and contravariance real world example

    - by Sir Psycho
    I'm having a little trouble understaing how I would use covariance and contravariance in the real world. So far, the only example's I've seen have been the same old array example. object[] objectArray = new string[] { "string 1", "string 2" }; It would be nice to see an example that would allow me to use it during my development if I could see it being used elsewhere. Can anyone point me to some useful resources?

  • Real-time spectrum analyzer with API

    - by bobobobo
    I'm looking for a C or C++ API that will give me real-time spectrum analysis of a waveform on Windows. I'm not entirely sure how large a sample window it should need to determine frequency content, but the smaller the better. For example, if it can work with a 0.5 second long sample and determine frequency content to the Hz, that would be wicked-awesome.

  • When using Oracle load balancing and ADO.NET, how do you know which host the command executed on?

    - by Leeks and Leaks
    It's possible to use Microsoft's OracleClient assembly to connect to an Oracle database, and using Oracle's connection string format, set it up to use load balancing, provided your Oracle environment supports it. The question I have is how do you know after the fact, which db host the command actually executed against? Is there a way to retrieve the machine name from the load balanced set of machines?

  • How does google-analytics guarantees that the tracking record is coming from the real site

    - by tuler
    When you sign up to google analytics it instructs you to use a javascript snippet on every page you want to track. This code includes an API key, which is visible to everyone who views your source code. How does it guarantees that the request is coming from the real site, and not from a third-party who wants to mess with your statistics? Does it check the HTTP Referer header? Even that is not safe, as it can be forged.

  • SQL to return the rownum of a specific row? (using Oracle db)

    - by jedierikb
    In Oracle 10g, I have this SQL: select dog.id as dogId from CANINES dog order by dog.codename asc which returns: id -- 204 203 206 923 I want to extend this query to determine the oracle rownum of a dog.id in this resultset. I have tried select rownum from (select dog.id as dogId from CANINES dog order by dog.codename asc) where dog.id=206 But this does not work out very well (it returns 1 no matter which dog.id I match on). I was expecting to get back 3. Thanks for your help! Notes http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html I am pretty sure I do not need to use rowid

    Are there any real stories about computer crime? I'm talking about stuff like in "Office Space", stealing fractions of pennies a couple of million times... Like that, only actual events.

Links or books for further reading please.

    - by rodrigoq
    Hello, I have to migrate this query (simplified here) from T-SQL to ORACLE SET IDENTITY_INSERT table ON INSERT INTO table (id, value) VALUES (1, 2) SET IDENTITY_INSERT table OFF id being an Identity field in SQLServer. I have the same table with a sequence in ORACLE, I couldn't find a snippet that shows how to disable the sequence and set it to start again with the MAX(id) + 1. Any ORACLE expert can help me with this? Thanks, Rodrigo.

  • How to insert result of mysql_real_escape_string() into oracle database?

    - by Prat
    For inserting special characters in data like (,')etc., I am using musql_real_escape_string() function & it's working fine. Now I want to use same variable while inserting values in Oracle. $str = 'N.G.Palace\'s Building', 'xyzcity', '12345678','India','100001',12 Here $str is result of mysql_real_escape_string(). so it escapes special character. Now my code for oracle is like this-: $qry ="INSERT INTO Ora_table(ship_to_street, ship_to_city,ship_to_country, ship_to_telephone, order_id, record_no) VALUES(".$str); So my doubt is Oracle is not accepting values return by mysql_real_escape_string i.e. Palace\'s (like this as this mysql function attach \ before 'single quote)? So can anybody tell me ho9w can I use that variable $str to insert data into Oracle? Also I tried like this also-: "q"."'"."c".$str."c"."'" can we use this for multiple values like in my case...though still I am unable to inser data in oracle? plz help.
