• Receiving SQL Server events from a CLR function

  - by Pablo Lerner

  I wrote a CLR class with several methods, which are linked as functions in a SQL Server 2005 database. When several of these functions are used in scope of one transaction or connection, I need another one to be automatically executed to clean up some stuff, at the time of transaction or connection close (either time is good for now, later I will decide which is best). I figure that receiving events from another new CLR functions can do, but I don't know how to achieve that. Can anyone point me to information on modules, documents or whatever, that can help me understand how to receive transaction or connection closing events in a CLR class, or how to execute a particular function when these events occur?

• .NET assembly in GAC + Config

  - by Dante

  I have a .NET 3.5 assembly, a DAL, that connects to a database through Linq2SQL. I deploy this assembly in the GAC as it can be used by multiple business layers. The question is: in a dev environment I have a connection string different than the one in the production environment. Before deploying the assembly to the prod GAC I need to recompile it with the appropriate connection string. Is there any way to allow deploying the assembly to the GAC independently of the connection string, being that info read from some config? Thx in advance

• Android DownloadManager - few questions

  - by ChrisR

  I have a few questions about the Android browser download manager . Does it support multiple downloads at the same time? From the code it looks like it does. What's advantage of using HTTPRequest over URL/URLConnection to download files? 3.The download manager opens and closes connection for each download. Is it the right thing to do? Or is it better to use the same connection for for all the download requests(by changing the required parameters) and then clse the connection?

• Is it ok to store large objects (java component for example) in an Application variable?

  - by DustMason

  I am developing an app right now which creates and stores a connection to a local XMPP server in the Application scope. The connection methods are stored in a cfc that makes sure the Application.XMPPConnection is connected and authorized each time it is used, and makes use of the connection to send live events to users. As far as I can tell, this is working fine. BUT it hasn't been tested under any kind of stress. My question is: Will this set up cause problems later on? I only ask because I can't find evidence of other people using Application variables in this way. If I weren't using railo I would be using CF's event gateway instead to accomplish the same task.

• stuck in while loop python

  - by user1717330

  I am creating a chat server in python and got quite far as a noob in the language. I am having 1 problem at the moment which I want to solve before I go further, but I cannot seem to find how to get the problem solved. It is about a while loop that continues.. in the below code is where it goes wrong while 1: try: data = self.channel.recv ( 1024 ) print "Message from client: ", data if "exit" in data: self.channel.send("You have closed youre connection.\n") break except KeyboardInterrupt: break except: raise When this piece of code get executed, on my client I need to enter "exit" to quit the connection. This works as a charm, but when I use CTRL+C to exit the connection, my server prints "Message from client: " a couple of thousand times. where am I going wrong?

Can anybody tell to me what gone wrong in my Java un-installation and how can I get back them.

• How to build a web service to detect content change(s) at an external website?

  - by Global nomad

  I'm researching ways to build a web service to periodically traverse a predetermined list of web pages (of another external website) to detect if a page's content has changed from editing of the page, and deletion of the page. The end goal is to have this web service post push-notification events to mobile devices. FYI, I've searched and read "Questions with similar titles" here. Thank you for sharing your answers.

• Alternate to control+drag to connect view element with file owner in xCode interface builder?

  - by yldave

  Working on an iPhone application through a TightVNC connection into a Mac Mini; the control+drag operation in Interface Builder to connect a view element to file owner doesn't work - I don't see the connecting line. It does work when I connect keyboard, mouse and monitor to the Mini and work on it directly, however it is a lot more convenient for me to run it through a VNC connection. Must be some quirk of the TightVNC connection that is preventing this. I tried different TightVNC settings for the cursor (let server handle it and so on) but no luck. Is there an alternative to control+drag to hook up outlets?

• ODBC - multiple connections from one app to the same data source

  - by Marcin K

  I vaguely remember reading somewhere (in MSDN ODBC documentation?) that one application cannot make more than one connection to a single data source. It seemed to me that I need one connection that all the threads of the application will have to share. I was trying to look this information up, but I can't seem to find it anymore. Does anyone know/remember how this works? It all might become a problem in our app, since some of its threads will dynamically connect to data sources of their choice. I don't want to see random connection errors if two of them will connect at the same time to one source, so I wanted to double check this info.

• Confusion using MYSQLI

  - by user1020069

  I just started using mysqli API for PHP. Apparently, every time an object of the class MYSQLI is instantiated, it can setup a connection to the database as it connects to the server unlike mysql_connect, which connects to the server first and then you are required to specify the database to query. Now this is a good problem if the db exists, in my case, the db does not exist on the first ever connection to the server/execution of the problem, hence I must connect without specifying the database, which is fine, since the msyqli constructor does not make this database mandatory. My challenge is essentially, how do I check if the database exists before attempting the first connection. The only way to really do this would be to establish a conection to the server and then use the result of the following query to gauge if the database exists: SELECT COUNT(*) AS `exists` FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMATA.SCHEMA_NAME="dbname" ; If this returns true, then the database exists, but now the challenge is how do I get the mysqli object to query this database rather than having to prefix the name of the database in the query. Thanks much

• WCF: What happens if a channel is established but no method is called?

  - by mafutrct

  In my specific case: A WCF connection is established, but the only method with "IsInitiating=true" (the login method) is never called. What happens? In case the connection is closed due to inactivity after some time: Which setting configures this timeout? Is there still a way for a client to keep the connection alive? Reason for this question: I'm considering the above case as a possible security hole. Imagine many clients connecting to a server without logging in thus preventing other clients from connecting due to bandwidth problems or port shortage or lack of processing power or ... Am I dreaming, or is this an actual issue?

• How to store a 250mb database in an Offline Web App

  - by Couto

  Ok, maybe i'm not seeing the whole picture or something, but i kinda need a brainstorm. So the purpose is to make a webapp (HTML5, CSS, Javascript) that has to search on a 250mb database without any internet connection, so.. yes the database has to be on the client side. The hard part here is, this App has to work on an iPod or iPhone without internet connection. (An initial connection to download the App is ok), LocalStorage has a 5mb limit, couchDB would be great since they have an webapp easily accessed by Javascript (privacy concerns don't matter at this point), so i'm pretty much out of ideas.... Does anyone see an alternative, or solution for the purpose?

• Updating .net 4.0 machine.config seems to have no effect

  - by Jon P

  I'm feeling stupid. I've just created my first ASP.net 4.0 site after working my way though over the years from 1.1 upwards. We have several settings at the machine.config level that I need to migrate to the new 4.0 machine.config. I though I had be adding the required connection strings to the connection string section of the following two files: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\machine.config C:\Windows\Microsoft.NET\Framework\v4.0.30319\machine.config When I created a new website in IIS and assigned it to the ASP.net 4.0 Application pool I only get the default LocalSqlServer connection string. I tried editing the name of this in the two files above to indicate which file it was in, but there was no change. Are there machine.config files in other locations I should be looking at?

• PreparedStatement and 'null' value in WHERE clause

  - by bond

  I am using PrepareStatement and BatchUpdate for executimg a UPDATE query. In for loop I create a Batch. At end of loop I execute batch. Above logic works fine if SQL query used in PrepareStatement does not have null values in WHERE claues. Update Statement fails if there is null value in WHERE clasue. My code looks something like this, connection = getConnection(); PreparedStatement ps = connection.prepareStatement("UPDATE TEST_TABLE SET Col1 = true WHERE Col2 = ? AND Col3 = ?") for (Data aa : InComingData) { if(null == aa.getCol2()) { ps.setNull(1, java.sql.Types.INTEGER); } else { ps.setInteger(1,aa.getCol2()) } if(null == aa.getCol3()) { ps.setNull(2, java.sql.Types.INTEGER); } else { ps.setInteger(2,aa.getCol3()) } ps.addBatch(); } ps.executeBatch(); connection.commit(); Any help would be appreciated.

• How do I create a create and execute an SQL command using OleDB directly?

  - by Pagis

  I want to use the OleDB interfaces directly to open a connection to a DB, create a command and executing it (for example using the ICommandText interface). The main thing I can't find is how to create the connection and the command object and how to connect the object that implements the ICommandText to the connection. In ADO I would just use the ActiveConnection property but I want to do this directly on the OleDB interfaces. Also, if anyone can recommend a tutorial to OleDB, ether online or a book, free or not that would be great (but a tutorial and not just a reference / API) I'm using C++ but any native code would be fine.
