• Take data from an XML file and put it into a MySQL database

  - by Aidan

  Hi Guys, I'm looking to construct a script that would go through an XML file. Would find specific tags in it, put them in a table and fill the table with specific tags within them. I'm using MySQL 5.1 so loadXML isn't an option and I think that ExtractData() method wont be much use either.. but I don't really know. What would be the best way to go about this?

• Random number from a range in a Bash Script

  - by Jack

  Hi, I need to generate a random port number between 2000-65000 from a shell script. The problem is $RANDOM is only a 16bit number, so im stuck! PORT=$(($RANDOM%63000+2001)) would work nicely if it wasn't for the size limitation. Does anyone have an example of how I can do this, maybe by extracting something from /dev/urandom and getting it within a range? Thanks.

• Using pragma once in a C++ project in Xcode 4

  - by Nils

  I know that #pragma once is non-standard, however it is supported by most compilers. So on my Mac I can compile C++ code with headers that use #pragma once on the command line using clang++. The strange thing however is that it does not seem to work within Xcode. I get Invalid preprocessing directive when I try to use #pragma once. I am using the newest version of OSX (10.8.2) and Xcode (Version 4.5.1 (4G1004)).

• How can I "merge" or "flatten" results from a query which returns multiple rows into a single result

  - by dsm

  I have a simple query over a table, which returns results like the following: id id_type id_ref 2702 5 31 2702 16 14 2702 17 3 2702 40 1 2702 26 4 And I would like to merge the results into a single row, for instance: id concatenation 2702 5,16,17,40,26:31,14,3,1,4 Is there any way to do this within a trigger? NB: I know I can use a cursor, but I would really prefer not to unless there is no better way.

  - by AlexFreitas

  Is it possible to have a connection to LotusNotes and use it as a data source for a C# project? We use LN for email/calendar. Management wants a web page that would interact with the calendar. I think this can all be done within Notes, but I would much rather do it in .NET. Some very specific functionality is wanted, some of which I'm not really sure can even be done in Notes.

• How to reference a class that implements certain interface?

  - by vikp

  Hi, I have an interface for logging the exceptions, i.e. IExceptionLogger. This interface has 3 implementations: DBExceptionLogger, XMLExceptionLogger, CSVExceptionLogger. I have an application that will make a use of DBExceptionLogger. The application references only IExceptionLogger. How do I create an instance of DBExceptionLogger within the application. I can't reference the DBExceptionLogger directly since it will break the purpose of having IExceptionLogger interface. Thanks
