• Handling apostrophes, php and pgsql

  - by running4surival

  For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

• Can I set the default value of a custom list column to be a new Guid?

  - by Graeme

  I tried setting the defaultvalue property of the field to Guid.NewGuid() but every item created has the same guid so I guess the Guid.NewGuid() is being stored as the default rather than being run each time. Is the only way to achieve this to add an event handler to the list for OnAdded?

• Sequential (comb) GUIDs for Oracle

  - by Eyvind

  We are in the process of switching from the C# Guid.NewGuid() random-ish guid generator to the sequential guid algorithm suggested in this post. While this seems to work well for MS SQL Server, I am unsure about the implications for Oracle databases, in which we store guids in a raw(16) field. Does anyone have any insight as to whether this algorithm would be good for creating sequential guids for Oracle as well as for MS SQL Server, or if a different variant should be used. Thanks!

• how to deal with the position in a c# stream

  - by CapsicumDreams

  The (entire) documentation for the position property on a stream says: When overridden in a derived class, gets or sets the position within the current stream. The Position property does not keep track of the number of bytes from the stream that have been consumed, skipped, or both. That's it. OK, so we're fairly clear on what it doesn't tell us, but I'd really like to know what it in fact does stand for. What is 'the position' for? Why would we want to alter or read it? If we change it - what happens? In a pratical example, I have a a stream that periodically gets written to, and I have a thread that attempts to read from it (ideally ASAP). From reading many SO issues, I reset the position field to zero to start my reading. Once this is done: Does this affect where the writer to this stream is going to attempt to put the data? Do I need to keep track of the last write position myself? (ie if I set the position to zero to read, does the writer begin to overwrite everything from the first byte?) If so, do I need a semaphore/lock around this 'position' field (subclassing, perhaps?) due to my two threads accessing it? If I don't handle this property, does the writer just overflow the buffer? Perhaps I don't understand the Stream itself - I'm regarding it as a FIFO pipe: shove data in at one end, and suck it out at the other. If it's not like this, then do I have to keep copying the data past my last read (ie from position 0x84 on) back to the start of my buffer? I've seriously tried to research all of this for quite some time - but I'm new to .NET. Perhaps the Streams have a long, proud (undocumented) history that everyone else implicitly understands. But for a newcomer, it's like reading the manual to your car, and finding out: The accelerator pedal affects the volume of fuel and air sent to the fuel injectors. It does not affect the volume of the entertainment system, or the air pressure in any of the tires, if fitted. Technically true, but seriously, what we want to know is that if we mash it to the floor you go faster..

• RUP (Rational Unified Process)

  - by tony

  I have chosen to use the development method RUP (Rational Unified Process) in my project. This is a method I've never used before. I've also included some elements from Scrum in the development process. The question is what the requirement specifications should contain in a RUP-model? Is it functional and non-functional requirements? And what should be included in a technical analysis and security requirements for RUP? Can’t find any information. Notes about this would be helpful. Hope people with RUP experience can share some useful experiences

• Would it be faster to use CMS for building the first site in ASP.NET?

  - by rem

  I need an opinion and advise from experienced ASP.NET people, what way to go. Assuming that a developer has some practical background with HTML/JavaScript/PHP on one side and some .NET/C#/WPF experience on the other side. No previous hands on experience with ASP.NET - only theory and some read books on the topic. The task is to build ASP.NET web site with User Managment functionality (user authentication, user account, user buying history, user points and so on) and E-commerce functionality with shopping cart, checkout and all needed for this. Is it worth, i.e. will it be faster, more reliable and secure in the result to use a ASP.NET CMS system (for example Sitefinity from Telerik as declared developer friendly) to build such first site? In what case the learning curve will be more steep and it will take more time to achieve similar results? Notes to take into consideration: 1) Price of the CMS matters not very much 2) E-commerce module should be written from scratch in any case (and integrated in case of using CMS) due to very specific requirements

• Saving order of a List in JPA

Can you show me a way to deal with this problem? P.S. There is not a field in the entities that I put in the collections by which I can order them. Rosen

• Autocomplete functionality on a textarea

  - by sslepian

  Is there a way to implement auto-complete functionality in a region defined by textarea tags or something similar? I'm currently using a jquery autocomplete plugin to suggest input to the user inside input tags, but the issue is that the autocomplete phrases can often be fairly long and thus scroll off the edge of the input field.

• Disable animations when ending search in iPhone

  - by camilo

  Hi. A quicky: is there a way to dismiss the keyboard and the searchDisplayController without animation? I was able to do it when the user presses "Cancel", but when the user presses the black "window thingy" above search field (only visible while the user hasn't inserted any text), the animation always occurs, even when I change the delegate functions. Is there a way to control this, or as an alternative, to disable the user to end searching by pressing the black window? Thanks in advance.
