  • Creating a structure from bytes with ctypes and IronPython

    - by Adal
    I have the following CPython code which I now try to run in IronPython: import ctypes class BarHeader(ctypes.Structure): _fields_ = [ ("id", ctypes.c_char * 4), ("version", ctypes.c_uint32)] bar_file = open("data.bar", "rb") header_raw = bar_file.read(ctypes.sizeof(BarHeader)) header = BarHeader.from_buffer_copy(header_raw) The last line raises this exception: TypeError: expected array, got str I tried BarHeader.from_buffer_copy(bytes(header_raw)) instead of the above, but then the exception message changes to TypeError: expected array, got bytes. Any idea what I'm doing wrong?

I get no error message and it only shows html code in the "Design View". I've tried reinstalling VS2008 and BIDS, but hasn't worked. This was all working when I last used it 2 weeks ago. -nate

  • How do I recover from an unchecked exception?

    - by erickson
    Unchecked exceptions are alright if you want to handle every failure the same way, for example by logging it and skipping to the next request, displaying a message to the user and handling the next event, etc. If this is my use case, all I have to do is catch some general exception type at a high level in my system, and handle everything the same way. But I want to recover from specific problems, and I'm not sure the best way to approach it with unchecked exceptions. Here is a concrete example. Suppose I have a web application, built using Struts2 and Hibernate. If an exception bubbles up to my "action", I log it, and display a pretty apology to the user. But one of the functions of my web application is creating new user accounts, that require a unique user name. If a user picks a name that already exists, Hibernate throws an org.hibernate.exception.ConstraintViolationException (an unchecked exception) down in the guts of my system. I'd really like to recover from this particular problem by asking the user to choose another user name, rather than giving them the same "we logged your problem but for now you're hosed" message. Here are a few points to consider: There a lot of people creating accounts simultaneously. I don't want to lock the whole user table between a "SELECT" to see if the name exists and an "INSERT" if it doesn't. In the case of relational databases, there might be some tricks to work around this, but what I'm really interested in is the general case where pre-checking for an exception won't work because of a fundamental race condition. Same thing could apply to looking for a file on the file system, etc. Given my CTO's propensity for drive-by management induced by reading technology columns in "Inc.", I need a layer of indirection around the persistence mechanism so that I can throw out Hibernate and use Kodo, or whatever, without changing anything except the lowest layer of persistence code. As a matter of fact, there are several such layers of abstraction in my system. How can I prevent them from leaking in spite of unchecked exceptions? One of the declaimed weaknesses of checked exceptions is having to "handle" them in every call on the stack—either by declaring that a calling method throws them, or by catching them and handling them. Handling them often means wrapping them in another checked exception of a type appropriate to the level of abstraction. So, for example, in checked-exception land, a file-system–based implementation of my UserRegistry might catch IOException, while a database implementation would catch SQLException, but both would throw a UserNotFoundException that hides the underlying implementation. How do I take advantage of unchecked exceptions, sparing myself of the burden of this wrapping at each layer, without leaking implementation details?

  • Does Restlet support parsing URLs into calling methods with parameters?

    - by John C
    Take the following example. I have a resource public class HelloWorldResource extends ServerResource { @Get public String represent(String arg) { return "hello, world (from the cloud!)" + arg; } } That is mapped by router.attach("/hi/{message}", HelloWorldResource.class); Is it possible to configure the routing such that accessing /hi/somestuffhere will make restlet fill in the arg parameter in the represent method?

    Tried to install some program, it gives above message requiring 1.1.4322. BUT as the title says, all the frameworks are already installed on my WinXP SP2, if i inspect C:\WINDOWS\Microsoft.NET\Framework\ The machine has VS2008 which essentially required full installtion of Framework 3.5 SP1. Any ideas? (i know, just re-install framework 1.1 again, but why should i - I can see all Frameworks are installed, and things are supposed to be backward compatible.

  • ASP.NET mvc 2 Validation always shows errors on initial page load.

    - by gt124
    I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it? Thanks in advance.

  • High-level languages for out-of-the-box GUI desktop application programming

    - by Omeoe
    After I discontinued programming in C++ while entering into web authoring I was spoilt by PHP's high level constructs like hash tables or its dynamic, weak typing. I remembered the angst of C/C++ pointers and the maze of low-level Win32 API handles and message loops and that prevented me from utilizing environments like Code::Blocks for desktop applications. I am also not very fond of bulky, statically-typed C#/.NET environment. Any other ideas?
