  • Any good idioms for error handling in straight C programs?

    - by Will Hartung
    Getting back in to some C work. Many of my functions look like this: int err = do_something(arg1, arg2, arg3, &result); With the intent the result gets populated by the function, and the return value is the status of the call. The darkside is you get something naive like this: int err = func1(...); if (!err) { err = func2(...); if (!err) { err = func3(...); } } return err; I could macro it I suppose: #define ERR(x) if (!err) { err = (x) } int err = 0; ERR(func1(...)); ERR(func2(...)); ERR(func3(...)); return err; But that only works if I'm chaining function calls, vs doing other work. Obviously Java, C#, C++ have exceptions that work very well for these kinds of things. I'm just curious what other folks do and how other folks do error handling in their C programs nowadays.

  • Singleton pattern with Web application, Not a good idea!!

    - by Tony
    Hi I found something funny, I notice it by luck while I was debugging other thing. I was applying MCP pattern and I made a singleton controller to be shared among all presentations. Suddenly I figured out that some event is called once at first postback, twice if there is two postback, 100 times if there is 100 postbacks. because Singleton is based on a static variable which hold the instance, and the static variable live across postbacks, and I wired the event assuming that it will be wired once, and rewired for each postback. I think we should think twice before applying a singleton in a web application, or I miss something?? thanks

  • What is a good way for a custom accessory view in a UITableViewCell to message the table view contro

    - by Alex Gosselin
    Hi Everyone, I am working on adding a custom accessory view, (a button) to a UITableViewCell, and I need it to tell the table view when it is touched, but I can't figure out how to communicate to the table view what button was pressed. Ideally I'd like to somehow call a function like this: [controller tableView:view didSelectCustomButtonAtIndexPath:indexPath usingCell:self]; when my custom view button is pressed. Sorry if this is a bit vague, I'm not really sure how to explain this well. I am basically looking for how to mimic the implementation for tableView:didSelectRowAtIndexPath: without having to subclass UITableViewCell. Thanks for any help.

  • Would Python make a good substitute for the Windows command-line/batch scripts?

    - by Lawrence Johnston
    I've got some experience with Bash, which I don't mind, but now that I'm doing a lot of Windows development I'm needing to do basic stuff/write basic scripts using the Windows command-line language. For some reason said language really irritates me, so I was considering learning Python and using that instead. Is Python suitable for such things? Moving files around, creating scripts to do things like unzipping a backup and restoring a SQL database, etc.

  • Where does code within Script tags go in the resulting AS class?

    - by Hanno Fietz
    I was wondering what happens to the code contained in an <mx:Script> tag. If I define a function tehre, it just becomes a member function of the generated class. But I noticed that it seems OK for the compiler if I just write some (static) method calls there (specifically, I call Font.registerFont()). I feel kind of guilty for doing this, because I have no idea what's really happening and when the code gets executed.

  • Are there any good Javascript/Jquery thumbnail script equivalents to TimThimb (PHP)?

    - by Mark
    For those unaware of TimThumb, it will take any image, of any size or dimension and create a thumbnail on the fly to any desired size. The beauty of it is that it really works on any dimension you feed it through a combination of either resizing the image, cropping or zoom cropping the image. Ive been searching for jscript equvalents but they either require the user to actually mask out the thumbs manually (looking for a script that automatically does it to images) or the scripts can't handle images in a different aspect ratio. Thanks for any leads on this!

  • Non-public application uses GPL code — are we obliged to publish our source?

    - by Cimbit
    Real Example. I have a closed source server-side program for "internal purposes only" (no distribution or selling). I want to use "MYSQL C++ Connector" in my server application in my VPS (MYSQL C++ Connector is GPL). Do I have to make my application "GPL" and distribute my source code? Can I use the GPL Source Code in my closed source application. (There is no distribution or selling of my application — it is for internal purposes only.)

  • Php exec() return code is -1 when in a forked process, but 0 in a normal script

    - by fb1
    I am using exec() inside a a script that runs as a daemon and forks child processes using the pear class Net_Server. I am getting a strange issue whereby the return code (the third param of of exec) comes back as -1. When I run the command on the command line, or with exec in a normal php script the return code is 0 as it should be. Anyone have any idea why this is happening, and how to fix it?

  • Separate "include" and "src" folders for application-level code?

    - by StackedCrooked
    This questions concerns mostly Unix/Linux style C++ development. I see that many C++ libraries store their header files in a "include" folder and source files in an "src" folder. For the sake of conformance I adopted this in my own code. But it is not clear to me whether this should be done for application code as well. I've seen a few cases where a flat directory structure is used for that. What would be the recommended approach?

  • How can I customize my layout.xml from code before calling setContentView(View) function?

    - by Marton_hun
    I would like to customize my layout definition (declared in my_layout.xml file) from code. Unfortunately I can use findViewById() function to find the specific views (defined in my_layout.xml file) and customize them from code only after I called setContentView(R.layout.my_layout). But what if I want to customize my layout first, before calling setContentView()? How can I access the specific views before calling setContentView()?

  • How do you get good line spacing with lpr?

    - by dan
    I'm using lpr with the following flags: lpr -o cpi=12 -o lpi=8 -o page-left=36 -o page-top=36 -o page-bottom=36 But the lines appear too close together. But if I decrease lpi to 6 or something, the font just gets taller. What I really want is control over the amount of space between the lines. My makeshift solution is to insert blank lines in the document using sed G, but ideally I would like to achieve 1.5 line spacing instead of full double-spaced. Is this possible?

  • Is there a static code analyzer [like Lint] for PHP files?

    - by eswald
    Is there a static code analyzer for PHP files? The binary itself can check for syntax errors, but I'm looking for something that does more, like unused variable assignments, arrays that are assigned into without being initialized first, and possibly code style warnings. Open-source programs would be preferred, but we might convince the company to pay for something if it's highly recommended.
