  • Spark show logged in user

    - by Jose
    How do I show the username of the person logged in within a Spark View? The default MVC view engine had a Page object that you could get the info from. How would I do that in spark? I know that I could put the info into the viewdata dictionary, which is probably the best, but I don't want to have to write ViewData["User"] = myUser; before I return from EVERY action method. I'd like some feedback

  • Registering a COM control during installation

    - by Curtis
    One of our applications needs to register a COM control during installation. If a newer version of that control is already registered, we don't want to overwrite it with the older. What are the Windows MSI install conditions I would user to control this? Or is there some other 'best-practice' method I'm not aware of? Thanks

  • two UserControls, one page, need to notify each other of updates

    - by jeriley
    I've got a user control thats used twice on the same page, each have the ability to be updated (a dropdown list gets a new item) and I'm not sure what might be the best way to handle this. One concern - this is an older system (~4+ years, datasets, .net2) and it is amazingly brittle. I did manage to have it run on 3.5 with no problems, but I've had a few run-ins with the javascript validation (~300 lines per page) throwing up all over the place when I change/add/modify controls in the parent.

  • When to use std::size_t?

    - by nhaa123
    Hi, I'm just wondering should I use std::size_t for loops and stuff instead of int? For instance: #include <cstdint int main() { for (std::size_t i = 0; i < 10; ++i) // std::size_t OK here? Or should I use, say, unsigned int instead? } In general, what is the the best practice regarding when to use std::size_t?

  • Composite Views and View Controllers

    - by BillyK
    Hi, I'm somewhat new to Android and am in the process of designing an application with a couple fairly complex views. One of the views is intended to involve a complex view displaying information associated with model objects and segregated into several different views; the navigation of which is meant to be achieved using sliding effects (i.e. sliding one's finger across the screen to traverse from one screen to the next, etc). The view itself will be used to host multiple sets of views for varying types of model objects, but with a general structure that is reused between them all. As a rough example, the view might come up to display information about a person (the model object), displaying several details views: a view for general information, a view displaying a list of hobbies, and a view displaying a list of other individuals associated with their social network. The same general view, when given a model object representing a particular car would give several different views: A general view with details, A view containing photo images for that vehicle, a view representing locations which it could be purchased from, and a view providing a list of related cars. (NOTE: This is not the real data involved, but is representative of the general intent for the view). The subviews will NOT cover the entire screen real-estate and other features within the view should be both visible and able to be interacted with by the user. The idea here is that there is a general view structure that is reusable and which will manage a set of subviews dynamically generated based upon the type of model object handed to the view. I'm trying to determine the appropriate way to leverage the Android framework in order to best achieve this without violating the integrity of the framework. Basically, I'm trying to determine how to componentize this larger view into reusable units (i.e. general view, model-specific sub-view controllers, and individual detail views). To be more specific, I'm trying to determine if this view is best designed as a composite of several custom View classes or a composite of several Activity classes. I've seen several examples of custom composite views, but they typically are used to compose simple views without complex controllers and without attention to the general Activity lifecycle (i.e. storing and retrieving data related to the model objects, as appropriate). On the other hand, the only real example I've seen regarding a view comprised of a composite of Activities is the TabActivity itself, and that isn't customizable in the fashion that would be necessary for this. Does anyone have any suggestions as to the appropriate way to structure my view to achieve the application framework I'm looking for? Views? Activities? Something else? Any guidance would be appreciated. Thanks in advance.

  • Writing multiple NSData to File

    - by user326943
    I need a hint on how to write multiple NSData chunks to single file. Downloading a file using NSURLConnection in chunks. Each chunk is downloaded in a separate NSOperation thread. As the chunks finish downloading they need to be written to a file so combined result is the file downloaded. What would be the best way to manage the NSData that is returned and writing it to a single file?

  • Getting a specific bit value in a byte string

    - by ignoramus
    There is a byte at a specific index in a byte string which represents eight flags; one flag per bit in the byte. If a flag is set, its corresponding bit is 1, otherwise its 0. For example, if I've got b'\x21' the flags would be 0001 0101 # Three flags are set at indexes 3, 5 and 7 # and the others are not set What would be the best way to get each bit value in that byte, so I know whether a particular flag is set or not? (Preferably using bitwise operations)

  • Queuing methods to be run on an object by different threads in Python

    - by Ben
    Let's say I have an object who's class definition looks like: class Command: foo = 5 def run(self, bar): time.sleep(1) self.foo = bar return self.foo If this class is instantiated once, but different threads are hitting its run method (via an HTTP request, handled separately) passing in different args, what is the best method to queue them? Can this be done in the class definition itself?

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • What is the most effective way to test for combined keyboard arrow direction in ActionScript 3.0?

    - by Relee
    I need to monitor the direction a user is indicating using the four directional arrow keys on a keyboard in ActionScript 3.0 and I want to know the most efficient and effective way to do this. I've got several ideas of how to do it, and I'm not sure which would be best. I've found that when tracking Keyboard.KEY_DOWN events, the event repeats as long as the key is down, so the event function is repeated as well. This broke the method I had originally chosen to use, and the methods I've been able to think of require a lot of comparison operators. The best way I've been able to think of would be to use bitwise operators on a uint variable. Here's what I'm thinking var _direction:uint = 0x0; // The Current Direction That's the current direction variable. In the Keyboard.KEY_DOWN event handler I'll have it check what key is down, and use a bitwise AND operation to see if it's already toggled on, and if it's not, I'll add it in using basic addition. So, up would be 0x1 and down would be 0x2 and both up and down would be 0x3, for example. It would look something like this: private function keyDownHandler(e:KeyboardEvent):void { switch(e.keyCode) { case Keyboard.UP: if(!(_direction & 0x1)) _direction += 0x1; break; case Keyboard.DOWN: if(!(_direction & 0x2)) _direction += 0x2; break; // And So On... } } The keyUpHandler wouldn't need the if operation since it only triggers once when the key goes up, instead of repeating. I'll be able to test the current direction by using a switch statement labeled with numbers from 0 to 15 for the sixteen possible combinations. That should work, but it doesn't seem terribly elegant to me, given all of the if statements in the repeating keyDown event handler, and the huge switch. private function checkDirection():void { switch(_direction) { case 0: // Center break; case 1: // Up break; case 2: // Down break; case 3: // Up and Down break; case 4: // Left break; // And So On... } } Is there a better way to do this?

    I need to be able to make a program that looks through a mailbox of bounced messages, where the messages come back with the initial message in a .msg attachment, and open the .msg attachment for processing in ASP.NET 2.0. Is there any sort of code that might help in this? I've been looking at http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c as a starting point, but can't figure out how best to open the attachment from there, or if there's some easier way I'm missing.
