  • What's best performance way to constantly change image on WP7?

    - by AlRodriguez
    I'm trying to make my own type of remote desktop for WP7. I have a WCF service that returns an image on what's on the target machine's screen. Here's the WCF Server Code: // Method to load desktop image Bitmap image = new Bitmap( ViewSize.Width, ViewSize.Height ); Graphics g = Graphics.FromImage( image ); g.CopyFromScreen( Position.X, Position.Y, 0, 0, ViewSize ); g.Dispose( ); return image; // Convert image to byte[] which is returned to client using ( MemoryStream ms = new MemoryStream( ) ) { Bitmap image = screenGrabber.LoadScreenImage( ); image.Save( ms, ImageFormat.Jpeg ); imageArray = ms.ToArray( ); } Here's the code for the WP7 client: MemoryStream stream = new MemoryStream( data ); BitmapImage image = new BitmapImage( ); image.SetSource( stream ); BackgroundImage.Source = image; The BackgroundImage variable is an Image control. I'm noticing this freeze on the emulator after a short while, and will eventually crash from an OutOfMemoryException. This is already pretty slow ( images show up a good half second later than what's on the screen ), and I'm wondering if there's a better/faster way of doing this? Any help would be great. Thanks in advance.

  • _REQUIREDNAME always nil

    - by Nali4Freedom
    I'm trying to use the method for naming a lua package after the filename mentioned here, however _REQUIREDNAME is never defined. For example I have these two files samplePackage.lua: print("_REQUIREDNAME: ", _REQUIREDNAME) return nil; packageTest.lua: require "samplePackage" And when I run packageTest.lua it outputs > _REQUIREDNAME: nil I also couldn't find any mention of _REQUIREDNAME in the Lua 5.1 Refrence manual, so was this removed from the language, or am I missing something?

  • Is `std::string(strerror(errno))` dangerous?

    - by StackedCrooked
    At some places in my code, I print debug messages like this: int ret = getLinkSpeed(device.getSysName(), linkSpeed); if (ret < 0) { logDebug("Failed to obtain port speed for this device. Error: " + std::string(strerror(errno))); } From the documentation it is not entirely clear if strerror will return 0 under certain conditions (which would cause my code to crash). Does anyone know if it's safe?

Though each time I grab this it is always going to change.

  • Is it wrong for a context (right click) menu be the only way a user can perform a certain task?

    - by Eric
    I'd like to know if it ever makes sense to provide some functionality in a piece of software that is only available to the user through a context (right click) menu. It seems that in most software I've worked with the right click menu is always used as a quick way to get to features that are otherwise available from other buttons or menus. Below is a screen shot of the UI I'm developing. The tree view on the right shows the user's library of catalogs. Users can create new catalogs, or add and remove existing catalogs to and from their library. Catalogs in their library can then be opened or closed, or set to read-only. The screen shot shows the context menu I've created for the browser. Some commands can be executed independently from any specific catalog (New, Add). Yet the other commands must be applied to a specifically selected catalog (Close, Open, Remove, ReadOnly, Refresh, Clean UP, Rename). Currently the "Catalog" menu at the top of the window looks identical to this context menu. Yet I think this may be confusing to the users as the tree view which shows the currently selected catalog may not always be visible. The user may have switched to the Search or Filters tab, or the left pane may be hidden entirely. However, I'm hesitant to change the UI so that the commands that depends on a specifically selected catalog are only available through the context menu.

  • Python | How to append elements to a list randomly

    - by MMRUser
    Is there a way to append elements to a list randomly, built in function ex: def random_append(): lst = ['a'] lst.append('b') lst.append('c') lst.append('d') lst.append('e') return print lst this will out put ['a', 'b', 'c', 'd', 'e'] But I want it to add elements randomly and out put something like this: ['b', 'd', 'b', 'e', 'c'] And yes there's a function random.shuffle() but it shuffles a list at once which I don't require, I just want to perform random inserts only.

  • Python 3.2: How to pass a dictionary into str.format()

    - by Robert Dailey
    I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem. Here is what I'm trying to do: stats = { 'copied': 5, 'skipped': 14 } print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) ) The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?

  • Invoking a function of library libfprint in Python

    - by Ivanelson
    I need help to call a function(Struct C) that detects the devices, so I'm calling the function this way: from ctypes import * fp = CDLL('./libfprint.so.0') fp.fp_discover_devs.argtypes = None fp.fp_discover_devs.restype = c_char_p ret = fp.fp_discover_devs() print ret # is "0" That is not detected any device, because the return is "0". See the documentation of the function: I'm using Ubuntu and I downloaded the "fprint_demo" and works perfectly. Did you install any package missing? Thanks.

  • NZEC in spoj FACKT

    - by frodo
    I was trying to solve this problem http://www.spoj.pl/problems/FACKT/, and I keep getting a Non-Zero Exit Code (NZEC). How exactly do I figure out what to change in the code to overcome this? Here is the code import math import sys def cal_num(n): i = 1 f = 1 while f<n: f *= i i = i + 1 return i-1 while 1: line = sys.stdin.readline() if line == "": break n = int(line) x = cal_num(n) y = math.factorial(2*x) l = int(math.ceil(math.log(y,10))) print (x,l) Any suggestion would be welcome.

  • Eclipc java,writting a program [closed]

    - by ghassar
    I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

  • Thousands separator in .Net/F#

    - by rwallace
    What's the recommended way to print an integer with thousands separator? Best I've come up with so far is let thousands(x:int64) = String.Format("{0:0,0}", x) Which works in most cases, but prints zero as 00.
