  • Optional Argument: compile time constant issue

    - by Jack
    Why is this working: public int DoesEmailAddressExistsExcludingEmailAddressID( string emailAddress, string invitationCode, int emailAddressID = 0, int For = (int) Enums.FOR.AC) whereas this doesn't public int DoesEmailAddressExistsExcludingEmailAddressID( string emailAddress, string invitationCode, int emailAddressID = 0, int For = Enums.FOR.AC.GetHashCode()) where AC is enum. Can enums's hashcode change at runtime?

  • Iphone & Web App synch

    - by Jack Welsh
    I am trying to build an Iphone App client for our CRM solution so our sales people would be able to access the information available in our CRM through an Iphone App. I am trying to find out what is the recommended approach to architect the application when it comes to the database. I am not sure where should the data reside, should I save a subset of the data on the iPhone, or should I just rely on webservices and pull the information I need from the database whenever I need it. Also, is there any best practices or frameworks to build such applications on the Iphone.

    - by jack
    I want to verify that the HTML tags present in a source string are also present in a target string. For example: >> source = '<em>Hello</em><label>What's your name</label>' >> verify_target(’<em>Hi</em><label>My name is Jim</label>') True >> verify_target('<label>My name is Jim</label><em>Hi</em>') True >> verify_target('<em>Hi<label>My name is Jim</label></em>') False

  • How to play the sound of an object sliding on another object for a variable duration

    - by Antoine
    I would like to add sound effects to a basic 2D game. For example, a stone sphere is rolling on wood surface. Let's say I have a 2 second audio recording of this. How could I use the sample to add sound for an arbitrary duration ? So far I have two solutions in mind: a/ record the sound for an amount of time that is greater than the maximum expected duration, and play only a part of it; b/ extract a small portion of the sample and play it in a loop for the duration of the move; however I'm not sure if it makes sense with an audio wave.

  • SDL_ttf and Numbers (int)

    - by jack moore
    int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, fixedscore, fColor ); ^^ This doesn't work - looks like fixedscore is empty or doesn't exists. int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, "Works fine", fColor ); ^^ Works fine, but... I guess converting int to char* doesn't really work. So how do you print scores in SDL? Oh and one more thing: why is the text so ugly? Any help would be appreciated. Thanks.

  • JavaScript (SVG drawing): Positioning x amount of points in an area

    - by Jack
    I'm using http://raphaeljs.com/ to try and draw multiple small circles. The problem I'm having is that the canvas has a fixed width, and if I want to draw, say, 1000 circles, they don't wrap onto a 'new line' (because you have to specify the xy position of each circle). E.g. I want this: .................................................. to look like this: ............................ ...................... At the moment I'm doing this: for ( var i = 0; i < 1000; i++ ) { var multiplier = i*3; if ( i <= 50 ) { paper.circle((2*multiplier),2,2); } else if ( i >= 51 && i <= 101 ) { paper.circle((2*multiplier) - 304,8,2); } else if ( i >= 152 && i <= 202 ) { paper.circle((2*multiplier) - 910,14,2); } } For reference: circle(x co-ord, y co-ord, radius) This is messy. I have to add an if statement for every new line I want. Must be a better way of doing it..?

  • How to mount an ISO image as if it were a physical CD?

    - by Michael Robinson
    I have an ISO backup of a beloved game from my youth. I with to relive those better times by listening to game's soundtrack. Is there a way for me to mount said ISO in such a way that I can rip the audio tracks into mp3 files? I ask because although I can successfully mount the ISO, ripit / abcde report no cd inserted. How I mounted the ISO: sudo mount -t iso9660 -o loop iso.iso /media/ISO Alternatively is there another way to recover audio from ISO images?

  • C# XAML get new width and height for Canvas

    - by Jack Navarro
    I have searched through many times but have not seen this before. Probably really simple question but can't wrap my head around it. Wrote a VSTO add-in for Excel that draws a Grid dynamically. Then launches a new window and replaces the contents of the Canvas with the generated Grid. The problem is with printing. When I call the print procedure the canvas.height and canvas.width returned is the old value prior to replacing it with the grid. Sample: string="<Grid Name=\"CanvasGrid\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">..Lots of stuff..</Grid>"; // Launch new window and replace the Canvas element WpfUserControl newWindow = new WpfUserControl(); newWindow.Show(); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 StringReader stringReader = new StringReader(LssAllcChrt); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas myCanvas = newWindow.FindName("GrphCnvs") as Canvas; myCanvas.Children.Clear(); myCanvas.Children.Add((UIElement)XamlReader.Load(xmlReader)); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 but should be much larger the Grid spans all three of my screens Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens //Run code from WpfUserControl.cs after it loads from button click Grid testGrid = canvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens So basically I have no way of telling what my new width and height are Any Ideas

  • Constructor and Destructors in C++ [Not a question] [closed]

    - by Jack
    I am using gcc. Please tell me if I am wrong - Lets say I have two classes A & B class A { public: A(){cout<<"A constructor"<<endl;} ~A(){cout<<"A destructor"<<endl;} }; class B:public A { public: B(){cout<<"B constructor"<<endl;} ~B(){cout<<"B destructor"<<endl;} }; 1) The first line in B's constructor should be a call to A's constructor ( I assume compiler automatically inserts it). Also the last line in B's destructor will be a call to A's destructor (compiler does it again). Why was it built this way? 2) When I say A * a = new B(); compiler creates a new B object and checks to see if A is a base class of B and if it is it allows 'a' to point to the newly created object. I guess that is why we don't need any virtual constructors. ( with help from @Tyler McHenry , @Konrad Rudolph) 3) When I write delete a compiler sees that a is an object of type A so it calls A's destructor leading to a problem which is solved by making A's destructor virtual. As user - Little Bobby Tables pointed out to me all destructors have the same name destroy() in memory so we can implement virtual destructors and now the call is made to B's destructor and all is well in C++ land. Please comment.

  • Multithreading in PHP

    - by Jack
    I am working on windows. I am building a twitter application which periodically checks for new tweets as well as allows users to update their status. I have written separate PHP files for reading (reader.php) and writing tweets (writer.php). The only problem is how do I periodically read the tweets. There are a few ways which I can think of - 1) Use a time-based job scheduler (like Cron) to periodically run the reader.php. How do I do this? 2) Use multithreading to run both reader and writer.php and use a timer function in reader.php Suggestions?

  • Not able to pass multiple override parameters using nose-testconfig 0.6 plugin in nosetests

    - by Jaikit
    Hi, I am able to override multiple config parameters using nose-testconfig plugin only if i pass the overriding parameters on commandline. e.g. nosetests -c nose.cfg -s --tc=jack.env1:asl --tc=server2.env2:abc But when I define the same thing inside nose.cfg, than only the value for last parameter is modified. e.g. tc = server2.env2:abc tc = jack.env1:asl I checked the plugin code. It looks fine to me. I am pasting the part of plugin code below: parser.add_option( "--tc", action="append", dest="overrides", default = [], help="Option:Value specific overrides.") configure: if options.overrides: self.overrides = [] overrides = tolist(options.overrides) for override in overrides: keys, val = override.split(":") if options.exact: config[keys] = val else: ns = ''.join(['["%s"]' % i for i in keys.split(".") ]) # BUG: Breaks if the config value you're overriding is not # defined in the configuration file already. TBD exec('config%s = "%s"' % (ns, val)) Let me know if any one has any clue.

  • choppy sound with random popping 13.04

    - by Goddard
    I was hoping some one could help me figure out why my audio is popping randomly. I just got some new speakers and it was popping previously, but I was using monitor speakers so it wasn't really noticeable. Now I have some Bose speakers hooked up via an analog cable. It is not the speakers because my Android phone plays audio fine. When I open the sound settings window the popping happens at exactly the same time a third sound device is displayed very quickly and then disappears. This keeps happening at about 30 second intervals. Any help is appreciate. If you need more details just let me know how to get them.

  • Why have mp3 files ripped with Lame always have 128 kbit/s irrespect of settings?

    - by Takkat
    Using Sound Juicer I am able to rip Cds very conveniently. I would like to rip them in about 256 kbit/s variable bitrate. To accomplish this I have defined the settings for mp3 in gnome-audio-profiles-properties as follows: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr-quality=0 ! id3v2mux where vbr-quality=0 should give me a variable bitrate averaging 245 kbit/s. The resulting files however always say they are in 128 kbit/s. Is this only a tagging bug or is indeed the bitrate that low? How could I find out?

  • Forcing deallocation of large cache object in Java

    - by Jack
    I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java? I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..

  • Rewrite a URL that's already been redirected?

    - by Jack
    Hi guys, I'm running an Apache2 web server with a dynamic IP address. I bought exampledomain.net, and I use no-ip.com's domain-update service to redirect any visitors to my current ip address (endnote #1). For example, someone visits exampledomain.net and they get redirected to 73.181.57.34. It works like a charm. However, it isn't all that user-friendly. Can I rewrite the redirected, ip-address URL? I tried these rewrite rules in the root folder's .htaccess... RewriteEngine On RewriteCond %{HTTP_HOST} ^73\.181\.57\.34:88 RewriteRule ^(.*)$ http://www.exampledomain.net/$1 [L,NC] # I simplified the RewriteCond. I would use regex in a real situation. Of course, this creates an infinite loop. The user visits www.exampledomain.net. They're redirected to 73.181.57.34:88 by no-ip. Apache redirects them to www.exampledomain.net which redirects them back to 73.181.57.34:88... so on and so forth. I'm a noob when it comes to rewriting, but is there a way to rewrite a URL without redirecting? I tried these rewrite rules too (a shot in the dark)... RewriteEngine On RewriteCond %{HTTP_HOST} ^73\.181\.57\.34:88 RewriteRule ^(.*)$ my.exampledomain.net/$1 [L,NC] # I'd read that Apache replied with a redirect header when you include http Thanks! (1) No-IP works like this: You download and install their dynamic update client on your server. Every couple of minutes it polls your server for its current external ip address. If it's changed, it updates your server's ip address in no-ip's records.

  • Variable width columns in a table

    - by Jack
    I'm using an HTML table for a calendar and I want to fill the cells with various events from my database. Usually they will land on weekends but some will run for long weekend, bank holidays or even the odd week day. How can I get my tables columns to expand and shrink accordingly. I'd like to avoid the use of javascript if possible. If this can't be done I'm going to need a tutorial to help me get my head around how to make div's positioning behave. cheers
