  • Need to make sure value is within 0-255

    - by igor
    This is probably really easy, but I'm lost on how to "make sure" it is in this range.. So basically we have class Color and many functions to implement from it. this function I need is: Effects: corrects a color value to be within 0-255 inclusive. If value is outside this range, adjusts to either 0 or 255, whichever is closer. This is what I have so far: static int correctValue(int value) { if(value<0) value=0; if(value>255) value=255; } Sorry for such a simple question ;/

  • Background image of table cell

    - by Shuaib
    Hey guys, Trying to set a background image for a table view cell, tried almost everything but failing. Hoping someone would notice what I am doing wrong. Here is how my current code looks like: static NSString *CustomCellIdentifier = @"listCustomCell"; listCustomCell *cell = (listCustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"listCustomCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[listCustomCell class]]) cell = (listCustomCell *)oneObject; } cell.backgroundColor = [UIColor clearColor]; UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_selected.png"]]; //[cell setBackgroundView:backgroundImageView]; cell.backgroundView = backgroundImageView; The image won't show up in the background of the cell. All I see is plain white background. Thanks for help.

  • Need help using the Windows IP Helper API & ParseNetworString in C#.

    - by JohnnyNoir
    I'm attempting to rewrite some C# web service code that uses the Windows IP Helper API call "SendARP" to retreive a remote system's MAC address. SendARP works great - until you cross a network segment as Arp requests aren't routed. I've been looking at the "ParseNetworkString" documentation after happening across its existance on StackOverflow. The quick & dirty algorithm I have in mind is: public static string GetMacAddress(string strHostOrIP) { if (strHostOrIP is IPAddress) { parse results of nbstat -A strHostOrIP return macAddress } if (strHostOrIP is Hostname) { IPHostEntry hostEntry = null; try { hostEntry = Dns.GetHostEntry(strHostOrIP); } catch { return null; } if (hostEntry.AddressList.Length == 0) { return null; } foreach (IPAddress ip in hostEntry.AddressList) { if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) { ipAddress = ip; break; } } } return GetMACAddress(ipAddress); } "ParseNetworkString" is new with Vista/Win2008 so I haven't been able to find example C# code demonstrating its use and I'm no C++ coder so if anyone can point me in the right direction...

  • ag_e_parser_bad_property_value Silverlight Binding Page Title

    - by zXynK
    XAML: <navigation:Page ... Title="{Binding Name}"> C# public TablePage() { this.DataContext = new Table() { Name = "Finding Table" }; InitializeComponent(); } Getting a ag_e_parser_bad_property_value error in InitializeComponent at the point where the title binding is happening. I've tried adding static text which works fine. If I use binding anywhere else eg: <TextBlock Text="{Binding Name}"/> This doesn't work either. I'm guessing it's complaining because the DataContext object isn't set but if I put in a break point before the InitializeComponent I can confirm it is populated and the Name property is set. Any ideas?

  • MySql UDF using shared library won't load

    - by Jarrod
    I am attempting to create a mysql UDF which will match a fingerprint using Digital Persona's free linux SDK library. I have written a trivial UDF as a learning experience which worked fine. However, when I added a dependency to Digital Persona's shared object I can no longer get MySql to load my UDF. I added includes to DP's headers and compiled my UDF using: gcc -fPIC -Wall -I/usr/src/mysql-5.0.45-linux-i686-icc-glibc23/include -shared -o dp_udf.so dp_udf.cc I also tried adding the -static argument, but whenever I restart MySql, I get the error: Can't open shared library 'dp_udf.so' (errno: 0 /usr/local/mysql/lib/plugin/dp_udf.so: undefined symbol: MC_verifyFeaturesEx) MC_verifyFeaturesEx is a function defined "dpMatch.h" which I included, and is implemented in libdpfpapi.so which I have tried placing in the same location as my dp_udf.so and in /usr/lib. Am I doing something wrong with my call to gcc (my C++ skills are rusty) or does MySql not allow UDFs to use additional shared objects?

  • What is the best way to marshal a char array function argument?

    - by Seh Hui 'Felix' Leong
    Let say that given the following signature in LegacyLib.dll: int Login(SysInst *inst, char username[8], char password[6]); The simple way to marshal this function in C# would be: [DllImport("LegacyLib.dll", CharSet=CharSet.Ansi)] public static extern int Login(ref SysInst inst, string username, string password); The problem of doing it in a such a naive way is that the managed string we passed into the username or password parameter could be longer than the array bounds and this could potentially cause a buffer overrun in LegacyLib.dll. Is there a better way which overcomes this problem? i.e. is there any quick [MarshalAs(…)] magic that I could use to counter that?

  • Need to get back form controls' information externally

    - by Tom
    Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

  • runtime loading of ValidateAntiForgeryToken Salt value

    - by p.campbell
    Consider an ASP.NET MVC application using the Salt parameter in the [ValidateAntiForgeryToken] directive. The scenario is such that the app will be used by many customers. It's not terribly desirable to have the Salt known at compile time. The current strategy is to locate the Salt value in the web.config. [ValidateAntiForgeryToken(Salt = Config.AppSalt)] //Config.AppSalt is a static property that reads the web.config. This leads to a compile-time exception suggesting that the Salt must be a const at compile time. An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type How can I modify the application to allow for a runtime loading of the Salt so that the app doesn't have to be re-salted and recompiled for each customer? Consider that the Salt won't change frequently, if at all, thereby removing the possibility of invalidating form

  • Source control on internet i.e. no private networks.

    - by Kavitesh Singh
    Me and my friend are in the process of starting a small project and want to implement a source control. Now both are located in different cities and can communicate using internet for file sharing etc. I need an online hosting solution or any way where i can maintain the source code repository for both of us to check in/out. As of now we want to maintain it as private project. Does sourceforge allow hosting projects which would not be opensource? One option i was thinking, to obtain a static IP form ISP and host the repository.But that mean my system needs to be online when my friend wants to checkin/out or do some diff with old version code. Secondly, would SVN or git be a better choice in such a situation. I have no experience in git/mercurial as of now.

  • OutOfMemoryError calling XmlSerializer.Deserialize() - not related to XML size!

    - by Mike Atlas
    This is a really crazy bug. The following is throwing an OutOfMemoryException, for XML snippits that are very short (e.g., <ABC def='123'/>) of one type, but not for others of the same size but a different type: (e.g., <ZYX qpr='baz'/>). public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Exception ex) { throw; // just for catching a breakpoint. } } I read in this MSDN article that if I were using XmlSerializer with additional parameters in the constructor, I'd end up generating un-cached serializer assemblies every it got called, causing an Assembly Leak. But I'm not using additional parameters in the constructor. It also happens on the first call, too, so the AppDomain is fresh. Worse yet, it is only thrown in release builds, not debug builds. What gives?

  • PerformanceCounterCategory.Exists is very slow if category doesn't exists

    - by Shrike
    I have kind of library which uses a bunch of its own perf counters. But I want my library works fine even if that perf counters weren't installed. So I've created wrappers aroung PerformanceCounter and on the first use check if PerfCounter exists or not. If they exists then I'm using native PerformanceCounter instead I'm using a wrapper which do nothing. So to check perf counter existence I use PerformanceCounterCategory.Exists The problem is that if there isn't such category then PerformanceCounterCategory.Exists call takes (on my machine) about 10 seconds! Needless to say it's too slow. What can I do? Code to try it by youself: using System; using System.Diagnostics; class Program { static void Main(string[] args) { var ts = Stopwatch.StartNew(); var res = PerformanceCounterCategory.Exists("XYZ"); Console.WriteLine(ts.ElapsedMilliseconds); Console.WriteLine("result:" + res); } }

  • Emacs enum indentation

    - by Masterofpsi
    I'm having a problem with Emacs's indentation of Java enums. While it indents the first member OK, it wants to give all of the rest of the static enum members an additional level of indentation. It looks like this: class MyClass { public enum MyEnum { ONE(1), //good TWO(2), // not good! THREE(3), FOUR(4); private final int value; } } When I run C-c C-s on the line that opens the enum, it gives me ((inclass 1) (topmost-intro 1)), which doesn't seem quite right -- it seems like it should be giving brace-list-open. When I run it on the first enum member, it gives me ((defun-block-intro 21)), which is definitely not right. Every subsequent member gives (statement-cont 50). I'm in java-mode and I'm using the java style of indentation. Does anyone know what the problem might be?

  • Synchronising scripts / db / files from dev system to web server

    - by Spoonface
    I work as a freelance web dev, and up until now have been ftping my scripts / databases / static files to my web server manually, but I'm finding that is too error prone. So I'm looking for an app to automate uploading new and updated scripts / files / databases / etc. I know a lot of independent devs use WinSCP or Unison, but I don't think those apps can synch databases. Does anyone have any other suggestions? It doesn't need to be anything overly feature rich as I'm not working within a team or across multiple operating systems or anything like that. I can purchase any reasonably priced license if necesary. My work is primarily for PHP / MySQL / Apache on a Windows system, and then uploaded to a Linux / Apache server. thanks for your time!

  • How I Work: Staying Productive Whilst Traveling

    - by BuckWoody
    I travel a lot. Not like some folks that are gone every week, mind you, although in the last month I’ve been to: Cambridge, UK; Anchorage, AK; San Jose, CA; Copenhagen, DK, Boston, MA; and I’m currently en-route to Anaheim, CA.  While this many places in a month is a bit unusual for me, I would say I travel frequently. I’ve travelled most of my 28+ years in IT, and at one time was a consultant traveling weekly.   With that much time away from my primary work location, I have to find ways to stay productive. Some might say “just rest – take a nap!” – but I’m not able to do that. For one thing, I’m a very light sleeper and I’ve never slept on a plane - even a 30+ hour trip to New Zealand in Business Class - so that just isn’t option. I also am not always in the plane, of course. There’s the hotel, the taxi/bus/train, the airport and then all that over again when I arrive. Since my regular jobs have many demands, I have to get work done.   Note: No, I’m not always focused on work. I need downtime just like everyone else. Sometimes I just think, watch a movie or listen to tunes – and I give myself permission to do that anytime – sometimes the whole trip. I have too fewheartbeats left in life to only focus on work – it’s just not that important, and neither am I. Some of these tasks are letters to friends and family, or other personal things. What I’m talking about here is a plan, not some task list I have to follow. When I get to the location I’m traveling to, I always build in as much time as I can to ensure I enjoy those sights and the people I’m with. I would find traveling to be a waste if not for that.   The Unrealistic Expectation As I would evaluate the trip I was taking – say a 6-8 hour flight – I would expect to get 10-12 hours of work done. After all, there’s the time at the airport, the taxi and so on, and then of course the time in the air with all of the room, power, internet and everything else I needed to get my work done. I would pile up tasks at home, pack my bags, and head happily to the magical land of the TSA.   Right. On return from the trip, I had accomplished little, had more e-mails and other work that had piled up, and I was tired, hungry, and unorganized. This had to change. So, I decided to do three things: Segment my work Set realistic expectations Plan accordingly  Segmenting By Available Resources The first task was to decide what kind of work I could do in each location – if any. I found that I was dependent on a few things to get work done, such as power, the Internet, and a place to sit down. Before I fly, I take some time at home to get all of the work I’d like to accomplish while away segmented into these areas, and print that out on paper, which goes in my suit-coat pocket along with a mechanical pencil. I print my tickets, and I’m all set for the adventure ahead. Then I simply do each kind of work whenever I’m in that situation. No power There are certain times when I don’t have power available. But not only that, I might not even be able to use most of my electronics. So I now schedule as many phone calls as I can for the taxi/bus/train ride and the airports as I can. I have a paper notebook (Moleskine, of course) and a pencil and I print out any notes or numbers I need prior to the trip. Once I’m airborne or at the airport, I work on my laptop. I check and respond to e-mails, create slides, write code, do architecture, whatever I can.  If I can’t use any electronics, or once the power runs out, I schedule time for reading. I can read at the airport or anywhere, actually, even in-flight or any other transport. I “read with a pencil”, meaning I take a lot of notes, which I liketo put in OneNote, but since in most cases I don’t have power, I use the Moleskine to do that. Speaking of which, sometimes as I’m thinking I come up with new topics, ideas, blog posts, or things to teach in my classes. Once again I take out the notebook and write it down. All of these notes get a check-mark when I get back to the office and transfer the writing to OneNote. I’ve tried those “smart pens” and so on to automate this, but it just never works out. Pencil and paper are just fine. As I mentioned, sometime I just need to think. I’ll do nothing, and let my mind wander, thinking of nothing in particular, or some math problem or science question I’m interested in. My only issue with this is that I communicate tothink, and I don’t want to drive people crazy by being that guy that won’t shut up, so I think in a different way. Power, but no Internet or Phone If I have power but no Internet or phone, I focus on the laptop and the tablet as before, and I also recharge my other gadgets. Power, Internet, Phone and a Place to Work At first I thought that when I arrived at the hotel or event I could get the same amount of work done that I do at the office. Not so. There’s simply too many distractions, things you need, or other issues that allow this. Of course, Ican work on any device, read, think, write or whatever, but I am simply not as productive as I am in my home office. So I plan for about 25-50% as much work getting done in this environment as I think I could really do. I’ve done some measurements, and this holds out to be true almost every time. The key is that I re-set my expectations (and my co-worker’s expectations as well) that this is the case. I use the Out-Of-Office notices to let people know that I’m just not going to be 100% at this time – it’s hard for everyone, but it’s more honest and realistic, and I’d rather they know that – and that I realize that – than to let them think I’m totally available. Because I’m not – I’m traveling. I don’t tend to put too much detail, because after all I don’t necessarily want to let people know when I’m not home :) but I do think it’s important to let people that depend on my know that I’ll get back with them later. I hope this helps you think through your own methodology of staying productive when you travel. Or perhaps you just go offline, and don’t worry about any of this – good for you! That’s completely valid as well.   (Oh, and yes, I wrote this at 35K feet, on Alaska Airlines on a trip. :)  Practice what you preach, Buck.)

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • How can I capture multiple matches from the same Perl regex?

    - by Sho Minamimoto
    I'm trying to parse a single string and get multiple chunks of data out from the same string with the same regex conditions. I'm parsing a single HTML doc that is static (For an undisclosed reason, I can't use an HTML parser to do the job.) I have an expression that looks like: $string =~ /\<img\ssrc\="(.*)"/; and I want to get the value of $1. However, in the one string, there are many img tags like this, so I need something like an array returned (@1?) is this possible?

    I have started to develop a web app on google's app engine and i wish to make the static content on the site searchable on google. For example, my app is at http://ajakimov.appspot.com/ and on it there is only some random text like 'form bell road smear sky orange fan glass key'. When i google for 'form bell road smear' for example or the title of the site for that matter , i get no results - cant find the site. Does anyone know how to make a appengine site google-able? Thanks.

  • Java Math.cos() Method Does Not Return 0 When Expected

    - by dimo414
    Using Java on a Windows 7 PC (not sure if that matters) and calling Math.cos() on values that should return 0 (like pi/2) instead returns small values, but small values that, unless I'm misunderstanding, are much greater than 1 ulp off from zero. Math.cos(Math.PI/2) = 6.123233995736766E-17 Math.ulp(Math.cos(Math.PI/2)) = 1.232595164407831E-32 Is this in fact within 1 ulp and I'm simply confused? And would this be an acceptable wrapper method to resolve this minor inaccuracy? public static double cos(double a){ double temp = Math.abs(a % Math.PI); if(temp == Math.PI/2) return 0; return Math.cos(a); }

  • Make object available within php functions without passing them or making them global

    - by Matt
    Hey all, This requirement is just for simplicity for developers and beautiful code. I'm building a template system and I really would just like an object variable to simply be there in all functions. Here's some code: Librarian.php: $class = "slideshow"; $function = "basic"; $args = array(...); $librarian = $this; // I WOULD LIKE THIS TO BE PRESENT IN CALLED FUNCTION ... return call_user_func($class.'::'.$function, $args); ... Slideshow.php: public static function basic($args) { echo $librarian; // "Librarian Object" } Thanks! Matt Mueller

  • How to Create a Generic Method and Create Instance of The Type

    - by DaveDev
    Hi Guys I want to create a helper method that I can imagine has a signature similar to this: public static MyHtmlTag GenerateTag<T>(this HtmlHelper htmlHelper, object obj) { // how do I create an instance of MyAnchor? // this returns MyAnchor, which has a MyHtmlTag base } When I invoke the method, I want to specify a type of MyHtmlTag, such as MyAnchor, e.g.: <%= Html.GenerateTag<MyAnchor>(obj) %> or <%= Html.GenerateTag<MySpan>(obj) %> Can someone show me how to create this method? Also, what's involved in creating an instance of the type I specified? Activator.CreateInstance()? Thanks Dave

  • Grails searchable plugin

    - by Don
    Hi, In my Grails app, I'm using the Searchable plugin for searching/indexing. I want to write a Compass/Lucene query that involves multiple domain classes. Within that query when I want to refer to the id of a class, I can't simply use 'id' because all classes have an 'id' property. Currently, I work around this problem by adding the following property to a class Foo public Long getFooId() { return id } static transients = ['fooId'] Then when I want to refer to the id of Foo within a query I use 'fooId'. Is there a way I can provide an alias for a property in the searchable mapping rather than adding a property to the class?
