• Android: Easiest way to make a WebView display a Bitmap?

  - by legr3c

  I have some images that I loaded from a remote source stored in Bitmap variables and I want to display them. In addition to switching between these images the user should also be able to zoom and pan them. My first idea was to somehow pass them via an intent to the built-in gallery application but this doesn't seem to be possible. A solution that is suggested in several places is using a WebView since it already supports zooming and panning. My question is how does my Bitmap data get into the WebView? Do I have to write it to a file first, which I would have to remove again later, or is there an easier way? Or are there even better ways to accomplish my main goal, which is displaying Bitmap data as zoomable and panable images?

• What topic in computer science is this?

  - by jasonbogd

  Hi, I am trying to figure out what 'topic' this is called, so I can learn more about it. Basically, I'm talking about designing my applications's architecture. I'm not talking about algorithms. More like -- this class should have these methods and these instance variables, and communicate with this class in this way, this class should have these responsibilities etc. Can anybody tell me what the name of this topic is called and how I can get better at doing this? Thanks.

• [C#] Is variable assignment and reading atomic operation (threading)

  - by AStrangerGuy

  I was unable to find any reference to this in the documentations... Is assigning to a double (or any other simple type, including boolean) an atomic operation viewed from the perspective of threads? double value = 0; public void First() { while(true) { value = (new Random()).NextDouble(); } } public void Second() { while(true) { Console.WriteLine(value); } } In this code sample, first method is called in one thread, and the second in another. Can the second method get a messed up value if it gets its execution during assignment to the variable in another thread? I don't care if I recieve the old value, it's only important to receive a valid value (not one where 2 out of 8 bytes are set). I know it's a stupid question, but I want to be sure, cause I don't know how CLR actually sets the variables. Thanks

• How can I use the SSRS ReportViewer from VS 2008 in a VS2010 project?

  - by Adrian Grigore

  Hi, I'm working on an ASP.NET MVC 2 / .NET 3.5 project which includes SSRS 2008 reports. After migrating to VS 2010 RC, the new web forms report viewer has been giving so much trouble that I'd like to use the old report viewer from VS 2008 again. Now I'm just wondering what would be the easiest way to do that. The report viewer is embedded in a Webforms ASPX file which is loaded in an IFrame by the the MVC view. Report parameters are currently stored as session variables, and for security reasons I would prefer not to change that for HTTP POST or GET parameters. So I can't just put the report viewer in a separate application and build that with VS2008. Moving the entire project back to VS 2008 is not an option. So, what's the easiest way for me to use the VS 2008 ReportViewer in VS 2010? Is there way to grab an assembly from VS 2008 and use that in my project? Thanks, Adrian

• Cast to Extended Class in C# (dotnet 3.5<)

  - by csharpnoob

  Hi, i'm not sure if it's possible. I have a class car and a class mycar extended from class car. Class mycar has also a string list. Only difference. How can i cast now any car object to a mycar object without assigning all attributes each by hand. Like: Car car = new Car(); MyCar mcar = (MyCar) car; or MyCar mcar = new MyCar(car); or however i can extend car with own variables and don't have to do always Car car = new Car(); MyCar mcar = new MyCar(); mcar.name = car.name; mcar.xyz = car.xyz; ... Thanks.

• Complete if statement with strings and array of strings

  - by RandomBen

  I have a page that has 3 variables. They look like this: String[] Headers = new String[] { "Max Width", "Max Length", "Max Height" }; String currentHeader = (String)HttpContext.Current.Request.QueryString["ItemHas"] ?? ""; String checkString = (String)HttpContext.Current.Request.QueryString["ItemIn"] ?? ""; The checkString is a list of Headers delimited by a "|". What is the easiest way to check if my currentHeader is in my Headers array and in my checkString String? I can do it but not in less than 20 lines of code. That seems like a less than optimal solution.

• Installing Recaptcha in Joomla 1.5 user registration

  - by Samuel

  I am trying to install ReCaptcha into the user registration of Joomla 1.5. This may just be an issue with Joomla but when i hit register nothing happens. I think it's doing some JavaScript form validation but there is nothing telling the user what went wrong. if, God forbid, they do fill out the form correctly Joomla will redirect the user to the homepage and give no notice of success. Is this a Joomla issue or is there something wrong with my install? Does anyone know of a plug-in or module for Joomla that would make this easier? Thanks in advance, Samuel UPDATE: Joomla does a lot of "stuff"/"something" to the $_POST and $_GET variables which was causing the reCaptcha to not function. This was for work which is past so I am not spending anymore time on it. Shameless Plug: use wordpress instead. this can be closed as I don't have time to verify which answer works

• JSF2 ResourceBundleLoader override?

  - by CDSO1

  I need to have resource messages that contain EL expressions be resolved when loaded from a ResourceBundle. Basically I have a number of properties files containing the text. Some of the text will look like the following: welcomeText=Welcome #{userbean.name} The only possible way I can see this working currently is implementing a custom taglib so that instead of saying: <f:loadBundle var="messages" basename="application.messages"/> I would have to use <mytaglib:loadBundle var="messages" basename="application.messages"/> #{messages.welcomeText} Given a user with username "User1", this should output Welcome User1 My implementation would then use a custom ResourceBundle class that would override handleGetObject, use the ELResolver to resolve variables etc....Ideas? suggestings? Implementations that are already available? I appreciate your assistance.

• Tracking Google Analytics events with server side request automation

  - by Esko

  I'm currently in the process of programming an utility which generates GA tracking pixel (utm.gif) URL:s based on given parameters. For those of you who are wondering why I'm doing this on the server side, I need to do this server side since the context which I'm going to start tracking simply doesn't support JavaScript and as such ga.js is completely useless to me. I have managed to get it working otherwise quite nicely but I've hit a snag: I can't track events or custom variables because I have no idea how exactly the utme parameter's value should be structured to form a valid event or var type hit. GA's own documentation on this parameter isn't exactly that great, either. I've tried everything from Googling without finding anything (which I find ironic) to reverse engineering ga.js, unfortunately it's minified and quite unreadable because of that. The "mobile" version of GA didn't help either since officially GA mobile doesn't support events nor vars. To summarize, what is the format of the utme parameter for page hit types event and custom variable?

• What is the characteristic of spaghetti code ?

  - by justjoe

  Somebody said that when your PHP Code and application use global variable then it must be a spaghetti code (i assume this). I use wordpress a lot.

• Convert binary information to regular data type without outside modules in python.

  - by vgm64

  Hello World. I'm tasked with reading a poorly formatted binary file and taking in the variables. Although I need to do it in C++ (ROOT, specifically), I've decided to do it in python because python makes sense to me, but my plan is to get it working in python and then tackle re-writing in in C++, so using easy to use python modules won't get me too far later down the road. Basically, I do this: In [5]: some_value Out[5]: '\x00I' In [6]: ''.join([str(ord(i)) for i in some_value]) Out[6]: '073' In [7]: int(''.join([str(ord(i)) for i in some_value])) Out[7]: 73 And I know there has to be a better way. What do you think?

• jQuery $.ajax success must be a callback function?

  - by b. e. hollenbeck

  I've created a wrapper function for jQuery's $.ajax() method so I can pass different dataTypes and post variables - like so: function doPost(dType, postData, uri){ $.ajax({ url: SITE_URL + uri, dataType: dType, data: postData, success: function(data){ return data; }); } The problem I'm having is getting the data (which is always JSON) back out. I've tried setting a var ret before the $.ajax() function call and setting it as ret = data in the success function. Am I being stupid about this? If I don't set a success function, will the $.ajax simply return the data? Or is it just success: return data? Or does success require a callback function to handle the data, which could just be return data?

• aspnet membeship logon page and https redirect

  - by DefSol

  Hello, I have a gridview control that has on onclick event bound to every cell. Once a user clicks on a cell it directs them to a booking confirmation page and passes 3 url variables. This booking page is behind a aspnet membership and thus if the user is not logged in they are served the login page. The login page has a redirect to https connection in the onload event using the IsSecure property. The issue is once the user logs in, then is returned to the booking confirmation page I lose 2 of the url vars. If I remove the https redirect, everything works fine, but the user logs on on a http connection, which is not cool. Appreciate and help thanks Reuben

• curl object moved here error, bash

  - by adam n

  I'm trying to download an html file with curl in bash. When I download it manually, it works fine. However, when i try and run my script through crontab, the output html file is very small and just says "Object moved to here." with a broken link. Does this have something to do with the sparse environment the crontab commands run it? I found this question: http://stackoverflow.com/questions/1279340/php-ssl-curl-object-moved-error but i'm using bash, not php. What are the equivalent command line options or variables to set to fix this problem in bash? (I want to do this with curl, not wget)

• Escaping Hyphens with pkg-config through qmake

  - by Nexus

  I am trying to compile an application using qmake that is using pkg-config to bring in yaml-cpp. Unlike using pkg-config through the terminal qmake which is formatted like: pkg-config --libs --cflags yaml-cpp qmake actually spits out the include paths inside the make command like this: -I/usr/local/include/yaml-cpp This include path breaks subsequent includes which I've set in my qmake file. It's not possible for me to rearrange these includes due the order in which qmake parses its variables. Is it possible using qmake to escape the quote somehow or to make it use the first quoted configuration?

• Dealing with the lack of closures in Objective-C

  - by Sean Clark Hess

  Maybe it's just the fact that I've been using http://nodejs.org/ lately, but the lack of closures in Objective-C (iphone) has been really hard to work around. For example, I'm creating service classes. Each service class can have several methods, each of which makes a different URL request. I can use the delegate pattern, but that means that I have to create a new service each time I want to call a method on it (because it has to store the delegate and selector for that request, and new method calls would overwrite them). Even more difficult for me is the fact that I can't easily keep local variables around in the scope for a callback. I have to store anything I want to send back to the delegate on the service class itself, which makes it harder to have more than one method on each class. How do you pros do it? Should I just quit whining and do it another way?

• FitNesse doesn't call setters in my fixture

  - by Maurits Rijk

  I have copied a trivial example from the FitNesse Two-Minute example: package com.mrijk; import fit.ColumnFixture; public class Foobar extends ColumnFixture { private double numerator; private double denominator; public void setNumerator(double numerator) {this.numerator = numerator;} public void setDenominator(double denominator) {this.denominator = denominator;} public double quotient() {return numerator/denominator;} } However all test fail with: "Could not find field: denominator.", so obviously the setDenominator is not found/used. When I make the the variables numerator and denominator public instead of private, the tests run successfully. I must be overlooking something, but can't see it yet. Anyone?

• Memory leak found with clang but cant release and autorelease crashes

  - by Rudiger

  I have a class that builds a request based on a few passed in variables. The class also has all the delegate methods to receive the data and stores it in a property for the calling class to retrieve. When the class initializes it creates a connection and then returns itself: NSURLConnection *connection; if (self = [super init]) { self.delegate = theDelegate; ...some code here... connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES]; } return self; So I can't release it normally and if I autorelease it crashes. Is it the job of the calling class to release? And if so does just releasing the initilised object also release connection or do you have to release it specifically? If so how would you? Thanks

• PHP: Set max_file_uploads for one file rather than php.ini

  - by Jenkz

  Like many variables in PHP using ini_set() on a page doesn't actually work. I've recently upgraded my PHP version and found that my multiple image uploader is now capped. After 3 hours of frustration, I've found that my new PHP install has the new "max_file_uploads" parameter set to "20". So only the first 7 images get uploaded (each is in three sizes, 7*3=21). I can now change my php.ini value of "max_file_uploads" to 300, but I'd rather not do that side wide. Is there any way to set that value just for a single file (upload.php)? Could a .htaccess file be used for this?

• How do you load the app.config file into a DLL

  - by Bluephlame

  So I cant find a definitive answer to the Question. How do you load the app.config file into a DLL. I understand that generally the App.config info should be put into the executable app.config. However i am building an add-in and have to executable available. I would like to use the namespace.dll.config file to store my variables, but i need a way of loading it into the system. Do you need to build out some code to load this file in? Can you use the configurationManager namespace to make this happen easily?

• iPhone NSXMLParser parsing string and storing in a NSNumber variable and different data types

  - by anubhav

  Hi, I am trying to parse a XML File using NSXMLParser, I also have a Container class, in which I have a few instance variables. One of the elements that I am trying to parse in the XML is: <book sn="32.859669048339128" pn="-116.917800670489670"> I am trying to save the value of sn and pn in an instance variable of object Container: NSNumber *sn, NSNumber *pn. I want it so that when my parser get the attributeValues it can save it as a Double (or float) in those NSNumber pointers. Right now, all it does it just saves a string to the NSNumber. The Parser Code looks like this: if([elementName isEqualToString:@"book"]){ container = [[Container alloc] init]; container.sn=[attributeDict objectForKey:@"sn"]; container.pn=[attributeDict objectForKey:@"pn"]; } I want it so that the type of container.sn is initialized to a float or double. Any ideas how to do this? Thanks in advance!

• Easier debugging stl array

  - by bobobobo

  In MSVC++ I have a vector. Whenever you go out of bounds of the vector (in debug mode, launched as "Start Debugging"), when you step out of bounds of the vector the program halts with a dialog box: Microsoft Visual C++ Debug Library ==== Debug Assertion Failed! Expression: Vector subscript out of range Abort | Retry | Ignore So what I want though is the MSVC++ debugger within visual studio to STOP AT THE LINE WHERE THE OUT OF BOUNDS OCCURRED, not give me this dialog box. How can I cause the program to "break" properly and be able to step through code /inspect variables when an out of bounds occurs on an STL vector?
