• Getting installed app size

  - by alex

  I'm trying to figure out how to get the size of an installed app. What's already failed: - new File('/data/app/some.apk') - reports incorrect size - PackageManager.getPackageSizeInfo(String packageName, IPackageStatsObserver observer) - is @hide and relies on some obscure IPackageStatsObserver for result so I can't call it via reflection.

• When mocking a class with Moq, how can I CallBase for just specific methods?

  - by Daryn

  I really appreciate Moq's Loose mocking behaviour that returns default values when no expectations are set. It's convenient and saves me code, and it also acts as a safety measure: dependencies won't get unintentionally called during the unit test (as long as they are virtual). However, I'm confused about how to keep these benefits when the method under test happens to be virtual. In this case I do want to call the real code for that one method, while still having the rest of the class loosely mocked. All I have found in my searching is that I could set mock.CallBase = true to ensure that the method gets called. However, that affects the whole class. I don't want to do that because it puts me in a dilemma about all the other properties and methods in the class that hide call dependencies: if CallBase is true then I have to either Setup stubs for all of the properties and methods that hide dependencies -- Even though my test doesn't think it needs to care about those dependencies, or Hope that I don't forget to Setup any stubs (and that no new dependencies get added to the code in the future) -- Risk unit tests hitting a real dependency. Q: With Moq, is there any way to test a virtual method, when I mocked the class to stub just a few dependencies? I.e. Without resorting to CallBase=true and having to stub all of the dependencies? Example code to illustrate (uses MSTest, InternalsVisibleTo DynamicProxyGenAssembly2) In the following example, TestNonVirtualMethod passes, but TestVirtualMethod fails - returns null. public class Foo { public string NonVirtualMethod() { return GetDependencyA(); } public virtual string VirtualMethod() { return GetDependencyA();} internal virtual string GetDependencyA() { return "! Hit REAL Dependency A !"; } // [... Possibly many other dependencies ...] internal virtual string GetDependencyN() { return "! Hit REAL Dependency N !"; } } [TestClass] public class UnitTest1 { [TestMethod] public void TestNonVirtualMethod() { var mockFoo = new Mock<Foo>(); mockFoo.Setup(m => m.GetDependencyA()).Returns(expectedResultString); string result = mockFoo.Object.NonVirtualMethod(); Assert.AreEqual(expectedResultString, result); } [TestMethod] public void TestVirtualMethod() // Fails { var mockFoo = new Mock<Foo>(); mockFoo.Setup(m => m.GetDependencyA()).Returns(expectedResultString); // (I don't want to setup GetDependencyB ... GetDependencyN here) string result = mockFoo.Object.VirtualMethod(); Assert.AreEqual(expectedResultString, result); } string expectedResultString = "Hit mock dependency A - OK"; }

• Using jQuery to perform a GET request and using the resulting data

  - by Filip Ekberg

  I have a page, let's call it "callme.html" which only has this content: abc Now I want to fire the following: $.get("callme.html", function (data) { alert(data); }, "text"); I am using jQuery 1.4.2 mini and the page is called but the alert is empty. Any ideas why? I'd like the popup to contain abc I've also tried the following $.ajax({ url: "callme.html", async: false, success: function (data) { alert(data); } });

• C++ error message output format

  - by sub

  If I want to trigger an error in my interpreter I call this function: Error( ErrorType type, ErrorSeverity severity, const char* msg, int line ); However, with that I can only output Name error: Undefined variable in line 1 instead of Name error: Undefined variable 'someVariableName' in line 1 I'm working entirely with strings (except for the error messages as they all are constant at the moment), so sprintf won't work. What is the best way to create an efficient error function that can output a constant message combined with a string that describes which object, e.g.: a non-existing variable, triggered the error?

• Accessing PCI Device from user space programs

  - by crissangel

  I have a device which would be interface with my processor through pcie. I have written driver for it using the existing pci file operations. Now my problem is how do I access it from user space programs? PCI File operations do not have IOCTL support and hence I cant make an ioctl call unlike other char devices. I cannot use pci_config_read_byte etc. functions as they are meant for kernel space(included in linux/pci.h).

• How can I control standard out of C++ routines wrapped with SWIG and exposed in Python?

  - by cmdev

  Is it possible to control the standard streams of C++ code in python? So the code is wrapped with SWIG and then exposed to python where I call its functions. I am getting all kinds of unwanted messages coming from C++ code and I want to suppress them either by not using the stream or by redirecting it to a bit bucket.

• ODBC: when is the best time to create my database?

  - by mawg

  I have a windows program which generates PGP forms which will be filled in later. Those PHP forms will populate a database. It looks very much like MySql, but I can't be certain, so let's call it ODBC. And, yes, it does have to be a windows program. There will also be PHP forms which query the database - examine which tables and fields it contains and then generates forms which can be used to search the database (e.g, it finds a table with fields "employee_name", etc and generates a form which lets you search based on employee name. Let's call that design time and run time. At design time, some manager or IT guy or similar gets to define the nature of the database and at runtime 1) a worker fills in the form daily and 2) management can extract reports. Here's my question: given that the database is defined at "design time" (and populated at run time), where and how is best to do so? 1 I could use an ODBC interface from the windows program, but I am having difficulty finding something good to work with Delphi. Things like ADO and firebird tend to expect you to already have a database and allow you to manipulate it, but I can find no code example of how to create a database and some tables, so ... 2 I could used DOS commands from Delphi in my windows program. I just tried and got a response to MySql --version, but am not sure if MySql etc are more interactive. That is, can I use a script file or a very long stacked command with semicolons and returns separating? e.g 'CREATE DATABASE db; CREATE TABLE t1;' 3) Since the best way to work with databases seems to be PHP, perhaps my windows program could spit out a PHP page which would, when run in a browser, create the database. I have tried to make this as uncomplicated as I can, but please feel free to ask questions. It may be that there are several valid ways, but there is probably one 'better' solution in terms of ease of implementation or maintenance. Better scratch option 3. What if the user later wants to come back and have the windows program change the input form? It needs to update the database too.

• How to checking wether an object has a specific method or not

  - by Ghommey

  Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell wether $myObject has a method called helloWorld or not?

• How can I run an external program from C and parse its output?

  - by Josh Matthews

  I've got a utility that outputs a list of files required by a game. How can I run that utility within a C program and grab its output so I can act on it within the same program? UPDATE: Good call on the lack of information. The utility spits out a series of strings, and this is supposed to be complete portable across Mac/Windows/Linux. Please note, I'm looking for a programmatic way to execute the utility and retain its output (which goes to stdout).

• Trigger function on deserialization

  - by Tom Savage

  I have a class with a number of fields which are normally calculated in the constructor from other data in the class. They are not serialized to XML because any changes to the rest of the data will likely require their recalculation. Is there a way I can set up a function call to be triggered on deserialization?

• Safe Cross Thread Signals/Slot C++

  - by JP

  It seem that the only implementation that provide Safe Cross-Thread Signals for both the Signal class and what's being called in the slot is QT. (Maybe I'm wrong?). But I cannot use QT in the project I'm doing. So how could I provide safe Slots call from a different thread (Using Boost::signals2 for example)? Are mutex inside the slot the only way? I think signals2 protect themself but not what's being done inside the slot. Thanks

• jQuery - Save to SQL via PHP

  - by Kenny Bones

  This is probably easy for you guys, but I can't understand it. I want to save the filename of an image to it's own row in the SQL base. Basically, I log on to the site where I have my own userID. And each user has its own column for background images. And the user can choose his own image if he wants to. So basically, when the user clicks on the image he wants, a jquery click event occurs and an ajax call is made to a php file which is supposed to take care of the actual update. The row for each user always exist so there's only an update of the data that's necessary. First, I collect the filename of the css property 'background-image' and split it so I get only the filename. I then store that filename in a variable I call 'filename' which is then passed on to this jQuery snippet: $.ajax({ url: 'save_to_db.php', data: filename, dataType:'Text', type: 'POST', success: function(data) { // Just for testing purposes. alert('Background changed to: ' + data); } }); And this is the php: <?php require("dbconnect.php") ?> <?php $uploadstring = ($_POST['filename']); mysql_query("UPDATE brukere SET brukerBakgrunn = $uploadstring WHERE brukerID=" .$_SESSION['id'] .""; mysql_close(); ?> Basically, each user has their own ID and this is called 'brukerID' The table everything is in is called 'brukere' and the column I'm supposed to update is the one called 'brukerBakgrunn' When I just run the javascript snippet, I get this message box in return where it says: Background changed to: Parse error: syntax error, unexpected ';' in /var/www/clients/client2/web8/web/save_to_db.php on line 8 I actualle get this messagebox twice, not sure why. Line 8 in 'save_to_db.php' is this one: mysql_query("UPDATE brukere SET brukerBakgrunn = $uploadstring WHERE brukerID=" .$_SESSION['id'] .""; Not sure if you need to see db_connect.php as well. I can add that later if you need to see it. So what am I missing here?

• Best practise - Accessing preferences globally

  - by JK

  User preferences for my app is store in NSUserDefaults. This includes a "theme" preference, which needs to be accessed frequently by multiple classes. I would prefer not to call "[[NSUserDefaults standardUserDefaults] objectForKey:..." repeatedly as it makes for inconcise code and I assume will incur overhead. What is the preferred and most concise method for accessing preferences in any class?

• How to tell if a DLL function is being called from a VB6 exe?

  - by aiGuru

  I have an old VB6 app and I'm not sure which code was used to compile it. One revision of the source makes a call to Sleep in kernel32.dll. Is there a way to find out if the exe calls a specific function in a DLL? I can see that kernel32.dll is linked by using the "Dependency Walker" tool but that doesn't seem to tell me that a specific function is called from the exe.

• Bash Color Variable Output

  - by drewrockshard

  I've got a variable, let's say $x and it holds the value of website.com. I want to be able to call the variable and apply shell color to it like so: echo -e '\033[1;32m$x:\033[0m'; The problem is not the color, however, it's how the script it interpretting the output. So the output I'm getting is: $x: I need the output to obviously be the string in the variable, and not the variable name. Is there any way around this issue?

• matplotlib - changing rect colours on the fly

  - by Nick

  I am playing with matplotlib - I have a bar chart, and I want to highlight the bar which user clicks. I have a callback that goes through a rect collection (the one I got from self.axis.bar(...)) and finds out which one was clicked (looking at the coordinates). At this point I want to call something to change the colour of the current bar. Is it possible? How do I do that?

• iPhone images on the simulator and the actual device - different bitsPerPixel values?

  - by Reuven

  Hi there, I have code running in an iPhone application I am developing. Basically, the code needs to load an images and calls: size_t bitsPerPixel = CGImageGetBitsPerPixel(imageRef); I noticed that on the iPhone simulator this call returns 24 and the device itself it returns 32. Is this behavior by design? Is it something I can control? Thanks!
