  • removing dependancy of a private function inside a public function using Rhino Mocks

    - by L G
    Hi All, I am new to mocking, and have started with Rhino Mocks. My scenario is like this..in my class library i have a public function and inside it i have a private function call, which gets output from a service.I want to remove the private function dependency. public class Employee { public virtual string GetFullName(string firstName, string lastName) { string middleName = GetMiddleName(); return string.Format("{0} {2} {1}", firstName, lastName,middleName ); } private virtual string GetMiddleName() { // Some call to Service return "George"; } } This is not my real scenario though, i just wanted to know how to remove dependency of GetMiddleName() function and i need to return some default value while unit testing. Note : I won't be able to change the private function here..or include Interface..Keeping the functions as such, is there any way to mock this.Thank

  • How to correctly hook and return GetDlgItemTextA from C++ to C# to C++ from EasyHook

    - by Gbps
    I'm using EasyHook, a C# library for injecting and detouring functions from unmanaged applications. I'm trying to hook onto GetDlgItemTextA, which takes the arguments: UINT WINAPI GetDlgItemText( __in HWND hDlg, __in int nIDDlgItem, __out LPTSTR lpString, __in int nMaxCount );` In my hook, I am casting it as: [DllImport("user32.dll", // CharSet = CharSet.Unicode, SetLastError = true, CallingConvention = CallingConvention.StdCall)] static extern uint GetDlgItemTextA(IntPtr hWin, int nIDDlgItem, StringBuilder text, int MaxCount); And my hook is: static uint DGetDlgItemText_Hooked(IntPtr hWin, int nIDDlgItem, StringBuilder text, int MaxCount) { // call original API... uint ret = GetDlgItemTextA(hWin, nIDDlgItem, text, MaxCount); MessageBox.Show(text.ToString()); return ret; } Unfortunately, the moment this is called, the hooked application crashes. Is there a better cast I can use to successfully hook onto this function? Thanks! I've compiled, editted, and confirmed the working condition of my EasyHook setup. This is just casing and hooking only.

  • Ways to optimize Android App code based on function call stack?

    - by K-RAN
    I've been told that Android OS stores all function calls in a stack. This can lead to many problems and cause the 'hiccups' during runtime, even if a program is functionalized properly, correct? So the question is, how can we prevent this from happening? The obvious solution is to functionalize less, along with other sensible acts such as refraining from excessively/needlessly creating objects, performing static calls to functions that don't access fields, etc... Is there another way though? Or can this only be done through careful code writing on the programmers' part? Does the JVM/JIT automatically optimize the bytecode during compile time to account for this?? Thanks a lot for your responses!!

  • How to maintain fixed size of C variable types over different machines?

    - by Alex
    I've all this kind of functions. ssize_t fuc1(int var1, void *buf, size_t count); int func2(char *charPtr, int mode, int dev); short func3( long var2); problem is that data types in C has different sizes when compiled on different machines(64bit & 32bit). This is true for even void*. For some reasons. I need to ensure that these sizes all are same on every machine(64bit & 32bit). So, how should I modify these ?

  • Unsigneds in order to prevent negative numbers

    - by Bruno Brant
    let's rope I can make this non-sujective Here's the thing: Sometimes, on fixed-typed languages, I restrict input on methods and functions to positive numbers by using the unsigned types, like unsigned int or unsigned double, etc. Most libraries, however, doesn't seem to think that way. Take C# string.Length. It's a integer, even though it can never be negative. Same goes for C/C++: sqrt input is an int or a double. I know there are reasons for this ... for example your argument might be read from a file and (no idea why) you may prefer to send the value directly to the function and check for errors latter (or use a try-catch block). So, I'm assuming that libraries are way better designed than my own code. So what are the reasons against using unsigned numbers to represent positive numbers? It's because of overflow when we cast then back to signed types?

  • Adapting methods which return true/false

    - by James P.
    What's the best practise when adapting C-style functions which return a true/false to Java? Here's a simple method to illustrate where the problem lies. public static boolean fileNameEndsWithExtension( String filename, String fileExtension) { return filename.endsWith( fileExtension ); } Note that there's probably a more elegant way of filtering files (feel free to comment on this). Anyway, if filename is a null value, does one: Return a false if filename is null? If so, how does one go about distinguishing between the case where filename is null and the case where the String or file name doesn't end with a given file extension? Change the return type to the wrapper class Boolean which allows a null value. Throw an Exception and force the programmer to make sure that a null value is never passed to the method? Use another solution?

  • Server-side access to Client Browser's Latitude/Longitude using Django.

    - by ZenGyro
    Hello, So i am writing a little app that compares a user's position against a database on web-based server written using Django and performs some functions with it. Accessing the browser's geolocation data (in supported browsers ) is fairly trivial using JavaScript. But what is the best way to allow the Django server to access the longitude and latitude variables? Is it best to wrap them up as a JSON object and send to the server via POST? Or is there some easier (Geo)Django-based way to access the Navigator.geolocation browser object. Please forgive a newbie a question like this, but my Google-Fuing only seems to find ways to insert variables into JavaScript via template tag, whereas I need it to work the other way! Any advice or code snippets greatly appreciated. Feel free to talk to me like I am an idiot.

  • IPhone: different system timers??

    - by matt
    I have been using mach_absolute_time() for all my timing functions so far. calculating how long between frames ect. I now want to get the exact time touch input events happen using event.timestamp in the touch callbacks. the problem is these two seem to use completely different timers. sure, you can get them both in seconds, but their origins are different and seemingly random... is there any way to sync the two different timers? or is there anyway to get access to the same timer that the touch input uses to generate that timestamp property? otherwise its next to useless.

  • Are there any context-sensitive code search tools?

    - by Vicky
    I have been getting very frustrated recently in dealing with a massive bulk of legacy code which I am trying to get familiar with. Say I try to search for a particular function call, I get loads of results that turn out to be completely irrelevant; some of them are easy to spot, eg a comment saying // Fixed functionality in foo() so don't need to handle this here any more But others are much harder to spot manually, because they turn out to be calls from other functions in modules that are only compiled in certain cases, or are part of a much larger block of code that is #if 0'd out in its entirety. What I'd like would be a search tool that would allow me to search for a term and give me the choice to include or exclude commented out or #if 0'd out code. Then the search results would be displayed alongside a list of #defines that are required in order for that snippet of code to be relevant. I'm working in C / C++, but other than the specific comment syntax I guess the techniques should be more generally applicable. Does such a tool exist?

  • jQuery plugin call internal function

    - by pbcoder
    I want to call removeSomething() (see in line 9) internally: JS-Code is: (function($){ $.fn.extend({ Engine: function(options) { var defaults = { ... }; var options = $.extend(defaults, options); removeSomething(); //----------------------------------------------------------------------- //Public Functions ------------------------------------------------------ //----------------------------------------------------------------------- this.removeSomething = function() { ... }; } }); })(jQuery); But if I call removeSomething console outputs that removeSomething is not a function, how do I have to call this function? The function should be available internally and externally. Thanks for help!

  • Parsing plain data with Javascript (JQuery)

    - by Angelus
    Well , I have this text in a Javascript Var: GIMP Palette Name: Named Colors Columns: 16 # 255 250 250 snow (255 250 250) 248 248 255 ghost white (248 248 255) 245 245 245 white smoke (245 245 245) 220 220 220 gainsboro (220 220 220) 255 250 240 floral white (255 250 240) 253 245 230 old lace (253 245 230) 250 240 230 linen (250 240 230) 250 235 215 antique white (250 235 215) 255 239 213 papaya whip (255 239 213) And What I need is to cut it in lines and put them in one Array , after that i must separate each number and the rest in an string. I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

  • how to keep the value of a variable in a closure

    - by Florian Fida
    i need to create multiple javascript functions which have a static id inside, so the function itself knows what data to process. Here is some code: (function(){ function log(s){ if(console && console.log) console.log(s); else alert(s); } var i = 10; while (i--){ window.setTimeout(function(){ // i need i to be 10, 9, 8... here not -1 log(i); },500); } })(); The problem ist that i allways gets updated by the loop, and i need to prevent this. Thanks in advance for any help, comments or tips!

  • How to make schema and code dynamic?

    - by Jonarch
    I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

  • MacOSX: OSAtomic vs OSAtomicBarrier

    - by anon
    For the functions here: #include <libkern/OSAtomic.h> there are OSAtomic and OSAtomicBarrier versions. However, the documentation does not show sample code for: When is it safe to use just OSAtomic, without the OSAtomicBarrier version When is it that OSAtomic would be unsafe, but OSAtomiBarrier would be safe. Can anyone provide explainations + sample codes? [Random ramblings of "your opinion" without actual code is useless. Readers: please down vote such answers; and vigrously upvote answers with actual code.] [C/C++ code preferred; Assembly okay too.]

  • How can I (from a script) add something to the zsh command history?

    - by Brandon
    I'd like to be able to look through my command history and know the context from which I issued various commands--in other words, "what directory was I in?" There are various ways I could achieve this, but all of them (that I can think of) would require manipulating the zsh history to add (for instance) a commented line with the result of $(pwd). (I could create functions named cd & pushd & popd etc, or I could use zsh's preexec() function and maybe its periodic() function to add the comment line at most every X seconds, just before I issue a command, or perhaps there's some other way.) The problem is, I don't want to directly manipulate the history file and bypass the shell's history mechanism, but I can't figure out a way (with the fc command, for instance) to add something to the history without actually typing it on the command line. How could I do this?

  • Article about code density as a measure of programming language power

    - by prosseek
    I remember reading an article saying something like "The number of bugs introduced doesn't vary much with different programming languages, but it depends pretty much on SLOC (source lines of code). So, using the programming language that can implement the same functions with smaller SLOC is preferable in terms of stability." The author wanted to stress the advantages of using Functional Programming, as normally one can program with a smaller number of LOC. I remember the author cited a research paper about the irrelevance of choice of programming language and the number of bugs. Is there anyone who knows the research paper or the article?

  • jQuery doesn't fire some events while I'm not logged in (Joomla)

    - by Andrew Sekaev
    So basically, .resize function fails until I log in. What does that mean? And how that can be fixed? Almost all other functions work fine. The site is still in developement, so no live version sadly. UPDATE: jQuery(window).resize(function() { var windowSize = jQuery(window).width() var windowWidth = (jQuery(window).width()-60)/6; var windowHeight = windowWidth/1.6; /*grid resize*/ jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight}); }); This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...

  • checksum error with building an HTTP packet(but over TCP, like syn/ack its ok)

    - by Hila
    I am building a NAT program,I change each packet that comes from our internal subnet, change it's source IP address by libnet functions.( catch the packet with libpcap, put it sniff structures and build the new packet with libnet) I am trying to build an http packet. When I look on wireshark, I see that the new packet that I have built is exectly like the original packet(the only diffrent is that I changed the src port and ip), but there is a checksum error, So the server don't do anything with the packet that I have sent to him, beacuse the cheksum field is wrong. When I send a tcp packet(like syn or ack), the checksum is ok, and the server respons. Is anyone knows what can cause this problem? the new checksum in other packets is calculated as it should be.. but in the HTTP packet it doesn't..

  • How can i convert between F# List and F# Tuple?

    - by ksharp
    Is there some way to convert between F# List and F# Tuple? For example: [1;2;3] -> (1,2,3) (1,2,3,4) -> [1;2;3;4] I need two Functions to do that: let listToTuple list = ... let tupleToList tuple = ... Thank you in advance. I think reflection is necessary to this problem. I know the performance is not good. I have to pay the cost of breaking functional programming rule.

  • jquery toggle+paginate+multiple instances

    - by mark
    Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

  • C++ setTimout function ?

    - by Quandary
    What's the cheapest way for a JavaScript like setTimeout-function in C++? I would need this: 5000 miliseconds from now, start function xy (no parameters, no return value). The reason for this is I need to initialize COM for text to speech, but when I do it on dll attach, it crashes. It works fine however if I do not call CoInitialize from dllmain. I just need to call CoInitialize and CoCreateInstance, and then use the instance in other functions. I can catch the uninitialized instance by checking for NULL, but I need to initialize COM - without crashing.

  • How to get array keys in Javascript?

    - by DisgruntledGoat
    I have an array created with this code: var widthRange = new Array(); widthRange[46] = { sel:46, min:0, max:52 }; widthRange[66] = { sel:66, min:52, max:70 }; widthRange[90] = { sel:90, min:70, max:94 }; I want to get each of the values 46, 66, 90 in a loop. I tried for (var key in widthRange) but this gives me a whole bunch of extra properties (I assume they are functions on the object). I can't use a regular for loop since the values are not sequential.

  • An easy way to replace fread()'s with reading from a byte array?

    - by Sam Washburn
    I have a piece of code that needs to be run from a restricted environment that doesn't allow stdio (Flash's Alchemy compiler). The code uses standard fopen/fread functions and I need to convert it to read from a char* array. Any ideas on how to best approach this? Does a wrapper exist or some library that would help? Thanks! EDIT: I should also mention that it's reading in structs. Like this: fread(&myStruct, 1, sizeof(myStruct), f);

  • JavaScript using toString on a Function object to read text content

    - by mseeley
    Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

  • Wordpress page linking

    - by danixd
    I am trying to implement WordPress into quite a large site with a complex page structure and struggling to get normal pages to work (not created through the admin) The pages are created, but when I link to them, nothing happens... The desired url - www.website.com/dir1/dir2/dir3/page.php The actual url- www.website.com/wp-content/themes/themename/dir1/dir2/dir3/page.php The problem with linking to the latter is that it breaks the WordPress functions I don't want to have to give every page a template, then add it through the admin, it is too much work. I only need 2 pages to contain dynamic content. Am I being silly? I am really confused.
