  • Does JSLint parse DOM functions?

    - by Paul
    I tried to use the parse() function of JSLint to parse three pieces of JavaScript code: function(b, c){var a = b + c; return a; } window.addEventListener('click', click_hanlder, true); document.documentElement.innerHTML; Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse(); var source = "something to parse";//replaced by the code above tree = parse(source); if (tree) { document.write(JSON.stringify(tree, ['key', 'name', 'message', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } } catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } ` The output: returns a correct tree. returns a tree with only one node of "window". crashes the browser. I'm wondering whether JSLint doesn't support DOM function.

  • use proxy from a list

    - by user1505181
    I am trying to write a program which neeeds to use a proxy 3 times then move onto the next proxy in a list and so on. the user will enter their proxy list into a list/textfile and the program will use the first in the list and then carry on through the list until it gets to the end. How do i get the proxy details from the list and use them using httpwebrequest? i have no problem using a proxy if i set it within the code but dont know how to get it to work through the list basically it is like this: user enters a list of proxies into a text file program uses first proxy in list 3 times then moves onto next. this repeats until finished.

  • Visit neighbor of a position in a 2d-array

    - by Martin
    I have the following two dimensional array: static int[,] arr = new int[5, 5] { { 00, 00, 00, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 00, 01, 00 }, }; I have to a implement a method called Hit(int x, int y). When we hit a 0 in the array (i.e. Hit(0, 0), Hit(1, 1), but not Hit(3, 0)) I would like all the adjacent zeros to the zero we hit to be incremented by 10. So if I call Hit(1, 1), the array should become the following. static int[,] arr = new int[5, 5] { { 10, 10, 10, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 10, 01, 00 }, }; Any idea how I could implement that? It sounds to me like a Depth First Search/Recursive sort-of algorithm should do the job, but I haven't been able to implement it for an 2d array. Thanks for the help!

  • Why must I rewind IteratorIterator

    - by chris
    $arrayIter = new ArrayIterator( array(1, 2) ); $iterIter = new IteratorIterator($arrayIter); var_dump($iterIter->valid()); //false var_dump($arrayIter->valid()); //true If I first call $iterIter-rewind(), then $iterIter-valid() is true. I'm curious why it requires that rewind() be called. I imagine there's good reason for it, but I would have expected it to simply start iteration at whatever state it's inner iterator is in, and leave it as an option to rewind before beginning iteration. calling next() also seems to put it in a "valid" state(although it advances to the next position, suggesting it was previously at the first position). $arrayIter = new ArrayIterator(array(1,2)); $iterIter = new IteratorIterator($arrayIter); $iterIter->next(); var_dump($iterIter->valid()); Again, I'm curious why I need to call rewind(), despite the inner iterator being in a valid state.

  • Is it possible to use the ScalaTest BDD syntax in a JUnit environment?

    - by ebruchez
    I would like to describe tests in BDD style e.g. with FlatSpec but keep JUnit as a test runner. The ScalaTest Quick Start does not seem to show any example of this: http://www.scalatest.org/getting_started_with_junit_4 I first tried naively to write tests within @Test methods, but that doesn't work and the assertion is never tested: @Test def foobarBDDStyle { "The first name control" must "be valid" in { assert(isValid("name·1")) } // etc. } Is there any way to achieve this? It would be even better if regular tests can be mixed and matched with BDD-style tests.

  • Java BufferedReader behavior in CSV vs TXT file

    - by Gabriel
    If i try to read a CSV file called csv_file.csv. The problem is that when i read lines with BufferedReader.readLine() it skips the first line with months. But when i rename the file to csv_file.txt it reads it allright and it's not skipping the first line. Is there an undocumented "feature" of BufferedReader that i'm not aware? Example of file: Months, SEP2010, OCT2010, NOV2010 col1, col2, col3, col4, col5 aaa,,sdf,"12,456",bla bla bla, xsaffadfafda and so on, and so on, "10,00", xxx, xxx The code: FileInputStream stream = new FileInputStream(UploadSupport.TEMPORARY_FILES_PATH+fileName); BufferedReader br = new BufferedReader(new InputStreamReader(stream, "UTF-8")); String line = br.readLine(); String months[] = line.split(","); while ((line=br.readLine())!=null) { /*parse other lines*/ }

I tried installing individual dependency gems first from a locally downloaded files but I soon found out that there is no end to the rabbit hole :-) I also found out that there are circular dependencies that break even this tedious method. There must be a better way!

  • does the condition after && always get evaluated

    - by brett
    I have this if statement that tests for the 2 conditions below. The second one is a function `goodToGo() so I want to call it unless the first condition is already true $value = 2239; if ($value < 2000 && goodToGo($value)){ //do stuff } function goodToGo($value){ $ret = //some processing of the value return $ret; } My question is about the 2 if conditions $value < 2000 && goodToGo($value). Do they both get evaluated or does the second one only get evaluated when the first one is true? In other words, are the following 2 blocks the same? if($value < 2000 && goodToGo($value)) { //stuff to do } if($value < 2000) { if (goodToGo($value)){ //stuff to do } }

  • Recommendations with hierarchical data on non-relational databases?

    - by Luki
    I'm developing an web application that uses a non-relational database as a backend (django-nonrel + AppEngine). I need to store some hierarchical data (projects/subproject_1/subproject_N/tasks), and I'm wondering which pattern should I use. For now I thought of: Adjacency List (store the item's parent id) Nested sets (store left and right values for the item) In my case, the depth of nesting for a normal user will not exceed 4-5 levels. Also, on the UI, I would like to have a pagination for the items on the first level, to avoid to load too many items at the first page load. From what I understand so far, nested sets are great when the hierarchy is used more for displaying. Adjacency lists are great when editing on the tree is done often. In my case I guess I need the displaying more than the editing (when using nested sets, even if the display would work great, the above pagination could complicate things on editing). Do you have any thoughts and advice, based on your experience with the non-relational databases?

  • Issues running python scripts in Command Prompt (Specifically with command line arguments)?

    - by dmanatunga
    I am trying to run my python scripts in DOS without calling python.exe first. I am specifically doing this in relation to running django-admin.py. I have C:\Python26 and C:\Python26\Scripts in my PATH. However, if I try running django-admin.py by doing: django-admin.py startproject helloworld I get the message: Type 'django-admin.py help' for usage. Now, after some experimentation, I realized the problem is that the secondary arguments to these scripts are not being passed for some reason, since I tried it with a some other python scripts I have. I know I could avoid this problem by simply doing: python C:\Python26\Scripts\django-admin.py startproject helloworld But I know it should be possible to run the first command only and get it to work, because I had it working before. I've looked everywhere, and not many places have been helpful so any idea would be useful for me at this point.

    - by Ajay Pandey
    i have a UITextView object which i have created in interface builder with it's hidden property unmarked.Now i want this textView to be invisible when my application launches and first view appears.Further i want it to be displayed when a particular method is called.Now this is what i have written in view did load [mTextView setHidden:YES]; self.mTextView=[[UITextView alloc] init]; it hides the textView ats the first view appears but when my desired method is called and i write [mTextView setHidden:NO]; it does not show it again.. Is it like we cant change the appearance of a textView once it is assigned because after assigning memory as self.mTextView=[[UITextView alloc] init]; and then writing [mTextView setHidden:YES]; it does not hide textView in viwDidLoad either.....

  • How to putExtra() in Searchable Dictionary Example

    - by sirlunchalot
    Hi, based on the Searchable Dictionary sample I tried to put extra data to a different activity. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Spinner distance = (Spinner) findViewById(R.id.distanceSpinner); ArrayAdapter<CharSequence> adapterDistance = ArrayAdapter.createFromResource( this, R.array.distance, android.R.layout.simple_spinner_item); adapterDistance.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); distance.setAdapter(adapterDistance); Intent intent = getIntent(); if (Intent.ACTION_VIEW.equals(intent.getAction())) { // handles a click on a search suggestion; launches activity to show word mapIntent = new Intent(this, Map.class); mapIntent.setData(intent.getData()); mapIntent.putExtra("Distance", distance.getSelectedItemPosition()); startActivity(mapIntent); finish(); } } In my Map Class Distance is always zero because distance.getSelectedItemPostion() gets the initialized value. How can I putExtra data with a click on a search suggestion? Thanks

  • Using DAO's or static methods in Domain Object with nHibernate

    - by mickyjtwin
    I am using nHibernate for the first time, and after alot of reading/researching, plus looking at other projects done with nHibernate, have seen a couple of implementation practices. I am looking for opinions about which would be best to use and why. Essentially the two methods are as follows: Using Data Access Objects and a DAO Factory. Example usage: INotificationListDAO nListDAO = NHDaoFactory.GetNotificationListDAO(); NotificationList list = nListDAO.GetByListID(""); Use Static methods in the Domain Object. Example usage: NotificationList list = NotificationList.GetByListID(""); NHHelper.Session.Get(id); NHHelper.Session basically calls the NHibernateSessionManager.Instace.GetSessionFrom(""). While both look similar, it is more to do with best practice. From what I understand, the first option is more so if you are developing enterprise level applications, where my requirements are more for mid-range websites.

  • Problem with generic list and extension method(C#3.0)

    - by Newbie
    I have an issue. I am making an extension class for a Collection and it is generic.. like public static class ListExtensions { public static ICollection<T> Search<T>(this ICollection<T> collection, string stringToSearch) { ICollection<T> t1=null; foreach (T t in collection) { Type k = t.GetType(); PropertyInfo pi = k.GetProperty("Name"); if (pi.GetValue(t,null).Equals(stringToSearch)) { t1.Add(t); } } return t1; } } But I cannot add items to t1 as it is declared null. Error: object reference not set to an instance of the object. I am calling the method like List<TestClass> listTC = new List<TestClass>(); listTC.Add(new TestClass { Name = "Ishu", Age = 21 }); listTC.Add(new TestClass { Name = "Vivek", Age = 40 }); listTC.Add(new TestClass { Name = "some one else", Age = 12 }); listTC.Search("Ishu"); And the test class is public class TestClass { public string Name { get; set; } public int Age { get; set; } } Using : (C#3.0) & Framework - 3.5 Thanks

  • C segmentation fault before/during return statement

    - by wolfPack88
    I print the value that I'm returning right before my return statement, and tell my code to print the value that was returned right after the function call. However, I get a segmentation fault after my first print statement and before my second (also interesting to note, this always happens on the third time the function is called; never the first or the second, never fourth or later). I tried printing out all of the data that I'm working on to see if the rest of my code was doing something it maybe shouldn't, but my data up to that point looks fine. Here's the function: int findHydrogen(struct Amino* amino, int nPos, float* diff, int totRead) { struct Atom* atoms; int* bonds; int numBonds; int i; int retVal; int numAtoms; numAtoms = (*amino).numAtoms; atoms = (struct Atom *) malloc(sizeof(struct Atom) * numAtoms); atoms = (*amino).atoms; numBonds = atoms[nPos].numBonds; bonds = (int *) malloc(sizeof(int) * numBonds); bonds = atoms[nPos].bonds; for(i = 0; i < (*amino).numAtoms; i++) printf("ATOM\t\t%d %s\t0001\t%f\t%f\t%f\n", i + 1, atoms[i].type, atoms[i].x, atoms[i].y, atoms[i].z); for(i = 0; i < numBonds; i++) if(atoms[bonds[i] - totRead].type[0] == 'H') { diff[0] = atoms[bonds[i] - totRead].x - atoms[nPos].x; diff[1] = atoms[bonds[i] - totRead].y - atoms[nPos].y; diff[2] = atoms[bonds[i] - totRead].z - atoms[nPos].z; retVal = bonds[i] - totRead; bonds = (int *) malloc(sizeof(int)); free(bonds); atoms = (struct Atom *) malloc(sizeof(struct Atom)); free(atoms); printf("2 %d\n", retVal); return retVal; } } As I mentioned before, it works fine the first two times I run it, the third time it prints the correct value of retVal, then seg faults somewhere before it gets to where I called the function, which I do as: hPos = findHydrogen((&aminoAcid[i]), nPos, diff, totRead); printf("%d\n", hPos);

  • ssrs 2008 programmatically add tables rows

    - by davethecoder
    Above is how my report looks, the part in yellow in hidden, and is only shown when the user clicks the + icon on the [name]. the result is basically the percentage difference from the Past [X] - [TERM] i.e there is a dropdown with, [weeks, months, days, hours] and a textbox of qty. so choosing qty = 4 and term = weeks will delivery a result set spread over 4 weeks based on the parent result sets date range and name ID I wish to populate here the number of rows, dependant on the value set by the user and the data will be from a dataset. Is it possible to dynamically add more sub rows ( like on row data bound ) if my first row is ID 123 [name], is it possible to send this value [123] to a dataset in order that all subrows are only relevant to the name with ID of 123? this is my first bash at SSRS so please no half cut answers, that just lead to more questions about the answer given :-) if this makes sense. Thanks

  • heirarchial data from self referencing table in tree form

    - by Beta033
    Ii looks like this has been asked and answered in all the simple cases, excluding the one that i'm having trouble with. I've tried using a recursive CTE to generate this, however maybe a cursor would be better? or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

  • Application disappears after starting - C++ linking managed code dll

    - by Axarydax
    Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP3 x86, and all applications linking managed code dll do not work. After starting the .exe seemingly nothing happens, no window pops up, no memory gets eaten, no task shows in task manager, nothing, nada. Event log is empty, everything is just as if the application returned to the OS right after the start. I am at loss about this, I really don't know how should I start even debugging this problem. I don't want to install VS2010 and everything onto a Windows XP box, I'd like to try something less time intensive first. This all is happening just to native C++ apps that link managed c++ DLL. Pure managed C# apps do work. Pure native C++ apps do work.

  • How to handle server-client requests

    - by Layne
    Currently I'm working on a Server-Client system which will be the backbone of my application. I have to find the best way to send requests and handle them on the server-side. The server-side should be able to handle requests like this one: getPortfolio -i 2 -d all In an old project I decided to send such a request as string and the server application had to look up the first part of the string ("getPortfolio"). Afterwards the server application had to find the correct method in a map which linked the methods with the the first part of the string ("getPortfolio"). The second part ("-i 2 -d all") got passed as parameter and the method itself had to handle this string/parameter. I doubt that this is the best solution in order to handle many different requests.

  • How to use C# nested structures to access tree of data

    - by zotty
    I'm importing some XML to C#, and want to be able to access data from the XML in the form of what I think is a nested structure. (I may be wrong!) What I have in my XML is in the following form: <hardwareSettings initial="true> <cameraSettings width="1024" height="768" depth="8" /> <tiltSettings theta="35" rho="90"> </hardwareSettings> I can import each setting alright, so I have them all in individual ints, but I would like to be able to access it in the form int x=hardwaresettings.camerasettings.width; int rho=hardwaresettings.tiltsettings.rho; I've tried various arrangements of structs within structs, but I don't seem able to cast a new object (hardwaresettings) that contains the appropriate children (camerasettings.width & tiltsettings.rho). Sorry if I'm not using the right lingo... I'm reading myself in circles here!

  • Does anyone actually use the phrase DHTML anymore?

    - by lafoaug
    I'm not sure if this is exactly appropriate but I have what I think is a interesting question. Does anyone actually use the phrase DHTML anymore in a professional environment? I came across the the word the other day for the first time in years and shuddered at the thought of it. To me the acronym Dynamic HTML just sounds so 1999, it brings me back to the days when I first discovered programming and web development and thought it was awesome to have scripts which modified the status bar and made things fly around the page. I for one have never used the phrase recently and would never dream of saying it in a professional environment to clients or colleges as I feel there is an amateur and dated stigma attached to it. What are your thoughts?

  • What should I do with an over-bloated select-box/drop-down

    - by Tristan Havelick
    All web developers run into this problem when the amount of data in their project grows, and I have yet to see a definitive, intuitive best practice for solving it. When you start a project, you often create forms with tags to help pick related objects for one-to-many relationships. For instance, I might have a system with Neighbors and each Neighbor belongs to a Neighborhood. In version 1 of the application I create an edit user form that has a drop down for selecting users, that simply lists the 5 possible neighborhoods in my geographically limited application. In the beginning, this works great. So long as I have maybe 100 records or less, my select box will load quickly, and be fairly easy to use. However, lets say my application takes off and goes national. Instead of 5 neighborhoods I have 10,000. Suddenly my little drop-down takes forever to load, and once it loads, its hard to find your neighborhood in the massive alphabetically sorted list. Now, in this particular situation, having hierarchical data, and letting users drill down using several dynamically generated drop downs would probably work okay. However, what is the best solution when the objects/records being selected are not hierarchical in nature? In the past, of done this with a popup with a search box, and a list, but this seems clunky and dated. In today's web 2.0 world, what is a good way to find one object amongst many for ones forms? I've considered using an Ajaxifed search box, but this seems to work best for free text, and falls apart a little when the data to be saved is just a reference to another object or record. Feel free to cite specific libraries with generic solutions to this problem, or simply share what you have done in your projects in a more general way
