• codeigniter and form action trailing / issue??

  - by alex

  Hi, I am having a bit of an issue with the way CI is dealing with /. In a regular form i notice that the following form action didn't work action="mydomain.com/ci-controller/login/" but this one does work action="mydomain.com/ci-controller/login" Strange but he it worked. But now i need this from a iframe, i the iframe i have a login form which sets the parents url to mydomain.com/ci-controller/login, but i get the same error as it was calling mydomain.com/ci-controller/login/ Could my problem be that the call from the iframe adds a trailing / which is not visible?? Any thoughts

• c++: use a #define in printf?

  - by John

  I was wanting to use a constant of some kind for the application ID (so I can use it in printf). I had this: #define _APPID_ "Hello World!" And then the simple printf, calling it into %s (string). It put this out: simple.cpp:32: error: cannot convert ‘_IO_FILE*’ to ‘const char*’ for argument ‘1’ to ‘int printf(const char*, ...)’ What would I use to define the application ID to use in printf? I tried: static const char _APPID_[] = "Hello World"` but it didn't work, same error I think.

• Jquery Conflicts with another Jquery Library

  - by Johangsl

  I am currently trying to implement a jquery slider into a joomla website. I already implemented NoConflict(); so that it doesn't step into joomla. And it works, BUT for another reason wich I do not understand it enters another jquery file called jsloader.js of a plugin I use for picture gallery display. I suppose all the module jquery files get preloaded before the one im calling inside the template. it enters the function() in the jsloader.js instead of the one in my jquery file. How Can I force it to enter my jquery file instead of other

• Excel + Web Data

  - by user348152

  I've spent hours scouring the net for anything to do with VBA calling data from the web in excel and nothing provides a tutorial on how to do so, only complicated examples un-related to what I want to do. I want to pull data from either a .html or .xml site, doesn't matter, via Excel and find specific points in that data. I can find specific points but don't know how to get the data or scroll through multiple lines. I've done this exact sort of thing in mIRC (sort of C code). http://eve-central.com/home/quicklook.html?typeid=438 http://api.eve-central.com/api/quicklook?typeid=438 Those are two examples, using roughly the same data I'd like to retrieve. It'd be FAR more specific with at most 100 or so different values. I'd like to be TAUGHT how to do it, not given the code to do it, or if you must explain each part with comments in-depth please. Thanks Nick

• callin' c from lua crashes while reallocating

  - by mkind

  hi folks, i got a crazy error within that for-loop matr=realloc(matr, newmax*sizeof(matr*)); for (i=0; i<newmax; i++){ matr[i]=realloc(matr[i], newmax*sizeof(int)); } matr is a multi-dimension array: int **matr. i need to resize column and row. first line resizes column and the for-loop resizes every row. it worked fine in c. now im working on a library for lua and it crashs here. compilin' works fine as well. but calling from lua crashs with lua: malloc.c:3552: mremap_chunk: Assertion `((size + offset) & (mp_.pagesize-1)) == 0' failed. i have no damn idea since it's working fine using it in c.

• python mock side_effect or return_value dependent on call_count

  - by user18380

  To test a polling function I want to mock the calling of a sub function so that the first time it is called it will fail, and the second time it is called it will succeed. Here's a very simplified version of it: poll_function(var1): value = sub_function(var1) # First call will return None while not value: time.sleep(POLLING_INTERVAL) value = sub_function(var1) # A subsequent call will return a string, e.g "data" return value Is this possible to do with a Mock object from the mock framework? I know Mock objects have a call_count attribute I should be able to use somehow. Right now I've solved it by creating a custom mock object that I use to monkey patch sub_function(), but I feel there should be a better less verbose way of doing it: def test_poll(): class MyMock(object): def __init__(self, *args): self.call_count = 0 def sub_function(self, *args, **kwargs): if self.call_count > 1: return "data" else: self.call_count += 1 return None my_mock = MyMock() with patch('sub_function', my_mock.sub_function): ok_(poll_function())

• is there a limit on the number of times navigator.geolocation.getCurrentPostion can be called ?

  - by Raja

  Hi all, This is may not be a true programming question but deals with geolocation Api, hence hoping StackOverflow is the right place for this. I'm calling the navigator.geolocation.getCurrentPosition at every 3 seconds interval. After 10-15 tries the responses stop. So i'm wondering is there a limit on the number of calls being made, Or is it because i'm testing it with a desktop and hence instead of giving back the same response each time the API is waiting for a change of location. Anyone has any experiences to share ? Thanks

• Passing values for multi-value parameter in SSRS query string

  - by Andy Xufuris

  I have two reports built using SSRS 2005. The first report is set to navigate to the second when a specific field is clicked. There is a multi-value parameter on the second report. I need to pass multiple values for this parameter in the URL query string when calling this report. Is there a way to pass multiple values for a parameter in the query string of a report? Or can you pass a parameter that will cause the Select All value to be selected?

• How to link Delphi with C++?

  - by CyberShadow

  cpp.cpp extern "C" char* GetText() { return "Hello, world!"; } delphi.dpr {$APPTYPE CONSOLE} {$LINK 'cpp.obj'} function _GetText: PChar; cdecl; external; begin WriteLn(_GetText); end. I can't get this to work, no matter what I try. I tried various calling conventions, playing with underscores. even creating a .c wrapper for the .cpp code (but then the .c wrapper doesn't "see" any .cpp symbols). I'm about to give up and use DLLs. Any suggestions?

• jQuery ajax() and cakePHP urls

  - by Pickledegg

  I'm trying to call the 'tariff' action of my 'countries' controller using jQuery ajax() and pass it a country name in the following format: /countries/tariff/countryname however, with the following code ( set to GET ), it is calling this with the get '?' added: /countries/tariff/?countryname $(document).ready(function(){ $('#CountriesIndexForm select').change(function(){ $.ajax({ type: "GET", url: "/countries/tariff/", data: escape($(this).val()), success: function(html){ $(this).parent().next('div').html(html); } }); }); }); I understand its because the type: is set to GET, but is there a fix for this?

• IDisposable, does it really matter

  - by adrianm

  Coming from C/C++ a long time ago I still have a habit of ensuring that all resources are cleaned up correctly. I always ensure Dispose is called on IDisposable classes and implement Dispose patterns in my classes containing disposable objects. However, in my environment I'm more or less the only one doing this. Others just don't understand what I'm doing and think my code is more difficult to understand. They just create database connections, open streams etc without calling Close or Dispose. Sometimes they set a local or member variable to "Nothing" at the end of a method (guess their background). My problem is that their code works just as well as mine. Code that over time creates thousands of database connection objects just works. So, ignoring any arguments about code correctness, following guidelines etc, does IDiposable really matter? Has anyone actually ran out of resources from not Disposing objects?

• Writing Strings to files in python

  I'm getting the following error when trying to write a string to a file in pythion: Traceback (most recent call last): File "export_off.py", line 264, in execute save_off(self.properties.path, context) File "export_off.py", line 244, in save_off primary.write(file) File "export_off.py", line 181, in write variable.write(file) File "export_off.py", line 118, in write file.write(self.value) TypeError: must be bytes or buffer, not str I basically have a string class, which contains a string: class _off_str(object): __slots__ = 'value' def __init__(self, val=""): self.value=val def get_size(self): return SZ_SHORT def write(self,file): file.write(self.value) def __str__(self): return str(self.value) Furthermore, I'm calling that class like this: def write(self, file): for variable in self.variables: variable.write(file) I have no idea what is going on. I've seen other python programs writing strings to files, so why can't this one? Thank you very much for your help.

• Running javascript in AJAX loaded DIV

  - by WiseDonkey

  I have page loading, via AJAX a PHP page into a div. In turn, this loaded page has it's own javascript and AJAX loaded div. Reason is to allow user to select data alter data within loaded data. I'm trying to do this without the help of JSON or such to communicate between JS and PHP. I'm guessing the parent calling page has already loaded the javascript, and the AJAX loaded content can't access that? (I've tried running the JS into the AJAX loaded content as well) If so, is there anyway to access that?

• codingstyle "blanking after open and before close brackets"

  - by Oops

  I really like the "blanking after open and before close brackets"-codingstyle in modern codes Java/C#/C++ . e.g. calling a function: foo(myparam); // versus foo( myparam ); Do you have a better name for this codingstyle? where does it come from? Do you like it either, what is the reason for you to use it or not use it? a few years ago people said "you are blanking" if one has used too much blank space characters in a forumspost or email. many thanks in advance regards Oops edit: two cons, any pros out there?

• Explicit constructor still has default values even though a default constructor is not invoked.

  - by Phoenix

  According to my understanding a default constructor initializes the state of the object to default values, so if i provide an explicit no-arg public constructor like this then how are the values of d and e still getting initialized to zero because in this case the default constructor is not invoked. public class B extends A{ private int d; private int e; public B() { System.out.println(d); System.out.println(e); } } EDIT:: The only thing default constructor does is call to super() then how come if i have a explicitly mentioned a constructor here and A has a protected variable say c which is initialized to 17 in its constructor. Should I not be explicitly calling super() to be able to see that change since I'm using my own constructor ? Why is B still getting the value of 17 through inheritance ?

• Explicitly persist states in Workflow 4.0 rather than everything.

  - by jlafay

  I have ran into an issue with my SQL instance store attached to a WorkflowApplication that is running. When I exit my application I'm calling an Unload() on the WF app to persist it. I didn't think about it during design time, but it does makes sense, it's persisting an arg that was passed in to the WorkflowApplication constructor when instanced. When the application runs, everything in the workflow works as expected. When I call Unload() I get an unhandled exception that states that the arg is not serializable and needs [DataContractAttribute]. What's passed into the workflow is my applications custom logger object that I wrote so that the WF can log to disk in a uniform way that I prefer. How do I prevent the workflow app from persisting this one argument and persist everything else? I'm sure something can be done with extensions but I'm having a hard time finding info on them or finding persistence examples for my scenario.

• How can I use multithreading in a Windows Forms application to update a progress bar?

  - by Steve Syfuhs

  There are two objects. The Windows Form with a button and a progress bar, and another object that handles an algorithm. In the algorithm object there is an event, and a property. The event is ProgressChanged, and the property is Progress (which is an int). In the calling window, the button starts off a set of steps in the algorithm object. As each step (or substeps) occurs, the ProgressChanged event fires, and in the window there is an event handler that essentially increments the progress bar relative to the Progress property. The problem I am running into is that because the algorithm has a possibility (and high liklihood) of running a relatively long time, I need to move it into it's own background thread and push the event back up to the window. My issue is that I'm not completely sure what I'm doing when it comes to multi-threading. I've looked at Control.Invoke and I'm a little lost. Can someone point me in the right direction?

• WebView not responding when called from a method

  - by AragornSG

  I have an app with tabbar and webview. I'm trying to make the app come back to default url each time user taps the bar. Right now I'm intercepting taps and launching a method, however it's not affecting my webview. The same syntax for calling webview from awakeFromNib works, so I don't have a clue what's up. I suspect it's something to do with how I call the method, but I don't know what. Here is the code: #import "SecondViewController.h" @implementation SecondViewController - (void)awakeFromNib { NSString *loadURL = [NSString stringWithFormat:@"http://pageurl"]; // [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:loadURL]]]; SecondViewController *ptr = [[SecondViewController alloc] init]; [ptr goToPage]; } - (void) goToPage { NSLog(@"go to page"); NSString *newURL = [NSString stringWithFormat:@"http://pageurl"]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks fot your help!

• Inconsistent Behavior From Declared DLL Function

  - by Steven

  Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

• Can one extract model fit parameters after a ggplot stat_smooth call?

  - by Alex Holcombe

  Using stat_smooth, I can fit models to data. E.g. g=ggplot(tips,aes(x=tip,y=as.numeric(unclass(factor(tips$sex))-1))) +facet_grid(time~.) g=g+ stat_summary(fun.y=mean,geom="point") g=g+ stat_smooth(method="glm", family="binomial") I would like to know the coefficients of the glm binomial fits. I could re-do the fit with dlply and get the coefficients with ldply, but I'd like to avoid such duplication. Calling str(g) reveals the hierarchy of objects that ggplot creates, perhaps there's some way to get to the coefficients through that?

• How do I cancel a text selection after the initial mousedown event?

  - by cwillu-gmail

  I'm trying to implement a pop-up menu based on a click-and-hold, positioned so that a (really) slow click will still trigger the default action, and with the delay set so that a text-selection gesture won't usually trigger the menu. What I can't seem to do is cancel the text-selection in a way that doesn't prevent text-selection in the first place: returning false from the event handler (or calling $(this).preventDefault()) prevents the user from selecting at all, and the obvious $().trigger('mouseup') doesn't doesn't do anything with the selection at all. This is in the general context of a page, not particular to a textarea or other text field. e.stopPropogation() doesn't cancel text-selection. I'm not looking to prevent text selections, but rather to veto them after some short period of time, if certain conditions are met.

• python input for itertools.product

  - by user364249

  Looking for a way to simulate nested loops (or a cartesian product) i came across the itertools.product function. i need a function or piece of code that receive a list of integers as input and returns a specific generator. example: input = [3,2,4] - gen = product(xrange(3),xrange(2),xrange(4)) or input = [2,4,5,6] - gen = product(xrange(2),xrange(4),xrange(5),xrange(6)) as the size of the lists varies i am very confused in how to do that without the need of a lot of precoding based on a crazy amount of ifs and the size of the list. also is there a difference in calling product(range(3)) or product(xrange(3))?
