  • Php is stripping one letter "g" from my rtrim function but not other chars

    - by Chase
    I'm trying to trim some youtube URLs that I am reading in from a playlist. The first 3 work fine and all their URLs either end in caps or numbers but this one that ends in a lower case g is getting trimmed one character shorter than the rest. for ($z=0; $z <= 3; $z++) { $ythref2 = rtrim($tubeArray["feed"]["entry"][$z]["link"][0]["href"], '&feature=youtube_gdata'); The URL is http://www.youtube.com/watch?v=CuE88oVCVjg&feature=youtube_gdata .. and it should get trimmed down to .. http://www.youtube.com/watch?v=CuE88oVCVjg but instead it is coming out as http://www.youtube.com/watch?v=CuE88oVCVj. I think it may be the ampersand symbol but I am not sure.

  • Mail "Can't continue" for a AppleScript function

    - by Paul J. Lucas
    I'm trying to write an AppleScript for use with Mail (on Snow Leopard) to save image attachments of messages to a folder. The main part of the AppleScript is: property ImageExtensionList : {"jpg", "jpeg"} property PicturesFolder : path to pictures folder as text property SaveFolderName : "Fetched" property SaveFolder : PicturesFolder & SaveFolderName tell application "Mail" set theMessages to the selection repeat with theMessage in theMessages repeat with theAttachment in every mail attachment of theMessage set attachmentFileName to theAttachment's name if isImageFileName(attachmentFileName) then set attachmentPathName to SaveFolder & attachmmentFileName save theAttachment in getNonexistantFile(attachmentPathName) end if end repeat end repeat end tell on isImageFileName(theFileName) set dot to offset of "." in theFileName if dot > 0 then set theExtension to text (dot + 1) thru -1 of theFileName return theExtension is in ImageExtensionList end if return false end isImageFileName When run, I get the error: error "Mail got an error: Can’t continue isImageFileName." number -1708 where error -1708 is: Event wasnt handled by an Apple event handler. However, if I copy/paste the isImageFileName() into another script like: property imageExtensionList : {"jpg", "jpeg"} on isImageFileName(theFileName) set dot to offset of "." in theFileName if dot > 0 then set theExtension to text (dot + 1) thru -1 of theFileName return theExtension is in ImageExtensionList end if return false end isImageFileName if isImageFileName("foo.jpg") then return true else return false end if it works fine. Why does Mail complain about this?

  • How to check function parameters in Go

    - by deamon
    Guava Preconditions allows to check method parameters in Java easily. public void doUsefulThings(Something s, int x, int position) { checkNotNull(s); checkArgument(x >= 0, "Argument was %s but expected nonnegative", x); checkElementIndex(position, someList.size()); // ... } These check methods raise exceptions if the conditions are not met. Go has no exceptions but indicates errors with return values. So I wonder how an idiomatic Go version of the above code would look like.

  • st-ordering library function?

    - by chang
    I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

  • Passing BLOB/CLOB as parameter to PL/SQL function

    - by Ula Krukar
    I have this procedure i my package: PROCEDURE pr_export_blob( p_name IN VARCHAR2, p_blob IN BLOB, p_part_size IN NUMBER); I would like for parameter p_blob to be either BLOB or CLOB. When I call this procedure with BLOB parameter, everything is fine. When I call it with CLOB parameter, I get compilation error: PLS-00306: wrong number or types of arguments in call to 'pr_export_blob' Is there a way to write a procedure, that can take either of those types as parameter? Some kind of a superclass maybe?

  • What perl function to use?

    - by user301087
    I'm setting something up to SSH out to several servers in 'batches'. I basically want to maintain 5 connections at a time, and when one finishes open up another (following an array of server IPs). I'm wondering for something like this should I be using fork()? If so, what logic can I use to ensure that the I maintain 5 children at a time?

  • Problem with LSParseDateTime function on server

    - by Saul
    When I run this test code on my development machine it works as expected. CF9.01 I am in europe using euro date format so 10/09/1957 is 10th Sept 1957. <cfset testDate="10/09/1957"> <cfoutput> Initial string = "#testDate#"<br> LSparsedatetime output = #lsparsedatetime(session.form.patientDOB)#<br> parsedatetime output = #parsedatetime(session.form.patientDOB)# </cfoutput> Output on test machine is Initial string = "10/09/1957" LSparsedatetime output = {ts '1957-09-10 00:00:00'} parsedatetime output = {ts '1957-10-09 00:00:00'} Same code , output on live server is Initial string = "10/09/1957" LSparsedatetime output = {ts '1957-10-09 00:00:00'} parsedatetime output = {ts '1957-10-09 00:00:00'} Server OS is Windows Web Server 2008 R2. I checked Control panel date and time setting and it is correctly set to London. Web server is IIS7 but I don't think that would affect anything? IN region and Language, location is set to United Kingdom and in Administrative (change system locale ) it is also correct as English (United Kingdom)

  • Pros and Cons of Different macro function / inline methods in C

    - by Robert S. Barnes
    According to the C FAQ, there are basically 3 practical methods for "inlining" code in C: #define MACRO(arg1, arg2) do { \ /* declarations */ \ stmt1; \ stmt2; \ /* ... */ \ } while(0) /* (no trailing ; ) */ or #define FUNC(arg1, arg2) (expr1, expr2, expr3) To clarify this one, the arguments are used in the expressions, and the comma operator returns the value of the last expression. or using the inline declaration which is supported as an extension to gcc and in the c99 standard. The do { ... } while (0) method is widely used in the Linux kernel, but I haven't encountered the other two methods very often if at all. I'm referring specifically to multi-statement "functions", not single statement ones like MAX or MIN. What are the pros and cons of each method, and why would you choose one over the other in various situations?

  • Calling a C function in a DLL with enum parameters from Delphi

    - by dommer
    I have a third-party (Win32) DLL, written in C, that exposes the following interface: DLL_EXPORT typedef enum { DEVICE_PCI = 1, DEVICE_USB = 2 } DeviceType; DLL_EXPORT int DeviceStatus(DeviceType kind); I wish to call it from Delphi. How do I get access to the DeviceType constants in my Delphi code? Or, if I should just use the values 1 and 2 directly, what Delphi type should I use for the "DeviceType kind" parameters? Integer? Word?

  • super function doesn't work inside a maya python module

    - by sfjedi
    Somehow, this works fine in the Maya/Python script editor, but fails when it's inside of my module code. Anyone have any ideas? class ControlShape(object): def __init__(self, *args, **kwargs): print 'Inside ControlShape...' class Cross(ControlShape): def __init__(self, *args, **kwargs): print 'Entering Cross...' super(Cross, self).__init__(*args, **kwargs) print 'Leaving Cross...' x = Cross() This gives me a TypeError: super(type, obj): obj must be an instance or subtype of type.

  • how do call a polymorphic function from an agnostic function?

    - by sds
    I have a method foo void foo (String x) { ... } void foo (Integer x) { ... } and I want to call it from a method which does not care about the argument: void bar (Iterable i) { ... for (Object x : i) foo(x); // this is the only time i is used ... } the code above complains that that foo(Object) is not defined and when I add void foo (Object x) { throw new Exception; } then bar(Iterable<String>) calls that instead of foo(String) and throws the exception. How do I avoid having two textually identical definitions of bar(Iterable<String>) and bar(Iterable<Integer>)? I thought I would be able to get away with something like <T> void bar (Iterable<T> i) { ... for (T x : i) foo(x); // this is the only time i is used ... } but then I get cannot find foo(T) error.

  • SSRS Multilookup Function for Names with Comma Separation

    - by AliceAyers292
    I would like to put the following in a a multilookup drop-down in reporting services: "Smith, John", "Jones, Tim", "Kelly, Andy" The comma separating the first and last name prevents the multilookup from working correctly. I am also unable to use ticks (' or ") in reporting service to keep the separating comma from working like a multilookup comma that separates the fields I want to select from. Is there a way to keep the comma in the names while still allowing multilookup? Any help would be much appreciated. Thank you!

  • Python New-style Classes and the Super Function

    - by sfjedi
    This is not the result I expect to see: class A(dict): def __init__(self, *args, **kwargs): self['args'] = args self['kwargs'] = kwargs class B(A): def __init__(self, *args, **kwargs): super(B, self).__init__(args, kwargs) print 'Instance A:', A('monkey', banana=True) #Instance A: {'args': ('monkey',), 'kwargs': {'banana': True}} print 'Instance B:', B('monkey', banana=True) #Instance B: {'args': (('monkey',), {'banana': True}), 'kwargs': {}} I'm just trying to get classes A and B to have consistent values set. I'm not sure why the kwargs are being inserted into the args, but I'm to presume I am either calling init() wrong from the subclass or I'm trying to do something that you just can't do. Any tips?

  • Accessing a Class Member from a First-Class Function

    - by dbyrne
    I have a case class which takes a list of functions: case class A(q:Double, r:Double, s:Double, l:List[(Double)=>Double]) I have over 20 functions defined. Some of these functions have their own parameters, and some of them also use the q, r, and s values from the case class. Two examples are: def f1(w:Double) = (d:Double) => math.sin(d) * w def f2(w:Double, q:Double) = (d:Double) => d * q * w The problem is that I then need to reference q, r, and s twice when instantiating the case class: A(0.5, 1.0, 2.0, List(f1(3.0), f2(4.0, 0.5))) //0.5 is referenced twice I would like to be able to instantiate the class like this: A(0.5, 1.0, 2.0, List(f1(3.0), f2(4.0))) //f2 already knows about q! What is the best technique to accomplish this? Can I define my functions in a trait that the case class extends? EDIT: The real world application has 7 members, not 3. Only a small number of the functions need access to the members. Most of the functions don't care about them.

  • PHP Round function

    - by Steve
    Is it possible to round a number where if it's 5 , just leave it , anything below 5 round down , anything above 5 round up? EX: 5 * 1.35 = 6.75 .... leave it 5.2 * 1.35 = 7.02 .... 7.00 5.5 * 1.35 = 7.56 .... 8.00 I've formatted with round($n,0, PHP_ROUND_HALF_UP) where $n is the product from the above calc , which leaves 6.75 but returns 7.02 for the next one. I also tried round($n,-1, PHP_ROUND_HALF_UP) which gives me the 7.00 on the second calc but then of course won't return a 6.75 for the first, instead it returns 680. This is a ticket markup calculation where the user enters the first number and is multiplied by the second. I actually remove the decimal because they don't want to see it, and they want this sort of customized rounding on the result. Thanks, Steve

However, when I move display_prompt to UI.h no "Hello111 " output is printed. anyone know how to solve that? Elad

  • Error in qsort function in Programming Pearls?

    Hello, is it just me or this code in Programming Pearls is wrong (quicksort wants 2 const voids, no?) If so, is my solution right? Apologies, just learning... int wordncmp(char *p, char* q) { int n = k; for ( ; *p == *q; p++, q++) if (*p == 0 && --n == 0) return 0; return *p - *q; } int sortcmp(char **p, char **q) { return wordncmp(*p, *q); } ... qsort(word, nword, sizeof(word[0]), sortcmp); Is this a solution? int sortcmp(const void *p, const void *q) { return wordncmp(* (char * const *) p, * (char * const *) q); }
