• Parse error: expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in ..?

  - by myaccount

  I tried to put an if statement inside an echo but this parse error came up, is it not possible to do that? should I use heredoc instead? echo "<input name='main_branch' type='radio' value='1' <?php if($restaurant['main_branch'] == 1) { echo "checked"; } ?> />Yes <input name='main_branch' type='radio' value='0' <?php if($restaurant['main_branch'] == 0) { echo " checked"; } ?> />No";

• Include code file into C#? Create library for others?

  - by Tomas

  Hi, I would like to know how can I embedd a code source file (if possible), something like that: class X { include "ClassXsource" } My second question - Can I build DLL or something like that for my colleagues to use? I need them to be able to call methods from my "part" but do not modify or view their content. Basically just use namespace "MyNamespace" and call its methods, but I have never done anything like that. Thanks

• C# - Does function get called for each iteration of a foreach loop?

  - by Robert W

  If I have functionality like the following - will ReturnParts() get called for each iteration in a foreach loop, or will it get called just the once? private void PrintParts() { foreach(string part in ReturnParts()) { // Do Something or other. } } private string[] ReturnParts() { // Build up and return an array. }

• syntax for generating an objectForKey from an array

  - by Brian

  I'm having success when I use this code to get a string from an array called "fileList": cell.timeBeganLabel.text = [[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]; so I expected the same code to generate the same string as a key for me in this: NSDictionary *stats = [thisRecordingsStats objectForKey:[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; cell.durationLabel.text = [stats objectForKey:@"duration"]; or this: NSDictionary *stats = [thisRecordingsStats objectForKey:@"%@",[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; Both build without error, and the log shows my data is there: but I'm getting a blank UILabel. Have I not written the dynamic key generator correctly?

• C++ WCHAR: Cannot allocate an array of constant size 0

  - by Rosarch

  I'm trying to create a WCHAR: LONG bufferSize = foo.bar() + 1; WCHAR wszBaz[bufferSize]; The compiler issues an error: error C2057: expected constant expression error C2466: cannot allocate an array of constant size 0 error C2133: 'wszBaz' unknown size What am I doing wrong? UPDATE: I added const but it still gives the same error: const LONG bufferSize = foo.bar() + 1; WCHAR wszBaz[bufferSize];

• What is the role of `while`-loops in computation expressions in F#?

  - by MizardX

  If you define a While method of the builder-object, you can use while-loops in your computation expressions. The signature of the While method is: member b.While (predicate:unit->bool, body:M<'a>) : M<'a> For comparison, the signature of the For method is: member b.For (items:seq<'a>, body:unit->M<'a>) : M<'a> You should notice that, in the While-method, the body is a simple type, and not a function as in the For method. You can embed some other statements, like let and function-calls inside your computation-expressions, but those can impossibly execute in a while-loop more than once. builder { while foo() do printfn "step" yield bar() } Why is the while-loop not executed more than once, but merely repeated? Why the significant difference from for-loops? Better yet, is there some intended strategy for using while-loops in computation-expressions?

• jQuery Code Only Fires On Hard Refresh?

  - by Rob Vanders

  The XFBML version of the Facebook Registration plugin only loads HTTPS. I need it to load HTTP so my form does not call a security error mismatch between domains. I wrote this code to get the SRC and rewrite it with out HTTPS It works fine on the first load, however on Chrome and Safari it only loads the first time and on HARD refreshes. It does not load on standard reloads or by pressing "enter" on the address bar. Here is the code $(window).load(function () { // Replace HTTPS with HTTP when frame has loaded $(".subscribe iframe").each(function(){ var source = $(this).attr("src"); //alert(source); var sourceNew = source.replace("https", "http"); // change https to http alert(sourceNew); $(this).attr("src", sourceNew); }); }); I have .HTACCESS set to disable server cache <Files *> Header set Cache-Control: "private, pre-check=0, post-check=0, max-age=0" Header set Expires: 0 Header set Pragma: no-cache </Files> What is causing this to not fire reliably? Thanks

• C# Why does calling an interface member from a class generate an error?

  - by Jack

  So I have an interface: interface IFoo { int Bar(); int this[int i] {get; set;} } And a class that derives from it class Foo : IFoo { public int IFoo.Bar() { //Implementation { public int IFoo.this[int i] { //Implementation } } Now, I try to do this: var fooey = new Foo(); int i = Fooey.Bar(); or this: int i = Fooey[4]; I would expect these to work properly. However, the compiler generates an error as if such members don't exist. Why is that? I am aware I can cast Foo as IFoo, but I am also aware that casting is costly to performance, which is often the reason to use interfaces in the first place. EDIT 1: These are the errors generated 'Foo' does not contain a definition for 'Bar' and no extension method 'Bar' accepting a first argument of type 'Foo' could be found (are you missing a using directive or an assembly reference?) "Cannot apply indexing to an expression of type 'Foo'"

• What is the "x = x || {}" technique in JavaScript - and how does it affect this IIFE?

  - by Micky Hulse

  First, a pseudo code example: ;(function(foo){ foo.init = function(baz) { ... } foo.other = function() { ... } return foo; }(window.FOO = window.FOO || {})); Called like so: FOO.init(); My question: What is the technical name/description of: window.FOO = window.FOO || {}? I understand what the code does... See below for my reason(s) for asking. Reason for asking: I'm calling the passed in global like so: ;(function(foo){ ... foo vs. FOO, anyone else potentially confused? ... }(window.FOO = window.FOO || {})); ... but I just don't like calling that lowercase "foo", considering that the global is called capitalized FOO... It just seems confusing. If I knew the technical name of this technique, I could say: ;(function(technicalname){ ... do something with technicalname, not to be confused with FOO ... }(window.FOO = window.FOO || {})); I've seen a recent (awesome) example where they called it "exports": ;(function(exports){ ... }(window.Lib = window.Lib || {})); I guess I'm just trying to standardize my coding conventions... I'd like to learn what the pros do and how they think (that's why I'm asking here)!

• Just seen a factory style object creating in JavaScript (without literals). What else do I need to k

  - by alex

  I have just seen this in code var thisYear = (new Date()).getFullYear(); See it live on JSbin. This is cool, as I've always done something like that in 2 lines, i.e. create the new object instance and assigned it to a variable, then called the method on it. Is this new method fine to use everywhere? Any gotchas?

• PHP while(variable=mysql_fetch_assoc) - explanation

  - by Petr

  Hi, I have been working with C# so this is quite strange for me: while($variable=mysql_fetch_assoc) I have not been able to look up in PHP manual how it works. I guess that in each loop it advances to next element of assoc.array. But what is this generally called in PHP? I am just not used to see '=' in loop condition.
