• SEL performSelector and arguments

  - by madmik3

  Hello, It seems like there should be an easy way to call a selector with some arguments when all you have is a SEL object. I can't seem to find the correct syntax. -(MyClass*) init: (SEL)sel owner:(NSObject*) parent { int i =10; [parent performSelector:sel:i ]; }

• Where can I find some good tutorials for C++

  - by Rob

  My friend has convinced me to start learning some C++, so my question is simple: where can I find some good tutorials for it? But please don't link me to the usual dry boring tutorials that only tells you the function syntax, I need more thorough explanations. I get sidetracked very easily, and I need tutorials that are more on a human level, that I'll not only learn from, but enjoy reading as well. So I'd appreciate any links that would help :)

• Pass a pointer to a proc as an argument

  - by user146780

  I want to pass a pointer to a procedure in c++. I tried passing this LRESULT(*)(HWND, UINT, WPARAM, LPARAM) prc but it didn't work. How is this done? Thanks HWND OGLFRAME::create(HWND parent, LRESULT(*)(HWND, UINT, WPARAM, LPARAM) prc) { if(framehWnd != NULL) { return framehWnd; ZeroMemory(&rwc,sizeof(rwc)); } } By "it didn't work" I mean it's a syntax error.

• jQuery validation: .each with form

  - by Kevin Brown

  If I have a form of about 40 questions, how do I apply the same rules to questions 1-20, and 21-40? For example: $("#form_survey").validate({ rules: { a_ +i: {max:12, maxlength:2}, }, messages: { a_ +i:{ max: "That's too much!" } } Where the "+i" is the ideal increment of +1... Should be easy, I'm just stuck on syntax...

  var currentDate=new Date(); currentDate.setFullYear(2011); alert(currentDate); == this works, it sets the year to 2011 as expected. alert((new Date()).setFullYear(2011)); == this one doesn't work. Any idea why? Am I misunderstanding the syntax?

• Creating Tests at Runtime

  - by James Thigpen

  Are there any .NET testing frameworks which allow dynamic creation of tests without having to deal with a hokey Attribute syntax? Something like: foreach (var t in tests) { TestFx.Run(t.Name, t.TestDelegate); } But with the test reporting as you would expect... I could do something like this with RowTests et al, but that seems hokey.

• Why don't web browsers have built in validators?

  - by August Karlstrom

  As far as I know there is no web browser with built in validators for HTML, CSS and JavaScript. Developing web pages without validation is like using a compiler that doesn't do syntax analysis. Even Firefox with its excellent plugins aimed at developers like Firebug lacks plugins for CSS and JavaScript validation. Wouldn't it be useful to have these plugins? Am I missing something?

• Flexible array member in C-structure

  - by Arpan

  Quoting from the C-std section 6.7.2.1, struct s { int n; double d[]; }; This is a valid structure declaration. I am looking for some practical use of this kind of syntax. To be precise, how is this construct any more or less powerful than keeping a double* as the 2nd element? Or is this another case of 'you-can-do-it-in-multiple-ways'? Arpan

• Concatenate a table name from a variable in a FROM clause

  - by idieeasy

  I'm trying to use a dynamically generated fully-qualified table name in sql server 2008. For example, this does not work: select max([id]) from @dbName+N'.[T1]' This will give an error like: Msg 102, Level 15, State 1, Line 73 Incorrect syntax near '+'. I know that something like this works: declare @qualifiedTable varchar(200) = @dbName+N'.[T1]' select max([id]) from @qualifiedTable But I have to do this LOTS of times so I would really like to do it in line. Is it possible?

• Fixing Combinatorica redefinition of Element

  - by Yaroslav Bulatov

  My code relies on version of Element which works like MemberQ, but when I load Combinatorica, Element gets redefined to work like Part. What is the easiest way to fix this conflict? Specifically, what is the syntax to remove Combinatorica's definition from DownValues? Here's what I get for DownValues[Element] {HoldPattern[ Combinatorica`Private`a_List \[Element] \ {Combinatorica`Private`index___}] :> Combinatorica`Private`a[[Combinatorica`Private`index]], HoldPattern[Private`x_ \[Element] Private`list_List] :> MemberQ[Private`list, Private`x]}

• XCode: Function argument indentation

  - by user343317

  I was unable to find any solution of my specific issue. I'm using Xcode 3.2. I'd like to indent the next line of function argument just one step in from the previous line: somevariable = pow( a, b); However, Xcode's syntax-aware indenting insists on converting the above into: somevariable = pow( a, b); Where the arguments are aligned with opening parenthesis of the function. How can I make indenting be configured to match my preference?

• Can I update an Android provider.Settings.System value?

  - by Mr_Ed

  I can read settings like this, for example: final String mytest = System.getString(this.getContentResolver(), System.AIRPLANE_MODE_ON); ...but can't seem to write to settings using putString, no matter what I've tried. Maybe it is the scope of this.getContentResolver()??? I'm a newbie, so who knows, maybe it can't be done, or it's just syntax? Currently the code is in the onCreate of an Activity class. Any insight is much appreciated.
