[GNUStep installers] gnustep-system-0.24.2-setup.exe gnustep-core-0.25.0-setup.exe gnustep-devel-1.1.1-setup.exe gnustep-cairo-0.22.1-setup.exe I installed them to windows 7. But, it is not able to use Objective-C 2.0 syntax. Example, @property, @synthesize, assign, and so on. And, I want to use CFSocket, but CoreFoundation was not su...
let sub (a:float[]) (b:float[])= [| for i = 0 to Array.length a - 1 do yield a.[i]-b.[i] |] let fx t = [0..t] let x=sub (fx t) (fx t) Above compiles OK. But the same causes an error when I replace the function call with a method invocation: type type_f = delegate of float -> float[] let mutable f =new type_f(fun t->[|0..t|]) l...
Hi all, Can I somehow get a reference to the instance I am creating using object initialiser var x = new TestClass { Id = 1, SomeProperty = SomeMethod(this) } "this" should point to the new TestClass instance I'm creating. But it obviously refers the the instance of the class i...
print the string is using [NSString stringWithFormat:@"%@", @"String"]; if I want to print integer, I just use %i, what should I do to print a short type? thank you. ...
Hi, Can you briefly list the differences between <%= %>, <%# %> and <%$ %> by giving a simple example maybe that requires only one of those expressions to be used? Thanks ...
Why does the below code not compile (snippet) ? public enum ApplicationType : int { CONSOLE = 1, WINDOWS_FORMS = 2, ASP_NET = 3, WINDOWS_SERVICE = 4, MUTE = 5 } //#if( false) //#if (DEBUG && !VC_V7) #if( m_iApplicationType != ApplicationType.ASP_NET ) public class HttpContext { public...
Here is the code: -(void)myOwnMethod{ NSString *myString; myString = [[NSString alloc]init]; /* Some logic about the String */ [myString release]; //Do I need to release the myString Object? } As you can see, the myString object is only used in the method, do I need to release it? or it will auto relea...
Visual studio 2008 isn't catching syntax errors. for example: Tpc_feed(void); compiles fine. this: Tpc_feed(void);;;;;;; compiles fine, but this Tpc_feed(void) catches an error. Are the extra semi-colons not syntax errors? I'm on Windows 7 32 bit and VS C++ 2008 ...
I am using objective c, and I got some variables like this: 1100 920 845 1439 But I want to change it to : 11:00 09:20 08:45 14:39 The problem is how can I fill the zero when I got three number only? I know the logic can be simple to do it I detect the string length, but is there any way to do it more effectually? Thank you. ...
What is the best (most compact) way to hand this situation: One or more arguments to a method call depends on some condition, while the rest of the arguments are identical? For example-- you want to DeathRay mynewWpn = new DeathRay(particle.proton, chassisColor.BLACK, oem.ACME) if enemy_composition == nature.ANTIMATTER but Death...
Hi All, I know how to initialize a static member, but I'm wondering, what is the rationale behind the syntax for this? I'd like to be able to just put the value in the class, a la: class A { static const int i = 3; }; I realise this could mean more rebuilding if I change the value since it's a change in the header - but in some cas...
Hey, I have a client who needs a website urgently, but I have no access to information such as the control panel. PHP Version is 4.4 Which is a pain as I'm used to 5. The first problem is I keep getting: Parse error: parse error, unexpected T_OBJECT_OPERATOR, expecting ')' in D:\hshome\*******\********\includes\functions.php on line ...
Is there a way to do this : SubSonic.Where filter = new SubSonic.Where(); filter.ColumnName = Region.Columns.Region; filter.Comparison = SubSonic.Comparison.IsNot; filter.ParameterValue = null; SubSonic.Aggregate orderBy = new SubSonic.Aggregate(Region.Columns.RegionName, SubSonic.AggregateFunction.GroupBy); RegionCollection regions =...
I've been using The New Boston tutorial (http://www.youtube.com/watch?v=x9M3R6igH2E) on how to program with pygame and I keep getting an "invalid syntax" error on the print self.diff command. Only the self is highlighted. Here is the code (i've bolded the problem): class vector(object): def __init__(self, list1, list2): self.diff=(...
what does & sign mean when used in objective c for example? int i = 1; NSData *data = [NSData dataWithBytes:&i length:sizeof(i)]; ...
I may have this wrong, but I've seen the way of creating an overloaded method that calls itself in the definition. It's something like: public void myFunction(int a, int b) { //Some code here } public void myFunction(int a) : this (a, 10) { } This is not the correct syntax, I know, but I can't find the correct syntax anywhere for...
I see foo() { if [[ $# -lt 1 ]]; then return 0 fi ... } What exactly is it comparing by using $# as it does there? ...
I have a SQL statement, in ColdFusion, and I want to limit the size of one field. Neither of the following appear to work (they don't give errors, they just don't limit the field). INSERT INTO ListItems VALUES ('#qGetListID.ID#', <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#listItems[i].itemID#" />, <cfqueryparam cfsqlt...
In my Jekyll blog I use the include tag to put the contents of a file into the document. However if I attempt to do this with a HAML based document the indentation of the included text is wrong. :preserve does not work because it requires indentation. Is there a way to specify a block of text without depending on indentation? %html %b...
I understand the difference in behavior. Date() returns a String representing the current date, and new Date() returns an instance of the Date object whose methods I can call. But I don't know why. JavaScript is prototyped, so Date is a function and an object which has member functions (methods) which are also objects. But I haven't wri...
