Re: Construcor trouble Maximilien22-Mar-04 5:39 Maximilien 22-Mar-04 5:39  you can't ( ? ) use current class in initialiser list. maybe doing something like CClass(int x) { Init(x); } CClass() { Init(someDefaultValue);} ; Maximilien Lincourt Your Head A Splode - Strong Bad Re: Construcor trouble Alvaro Mendez22-Mar-04 5:50 Alvaro Mendez 22-Mar-04 5:50  C++ does not allow a constructor to call another constructor in the same class. You can only call the constructor of the base class. For your simple case you can avoid having two constructors by using the default parameters feature (which Java and C# don't have): CClass(int x = 0) : i(x) { } Regards, Alvaro Give a man a fish, he owes you one fish.

Re: Construcor trouble MyttO22-Mar-04 5:53 MyttO 22-Mar-04 5:53  In the first case when you invoke the good constructor but on another anonymous instance!!! Which is totally useless since this new instance has no relation with this In the second case, you can only use base class constructors in the initilisation list. So it's wrong. you could use for instance: *this = CClass() Hope it's been some help -MyttO Re: Construcor trouble Curi0us_George22-Mar-04 6:22 Curi0us_George 22-Mar-04 6:22  You could, but you probably shouldn't. Then you'd be constructing an extra object every single time the constructor is called. Re: Construcor trouble MyttO22-Mar-04 6:25 MyttO 22-Mar-04 6:25  It seriously depends on whether you prefer wasting time coding extra methods, or wasting processor cycles allocating and desallocating memory All is context dependant... -MyttO Re: Construcor trouble Curi0us_George22-Mar-04 6:29 Curi0us_George 22-Mar-04 6:29  Feh. :p It doesn't really take any more time to create an init method. Re: Construcor trouble MyttO22-Mar-04 21:06 MyttO 22-Mar-04 21:06  Sure, but yet it's still a code fragment in both in Class.h and Class.cpp, and then extra noise in your cade that don't bring much semantics. One of my most important guidelines in code writing is conciseness: code is easier to maintain, undestand, and even read -- since you don't have to scroll down for hundreds of pages in your favourite editor But actually, it's clearly more a style than a commandment -MyttO Re: Construcor trouble Michael Dunn22-Mar-04 6:55 Michael Dunn 22-Mar-04 6:55  real_space_monkey wrote: CClass(int x){//Second constuctor CClass();//Invoke First construcotr But this code not initialize i member!!! Why ??? Because writing CClass(); in a function body does not invoke the first constructor. CClass() means "create a temporary CClass object using the default constructor." As others have said, that code has no effect on the this object. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- "Linux is good.

I would like to write information in the file properties available in the properties tab when right-clicking a file in the explorer. Especially the title-subject-comment-revision number fields... I've scanned MSDN and CP but found nothing really useful.

J.B.22-Mar-04 4:00 J.B. 22-Mar-04 4:00  Hello guys, I am wondering if there is a way to get a handler and so to kill the messageboxes created by ::MessageBox() or AfxMessageBox() from other thread? Or I have no choice but to manually make a class to produce the very same dialogue and kill it by destroy the class. Thanks alot Re: Possible to kill MessageBox?
