Shouldnt this constructor catch that hbm is null in the OUT contract ?

class Bitmap

public:
 HBITMAP hbm;
 BITMAP bm;

 this()

  hbm = null;
  bm.bmWidth  = -1;
  bm.bmHeight = -1;
 }

 this( char[] name )
 out {  // here, this never gets executed it seems
  wassert( hbm !== null ,"hbm !== null in File : [images.d] Line :  (25) ");
  msgBox("HERE");
 }
 body {

  hbm = LoadImage( WA.globalInstance, c_str(name), IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE|LR_CREATEDIBSECTION );
  if ( hbm !== null )
  {
   GetObject( hbm, bm.size, &bm );
  }
  else
  {
   msgBox("image load failed");
   msgBox(OS.getLastError() );
  }
 }

It seems that the out part of the contuctor is never hit , am I missing
something ?  Im getting a message box with image load failed ... but no
wassert, and no msgbox in out contract.

My fault, a -release got slipped in there, it works as expected :).

On a side-note , ive been using D alot lately , and I've run into almost no
trouble at all , be it internal errors , weird compiler error messages ,
import troubles etc.  I think D is a perfect candidate for extreme
programming ( though I think we've all been practicing this long before they
had a name for it ) , which almost elimiates the need for a debugger.  With
the upcoming template revisions I think it will be ready for full blown use!

Can't wait for the new release!

 I think my weekend import epiphany will cover most of the
 problems I was having...


Can you summarise this for the rest of us?

It's that boring thread I started
D/20837

basically for 2 files with 2 classes do:
###############
module MA;
class A
{
	import MB;
	B b;
}
###############
module MB;
import MA;
class B : A
{

}
###############
and the forward references problem goes away.
it's obvious!
("The use of j*va cripples the mind..." ;)
if there are any S*n guys monitoring this: it's a joke)
I'm just used to put imports outside the class definition.

I'm gonna change all my programs to have the imports inside the class
definition except the modules with the super class and interfaces.

I bet I can now code the dispatcher access on DUI callbaks as I
originally intended (except that I'm gonna change that to delegates...)

This ends a 3 or 4 month long quest!... and it's obvious...
(I hope...)

That's really nice to hear, as usually most of what I get are bug reports!

 Can't wait for the new release!


I can't wait to finish it <g>.
