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.

Try putting a printf in the out and see if it gets executed.

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!

("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...
