Hi -- Short version: how can we simulate .NET/VB object-type CASTing, in Win32::OLE Perl?
Long version: We're building a bridge between a java-web-app and a .net-based-desktop app. Perl is the glue language of choice, of course :) Where we've got trouble is that the .net programmers tell us we need to "cast" object_1 to be type object_2, and we haven't see how that's done in the Win32::OLE manual pages. For example we start with a Collection, iterate through CoursesCollection->Item(ix) and from there we get a StudentsCollection->Item( foo ) which is a generic object but needs to be CAST as a 'proper' Student object instead. How do we do that in Win32::OLE? my $classes = App->Classes; my $class_ct = $classes->Count; for ( my $class_ix = 1; $class_ix <= $class_ct; $class_ix ++ ) { my $class = $classes->Item( $class_ix ); my $students = $class->Students; my $stu_ct = $students->Count; for ( my $stu_ix = 1; $stu_ix <= $stu_ct; $stu_ix ++ ) { my $stu = $students->Item( $stu_ix ); # $stu is a GENERIC object here with only basic methods # need to 'cast' it to "Student" type so we can get grades my $grades = $stu->Grades; # boom! (Name not found, meaning no such method) } } We were hoping the objects were classed somehow inside Perl, but all objects appear to be simply Win32::OLE objects, and even trying to get to the hash keys gives an error... Any pointers/flames welcome. Thanks! -- will trillich "Tis the set of the sails / And not the gales / That tells the way we go." -- Ella Wheeler Wilcox
