Re: [GD-Windows] TreeView label editing

[Andrew G. <ag...@cl...>]

What do you return from TVN_BEGINLABELEDIT?

Is your TreeView part of a dialog form, or created dynamically on another
Window?

Subject: [GD-Windows] TreeView label editing

Ok, I have another treeview question, about label editing. So I'm trying to
let the user change the label of a treeview item by double-clicking on it.
My problem is that no edit box ever shows up, even though I receive the
expected messages.

So it's like this:

- the treeview is created with TVS_EDITLABELS
- when user double-click on an item I call TreeView_EditLabel
- then I correctly receive the TVN_BEGINLABELEDIT and TVN_ENDLABELEDIT. In
the first one I can catch the edit control handle using
TreeView_GetEditControl, which returns a valid handle.

Yet no edition ever happens. I receive the TVN_ENDLABELEDIT notification
immediately after the TVN_BEGINLABELEDIT one, and the text in the associated
structure is null.

What did I miss? I browsed the net in vain. I can't find a single example
clearly showing me how to do that. The MSDN didn't help much either.

Thanks,
- Pierre

[GD-Windows] Game For Windows certification process ?

[Lionel F. <li...@mi...>]

Hello guys,

Does anyone know how to get the Game For Windows certification ? (I don't 
speak about the technical part, well documented in the MSDN) :

- Who is the good person at Microsoft to contact for this ?
- How does the certification process work at Microsoft ?
- How long does this certification process take ?


Thank you a lot for your help,
Lionel

Well I sure handle other events, but the focus seems fine. I'll try to
create a small repro case if nobody gets a better idea.

i mean, are you, for instance, focussing a control under some circumstances?
or doing something else which would cause another control to receive focus?
(and therefore making it impossible for the edit label to keep focus somehow?)

No I can't edit it. I don't see the edit box. Nothing seems to happen.

Hehehe, ok.
Can you edit the label? or does it dissappear before you can edit it?

Re: [GD-Windows] Crash when overriding tree view wndproc

[Roman K. <Rom...@Pi...>]

Pierre,

i think you're supposed to use the CallWindowProc API instead of calling the 
superclass proc yourself.

static LRESULT CALLBACK MyTreeViewWndProc(HWND hwnd, UINT uMessage, WPARAM
wParam, LPARAM lParam)
{
    return ::CallWindowProc( OldWndProc, hwnd, uMessage, wParam, lParam);
}

[GD-Windows] Crash when overriding tree view wndproc

[Pierre T. <pte...@ag...>]

Hi,

I'm trying to override the treeview wndproc to catch some messages. For
other controls it worked fine, but with this one it crashes as soon as I
call the old wndproc. So it looks like this:

mHWnd = IceCore::CreateWindowEx(
    WS_EX_CLIENTEDGE,
    WC_TREEVIEW,
    "",
    dwStyle,
    desc.mX, desc.mY,
    desc.mWidth, desc.mHeight,
    hwndParent,
    (HMENU)desc.mID,
    (HINSTANCE)GetModuleHandle(null),
    null
    );


And then to override the wndproc:

typedef LRESULT (CALLBACK * WndProc_t)(HWND hwnd, UINT uMessage, WPARAM
wParam, LPARAM lParam);

static WndProc_t OldWndProc = 0;

OldWndProc = (WndProc_t) SetWindowLong(mHWnd, GWL_WNDPROC,
(LONG)MyTreeViewWndProc);


The new wndproc is simply calling the old one at the moment:

static LRESULT CALLBACK MyTreeViewWndProc(HWND hwnd, UINT uMessage, WPARAM
wParam, LPARAM lParam)
{
    return (OldWndProc)(hwnd, uMessage, wParam, lParam);
}

==> this crashes inside the old wndproc somewhere. However this same
procedure worked fine for other controls (list boxes, edit boxes....) so I'm
not sure what's going on.

Is there something special about the treeview's wndproc?

Thanks,
- Pierre

Re: [GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Jon W. <hp...@mi...>]

That is correct: DirectX Standard Annotations and Semantics.

Which, of course, seems to be way too under-specified to be truly 
useful, but as I need *some* kind of binding, I might as well make it 
that, and augment it with my own.

Cheers,

What is SAS?

And it's likely that there's some edge cases you're hitting if you hit mult=

[GD-Windows] Array member pointer problem: Visual Studio or me?

[Jon W. <hp...@mi...>]

I'm having a problem where pointer to member array returns the first 
array element as a pointer to array type. There are no skanky casts 
involved in the code, so I believe this is a bug in Visual Studio 2003. 
Does anyone here agree or disagree?



template<typename Container, typename FieldType, size_t Count, FieldType 
(Container::*Field)[Count]>
class ArrayRef {
  public:
    FieldType const *Access(Container *c) { return c->*Field; }
};

class TemplateTest {
  float foo[10];
public:
  TemplateTest() {
    foo[0] = 1.0f;
    ArrayRef<TemplateTest, float, 10, &TemplateTest::foo> ar;
    float const *p = ar.Access(this);
    assert(p == foo); // p is 0x3f800000 here in msvc 2003
  }
};

TemplateTest testIt;



Cheers,

          / h+

Re: [GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Mat N. (BUNGIE) <Mat...@mi...>]

Let me guess... you had something like this:

inline void f()
{
        class foo { public: static void blah() { printf("blah"); } };
        foo::blah();
}

And then use f() all over the place? There's some standardese about the lin=
kage type of function local class static functions. I don't know what it is=
, but it manifests as multiple COMDATs that can't be combined if you use th=
e inline function in multiple places.

Hmm. Well, the error in question here is that the compiler seems to emit
two instantiations of the same template, in the same object file,
without marking them as merge-able. Thus, the linker claims (rightly)
that the .obj file is bad.

I can try to chop it down and feed it to GCC 4, but given that the
syntax is, I think, correct, I don't have high hopes. I think this is a
MSVC specific problem. Anyway, I'll report back.

Cheers,

Re: [GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Matt J <mjo...@gm...>]

I was saying if the construct was confusing the compiler maybe try a
different approach. Template code often has problems with
disambiguation or it has problems with discerning between valid types
and unnamed types. IIRC I've seen stuff compile before that did not
link properly.

[Jon W. <hp...@mi...>]

Hmm. Well, the error in question here is that the compiler seems to emit 
two instantiations of the same template, in the same object file, 
without marking them as merge-able. Thus, the linker claims (rightly) 
that the .obj file is bad.

I can try to chop it down and feed it to GCC 4, but given that the 
syntax is, I think, correct, I don't have high hopes. I think this is a 
MSVC specific problem. Anyway, I'll report back.

Re: [GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Matt J <mjo...@gm...>]

I'm curious where Field is defined, and if the compiler can understand
it is a type.

Im thinking something like this might work... but my templates are rusty

template<class T>
{
 typedef typename T* FieldPtr

} Container;

And a pointer being passed as:

Container<pit::FloatTriple>(core_->ambientlight_[l])

The other template being

template<class Field, class C = Container<Field> >

class FieldAccessor
{
  typedef C::FieldPtr TypePtr;

  FieldAccessor(TypePtr &t) :MyTypePtr(t) {}

// accessor returns &MyTypePtr

  TypePtr &MyTypePtr;

}

Anyway, good luck :p

Re: [GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Kent Q. <ken...@co...>]

Well, my template-fu is a bit underused on my current project, so I 
can't look at this and give you a solution.

But try this: chop this code down into the smallest compileable file you 
can, and then feed it to GCC 4 and maybe the Comeau computing compiler 
test page:
    http://www.comeaucomputing.com/tryitout/

I've found in the past that when I've had tricky template troubles, one 
or the other of those compilers will generate some message that will 
give me a clue. I know this is failing on the link, but if you turn on 
maximum warnings, I wouldn't be surprised to have one of these compilers 
spit out a warning or an error.

[GD-Windows] VS 2003 generating duplicate COMDAT for template instantiation?

[Jon W. <hp...@mi...>]

I'm trying to generate a SAS parser/binder using just a little bit of 
template programing, and I'm running into the following link error (I'm 
using VS 2003). I would like any help I can get in how to work around 
this problem. I got it when I was reinterpret_cast-ing from type 
Foo::*Bar[N] to Foo::*Bar[], but I worked around that by explicitly 
passing in the array size. However, here there are no skanky casts 
involved; this should "just work." (And I've tried with and without the 
inline Access() function).


Win32DX9Graphics.obj : fatal error LNK1179: invalid or corrupt file: 
duplicate COMDAT 
'?Access@?$FieldAccessor@USasAmbientLight@impl_DX9@@VFastTriple@pit@@$GA@A@A@@impl_DX9@@QAEABVFastTriple@pit@@ABUSasAmbientLight@2@@Z'

Looking at the templates FieldAccessor, here is the code:


template<typename Container, typename Type, Type Container::*Field>
class FieldAccessor {
  public:
    typedef Container ContainerType;
    typedef Type FieldType;
    inline Type const &Access(Container const &c) { return c.*Field; }
};


Here are the two cases where FieldAccessor<> is referenced for the 
SasAmbientLight:


      //  dispatch the child
      if (!wcscmp(path, L"color")) {
        setter_ = PIT_SYSTEMNEW0("ValueSetter") ValueSetter<
            FieldAccessor<SasAmbientLight, pit::FloatTriple, 
&SasAmbientLight::color> >
            (this, core_->ambientlight_[l]);
        return true;
      }
      return false;

...

      //  dispatch the child, then return an iterator on that
      if (!wcscmp(path, L"color")) {
        setter_ = PIT_SYSTEMNEW0("OuterArraySetter") OuterArraySetter<
            FieldAccessor<SasAmbientLight, pit::FloatTriple, 
&SasAmbientLight::color> >
            (this, core_->ambientlight_, &core_->numambientlights_.get());
        return true;
      }
      return false;



pit::FloatTriple is what you'd expect, as is struct SasAmbientLight:

struct SasAmbientLight {
  pit::FloatTriple      color;
};



Btw: upgrading to 2005 isn't the preferred solution right now.
