Example Code
HRESULT MyFunc([in, optional] VARIANT Param1,
[out, optional] VARIANT Param2)
I'm concerned about the client calling sunctions which have optional arguments....my client in cpp raise an error on number of parameters. Any one with time n clue

1. I think [out] and [optional] are not compatible
2. C++ client does not translate COM optional argument to C vararg. Instead, for each optional argument you want to skip you have to pass VARIANT of type VT_ERROR with a value of DISP_E_PARAMNOTFOUND
so in you case it would look like
VARIANT vOptional;
vOptional.vt = VT_ERROR;
vOptional.scode = DISP_E_PARAMNOTFOUND;
pMyObj->MyFunc(vOptional, vOptional);

Hi,
I have made a collection component, that inherits the functionallity from ICollectionOnSTLImpl ( but no fancy enumerator implemented).
My question is.. how can I use that in my MFC application ?, I'm using fancy smart pointers
<br />
MNEMOSYNELib::IXMLProjectsPtr pIProjects;<br />
<br />
Hr = pIProjects.CreateInstance(__uuidof (MNEMOSYNELib::XMLProjects));<br />
If I call something like "get_count" it fails... but how can I change to the collection interface without having to make a classic query interface, and for which Interface should I ask ?
Thanks in advance, greetings
Braulio

In my project,I add a ATL object .The wizard add a ***.rgs file to my project.I open the file ,the text like this :
HKCR
{
NoRemove AppID
{
{2C0CA281-E28B-41CA-838C-C7D1BEA311D2} = s 'NewEn'
'NewEn.EXE'
{
val AppID = s {2C0CA281-E28B-41CA-838C-C7D1BEA311D2}
}
}
}
Who can tell me what these words mean?

|
|
|
|
Can I add some information into it?
|
|
|
|

This is information that is added into the registry to "register" you COM server with Windows.
HKCR = HKEY_CLASSES_ROOT
The rest of the information is assigning an unique identifier to your COM exe server, so whe you make a CreateInstance call it knows which application to load.

I make a group of control .How can I identify them? Should I add a registry entry to registry? How can I do it?Help me.

The easiest(if not the only) way is to group them in one TypeLib

Hello,
I wanted to create a new ATL object (you know, right-click on projects classes, "New ATL-Object", the dialog where you normally can select "Simple Object" etc...), but this dialog doesn't contain any items any more! There are no icons like "Simple Object" any more!
Has anyone experienced the same problem? How do I get these items again?

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

I thinke you should reinstall your VS 6.0.Gool luck!
|
|
|
|
|
Try "regsvr32 \Microsoft Visual Studio\Common\MSDev98\Bin\IDE\ATLOBJ.DLL".
Could be helpful.

When i add notification handlers like this one here,
NOTIFY_CODE_HANDLER(NM_CLICK,OnClick)
the functions aren't called. I guess i must have done something wrong subclassing this listview but i don't know what.

LRESULT OnActivateItem(int idCtrl, LPNMHDR pnmh, BOOL& bHandled)

MessageBox("blah");
return 0;
}
};
It's the CLICK one that doesn't work...
Thnx

Ok, what you want is to reflect notifications. For this you will have to add REFLECT_NOTIFICATIONS() to the bottom of the containing window's message map:
BEGIN_MSG_MAP(thisClass)
...
REFLECT_NOTIFICATIONS()
END_MSG_MAP()
Then, change your NOTIFY_CODE_HANDLER with REFLECTED_NOTIFY_CODE_HANDLER. You may also want to add a DEFAULT_REFLECTION_HANDLER() to the end of your List's message map.
Things should work, now.

Thanks for explaining me this! However, it still doesn't work....function isn't called...

What are the template arguments for CWindowImpl?
|
|
|
|
|
class CContactlist : public CWindowImpl<ccontactlist, clistviewctrl="">
|
|
|
|
|
Shouldn't this be:
class CContactlist : public CWindowImpl<CContactList, CListViewCtrl>
?
|
|
|
|
|
Yeah that's what i have, i forgot to put it in a code tag... it's exactly what i have.
