Hmmmm - no can do. You'll need to pass a VARIANT that contains a SAFEARRAY of doubles. Something like:
SAFEARRAY* sa = SafeArrayCreateVector(VT_R8, 0, count);
double* pSAData;
if (SUCCEEDED(SafeArrayAccessData(sa, (void HUGEP**)&pSAData)))
{
std::copy(start, start+count, pSAData);
SafeArrayUnaccessData(sa);
VARIANT v;
V_VT(&v) = VT_ARRAY|VT_R8;
V_ARRAY(&v) = sa;
}should set the VARIANT, then you can pass a pointer to it.

Hi,
I am trying to fire an event from the worker thread and it worked fine as long as I worked with a VB client inside VB development environment. As I created an exe and ran, it was crashing and found that there is a KB article in Microsoft on that talking about marshalling the sink interface (http://support.microsoft.com/kb/q280512/ ). But, when I use that, I am getting a 0x80004002 error in the pDispatch->Invoke. Appreciate your help in sorting out this issue,
Thanks & Regards,
Satish

What have you done so far?
Have you initialized the new apartment with a call to ::CoInitialize()?
You cannot fire events from a secondary thread without marshalling since the call crosses apartment boundaries.
You could also post a message to the main thread and fire the event from there.

Hello Satishkumar,
Not sure why you are getting your error. I've tried to use ATLCPImplMT.h entirely as advised by the MSDN article in http://support.microsoft.com/kb/q280512/[^]
and faced no problem.
If you would like to have a look at my sample codes, pls email me :

Bio.

//Belows are from MSDN2003, an example about hash_set::find

hm1_AcIter--;
hm1_RcIter = hm1.find( hm1_AcIter -> first );
cout << "The element of hm1 with a key matching "
<< "that of the last element is: "
<< hm1_RcIter -> second << "." << endl;
}
Output
The element of hash_map hm1 with a key of 2 is: 20.
The hash_map hm1 doesn't have an element with a key of 4.
The element of hm1 with a key matching that of the last element is: 30
My question is: hm1_RcIter is definded as a iterator, how can it use the member function of Pair: "hm1_RcIter -> second "? what is wrong?

An iterator just has 2 pointers. First pointer points to the key value. Second pointer points to the value itself for that key. The member variable/function second is not a member of the pair class. It is a specific part of the iterator itself.
From what I can see, nothing is wrong with your code. What's the problem? Nothing.

I build my project with "Win32 Unicode Release MinSize" setting. It defines "_UNICODE", "_ATL_DLL", "_ATL_MIN_CRT". And I don't want my dll to use MFC and CRT.
now I need to format strings. I think I should prevent calling functions like "_stprintf" from using CRT. But I don't know other way to fromat strings. Can you tell me some helpful Win32 functions. Or, maybe my idea is wrong!

Hi All,
I am working on an ActiveX based project.
I am using AtlAxCreateDialog method to create a dialog whose resources have been specified in a RC file. The dialogue gets created perfectly fine but i have not been able to handle its events like OnSize, OnClose etc
It has taken me a while to solve this problem but didn't succeed. Kindly, help me.

Calling AtlAxCreateDialog directly is unusual: normally it’s called for you in the implementation of the CAxDialogImpl::Create method.

I have created a toolbar for IE and added a an edit control to it, but I couldn't add a menu control beside to the edit control. Can anybody help me, please. Thanks a lot.
love U much...

first, create a menu in your resource file.
second, put a button to the toolbar that will open the menu up with a style BTNS_WHOLEDROPDOWN
third, get a command handler handle the button's command ( WM_COMMAND message )
and lastly, write a method that creates the menu and tracks it. something like:
HMENU hM = ::LoadMenu(ATL::_AtlBaseModule.GetResourceInstance(), MAKEINTRESOURCE(ID_MENU);
HMENU hMPopUp = ::GetSubMenu(hM,0);
::TrackPopupMenu(hMPopUp,TPM_TOPALIGN,pointX,pointY,0,m_hWnd,NULL);
that's the way i did it, i think you can handle the rest with the holy MSDN

What does this have to do with ATL/WTL? You are in the wrong forum...

Can you more explain and with which language?

Hello,
