Hi Guys,

i want to list and check the status of each contact of my Office Communicator

for this i have done till
1)i can see number of contact from get_count method
2)GetContact method is also successfully executed.

and done know how to move further..

any help is appriciated..

C++

CoInitialize(NULL);
	HRESULT  hr = CoCreateInstance(CLSID_Messenger,NULL,CLSCTX_LOCAL_SERVER,
	IID_IMessenger, (LPVOID *)&m_pIMessenger);

	BSTR myName;
	MISTATUS sMyStatus;

 	//hr = m_pIMessenger->get_MyFriendlyName(&myName);
	hr=m_pIMessenger->get_MySigninName(&myName);
	hr = m_pIMessenger->get_MyStatus(&sMyStatus);

	BSTR serviceId;
	m_pIMessenger->get_MyServiceId(&serviceId);

	IDispatch *pContacts;
	IMessengerContacts *pCon;
	  BSTR bstrServiceId;

	      hr = m_pIMessenger->get_MyServiceId(&bstrServiceId);
		
	  if (FAILED(hr))
		 return NULL;

	

	  hr = m_pIMessenger->GetContact(myName, bstrServiceId, 
                                     (IDispatch**)&pCon);
	  </blockquote>

I don't see the items you refer to in your code extract.

Bow here i can see the count..now i want to iterate through each contact ..i am not getting right method to do the same.

Use the Item[^] method.

Thanks Rich..

added

IDispatch *ppContacts;
    hr=pCon->Item(0,&ppContacts);

after that not getting any clue how to proceed further...any help ..i am just blank...

Well I guess you need to iterate through the list from zero to the maximum value as indicated by the Count property.

i tried that as above...

C++

hr=pCon->Item(0,&ppContacts);

now ppContacts seems to be another interface with all COM predefined methods like Querry interface ,addref release etc.

You really need to spend a lot more time reading the documentation on this interface before trying to implement it.

Thank you so much Rich.. yes there is a need of going through the documentation.

Not sure why char[100]... ??? ...why not get the size first then allocate the array dynamically?

But, you can use the CString::GetBufferSetLength() (allows you to specify maximum size) method then just copy the contents of the buffer to the char[] using memcpy().

For Example i took char[100] As you mentioned i need to take the length of the string.
Thankyou Albert.

Richard MacCutchan20-Dec-11 21:37

Use strcpy() or its wide character equivalent for the copy. For further information see here[^].

C++

LPSTR WideChar2MBCS( const CString& strCS )
{
	const UINT wLen = strCS.GetLength() + 1;
	UINT aLen = WideCharToMultiByte(CP_ACP,0,strCS,wLen,NULL,0,NULL,NULL);
	LPSTR lpa = new char[aLen];
	WideCharToMultiByte(CP_ACP,0,strCS,wLen,lpa,aLen,NULL,NULL);
	return lpa;
}

maybe this will help you.

I have a dll COM , I want to convert it to UNICODE.
I readed some documentations about this but I can't get what I should do to be sure that the conversion is done correctly or Not D'Oh! | :doh:

these are some remarks i have done in my code :

- Use of CString
- char changed by _TCHAR
- char*, LPSTR (Win32 data type) changed by LPTSTR
- const char*, LPCSTR (Win32 data type) changed by LPCTSTR
- USES_CONVERSION macro
- use of std::wstring instead of std::string
- change characters set of project to UNICODE

I don't know if it is sufficient or there are others things to do
And How can I check after conversion if it is Ok or Not.

Thanks for reply.

You also need to make sure all your string literals ar changed from char to TCHAR with the _T() macro like this:

C++

const char* cp = "Ansi string";       // old style char literal
PCTSTR tcp = _T("TCHAR string"); // will generate Ansi or Unicode depending on project settings

After that, the only way to be certain you have it right is to desk check and test. There may be some free tools around to help verify it but I'm not aware of them; Google may help you.
