Hello everyone

First and foremost, THANKS TO ALL OF YOU WHO PROVIDED AN ANSWER/OPINION. I'm learning a lot.

Now, as an academic curiosity, I think that if I make a vector container available outside the function (by making it global), then it should be equivalent to using:

double* pt_tovector = new double[2];

without deallocating the memory at the end of the function. Memory will remain caught until the program exits which is something I need to avoid since my code is big. In which case, since for this particular example I only need to retrieve two values, I rather make the whole function void with the two values of interest private and then include a couple of tiny accessor functions, one for each value... is this solution too ugly a programming style??? Poke tongue | ;-P

Many thanks again!!!

Yes, you should return a pointer to the first element of the vector, but your code doesn't do that! You must actually write pt_tovector = &A_vector[0] in your program to return a pointer to the first element of the STL vector A_vector. Additionally, the vector can't be local to the function.

How do I save/load STL data (map & vector)

Can someone show me how to send (save/Write) and receive (load/Read) data contained in a map and/or vector. class CData{ public: string one, two, three; CData() {}; ~CData() {} };

the map is declared as: map<string CData> DATA; How do I read/write it's data to a file ("MyMapFile.dat") ???

vector<CData> vecDATA; how do I read/write it's data to a file("MyVecDATA.dat") ???

I'm new to the STL and would need explicit examples that are known to work properly PLEASE.

C++ is my favorite programming language

You cannot automatically serialize STL objects to files. You must write your own file format. If you use only MFC then you can use CArray and CMap as containers and serialize with CArchive.

Is it possible to get the title that is enclosed in the html as <title>My webpage</title>?

I have found that IWebBrowser2 have the GetProperty method, what are the properties of the page that we can get?

IWebBrowser2->GetDocument() will return the the docuement interface of the Loaded page.

wait a min i demonstrate that by code

/*testing*/<br />
	IHTMLElementCollection *pColl=NULL;<br />
	IHTMLElement           *pEle=NULL;<br />
<br />
	m_HtmDom->get_all(&pColl);<br />
MessageBox("yeah");<br />
	<br />
	CComVariant varTitle("title");<br />
	CComVariant varIndex(0);<br />
	IDispatch *pDisp;<br />
<br />
	pColl->item(varTitle,varIndex,&pDisp);<br />
	//pColl->Release();<br />
	//pColl=NULL;<br />
	MessageBox("yeah1");<br />
<br />
	if(pDisp)<br />
	pDisp->QueryInterface(IID_IHTMLElement,(LPVOID*)&pEle);<br />
<br />
	MessageBox("yeah3");<br />
	if(pEle)<br />
	{<br />
		BSTR p;<br />
		pEle->get_innerText(&p);<br />
		MessageBoxW(NULL,p,L"",NULL);<br />
	}

Templates with Variable argument List

The short answer is no. The long answer is no, but you can fake this feature. For instance, the following creates the illusion of a class template allowing for an arbitrary number of type parameters up to 10:

struct void_arg{};
template <
  typename T0=void_arg,
  typename T1=void_arg,
  typename T2=void_arg,
  typename T3=void_arg,
  typename T4=void_arg,
  typename T5=void_arg,
  typename T6=void_arg,
  typename T7=void_arg,
  typename T8=void_arg,
  typename T9=void_arg
>
class my_template
{
  ...
};
 
...
 
//user code

typedef my_template<int,char,double> foo;

Note that void_arg is used as a marker meaning "no parameter specified". Now, the real problem is how to handle the variable number of parameters to do something useful: this will lead you to the realm of template metaprogramming (google for that.) Two libraries in Boost[^] named Boost.TypeTraits[^] and Boost MPL[^] are commonly used for doing template metaprogamming (beware, this is non-trivial stuff.)

If you have a specific problem where you want to take advantage of a variable number of template parameters, please post what you've got here and I can try to help a little.

Window not being Painted

I have a WTL based application. In response to a particular user action, it is to create and show a new CFrameWindowImpl<> based window that includes a splitter and two client windows. This all works fine on my development computer. It does not work when I distribute to the computer that this application is suppose to be run on.

On the other computer, the two client windows are not being painted. Both computers are running Win2000 Service Pack 3.

Any clues?

What kind of windows are going into the splitter? It sounds like those windows are failing to be created.

Sorry, I found the answer shortly after posting the message and forgot to update my message here.

I wasn't calling PreTranslateMessage() for the two windows. Once I did this it started working perfectly.

   Please do not crosspost things like this. Start by opening the file and searching for keywords, ones with consistent formatting will be easy to spot.

   Try opening the file in an editor and see what you can find. Have you even tried running strings on it?

   Peace!

I don't know about ATLSoap but it presumably resides in a namespace. Try to do explicit namespace qualificaton. Something like:

ATLSoap::CSemaphore semaphore;

I just used the CSingleLock and CMutex contained in MFC, I needn't use the ATL::CSemaphore, but I need to use the atlsoap.h related to webservie..
maybe both MFC and ATL define the CSemaphore, so compiler can't differ from them... I can't know how to avoid it.
