how to put multiline comment to function header

hi,
i want to create a function with the FileCodeModel and put a comment for the function. the problem is that i want to make a comment like this:

<br />
/***********************<br />
*<br />
* Comment example<br />
*<br />
************************/<br />

but i dont know how to make it, i know only to make this type of comment :

<br />
// Comment example<br />

with this code -

CComPtr<EnvDTE::CodeFunction> l_pCodeFunction;<br />
CComPtr<EnvDTE::ProjectItems> l_pProjectItems;<br />
CComPtr<EnvDTE::ProjectItem> l_pProjectItem;<br />
CComPtr<EnvDTE::FileCodeModel> l_pFileCodeModel;<br />
<br />
pActiveDoc->get_ProjectItem(&l_pProjectItem);  <br />
l_pProjectItem->get_FileCodeModel(&l_pFileCodeModel);<br />
l_pFileCodeModel->AddFunction(L"DoSomething",EnvDTE::vsCMFunctionFunction,CComVariant(L"void"),CComVariant(1),EnvDTE::vsCMAccessPublic,&l_pCodeFunction);<br />
l_pCodeFunction.put_Comment(???) // TODO<br />

does someone knows how to make multiline comment?

Hi!

I have some compiling problems with my shell projects. I can not compile them since I keep getting the error that there is no precompiled .pch-file...

What am I doing wrong? I am a bloody beginner.. (this is my first project)

pls help me. I know it's a very stupid question, but I can seem to solve the problem.

Thx in advance

Either

add a precompiled header - add stdafx.h and stdafx.cpp to your project and compile stdafx.cpp with the option /Ycstdafx.h

OR

remove mention of the option /Yu (you'll possibly see it as /Yustdafx.h) from the compilation options of your project

HTH!!!

What overloaded member function called in if(iterator)

Hi,
Can anyone tell me which overloaded function is called, below in Line 2:
vector<int>::iterator it = nArray.begin(); // Line 1
if(it) //What overloaded function called here // Line 2
..................

As I know in this case overloaded (operator void *) function is called,
But I d'nt find any such overloaded function in STL iterator class.

Regards

As you point out, there's no official procedure in the STL specification to test an iterator in such a way. What's happening is that, for vector alone, and for your particular compiler, vector::iterator happens to be an actual pointer, so the expression makes sense --it tests whether the pointer is non-null, which makes little sense in the given context. This is non-portable and you are not guaranteed that the test yield any significative result. Most likely what's intended is the following:

if(it!=nArray.end()){
  ...
}

Hope this helps,

Hi Joaquín,
Thanks for suggestion
I still want to know which overloaded function of iterator is called
when we write:

if(iterator)

There is no general answer to your question.

Actually, you should not even ask the question because the "if (iterator)" should not generally compile. However, in your case, the magic of typedef's probably makes it valid and equivalent to "if (pointer)".

Also, the "suggestion" to do "if ( iterator == container.end() )" is NOT a suggestion: it is the only valid way to check for iterator validity.

my 2 cents...

Set a breakpoint on that if statement, and step into the line (F11) and you'll see.

using cout in template argument...

Malcolm Smart7-Feb-05 22:23

Hi
I want to be able to dump a map out to any stream, ie cout, fstream, or stream into another class (the other class has the << overloaded) but I can't even pass cout into the template. I've cut the code back to the following....

typedef map<string , string> myMAP;

class MyClass
{
private:
	myMAP somedata;
public:
	void LoadSomeData(T &t) {//load map here};
	template <typename T>
	void DumpSomeData(T &t);
};


template <typename T>
void MyClass::DumpSomeData(T &t)
{
	myMAP::const_iterator iter(somedata.begin());

	while (iter != somedata.end())
		{
		t << "#" << iter->first << "#" << iter->second << endl;
		iter++;
		}
}

and to call it I use...

MyClass LoadAndDump;
LoadAndDump.LoadSomeData();
LoadAndDump.DumpSomeData(cout); <-- compiler errors....
//also tried
//LoadAndDump.DumpSomeData<std::basic_ostream<char,struct std::char_traits<char> > >(&cout);

It won't compile and gives

error C2893: Failed to specialize function template 'void __thiscall MyClass::DumpSomeData(T &)'<br />
        With the following template arguments:<br />
        'class std::basic_ostream<char,struct std::char_traits<char> > *'

Any help much appreciated.

Regards

Angel

Are you using MSVC++ 6.0? This compiler is notoriously ill-behaved when dealing with member function templates. Though I'm not 100% sure, sometimes moving the definition to the declaration of the class helps:

class MyClass{
...
  template <typename T<
  void DumpSomeData(T &t)
  {
    // put the definition here
  }
...
};

Yes - using MSVC++ 6.0, and yes, moving the definition to the declaration works a treat.

Control's window not ready even in FinalConstruct()

greekgoddj7-Feb-05 5:21

Hello,

Things only seem to get stranger everyday.

If I am not mistaken, in an ATL ActiveX Control, the aim of FinalConstruct is that by the time the program reaches there, the object has alreay been created.

however that does not seem to be the case.

In FinalConstructor() m_hWnd in the next statement is NULL.
CWnd* parent = CWnd::FromHandle(this->m_hWnd);

How can the control's window not exist after the constructor has been completed?

Placing the same statment in the OnDraw function works, but not in FinalConstruct()?

Am I missing something? Is there some sort of FinalNoReallyThisOneIsTheFinalConstruct() ? WTF | :WTF:

Thanks

Because the C++ object and the window have different lifetimes. The C++ object is created before the window is. FinalConstruct() is, as the name implies, part of the construction process, so only the C++ exists when it is called.

Try trapping the WM_CREATE message. Or WM_INITDIALOG if you're using a dialog based window.

Yup....the solution is...

LRESULT CKnob::OnShowWindow(UINT /*uMsg*/, WPARAM wParam, LPARAM /*lParam*/, BOOL& /*bHandled*/)

Thats where the window is already created and ready. Needed to overide that and add my code inside there.

Thanks! Poke tongue | ;-P

In virtula method FinalConstruct() is control created in sense of com object. Creation of control (window) is performed in method OnCreate(...) (this is message handler of message WM_CREATE like in common window).

I have included the path to the WTL files in the properties section of the solution.

Anybody with an answer?
