I write a program to count the number of objects. But when I compile it, I met with link errors. How can I resolve it?
Head files:
template <class beingcounted="">
class Counted
{
public:
class TooManyObjects{};
static int getObjectNum()
{
return m_ObjectNum;
};
protected:
Counted();
Counted(const Counted& count);
~Counted() { --m_ObjectNum; };
private:
static int m_ObjectNum;
static const size_t m_MaxObjectNum;
void init();
};
int Counted<class beingcounted="">::m_ObjectNum = 0;
const size_t Counted<class beingcounted="">::m_MaxObjectNum = 5;
class Printer: private Counted<printer>
{
public:
static Printer* makePrinter();
static Printer* makePrinter(const Printer& rhs);
~Printer();
void reset();
void performSelfTest();
using Counted<printer>::getObjectNum;
using Counted<printer>::TooManyObjects;
private:
Printer();
Printer(const Printer& rhs);
};
in definition file:
template <class beingcounted=""> Counted<beingcounted>::Counted()
{
init();
}
template <class beingcounted=""> Counted<beingcounted>::Counted(const Counted& count)
{
init();
}
template <class beingcounted=""> Counted<beingcounted>::init()
{
if(m_ObjectNum > m_MaxObjectNum)
{
throw TooManyObjects();
}
++m_ObjectNum;
}
Printer::Printer(){}
Printer::Printer(const Printer &rhs) {}
Printer::~Printer() {}
Printer* Printer::makePrinter()
{
return new Printer();
}
Printer* Printer::makePrinter(const Printer& rhs)
{
return new Printer(rhs);
}
error LNK2001 private static int Counted<class printer="">::m_ObjectNum"XXX" is unresloved
error LNK2019 protected: _thiscall Counted<class printer="">::Counted<class printer="">(void)
"private _thiscall Printer::Printer(void)"
why? Does the static memeber of a class can only be initialized by its base class. How about its derived class?
Many thanks

In the definition file, you need to declare it also. ( One time in the .h and one time in the .cpp)
I hope it resolves this error

There is an API RegDeleteKeyValue, I am using that in my program, but I am getting the error "Error 1 error C3861: 'RegDeleteKeyValue': identifier not found", though I have included the required header files.
Documentation of that API: http://msdn2.microsoft.com/en-us/library/ms724848.aspx[^]
Does anyone know about that problem?

The remarks section for the MFC version of this function says:
This member function implements the behavior of the Win32 macro, ListView_SetSelectionMark, as described in the Platform SDK.
And the remarks section for the Platform SDK version of this function says:
The selection mark is the item index from which a multiple selection starts. This macro does not affect the selection state of the item.
Here, you are trying not only to set the selection mark, but to change the selection state of the item. So, making a consequent call to SetItemState() works for me.
m_myList1.InsertItem(0,"adad");
m_myList1.InsertItem(1,"dase");
m_myList1.InsertItem(2,"rweq");
m_myList1.SetSelectionMark(1);
m_myList1.SetItemState(1,LVIS_SELECTED|LVIS_FOCUSED,LVIS_SELECTED|LVIS_FOCUSED);

Hi everybody,
if my application accepts an eMail which is send via Drag'n'Drop, i need to
extract the data stored into the clipboard to determine the text of the mail.
If i drag an eMail on the Desktop, does Windows the same like my application?
So if a mail can be saved on the desktop via Drag'n'Drop to an .eml file,
all informations about this mail are into the clipboard?
Or does the eMail-Client this work? Knowing where the file has been dropped and
creates the .eml File by knowing his own data?
Big thanks

I am using CryptUnProtectData function to decrypt Wireless Access Password
from a Wireless Connection Profile.
Even though I am able to decrypt the password on a Windows Vista PC, I am
not able to do this on a Windows XP Machine. I am calling CryptUnProtectData
inside a windows service application.
Is it possible to decrypt the wireless connection password using
CryptUnProtectData on a Windows XP PC ?

What happens when you try it on your Windows XP machine?
