class CSingleton
{
public:
static CSingleton* GetInstance();
private:
void CSingleton();
CSingleton ~CSingleton();
static CSingleton* m_pInstance;
};
In the cpp file:
CSingleton* CSingleton::m_pInstance = NULL;
.....
CSingleton* CSingleton::GetInstance()
{
if (!m_pInstance)
m_pInstance = new CSingleton;
return m_pInstance;
}

A simpler way:
--------------
// Console.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
class Single
{
public:
static Single& GetInstance()
{
static Single s;
return s;
}
void Method() const
{
cout << "Method called : this = 0x" << hex << this << endl;
}
private:
Single()
{
cout << "Instance created!" << endl;
};
};
int main(int argc, char* argv[])
{
Single::GetInstance().Method();
Single::GetInstance().Method();
Single::GetInstance().Method();
return 0;
}
--------------
This technique leverages the langauges rules: A static member is created the first time it's encountered. This way we don't need the "new" or the "if" or to remember to "delete" it.

Yes, that another way of doing it. Both techniques have their pro and cons. I remember having read an article that was discussing several singleton implementations but I don't remember the link.
Yours is great when it has to be used 'alone' because as you said you don't have to worry about releasing the instance.
But in some cases, this can lead to problems: if you have a singleton that is member of another singleton, then you get into trouble because you have no control over the timings of the destruction of the instances. In such case, you need to control yourself the scope of the instances.

Geez ! It's the second time in one hour that you post your message. It's a forum here, not a chat. If you didn't get any answers, maybe it's because you don't give enough information.
As far as I know, a computer cannot send SMS. So, asking how to send SMS through VC++ is nonsense. First find something that can send SMS (for, that, I have no clue) and if you are stuck about how to communicate with this device (or whathever it is), then come back asking specific questions.
It's a programming forum here, not a phone company service  .

If you are looking for a function like ::SendShortTextMessage(LPSTR msg), I'm really sorry.

Open the resource editor and expand the node for version .
double click the VS_VERSION_INFO child and their you have the window to set up all the entries.
Somethings seem HARD to do, until we know how to do them.
