A simple question about global variable

[jayjay60]

In my application i use ADO method in differents method. So, in each of them when i need of smart pointer as _RecordsetPtr or _ConnectionPtr, i declare them as local variable in each of them. So, i would like to know how and where i could declare the variable so that they would declare one time only. I try to declare them in the .h file or at the top of the .cpp file and it doesn't work, so what is the correct way of doing that?

thanks in advance

if you want only one for each cpp (not for all) use

namespace
{
declarations here;//will be visible only from this cpp
}
declarations here;//are global. You can
//declare them in other places with keyword extern and
//compiller will look for this one
