Can you access private memeber data/functions from static member function

class X
{
private:
  int MyVal
public:
static void MyStatic(X *cls)
{
  cls->MyVal=10;
}
void DoStaticStuff()
{
  X::MyStatic(this);
}
};
int main()
{
  X MyX
  MyX.DoStaticStuff();
}

Actually, I wasn't reading quite carefully enough, the way in which you are doing it is a little unusall, but legal.  When I said it was done often I was thinking you were accessing a private _static_ data member.  That is more common.

Out of curiousity, why did you code it that way?  i.e why make MyStatic() static.  That would be a good funciton to have as non-staitc.  Was it just for an example?

Thanks. Short and to the point (I guess easy questions merits easy answers).

The reason for the odd construction is deliberate. MyStatic is used in a call to CreateThread(), passing 'this' as the startup argument. (of course, in real life it would look sligthly different).
