Is this right? I've never seen a dialog's method bring up another instance of itself.

Why do you not have two CEdit member variables in manual, one for each of the edit controls?

I copied exactly what the MFC App wizard did for the AboutBox that it provides.

void CMyDialog::OnManual()
{
    CAboutDlg about;
    about.DoModal();
}

Yes, one for each edit control... Actually, I changed the "Variable Type" to CString and the "Category" to Value (This was all done when you right click on the edit box and click on "Add Variable".

Did I do something wrong?

There was an error message about the power function when I compiled the code. It is: error c2668: 'pow' :ambiguous call to overloaded function.

If you couldn't figure out the problem, why don't you write your own pow() function? It's simple...

double pow(
   double x,
   double y 
);
double pow(
   double x,
   int y
);  // C++ only
double pow(
   int x,
   int y
);  // C++ only
float pow(
   float x,
   float y 
);  // C++ only
float pow(
   float x,
   int y
);  // C++ only
long double pow(
   long double x,
   long double y
);  // C++ only
long double pow(
   long double x,
   int y
);  // C++ only
float powf(
   float x,
   float y 
);

double base = 3.0;
int power = 5;
int result = pow(base, (double)power);
