Retreiving Data from a dialog box

[aaadetos]

How would one retreive data input from the keyboard into a dialog box, which the compiler would process at run-time? I thought that making an instance of the class object which contains the data would be enough; but this doesn't cut it. See the following code:

void unbound(double *unbd, int nSize)
{
	enum{nSize = 100};
	double A[nSize],B[nSize],k0[nSize],k1[nSize],s[nSize],expi[nSize],a[nSize],b[nSize];
	
	void bessk0(double *x,double *k0,int nSize);
	void bessk1(double *x,double *k1, int nSize);
	void ei(double *x, double *expi, int nSize);
	
	double x=0;
	
	s[0] = 1;
	a[0] = x*sqrt(s[0]);
	b[0] = 2*sqrt(s[0]);

	bessk0(a,k0,nSize);
	bessk1(a,k1,nSize);
	ei(b,expi,nSize);

	A[0] = k0[0]/(x*sqrt(s[0])*k1[0]);
	B[0] = (1-exp(-2*sqrt(s[0])))/(2*sqrt(s[0]));
	
	unbd[0]=0.5*(A[0]-B[0]-expi[0]);

	//trial: K0(x) --> x = rw*sqrt(s), as per A-32
	for (int t=1;t<nSize;t++)
	{
		CKuchukDlg MyClass;	
		x = 2;//MyClass.m_dWellRad; ****

		s[t] = 2*t*PI;
		a[t] = x*sqrt(s[t]);
		b[t] = 2*sqrt(s[t]);

		bessk0(a,k0,nSize);
		bessk1(a,k1,nSize);
		ei(b,expi,nSize);

		A[t] = k0[t]/(x*sqrt(s[t])*k1[t]);
		B[t] = (1-exp(-2*sqrt(s[t])))/(2*sqrt(s[t]));
	
		unbd[t]=0.5*(A[t]-B[t]-expi[t]);
	}
}

When line **** read

x=MyClass.m_dWellRad;

the compiler didn't process the variable m_dWellRad at run-time, but simply used x = 0(initialization). When I used x=2, it used the latter variable.

How then can I make the compiler use the value input from keyboard into my dialog box at run-time?

I am now aware that

WM_GETTEXT

for use in retreiving text from an edit box, could do the trick. Where should this syntax be used in the above code?
