how do you multiply 2 edit boxes to equal 1 using a button? 1

[real]

i have 5 edit boxes, and 3 buttons.
1st box = first name
2nd box = last name , these are not important

3rd box = hours worked
4th box = pay rate , basic knowledge hrs x rate = total pay, using the calculate button

5th box = total pay

Im using visual c++, if anyone knows how to do this please reply, i cant get passed this. im currently lost.

real,

Use the 'Class Wizard' to set up the following:

*double variable for 'hours worked edit box', name (_nHoursWorked)
*double variable for 'pay rate', name (_nPayRate)
*CString variable for 'total pay', name (_sTotalPay)
*Message Handler for the 'Calculate' button, name ( OnCalculate)

I will assume you know how to do these things since they are fundamental aspects of Visual C++ MFC development and details are in all the tutorials.

Then this would be the code in OnCalulate:

void MyDialog::OnCalculate(){
// use DDX to copy window data into class varialbes
UpdateData();
_sTotalPay.Format("%9.2f", _nHoursWorked * _nPayRate);
// use DDX to copy variables into window controls
UpdateData(FALSE);
}

Hope this helps
