Ron, Paul Vlad explains how to implement this calculator class some
month ago and i implemented this successfully.

Unfortunately, FoxPro calculator is buggy, it produces
numeric overflow errors, for trying to get square root of 123
or using division, fox example.

>I'm looking for a calculator control (ActiveX or VFP class) that can return a value that can be pasted in a numeric field. I'm aware of FoxPro's built in calculator, but it doesn't have an "Accept" or "Ok" button to let me know that the user actually wanted to "paste" the value. All I need is the calculator control - I can subclass it to add the "OK" or "Accept" buttons. Anyone have such a control?
