Text-Box to Double conversion

[indiocolifa]

I've three textboxes I want to convert to Double.

I don't know to use the IFormatProvider interface ...

				 // obtener los números desde el textbox
				 IFormatProvider* ifp;
				 Double a = A_coeff->Text->ToDouble(ifp);
				 Double b = B_coeff->Text->ToDouble(ifp);
				 Double c = C_coeff->Text->ToDouble(ifp);

The problem is in ToDouble(ifp).. that's causing an exception.

A_coeff, B_coeff and C_coeff are the textboxes.

Thanks!

Double a = Double::Parse(A_coeff->Text);
Double b = Double::Parse(B_coeff->Text);
Double c = Double::Parse(C_coeff->Text);

I'm new to C++ .NET so I don't know if this is right but it converts properly..

Jinto, it seems that a newcomer is sometimes what is necessary to get a straight answer. Of course, if you are still visiting this site, you are not so new to .net now! Thanks.

Parse is throwing an exception if the function fails. TryParse is not throwing.

Hi ,

If Parse is throwing an exception, then the problem is with the conversion,

As for TryParse, it shall never throw an exception, as it returns a boolean value on succesful conversion.

I suggest you use TryParse .
