Very stupid question part 2

[=?Utf-8?B?bWFyaw==?=]

Thanks Folks,

Now I need to go the other way. That is, have a textBox display a
representation of a double precision number. I have tried (amoung other
things):

textBox2->Text=F.ToString;
all resulting in errors unintelegible by me.

Once again, the tried and true method in C/C++ is sprintf.
Don't knock it until you've tried it. For example:

char tempStr[128];
sprintf_s(tempStr, "%g", value);

Simple, portable (well, except for the _s part), and has more
possible options than you can shake a stick at.

If you want a C++ way (and not C (like Nathan Mates' solution) or .Net way), you can use stringstream or wstringstream (sprintf is
faster but is not type safe). See interpret_cast in Kevlin Henney's paper (Valued Conversions,
http://www.two-sdg.demon.co.uk/curbr...nversions.pdf). Also see lexical_cast (from the same author) in boost
libraries for an updated and more complete version of interpret_cast (http://www.boost.org/libs/conversion/lexical_cast.htm). These
converter templates are very flexible, simple and useful.

ToString is a function, not a property. The () are not optional in C++.
textBox2->Text=F.ToString();
