I have a template defined similar to this

template <typename K, typename T>
class myclass
{
...
}

Now, when values of type K are sent in, I want to convert the value of K to
a string. But, I need to know the type. If K is a string, then I don't need
to change anything. If K is an integer, the I'll use IntToStr, if K is a
double I can use FormatFloat. But how do I determine K's type. I tried using
typeid in a series of if/else statements, but it won't compile. Any
ideas????

thanks, Brian

You can use the automatic conversions for AnsiString.
as in:
AnsiString Str = 1;
AnsiString Str = 1.1;
