Convert CString to hexadecimal

You could convert your input string using strtoint, it accepts decimal or hex numbers, here's a link to the msdn help:-

:)

If you want a C++ solution then consider using a stringstream and the std::hex manipulator.

For example to convert a string of hex digits into a number:

std::string hex( "6a204687" );
std::stringstream str( hex );
unsigned number = 0;
str >> std::hex >> number;

One other thought, you might like to implement a DDX_hex function to complement the other DDX_ functions MFC gives you for exchanging hex numbers with controls in a dialogue box.
