Hi, community!

When I have got a WORD variable that contains a hex-value and I need this value as int to calculate with it, how do I convert it?
And how do I convert any numeric type variable into CString in order to control the value in a MessageBox?

Hi BoogieBoy,

numeric variables do not differ between a hex or a decimal or something. Hex is just how an app shows a value. I.e.

ASSERT( 0x0f == 15 ); // will always be true

to convert a numeric value to a CString you can use CString::Format(), i.e.

....
int x = 123456789;
double f = 12345.6789;
CString t;
t.Format( "x = %d (hex:0x%08X), f = %f (%e).", x, x, f, f );

sets t to:
"x = 123456789 (hex:0x075BCD15), f = 12345.678900 (1.234568e+004)"

hope that helps,

ZOPPO
