Hi guys & gals
I need to convert, in C#, a decimal hex string into an ascii string
(ie "56" -> "V"), and I can't find anything in the vs2003 help files
that is remotely helpful. Any suggestions that will save me writing my
own convert function would be gratefully received! 5 1198

Is it always a single character? If so, use:
char c = (char) int.Parse(origi nalString);

Hi Jon,
No, this doesn't work I'm afraid. It converts 56 to "8" rather than
"V", so it is obviously thinking that the 56 is decimal, not hex. Any
ideas please?

that will convert it from ASCII int to CHAR.
Try out this
char c = (char)int.Parse ("56",System.Gl obalization.Num berStyles.HexNu mber);

Ah, I was confused by your use of "decimal hex string" in the original
post. I didn't see the "hex" bit, just the "decimal" bit (and didn't
check the code for 'V').
In that case, use int.Parse(text, NumberStyles.He xNumber) (and cast to
char as before).
Alternatively, use Convert.ToInt32 (text, 16) (and cast).

Thanks guys for your virtually identical solutions. This worked well
I ended up putting it into a loop to get the whole string thus :-
string type = "";
for(int i=0;i<= hexstring.Lengt h-1;i=i+2)
{
type = type + (char)int.Parse (hexstring.Subs tring(i,2),
NumberStyles.He xNumber);
}
(And, yes, I know that I should have used stringbuilder, but I will
tidy up later!!)

Hello all,
Conversion macros along the name of INT8_C, INT16_C etc, are defined in
stdint.h to convert their argument into suitable representations for
their corresponding types, i.e. int8_t, int16_t etc.
My questions are:
1. Should the conversion macros be used even when assigning from a
variable of the same type?

I need to be able to enter a string and make it go to all lowercase. The only way I think you can do that is by first converting into char's. I've seen alot of "string to char array" but no simple solution. How do you (or where can I find, though I've looked) an answer to the following question....

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
