As far as i know there is no datatype called hexadecimal. What is the actuaal data type wheather its Int, long, or string if its string then you need to convert it to long or int and use the following statemetn printf("%d",nHexNum); or printf("%ld",lHexNum); Which ever fits rite.

No, but there are base-16 numbers, also known as hexadecimal numbers. Referring back to styve's post, he wanted to convert a base-16 number (hexadecimal) to a base-10 number (decimal).

I certaily agree with you? I was trying to be within the context of C/C++, Many newbies consider this as hexadecimal no. int x = 0xff; ;)

What you mean by hexadecimal 2b67 ??? From the machine, it's just the same than 11111 in base-10... The hexadeciaml is just the way YOU represent the number. But for the machine, it just sees 0's and 1's.

As I understand you are trying to get hexadecimal equivalent of numeric, as mentioned by others; all data in memory stayed in hexadecimal format, the issue is to display that in hexadecimal acsii char array, take a look below; DWORD dwTest; char a[20]; dwTest=0xAABBCCDD; sprintf(a,"%x",dwText); AfxMessageBox(a);
