CString to HEX

[Benjamin Bruno]

Hi How to convert a CString value to HEX? eg: CString strHex = "0008103e"; to HEX value = 0x0008103e please help Thanks

An hex value doesn't exist, what you want probably is to convert a string representing an integer in hexadecimal notation to an integer. For this you can use strtol[^] function.

What Cedric said.

ULONG nVal;
CString str = _T("0x4335");
nVal = _tcstol(str, NULL, 0);

You got excellent C answers. In C++ use the facilities of the Standard C++ Library:

#include <sstream>
int GetIntFromHexString(const char* HexString)
{
int val;
std::istringstream(HexString) >> std::hex >> val;
return val;
}
