true if succeed

Examples

EX1

void BitsHex_BitsToHexStr_ex1()
{
	vector<byte> vb;
	int nTotal = 20; //the vector will be converted to 5 Hex chars.
	srand( GetTickCount() );
	for ( int ii = 0; ii < nTotal; ii++ )
	{
		byte tb = rand() % 2;
		vb.Add(tb);
	}
	string strHex;
	BitsHex bh;
	if ( !bh.BitsToHexStr(vb, strHex) )
	{
		printf("Fail to convert vector to Hex string.");
		return;
	}
	printf("vector {%d, ", vb[0]);
	for ( ii = 1; ii < nTotal - 1; ii++ )
		printf("%d, ", vb[ii]);
	printf("%d} is convert to Hex string as follows:\n", vb[ii]);
	
	printf("%s\n", strHex);
