常用函数库——调试函数

采用消息对话框以16进制的形式输出一段连续内存中的数据

应用环境：C++ MFC工程

 

void HexDump(char *buf, DWORD len, DWORD addr)
{
	DWORD i,j,k;
	CString strPrint;
	for(i = 0; i < len, i++)
	{
		if(0 == i%16)
		{
			strPrint.Format("%08x -", i+addr);
			strPrint.Format("%s  %02x", strPrint,(unsigned char)buf[i]);
		}
		else if(15 == i%16)
		{
			strPrint.Format("%s %02x  ", strPrint, (unsigned char)buf[i]);
			for(j = i - 15; j <= i; j++)

				strPrint.Format("%s%c", strPrint, buf[j]);
