编译连接可以生成Service.exe程序.(后附整个工程)
现在我们已经得到了实现功能的两个程序,kernel.exe是在Win9X系统下实现功能的程序,Service.exe是Win2000/XP下实现功能的程序.现在就要将这两个文件转化成１６进制代码．可以通过一个程序来实现，建立一个名为exe2hex的Win32 Console Application程序，程序代码如下：
#include <stdio.h>
#include <windows.h>
int main(int argc,char **argv)
{
HANDLE hFile;
DWORD dwSize,dwRead,dwIndex=0,i;
unsigned char *lpBuff=NULL;
__try
{
if(argc!=2)
{
printf("/nUsage: %s <File>",argv[0]);
__leave;
}

hFile=CreateFile(argv[1],GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
if(hFile==INVALID_HANDLE_VALUE)
{
printf("/nOpen file %s failed:%d",argv[1],GetLastError());
__leave;
}
dwSize=GetFileSize(hFile,NULL);
if(dwSize==INVALID_FILE_SIZE)
{
printf("/nGet file size failed:%d",GetLastError());
__leave;
}
lpBuff=(unsigned char *)malloc(dwSize);
if(!lpBuff)
{
printf("/nmalloc failed:%d",GetLastError());
__leave;
}
while(dwSize>dwIndex)
{
if(!ReadFile(hFile,&lpBuff[dwIndex],dwSize-dwIndex,&dwRead,NULL))
{
printf("/nRead file failed:%d",GetLastError());
__leave;
}
dwIndex+=dwRead;
}
for(i=0;i<dwSize;i++)
{
if((i%16)==0)
if(i==0)
printf("/"");
else
printf("/"/n/"");
printf("//x%.2X",lpBuff[i]);
}
printf("/"");
}//end of try
__finally
{
if(lpBuff) free(lpBuff);
CloseHandle(hFile);
}
return 0;
}
编译出可执行文件exe2hex.exe,执行exe2hex kernel.exe >kernel.txt将输出结果重定向到一个文本文件就得到了kernel.exe的16进制代码，同理可以得到Service.exe的16进制代码.
啊，写了这么多还真有点累了，不过还好总算要完成了，歇口气.最后我们来编写主程序funny.exe:
