[英]Hex Dump Utility C++ Displaying Hex and Ascii
好的,所以我調用讀取文件來填充斜坡槽,但它僅適用於.txt或.bin文件,並且在我打開其他任何內容(例如錯誤代碼為0xC0000005的.doc文件)時會崩潰:執行位置0xFFFFFFFF的訪問沖突。
這也是顯示屏幕的十六進制和ascii轉儲的正確方法嗎?
//The slop_trough I dump all the hex and ascii slop into
unsigned char slop_trough [MAX] = {0} ;
void ReadFile (string filename, unsigned char slop_trough [])
{
ifstream open_bin;
open_bin.open( filename, ios::in | ios::binary ) ;
if ( open_bin.is_open() )
{
open_bin.read ( reinterpret_cast <char *> (slop_trough),
sizeof(slop_trough) * MAX ) ;
open_bin.close();
}
else
cout << "File not opened!" << endl;
}
void HexDump (unsigned char slop_trough [])
{
for ( int j = 0; j < MAX - 1; ++j)
{
cout << hex << slop_trough[j] ;
}
}
void AsciiDump(unsigned char slop_trough [])
{
for ( int p = 0; p < MAX - 1; ++p)
{
cout << slop_trough[p];
}
}
嘗試這樣的事情:
streamsize ReadFile (const string &filename, unsigned char *slop, int max_slop)
{
ifstream open_bin;
open_bin.open( filename, ios::in | ios::binary ) ;
if ( !open_bin.is_open() )
{
cout << "File not opened! " << filename << endl;
return 0;
}
if( !open_bin.read ( reinterpret_cast<char*>(slop), max_slop ) )
{
cout << "File not read! " << filename << endl;
return 0;
}
return open_bin.gcount();
}
void HexDump (unsigned char *slop, streamsize slop_len)
{
for ( int j = 0; j < slop_len; ++j)
{
cout << noshowbase << hex << setw(2) << setfill('0') << slop[j] << ansi::reset();
cout.put(' ');
}
cout << dec << setw(0) << setfill(' ');
}
void AsciiDump(unsigned char *slop, streamsize slop_len)
{
for ( int p = 0; p < slop_len; ++p)
{
if ( (slop[p] > 0x20) && (slop[p] < 0x7F) && (slop[p] != 0x0A) && (slop[p] != 0x0D) )
cout << slop[p];
else
cout << '.';
}
cout << ansi::reset();
}
//The slop_trough I read the file data into
unsigned char slop_trough [MAX] = {0} ;
streamsize slop_len = ReadFile ( "filename", slop_trough, MAX );
unsigned char *slop = slop_trough;
while ( slop_len >= 16 )
{
HexDump ( slop, 16 );
cout << "| ";
AsciiDump( slop, 16 );
cout << endl;
slop += 16;
slop_len -= 16;
}
if ( slop_len > 0 )
{
HexDump ( slop, slop_len );
cout << left << setw(48 - (slop_len * 3)) << setfill(' ') << "| ";
AsciiDump( slop, slop_len );
}
