the codes only worked the buffer of Ascii.
Code Select
HexAsciiDump proc uses ebx esi edi inAddr:DWORD,nparagraphs:DWORD,fZeroBase:DWORD,outAddr:dword
LOCAL temp[4]:byte

invoke RtlZeroMemory,addr temp,4

mov esi, inAddr
mov ecx, nparagraphs
test ecx, ecx

thanks all who respondid my question.
here is a code of HexAsciiDump. and works fine.
Code Select
HexAsciiDump_1 proc uses esi edi ebx pData:DWORD, dwOffset:DWORD, dwSize:DWORD
local dwCurrentOffset:DWORD
local AsciiBuffer:DWORD
local BufferSize:DWORD

.data
szFmt db "%08X  %02X %02X %02X %02X %02X %02X %02X %02X - %02X %02X %02X %02X %02X %02X %02X %02X  ", 0

.code

xor edx,edx
mov eax,dwSize
mov ecx,6
mul ecx
mov BufferSize,eax
invoke GetProcessHeap
invoke HeapAlloc, eax, HEAP_NO_SERIALIZE + HEAP_ZERO_MEMORY, BufferSize
.if eax != NULL

mov AsciiBuffer, eax
mov edi, eax

invoke RtlZeroMemory, edi, BufferSize
mov esi, pData
push dwOffset
pop dwCurrentOffset
mov ebx, dwSize
.if ( esi != NULL ) && ( ebx != 0 )

shr ebx, 4 ; / 16 - number of 16-byte lines to print
inc ebx

.while ebx
mov ecx, 16
xor eax, eax
.while ecx
dec ecx
mov al, [esi][ecx]
push eax
.endw
push dwCurrentOffset
push offset szFmt
push edi ; current pointer to text buffer
call wsprintf
add esp, 04Ch

add edi, eax ; shift current pointer to next free place

xor ecx, ecx
.while ecx < 16
mov al, [esi][ecx]
.if al < ' '
mov al, '.'
.elseif al > '~'
mov al, '.'
.endif
stosb
inc ecx
.endw

; New line
mov al, 0Dh
stosb
mov al, 0Ah
stosb

add esi, 16 ; next 16 bytes
add dwCurrentOffset, 16 ; next 16 bytes
dec ebx ; next line
.endw

invoke SetDlgItemText,XMAIN_hWnd,IDC_SHOWEDIT,NULL
invoke SetDlgItemText,XMAIN_hWnd,IDC_SHOWEDIT,AsciiBuffer

.endif

invoke GetProcessHeap
invoke HeapFree, eax, HEAP_NO_SERIALIZE, AsciiBuffer
.endif

ret

HexAsciiDump_1 endp


but i think the method of table searching better than the method of wsprintf.
