 |
|
Hey,
I've been trying to convert a dword to hexa for the past few hours and haven't really succeeded.
Basically what I'm doing is this.
I get a value (type dword) from a pointer.
My objective is to convert this dword to hexadecimal. E.g. if value is 16, I want to convert it to 10 in hex.
I'm not exactly sure how one might do this in MASM32 since I only started probably a few months back, but I do know, in visual basic you can use the modulus and integer division operators to do it. I.e.
16 div 16 = 1
16 mod 16 = 0 (remainder)
1 div 16 = 0
1 mod 16 = 1 (remainder)
Reading remainder's backwards, decimal 16 = hexadecimal 10.
Does anyone know how to do this in MASM32? I'd greatly appreciate it.
Thanks,
-Sean

| Code: |
.data
lpHexString db "0123456789ABCDEF"
.code
Dec2Hex proc dwValue:DWORD, lpBuffer:DWORD
mov edi, lpBuffer
mov eax, dwValue
mov ecx, 8
.repeat
mov esi, eax
and esi, 0F0000000h
shr esi, 28
movzx edx, byte ptr [lpHexString+esi]
mov byte ptr [edi], dl
shl eax, 4
inc edi
.untilcxz
ret
Dec2Hex endp

Example:
| Code: |
invoke Dec2Hex, 1337C0DEh, addr lpBuffer
