Post subject: Method Link
|
|
Parents:
OptionalObjectInfo.aMethodLinkTable
| Code: | Type MethodLinkNative
jmpOpCode As Byte '0x0 (0d)
jmpOffset As Long '0x1 (1d) jmp <address> ; <address> = <currentoffset> + <jmpOffset> + 5
'0x5 (5d) <-- Structure Size
End Type |
| Code: | Type MethodLinkPCode
xorOpCode As Integer '0x0 (00d) xor eax, eax
movOpCode As Byte '0x2 (02d)
movAddress As Long '0x3 (03d) mov edx, <movAddress>
pushOpCode As Byte '0x7 (07d)
pushAddress As Long '0x8 (08d) push <pushAddress>
retOpCode As Byte '0xC (12d) ret
'0xD (13d) <-- Structure Size
End Type |
Notes:
* Teoricaly MethodLink can't be really treated as a structure, but since the OpCodes are always following same scheme, I choose to post these 'structures', just as guideline.
* These 2 structures are only valid for Native and PCode respectivaly.
* These 2 structures are only valid to: Sub, Function, Property Get and Property Let
* There isn't a structure for an API declaration.
* There is another 'structure' that can appear, and its related to Event declarations OR WithEvents declarations. (I do appreciate some help to debug this 'structure' more in depth).
Pointers:
Depending on the 'structure' the pointers could be the address of a native code method, could be the address of methodinfo for the PCode or could be an indirect pointer to VB Runtime.
