Access memmory from VB?
Fra : Casper Bang


Dato : 28-02-01 22:08

In VB, how do I access the memmory at a given offset and read/write the hex
values?

Thanks,
Casper

I guess this is what you want :-


Private Declare Sub MoveMemory _
Lib "KERNEL32" _
Alias "RtlMoveMemory" _
(ByVal Dest As Any, _
ByVal Source As Any, _
ByVal Bytes As Long)

Private Declare Sub MoveString _
Lib "KERNEL32" _
Alias "RtlMoveMemory" _
(Dest As Any, _
ByVal Source As String, _
ByVal Bytes As Long)


Private Sub Poke(MemLoc&, B As Byte)
Call MoveMemory(MemLoc, VarPtr(B), 1)
End Sub

Private Function Peek(MemLoc&) As Byte
Dim Q As Byte
Call MoveMemory(VarPtr(Q), MemLoc, 1)
Peek = Q
End Function

Private Sub Command1_Click()
Dim A%

A = 255
MsgBox Str$(Peek(VarPtr(A)))
Poke VarPtr(A), 1
MsgBox Str$(A)
End Sub
