Move() error

[WojTec]

I have some code:

Delphi-Quellcode:

Len: DWORD;
Ptr: PByte;

Move(Len, Ptr[0], 4);
Move(Len, Ptr[4], 4);

Error: array type required. I tried in 7 and 2010.
What to do with this? Please, help.

What do you want to do?

If you want do use an index [0] or [4] you need an array type, not just a pointer (PByte).

E.g.:

Delphi-Quellcode:

var
  Ptr : array [0..4] of PByte;

Dont forget to allocate memory (e.g. using AllocMem, GetMem) before you use the pointer.

Hm, PByteArray is working I got code with PByte and its author told is working...

2 * DWORD = 8 Byte and not 5 * PByte .

Delphi-Quellcode:

var
  MyData : array [0..7] of Byte;

Delphi-Quellcode:

var
  TMyTyp = array [0..7] of Byte; 
  TMyPtr = ^TMyTyp;

But why Move, and not directly?

Delphi-Quellcode:

var
  Ptr: array [0..1] of DWORD;

Ptr[0] := Len;
Ptr[1] := Len;
