DllStructCreate and rect struct

[monoceres]

Hello!

I'm having some problems translating a struct declared in delphi to autoit:

AVI_STREAM_INFO = packed record
      fccType : DWORD;
      fccHandler : DWORD;
      dwFlags : DWORD;
      dwCaps : DWORD;
      wPriority : word;
      wLanguage : word;
      dwScale : DWORD;
      dwRate : DWORD;
      dwStart : DWORD;
      dwLength : DWORD;
      dwInitialFrames : DWORD;
      dwSuggestedBufferSize : DWORD;
      dwQuality : DWORD;
      dwSampleSize : DWORD;
      rcFrame : TRect;
      dwEditCount  : DWORD;
      dwFormatChangeCount : DWORD;
      szName : array [0..63] of char;
  end;

As you can see it's not very advanced and mostly it's just a whole bunch of dwords

But then I come to rcFrame which is supposed to be a TRect.

TRect seems to be a the delphi equivalence of a regular rect struct (int x1, int y1, int x2, int y2)

But even if I create a rect struct, how would I use it in my other struct?

Anyways any ideas?

Thanks!

Will this work?

$trect = DllStructCreate("int x1; int y1; int x2; int y2")
if @error Then
    MsgBox(0,"","Error in DllStructCreate " & @error);
    exit
endif

$str = "DWORD fccType;"
$str&= "DWORD fccHandler;"
$str&= "DWORD dwFlags;"
$str&= "DWORD dwCaps;"
$str&= "word wPriority;"
$str&= "word wLanguage;"
$str&= "DWORD dwScale;"
$str&= "DWORD dwRate;"
$str&= "DWORD dwStart;"
$str&= "DWORD dwLength;"
$str&= "DWORD dwInitialFrames;"
$str&= "DWORD dwSuggestedBufferSize;"
$str&= "DWORD dwQuality;"
$str&= "DWORD dwSampleSize;"
$str&= $trect & " rcFrame;"
$str&= "DWORD dwEditCount;"
$str&= "DWORD dwFormatChangeCount;"
$str&= "var[64] szName;"

$struct2 = DllStructCreate($str)
if @error Then
    MsgBox(0,"","Error in DllStructCreate " & @error);
    exit
endif

Nope

@error = 2 Element value out of range.

I'm not very proficient with this dll stuff...I also can't find much about nested structs. I'm not even sure AutoIt can handle this type of thing due to the lack of OOP.

$trect = DllStructCreate("int x1; int y1; int x2; int y2")
if @error Then
    MsgBox(0,"","Error in DllStructCreate " & @error);
    exit
endif

$str = "DWORD fccType;"
$str&= "DWORD fccHandler;"
$str&= "DWORD dwFlags;"
$str&= "DWORD dwCaps;"
$str&= "word wPriority;"
$str&= "word wLanguage;"
$str&= "DWORD dwScale;"
$str&= "DWORD dwRate;"
$str&= "DWORD dwStart;"
$str&= "DWORD dwLength;"
$str&= "DWORD dwInitialFrames;"
$str&= "DWORD dwSuggestedBufferSize;"
$str&= "DWORD dwQuality;"
$str&= "DWORD dwSampleSize;"
$str&= "ptr " & DllStructGetPtr($trect) & ";"
$str&= "DWORD dwEditCount;"
$str&= "DWORD dwFormatChangeCount;"
$str&= "var[64] szName;"

$struct2 = DllStructCreate($str)
if @error Then
    MsgBox(0,"","Error in DllStructCreate " & @error);
    exit
endif

Still @error=2

Hope Siao will pop in and clear up the situation, he's really good at this

Rect as part of another structure is just the same as Rect alone. 4 ints in a row.

If you want, you can group them into

int Rect[4]

If you still need examples, take a look at files in Include folder. It has to be used there quite a lot.
