DllStructCreate

[Oldschool]

From MSDN:

BOOL WINAPI GetConsoleScreenBufferInfo(
  __in   HANDLE hConsoleOutput,
  __out  PCONSOLE_SCREEN_BUFFER_INFO lpConsoleScreenBufferInfo
);

;------------------------------------------------------;
CONSOLE_SCREEN_BUFFER_INFO Structure

typedef struct _CONSOLE_SCREEN_BUFFER_INFO {
  COORD dwSize;
  COORD dwCursorPosition;
  WORD wAttributes;
  SMALL_RECT srWindow;
  COORD dwMaximumWindowSize;
} CONSOLE_SCREEN_BUFFER_INFO;

;-----------------------------------------------------;
SMALL_RECT Structure

typedef struct _SMALL_RECT {
  SHORT Left;
  SHORT Top;
  SHORT Right;
  SHORT Bottom;
} SMALL_RECT;

;----------------------------------------------------;
COORD Structure

typedef struct _COORD {
  SHORT X;
  SHORT Y;
} COORD, 
 *PCOORD;

So...based on the MSDN info these

COORD dwSize;

COORD dwCursorPosition;

SMALL_RECT srWindow;

COORD dwMaximumWindowSize;

should equal

$dwSize = DllStructCreate("short;short")
$dwCursorPosition = DllStructCreate("short;short")
$srWindow = DllStructCreate("short;short;short;short")
$dwMaximumWindowSize = DllStructCreate("short;short")oÝ÷ Ù»­²)Ü{jz'*Z²Ê'y+k¹Ëi¢)íz¸§¶´*'²^IÊÞzpn}÷«"wèËaÇ(®·¶Ø^«­¢+ØÀÌØí

No one knows the answer?? Any other example of a multilevel struct will do...

It looks correct to me. Have you passed DllStructGetPtr?

Right now I'm having trouble getting a handle to the console screen buffer, so I'm not sure if the struct fills right or not...

[Oldschool]

$stdOutHandle = _WinAPI_GetStdHandle(1)
If Not $stdOutHandle Then MsgBox(0, "", "Error getting std handle...")
$CONSOLE_SCREEN_BUFFER_INFO = DllStructCreate("short;short,short;short;short;short,short;short;short;short;short")
DllCall("Kernel32.dll", "int", "GetConsoleScreenBufferInfo", "int", $stdOutHandle, "ptr", DllStructGetPtr($CONSOLE_SCREEN_BUFFER_INFO))
If @Error Then MsgBox(0, "", "Error during dll call...")
MsgBox(0,"",DllStructGetData($CONSOLE_SCREEN_BUFFER_INFO, 2))

Always returns 0 for example...

Although this supposedly works:

{

  cchWidth = -1;
  cchHeight = -1;
  const int STD_OUTPUT_HANDLE = -11;

  CONSOLE_SCREEN_BUFFER_INFO csbi;
  if ( GetConsoleScreenBufferInfo( GetStdHandle( STD_OUTPUT_HANDLE ), out csbi ) )
  {
    cchWidth = csbi.dwSize.X;
    cchHeight = csbi.dwSize.Y;
    return true;
  }
  return false;

}

Just so anyone looking for the answer actually gets one...  The above code is almost correct.  There is just a mistake in the structure.  This works:

$stdOutHandle = _WinAPI_GetStdHandle(1)
If Not $stdOutHandle Then MsgBox(0, "", "Error getting std handle...")
$CONSOLE_SCREEN_BUFFER_INFO = DllStructCreate("short;short;short;short;word;short;short;short;short;short;short")
DllCall("Kernel32.dll", "int", "GetConsoleScreenBufferInfo", "int", $stdOutHandle, "ptr", DllStructGetPtr($CONSOLE_SCREEN_BUFFER_INFO))
If @Error Then MsgBox(0, "", "Error during dll call...")
MsgBox(0,"","Height = "&DllStructGetData($CONSOLE_SCREEN_BUFFER_INFO, 2))
