Hello,

In activex.pp, the GetMarshalSizeMax method is defined as:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i        
Function GetMarshalSizeMax ( Const Riid: TIID; {in, unique}
pv:Pointer; Const dwDestContext : DWord;                   {in,
unique} pvDestContext:Pointer; Const mshlflags : DWord; out pSize :
PDWord ): HResult;Stdcall; Note the last parameter is declared as "out
pSize : PDWord" since it is "out", it should be declared as "out pSize
: DWord" (no P in DWord).

HTH.
