Hello,

   I received a C++ DLL and I must include it in my C# programm. The
problem is that I don't know how to convert the parameters from C++ to C#,
specialy when there are pointers in it. There are 2 fonctions I would like
to convert.

   The first one has only one parameter, but I don't know how to deal with
the void type.

[C++]
long myFunction1(void ** parameter);

   I tried this, but it does not work:

[C#]
[DllImport("MyDLL.dll")]
public static extern long myFunction1(ref IntPtr parameter);

   The second one has a double pointer to a structure. I think I dealed
with the structure, but what about the double pointer ?

[C++]
long myFunction2(myStruct** parameter);

with myStruct defined as:

struct FF_AO_ImageList
   {
   char structParameter1[30];
   long structParameter2;
   }

[C#]
[DllImport("MyDLL.dll")]
public static extern long myFunction2(??????);

with myStruct defined as:

public struct FF_AO_ImageList
   {
   [MarshalAs(UnmanagedType.ByValTStr), SizeConst = 30]
   public string structParameter1;
   public long structParameter2;
   }

   I hope it's not too difficult to understand, however I'll explain again.
I hope someone can help me ! Thanks...
