Hi all,

I need to
1. .Net dll with a method
   public bool myMethod (string inVal, ref StringBuilder outVal)
   {
               string temp = "test";
               int size = temp.Length;
               StringBuilder res = new StringBuilder(size);
               res.Append(Iterator.Current.Value);
               outVal = res;
   }

2. c++ program that calls this .Net dll

   LPWSTR* outVal;
   bool result = myMethod ("xyz",outVal);

I have not managed yet to get this working. I have a runtime error :

   Windows has triggered a breakpoint in ATLtest.exe.

   This may be due to a corruption of the heap, and indicates a bug in
ATLtest.exe or any of the DLLs it has loaded.

   The output window may have more diagnostic information

What is the correct way to pass strings from a COM component to a .Net,
modify the string in .Net, and pass it back again to the COM component ?
