Doing Managed C++ Wrapper in VS2008. Have a native defined data structure as follows:
Code:
class API TF_StringList
{
public:
  TF_StringList(const char* encoding = "cp_1252");
    
  ~TF_StringList();

  TF_String* first_string() const {return start_string;}
  TF_String* last_string() const {return end_string;}

  void insert(const TF_String& aString);
  void insert(const char* aString);  

  // If the length parameter is larger than the size of the string,
  // The behavior is uncertain.
  void insert(const tf_Byte* aString, size_t aByteLength);

  void clear();

  size_t size() const { return list_size; }

  char* character_encoding;

private:
  
  void set_first(TF_String* stringPtr) {start_string = stringPtr;}
  void set_last (TF_String* stringPtr) {end_string = stringPtr;}

  TF_String* start_string;
  TF_String* end_string;
  TF_String* curr_pos;
  size_t list_size;


  // Do not expose the copy constructor and the assignment operator.
  TF_StringList(const TF_StringList& tmp);
  TF_StringList& operator=(const TF_StringList& tmp);

};
In one of my managed functions I have parameter of List<String^> categoryList and I want to load an object of type TF_StringList with the elements of that parameter.
Code:
//Instantiate the TF_StringList 
categories = new TF_StringList(); 
for(int i=0; i<categoryList.Count; i++) 
{ 
   const char* str = (const char*)(Marshal::StringToHGlobalAnsi(categoryList[i])).ToPointer(); 
   categories->insert(str); 
}
On the last line, I get the error:C2663: 'TF_StringList::insert' : 3 overloads have no legal conversion for 'this' pointer
First, The error would lead me to believe that str is not "seen" by the TF_StringList instance as a const char* since the insert(const char* aString) does not accept it.

Second, the list does not index out a Managed String (e.g. that String^ st = categoryList[i] is not valid). This seems unlikely since the declaration is List categoryList.

How can I check to find out what the problem actually is?
