Here is my constructor and the rest. I am really puzzled about this.

#include "InsertDependency.h"

InsertDependency::InsertDependency()
{
_ID = "";
_MustBeforeLink = "";
}

InsertDependency::InsertDependency(string ID, string MustBeforeLink)
{
_ID = ID;
_MustBeforeLink = MustBeforeLink;
}

Is 'string' the std::string?

In your first post in the thread you wrote:

InsertDependency* pInsertDependency = new InsertDependency((LPCTSTR) ID,
(LPCTSTR) MustBeforeLink);

in this case the LPCTSTR cast is wrong.

If you want LPCTSTR strings, you may consider using CString from ATL/MFC
instead of std::string...

string& InsertDependency::GetID()
{
return (_ID);
}

I would define a const GetXxxx method, e.g.

  LPCTSTR InsertDependency::GetID() const
  {
      return ((LPCTSTR) _ID); // assume "CString _ID" data member
  }

If you want to modify the string values, you can implement a separate
SetXxxxx method.
