I am building an application with the firebird 2.5 API.  I keep getting the following errors at compile time.  I am using VS 2005 on win 7.

Error    1    error LNK2028: unresolved token (0A00004B) "extern "C" int __stdcall isc_print_status(int const *)" (?isc_print_status@@$$J14YGHPBH@Z) referenced in function __catch$??0Form1@CallSheet@@$$FQ$AAM@XZ$0    CallSheet.obj

Error    2    error LNK2028: unresolved token (0A00004C) "extern "C" int __stdcall isc_attach_database(int *,short,char const *,void * *,short,char const *)" (?isc_attach_database@@$$J224YGHPAHFPBDPAPAXF1@Z) referenced in function "public: __clrcall CallSheet::Form1::Form1(void)" (??0Form1@CallSheet@@$$FQ$AAM@XZ)    CallSheet.obj

Error    3    error LNK2019: unresolved external symbol "extern "C" int __stdcall isc_print_status(int const *)" (?isc_print_status@@$$J14YGHPBH@Z) referenced in function __catch$??0Form1@CallSheet@@$$FQ$AAM@XZ$0    CallSheet.obj

Error    4    error LNK2019: unresolved external symbol "extern "C" int __stdcall isc_attach_database(int *,short,char const *,void * *,short,char const *)" (?isc_attach_database@@$$J224YGHPAHFPBDPAPAXF1@Z) referenced in function "public: __clrcall CallSheet::Form1::Form1(void)" (??0Form1@CallSheet@@$$FQ$AAM@XZ)

here is the code snippet where i get the errors:

                #include <string>
                #include <stdio.h>
                #include <stdlib.h>
                #include "ibase.h"
                #include "ib_util.h"
                #include "iberror.h"

                ***

                db1 = initDBhandle(db1);
                param_buffer = populate_dpb("SYSDBA", "masterkey");
                db_pathname = "..\\CallSheet_DB\\CallSheet.fdb";
                }
                catch(exception e){
                    if (status_vector[0] == 1 && status_vector[1]){
                        /* An error occurred. */
                        isc_print_status (status_vector);
                    }
                }


I have done extensive searching on the web for a solution to this.  Near as I can tell, I am missing an library file of some sort with the actual functions in them.
Any help would be greatly appreciated. If you need more info please ask

Thanks
