import library

I have an application that needs to import a DLL file for some
database call like -

#import "c:\Program Files\Common Files\System\ADO\msado15.dll" \
              rename("EOF", "EndOfFile")

the path is OS dependent - what if I run on some other PC but the
msado15.dll is not specificed in the path specified? for this case -
#import "c:\Program Files\Common Files\System\ADO\

any easy way to work around this problem where I don't have a hard
coded path in my code??

============

#import "c:\Program Files\Common Files\System\ADO\msado15.dll" \
              rename("EOF", "EndOfFile")

typedef ADODB::_RecordsetPtr RecPtr;
typedef ADODB::_ConnectionPtr CnnPtr;

class Database;
class Table;

class Database
{
public:
    CnnPtr m_Cnn;
    char m_ErrStr[500];
    Database();
    bool Open(char* UserName, char* Pwd,char* CnnStr);
    bool Execute(char* CmdStr, Table& Tbl);
    void GetErrorErrStr(char* ErrStr);
};

class Table{
public:
    RecPtr m_Rec;
    char m_ErrStr[500];
    Table();
    void GetErrorErrStr(char* ErrStr);
    int ISEOF();
    HRESULT MoveNext();
    HRESULT MovePrevious();
    HRESULT MoveFirst();
    HRESULT MoveLast();

    bool Get(char* FieldName, char* FieldValue);
    bool Get(char* FieldName,SYSTEMTIME& FieldValue);
    bool Get(char* FieldName,int& FieldValue);

    BOOL VariantTimeToSystemTimeWithMilliseconds (/*input*/ double
dVariantTime, /*output*/SYSTEMTIME *st);
};
