Convert CDatabase to CDatabase*

[Huskey]

Hi,

can anyone please tell me how to convert a database defined in CDatabase to a CDatabase* instead. Also, what are the differences?

Many thanks!!!!

That is a pointer of CDatabase.
What do you need it for?If you have to pass it as an argument to a function use '&' before your CDatabase object.

Dear Viorel,

Thank you for your reply. My question is actually how to pass an information of CDatabase from a CDialog class to the another class which define the database as CDatabase*.

For example, I have a CDialog class which is defined as:
CDatabase db; (defined in the header)
db.Open(NULL,false,false,"ODBC;",TRUE);
....

I have another class which needs the information from the opened database. The declaration:

Header file:

Protected:
CDatabase *database_;

Database Parameter:
CDatabase *GetDatabase() const {return database_;}

When I tried to use this GetDatabase() in my CPP file to retrieve the information, I got NULL in return. Please help if you can.

cheers,
