    restoring a backup from a .BAK file is a administrative function and should be done manually from the management console.

    If you want to programmatically fill up a database, use regular SQL create/insert calls to do so.

    You can restore database only using appropriate SQL RESTORE DATABASE command.

    There is no any " VC++ syntax" for RESTORE DATABASE. There is SQL syntax.
    To execute such an SQL statement for DB restore you will have to use some of available functions (depends on the means you are using for DB connectivity) to execute SQL commands.
    So you connect to SQL server (note that your account must have CREATE DATABASE permissions!), then call a function to execute RESTORE DATABASE SQL script...

    the fact you want to restore a database from a .BAK means there is nothing to connect to (yet). This is why restoring from a BAK needs to be done at the management console.

    You can either use the UI to 'click your way' into doing this, or you can type the commands in the execution window of the cmanagement console. you can't do this over an ODBC connection.

    Depending on your SQL engine, there may be tools to do this remotely, and there may even be an API to do this from C++ code (remotely?). But it's not something you can do over ODBC.

    You must refer to MS SQL Server documentation instead of asking on forums with unpredictable results and answer quality.

    Actually the very first skill any developer must gain is ability to find answers in official software documentation sets.
