The MsiOpenPackage function opens a package for use with the functions that access the product database. The MsiCloseHandle function must be called with the handle when the handle is no longer needed.
UINT MsiOpenPackage(
LPCTSTR szPackagePath, // the full path to the package
MSIHANDLE *hProduct // returned product handle, must be closed
);
MsiOpenPackage can accept an opened database handle in the form "#nnnn", where nnnn is the database handle in string form, i.e. #123, in lieu of a path to the package. This is intended for development tasks such as running validation actions, or for use with database management tools.
