Code written in VBA is compiled [6] to Microsoft P-Code (pseudo-code), a proprietary intermediate language, which the host applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams.
Since the Leszynski naming convention is a special form of Hungarian notation the same general advantages also apply to the Leszynski convention.. The use of distinctive prefixes makes your database self-documenting; when you see frmSales in VBA code, you will know that it references a form, and when you see curSales you will know that it is a Currency variable.
Additionally, if the database design needs to be secured to prevent changes, Access databases can be locked/protected (and the source code compiled) by converting the database to a .MDE file. All changes to the VBA project (modules, forms, or reports) need to be made to the original MDB and then reconverted to MDE.
VBA was restored in the next version, Mac Excel 2011, [25] although the build lacks support for ActiveX objects, impacting some high level developer tools. [26] A common and easy way to generate VBA code is by using the Macro Recorder. [27] The Macro Recorder records actions of the user and generates VBA code in the form of a macro.
Recently, Racket has combined the notions of hygienic macros with a "tower of evaluators", so that the syntactic expansion time of one macro system is the ordinary runtime of another block of code, [23] and showed how to apply interleaved expansion and parsing in a non-parenthesized language.
A system of record (SOR) or source system of record (SSoR) is a data management term for an information storage system (commonly implemented on a computer system running a database management system) that is the authoritative data source for a given data element or piece of information, like for example a row (or record) in a table.
AutoNumber is a type of data used in Microsoft Access tables to generate an automatically incremented numeric counter. It may be used to create an identity column which uniquely identifies each record of a table.
Just My Code feature, which hides (steps over) boilerplate code written by the Visual Studio .NET IDE and system library code during debugging; Data Source binding, easing database client/server development; To bridge the gaps between itself and other .NET languages, this version added: Generics [18]
