As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
Code statements have no terminating character other than a line ending (carriage return/line feed), and versions since 3 allow for multi-line statements for concatenation of strings or explicitly using the underscore character (_) at the end of a line [15] [16] A code comment is denoted by a single apostrophe (') character, like: ' This is a ...
The things that have changed significantly are the semantics—from those of an object-based programming language running on a deterministic, reference-counted engine based on COM to a fully object-oriented language backed by the .NET Framework, which consists of a combination of the Common Language Runtime (a virtual machine using generational ...
Like VBA, code written for VSTO is executed by a separate virtual machine (the CLR) which is hosted inside the Microsoft Office applications. However, unlike VBA, where the code is stored in the document file itself, programs written with VSTO are stored in separate CLI assemblies which are associated with the documents by means of custom properties.
These actions can then be repeated automatically by running the macro. The macros can also be linked to different trigger types like keyboard shortcuts, a command button or a graphic. The actions in the macro can be executed from these trigger types or from the generic toolbar options. The VBA code of the macro can also be edited in the VBE.
In computing, the exit status (also exit code or exit value) of a terminated process is an integer number that is made available to its parent process (or caller). In DOS , this may be referred to as an errorlevel .
The running environment is embeddable in other programs via the Microsoft Script Control (msscript.ocx). VBScript has been installed by default in every desktop release of Microsoft Windows since Windows 98 ; [ 2 ] in Windows Server since Windows NT 4.0 Option Pack ; [ 3 ] and optionally with Windows CE (depending on the device it is installed on).
In computer programming, unreachable code is part of the source code of a program which can never be executed because there exists no control flow path to the code from the rest of the program. [ 1 ] Unreachable code is sometimes also called dead code , [ 2 ] [ 3 ] although dead code may also refer to code that is executed but has no effect on ...
