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.
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
Both syntax-rules and syntax-case have been standardized in the Scheme standards. 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 ...
VBA code interacts with the spreadsheet through the Excel Object Model, [32] a vocabulary identifying spreadsheet objects, and a set of supplied functions or methods that enable reading and writing to the spreadsheet and interaction with its users (for example, through custom toolbars or command bars and message boxes).
The following example is done in Ada which supports both early exit from loops and loops with test in the middle. Both features are very similar and comparing both code snippets will show the difference: early exit must be combined with an if statement while a condition in the middle is a self-contained construct.
The API is usually specific to an application and incompatible to all others. So VBA-code written for MS-Office API can not be used in [[OpenOffice]} using the StarBasic-API for example, although StarBasic and VBA are very resemblant considering the language. Most software products (Autodesk AutoCAD / Microsoft Office / Adobe Illustrator ...
For example, the sequential model of the indexed loop is usually represented as a table of cells, with similar formulas (normally differing only in which cells they reference). Spreadsheets have evolved to use scripting programming languages like VBA as a tool for extensibility beyond what the spreadsheet language makes easy.
For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc. By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or even prevent certain ...
