Interfacing Excel VBA with Fortran

About our manual.

  Our Excel VBA Fortran manual covers how to create Fortran DLLs that run from Excel VBA models, UIs, and data tools. It discusses how to call Fortran from Excel VBA procedures, events, and User Defined Worksheet Functions (UDFs) that run from worksheet formulas. Think of the modeling possibilities, running 10,000 lines of high powered Fortran code from one worksheet cell.

Specifically, our manual documents in detail the Excel VBA and Fortran calling rules like compiler directives, declare statements, argument list design, and argument data typing. It focuses on those elusive rules for passing arrays, strings, numbers, complex numbers, Booleans, dates, and text files between VBA and Fortran. It also shows how to convert existing Fortran programs to a DLL standard and how to compile DLLs using Visual Studio and Intel Fortran.

Our manual also includes our complete write-up on beginning through advanced Excel VBA topics along with UI design using the worksheet, drawing shapes, ActiveX controls, userforms, and shapes. Also discussed are data topics like multi-workbook data processing and automated chart building which are key to using Excel as a Pre/Post processor of Fortran data. It also shows how to assemble and control advanced models with VBA and how to combine Fortran with Solver for design optimization projects.
