Running Fortran from Excel VBA for Engineers and Scientists

Boost your skills with our Excel VBA Fortran class.

Our 3-day class shows how to create powerful tools by combining the speed of Fortran with the GUI, data, and modeling abilities of Excel VBA. It shows how to use the key Excel VBA and text file elements necessary to process, pass, return, and display Fortran DLL data.
Also covered is how to design and compile Fortran DLLs or upgrade existing Fortran code to run from VBA. Our class also discusses how to automate Excel's data tools and charts; build models; and create GUIs from userforms, shapes, worksheets, and ActiveX to run Fortran DLLs.
