f90VB Example Programs

This page contains some simple examples to show some of the features of f90VB. You can find many more examples in the f90VB User Manual and the Reference Manual.

Examples for the BStrings Library:

• Simple BStrings manipulation (BStrAllocExamples)
• Simple Mixed strings concatenation (StrConcatExamples)
• Using subroutine StrCopy (StrCopyExamples)
• Passing BStrings from Visual Basic to Fortran DLLs (Example 4.2). This is a step-by-step example.

Examples for the SafeArrays Library:

• Using subroutine SafeArrayCreate and mapping Safe Arrays into Fortran Arrays using SafeArrayAccessData (SafeArrayCreateExamples)
• Obtaining information about a Safe Array and mapping Safe Arrays into Fortran Arrays (SafeArrayGetInfo)
• Beat Visual Basic sluggish math, create a Safe Array multiplication DLL using Fortran (Example 4.4). This is a step-by-step example.

Examples for the Variants Library:

• Using function VariantCreate (VariantCreateExample)
• A Fortran function that can compute the Sine of almost anything :-) and how to use it from Visual Basic (Example 4.5). This is a step-by-step example.

Examples for the Automation Library:

• Controlling Internet Explorer from your Fortran applications (Example 6.1).
• Create neat excel spreadsheets and charts from your Fortran programs (Example 6.3). This is a step-by-step example.
• Handling Automation events from Fortran (Example 6.5). This is a step-by-step example.
• Creating a Visual Basic GUI for your Fortran applications. To come on a later date...
