Trouble with imports in VB windows application

[Beerdude]

Im trying to create a windows application in VB .net and im having some trouble accessing some of the available functions. Im trying to use the isalpha function (among others) - which are in the ctype.h library (in C++). But Im stumped as to how to include or import it. Adding a reference to Visual C++ didnt seem to work, do I put an #include or imports at the top or something? Thanks for your help

You cant include a C/C++ header in a VB application. You could call a DLL written in C/C++ that contains a wrapper for that function - but not call it direct.

You shouldnt need to do that anyway, Char has shared members like IsDigit, IsLetter, IsDigitOrLetter, etc..
