Using it with other programming languages

Any language which allows you to access a dynamic link library (DLL file) should be able to use VSPDCTL.DLL. Note that the strings these functions use are null-byte terminated (C-style) strings; if your language uses a different type of string, you may have to add the null-byte (a byte with the ASCII value of zero) to the end of them manually. Please consult your language documentation for further details.
