Can I use the DEScipher DLL in Visual Basic?
The current 32-bit version of DEScipher/DLL uses the “standard” (aka “Pascal”) calling convention which is supported in Visual Basic. Older releases of the DLL used the “C” calling convention, and are not compatible with Visual Basic. All versions of TDEScipher use the “standard” calling convention, and therefore are compatible with VB (see next question).
