5. Libraries The Client Server Communication Library component is a Win32 dynamic link library DLL A DLL is characterized by the fact that it need not be loaded until required by an application program and that only one copy of the DLL is necessary regardless of the number of application programs that use it Contrast this to the traditional static library that is bound to each and every application that uses it at link time An important advantage that DLLs have over other popular library formats such as VBX or OCX is that DLLs are callable by all Windows applications Since DLLs are the building blocks of the Windows Operating System they will not be replaced by a newer technology The following files can be found in the DLL sub directory when SETUP is run esc32 dll Win32 version of CSC csc64 dll Win64 version of CSC 2 2 Keycode CSC32 DLL has a keycode encoded within it The keycode is a 9 or 10 digit decimal number unless it is 0 and will be found in the file KEYCODE PAS The keycode for the evaluation version is 0 You will receive a new key code when registering The KEYCODE is passed to cscAttach If an error message value 74 is returned when calling escAttach it means that the keycode in the CSC application does not match the keycode in the DLL After registering it is best to remove the evaluation version of the CSC32 DLL and CSC64 DLL from the Windows search 2 3 Win32 STDCALL and DECLSPEC CSC is written in ANS
