// dapfTest

// Sample code for calling DinkeyAdd module

// The sample code contains 5 functions. You will not need to use all these functions in your code.
// Just use which ever are most appropriate and customise in your own way. The sample code
// is just a guide.  

// There are two methods to loading a DAPF file. These are shown in the first two functions:
// DoProgramDongle (simple) and DoProgramDonglewithMod (more complex)

// DoProgramDongle: we load the DAPF file from disk and get a handle and use it "as is" using the API
//                  call LoadDAPFFromFile. You can make some limited changes to overwrite the default
//                  behaviour by using API flags.
                     
// DoProgramDonglewithMod: we load the DAPF file from disk and load into structures. We can then modify the
//                         DAPF settings by modifying this structure. This method uses the API calls
//                         ReadDAPFEx and LoadDAPF.
                        
// The other functions use the first method (as it is simpler) but you can use the second method instead if
// you prefer.

// Note - an alternative to using the DoProgramDongleWithMod technique is to modify the DAPF file on disk
//        and then use the DoProgramDongle technique. To modify a binary DAPF you would use the binary structures
//        that are defined in dapf.h. To modify JSON DAPF you would need to use a JSON parser. In the case of
//        C/C++ we think it is easier to use the DoProgramDongleWithMod technique.

// DoLockSoftware: locks software (protect it) to a dongle as specified by the DAPF file.

// DoEncryptShellData: encrypts the shell data files specified in the DAPF file (this is used with encrypting
//                     data file if you use the Shell Method with "Data File Encryption" enabled).
                     
// DoCreateTempSoftwareKey: creates a Temporary Software Key based on the DAPF file and settings the user has entered. 

// DoCreateDemoSoftwareTemplate: creates a Demo Software Key Template based on the DAPF file and settings the user has entered
