Summary

Add Vendor Defined Hostid Functionality to the C# Example

Synopsis

This articles shows how to add Vendor Defined Hostid(VDH) functionality to the checkout call in the C# sample application.

Discussion

The C# Application is useful for demonstrating how to perform trusted storage activations from a C# application using a C DLL and also checking out licenses from a license server.

Through some modification of the sample, you should also be able to test a VDH checkout from a license file based license server.

To do this, perform the following:

1. Follow the steps in the Programming reference guide for license file based licensing to setup your Flexnet Publisher(FNP) toolkit for VDH
2. Add the x_flexlm_newid(); call to the lmgract.c source code, as below:
   

   int WINAPI FNP_CreateJob()
   {
   if (lc_new_job(0, lc_new_job_arg2, &code, &lm_job))
   {
   return APICALL_FAILED;
   }
   x_flexlm_newid();
   return APICALL_SUCCESS;
   }

3. Add the a reference to the vendor_hostid.obj to the makefile.csharp file, as below:
   

   $(LMGRACT): $(LMGRDACTSRC)\lmgract.def $(LMGRDACTSRC)\lmgract.c $(ACTLIB) $(LMNEW_OBJ) $(CLIENTLIB)
   $(CC) $(CFLAGS) /I$(AAINCDIR) $(LMGRDACTSRC)\lmgract.c
   $(LD) /def:"$(LMGRDACTSRC)\lmgract.def" /out:lmgract.dll lmgract.obj vendor_hostid.obj /implib:"lmgract.lib" /dll $(LMNEW_OBJ) \
   lmgr$(SUFFIX).lib libsb$(SUFFIX).lib libcrvs$(SUFFIX).lib $(CLIENTLIB) \
   $(ACTLIB) $(ACTINSTALLERLIB) $(XTRALIB)
   $(PREPTOOL) -v $(LMGRDACTSRC)\lmgract.xml
   if exist lmgract.obj del lmgract.obj

4. Build the csharp example and test with a license file that contains a hostid from the vendor_hostid.c source code.
