I create the setup with the serial key & for validation of the key i have written function for validation.
i have all .dll & msi.lib

but i got the error as:
error : unresolved external symbol "unsigned int __stdcall MsiSetPropertyW(unsigned long,wchar_t const *,wchar_t const *)" (?MsiSetPropertyW@@YGIKPB_W0@Z) referenced in function "unsigned int __stdcall VerifyPID(unsigned long)" (?VerifyPID@@YGIK@Z) testdll.obj testdll

You need to get a book and/or article and/or tutorial about development of DLLs including how to set up a project to use a DLL. I would help you if I could but you need to know a little bit more before you can provide the details that we need to help you and so you can understand what we do say.
