The standard CVF DLL code bombs out at startup if a DLL is not present along the path, and I need to make that optional in my programs. How do I do that? <BR /> <BR />Thanks <BR /> <BR />Steve Fri, 09 Mar 2001 09:04:06 GMT https://community.intel.com/t5/Software-Archive/Optional-DLLs/m-p/941884#M17240 Intel_C_Intel 2001-03-09T09:04:06Z https://community.intel.com/t5/Software-Archive/Optional-DLLs/m-p/941885#M17241 You use the Win32 API routines LoadLibrary and GetProcAddress.
