https://community.intel.com/t5/Software-Archive/Optional-DLLs/m-p/942633#M17417 Hello, <BR /> I have an application that needs to optionally use Fortran DLLs. That is, it needs to test for their existence, and run one way of they are present and a different way if they are absent. In my case, the DLLs would contain classified code that could be deleted to produce an unclassified version of a program. <BR /> <BR /> The standard behavior of CVF 6.5 is to crash if all DLLs cannot be located at startup. How can I create "optional" DLLs for my code? <BR /> <BR />Thanks <BR /> <BR />Steve Wed, 14 Mar 2001 11:25:22 GMT Intel_C_Intel 2001-03-14T11:25:22Z https://community.intel.com/t5/Software-Archive/Optional-DLLs/m-p/942633#M17417 Hello, <BR /> I have an application that needs to optionally use Fortran DLLs.

Oh, yes, <A href="http://www7.compaq.com/forum?14@@.ee9d550">I did...</A><BR /><BR />The "standard behavior" you note is of Windows - CVF has nothing to do with it.<BR /><BR />What you want is to use the Win32 API routines LoadLibrary and GetProcAddress. CVF provides a sample DLLLOADEXP1 that demonstrates this.<BR /><BR />Steve Wed, 14 Mar 2001 11:28:42 GMT https://community.intel.com/t5/Software-Archive/Optional-DLLs/m-p/942634#M17418 Steven_L_Intel1 2001-03-14T11:28:42Z
