I have many applications that might use the functionality of the SVT Octave Analysis VI. I have wrapped the VI in a DLL to call from VC++8.0. I am able to pass the data into the VI and it does the work but the filters NEVER settle. I put the DLL into LabVIEW and they settled in the expected time. I have a little more experience with dlls that are created in VC++. I am wondering if there is a runtime library that I need to load in addition to the dll? It worked with the LabVIEW Prop but not VC++ and the only difference was that LabVIEW was running.
Do you have the LabVIEW Run-Time Engine installed on the computer you are using the LabVIEW DLL? If so, make sure the version of the run-time engine matches the version of LabVIEW that you developed the DLL. Consult the KnowledgeBase article titled LabVIEW Run-Time Engine Requirements for DLL Execution for more information.
