Today I will check the localized settings. That could be one possible solution.
The C-Environment and the LabView environment are running on two differnt PCs. But I am sure, they are using the same MSVC libraries because I installed them on both PCs from the same CDROM. You ask me, if the string I passed to the DLL is ok? I do not pass any string into the DLL. A function within the DLL reads the strings out of an INI file and converts all necessary parameters to a double value (atof). These parameters are completly used within the DLL. There is no exchange between LV and the DLL. Sven Bone
