My inputs are LV I32 controls. For the library function node, I'm using Signed 32 bit Integers. I've attached my little vi. I have also tried using the example method of returning void in the dll and using a pointer to an integer to get the data out, but that didn't work either. I'm wondering if it is a compiler issue (or maybe I'm exporting the function incorrectly or something), as I have called win32 dlls with no problems. Anyway, thanks for your help, Jon Download File:post-1931-1140114472.vi

Hello, I'm trying to write a dll for use in LabVIEW. So I make this simple little dll source: #include "lvdll.h"__declspec(dllexport) int AddInts(int x, int y) { int z; z = x+y; return(z);} It compiles fine (using OpenWatcom compiler) and I write a little test C app and it works correctly when called from there. However, in LabVIEW, I use the call library function node, using C calling convention and wire up i32s to the parameters, I always get 1244517 as the result. If anyone has any idea what could be going on, I would appreciate the help. This is starting to drive me nuts. Thanks a lot, Jon
