how to change function name before building a DLL

[brock85]

I am building a image analysis software platform which will import an image online from a camera or offline from a file directory. I'm writing the software architecture in such a way that an exe file will call several image analysis DLLs to analyse the image and return data.

Image analysis DLLs will change and be added from time to time. So the DLL file must be able to be called dynamically by the exe file.

I made all the DLLs have strictly same input output type. So the exe file will read the DLL path from a text file and call the DLL accordingly.

The advantage is i don't have to recompile the exe file even i add or remove some DLL files.

Unfortunately i keep getting error from "Call Library Function Node" when it tries to call the second DLL.

Calling different DLLs dynamically without adding the DLLs in the vi, is that possible to be done in LabVIEW 2012?

Please help.....

As for the error you get:

can you post a code snapshot?

Thank you MarcoMauri, now i'm able to load dynamically any DLL into my program by just hanging a config file in txt format without compiling the exe file.

As my appreaciation, is there a way i can give a good rate to the solution you provided?

Thank you so much!!

By the way, i found out that if i'm need to check the "run in any thread" box if i want to load the DLL dynamically. Anyone knows what is the difference between "run in any thread" and "run in UI thread"?
