Hi,

use Advanced/Call libtrary function.
1. Double click on this function.
2. In opened window you need select function
from list of functions that consist your dll.
3. Fill all function's parameters.

For using dll's in labview, just go to 'advanced' in the functions pallete
and then klik on 'call library function'
When you dubbelclick it, you can see that you can select the dll you want to
use
You can also check out the help of this function.

Hi 214552213;

There are several references at NI Developer Zone that explain how to access a dll from LabVIEW. You need to know the function prototype of the function you are calling in order to make the right call from LabVIEW. If you have LabVIEW 6, it allows you to see the different functions, but not the necessary arguments. If you have LabVIEW 5, you can use a vi available from NI<
/a> to view all the functions exported in a dll. Follow nchernin instructions...

Using External Code in LabVIEW, which you can access from LabVIEW's help or access through the link above.

If you are writing the dll, check the several articles in NI website. There is a lot of documentation, but specially for doing it using Microsoft's VC++.
