There are general instructions in the shipping document called "Using External Code in LabVIEW". You can view this by going to Help>Search the LabVIEW Bookshelf. You use the Call Library Node Function and specify the parameters per the dll's .h file. LabVIEW 8.20 has a wizard that will do this for you.

Just one caveat before trying the wizard. You need the .h file that goes along with your .dll. Otherwise, the wizard won't work. Speaking from experience.

Spent the last couple of days trying to get 3rd party VC++ into a .dll (didn't work), into a format that I could use in CIN (didn't work) and Math script. (ditto ditto ditto)

I just upgraded to 8.2 so I'll use the .dll wizard!!! Didn't work. (no header file)

Eventually got everything humming along with ActiveX.

Hi Naveen,

You need to use the "Call Library Function Node " function in LabVIEW to call any external dll. With this function you can select the dll and specify the input and output parameters. Here is a link to a sample LabVIEW code that calls a User32.dll to play Window sound file.
