I'm trying to communicate with an external .dll but the necessary header files are absent. I saw an earlier post in this vein, and obtained extcode.h from it, but everything that it calls is also missing. The earlier suggestion about a custom installation of the toolbox has also proved ineffectual, since it doesn't seem to be extant at all.
The CD is marked "Base Package for Windows 2000/NT/Me/9x" so I bet that's the problem. Now to go talk someone into springing for the professional version...
Although now I do have to wonder why in the "examples" folder there is a "dll" folder with sample VI's that use external code. And what's more, they work. Oh, well. Thanks!
