Wasn't sure which forum to but this in. It's both C and LabTalk.

I've built a DLL coded in VC++ (not a fitting function) as well the applicable header file. I can call functions in the DLL via Origin C.

But I can't call them directly via LabTalk unless I create an Origin C wrapper function. And yes, the functions are compiled into the workspace.

Can in fact, such functions be called directly in LT?

EDIT
===
The depends application shows that the functions are exported from the DLL. And I've also seen this post: http://www.originlab.com/forum/topic.asp?TOPIC_ID=7859 though I had already written my header file correctly before I saw that post.

But what are you going to do with nothing but a string? MOCA? Python's there, go try it!

That answers my question.

If I want to call a function in my DLL from LabTalk, for example:

double d1 = 1.23; double d2 = myfunc(d1, 0);d2=;

I have to wrap it in an Origin C function.
