Darnell:

Whenever you get an unexpected end-of-file found message from a compiler, the first thing to check is your block constructs to make sure you have matching {}.

In the code you posted, you have two opening braces {, but only one closing brace }.

When you're using the #ifdef __cplusplus statement, you don't typically include a whole block of code, you just wrap the extern "C" statement, and separately its closing brace.  Check the examples in the links I posted earlier to see how this is done.

As I also mentioned earlier, you don't want to declare C++ code as extern "C".  It doesn't make any sense to declare a class extern "C" as you seem to be doing.  The only things you want to extern "C" are your wrapper functions, as I suggested earlier.

im still getting the same thing now, when i  put the close braces.

and also when you just export your function, do you mean the function call or the prototypes

where to put the headerfiles, do i put them in the wrapper?

Darnell:

You're still not using  extern "C" as I described in the links I posted earlier.  Go back and look at those links.

#if is different than if() in that you need an #endif for each #if.

You have two #if's and only one #endif.  So the compiler gets to the end of the file still looking for another #endif that's not there.

Use braces to block the statements you want affected by #if.

Here is some more information on exporting functions from a Viusal Studio DLL:

http://msdn.microsoft.com/en-us/library/16ya5xae(VS.80).aspx

The wrapper functions will be defined in your CPP files.  You will export the functions (see the MSDN link above), and include the prototypes of the exported functions in a .h file that your CVI program will #include.

okay i started all over to make sure i was following what you were doing, i had to start over from scratch,

check this see if this is what you are talking about.

[darnell]

I think im almost there, i have everything you say to do, now for im getting a alot of errors pertaining to one header file

you can check the project thats in CVI that i attach

Darnell:

Please remember that this is a LabWindows/CVI forum, not a C++ forum.

I'm not sure what you would like us to do when you post a 3Meg project and say "check this see if this is what you are talking about".  Do you have a specific question?

How can I know where to start when you say "im getting a alot of errors pertaining to one header file" ?  What errors?  What header file?

Your best chance for success on this forum is if you ask a specific question about CVI.   

[darnell]

i got the c++ part right it just when i get to cvi to call the functions from c++ , i get errors, im going to post a screen shot of the erros i get thats better.

OK CHECK THE ATTACHMENTS ,I POSTED THE ERRORS IN SCREEN SHOTS, AND THEN THE C++ C FILE AND THE HEADER FILE IM GOING TO COPY AND PASTE

this is not a visual studio forum... but sometimes (often) this error is related to precompiled headers, either due to a badly formed project or a file you deleted (stdafx.h ?): turn off precompiled headers in the project options or recreate your project from scratch (or learn how precopiled headers work and correct the real problem)

Although it is in LabVIEW you may want to consider taking a look at something I created, "LabVIEW Speak"

The entire code base is open and I'm using the .NET API so perhaps you can see how I accomplish some of these actions that you're trying to work through. 

Article Posting: http://zone.ni.com/devzone/cda/pub/p/id/909 

Getting Started Videos: http://decibel.ni.com/content/groups/labview-apis/blog/2009/11/19/labview-speak--programming-lv-thro...

This program does a variety of things out of the box, but is also intended to act as an abstraction layer between the user and the Microsoft .NET speech API. 

I haven't read the whole thread, but this tool allows you to make a command set array of strings, send it to the LVSpeak Engine, and receive LV events when one of the commands is detected.
