Well, considering the functionality you implement it would be about 1000% easier to implement that directly in LabVIEW. This is in fact a statement that is true for many programming problems although the amount of advantage you get will vary a bit.
If you insist on using your C file approach you will have to find a C compiler that can create a DLL from that C file. This will likely require you to study a bit about DLLs and how to create them in your C compiler. And then some more studies about how to call a DLL from LabVIEW using the Call Library Node.
But implementation of C code to be used in LabVIEW has only two really good reasons.
1) If you already have the entire C code available and want to reuse it as library in LabVIEW. Rewriting everything in LabVIEW is in that case often not a feasable option.
2) If you need to do low level stuff like calling into system APIs, calling device drivers, or doing general low level stuff that requires a lot of bit shuffling such as compression/decompression or encryption/decryption algorithmes.

hi, how do i call java files from a different directory??
let say i got partA.java, and i need to include functions from partB.java which is in a different folder. how can i do that?

Hi nuttynibbles,
Before the class declaration in partA.java, you must have an import statement like :
import someDirectory.partB;
public class partA {
... and before you ask... you'll probably want to read through this http://java.sun.com/docs/books/tutorial/java/package/index.html

How to call class file from jsp without creating packages

i m using tomcat 5.5
i stored my class file into WEB-INF\Class directory
how to call that class file. from my jsp page.
i got some error.
i used package concept,that works fine.Then use packages.
As of Java1.4, you can no longer import classes from the default package (no package declared) into classes that are packaged.
All Tomcat classes are in packages, including the compiled JSP.
Therefore: Your classes need to be in a package inorder to be imported and used by the JSP.
Why the problem? If you know it works with packages, why try not to use them?

How to call javascript file in windows?

I developed javascript for automated pdf files. But i don't know how to call that javascript file from outside of acrobat. Kindly advice me the various way to use that script. This is for acrobat 8.0.

You can place Acrobat JavaScripts in various form elements, document actions, documents, and the application folder or user application folder. See the Acrobat JavaScript API Reference and Guide fo rmore information, http://www.adobe.com/devnet/acrobat/javascript.html .
From within Acrobat's JavaScript's debugging console, one can use the following code to locate the JavaScript folders used by Acrobat/Reader:
function JSInfo() {
/* define function to report JS information */
// some basic system information
console.println(app.viewerType + ' ' + app.viewerVersion + ' is running on ' + app.platform);
// user level script folder
try {
var userJS = 'User level JS folder: ' + app.getPath("user","javascript");
} catch(e) {
var userJS = "User has not defined use JS folder level scripts";
console.println(userJS);
// application level script folder
try {
var appJS = 'Application level JS folder: ' + app.getPath("app","javascript");
} catch(e) {
var appJS = "There are no defined application level JS folder level scripts";
console.println(appJS);
return;
} // end of JSInfo function
JSInfo(); // call the function

How to call java file when entering the another jsp page.

when i click the link to link to another page, when enter the page, how can i call java file and passing id parameter to call method, which is connected to DB.
when enter the page, how can i call java file together with one arguement???

I would strongly suggest to go the MVC way. Please perform all DB operations through a Servlet/Action instead of directly hitting the JSP and then invoking a java bean to do the DB operation. JSP should only do the rendering.

How to call swf file within another swf file using xml

This is the AS3 forum and your posting involves AS2 code. You should repost in the AS2 forum...
http://forums.adobe.com/community/flash/flash_actionscript
Aside from that, your problem might lie in the following lines...
_root.createEmptyMovieClip("sub_container1", 1);
loadMovie(sub_SWFPath[1].attributes.url, "sub_container1");
You create the new movieclip, sub_container1, in the _root, but you do not assign the loadMovie to load into that same movieclip (unless you have a _lockroot = true assigned in your sub-swf). In any case, you should repost in the AS2 forum to pursue resolution.

How to Call .XDO file From Java Program

Hi,
I have developed a report in using BI Publisher version 10.1.3.
I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
What are the APIs available to do that.
Thanks
-Ashutosh

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

How to call exe file as a link in oracle portal

I have an executable file (.exe) that I would like to call as a link from portal. I've uploaded the file and can click it and the executable runs. However, I'd now like to be able to pass a URL as a parameter to the executable file and still have the executable run. Any ideas on how I can accomplish this?

No.
However I might try writing a PHP page and use shell_exec inside to pull it off.
http://www.chipmunkninja.com/Program-Execution-in-PHP%3A-exec-m@
You could link or redirect from the portal to the php page and even have the php send you back to the portal.
