I am Sorry for uploading some VIs with password protection in previous posts and for having very bad documentation..
I've removed some junk code in the VIs and now i've attached the unlocked VIs.
Thanks and Regards
Siva

Implementation of Common industrial Protocol (CIP) via EtherNet [EtherNet/IP (CIP)]Use these set of VIs to communicate with MicroLogix Series PLCs Via EtherNet.
These VIs use simple TCP/IP Communication.
Communication : Ethernet, TCP/IP
Service :CIP (For Connection Management), CIP Service for PCCC
Tested with : MicroLogix 1100, MicroLogix 1500,1200(with NET-ENI)

Sure..
Attached the Unlocked VIs.
I would appreciate, if somebody updates the code as per guidelines and makes it available free to all.
Thanks and Regards

Note: These VIs access N7 Integer File. To access other Files in the PLCs, just replace the "Fileno" Constant(0x07) with a Control and make it as a parameter to the SubVI.

Can a LabVIEW Program generate a LabVIEW Code.. ?
Is it possible to do the following in labview,
#include <stdio.h>
{
FILE myCodeFile;
myCodeFile=fopen("GeneratedCode.c")
fprintf("#include<stdio.h>");
fprintf("#include<math.h>");
fprintf("main(){int a;a=sin(1.2);printf(""%f"",a); }");
fclose(myCodeFile)
}
Note : The Ouput has to be a LabVIEW code, not a C Code.

I'm a new labview user that currently working on a project which using webcam for online machine monitoring .i'm using labview 7.0 I had successfully installed the NI-IMAQ for USB camera.I have run through the guideline in the readme file but i can't get any image. What i can c in my image output is nothing but gray with the image name. Am i missing any step? Can someone kindly provieds some guidelines on this?
Attached a ActiveX Control that can be used for acquiring images from webcam..
1) Copy the WebCam.ocx to system32 folder
2) register the Control by executing the following in command prompt, c:\windows\system32>regsvr32 WebCam.ocx
3) Now Insert the activeX Control in ur Front Panel..it would be available by the name, "WebCam.LiveWindow"
After inserting, we will be getting Live Images from WebCam..
If you want a image to store into a bmp file, then use CopyImagetoFileBMP method available in the controls..

A very important distinction - thanks!
Guys, the problem was sorted out by applying the patches released by NI Support..
Attached the patch..
Please do the following to resolve the problem.
To solve this problem replace the dir.mnu file located at:
C:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\addons\database directory with the one attached. This will also solve the garbled context help.

The "Database Varient to data" Function available in Database Connectivity addons is not working with LabVIEW 8.2.0. Contact ur nearby NI Support to get the patch.
