You can also use XControls for these kind of application..Attached a sample for your reference..QUOTE(karthik @ Sep 18 2007, 02:04 PM) You can use Xcontrol for these kind of application..attached a sample code that does the same..

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 QUOTE(siva @ Sep 11 2007, 12:18 PM)

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 Siva QUOTE(Kevin Boronka @ Sep 11 2007, 07:53 PM)

Use the attached ActiveX component to access images from Webcam.

Implementation of Common industrial Protocol (CIP) via EtherNet [EtherNet/IP (CIP)] EtherNet_IP_PCCC Use these set of VIs to communicate with MicroLogix Series PLCs Via EtherNet. These VIs use simple TCP/IP Communication. Communication : Ethernet, TCP/IP Protocol : EtherNet/IP Service :CIP (For Connection Management), CIP Service for PCCC Command : PCCC Tested with : MicroLogix 1100, MicroLogix 1500,1200(with NET-ENI) No OPC Server Required No Automation Server Required No NI-DSC Module Required. 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. EtherNet_IP_CIP Use these set of VIs to communicate with CompactLogix, Control Logix Series PLCs, Any Device that supports CIP(EtherNet/IP) These VIs uses simple TCP/IP Communication. Communication : Ethernet, TCP/IP Protocol : EtherNet/IP Service :CIP (For Connection Management, Read, Write) Command : CIP Commands Tested with : Compact Logix Series PLCs No OPC Server Required No Automation Server Required No NI-DSC Module Required.

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.

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.. Download File:post-4279-1168672256.zip

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. Download File:post-4279-1168671705.zip

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.
