Hi, I am trying to establish a HTTP connection to a URL (eg: http://abcd:1010/my-web/clientConnection) in order to "write" an XML string and get a response back. I was able to perform "read" operation on the URL using "Datasocket Read" function. Now, I am struggling with "Datasocket Write" to send the XML String to the URL. I am getting Error 1179 after "DataSocket Write" function. Attached is the Error message and the block diagram screenshot that is causing error. I tried various "modes" available in "DataSocket Open" function. Am I missing something in terms of establishing connection to the URL? Should I use any other function (TCP/IP) instead? Any other suggestions are also welcome. Thank you. - Ashish

ALL THE BEST! - Ashish

The NI Vision is full fledge vision analysis toolkit and easy to implement. I hope it makes sense and jbelim feels motivated :thumbup: -- Ashish

QUOTE(venkatesh @ Dec 6 2007, 06:28 AM) If you are talking about "Remote PC Access", I prefer Real VNC software (you need it installed on both PC, Remote and Local). If you are talking about access of a Remote PC from LabVIEW on local PC, that is a different story. What do you want? --- Ashish

QUOTE(John Dierks @ Nov 27 2007, 07:44 PM) Welcome to the LabVIEW world! I will suggest to look for right people to work with instead of "Job Openings". It sounds more philosophical but it will help in long run! There are good resources of "NI Alliance Members" available on NI website (I do not have the link). That is good place to start. ALL THE BEST! :thumbup: Regards, Ashish

QUOTE(CraigGraham @ Nov 26 2007, 05:58 AM) I am using LabVIEW 8.2.1 for programming cFP and the only way to upgrade the VI on cFP is by building EXE and setting the EXE as "startup" before deploying. I am pretty sure that it should be possible on LV 7.1 too. Setting as "startup" and deploying will configure the cFP to run the EXE on power up. This way, you do not have to "Exit without closing RT Engine VIs". Also, cFP power reset will not matter. I am also looking around for programatically upgrading software of cFP, so that multiple cFPs can be upgraded from a PC on same network. --- Ashish

QUOTE(akala @ Nov 17 2007, 04:06 PM) The latest Device Drivers should be compatible with all the LabVIEW versions, unless specified in ReadMe file. I found that the driver installation allows you to install the drivers for more than one LabVIEW versions! Try running the Device Driver installation and you will know what I mean. --- Ashish

QUOTE(sachsm @ Nov 5 2007, 12:57 PM) I experienced problem with Property Node on RT system. But, Local Variables worked for me! I wonder if you are running any kind of "Timed" loop. Did you try running the loop slower (~500 milli sec) interval? --- Ashish

QUOTE(akjohn @ Nov 2 2007, 10:13 PM) I am using Compact Field Point cFP-2120 controller. I found that there is a file "ni-rt.txt" on the controller which contains the accurate name of the controller. So, I created a VI to parse this file and get the name. Since, you are also working on RT system, I believe the above mentioned trick will work for you too. I hope this helps. --- Ashish

QUOTE(José Sousa @ Oct 30 2007, 08:00 AM) José Sousa, I am not sure but I will suggest to start your driver search from NI Drivers and Updates (http://joule.ni.com/nidu/cds/fn/p/lang/en). I hope that helps. Ashish

QUOTE(MikaelH @ Oct 18 2007, 03:05 PM) I am pretty sure that you are aware of this. But still.... Regarding core assignment in LabVIEW, I know that in LabVIEW 8.5, the Timed Loop structures can be assigned to specific cores on the processors. --- Ashish
