Calling and re-calling with httpservice

Here is a strange thing I ran into today. I have a program
which queries a DB through an aspx script called with httpservice.
A user clicks on a name, the query runs, and populates a form with
data from the database. The user can then edit the information and
submit the form to another script which makes changes to the DB.
That is all working except that when the user clicks on the same
name again, the old information is returned. I have verified that
the DB is being altered with the submit script. If I close the
application and reopen it and select the user again, then the
modified data is there. Is there something I am missing the
httpservice call? I've tried setting the array used for the result
data to null. I even put just a text field on the page and printed
the results of the query to it. It shows the old data too. It seems
like it's not actually running the query again like it should, but
rather taking the values from some place in memory until I close
the app and reopen it. Any ideas?
Relevant parts of my code are posted.

OK...I've figured out that it is not actually calling the
page again. I had my aspx page log an entry each time the page was
called and for some reason, even though I am using the send(), it
does not actually go out and resend the data to the page. Anyone
know why?

    Solved!

    Well, first, not all devices are doing it, at least not as bad as was just described. So, that means contrary to your statement, an OS reload and/or wipe would likely fix it.
    Second, you haven't said what version you're on so no way to know if there's an update for you or not.

  • Missed calls and placed calls are not saving in 7942 phone

    HI 
    i am facing some issue in telephone directory, in my phone missed calls and placed calls are not saving. i am using cisco call manager and 7942 phone. please help me in this issue.
    Thanks 
    Shijo

    Hi Shijo,
    Is this affecting only one 7942 IP  phone or all of them? if this is affecting all then you may try ta firmware upgrade. If this is only affecting one of them then you can compare the settings of this phone with the working ones or try setting the phone to factory defaults.

  • Click to Call and Presence Options with Sharepoint

    Hi everyone,
    What options are there for providing click to call (CTC) and presence with Sharepoint? I have the following options (and thoughts) so far.
    Deploy CUPC (Not going to happen, we're happily a Lync 2010 house but would provide CTC and unsure about presence for sharepoint)
    Deploy CUCILync (Seems overkill, but would provide CTC and presence)
    Deploy CUPS and use RCC via Lync (I keep on hearing that RCC was meant to be killed off in Lync 2010 and probably won't exist in future. Would provide CTC, unsure about presence)
    Deploy click to call widget (Would be great to avoid another desktop application. Would only provide CTC)
    Deploy Quad (Don't expect the Sharepoint guys buying in to that one...)
    Use WebDialer API (Sounds like it would provide CTC)
    Use existing JTAPI integration (This should be a given... Provides CTC and presence).
    We currently have an existing Intranet, which provides click to call abilities/phone presence information using JTAPI. A team is completing a Sharepoint proof of concept and the question has come up how they can complete click-to-call and phone presence.
    Thanks,
    Mark

    The first suggest to fix this error is to make sure that CIPC is running properly and that
    a phone is selected to use with the Click to Call application.
    This message is often presented unnecessarily when the ser invokes Click to Call but has not
    entered their username and password into Click to Call Preferences then the user is
    presented with the error "Click to Call cannot find Cisco IP Communicator.  Please ensure
    it is running or select another phone."  rather than "Click to Call is not fully
    configured."
    If you have configured the user options correctly then you need to check the Click to Call log
    files to try and diagnose the problem you're having. They are located at:
    * Windows XP - C:\Documents and Settings\[Windows User Account Name]\Application
    Data\Cisco\Click to Call\Log
    * Windows Vista - C:\Users\[Windows User Account Name]\AppData\Roaming\Cisco\Click
    to Call\Log

  • Not showing missed calls and dropping calls

    I have had a Thunderbolt for several months now and I have had a problem with missed calls not showing up and voice mail showing up with missed calls, I have talked to tech and reported  this and I received a refurbished phone and still have the same problem any know issues with this?

    Hi bbarront,
    I apologize for the delayed response and its unfortunate you are still missing calls with the replacement device.  Can you please advise if you have taken advantage of the newest Software Update? Additionally, are you advising that you don't receive a notification of a missed call and the only way you realize it is when you check your voicemail?  I look forward to hearing from you soon.
    Thank you for your involvement in our community forums,

  • Function (or BAPI, ...) to skip calls and release calls in maintenance plan

    Hi, gurus!
    We need to find a function (or BAPI, ...) in order to skip a call number in a maintenance plan.
    We need a function (or BAPI, ...) to release a call in a maintenance plan, too.
    We could use a call-transaction to IP10, but we guess there could be problems with scroll and with pop-up warning messages.
    We also thought about using IP30 but there's a problem: if there are previous calls that are not skipped, transaction IP30 releases all those previous calls and we need to skipped them.
    Thanks in advance. We really appreciate your help.
    Best regards,
    J Madariaga

    You cannot skip a call in the middle of a list of active calls - this is standard functionality.
    Can you please give more info as to why you would want to do this?

  • When I am on a call and another call come in my iPhone does not beep to notify me of the second call how can I fix this?

    Please help... when I am on a call and a second call comes in my iPhone does not beep or make any noise for that matter to notify me of the second call. Why is this happening but most important what can I do to fix this? I have missed several important calls because I have no clue the call is coming in.

    Make sure that call waiting is turned on and check with your carrier to ensure that is activated on your account.

  • Can't make FXO calls, and receiving calls has no sound

    An issue started today where I can't make or receive calls using FXO ports (POTS lines).  I tested the cable going into the FXO ports and the lines work fine making calls. 
    When I call the number of one of the FXO lines in the UC320, the SPA303 rings properly, but when picked up, there is no sound on either side.  When the SPA303 hangs up, the caller phone call ends 20 seconds later.
    When trying to dial out, there is no dial tone, and the call eventually hangs up.  I'm using very old firmware, but there were no changes made that should affect the UC320. 
    I've tried FXO Impedence Testing, but nothing happens, it just says "Test Running" and the phone number doesn't get a call. 
    My network does not have the UC320 as a firewall pointing to the internet, so the time and date is way off, but this hasn't caused any issues. 

    Hi and Welcome to the Forums!
    From your description, it sounds as if your device itself has somehow failed. My opinion is that your formal support channel is what you need to use -- via your carrier.
    Good luck!

  • 3gs locking up while on calls and after calls...

    At times (not everytime but more often than not) my 3gs locks up on me when I'm on a call, after a call, and when I try to leave a voicemail.
    Locks up as in, goes black, and no matter how many times I push the home button, or try to shut the phone off as to reset, will stay on that black screen (even if the call is still active), making it so that I can't even hang up.
    Only way I have been able to get around this is by turning the vibrate switch on and off. That seems to trigger the home screen to appear.
    Not sure what to do. Have already been to the genius bar for this once before, for which the advice they gave me didn't help (restore etc..)
    Can anyone help...?
    Thanks so much ahead of time.

    If you have a case on the phone remove it. Some cases cover the sensor that blanks the screen when you hold the phone to your ear. What you describe is a symptom of this problem.
    Thanks Lawrence.
    I do use a case, however it is a see through hard case, full body, of which the entire top of phone is covered with a very thin transparent screen protector (allowing touch to work). Would this type of case be covering the sensor as you mention above? So curious as to no longer use this type of case if so.
    Also... if anyone can advise me on whether it's best to set up as new phone or from back up (my prior question), I'd be so grateful. Am wanting to use backup (as to not lose my texts), but am a bit fearful I could be placing the original problem (frozen during calls) onto the new phone...?
