Re-seting "first call?" in sub VI
I am trying to use the 'first call?" thinger in a sub-VI. I thought it would re-set when the sub-VI was closed, but when it is called again, the "first call?" thing does not give me a true. Is there any way of correcting this?
The state has nothing to do with the visibility of the front panel, it will reset every time you newly start the toplevel VI.
For any given run (not subVI call!), "first call?" will be true exactly once.
If you want your case to be true every time the subVI is called, replace it with a TRUE boolean diagram constant Another option would be an initialized shift register. It really depends on the details of your code.

Error obtained while calling a sub-template in RTF.
Hi,
I am trying to call a sub-template from my RTF template using
<?import: file:///C:\Desktop\Sample RTF\TEST.xsl?>
in a form field and
<xsl:call-template name="add-X"> <xsl:value-of select="." /> </xsl:call-template> in another.
The xsl file related to this template reads as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" version="1.0">
<xsl:template name="add-X">
<xsl:param name="string" select="." />
<xsl:if test="$string">
<xsl:text>X</xsl:text>
<xsl:value-of select="substring($string, 1,1)"/>
<xsl:call-template name="add-X">
<xsl:with-param name="string"
select="substring($string, 2)" />
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
But I am ending up with an error. The error obtained is:

Why poor WCF performance for first calls?
I'm seeing some weird WCF call timings that I can't explain, and it is causing some real issues in my application. My WCF service calls seem to be taking hundreds of milliseconds if not seconds longer than they should.
I've set up a simple SL5 project hosted in a web app project just to reduce the variables, and I still see terrible timings.
I've got a very simple WCF service call, and I'm using ClientBase to instantiate the service instance, then I'm calling the service in a tight loop 30 times (asynchronously).
The problem is that the first handful of calls take extremely long, according to the IE F12 tools. I'm seeing network times of between 500ms and 2000ms. After that, all of the service call times drop down below 100 ms. The problem for me is that,
when I am just calling the service once in an application, I am seeing these initial delays, meaning every time I call the service it tends to take a really long time. I only did the tight loop test to see if things get better over time, which they do.
I would imagine it is doing something like establishing the initial channels, and that is what is taking the hit, and then calls after that just reuse them, but is there anyway to reduce that initial hit? Adding tons of extra time to each of my
calls in the real app is killing my performance.
Here is a screenshot of F12 with the call results. You can see the first bunch of calls take an extremely long time, then everything gets nice and quick after:
Here is the calling code in the test app:
Private Sub TestWcfClientBase()
Dim client = ServicesCommon.GetService()
client.Proxy.BeginGetCurrentUser((AddressOf OnGetUserCompletedCommon), Nothing)
End Sub
Public Shared Function GetService() As ServiceClient(Of IServiceAsync)
Dim service As New ServiceClient(Of IServiceAsync)("IServiceAsyncEndpoint")
Return service
End Function
Public Class ServiceClient(Of T As Class)
Inherits ClientBase(Of T)
Implements IDisposable
Private _disposed As Boolean = False
Public Sub New()
MyBase.New(GetType(T).FullName)
End Sub
Public Sub New(endpointConfigurationName As String)
MyBase.New(endpointConfigurationName)
End Sub
Public ReadOnly Property Proxy() As T
Get
Return Me.Channel
End Get
End Property
Protected Sub Dispose() Implements IDisposable.Dispose
If Me.State = CommunicationState.Faulted Then
MyBase.Abort()
Else
Try
Catch
End Try
End If
End Sub
End Class
The client config is as follows:

</system.serviceModel>Hi ChrisMikeC,
Based on your description and config file, it seems that you host your WCF Service in IIS and you try to consume this WCF Service in a SL5 project, if I do not misunderstand you, in my mind when we are hosting our WCF service in IIS, there is a high
cost for the first call. On the first call to our WCF service, IIS must compile our service. Then IIS must construct and start the service host, so it will be slow in the first call. For more information about how to improve the time for the first call, please
try to refer to
this article. Meanwhile please try to host your WCF Service in Windows Activation Services or Windows Service in where you will have greater control on the service host startup.
Besides, since your SL5 project hosted in a web app, then in my mind ASP.NET applications always takes longer in first call because it includes JIT compilation step, and ocne the code is compiled, all the calls thereafter are faster than first one, so please
try to use the Console application or a Windows Forms appliction to test if the time can be slow down.

Amy Peng

IPhone 4s call waiting; how do I get back to the first call?
When I'm on a call and a second call comes in I tap "hold current call and answer." I get connected to the second call and the first call is put on hold. But when I am done with the second call, how do I get back to the first call? I can't find any way to get back to the call that is on hold. I usually end up hanging up on both calls. Not good.
Also, how do I switch back and forth between two calls? How do I put the second call on hold, go back to the first call to tell that person I must call them back, then return to the second call?http://support.apple.com/kb/TA38607?viewlocale=en_US

In Test Stand when I call a sub-VI front panel, the pop-up window goes behind all the windows and the user just waits for the screen. I want the pop-up to come to the front so that the user can know what to do. I couldn't find any property that I can set which would make the called VI go to the front.
What version of TestStand are you using? Here are the TestStand palettes in LabVIEW for TestStand 2.0 and 3.1. You can also set a VI to be modal in VI Properties>Window Appearance. Select Dialog or go to Cutomize and change the Window Behavior.

Yes- stop invoking an object that is disconnected from its clients. This will get rid of your "error"
Of course, that means nothing to anything that is not a 'Windows OS'.....
Please - post the offending code so we can analize the code and not the"error" messagases Hmmmm

Hi Guys,
I'm experiencing a problem with CoCreateInstance, where it returns error 0x8007007e.
The code is something like this:
HRESULT hRes = S_OK;
CComPtr<IMyInterface> spObj;
if(FAILED(CoInitialize(NULL))) { /* quit */ }while(FAILED(hRes = spObj.CoCreateInstance(CLDIS_MyClass, NULL, CLSCTX_LOCAL_SERVER)))
// LogFailure(hRes);
Sleep(10);
The problems occurs only on a single machine having Windows 2008 Enterprise SP2 installed (it works fine on other machines / OS versions). It happens only during the system startup (this is a Windows Service) and only for the first call of the CoCreateInstance.
The second call always succeeds.
The problem does not occurr when starting the service manually from Services.
I did some investigation using Process Monitor and found that the HKCR\CLSID\[CLSID of MyClass]\LocalServer32!LocalServer32 registry value is accessed before the failure. The registry value exists - it is added by the Windows Installer during
installation.
If I remove the registry value then the CoCreateInstance always succeeds.
I've been trying to lookup for some documentation on HKCR\CLSID\...\LocalServer32!LocalServer32 but haven't found anything useful other than it's a "Windows Installer Entrypoint". I assume that the Windows Installer does some integrity checks when
calling CoCreateInstance for such class and this fails for some reason but currently I fail to find the reason.
Can anyone help finding out what's the root cause of the 0x8007007e error here, please? Any help or tip is much appreciated.
Many thanks!

How to quickly pick up a 2nd call and drop the first call
If I am on a phone call, and then a second call comes in, then how can I quickly pick up the second call and DROP the first call? I can do it if I put the first call on hold but then I have two calls going. If I simply END the first call, then it takes 5 or 6 seconds for the second call to come in. Several times I have lost the second call because it took too long to transition over.
never mind i did a direct chat with a skype rep and got my answer which is no.

Verizon's iPhone 4S is dropping the first call almost all the time?
Hi.
I have a verizon iPhone 4S.
Everytime I make the first call to someone, I don't hear anything.
When I end that call and try calling again, it works.
This has been happening almost all the time.
I tried letting the phone app turned on but it doesn't solve the problem.
I'm not sure if other carrier's iPhones are having this problem.
Does anyone know what the problem is to this?
Thank you very much.I tried letting the phone app turned on but it doesn't solve the problem.
What does that mean?
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
If still a problem, restore.
If still a problem, take it in to Apple for a warranty replacement.
IMO, you'll probably end up taking it in to Apple but the other steps are worth trying. -
Skype Windows client hangs for the first call - co...
Hi,
Skype on my Windows 8.1 (depending on its mood) hangs for the first call. It will keep ringing and ringing till it times out, during that time I am not able to hang up the call as well, the red hang up button doesnt work and we have to let the call go on till it drops on its own. Then on the second try it connects perfectly fine. This happens most of the times, there are only a few days where it connects on the first try otherwise its always the 2nd time.
Please let me know what could be the possible solution for this one?

Cannot pick up calls on wait, Cannot make a second call holding the first call
I have a really weird problem with my iPhone 5S. (iOS 7.1)
1. When I am on a call, I am not able to pick up a second call that is on wait. I can see the second call, I can hear the beep sounds but as soon as I pick up, the call freezes in 00.00 time, and My first caller is still active, not on hold.
2. When I am on a call, I am not able to make a second call placing the first call on hold. The second call disconnects immediately with 3 beeps.
3. I am able to see the incoming calls on wait, when I am already on a call. I am able to hear the beeps coming in. SO it means the call waiting is on (Tried turning it on/off/on too.) But when I pick up the call, the above problem comes in.
What have I tried to solve this: (None of them helped)
1. I tried a hard reset of my iPhone (Holding Power and Home button)
2. I tried toggling the Call waiting button
3. I tried resetting network settings.
4. I called my Operator for assistance. I am using Airtel, India. They told me to dial this code - *43# . I tried it and it gave me this screen. But the problem is not solved yet.
Is there anybody here who is facing the same issue with your iPhone? I never had this problem with my iPhone 4.Make sure you do not have "Do Not Disturb" turned on. This feature will block the first call, but is someone calls right back it will be put through.
On the iPhone, go to Settings/Do Not Disturb
Make sure you do not have Do Not Disturb turned on manual or scheduled. -
CME - Second Call Drop the first call
Greetings,
Anyone ever seen something like this?
I get a call on my extension, and when I receive a call on another phone, the first call (in my Phone) drops.I'm seeing this also with IPC softphone version 8.6.
Has anyone resolved this issue? -
When receiving an call waiting can't push the hold and answer button.Because: it will put on hold the first caller, answer to the second, but you can't hear the second until you end the first call !!! Anyone has the same problem ? Did anyone know why ?

The ATA only rings the first call
HelloI've just had instaled an ATA Linksys SPA2102 conecting it to a DSL modem CTC UNION model ATU-R130. The SIP is INPHONEX.COM
My ISP had to redirect some ports to a fixed IP address in order to make the ATA RING.
I make a call to the number assigned to the ATA and it rings ok the first call (many rings but only the first call).
After that I make as many calls as I can, but the ATA doesn't detect that a call is going on. Then I must reset the ata with the factory default values and re-enter all the SIP information in order to get the ATA ringing again.The ATA works fine making calls. The problem is receiving them.Does somebody know what's wrong?
Thanks
JuanOn your next attempt on calling the ATA , try checking the Info page under the Voice tab then look for Hook State, you may want to check first if the ATA disconnected the last call properly. Try checking also if you're using the latest firmware on the unit.
