Using timeout with oci_execute

Hello everyone,
is there any way to specify a timeout when executing query with oci_execute? We'd like to be able to limit the execution time. Sometimes, it's better to kill the query and tell the user the query has failed, instead of letting it run wild and eventually overload the whole system, when the user starts hitting reload in his browser.
I know there is OCIBreak() ic C that can be used together with a background timer, but I do not know about any solution in PHP to handle this.
Thanks for any ideas,
Michal

How to avoid the page timeout with the HP Color LaserJet Enterprise CP4025?

We are using a DOS application developed with DB4 and running always on the same XP workstation. One month ago we changed our previous HP color printer (was broken) buying a newest CP4025. With the previous HP color printer, and also with another printer we have (HP Color LaserJet CP2025), our application works very well. But using the CP4025 now we have a problem.
When our application prints in PCL mode, sends the first part of job, then the application perform some calculation tasks with the database and sends the final part after about 30 seconds. We don't know why, but the CP4025 seems to have a timeout after about 15 seconds that cause closing the printing job with a sort of end of page, printing wrongly a half page, and after a new page with the second half of the real single page.
Why the CP4025 have a so short timeout? Our previous HP and also the CP2025 works well with our application, without perform any kind of short timeout.
Anybody knows how is it possible to avoid this timeout with the CP4025?

In theory PCL5 jobs should only be terminated and forced to finish printing via either an IO timeout, the network connection being closed, or an end of job command in PCL5.
You can check/change the default IO timeout value through the front screen. You'll find it by navigating to Configure Device->I/O->I/O Timeout. I would recommend making sure it is set to something around 120 seconds.
Do you know whether the application itself is generating the PCL5 job, or whether it is going through a print driver to generate the job?

'Using ColdFusion with Flex – sample does not work

Hi, I am having problems with Tom Jordahl's article on 'Using
ColdFusion with Flex – Part 1: Creating and running a contact
manager application' found on link '
http://www.adobe.com/devnet/flex/articles/coldfusionflex_part1_02.html'
I do not understand his instruction. In step 4, it states:
"Copy the channel definition from the example Flex
configuration files found in resources/config (default location:
C:\fds2\resources\config\). "
In that folder, I have the following files:
data-management-config.xml, messaging-config.xml, proxy-config.xml,
remoting-config.xml. So which file in this folder am I supposed to
copy from. And where am I supposed to paste it to? Is it into
WEB-INF/services-config.xml file ?
When I ran the test,
http://localhost:8700/samples/dataservice/cfcontact/contactmgr.mxml,
I get the following errors:
4 Errors found.
Error /dataservice/cfcontact/contactmgr.mxml:31
Definition samples.contact could not be found.
30: import mx.rpc.events.*;
31: import samples.contact.*;
32:
I am very new at Flex and trying hard to understand this sw.
Can someone pse help. Thanks a million.

What he means is to copy the channel section from the

LCP Timeout with server 10.8.2 VPN

Does anyone else have a problem with VPN on a Mac Mini... I will intermittently receive LCP timeouts when trying to connect using PPTP... I can connect Using L2TP with no problems at all. Any thoughts?
-Jim

Hi Guys,
OK.. I seem to have it working like it should now... no problems logging in PPTP or L2TP... Problem is I don't know how I fixed it. :-0. ( I haven't had time to research it)
the only thing I did was go back to the router and reconfigure the following port s and settings.
Port Forwards on the 2wire Modem/Router.
Port 500 (UDP)
Port 1701 (UDP) (for L2TP)
Port 1723 (TCP) (for (PPTP)
Port 4500 ( I used two definitions one for UDP and one for TCP on the same port.)
I have a suspicion that You may need to do this when working with "Winders" machines NOt sure though. Like I said I haven't had time to piddle with it since it's working.
I do know that every thing has to be just right for VPN to work correctly. Also check this handy link or Mac port usage. http://support.apple.com/kb/TS1629

HT202667 Hi - My daughter was using her Apple TV until recently when she got a Smart TV. Now the Apple TV is not needed so she passed it on to me. How do I get it transferred over from her Home Sharing account to mine so that I can use it with my PC?

As Winston Churchill wrote, however you might want to do a factory reset on the Apple TV.
This way all information pertaining to your daughter will be removed from the device. Specifically if see was sign into any of the streaming service, Netflix, Hulu, etc. her credentials will still be associated with this Apple TV, doing a factory reset will remove all that and make it as if you purchased the device and just plugged it in.

OPEN CURSOR using a WITH clause in the select query

Hi,
I am using Oracle 9i. I have a requirement where I have a REFCURSOR as an OUT parameter for my procedure. I have declared the TYPE and created the procedure.
In the procedure, I am using OPEN <cursor_name> FOR <query>;
Ideally this works in most of the cases that I have tried earlier. However, in the current case I am using a WITH clause in my query to get the results.
I need help in understanding if the above mentioned syntax would not allow me to use the WITH clause in the query.

What error do you get , seems to work ok for me on 10g

I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way? I appreciate that it is a different computer but I am now the end user of both devices and I was just wondering if it was possible.
Thanks,
Sean

The answer would be in your software license agreement for Aperture. However if you cannot locate it you can ask in the Aperture forum, the link for that is:
https://discussions.apple.com/community/professional_applications/aperture
However I believe you can have Aperture installed on two machines however only one may be using it at a time.
On the new iMac launch the Mac App Store - Purchased - look for Aperture and download to your new machine.

How do I use user_datastore with a feeder proc to add an mdata section?

Hi,
I have text data spread across a number of different tables. I have created a user_datastore with a feeder procedure that creates an xml document which is then indexed into a dummy column on the parent table. This works fine. However I need to add an mdata section to the index, via my xml document. I haven't seen any examples of this being done in conjunction with the ctxsys.auto_section_group option of the create index statement, and am wondering if it is possible?
Could somebody furnish me an example of how I achieve this.
Oracle 11.2.
Thanks
Ralph

You can't use MDATA with AUTO_SECTION_GROUP. AUTO means it automatically assigns zone sections for every tag it finds - if you want anything other than zone sections you must use BASIC_SECTION_GROUP, XML_SECTION_GROUP or HTML_SECTION_GROUP and manually define your sections.

Using Excel with Visual C++ 6.0 (need a graph control that behaves as much like the one in CVI as possible)

I hate to beat this to death but I was unable to find a
clear answer to this question. Does NI provide Excel control from within
Visual C++ 6.0?
I read that NI supports the ANSI-C library only for Visual C++ 6.0 users:
Thread : "Re: Benifits of using measurment
studio for VC++ 6.0?"
NI REP : drohacek
Quote : "we made the decision to support Visual
C++ 6.0 users only through the ANSI-C interface and not through the Measurement
Studio MFC-based class libraries."
If there is a suggested way of controlling Excel from within Measurement Studio
for Visual C++ 6.0 then I’d love to know it.
If not, can a plain statement be made basically stating that if you want
to control Excel you can’t use a Visual C++ 6.0 environment even with Measurement
Studio support?
With .NET of course you can just decide to have Excel support added during
project creation. CVI can act as an ActiveX server and easily control
Excel just by building off the examples shipped with CVI. I see that
there is support, using the Measurement Studio for Visual C++ 6.0 Project Wizard,
for taking existing CVI projects and converting them to Visual C++ 6.0 projects
or for calling CVI libraries from a .dll from within Visual C++ 6.0. I suppose I could do the work
in CVI and then convert the project but I'm so deeply tied into all my MFC calls that I don't see
how I can cleanly include the CVI libraries into my existing VC++ 6.0 projects.
What I'm really after here is a visual graph control like the one in CVI that I
can use from Visual C++ 6.0. I purchased a 3rd party graph control for use
in VC++ 6.0 that works well but isn't really visual. I mean you can't
enter any values in it until you run the program and fill it out programmatically.
Then you can see which columns are two narrow, quit the program, adjust the
column width of your now empty control, and repeat, until you get the thing
looking the way you want. If I could call into Excel from within Visual
C++ 6.0 the way I do from within .NET
then I could use Excel to hold the table and just read in the values into my table
control at run time. Basically I'd use Excel as a visual development tool
for all my tables.
I do all my coding from within CVI and Measurement Studio for Visual C++
6.0. I'd use CVI for everything if I didn't depend so heavily on certain
outside controlled C++ .dll's. Could you please suggest then what I can
do to get Excel support for Visual C++ 6.0?
Last question :
Is there any plan to ever have a NI table control like the CVI table control for
use in Visual Studio? One that you can
completely set up before you do any compiling?
I imagine that the way Microsoft sets up their environment makes this idea impossible. Otherwise someone would
have come up with a truly “visual” table control before now.

Hello Grant
You can most certainly use Excel with VC++ 6.0. Measurement Studio won't provided you with any classes to talk to Excel in VC++ 6.0. This is because Excel allows control via Automation and you can use its automation API to do anything you need with Excel. This is what CVI uses as well.
You can see this MSDN article on how to set this up. This mentions VC.NET, but it should work the same way.
Here is one that talks about VC 6.0 and Excel.
Here is a code project article about this.
Even with .NET, you have to do thru the Excel Automation support. Excel started shipping with Primary Interop Assemblies (PIA) which are .NET wrappers about the Excel Automation object model. C++ Automation is definetely not as nice as .NET, BTW
See this document for more information about the Excel object model.
I would not recommend using the CVI Excel libraries if all you want to use them for is Excel automation. You will end up creating un-necessary dependencies and go through extra layers that way. You can make calls straight to Excel from VC++ without requiring CVI.
One quick observation about your excel approach. If you decide to use Excel as your table, you might be requiring everyone who uses your application to have Excel installed on their machines. Just wanted to make sure this was acceptable to you.
Have you looked at the Datagrid Activex control, which is one of the common controls that ships with Visual Studio? You can add it to Visual Studio by right-clicking and picking it from the list of installed activex control. If you have not already, you should check it out.
Microsoft has made significant improvements in the number of controls they provide with .NET. They have a Datagrid control that seems to be what you need.
Measurement Studio did add some high level classes for Excel and Word Automation that simplify some common tasks, but these exists for VS 2003 C++ and VS 2005 C++, not for VC 6.0. Underneath, we end up using the same Excel automation classes, so you can easily setup something similar for VC 6.0. Plus you can find alot of references online on how to use the Excel Automation object model with C++.
We currently have no plans in Measurement Studio to create a table control unfortunately. I am assuming when you said graph, you actually meant table, since Measurement Studio already provides a ActiveX graph controls for VC++ 6.0 that is very similar to the CVI graph.
On a side note, VC++ 6.0 is really really old. Have you considered upgrading?
To summarize
- Yes, you can use Excel with Vc++ 6.0 without mstudio.
- Try using the Datagrid Activex control if you just need a table.
- Measurement Studio provides high-level excel and word classes for VC++ 6.0
- Measurement Studio provides a graph control for VC++ 6.0 which is very similar to the CVI graph.
- Measuremnt Studio does not have a table control.
- VC++ 6.0 is really really old. Have you considered upgrading?

How to trigger New page while using ALV with classes/oops?

Hi All
I am trying to print a report which has to show the data in two pages.
I am using ALV with classes/oops.
Though I am able to print the report but a new page is not coming. Whole of the data is coming in one single page.
Please tell me as to how to trigger a NEW PAGE while using ALV with classes/oops.
Please send some code samples also if available.
Thanks in advance.
Jerry

using sort option you can do it. in case of grid/oo alv class ALV you can view that only in print mode/preview mode.
in case of list you can view that directly.
sort-fieldname = 'FIELDNAME'.
sort-group = '*' "triggers new page
sort-up = 'X'.
append sort to it_sort.
