Question about running a test in a network things.

Hello

How do you do when you need to run/debug things connected to the network. It is only by connecting a device or use the Simulator?

Fredrik

The Simulator must make use of the network connection on the computer that is running the VMWare image. You will not see a network icon, however since it is not actually connected to a cellular network or WiFi.

Questions about running the XP on Vista Games

I've been curious about using older games of XP on Vista and have not been able to find clear answers to this topic with my own research on the internet. I'm a Fan of First Person Shooter, and they are scarce since Vista came out. So I would like to add a few shooters of Vista I have with some of the older games, but I have questions to do.

My questions are:

1. If I have an old XP game that is listed as not compatible with Vista can still use it if I play it in compatibility mode for XP SP2? (The game's FEAR)

2. This will mess up my system Vista SP1?

3. If I install 2 or 3 of these old games XP on my Vista SP1 pc and run in XP SP2 compatibility mode microsoft at some point let me no update Vista again?

4. should I patch older XP games so I don't want? I just want to play on solo not online.

(The games are FEAR, DOOM3, QUAKE4 and PREY). Everything for one player only.

I had these issues since I got Vista. I couldn't really find that responses indicated clearly by someone I thought I knew what they were talking about so I hope that I can help.

Thank you
Jebidia

Hello Jebidia,

Thank you for posting. You have very valid questions and I have some answers. I currently play FEAR (tested prey in the past) on my Vista Ultimate 64-bit without problems no matter what. I'd say you do a regular install of the games and they should work fine. Now if you have some problems, and then reinstall the game in compatibility mode. As for your other questions, you should have no worries about the game, do not let you Vista update. Patch games can sometimes resolve known problems that the games themselves are with compatiblities hardware Vista and possible. You can search for Tweakguides to find a site very useful for players.

So go and FPS in your heart happy my friend. Zack

Equium P200D - Question about running out of space on the HARD disk

First of all, let me say that I am a Silver Surfer and don't know much about how works laptop or where it stores information!
I don't am not in the least HI - TEC so please be gentle with me.

I use an older Equium P200d for 1 year with two 40 GB hard drives each.
My C drive has only 2 GB of memory left available while my E drive still has 30 GB.

I have only 3.7 GB of programs loaded (according to the research of control panel) and I know that I have 4 GB of music.

My query is - where is the other 30 GB missing?

I made the Scandisc option and deleted all the stuff from there and a defragmentation procedure.

Y at - it searches I can run to find junk I have more need?

Any advice you can offer would be appreciated.

Hey Buddy

If you are using Vista, then you should consider that Vista creates an additional partition on the HARD drive.
It s hidden and it contains backup files in order to repair the operating system if something goes wrong.

In addition HARD drive must also contain HARD drive recovery files (image).
These files are required to recover the laptop HARD drive.

So the hidden partition and the recovery of HARD drive that could be the main reason why you noticed smaller amount of space available on the HARD disk

Questions about the extension of my wireless network

I have an active Airport Extreme router and work well, but in some parts of the House, the signal is not strong and television puts buffering all the time (every five minutes).

So I bought a second thought extreme airport to expand my network. But I do not seem that it is correctly configured.

Can you please help?

(1) if BOTH routers be separately connected to the internet? or the other should be wireless talk to first?

(2) must have both routers have the same name or different names?

(3) if they have different names, we will see the two networks as we move into the House? The connected device (phone for example) will have to switch from one to the other networks?

Thank you

Joyce

(1) if BOTH routers be separately connected to the internet? or the other should be wireless talk to first?

Certainly the second... it is connected by wireless and extends wireless... That is to say there is no ethernet... However, you can make another type of configuration... Please tell us if there is ethernet available where you want the second AE located.

(2) must have both routers have the same name or different names?

They have names... but even wireless name different base station.

(3) if they have different names, we will see the two networks as we move into the House? The connected device (phone for example) will have to switch from one to the other networks?

When you extend wireless that they use the same name and you will not even know what unit you are connected to.

Try again install... reset factory EI and place it in the same room as the main AE... and to run the installer... It should pretty well automagically select wireless configuration expand properly.

Place then the second AE where it becomes the first good signal, but can still extend that to your dark area... wireless wise.

Please post again if you try to do it with ethernet between the main and the secondary airport.

Question about running a filter on the service of the Complutense University of MADRID

OK so I started almost in front of the finish line which understand me is: /. Uh, I tried to learn how to use filters and I met an obstacle that confuses me. OK, so I wrote a filter to just add "This is a test" to xComments, it is a simple test to prove a point before I push forward with a request. If everything seems to be set up, made the file (compiled without any problem) class, the component and changed the .hda to point to the class file (I think); However, I get the error message "the content item was not verified successfully. Impossible to filter "filterFile' of type 'validateStandard '. java.lang.NoClassDefFoundError: filter/filterFile: filterFile (fake name filter/filterFile). »
Here is the information about the filter
Path of the class:.../custom/filterFile/classes/filterFile.class
HDA file:
classpath = $COMPONENT_DIR/classes
Filters @ResultSet
4
type
location
parameter
loadOrder
validateStandard
filterFile
null
1
@end
It seems that the filter cannot find class file, even though I said classpath is "$COMPONENT_DIR/classes" and put the location as "filterFile.

Try to open your component in the component wizard.

There are two things that you need to configure:

(1) according to Build - build settings you should have defined an entry of the type Component class or Classes that will connect the additional component or directory linking to .jar (if your classes are packaged in a jar)

(2) pursuant to Build - build settings - advanced should have defined the path of custom class

From what you write, I guess 2) is (classpath =... in the name of the component.hda), but 1) might be gone (it is stored in manifest.hda)

If these two work, check the package name and the name of the class. Note that you need both in your definition - package_name.filter_class_name

In fact, it is not related to filters as with the use of Java custom in a custom component.

If you think that you have done everything, but it still does not work, create a hello_world as a component which will print classpath for you, as it is visible from your JVM, for example by: String classpath = System.getProperty ("java.class.path"); and then, if your device classes are really there.

Question about running from two cameras at the same time with MAX

Hello

I have two cameras attached to NI PCIe-1430 frame grabber card (Atmel Aviiva M2 CL and Fairchild 2 K LS) IRLS. It's ok when I run two cameras individually, but I can't run them at the same time.

This is the step that simultaneously run two device:

1. open MAX, select the port and start image acquisition by pressing the 'Grab' button, I can see the image at this point.

2. open another MAX session, select the other port and press "enter". I got following error:

"Error 0xBFF60021".

Unable to perform request; acquisition in progress'

Sometimes, I got this error too:

"Error 0xBFF60022".

A timeout error occurred while you wait for the specified event. If you expect a picture, check the video data is acquired in the period. If in the meantime the signal, check that the assertion of signal has occurred within the period. »

I already give enough timeout Fame to the tab settings of Acquisition.

The MAX version used is 4.5.

You have an idea on that? Makes simultaneous Imaging MAX support?

Thank you

Question about running in Acrobat under Windows

Hi all
I have an automated process that runs an application on a Windows 7 system where it is the reading of a database, gets the drawing file, opens with a control ActiveX, then print it using the Adobe Acrobat installed on this system.
There are concerns that I need to resolve as a result of this type of license?
Thank you
Bob

Definitely Yes. Acrobat is a single user product, and it must do work came from or controlled manually by the user, does not work for users or computers. Using the Acrobat server is usually held at no.

XP: Networking, Mail & onlinehttp://social.answers.microsoft.com/Forums/en-US/xpnetwork/threads Bruce Hagen MS - MVP [Mail]

I have a Photosmart C7280 and s question about a decision of the network.

I currently have two workstations connected to a router via ethernet cables. They are connected to a single (not HP) printer with USB cable through a USB switch. Two laptops to connect to the wireless router. I could replicate the existing configuration with the C7280, but the idea of a network in which the laptops were allowed to participate is very attractive. One of the laptop is running Windows version 7, the other computers running Linux. If I go for an ethernet network, the laptops will be able to connect to the printer via the router? If I go for a wireless network, desktop computers will be able to connect to the printer via their ethernet cables? A couple of Wireless USB adapters are a possibility.

I understand that you have questions about networking with your printer.

Yes, wired network connections will be no problem to connect to a wifi connected printer. Most routers bridge cable and wireless to work as a single network. There are some routers between wired and wireless networks, but these are before any company grade routers and network equipment.

A wired desktop computer will be able to print to a wireless printer as long as it is connected via the same router. Conversely, a wireless computer can print to a printer connected Ethernet as long as it's the same router.

I recommend using a network for the printer configuration, if possible, to avoid printing problems. USB hubs have been known to cause printing problems, although this isn't always the case.

Question about OWA scripts - how much time do need to run or not at all

Just a question about OWA on Exchange 2010 scripts. I have a site and unique Exchange Server. I noticed that we have a powershell script scheduled in the Task Scheduler running daily that defines all the mailbox OWA strategy. This policy is defined in the EMC access client/organizational Configuration (EMC) tab.

My question is... If the policy is already configured in the access client/organizational Configuration tab, should this powershell script run at all? Not all new users get this strategy by default (since we have only one policy OWA) If you enable Outlook Web access on the mailbox of the user in the appearance of the mailbox tab? My thought is that the powershell script and the calendar was just a postponement of the old Exchange 2003 for strategies for the OWA...

Thank you.

Questions about discussions...

Hello

I have a new app to do that requires network access.

I have read this EXCELLENT post from peter_strange:

http://supportforums.BlackBerry.com/T5/Java-development/connecting-your-BlackBerry-http-and-socket-c...

Because I can't use BIS - B because I'm not a partner of the Alliance, I wanted to take a look at the new OS 5.0 network API and see how it works.

I know that network connections should be performed in a separate thread.

I'm far from being an experienced Blackberry developer... so I have a few questions about discussions. I looked around the Internet, read on the forum, read the documentation, did some tests and so far, I came up with this code:

SerializableAttribute public class HTTPConnection extends UiApplication {}
Public Shared Sub main (String [] args) {}
HTTPConnection PAP = new HTTPConnection();
theApp.enterEventDispatcher ();
}

public HTTPConnection() {}
pushScreen (new HTTPConnectionScreen());
}
}

class HTTPConnectionScreen extends form {}
public HTTPConnectionScreen() {}
setTitle ("HTTPConnection");
Add (new RichTextField ("choose a type of connection :"));

final RadioButtonGroup = new RadioButtonGroup() rbGroup;
RadioButtonField radioButtonF1 = new RadioButtonField ("Direct TCP", rbGroup, false);
RadioButtonField radioButtonF2 = new RadioButtonField ("WAP 1.0/1.1", rbGroup, false);
RadioButtonField radioButtonF3 = new RadioButtonField ("WAP 2.0", rbGroup, false);
RadioButtonField radioButtonF4 is new RadioButtonField ("BES/MDS", rbGroup, false);.
RadioButtonField radioButtonF5 = new RadioButtonField ("BIS-B", rbGroup, false);
RadioButtonField radioButtonF6 = new RadioButtonField ("WiFi", rbGroup, false);
Add (radioButtonF1); Add (radioButtonF2); Add (radioButtonF3); Add (radioButtonF4); Add (radioButtonF5); Add (radioButtonF6);

FieldChangeListener listener = new FieldChangeListener() {}
' Public Sub fieldChanged (field field, int context) {}
ConnectionThread ct = new ConnectionThread (rbGroup.getSelectedIndex () + 1);
CT. Start();
}
};

ButtonField buttonField = new ButtonField ("Connect", ButtonField.CONSUME_CLICK);
buttonField.setChangeListener (listener);
Add (buttonField);
}

/ * method of onSavePrompt override default to avoid being asked if I want to record every time * /.
protected boolean onSavePrompt() {}
Returns true;
}
}

class ConnectionThread extends Thread {}
private int transportType;
public ConnectionThread (int n) {}
transportType = tt;
}

public void run() {}
ConnectionFactory connFact = new ConnectionFactory();
ConnectionDescriptor connDesc = connFact.getConnection ("URL", transportType, null);
If (connDesc! = null) {}
try {}
HttpConnection httpConn = (HttpConnection) connDesc.getConnection ();
httpConn.setRequestMethod (HttpConnection.POST);
httpConn.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
OutputStream out = httpConn.openOutputStream ();
out. Write (Integer.ToString (transportType). GetBytes());
int responseCode = httpConn.getResponseCode ();
If (responseCode == HttpConnection.HTTP_OK) {}
UiApplication.getUiApplication () .invokeLater (new Runnable() {}
public void run() {}
Dialog.Alert ("- SUCCESSFUL CONNECTION-");
}
});
}
If (httpConn! = null) httpConn.close ();
} catch (IOException e) {}
System.Err.println ("IOException Caught:" + e.getMessage ());
}
}
}
}

In fact, this code works very well... but I want to improve it, and I have a few questions:

1. I think that right now, every time I click on the 'Connect' button, I start a new thread. I would like to end this thread in the "run" method, but I don't really know how to access the variable 'ct' from there.   Counsel on how to do it? Or maybe always use the same thread until my application is closed?

2. in the FieldChangeListener of my "Submit" button, I want to access the value of radio box. I did work, but I had to do my 'final' variable What is the right way to do it?

3 - to display a dialog box with 'Successful connection', I just wanted to write something in my main screen. How I do that?

I'm just a bit confused as to just what set up when you use a separate thread.

Thanks for your advice!

Edit: Hidden URL I connect to...

That's what I call a good question! (now I'm wondering why the forums do not work with opera correctly, in any case, here my baldy to the answer format): 1. your thread "dies" when it's over, no need to close it. 2 Yes 3.

A question about external authentication with PHP OCI8 using a portfolio store

Hello

SQL> SELECT * FROM v$version;

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE     11.2.0.1.0     Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

SQL>

OS: Linux Fedora Core 17 (x86_64)
PHP Version: 5.4.14
Apache version (httpd): Apache/2.2.23 (Fedora)

I have a question about OCI8 connection to the Oracle server via portfolio, which I understand is a good practice because we do not have to hard code the users password. I'm trying to read pages 117 and 118 of the book The Underground PHP and Oracle manual online to learn how to set up a portfolio. I proceeded by steps as explained in these two pages (except that at the end I connect, as a normal user, not a privileged user) yet, apparently PHP does not detect the user.

Here's what I write in my script

$connection = 
                oci_connect 
                    (
                        "training", 
                        "", 
                        "php_ora_usr", 
                        "AL32UTF8"
                    );

the training is the name of the user that I use in my PHP scripts to connect to the oracle database and the password is mypassword (is not true, just for the purpose of this thread :)) the code above gives me the following error:)

Warning: oci_connect(): ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 91

Fatal error: Connection step: ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 13

But if I also provide the password which is,

$connection = 
                oci_connect 
                    (
                        "training", 
                        "mypassword", 
                        "php_ora_usr", 
                        "AL32UTF8"
                    );

Obviously it works, but at the same time, this means that my wallet is not operational.

So I'll write here, step by step, how I did according to the instructions contained in the pages 117 and 118 of the above mentioned book and I would be grateful if you could kindly tell where I made the mistake (s)

The following text was performed under my oracle linux (so the dbagroup)

Step 01:_
I created and provided the password for the directory of portfolio

mkstore -wrl /home/oracle/wallet_dir -create

Step 02:_
I created an entry for my oracle user that will be used in my PHP scripts to connect to oracle
user: training
password: mypassword

mkstore -wrl "/home/oracle/wallet_dir" -createCredential php_ora_usr training mypassword

I also checked that the entry was actually created for my user in the portfolio

$ mkstore -wrl "/home/oracle/wallet_dir" -listCredential
Oracle Secret Store Tool : Version 11.2.0.1.0 - Production
Copyright (c) 2004, 2009, Oracle and/or its affiliates. All rights reserved.

Enter wallet password:                
   
List credential (index: connect_string username)
1: php_ora_usr training
$

Step 03:_
I added the following to my $TNS_ADMIN/tnsnames.ora

.  .  .
php_ora_usr = 
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = db02)
    )
  )
.  .  .

Step 04_
I added the following to my $TNS_ADMIN/sqlnet.ora

# sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /u01/app/oracle

WALLET_LOCATION =
    (SOURCE =
        (METHOD = FILE)
        (METHOD_DATA =
            (DIRECTORY = /home/oracle/wallet_dir)
        )
    )
SQLNET.WALLET_OVERRIDE = TRUE
SSL_CLIENT_AUTHENTICATION = FALSE
SSL_VERSION = 0

_ Step 05
The TNS_ADMIN environment variable is already set correctly in * / etc/sysconfig/httpd * so I didn't need to do something for this step

Step 06_
I gave to access Apache (as root) in the directory of portfolio (in fact, it seems that the user oracle (dba) of linux also has the required privileges to grant this access to the apache)

# setfacl -m u:apache:rx /home/oracle/wallet_dir
# setfacl -m u:apache:r /home/oracle/wallet_dir/{cwallet.sso,ewallet.p12}

Step 07_
Restart Apache

# service httpd restart

Step 08_
Finally make a test connection using the connection string php_ora_usr which the entry was created earlier. And the test was not successful, as indicated above

$connection = 
                oci_connect 
                    (
                        "training", 
                        "", 
                        "php_ora_usr", 
                        "AL32UTF8"
                    );

The error message:

Warning: oci_connect(): ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 91

Fatal error: Connection step: ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 13

I would appreciate it if you could kindly shed some light.

Thanks in advance,
Dariyoosh

That gives a good clue to begin with. With your platform/Apache/DB, you might need different ACLs. Test directory and permissions. Check what euid your Apache runs as. Good luck.

a few questions about vcloud

I have a few questions about vcloud. Currently, we use labmanager and are testing vcloud to see how we can apply it to our environment. The current labmanager serves the following purpose:
-create dev and QA 'environments' (configurations) that are copies of production servers so that the changes can be tested
-environments deploy everything from models that are clones of production servers that we update as required
-We have several models of "database" that freshen production according to the needs in order to provide a current recuree version of the database of production for these environments
-computers in virtual environments are able to talk to each other using their 'production' IPs, because IP addresses are closed and accessible only internally within the
-Each VM has an "external IP" that we can use to access the virtual machines from outside the environment. for example, access a Web site through the front-end server within the environment, or RDP to a windows virtual computer within an environment.
I am trying to determine how this translates into vcloud configuration, and I think I have a rough idea. However I have a few questions:
As I understand it, has no way to RDP to a virtual machine in a paralytic 'environment' unless the virtual machine is directly routed, correct? In other words, we cannot copy the configuration that we have above, where the virtual machine has an internal IP address that corresponds to the IP address of the server in production and is used to refer to other virtual machines in the same environment of vApp, however there is also one external IP address, we can use to access this virtual machine via RDP or access its site Web etc.?
I have 2 servers windows 2008, I imported as models, and each time I deploy a virtual using the VAPP model computer, the server seems to restart after 15 minutes be on is, and it seems to go through a windows installation, where it says "preparing your system for a first use" etc. And when it arrives, the administrator password I put is no longer correct (so I have no idea why / what it changes the administrator password). At this point, the virtual machine is useless since I can't connect to it. No idea why this happens each time I have deploy a model VM?

We talk here: http://www.yellow-bricks.com/2010/09/15/vcd-networking-part-3-use-case . Not exactly a step by step for your case to use, but you should be able to get this up and running and configure NAT in the opposite direction.

Questions about an average of response spectrum and frequency of feeding mode.

Hello

I have a few questions about an average of mode. When I generate a sinusoidal signal from one output to two input channels channel to see if my DAQ card works well and vector averaged in the power spectrum for DFT, the amplitudes was different from the previous one of the amplitude, which was supposed to be 1 v peak. They range from 0.5 v to 0.6 v peak. When the calculation of the average model is RMS, the amplitudes were close to 1. I wonder what are the fomulas of RMS and average vector. Does that mean that I could not accurate if I use an average of vector? In a time of frequency response, why I coherences of difference and the amplitudes using the vector and the mean quadratic value?

Thank you

Ningyu

rico1985,

The differences in modes of generation are as they sound: 1 sample output only a sample writing, N samples will be released however many samples configure you for each entry, and the continuous samples released samples continuously until a specified user action happens (you press the stop button or a logic that you created gets fulfulled). The range of Signal output allows you to set a ceiling high and low level of your output signal and it only affects the quality keeping in this beach. Timing to set a deadline for the time between the acquisition of the sample. If a new sample becomes unavailable before the timeout setting, you will get an error. This is useful for looking at a network, because if the network goes down and you stop getting data from a machine and then you would like to know about it. I point you to those videos that are short tutorials on how to make the most of these actions in SignalExpress.The SignalExpress 3.0 Help file is also your first point of contact for all your questions on getting started. These two resources should get you up and running in SignalExpress in no time. (either by the way all your questions answered using these resources) Bravo!

Really simple (hopefully) question about GPIB-USB-HS

I tried to reconnect a GPIB-USB-HS to a network through a PC HP on shelf Analyzer. Before removing the GPIB-USB-HS system about a week or two ago, Network Analyzer (a vintage 1989 HP 8720 vector Network Analyzer) had worked well with the GPIB unit. Now that I reconnected the GPIB device to network monitor, measurement and automation seems not be able to detect the Network Analyzer.

My question is: if my GPIB-USB-HS appear in measurement and automation, and it passes the NOR-488. 2 troubleshooting of HW and SW utility test, it would be safe for me to assume that whatever connection problems I have with the Analyzer network, rather than with the GPIB-USB-HS itself?

Thank you

Armando83

I finally got the connection working again. I just had to tighten the screws on the GPIB-USB-HS to make sure it's a good connection to the Network Analyzer so that it can work.

Thanks again for your help, Dennis.
