Weird behavior of the wifi service

My project showed very weird behavior. As in the connection of signals and slots he was segfaults. I posted that in here . Also, I couldn't create a QTimer object. This all happened after I have use some features of the wifi_service.h file. My CPP code file is subsequently

/*
 * WifiController.cpp
 *
 *  Created on: Jul 4, 2013
 *      Author: Roland
 */

#include "WifiController.hpp"
#include 
#include "GeoNotification.hpp"
WifiController::WifiController() {}
WifiController::~WifiController() {}

int WifiController::toggleWifiState(bool state)
{
    getWifiState();
    int status = wifi_set_sta_power(state);
    return status;

}
int WifiController::getWifiState()
{
    wifi_status_t *status;
    wifi_get_status(status);
    if(*status == WIFI_STATUS_BUSY)
    {
        return 2;
    }
    if(*status == WIFI_STATUS_RADIO_ON)
    {
        return 1;
    }
    if(*status == WIFI_STATUS_RADIO_OFF)
    {
        return 0;
    }

    return 0;
}

The strangeness begins after I call the getWifiState() function. It fills the fi last statement and returns 0. But after these problems occur. But if I don't call this function then, everything works fine.

This will produce undefined behavior:

wifi_status_t *status; // unitialized address
wifi_get_status(status); // wifi_get_status will write into random memory

wifi_get_status waiting for an address of the variable to write to:

wifi_status_t status;
wifi_get_status(&status); // & takes the address of status

You will also need to check the return value of wifi_get_status. An example of code:

  • BlackBerry Curve 9300 Smartphone won't be using the wifi service

    So I'm not the first person to have this problem.  I've been trawling the web looking for solutions, but nobody seems to have any.

    The problem is that my Curve 9300 won't use wireless instead of data network services.  I can connect to wifi fine networks.  The phone searches for networks, connects, puts a little icon on the home screen saying that it is connected to a wifi network.  It lists the name of the network to the top.  Everything is great, except that when you actually use the internet, the phone connects to your data instead of wifi services and you get charged data consumption.

    If you disable network services to try to force the phone to connect to the wifi instead, you get the error message:

    "You are not currently in an area that can handle the communication of data.  Therefore, the browser can't retrieve all of the web pages.  Please try again when you are in a different location, or contact your service provider if the problem persists. »

    To confirm:

    My Data Services are on.

    My APN settings are disabled.

    In Advanced Options, my default browser Configuration is set to Hotspot browser.

    In General Properties, the default browser is Hotspot browser.

    In the Configuration of the browser, the browser is configured to AT & T Mobile Web.  I tried to change it to Hotspot browser but I save the changes and exit the screen, then when I go back to check, it's at AT & T.  It's not save the changes to make the default Hotspot.

    I did a battery pull to see if that would help and after restarting it allowed me to keep the Hotspot as the default configuration but it would not connect if the mobile service has been disabled.  He is now back himself to AT & T and still does not work.

    I read the thread on the forum "BOLD", but for all the people complaining having the same problem, there is still no solution.  I really want a resolution to this because I do a lot of travel and my card sim may not always connect to a local network.  I want to be able to go to a local coffee shop and be able to connect, even if I don't have telephone service in a foreign airport.  I don't understand what is the point of having wifi on a phone if you can't use it.

    OS 6 is available for BlackBerry 9300, please connect to www.blackberry.com and download the latest software from the support section device, install it on your PC and then connect a device with PC by using the USB cable and check for update of the device.

  • Weird behavior of the computer

    Windows XP SP 3
    I wake my computer from sleep mode.
    Wallpaper is slowly deteriorating with a solid color.
    I opened all the windows display little data that it was supposed to-text, input, buttons.  The caused cursor sometimes given to this place to display the cursor was hovering.
    Whenever I open a drop-down menu, the computer sounded like an old phone.
    Make an entry to a window sometimes caused the program to lock up.
    The foregoing was also true for the Windows Task Manager.
    I was unable to restart, then I shut it off and turn it back on.  Same behavior.  Finally I was able to reboot and everything was back to normal.  But then it happened again.  Restart - back to normal.
    This seems to be the odd behavior of Nastyware, but I did some scans (MalwareBytes and Avast) which are things, but I don't know what to do with them other than quarantine.

    I can go back to a System Restore Point, but I would like to know what is happening.
    If the technicians have thoughts please let me know.

    Hello

    ·        Since when are you facing this problem?

    ·        Remember to make changes to the system?

    ·        What are infections you found on the system?

    I suggest that you can run an online virus and malware scan and check the infected files if they are part of a program or toolbars installed on the system etc if it is related to a program, so I suggest you to uninstall the program from the system and check if the problem persists.

    http://OneCare.live.com/site/en-us/default.htm

    As you mentioned in the question, you can also do a system restore to the previous point, when the system worked very well and see if the problem is resolved. I suggest you follow the steps mentioned in the article given below to do a system restore.

  • Weird behavior of Safari Dock icon

    For several months now, I noticed a weird behavior of the Safari icon on the dock.

    Note: I have the Safari Dock permanently icon in the dock if the application is running or not for quick access.

    With open Safari, after periods of inactivity or after the awakening of the mode standby, the icon will lose the small black dot on the bottom that indicates an active application.

    By clicking on the icon or a .webloc file reveals that Safari is still active, but because the icon does not animate as it does when it is launched.

    How can I fix and when Safari * is * open its Dock icon indicates that it * all the time *?

    Probably also related...

    All too often, after similar as scenarios above, Safari actually leave - all on its own.

    How can I fix this too?

    Safari has also been freezing quite often lately have to be re-launched or sometimes requiring a restart of the computer system.

    Something is not.

    Go step by step and test.

    1. Disable Extensions and test them.

    Safari > Preferences > Extensions

    Uncheck 'Enable the Extension' and test.

    Enable the Extensions one by one and test.

    To uninstall any extension, select it and click the "Uninstall" button

    2. Quit Safari if it is open.

    Hold down the option key and click on the "Go" menu in the Finder menu bar.

    Select 'Library', then 'Caches.

    Find the folder "com.apple.Safari".

    Right-click on "com.apple.Safari" and select "move to trash".

    Restart Safari.

    3 remove the test and com.apple.Safari.plist file.

    Empty the trash.

    Quit all applications.

    Hold down the option key and click on the "Go" menu in the Finder menu bar.

    Select 'Library' in the menu dropdown.

    Library > Preferences > com.apple.Safari.plist

    Right-click on it and select "place it in the trash.

    Close the Finder window.

    Turn it back on.    Restart Safari.

    If this does not help, "put back" the com.apple.Safari.plist

    Right click on the trash icon in the Dock, then select 'open '.

    Right-click on the com.apple.Safari.plist and select 'Put Back'.

  • When travel abroad (overseas) and use the WIFI, I can get incoming emails and browse the web, but cannot send emails.

    If I can find the SMTP that is used by the hotel, I can simply change my outgoing SMTP accordingly. But invariably, they do not understand the issue and unless I can find the outgoing SMTP, I'm unable to send.

    Is it possible to automatically pick up the SMTP Protocol out of the WIFI service that I use? How can I change my settings to do this?

    No, there is no easy way to do it, because the SMTP settings are often specific to the provider.  What you might try is to contact your local ISP and see if they can give you an option to send when you are not connected to them.  In addition, you can use webmail to access and send e-mail.  If your ISP doesn't have this option, there are several free accounts or cheap you can register for (gmail, hotmail, yahoo, etc.).

  • Weird reading during the use of Stream.play ("mp3:file")

    Hello!

    I am trying to set up a selection side server for playback of mp3 files, if I fall into a weird behavior of the FMS.

    I use the last FMS 4.0.2

    Here's how I try to publish the stream (ActionScript on the server side):

    var s = Stream.get ("boo");

    If (s) {s.play ("mp3:rhcp", 0) ;}}

    Client side, I try to play using NetStream.play ("boo"). However, the sound quality that I get is really weird. The sound goes slower and faster and stops for a split second. He can play properly for a few seconds, but that's all. Sounds like a problem of decoder for me, or a bitrate conversion problem.

    When I play the stream with NetStream.play ("mp3:rhcp"), the reading goes well.

    I tried several MP3s with different flow rates, but they all have the same problem.

    It looks like a bug to me, so I'm expecting Adobe to comment on this one.

    Hello

    Please try the FMS 4.0.2

    It is a little strange to see the problem, but I would like to know your settings on the client side. What player flash you use (although I doubt that it is a question that your reading of the original file is ok), and what is the length of the buffer that you used? There are known issues with the length of the buffer to 0. Can you try and change the length of the buffer in some other values and see if that helped to get the best quality?

    Thank you!

    As a solution, I think that if a system component is damaged I shuould fix first.

    In fact, I did a full upgrade to Windows 7 (build even) with the OS DVD.

    I must mention about the extraordinary capabilities of Windows 7 on the upgrade.

    After all the upgrade process which took about 2 hours to "Installation of Windows 7" discovered that .NET framework 4.0 is damaged and repaired. And I could start ICS.

    Without all this hassle if you could try to reinstall .net Framework 4.0, I think that this problem will disappear.

  • [MAF - AMPA] Strange behavior of the MAF with REST service

    Hi MAF Experts.

    I just noticed that there is a strange behavior in my application of the MAF. The first loading of the page, amx:page does not make its contents (of REST). However if I kill the app and relaunch the app, content appears.

    Pattern:

    1. Start of the CRG App
    2. Opening of session
    3. Dashboard (the content is rendered)
    4. Go to any other aspect (lets say a list of products)
    5. Open product list (content do not get returned)
    6. Kill the MAF application
    7. Start of the CRG App
    8. Dashboard (the content is rendered)
    9. Go to the product list
    10. List of products (content gets rendered)

    I put a few breakpoints on EntityCRUDService and RestPersistenceManager.

    So far it return the list of entities and display the correct data (from watches in debug mode)

    Last thing I noticed is the red color below. She defined the EntityList with the new value of REST (This displays a correct value).

    TaskExecutor.getInstance (.execute (isDoRemoteReadInBackground ())

    , () -> {

    Auto Sync all actions pending first, pass false for inBackground because

    We want to process actions pending before the reading distance

    getDataSynchManager (.synchronize (false));

    The list of entities < E > = executeRemoteFindAll();

    If (entities! = null)

    {

    When an error occurs (for example server is not available, the method returns the value zero)

    setEntityList (entities);

    }

    });

    Any suggestion?

    All the rest service are configured with AutoQuery = true in the persistence - mapping.xml

    See you soon,.

    Hendry,

    Thanks your testcase, I was able to understand the problem.

    It turns out that MAF 2.1 has problems dealing with the advanced way in which AMPA running background tasks with the help of a thread in all of features.

    We have slightly modified the implementation in AMPA to use one thread per function and now the update issue is resolved. I sent you a link to new construction.

    We will publish the new generation soon on GitHub so that others can benefit in the same solution.
