I would appreciate your help on how to configure a gmail in a way it ask for the password everytime I connect?. In the only way I can configure it I have to include the pw when configuring the account and after that it do not ask for pw so everyone that shares my iPad can oppen my mail with no pw required.
Thank
The iPad is designed to be a single user device, and there is currently no way to password protect the Mail app - even removing the account password from Settings > Mail, Contacts, Calendars will just prevent new mail being downloaded, it won't hide those that have already been downloaded. There is this work-around for the app : https://discussions.apple.com/message/13127632#13127632 . Also there might be third-party email apps that feature password protecting.

How can I reset my Mac to default settings? Or how can I reset it to a prior date? My Mac has a virus and I would like to get rid of it. I would appreciate your help concerning this matter.
To restore it follow these instructions: What to do before selling or giving away your Mac.
Before you do the above check out the following;
Helpful Links Regarding Malware Problems
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide, AdwareMedic, or Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari.
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one. -

to search for networks. it shows no services.Ok thank you so much! Although I ended up taking the sim card out of my new Iphone and reinserting it into my old one it finally let me restore it! So thanks once again this really helped!

I have upgraded my Iphone 4s to 7.0.3 and after that my phone is not charging at all if i leave my phone for charging for more then 24 hours it will charge upto 50%. How do i solve this issue ?? pls suggest ??
Even if it is a hardware problem they should fix it regardless of warranty. If you buy a car and after 1.5 years the doors fall off due to a failure in their design and construction, do you think the car manufacturer could pull off what Apple is trying to do? Yes the car still delivers its primary objective of driving from A to B, but significant functionality has been lost due to their fault.
It is the same with this iPhone wifi problem. Apple are a disgrace, I have had significant Apple Hardware failures with my MacBook Pro and iPhone within 2 years of purchase. Pathetic quality. -
Hi All,
I am trying to execute the below code as provided from one of the blogs. i am able to run the job only once based on a file watcher object(i.e. for very first time) and after that the job is not running at all and if i schedule the job to run automatically based on interval of 10 or more minutes it is executing properly). Please let me know or guide me if i have missed any step or configuration.that is needed.

This week is my 8thweek of learning java and I am finding it tougher and tougher as the weeks go by. I have been working on this StudentSystem program for about a week now. I have done all I could but I am left with one part which I am finding it tough to handle.
I would appreciate if a good samaritan could add this code for me. I am at my wits end.
The program I am trying to write is supposed to add students with their personal information and then display them in a GUI.
I should be able to select a student and add a grade for that student.
Finally I should be able to get the average for all the grades added for this student and display the average grade.
My challenge is how to obtain all the added scores and show the students average in a new model.
I was thinking of adding a "Get Average" button , which will pop up a new window(Average) displaying the average of all the scores for the Student.
I just can't figure how to link this average display window to the Get Average button.
A student can have any number of grades.
Your help will be very much appreciated
Thanks in advance
Little Delmarie.

* @paFirst of all, this is an extremely advanced project for someone only having 8 weeks of experience. I'm not sure what the "real story" (e.g., the professor teaching the course majored in Public Speaking, student told counselor that she could handle skipping the preliminary course, student transferring from college that used another language as the core language) is but I'll give you my 2 cents anyway.
Suggestions:
I personally would start over keeping the following in mind.
1.) Write a student class that encapsulates/holds the student's personal information, history of grades, computes average and whatever eles is needed from the student.
--the history of grades can be stored in any list structure, preferably some sort of array, since all you going to do with them is average them.
2.) Keep your window display as simple as possible. Basically from my understanding you'll need at a minimum:
JTextField First_Name, Last_Name, Street_Address, City, State, Zip, Average_Grade;
You can either have labels for these or fill them in with their respective labels if they are empty.
JButton New, Average, Add
I don't know the components name, but I'm sure Java has some sort of drop down list that you will need so you can add students' names to it as they are added.
The following is a scenario of how this will come together, initially assuming there are no students:
Your program starts with all the JTextFields containing their repsective labels and grayed out, it's an option or method in JTextField. The drop down list is empty. The teacher has to press the New button, at which time the grayed out text fields become editable. Teacher completes filling out the form and presses the Add button. At this point, your program gathers the information from the text fields (First_Name, Last_Name...) and instantiates or creates a new Student object from your Student class and adds the student name to the drop down list. Now that the new Student object has been created and constructed, you need to store it in you lists structure for later retrieval or writing to disk later.
Now there is a student in the database. So the teacher comes along and wants to average Davey's grades. The teacher goes to the dropdown list and selects Davey's name, which triggers an event in you program. You retrieve the name of the student from your window's drop down list, pull the Student record from your list structure, ask it for the average grade and populate the other text fields in your window with the records information (First_Name, Last_Name, Address...). The Average_Grade text field is made editable and the value of getAverage from the Student object is inserted. The chain of envents keep rolling much in the same manner.
If you made it this far and much of what I said is confusing, then I believe you are in over your head and I'm sorry. If much of what I said sounds similar to what you have or at least you understand a majority of what I said, then let me comment on where you started going awry.
Regarding this project, I believe you envisioned each chain of events spawning a new window, such as user clicks the New button so your program would spawn a new window titled "Enter new Student Information."
You can represent all the task and modes required in this project using a single window display by manipulating the components within the window. If you are looking at a window and suddenly a text box is grayed out, the program is sending a signal to you that its mode has changed.
I hope this helps and good luck. -
SUddenly, when typing text on my IPad, full stops followed by a capital letter. Keep occurring. Also when I tap the back erase. Arrow, everything that I have previously. Typed gets erased. Would love some help with this, have looked in settings but none the wiser. Thanks.
Do yo have the "." shortcut set to On? (Settings>General>Keyboard). If you do, it may be that you are hitting the space bar twice without realizing it. This will insert a period.

Would Appreciate Your Help - Tables Not Connecting/Pages Not Being Generated
Hi,
I have a recipes section in the site I'm building.
There are 7 categories from which a user can click on.
The first page of each category has a form on it for users to enter a new recipe. Once they've entered a new recipe, the title of it is shown above the form. Here's where the problem starts.
First category is desserts, and I entered two dummy titles as a trial run, Apple and Blueberry. No matter which title I click on, I am taken to the page for Apple. And the thing is, when I click on Blueberry, the url address shows Blueberry as the recipe ID. Which indicates to me that it's recognizing it, but not going to the recipe. What am I missing? Could someone please advise as to how I can have the necessary pages created?
There are two separate tables in my database, Recipes, and Categories. The second table was created after I made the SQL connection in Dreamweaver. Do I need to reestablish the connection, because of when the second table was created?
Thank you.
This is the SQL Join that I have on both the Main Desserts Page, and the one to which a recipe should appear on, Recipes Desserts:
$query = "SELECT title".
"FROM recipes, categories".
"WHERE recipes.cat_id = categories.cat_id";
"AND category = desserts";
Here's the code on the Main Desserts page:
<div id="background">
<div id="navbar2">
<ul>
<li><a href="desserts.php">Desserts</a></li>
<li><a href="drinks.php">Drinks</a></li>
<li><a href="fowl.php">Fowl</a></li>
<li><a href="meat.php">Meat</a></li>
<li><a href="pasta.php">Pasta</a></li>
<li><a href="seafood.php">Seafood</a></li>
<li><a class="last" href="vegetables.php">Vegetables</a></li>
</ul>
<p>
</div>
<div id="items">
<ol>
<?php do { ?>
<li><a href="recipesdesserts.php?recipeID=1<?php echo $row_GetRecipes['Title']; ?>"><strong><?php echo $row_GetRecipes['Title']; ?></strong></a></li>
<?php } while ($row_GetRecipes = mysql_fetch_assoc($GetRecipes)); ?>
</ol>
<p><a href="<?php printf("%s?pageNum_GetRecipes=%d%s", $currentPage, max(0, $pageNum_GetRecipes - 1), $queryString_GetRecipes); ?>">Previous</a> Showing<?php echo ($startRow_GetRecipes + 1) ?>...<?php echo min($startRow_GetRecipes + $maxRows_GetRecipes, $totalRows_GetRecipes) ?> out of <?php echo $totalRows_GetRecipes ?> <a href="<?php printf("%s?pageNum_GetRecipes=%d%s", $currentPage, min($totalPages_GetRecipes, $pageNum_GetRecipes + 1), $queryString_GetRecipes); ?>">Next</a></p>
</div>
</div>I'll try to paint a better picture.
I have two tables in the database.
First table is Recipes. The fields in this one are: Title, Ingredients, Prep, Serves.
Second table is Categories. The fields in this one are: Title, Desserts, Drinks, Fowl, Meat, Pasta, Seafood, Vegetables.
User 1 enters the following into the form:
Title: Apple Strudel
Ingredients: Apples, Flour, Water
Prep: Core and slice apples, etc.
Serves: 6
User 2 enters the following into the form:
Title: Blueberry Pie
Ingredients: Blueberries, Flour, Water
Prep: Wash blueberries, etc.
Serves: 6
Both titles now appear on the Main Desserts page, which is what I want. When a user clicks on the title, "Apple Strudel," they are taken to the page with that recipe on it. When a user clicks on the title, "Blueberry Pie," the ending of the URL address is recipesdesserts.php?recipeID=1Blueberry, but the page that's generated shows the recipe for the Strudel.
Does that help at all?
Thank you. -
I hate this new upgrade. I basically can't use this browser anymore. I only need firefox to do a few things correctly but if it cannot do these things I cannot use it<br />
1. If firefox crashes (which it does every 30 minutes it just closes completely) then I need for it to be able to restore / recover all previously opened windows when I start it back up again. It does not do this anymore.<br />
2. I use the bookmarks toolbar all the time but frequently it shows up completely blank. So now the only way I can see the bookmarks is if I go to options and deselect bookmarks toolbar and then reselect bookmarks toolbar.
This is so frustrating and worse you make it so you cant do rollbacks! That is insulting and makes me want to not use your browser. A browser is a critical tool not a toy but you guys won't stop playing with it.Hi joshuad31,
Sorry you are having problems. It should not be crashing and should not be messing up your bookmarks. I do not have any such problems.
*If Firefox is actually crashing, as opposed to hanging then a couple of the Crash IDs would help.
** see [[Firefox crashes - Troubleshoot, prevent and get help fixing crashes]]
* if firefox has been frequently hanging and restarting offering the option to restore sessions then that has probably overloaded the session restore and you will need to delete the multiple copies of files.
** see [[Firefox hangs or is not responding - How to fix#w_delete-duplicated-session-restore-files]]'''_delete-duplicated-session-restore-files'''
** you will loose information doing that, normally I would suggest bookmarking the open tabs, but I am not sure that would work for you.
To get Firefox running again you may initially need to use Firefox's safemode and disable all your plugins. Or do a reset.
* [[Troubleshoot Firefox issues using Safe Mode]]
*[[Reset Firefox – easily fix most problems]] (Read the warnings before you try this)
I note you have VMware, scripting software and an enterprise edition extension. Is this machine used in an enterprise / corporate environment ?
I will deal with the bookmarks toolbar issue later, crashing/hanging is a higher priority. -
As i told i have Windows 7 Ultimate 64bit version. I install java and have problems with Java Deployment Toolkit and Java(TM) Platform SE. It won't show in add-on. I cant watch movies. When I play movie it says java is missing but when I use IE I can watch some movies. I try reinstaling Java and even reinstall Windows. But problem was still there. I run java check (from Firefox) to see if java is installed and it confrmed. I even try diferent versions of Java and Mozilla. I even use JDK and JRE. I install java for 64bit and mozilla is also for 64bit version of system.
I have another laptop with 32 bit version and everything works great. Installation procedure was same (only used 32bit versions of softwares).
When I go to control panel and java options (windows 64bit) enable java content in your browser is marked. But in advanced tab default java for browser (mozilla family) is unmarked. And when I mark box and leave (apply then ok) and return box is empty. It wont confirm. In 32bit version of laptop i have alsou java plugin but in 64 bit it is not there. Here is a picture what I was talking about. This is on windows 32 bit for 64bit is some just box for mozilla family is empty and under that java plugin do not exist.
[code]http://s23.postimg.org/dl4dun4p7/Untitled.jpg[/code]
hope someone have solution!!you don't have to reinstall firefox or java, you can just download and install the 32bit-java next to your currently installed java version. it should then be picked up by firefox and be displayed under firefox > addons > plugins...

Would appreciate your help - my Contacts does not sync into Desktop, it freezes
Can anyone help me?
From my Zire31 I sync with a USB cable into Palm desktop.
The Contacts used to sync allright, but now it does not at all. Other things [memos etc.] do sync, but when the process gets to contacts, it freezes on "syncronizing contacts" on both Desktop and Zire, and stays like that for hours untill I reset!
I tried sevaral settings with the Hotsync manager but none help.
Would be thankfull fro your advice.

Post relates to: Zire 31Thank you, HardbeatZ. I did what you suggested and the software found 6 possibly corrupted files, all of them in the calender, none in the contacts.
Do you know how I should proceed?

VMA fairly urgent, would appreciate your help VCAP is tomorrow.
Hi All,
I Would be eternally grateful if anyone had any advice on this problem. I have installed and configured a new instance of the vMA, added it on the domain, added target servers however I don't seem to be able to run anything against hosts resxtop for example. It doesn't seem to matter if I run it with local credentials or AD nada! the prompt just bounces back at me. I know the credentials are correct for everything I have tried, I have confirmed system time, tried both American keyboard/UK, rebooted the box I know DNS is ok and have tried IP's regardless. Its a long shot but if anyone could take a look at the attached screenshot and let me know if I am doing something silly I would be grateful. I really want to nail this as its in my VCAP tomorrow, I feel like I know the relevant commands but want to actually test it.Well that fixed it!!! What the fluffing hell was that all about, hope I don't have to contend with that sort of rubbish in the actual exam? How did that sort it mate? What was wrong is it a known issue/bug or am I a muppet?

I have an iphone 5 and i would like to connect it to a radio or speakers to play music but i dont know which cable is used and where can i get it.
Depends on the home radio. You can connect a 3.5mm jack to the iPhone and, if your radio has a 3.5mm input, connect that to your radio. If your radio only has RCA style connectors, you can buy an adapter like the one pictured.
Regardless of which method you use, make sure to select the correct input on your radio. You'll also need to turn the volume on your iPhone all the way up.
I hope that makes sense. If not, what's the model of your radio? -
