When posting your question please:- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
- Read the question carefully
- Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
- If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

Hi,
i am creating a user register class using pdo prepared statements etc. But it looks like, something is going wrong in my following code.
I am getting error on the following code in bold -
public function isUsernameTaken($username)
{
$st = $this->getPdo()->prepare("select count(*) as cnt from ".
$this->getDbUserTable()." where username=?");
$row = $st->execute(array($username))->fetch();
if($row['cnt']==0)
{
return false;
}
return true;
}
the error is - Call to a member function fetch() on a non-object
Any idea about the error?
Thanks

According to my reading of the PHP manual, $st->execute() will return a bool, indicating success/fail of the SQL call. If it succeeded, you can then call $st->fetch() to get the results.
Simple, really.
Cheers,

How do I restart or shutdown the machine on the same network or access the files in other machines(Computers)?
|
|
|
|
|
|
|
Many ways, but it depends on the machines, what OS they are running what type of network connections they have, etc., etc. Try a more explicit question.

If you have SSH set up, all that is easy... just SSH into the machine you want to control and you can use regular command line commands to restart/shutdown. The alternative to SSH would be to have some sort of remote viewer like VNC, although VNC is not really as flexible as SSH (but it does allow you to view things with a GUI).
To access files, you'll need something like FTP or a Samba share.

You can run the system level call play[^].
If you want to do it within your program, you'll have to use ALSA[^] (a low level API) or use something that works at a higher level of abstraction such as PulseAudio[^].

Hi, guys!
Does anyone know why sometimes gdb tread 'next' as 'continue'?
I tried to debug a generated C++ executable file on linux with gdb, and set a break point in a function 'b myfunction', it inform me that breakpoint setted successfully.
Next, I give the command 'r' to run the program in gdb, and it breaked right at the point 'myfunction', so I started typing 'n' in order to go through whole function, but gdb told me program exited normally!!!
There are many lines in this function, and gdb didn't stop at the first statement of this function, it just went through the left whole program.
Any help would be appreciated
Thanks in advance！

I haven't used gdb.. but in the MS debugger, if you want to step INTO a function as opposed as just NEXT line, it's a different command. Make sure that's not the case. Also, have you tried setting your breakpoint within the body of the function?

How do you include your css in your <head></head> and how do you define the label?
|
|
|
|
|
|
|
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css" />
</head>
I just copied this from the first Google result for the search "CSS head link" (it was w3schools.com). You might want to try that next time.
Cheers!

I have an interesting problem with setting up scheduled jobs.
I need to set up a job that will run at 5pm Eastern time when the server is running GMT/BST. Currently we set it up as 10pm, however as daylight saving comes in a week earlier, it will be running at 6pm eastern for that week. Any idea of an easy way to get around this? Changing the server time zone is not an option.

Add CRON_TZ=US/Eastern in the crontab file. All cron implementations don't support that variable, check man 5 crontab on your server.

Doesn't look like it, I'll have my sys admin look into it.

If your cron does not support CRON_TZ (see answer drom markkuk), you may write a small utility or bash script that detects non-matching times. Then add two entries to your crontab file:
10 0 * * * /usr/local/bin/TzMatch && MyCommand
# or must it be 9?
11 0 * * * /usr/local/bin/TzMatch || MyCommand

It looks like I'll do something like this.

Hey Guys,
I am new to Nutch. I am part of a IR research team & need to create a setup where in I need to crawl Microsoft's Dataset with Nutch. After googling for a while, I didn't get any tutorial or help. Can anyone guide me for the same?
I am using Nutch 1.4 on Ubuntu 11.10 & Eclipse 3.7.
Till now I am able to crawl public network from my Nutch setup integrated with Eclipse...
Is there any tutorial or wiki explaining how I can achieve this - or any other dataset kept on File System? If not, can you help me please....
Thanks in advance.
Cheers!!!

How do I start Apache as a thread from my process. Does it require any change in the configuration? Can you please guide me through it .
Regards,
|
|
|
|

You have to have the rights to do so. In perl I usually use back ticks to execute a command. Just assign the results to a variable. I think you are supposed to use exec, but .... well, I learned the other way 
If it moves, compile it
|
|
|
|
|
|
|
The exec() call creates a new process and will not be a thread of the program from where I am calling. I am concerned about starting apache as a thread . Can you please give some more info ...
Regards

Like Peter states, you can't do what you are asking. I didn't search to check out embedding apache, but that's another subject.
Apache is a service. It runs on it's own.
If it moves, compile it
