First result on Google

public static boolean isInteger(String s) 
{
    try 
    { 
        Integer.parseInt(s); 
    } 
    catch(NumberFormatException e) 
    { 
        return false; 
    }
    return true;
}

Use this and it will return true or false depending...

I dont have the slightest clue what you are trying to acomplish. That said...

You can do in your Player function:

return playerChar.split("(?!^)");

Then in your main:

String[] PeopleDoSomeWeirdShit=User.Player(1);

And it will work. To access the result:

System.out.println(PeopleDoSomeWeirdShit[0]); //Will print out "W"
System.out.println(PeopleDoSomeWeirdShit[1]); //Will print out "a"
System.out.println(PeopleDoSomeWeirdShit[2]); //Will print out "r"
System.out.println(PeopleDoSomeWeirdShit[3]); //Will print out "r"
System.out.println(PeopleDoSomeWeirdShit[4]); //Will print out "i"
System.out.println(PeopleDoSomeWeirdShit[5]); //Will print out "o"
System.out.println(PeopleDoSomeWeirdShit[6]); //Will print out "r"

For prettier stuff:

for (int i=0;i<PeopleDoSomeWeirdShit.length();i++
{
    System.out.print(PeopleDoSomeWeirdShit[i]); //Will straight out print "Warrior"
}

Also, for those who missed the notice, the code snippet competition is being extended to the end of August for submissions

:(

He was obviously being sarcastic....

Due to the fact it is not possible (in web apllications) to open a words file using Java, it is required to directly put the words string separated by a | into the string variable. Modify the string in the initGame() function in the script (line 59).

Since when? JS can do it perfectly AFAIK. Obviously we wont get into Java....

Stacktrace. I thought it was obvious that foldername was a placeholder, sorry.

Hello

Im using the FileUtils.copyDirectory method but it gives me the error of "Failed to list contents of foldername". I know the folder exists and I can write there because creating a file works.

What could be wrong?

I perfer using a normal for, not a foreach.

I perfer numeric and the values inside are

key -> vale

Nothing complicated AFAIK.

$_COOKIE is associative array. If you want to turn it to numerically indexed you can use array_values() function. But you are loosing valuable information. You can list values this way:

Ill try this.

Im testing local then deploying on shared hosting....

Hey, could I do something with libVLC?

It says XE4 is for iOS, Windows and Mac, so no Linux anyway.

Then OS X and Windows....

for ($i = 0; $i < count($_COOKIE); $i++) 
                {
                     echo ($_COOKIE[$i]);
                }

Is there a reason this doenst work?

Hello

Lets say in the localStorage object I have the following:

Apple = red
Potato = brown
Gum = blue

And I want to search thru it for the word Potato and then get its value (brown).

How could I do this?

Im thinking:

for (var i=0;i<localStorage.length();i++)
{
    if (localStorage[i]=="Potato")
    {
    var somevariable=localStorage[i].value();
    break;
    }
}

Forgive sintaxis errors as I just thought it up in 15 seconds.

The version is FireMonkey from Embarcadero.

I am imagining its the bottom link saying Delphi XE4

Hello

Im having problems setting a cookie in PHP (using the Magento platform). The page is at:

http://example.com/step1

When I click on a link here, a iframe opens up. This iframe opens up and is located at:

http://example.com/somewhereelse/index.html

I check a checkbox or I dont. If I check it, a cookie is set to true (lets say whereelse = true) else its set to false (lets say whereelse = false). This works. It sets it to true and false.

After clicking a link, that basically goes to the cart it goes to

http://example.com/step2

But I do not see the cookie at all.

Ive also tried using localstorage and that DOES WORK....but from PHP I cannot access it later.

If more information is needed, please ask and Ill try to put it if known what is asked.

Thank you.

I really doubt that there are multi-platforms drivers. I haven't seen any although that still doesn't mean there aren't any. Which Delphi are you using?

Not for me, for a colleague. No idea at all.

I explained that the only way to do this (if there is no multi-platform drivers) is to load one for each platform (only three: Linux, OS X and Windows) but the binary would be huge....

Hello

Is there some kind of multiplatform library for Delphi (with its SDK) to access webcams while programming? The goal is to take still images but Ive only found ones that are compatible with Windows.

Dani hates me :P so here you go. Updated:

I hate you Dani :P I have to update both snippets....

I think that an extension would be a good idea, the more people entering the better at the end of the day.

For DaniWeb of course. For the developer who wants $300 in Amazon, no :P

This can be done by assigning value to JAVA_OPTS variable. Look into some documentation on JAVA_OPTS as well to have more knowledge. One important information you do need to know is that each time you deploy an application on the server, the application thread will use the memory added on JAVA_OPTS. So you need to be careful if you are running multiple applications on the server.

How do I modify this in Linux?

Sometimes I update my web service JAR by deleting the old one, are you tried to use JWS(tJWS not clear from your description)

I simply delete the web service jar, wait for the undeployed message to appear, then copy the new one and wait for the deployed one to appear. Done.

dani can you increase duration of competition by 2 weeks or so.I m a bit involved in my app for now.It will take a week or two after that i will start working for this competition.Or else riahc3 ,diafol and pritaeas will take those rewards. Let me take third. :'(

Well, in fairness to other members, The API has been here about a month and so has the contest. Extending wouldnt be fair to others who have worked on the API (such as pritaeas; my entry is more of a mock as I know a code sample has no way of winning) because those others who have submitted a entry, now have to improve on their work to make sure they win...

I am seriously considering extending the competition because it seems that the first few weeks were spent learning the API and creating frameworks around it, as opposed to developing the meat of an application.

As I mentioned to IIM, pritaeas would for example better his app to make sure he wins (I dont care about my entry as its more of a mockup than anything; The more entries the better)

But if you do extend it, lets see it promoted more so we can get some people involved!

I can upload small texted file but not large ones....

Let me check for a limit...

It gets weirder and weirder....

I had some simple text in the text file I created in Notepad. Lets say "The fox"

I am able to transfer that thru PHP and it creates the file with "The fox" inside

Now lets say a text file from Java says "The fox jumped over the fence". That doesnt transfer.

What I did is I copied that text from the Java one to the Notepad one and saved it. But when I transfer now the Notepad text file it just says "The fox jumped". Nothing else.

Why?

OK, a basic txt file created in Notepad gets transfered yet a text file created by Java doesnt.....

I hate this shit.

Odd..........ftp_put gives me a warning that it cant created the file.

Well considering riahc3 and you are the only two people who have submitted entries so far, and there are going to be 3 winners, I'm pretty sure you'll be one of them based on how things stand right now.

Related to what pritaes just posted, can more than one entry per person count? Mines were just simply examples but since noone else has submitted anything....

I ask because whatever pritaes makes will obviously be better and Ill be left out of the contest...

Perhaps I'll make a run for 1, 2 and 3 :D

:(

From what diafol just posted, guess Ill be third now :(

We overwork pritaeas....

$name=$_FILES['file']['name'];
$conn_id = ftp_connect("127.0.0.1");
$login_result = ftp_login($conn_id, "user","pass"); 
ftp_pasv($conn_id, true); 
$upload = ftp_put($conn_id, $name, $_FILES['file']['tmp_name'], FTP_ASCII); 
exit;

Done.

Also, transfering the file with Windows Explorer works so its not a permissions issue....

Did some conditional ifs and all of them return true....

<?php



                $name=$_FILES['file']['name'];








                $conn_id =  ftp_connect("127.0.0.1");

                $login_result = ftp_login($conn_id, "user","pass"); 

                ftp_pasv($conn_id, true); 





                if (move_uploaded_file($_FILES["file"]["tmp_name"],getcwd()."/".$name))
                    {
                        echo ("work");


                    }
                    else
                    {
                        echo ("doesnt work");
                    }



                $fp = fopen(getcwd()."/".$name, "w");

                if ($fp==false)
                {
                    echo ("problem opening file");
                }



                echo ("hi");
                fclose($fp);



                if (ftp_put($conn_id, $name, getcwd()."/".$name, FTP_ASCII))
                {
                    echo ("working correctly");
                }
                else
                {
                    echo("problem");
                }


                exit;

BTW, this has worked in the past FTPing to this server so....

Well, Im going to continue to see what I can do with this.....

Am out of ideas right now. When I'm home I can try your code.

Thank you, Ill see them tommorow.

Im reading the documentation but I really dont see the problem..........must be something small....

Its visible, meaning I see the file; As a matter of fact, the server is next to me, I see it appear in the explorer but when I open it, it is empty when on the local side, it has text inside.

Besides, yes, I should; Remember the file is created but no content is inside.

It opens the root folder, are you sure you have write permissions there? Perhaps you need to ftp_chdir to a different folder first

Yes, theorically I should.

Its the root server to where I FTP with the user Im using all the time.

Should I chmod before it or something?

if (move_uploaded_file($_FILES["file"]["tmp_name"],getcwd()."/".$name))
                    {
                        echo ("work");


                    }
                    else
                    {
                        echo ("doesnt work");
                    }

Changed to this and it prints out work but now it says:

Warning: ftp_put() [function.ftp-put]: Could not create file. in C:\testing\page.php on line 43

Hmm....FTP server is correct AFAIK.

I suggest you do some error checking to see what exactly fails. Is the uploaded file in your current work directory? Does ftp_connect return a resource, do ftp_login and ftp_put return true?

Yup, Ill have to work if it returns true or false because there is no error message...

Ill do some if statements to print out...

WOW, for now pritaeas is going to take the first place price and Im going to take the second? :P

Well I might as well put in my code samples as entries...

<?php



                $name=$_FILES['file']['name'];


                print_r($_FILES);





                $conn_id =  ftp_connect("127.0.0.1");

                $login_result = ftp_login($conn_id, "user","pass"); 

                ftp_pasv($conn_id, true); 





                move_uploaded_file($_FILES["file"]["tmp_name"],getcwd()."/".$name);

                $fp = fopen(getcwd()."/".$name, "w");


                echo ("hi");
                fclose($fp);

                $upload = ftp_put($conn_id, $name, getcwd()."/".$name, FTP_ASCII); 


                exit;

Problably missing something obvious :(

<?php



                $name=$_FILES['file']['name'];




                $conn_id =  ftp_connect("127.0.0.1");

                $login_result = ftp_login($conn_id, "user","pass"); 

                ftp_pasv($conn_id, true); 

                move_uploaded_file($name,getcwd()."/".$name);

                $fp = fopen(getcwd()."/".$name, "w");


                fclose($fp);

                $upload = ftp_put($conn_id, $name, getcwd()."/".$name, FTP_ASCII); 


                exit;

Is this what you ment or did I understand you incorrectly? (Doenst work)

$name=$_FILES['file']['name'];




                $conn_id =  ftp_connect("127.0.0.1");

                $login_result = ftp_login($conn_id, "user","pass"); 

                ftp_pasv($conn_id, true); 

                $fp = fopen(getcwd()."/".$name, "w");


                echo ("hi");
                fclose($fp);

                $upload = ftp_put($conn_id, $name, getcwd()."/".$name, FTP_ASCII); 


                exit;

This code "works" but the location where I FTP the file TO is empty. There is no text content.

Im not sure if move_uploaded_file has anything to do with it.

<?php



                $name=$_FILES['file']['name'];




                $conn_id =  ftp_connect("127.0.0.1");

                $login_result = ftp_login($conn_id, "user","pass"); 

                ftp_pasv($conn_id, true); 

                $fp = fopen(getcwd()."/".$name.".txt", "w");

                /*I THINK I NEED SOMETHING HERE DIFFERENT THAN THE CODE IVE SEEN*/

                fclose($fp);

                $upload = ftp_put($conn_id, $name.".txt", getcwd()."/".$name.".txt", FTP_ASCII); 


                exit;

Hmmm cant quite get it...

You need to use move_uploaded_file first I think, to move the file from the temp directory to a permanent location (during your upload). If it is successful, then delete it.

Doesnt ftp_put do this?

Am not sure what kind of files you are ftp-ing, but I'd consider FTP_BINARY.

Only text nonunicode files

Sorry, my bad.

No problem. Now we are getting somewhere :)

<?php
                print_r($_FILES);
                exit;

This is the result:

Array ( [file] => Array ( [name] => filetest.txt [type] => text/plain [tmp_name] => C:\xampp\tmp\phpCB31.tmp [error] => 0 [size] => 267 ) )

OK, thats one part. Now how do I continue on to FTP that over?

Example code Ive thought up now:

$thefile=$_FILES['name'];
$conn_id = ftp_connect("127.0.0.1"); //example IP
$login_result = ftp_login($conn_id, "username","password"); 
ftp_pasv($conn_id, true); 
$fp = fopen(getcwd()."/".$thefile.".txt", "w");
/*HERE I THINK IT WOULD HAVE TO MAKE A COPY OF THE FILE WITH THE CONTENTS*/
fclose($fp);
$upload = ftp_put($conn_id, $thefile.".txt", getcwd()."/".$thefile.".txt", FTP_ASCII); 

This Ive thought up basing myself on some examples on the net. Anything wrong or different I should do???

If you could afford more memory to your JVM on the server machine. You could increase it

So how can I do this on Tomcat?

Did you search this forum (PHP) ?

Yes. Maybe the terms I used were not correct/valid so thats why it didnt show me any valid solution.
