  • How to deploy an application with firewall permissions on Mac?

    - by user264878
    I've bundled a jar file as a mac application using jar bundler. I'm now trying to create an installer for this app so that: 1) The application will be placed in the applications folder 2) The application is added to the list of permissible apps in Mac Application Level Firewall Also, I have several example files I would like to include with this application - what is the best way to make these available to the user. Someone suggested I have the mpkg file launch a dmg file which would contain these files, but this seems circuitous. Thanks

  • Java deserialization speed

    - by celicni
    I am writing a Java application that among other things needs to read a dictionary text file (each line is one word) and store it in a HashSet. Each time I start the application this same file is being read all over again (6 Megabytes unicode file). That seemed expensive, so I decided to serialize resulting HashSet and store it to a binary file. I expected my application to run faster after this. Instead it got slower: from ~2,5 seconds before to ~5 seconds after serialization. Is this expected result? I thought that in similar cases serialization should increase speed.

  • Problem carrying Session over to other pages

    - by AAA
    I am able to login a user, but while processing to the next page (memebers area) I can't display any user info let alone print the $_SESSION[email]. I am not sure what's up. Below is the login code and the testing members are page. Login page: session_start(); //also in a real app you would get the id dynamically $sql = "select `email`, `password` from `accounts` where `email` = '$_POST[email]'"; $query = mysql_query($sql) or die ("Error: ".mysql_error()); while ($row = mysql_fetch_array($query)){ $email = $row['email']; $secret = $row['password']; //we will echo these into the proper fields } mysql_free_result($query); // Process the POST variables $email = $_POST["email"]; //Variables $_SESSION["email"] = $_POST["email"]; $secret = $info['password']; //Checks if there is a login cookie if(isset($_COOKIE['ID_my_site'])) //if there is, it logs you in and directes you to the members page { $email = $_COOKIE['ID_my_site']; $pass = $_COOKIE['Key_my_site']; $check = mysql_query("SELECT email, password FROM accounts WHERE email = '$email'")or die(mysql_error()); while($info = mysql_fetch_array( $check )) { if (@ $info['password'] != $pass) { } else { header("Location: home.php"); } } } //if the login form is submitted if (isset($_POST['submit'])) { // if form has been submitted // makes sure they filled it in if(!$_POST['email'] | !$_POST['password']) { die('You did not fill in a required field.'); } // checks it against the database if (!get_magic_quotes_gpc()) { $_POST['email'] = addslashes($_POST['email']); } $check = mysql_query("SELECT email,password FROM accounts WHERE email = '".$_POST['email']."'")or die(mysql_error()); //Gives error if user dosen't exist $check2 = mysql_num_rows($check); if ($check2 == 0) { die('That user does not exist in our database. <a href=add.php>Click Here to Register</a>'); } while($info = mysql_fetch_array( $check )) //gives error if the password is wrong if (@ $_POST['password'] != $info['password']) { die('Incorrect password, please try again'); } else { // if login is ok then we add a cookie $_POST['email'] = stripslashes($_POST['email']); $hour = time() + 3600; setcookie(ID_my_site, $_POST['email'], $hour); setcookie(Key_my_site, $_POST['password'], $hour); //then redirect them to the members area header("Location: home.php"); } } } else { // if they are not logged in ?> <?php } ?> home.php session_start(); if(!isset($_SESSION['email'])) { header('Location: login_test3.php'); die('<a href="login_test3.php">Login first!</a>'); } //Variables $_SESSION["email"] = $email; print $_SESSION['name']; UPDATE Just realized the existing code gets in to the home.php file but will not echo anything. But as soon as you hit refresh the session is gone.

  • Where is the root [closed]

    - by smwikipedia
    I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My question is: Where is this "big tree" located?

  • Why would gnu ld link order causes Signal 11 (SEGV) on startup?

    - by Benoit
    We are building a large application in C++ that includes the use of many (static) libraries. We have a problem where the application crashes on startup with a Signal 11, before we even reach main. After much debugging, we have observed that if we explicitly reference an object file so its link order is early, the program crashes on startup. If the file is referenced later (or not referenced at all), the program does not crash. To be clear, there is NO code invoked directly from this object file. However, as it is C++, there might be static objects that do get constructed (it's a CORBA IDL generated file). We use the -Wl,--start-group ... --end-group arguments to multi-pass link the symbols since the libraries are interdependent. Here is a representation of what I mean. This is what the linker's object file order is: Order 1 Order 2 Order 3 foo.o foo.o foo.o ... ... ... main.o main.o main.o crasher.o libA.o libA.o libA.o LibB.o LibB.o LibB.o LibC.o LibC.o LibC.o crasher.o Results: NO CRASH NO CRASH CRASH Does any one have an idea why the linkage order has an effect on the crash? It would be nice if we could force the crasher.o to link later, but we're really after an explanation. Also, is there a way to force the linker to place crasher.o towards the end? Just to add to the fun, in actuality, crasher.o is part of a Library in the --start/--end-group.

  • How to make dll referenced by ActiveX component accessible?

    - by sherpa
    I have an ActiveX component developed in C#. I'm referencing a dll which comes with other native dlls and it is loading them on the fly expecting them to be in the same folder (probably using Assembly.GetExecutingAssembly().Location but not sure, I don't have control over them). There is also one ini file which is also expected to be in the same folder. When I run the application as Windows form app, everything is fine, of course. But the trouble comes when I run it within Internet Explorer as the base directory is at the location of iexplore.exe. Obviously neither the dlls or the ini file can be found and many temporary working files outputted by the dlls are located in Internet Explorer folder. The workaround is to copy all ddls and ini file into the ie folder but that is not something I'd be happy about. What is the proper solution to this? Can I somehow set the base path for the ActiveX component?

  • SqlCE Flush Interval - Will the default setting lead to corruption?

    - by NormD
    SqlCE has a parameter set on the Connect String called Flush Interval. It is defined as: The interval time (in seconds) before all committed transactions are flushed to disk. If not specified, the default value is 10. I thought that a committed transaction, by definition, is a transaction that has been flushed to disk, specifically the database file. If a transaction is only stored in RAM then cannot the transaction be easily lost? I thought that transactions were first written to a log file and then applied to the database file itself, so perhaps this parameter could mean the time to wait until the transaction log is applied to the database file? I would have thought that this parameter should be 0.

  • Python: Open() using a variable

    - by nuustik
    Good day, I've ran into a problem with opening a file with randomly generated name in Python 2.6. import random random = random.randint(1,10) localfile = file("%s","wb") % random Then I get an error message about the last line TypeError: unsupported operand type(s) for %: 'file' and 'int' I just couldn't figure this out by myself nor with Google, but there has to be a cure for this, I believe. Thanks.

  • Can Perforce remove a version entry (like ClearCase Destroy)?

    - by Tim
    I submitted a Changelist in Perforce, but I forgot to remove a couple of files from the list first. I want to undo those changes. I understand that Perforce allows me to "rollback" -- but that just submits another change to the file, cluttering my branch. This is a file I did not intend to change at all. When I go to integrate back into the baseline, this file shows up as needing to be integrated (even though it's the same as what's on the baseline). In Clearcase, I had the ability to simply issue a "destroy" command on the specific version of the file, nuking it from the repository, as if had never been (yes, I realize this is scary from a revision control perspective - I understand the risks). Is there an equivalent command in Perforce? Or am I trying to do something expressly forbidden?

  • Cygwin make always processing target

    - by Michael
    However it happens only on Windows 7. On Windows XP once it built and intact, no more builds. I narrowed down the issue to one prerequisite - $(jar_target_dir). Here is part of the code # The location where the JAR file will be created. jar_target_dir := $(build_dir)/chrome # The main chrome JAR file. chrome_jar_file := $(jar_target_dir)/$(extension_name).jar # The root of the JAR sources. jar_source_root := chrome # The sources for the JAR file. jar_sources := bla #... some files, doesn't matter jar_sources_no_dir := $(subst $(jar_source_root)/,,$(jar_sources)) $(chrome_jar_file): $(jar_sources) $(jar_target_dir) @echo "Creating chrome JAR file." @cd $(jar_source_root); $(ZIP) ../$(chrome_jar_file) $(jar_sources_no_dir) @echo "Creating chrome JAR file. Done!" $(jar_target_dir): $(build_dir) echo "Creating jar target dir..." if [ ! -x $(jar_target_dir) ]; \ then \ mkdir $(jar_target_dir); \ fi $(build_dir): @if [ ! -x $(build_dir) ]; \ then \ mkdir $(build_dir); \ fi so if I just remove $(jar_target_dir) from $(chrome_jar_file) rule, it works fine.

  • Reading/Writing/Modifying a struct in C

    - by user1016401
    I am taking some information from a user (name, address, contact number) and store it in a struct. I then store this in a file which is opened in "r+" mode. I try reading it line by line and see if the entry I am trying to enter already exists, in which case I exit. Otherwise I append this entry at the end of the file. The problem is that when I open the file in "r+" mode, it gives me Segmentation fault! Here is the code: struct cust{ char *frstnam; char *lastnam; char *cntact; char *add; }; Now consider this function. I am passing a struct of information in this function. Its job is to check if this struct already exists else append it to end of file. void check(struct cust c) { struct cust cpy; FILE *f; f=fopen("Customer.txt","r+"); int num=0; if (f!= NULL){ while (!feof(f)) { num++; fread(&cpy,sizeof(struct cust),1,f); if ((cpy.frstnam==c.frstnam)&(cpy.lastnam==c.lastnam)&(cpy.cntact==c.cntact)&(cpy.add==c.add)) { printf("Hi %s %s. Nice to meet you again. You live at %s and your contact number is %s\n", cpy.frstnam,cpy.lastnam,cpy.add,cpy.cntact); return; } } fwrite(&c,sizeof(struct cust),1,f); fclose (f); } printf("number of lines read is %d\n",num); }

  • MySql Union not getting executed in a view

    - by aLL0i
    Hi, I am trying to create a view for a UNION of 2 select statements that I have created. The UNION is working fine when executed individually But the problem is only the 1st part of the UNION is getting executed when I am executing it as a view. The query I am using is as below SELECT DISTINCT products.pid AS id, products.pname AS name, products.p_desc AS description, products.p_loc AS location, products.p_uid AS userid, products.isaproduct AS whatisit FROM products UNION SELECT DISTINCT services.s_id AS id, services.s_name AS name, services.s_desc AS description, services.s_uid AS userid, services.s_location AS location, services.isaservice AS whatisit FROM services WHERE services.s_name The above works fine when i execute it separately. But when I use it as a view, it does not give me the results of the services part. Could someone please help me with this?

  • Can you write files in Chrome 8?

    - by greggory.hz
    I'm wondering if, with the new File API exposed in Chrome (I'm not concerned with cross-browser support at this time), it would be possible to write back to files opened via a file input. You can see an example of what I'm trying to accomplish here: http://www.grehz.com/ide. I know I can use server side scripts to dynamically create the files and allow the user to download them normally. I'm hoping that there's a way to accomplish this purely client side. I had read somewhere that you can write to files opened via a file input. I haven't been able to find any examples of this, though I have seen passing references to a FileWriter class. I would be completely not surprised if this wasn't possible though (it seems likely that there are security issues with this). Just looking for some guidance or resources. UPDATE: I was reading here: http://dev.w3.org/2009/dap/file-system/file-writer.html As I was playing around in Chrome, it looks like FileSaver and FileWriter are not implemented, but BlobBuilder is. I can call getBlob() on the BB object, is there any way I can then save that without FileSave or FileWriter?

  • How to change the elements in the page base on user who is logged in

    - by user225269
    Please give me an idea on how to display elements in a page depending on who is logged in. For example, a user or an administrator. I'm thinking of something like this but I get a parse error, what do I lack in this code?: <?php session_start(); if (!(isset($_SESSION['loginAdmin']) && $_SESSION['loginAdmin'] != '')) { header ("Location: loginam.php"); } if else (!(isset($_SESSION[['loginAdmin']) && $_SESSION['loginAdmin'] =='')) { ?> <?php include('head2.php'); ?> } <?php if (!(isset($_SESSION['login']) && $_SESSION['login'] != '')) { header ("Location: login.php"); } if else (!(isset($_SESSION[['login']) && $_SESSION['login'] =='')) { ?> <?php include('head3.php'); } ?> Please help
