  • File permissions question

    - by Camran
    If I need a php-page to have access to upload images and move images from a folder on the server, what permissions would I set on the folder then? I know we have "Owner", "Group", and "Others". But what does the server (or the php-code itself) count as? Owner? Also, would I need to set the php-page with the upload script with some specific permissions to be able to upload the files? Is it execute permissions? Thanks

How do I get two response, then two html page, starting from the same request? is a thing possible? The first response should continue to do what he does now, while the second would appear to make a popup window to save an image. There are easier ways to achieve the same result? Many thanks in advance

  • 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

  • BlackBerry - Handle and translate messages (sms/email/pim/pin)?

    - by humble coffee
    Does the native Blackberry API allow for the modification of any messaging interface? For example, I'd like to be able to build an app that added a button at the bottom of a received message which says 'translate this'. I've heard that this kind of thing is possible using J2ME plus the native BlackBerry API. Can this be done for all kinds of messages, eg SMS, email and BB messaging? The translation aspect is not relevant, it just provides the context for the kind of feature I'm after.

  • different brainpoolP521r1 parameters for flexiProvider. Why?

    - by user182846
    I am trying to generate ECC public private key pairs using flexiProvider. I have noticed that values for parameters like p and q are different in brainpoolP521r1 of flexiProvider than those which are specified in many sites. Values specified are Q= AADD.... but what I get is Q=8948... Any idea why flexiProvider does not use specified values and whether having different values is affectes security. I am new to ECC. Any help will be greatly appreciated.

  • Eclipse debug - line: not available

    - by Mike
    I can't seem to find anything on google telling me why this might be and what the resolution is. I'm Stepping through third party code (that I have the source for) and would really like to see the current line being executed... Looking at javac compile flags, I see the -g:none flag. If this flag is set, would this be enough to explain why I'm not able to see line numbers? If so, why would someone do this, are there performance implications? Do I need to recompile the jar myself to attach the missing debug info (if possible)? Thanks!

  • Alert Box Methods

    - by Vecta
    I just need a little advice on what may be the best method for handling my situation. I'm in need of placing three buttons in the sidebar of the website I maintain. The website is massive and hard to handle. Currently, it's all HTML files (there are over 10,000 of them believe it or not). We're transitioning to a database website so I don't want to make any sweeping changes that are site-wide, as they may just be scrapped in our re-design process in coming months. However, these buttons are for an application process. When you click on them, an alert box will need to pop up to give you a bit of information and they either allow you to cancel the action or proceed. The buttons are currently located in the left nav which is included on every page of the website. Would it be possible to accomplish this using JS or jQuery? I'd be unable to easily add scripts into the tags on all of the applicable pages, but I'd like to avoid the browser driven "http://www...Says: blah blah" message if possible. Any insight is greatly appreciated! Thank you!

  • Criteria: search for two different entity classes...

    - by RoCMe
    Hi! I have a "super entity" SuperEntity and three entities ChildEntity1, ..., ChildEntity3 which extends the super class. It's easy to search for all entities in the database, i.e. we could use session.createCriteria(SuperEntity.class); It's no problem to search for one specific entity type, too, just replace the SuperEntity with any of the children to look for entities of that type. But I have a problem when allowing 'multiple choice' for the types. I.e., it could be neccessary to search all entities of type 1 and 2, but not of type 3. A first idea was to create two independent queries and join the results in a final list - but that would destroy the paging which uses offset and limit functionality of the database... Is there a possibility in Criteria to join two different queries in one single result list? Kind regards, RoCMe

  • timing response speed of serial device

    - by dario frongi
    I comunicate with a serial device via bluetooth. i send it pid and it responds to me with a data response. i comunicate with him with serial comunicatione one request-response. i want to measure how many response i receive in one second. i think that i have to know the moment when i do the request and the moment whene i receive the response and do the difference. The result(called delta) is the time-to response of device. in the end i have to do 1000ms/delta. how can calculate it ?

  • How to determine page generation time with Struts 2 ?

    - by Samuel_xL
    I'm using Struts 2 and I'd like to determine the page generation time without an external profiler. I can easily profile the actions execute() method, but I don't know how to include the time spent before (in dispatchers, interceptors...) and after (time taken by the servlet corresponding to the view ("jsp time")). Is there simple way to do this ? And if there isn't, how could I, at least, profile the "jsp time" (maybe a tag I'm not aware of ?) ? I think it would be accurate enough to just take in account action time + jsp time. Thanks.

  • Persisting Serializable Objects in Hibernate

    - by VeeArr
    I am attempting to persist objects that contain some large Serializable types. I want Hibernate to automatically generate my DDL (using Hibernate annotations). For the most part, this works, but the default database column type used by Hibernate when persisting these types is tinyblob. Unfortunately, this causes crashes when attempting to persist my class, because these types will not fit within the length of tinyblob. However, if I manually set the type (using @Column(columnDefinition="longblob")), it works fine. Is there any way to make the default binary type longblob instead of tinyblob, so that I don't need to manually specify the @Column annotation on each field?
