  • Certain websites won't load with DHCP server

    - by Simon E
    Hi, I recently configured a server using Windows Server 2008 to take over from my router using DHCP Server. I disabled my router from assigning IPs too. All works well, except for certain sites that refuse to load e.g. "Firefox could not find www.amazon.co.uk" http://www.google.co.uk/ http://www.amazon.co.uk/ http://www.jobsite.co.uk/ I think it may have something to do with co.uk domain. If I reboot the server everything goes back to normal but of course thats not a good solution to do that every other day. Does anyone know of this problem or what it might be - I am very new to server technology.

  • IIS displaying page differently when localhost is used in URL vs. hostname

    - by maik
    I'm having (yet another) strange problem with IIS. When viewing an ASPX page I've designed on my local machine by browsing to http://localhost/page.aspx the page looks as expected (and looks the same in IE, Firefox and Chrome. If I change localhost to my_hostname the page is rendered with a disabled vertical scroll bar. The behavior was first noticed when I published my site to our live server and saw the same discrepancy. After beating my head against the wall I tried what I described above and was able to duplicate my "problem". So with that, I turn to you guys. This wouldn't really be an issue (save for the cross-browser inconsistency) except that this screws up an "absolute"ly positioned <div> moving it partway off the screen instead of being centered like it should be (and is when viewed any other way except in IE when the address is anything but localhost).

  • Sliding through divs at interval - jQuery

    - by phil
    Hey, I have a list of around 30 divs (see below.) and would like to hear any suggestions on the best way to rotate through them by sliding in one at the top and removing one from the bottom at a set time. Something like every 5-10 seconds. Also even though there are 30 on the page I would only like to show a list of 10 and have the rest show as mentioned. A great example would be www.foursquare.com and their recent activity section. I would like to do the same except with a predetermined amount of divs instead of real-time using ajax. Any suggestions or a bit of help pointing me in the right direction would be greatly appreciated. <div class="recent-questions"> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> <div class="recent-question"></div> </div> Thanks in advance for any help or thoughts!

  • Block upload of executable images (PHP)

    - by James Simpson
    It has come to my attention that a user has been trying to create an exploit through avatar image uploads. This was discovered when a user reported to me that they were getting a notice from their Norton Anti-virus saying "HTTP Suspicious Executable Image Download." This warning was referencing the user's avatar image. I don't think they had actually achieved anything in the way of stealing information or anything like that, but I assume it could be possible if the hole is left open long enough. I use PHP to upload the image files, and I check if the file being uploaded is a png, jpg, or gif.

  • httpURLConnection vs apache commons http

    - by Pablo Fernandez
    Hi everyone! I just wanted to know if any of you had any problems using java default HttpURLConnection class. Some kind of bug that made you switch to apache commons. Or is it just the (ugly) interface that class exposes that justifies the birth of 3rd party http lib? Disclosure: I heard some arguments against java.net having some serious problems, but I'm finding hard to believe that a class that is part of the java core distribution still has issues after several releases of the JDK

  • Rails each loop insert tag every 6 items?

    - by dustmoo
    Hello Stack Anon, I have X number of image objects that I need to loop through in a view and want to create a new div every 6 objects or so (for a gallery). I have looked at cycle but it seems to change every other record. Does anyone know of a way to insert code into a view every 6 times? I could probably do it with nested loops but I am kinda stumped on this one. Thanks!

  • Setting a form field's value during validation

    - by LaundroMat
    I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method).

  • 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?

  • Static variables in Java for a test oObject creator

    - by stevebot
    Hey, I have something like the following TestObjectCreator{ private static Person person; private static Company company; static { person = new Person() person.setName("Joe"); company = new Company(); company.setName("Apple"); } public Person createTestPerson(){ return person; } public Person createTestCompany(){ return company; } } By applying static{} what am I gaining? I assume the objects are singletons as a result. However, if I did the following: Person person = TestObjectCreator.createTestPerson(); person.setName("Jill"); Person person2 = TestObjectCreator.createTestPerson(); would person2 be named Jill or Joe?

  • "Share on LinkedIn" widget chokes on encoded spaces in url param

    - by David Droddy
    Does anyone know why I am not able to include my own, URL encoded URL params with URL encoded spaces? See the URL on my jsBin page constructed from LinkedIn's example--I have added (%3FnestedParam%3Done%20space) at the end of the "URL" value. THEN, if you remove the encoded space (%3FnestedParam%3DoneSpace) it works fine: Try it out: http://jsbin.com/acosa3/3 Thanks!

  • Using the stadard Java logging, is it possible to restart logs after a certain period?

    - by Fry
    I have some java code that will be running as an importer for data for a much larger project. The initial logging code was done with the java.util.logging classes, so I'd like to keep it if possible, but it seems to be a little inadequate now given he amount of data passing through the importer. Often times in the system, the importer will get data that the main system doesn't have information for or doesn't match the system's data so it is ignored but a message is written to the log about what information was dropped and why it wasn't imported. The problem is that this tends to grow in size very quickly, so we'd like to be able to start a fresh log daily or weekly. Does anybody have an idea if this can be done in the logging classes or would I have to switch to log4j or custom? Thanks for any help!

  • bash completion processing gone bad, how to debug?

    - by msw
    It all started with a simple alias gv='gvim --remote-quiet' and now gv Space Tab gives nothing where it normally should give filenames. Oddly, alias gvi='gvim --remote-quiet' works as expected. I clearly have a workaround, but I'd like to know what is catching my gv for special processing. compopt is no help as gv shares the same settings as ls which does filename completion correctly. $compopt gv compopt +o bashdefault +o default +o dirnames -o filenames +o nospace +o plusdirs gv $ compopt ls compopt +o bashdefault +o default +o dirnames -o filenames +o nospace +o plusdirs ls The complete command is slightly more helpful but it doesn't tell me why my two characters got singled out for alteration: $ complete -p gv complete -o filenames -F _filedir_xspec gv $ complete -p ls complete -o filenames -F _longopt ls $ complete -p echo bash: complete: echo: no completion specification $ alias gvi='gvim --remote-silent' msw@tallguy:~/.gnupg$ complete -p gvi bash: complete: gvi: no completion specification Where did complete -o filenames -F _filedir_xpec gv come from?

  • How to add http headers in suds 0.3.6?

    - by Esabe
    Hi everyone, I have an application in python 2.5 which sends data through suds 0.3.6. The problem is that the data contains non-ascii characters, so I need the following header to exist in the soap message: Content-Type="text/html; charset="utf-8" and the header that exists in the SOAP message is just: Content-Type="text/html" I know that it is fixed in suds 0.4, but it requires Python2.6 and I NEED Python2.5 because I use CentOS and it needs that version. So the question is: How could I change or add new HTTP headers to a SOAP message?

  • Win32 script environment for testing http redirects?

    - by Anders Lindahl
    The past few days I've been working with setting up an Apache server on Windows. The server is supposed to host several .htaccess files, each redirecting (or, in some cases, proxying) to different hosts. I want to create tests for these redirectons, and the solution I'm currently considering is a CGI script running on the same server, sending GET requests to it and verifying that it gets the correct redirection headers back. A scripting solution (vscript/jscript) seems worth exploring, but so far I've only managed to rule out Microsoft.XMLHTTP because it follows the redirect "behind the scenes". Are there any libraries or other solutions already present on a reasonably standard Windows Server that can do this kind of low-level HTTP work? If not, any other suggestions of simple environments to set up for verifying redirects?

  • KML Layers Cursor CSS - Google Maps API v3

    - by Douglas
    I've run into a small problem with the semi-new KML Overlay functionality with Google Maps API v3, wherein while I am able to use "suppressInfoWindows: true;", the cursor still appears as though the overlay(s) are clickable. Is there a way at this time to change the css on the overlay(s) so that the cursor is the default cursor, so that they are purely visual, and don't confuse the user? The current demo version can be viewed here: http://dougglover.com/samples/finalProduct/ Any assistance is greatly appreciated.

  • Allowed unicode characters in IDN host labels

    - by Roland Franssen
    Hi all, Im currently working on a "proper" URI validator and currently it all comes down to hostname validation, the rest isnt that tricky. Im stuck at IDN hostname labels (e.g. containing unicode; possible punycode encoded strings have been decoded at this point). My first idea was basicly a regex for TLD's not supporting IDN and one for those who do (http://www.mozilla.org/projects/security/tld-idn-policy-list.html (?)). Respectively; ^[a-zA-Z0-9-]+$ and ^[a-zA-Z0-9-\p{L}]+$ However this is not an ideal situation, since every IDN registrar can decide which characters to allow and which not. What im looking for is a proper, consistent, up2date data table of unicode characters allowed in various TLD's; im getting this idea i have to find all the data myself at russian and chinese registry sites (which is quite difficult). So before spitting down the web.. i wondered is there such a list? Or are there better approaches, best/common practices etc? (I want the validation to be as strict as possible.) Any help is welcome! // Roland

  • Create Macro With Several Variables

    - by Daniel
    I have several worksheets with similar code, so I'd like to turn it into a macro. My only problem is that there are several variables. So at certain points the code looks like this: Dim Msg_1 As String Dim Msg_2 As String Public Sub ListBox1_LostFocus() ListBox1.Height = 15 With ListBox1 Msg1 = "'" For i = 0 To .ListCount - 1 If .Selected(i) Then Msg1 = Msg1 & .List(i) & "','" End If Next i End With Msg1 = Left(Msg1, Len(Msg1) - 2) Sheets("Sheet1").Range("R3", "R3") = Msg1 End Sub and so on. How can I pass in a new value for Msg1, Msg2, Msg3 for each worksheet?
