  • IE Print CSS and spanning page breaks

    - by DA
    I've been working on trying to fix an issue with print CSS and IE where things would disappear when printing in landscape mode. It appears the issue is that the element I'm trying to print (a large DIV with content inside it) spans two pages when put into landscape mode. What is happening is when the element spans two pages, the first page is blank, and the second page is printing what would normally be left over from the first page. I think it's related to contained floats: wrapper div floated div1 floated div2 If I set the two nested divs to float: none in the print CSS file, then IE will print them, albeit not in the layout we'd like. Before I spend another hour on this, anyone know what, specifically, is the issue here and if there's a known workaround?

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks

  • How to launch a mac application without a terminal window.

    - by KPexEA
    I've written an open-source c++ application and it works fine on Windows and Linux, I finally got a Mac Mini (with 10.5.8) so I've just been testing the Mac version. My application works fine when running it from inside a terminal window and typing ./appname , but if instead I double click on it from the finder, then it opens a termnial window first and then runs my app but it doesn't seem to set the working directory to the correct location so my app dies. How do I make my app so when it launches by being double clicked on it doesn't open a terminal window first and how can I have the current directory set to the apps location automatically?

  • Incrmenting a Cookies with PHP (Beginner Question)

    - by BandonRandon
    Hello, I have used sessions before but never cookies. I would like to use cookies for two reasons: 1) it's something new to learn 2) I would like to have the cookie expire in an hour or so (i know in the code example it expires in 40 sec) I am trying to write a basic if statement that if($counter=="1") { //do this second } elseif ($counter >="2") { //do this every time after the first and second } else {// this is the first action as counter is zero } Here is the code I'm using to set the cookie: // if cookie doesnt exsist, set the default if(!isset($_COOKIE["counter_cookie"])) { $counter = setcookie("counter_cookie", 0 ,time()+40); } // increment it $counter++; // save it setcookie("counter_cookie", $counter,time()+40); $counter = $_COOKIE["counter_cookie"]; The problem is that the counter will be set from 0 to 1 but won't be set from 1 to 2 and so on. Any help would be great I know this is a really simple stupid question :| Thanks!

  • Set Caret position with JTextArea in JScrollPane

    - by Albinoswordfish
    Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all. I'm using the basic function setCaretPosition() for the JTextArea Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition() Edit: It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?

  • In a graph, how to find the nearest node to a group of nodes?

    - by Nikola
    Hello, I have an undirected, unweighted graph, which doesn't have to be planar. I also have a subset of graph's nodes (true subset) and I need to find a node not belonging to the subset, with minimum sum of distances to all nodes in the subset. So far, I have implemented breath-first search starting from each node in the subset, and the intersection that occurs first is the node I am looking for. Unfortunately, it is running too slow since the graph contains a large number of nodes. Any advice or comment will be appreciated. Thank you, Nikola

  • grdb not working variables

    - by stupid_idiot
    hi, i know this is kinda retarded but I just can't figure it out. I'm debugging this: xor eax,eax mov ah,[var1] mov al,[var2] call addition stop: jmp stop var1: db 5 var2: db 6 addition: add ah,al ret the numbers that I find on addresses var1 and var2 are 0x0E and 0x07. I know it's not segmented, but that ain't reason for it to do such escapades, because the addition call works just fine. Could you please explain to me where is my mistake? I see the problem, dunno how to fix it yet though. The thing is, for some reason the instruction pointer starts at 0x100 and all the segment registers at 0x1628. To address the instruction the used combination is i guess [cs:ip] (one of the segment registers and the instruction pointer for sure). The offset to var1 is 0x10 (probably because from the begining of the code it's the 0x10th byte in order), i tried to examine the memory and what i got was: 1628:100 8 bytes 1628:108 8 bytes 1628:110 <- wtf? (assume another 8 bytes) 1628:118 ... whatever tricks are there in the memory [cs:var1] points somewhere else than in my code, which is probably where the label .data would usually address ds.... probably.. i don't know what is supposed to be at 1628:10 ok, i found out what caused the assness and wasted me whole fuckin day. the behaviour described above is just correct, the code is fully functional. what i didn't know is that grdb debugger for some reason sets the begining address to 0x100... the sollution is to insert the directive ORG 0x100 on the first line and that's the whole thing. the code was working because instruction pointer has the right address to first instruction and goes one by one, but your assembler doesn't know what effective address will be your program stored at so it pretty much remains relative to first line of the code which means all the variables (if not using label for data section) will remain pointing as if it started at 0x0. which of course wouldn't work with DOS. and grdb apparently emulates some DOS features... sry for the language, thx everyone for effort, hope this will spare someone's time if having the same problem... heheh.. at least now i know the reason why to use .data section :))))

  • iPhone post-processing with a single FBO with Opengl ES 2.0?

    - by Jing
    I am trying to implement post-processing (blur, bloom, etc.) on the iPhone using OpenGL ES 2.0. I am running into some issues. When rendering during my second rendering step, I end up drawing a completely black quad to the screen instead of the scene (it appears that the texture data is missing) so I am wondering if the cause is using a single FBO. Is it incorrect to use a single FBO in the following fashion? For the first pass (regular scene rendering), I attach a texture as COLOR_ATTACHMENT_0 and render to a texture. glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, texturebuffer, 0) For the second pass (post-processing), I attach the color renderbuffer to COLOR_ATTACHMENT_0 glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorRenderbuffer) Then use the texture from the first pass for rendering as a quad on the screen.

  • X11 and ARGB visuals: does DefaultDepth() never return 32?

    - by Andy
    Hi, I'm establishing a connection to the X server like this: display = XOpenDisplay(NULL); screen = DefaultScreen(display); depth = DefaultDepth(display, screen); I'm wondering now why "depth" is always set to 24. I would expect that it is only 24 when compositing is turned off, but in fact, it is still 24 even when I turn on compositing. So in order to get a 32-bit ARGB visual I need to call XGetVisualInfo() first with depth set explicitly to 32. Now to my question: Will DefaultDepth() generally never return more than 24 or is it just on my system? (my graphics board is somewhat dated...). I know that it could return 15, 16 or even 8 for a CLUT display but can it return 32? Or do I always have to use XGetVisualInfo() first to get a ARGB 32-bit visual? Thanks, Andy

    what is the next best thing to use when you want to select the next li item, but not the one that has someClassName. The not selector returns an empty array! or is this a case off using filter? <li class="first">pickle</> <li class="someClassName">tomato</li> <li>chicken</> <li>cocosnut</> var current = $('ul.items li.first'); var next = current.next(':not(li.someClassName)'); thanks, Richard

  • MonoRail - Clearing value on edit form submission doesn't trigger validation

    - by Justin
    Hey, In a MonoRail app I have an add/edit view. On add if I don't pick a value for a dropdown I get a validation error and am forced to pick a value. However, if I then edit that same item and reset the dropdown back to the first item ("Select an Item", "0"), it saves and doesn't say it was invalid. Debugging the entity sent back to the server, I can see that it's sending the original value for the dropdown instead of the new value of "0". What's going on here? The first thing I would expect is that it would trigger the validation since the dropdown value isn't set. The second thing I would expect is that it would send the new value I send, not the original. It does send the new value if I change it to another value, but it's as if it has internal logic that says - "I'm updating this entity and a new value was not passed, just don't change the entity value." Thanks, Justin

  • problem with HttpWebRequest.GetResponse perfomance in multithread applcation

    - by Nikita
    I have very bad perfomance of HttpWebRequest.GetResponse method when it is called from different thread for different URLs. For example if we have one thread and execute url1 it requires 3sec. If we ececute url1 and url2 in parallet it requires 10sec, first request ended after 8sec and second after 10sec. If we exutet 10 URLs url1, url2, ... url0 it requires 1min 4 sec!!! first request ended after 50 secs! I use GetResponse method. I tried te set DefaultConnectionLimit but it doesn't help. If use BeginGetRequest/EndGetResponse methods it works very fast but only if this methods called from one thread. If from different it is also very slowly. I need to execute Http requests from many threads at one time. ?an anyone ever encountered such a problem? Thank you for any suggestions.

  • does the condition after && always get evaluated

    - by brett
    I have this if statement that tests for the 2 conditions below. The second one is a function `goodToGo() so I want to call it unless the first condition is already true $value = 2239; if ($value < 2000 && goodToGo($value)){ //do stuff } function goodToGo($value){ $ret = //some processing of the value return $ret; } My question is about the 2 if conditions $value < 2000 && goodToGo($value). Do they both get evaluated or does the second one only get evaluated when the first one is true? In other words, are the following 2 blocks the same? if($value < 2000 && goodToGo($value)) { //stuff to do } if($value < 2000) { if (goodToGo($value)){ //stuff to do } }

  • How to enable/create elements on the fly

    - by Simon S
    Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

  • PDF Viewer Showing Last Page...

    - by steve
    I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. No problems there. The weird part... The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?" Environment particulars: asp.net 3.5 vb, websupergoo's abcpdf.net pro 7 (assembly that creates the pdf file), Windows 2008 Server, IIS7 Thanks

  • How do I create a MessageBox in C# ?

    - by Nick Stinemates
    I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

  • double authentication issue on IIS / Report Server (SQL server 2008)

    - by Vinzz
    Hi, On a 2003 server box, with SQL server 2008 installed (ReportServer deployed in IIS mode), I've got a virtual directory within IIS with it's security set to 'windows authentication', with the following html code: <body> <h1>test</h1> <iframe src="/reportserver" witdh="50%" height="50%" /> </body> From the outside, I've got a first login/pwd box displayed to access the html code, then a second one to display the content of the iframe. On the same type of server, but with SQL Server 2005, I don't have this issue (i.e. only one login box). My thought is that the first token should give acces to both the page and the iframe, isn't it? Any hints on how to setup the reportserver to fix this? thanks.

  • jQuery .live() not working.

    - by Silvio Iannone
    Hi there, my actual problem is that .live() jQuery method is not working. This si the code where i use it: jQuery.fn.sb_animateMenuItem = function() { var mousehoverColor = '#0089F7'; var duration = 250; return this.each(function() { var originalColor = $(this).css('background-color'); $(this).live('mouseover', function() { this.style.cursor = 'pointer'; $(this).animate().stop(); $(this).animate( { backgroundColor: mousehoverColor }, duration); }); $(this).live('mouseout', function() { this.style.cursor = 'default'; $(this).animate( { backgroundColor: originalColor }, duration); }); }); }; This snipped is used i another page in this way: <script type="text/javascript" src="ui/js/jquery-1.4.2.js"></script> <script type="text/javascript" src="ui/js/jquery-ui-1.8.1.custom.min.js"></script> <script type="text/javascript" src="ui/js/color.js"></script> <script type="text/javascript" src="engine/js/tiny_mce/tiny_mce.js"></script> <script type="text/javascript" src="ui/js/ui.js"></script> <script type="text/javascript"> // UI effects $(document).ready(function() { $('button').sb_animateButton(); $('input').sb_animateInput(); $('.top_menu_item').sb_animateMenuItem(); $('.top_menu_item_right').sb_animateMenuItem(); $('.left_menu_item').sb_animateMenuItem(); }); </script> Since my site uses AJAX requests i used the .live method in the first snippet, but when i load the page the effects are not applied the the button/input... tags. If i remove the .live method and use the 'normal' way, ui effects defined in the first snipped are applied but only the the elements loaded before any AJAX request. The elements loaded after the ajax request are not affected by first snippet (though they have the same selector). Thanks for helping.

  • Chain dynamically created dropdowns with JQuery

    - by ricardocasares
    I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

  • Communicate multiple times with a process without breaking the pipe?

    - by Manux
    Hello, it's not the first time I'm having this problem and its really bugging me. Whenever I open a pipe using the Python subprocess module, I can only communicate with it once, as the documentation specifies: Read data from stdout and stderr, until end-of-file is reached proc = sub.Popen("psql -h darwin -d main_db".split(),stdin=sub.PIPE,stdout=sub.PIPE) print proc.communicate("select a,b,result from experiment_1412;\n")[0] print proc.communicate("select theta,zeta,result from experiment_2099\n")[0] The problem here is that the second time, Python isn't happy. Indeed, he decided to close the file after the first communicate: Traceback (most recent call last): File "a.py", line 30, in <module> print proc.communicate("select theta,zeta,result from experiment_2099\n")[0] File "/usr/lib64/python2.5/subprocess.py", line 667, in communicate return self._communicate(input) File "/usr/lib64/python2.5/subprocess.py", line 1124, in _communicate self.stdin.flush() ValueError: I/O operation on closed file So... multiple communications aren't allowed? I hope not ;) Please enlighten me.

  • Any better algorithm possible here?

    - by Cupidvogel
    I am trying to solve this problem in Python. Noting that only the first kiss requires the alternation, any kiss that is not a part of the chain due to the first kiss can very well have a hug on the 2nd next person, this is the code I have come up with. This is just a simple mathematical calculation, no looping, no iteration, nothing. But still I am getting a timed-out message. Any means to optimize it? import psyco psyco.full() testcase = int(raw_input()) for i in xrange(0,testcase): n = int(raw_input()) if n%2: m = n/2; ans = 2 + 4*(2**m-1); ans = ans%1000000007; print ans else: m = n/2 - 1 ans = 2 + 2**(n/2) + 4*(2**m-1); ans = ans%1000000007 print ans
