• CSS Rule Priorities

  - by Antilogic

  Given the following mark-up... <div id="Header"> <a href="#" class="Highlight">foo</a> </div> And the following stylesheet... /******************Exceptions******************/ #Footer, #Header, #Footer a, #Header a { color: #f8f8f8; } /******************Classes******************/ .Highlight, a.Highlight { color: #B1D355; } .Notification, a.Notification { color: Red; } Why is my link still off-white (F8F8F8) rather than green (B1D355)? Shouldn't using the class Highlight override the color settings for Header and Footer since it comes after their declarations?

• Can I improve my validation?

  - by Qmal

  So I want to validate my form using jQuery, this is how I imagine it and it works, but is the best method of doing it and maybe I can do it more effective with less code? <script type="text/javascript"> $(document).ready(function() { $("#frmCatAdd").submit(function() { var name = $("#edtName").val(); if (name == "") $("#edtName").css("border", "1px solid red") else $("#frmCatAdd").submit(); return false; }); }); </script>

• CSS Question - Any way to set (eg. a font-size) to a group of styles, by linking the style to anothe

  - by Joe

  .small_fonts{ font-size:10px; } .fonts_blue{ color:blue; } .fonts_red{ color:red; } .fonts_green{ color:green; } Any way to apply "small_fonts" to each of the "fonts_blue, _red, _green" w/o doing this: .fonts_blue, fonts_red, fonts_green { font-size:10px; } I am just trying to update my css to be more organized. I realised I don't need to define the font-size for each of the "small" fonts. When adding the class btw... I know you can do this: class="small_fonts fonts_blue" ~ however I'm talking about combining within the css stylesheet

• How to place some text over the DIV without breaking hover area of this DIV?

  - by Andr

  I'm total noob with CSS and it looks like hell =/ I have absolute positioned DIV and I handle mouse events over this DIV with JS like this: <div style='position: absolute; left: 0px; width:50px; height: 50px;' onmouseover='this.style.border="2px solid red"' onmouseout='this.style.border="1px solid black"'> </div> <div style='position: absolute;'>SOME TEXT</div> I need to place some text over this DIV and over the few same DIVs, but if I place any element over this DIV onMouseOut event is firing when mouse cursor switch to text. Tag with text can't be inside the DIV. Playing with z-index didn`t help. My browser is IE8.

• Excel Interop: Fastest way to change color of portions of text in a huge range of cells

  - by Kyopaxa

  There some articles about the fastest way to write data using Excel interop assigning directly an Array of data to the value of the range. Like: string[,] multidimensionalArrayData = new string[200, 3]; // (...) Fill multidimensionalArrayData with your data dataSheet.Range["A1:C200"].Value = multidimensionalArrayData; There are also some articles about how to change the Font color of a specific portion of text, for example (VB this time): With ActiveCell.Characters(Start:=3, Length:=3).Font .Name = "Arial" .FontStyle = "Regular" .Size = 10 .Color = "Red" .ThemeFont = xlThemeFontNone End With The question now is, what would be the fastest way to change the color of specific portions of text for thousands of cells? Currently, in my C# code, I have to do it cell by cell, with a horrible performance hit. Is there a way to fill an array of 'Characters' objects in C# and pass that array to a range in one go? Any other solutions?

• How to change a table row color when clicked and back to what it was originally when another row clicked?

  - by user1277222

  As the title explains, I wish to change the color of a row when it is clicked then revert the color when another is clicked, however still change the color of the newly clicked row. A resolution in JQuery would be much appreciated. I just can't crack this one. What I have so far but it's not working for me. function loadjob(jobIDincoming, currentID){ $("#joblistingDetail").load('jobview.php' , {jobID: jobIDincoming}).hide().fadeIn('100'); var last = new Array(); last.push(currentID); $(last[last.length-1]).closest('tr').css('background-color', 'white'); $(currentID).closest('tr').css('background-color', 'red');};

• How animate stacking divs in javascript/css?

  - by Teiviere

  Say I have 2 divs with the same CSS class that are stacked on top of each other: div { width:100px; height: 100px; background: red; } How do I make it so that when I click a button at the top of the page, a new div is created from off the screen at the bottom and moves upwards stopping where the 2nd div is.. When the button is clicked again, a 4th div moves in from the bottom of the screen and stops where the 3rd div is... etc creating a "stacked" divs effect? I know about position:fixed and adjusting values for top, but I am not sure how to dynamically calculate where to stop the animation to achieve this effect.

• incompatible types in java

  Should I point out that I am a begginer at this? double averageMonthlyTemp() { double[] amt = new double[52]; int sum = 0; int index = 0; for (int i = 0; i < temp.length - 1; i = i + 7) { //where temp is an existiing //previously initialized array //of 365 elements, form 0 to 364 for (int j = 0; j < 7; j++) { sum = sum + temp[i + j]; if (j % 7 == 6) { double average = ((double) sum) / 7; amt[index] = average; index++; sum = (int) 0; } } } return amt; } When I try to compile, I get an "incompatible types" error, with the "amt" at return amt marked in red. Does somebody know why?

• How do I get the namespace prefix?

  - by 1.21 gigawatts

  Is there a way to get the namespace prefix from a class or class instance (an object not XML)? For example, in MXML you could declare something as s:Button or local:MyComponent. Is there some call or approach that will return the "s" or "local" value when given the object? For example, if I have the class TextInput and I wanted to show the style inheritance at runtime I could do something like this: s|TextInput { fontFamily:Arial; } s|TextArea#myTextArea { color:red; } local|MyComponent.myBoldStyle { fontWeight: bold; }

• Permission denied after image upload

  - by moustafa

  I've got a image upload script that works on my Apache on IIS development server, but on the Apache Lunix live server, although the images are uploaded correctly and the MySQL database is updated correctly, I can't view the images. Viewing the HTML source, checking both the FTP files and the database values, all look OK. But the image doesn't show, just the white box with the red cross in the corner. If I try to copy the shortcut of the image and open it in a seperate window, I get the following: I'm not sure what to try next, it seems strange that the files/database/source look good but it just won't show! I've tried both $HTTP_POST_FILES and $_FILES to upload the images, but both have the same result. If anyone has any ideas, please help!

• How to retrieve CSS style object by CSS class name?

  - by Chir

  Hi, Is it possible to get all properties of a css class associated with an element? e.g. .hightligh { font-weight: bold; border: 1px solid red; padding-top:10px; } Lets say the css class "hightlight" is assigned to div element <div class='highlight'></div> Now using JavaScript, I need to iterate through all style properties of css class "highlight" associated with the div element. Basically, I want to treat it as a JavaScript object whose properties can be accessed using iterator or for loop. Thanks in advance

• two div boxes [1st float, 2nd clear], margin on 2nd doesn't seem to push off first

  - by mach77

  In the code below I have two div boxes. The first is float:left, the second has clear:left so that it sits below the first. My question is why does margin-top:20px not push off the first div? <head> <style> div { width:100px; height:100px; background-color:green; } #box1 { float:left; } #box2 { background-color:red; clear:left; margin-top:20px; } </style> </head> <body> <div id="box1"></div> <div id="box2"></div> </body>

• SVN / Tortoise SVN - Cannot checkout, Access is denied

  - by Shevek

  We are having a strange problem with our SVN repository One particular project is failing to check out on some dev's workstations. The error is: svn: E720005: Can't open file 'C:\path\.svn\pristine\4e\4e576fad0f625706379863e6051aac33097dbee0.svn-base': Access is denied. All branches, tags and trunk fail at the same point of checkout Other projects in the repository can be checked out fine One of our devs can check out the problem project fine. We have tried 3 different versions of TortoiseSVN (both UI and command line) and another build of win32svn. The one who can check out is using the same client version as one who cannot. Any ideas?

• "getpt failed: No such file or directory" when opening a terminal through VNC

  - by Michael

  I am running Debian Wheezy on my server, and have just installed a VNC server and Xfce. I have come across a problem: whenever I open a terminal emulator through VNC, I get an error box with this message: Failed to execute child. getpt failed: No such file or directory. This happens with every terminal I try to run. I can still run commands through SSH, however. It's just the terminal that won't open. Does anyone have any suggestions? /etc/fstab: proc /proc proc defaults 0 0 none /dev/pts devpts rw 0 0

• Why do I see "Operation was denied because the current credentials do not have the appropriate privileges" when trying to chsh?

  - by alecmce

  I'm setting up a new dev Macbook Pro, and trying to replace bash with zsh. I installed zsh and can run it to change shell in a session. When I use sudo chsh -s /bin/zsh username I get the error message: chsh: Operation was denied because the current credentials do not have the appropriate privileges. Operation was denied because the current credentials do not have the appropriate privileges. AFAIK I have admin privileges on the machine. What could be causing this?

• OpenIndiana installation hangs at 2% - Preparing disk for OpenIndiana installation

  - by Chris S

  I've been trying to install OpenIndiana on an HP DL320 G6 for a while now. I've got a 16GB HP SDHC card in the onboard slot and a SATA CD-Rom with oi-dev-151a-text-x86.iso burnt to a disc. Installation seems to progress fine until I get to the actual installation portion. The SD card is picked up as a USB Disk. All the other configuration options are very 'normal' (there really aren't many options to begin with). Automatic NIC configuration. The installer starts "Installing OpenIndiana", does a few steps, then gets to "Preparing disk for OpenIndiana installation" at 2%; and just sits there. I've let it sit for half an hour now ans still no progress. How can I get past this issue? PS I'm not terribly familiar with OpenSolaris, but am with FreeBSD and *nix CLIs in general.

• DB2 insert performance - How to measure

  - by svrist

  [From stackoverflow] Im trying to find a way to speedup my inserts to a DB2 9.7.1 (ubuntu linux) Im watching vmstat and trying to gather some statistics via the db2 get snapshot commands but im not able to figure out which numbers im looking for to be able to see where the trouble is. I've read lits of stuff like http://www.eggheadcafe.com/software/aspnet/35692526/question-multiple-row-in.aspx, and http://www.ibm.com/developerworks/data/library/tips/dm-0403wilkins/ and tricks like ALTER TABLE lalala APPEND ON works somewhat (the difference between a dd if=/dev/zero and insert is still a factor 10) but I would like to be able to find the counters or other performance indicators that actually show why it makes sense to use those tricks. For example: What is the metric called that shows me that it is buffer pages allocation (FSCR stuff) that is the problem Where do I see that the insert time is hampered by clustered indexes? I find db2top very useful but im still searching for more direct view of "this is your bottleneck" methods

• IE8 Developer Tools won't open

  - by Dave

  Just installed IE8 on WinXP. Trying to use the Dev Tools but, clicking on the menu item or hitting F12 doesn't do anything. I can see the option in the tools menu, just can't use it. I've checked to make sure it wasn't opening minimized or off screen and I've checked the registry settings used to disable them. Those registry keys don't even exists. Suggestions? I was going to reinstall, but, thought I'd check here first.

• Can the Dell PowerEdge T320 boot from a USB stick in hard drive emulation mode?

  - by Icydog

  I am trying to install FreeNAS on a Dell PowerEdge T320. I've followed the instructions here (http://doc.freenas.org/index.php/Burning_an_IMG_File) to write the .img file to four different USB sticks with dd if=FreeNAS-9.2.1.5-RELEASE-x64.img of=/dev/sde, but I can't boot off of any of them. When I try to boot, I get the following screen: F1 FreeBSD F2 FreeBSD F3 Drive 0 Then it auto-selects F1 and either prints # about once a second forever, or it sits with a blinking cursor doing nothing. Forum posts and the wiki page linked above say to set the USB boot emulation mode to hard disk (as opposed to auto or CD/DVD/floppy), and older Dell PowerEdge models including the T310 have this option in the BIOS settings, but I cannot find it on the T320 with the latest BIOS 2.1.2. I have even tried writing the USB image to a USB hard disk, but with the same lack of success. Has anyone been able to find this USB boot setting on a T320, or been able to boot FreeNAS/FreeBSD from USB in some other way on a T320?

• IIS7 Network Bios command limit and disabling file change notifications.

  - by meandmycode

  Having experienced IIS for many years I've hit this error various times in the past, and understand it, the gist being IIS is attempting to setup so many file change notifications over a UNC share that it is hitting a specified limit of active commands. However, whilst I understand this is a registry change on the endpoints, in our internal network we're starting to hit this when running certain domains that have large content (and the content is then stored out of source control and instead on a dumb network store). Given this is a testing environment and rather than changing registry settings (which may not even work for client (dev) machines that run Vista IIS), I'd like to stop IIS setting up all these file change notifications. Is this possible to do on a per site basis? additionally the configuration can't be in the web.config, if this means having to disable FCN's for the entire IIS server this would be preferred. Thanks in advance.

• NFS to NFS mount

  - by dude

  I have a machine that I need to bridge NFS files to. Can I mount an NFS directory on machine2 from machine1 and then mount the mounted NFS directory on machine2 on machine3 via NFS? Do you see any problems with that? I am basically bridging some subnet domains this way, in a certain fashion. My development machine is on a different and separate (unbridged) than where I would like to use the files, and I would like this machine1(dev machine) - machine2(passthrough machine) - machine3(test machine) connection. And no there is no way to move the test machine as it's a chassis :) and it's two buildings away.

• How do I mount an EBS root volume to a windows instance in Amazon EC2

  - by Kyle

  So basically, I created a large windows server for development, and then I created a micro windows server for production. I set up everything how I wanted it on my development server, and then i unmounted the drives, and mounted them to my micro server. Now I'm trying to get back into my large windows development server, and I'm getting the error. Invalid value 'i-4896ce28' for instanceId. Instance does not have a volume attached at root (/dev/sda1) this error pops up when I try to start my large windows server. I've remounted the drives to the large development server, and I still get this message. I'm not really sure what to do, I've read other posts and everyone is giving these almost like command line arguments and talking about other tools, and I really have no clue what any of that means, or where I even have an option to enter any commands without be logged into a specific instance.

• Mac OS X bypass proxy for certain domains

  - by Brian

  In college I'm behind a proxy. When I try to visit one of my local Apache virtual hosts behind the proxy, then my college DNS attempts to resolve the host, thus bypassing my local host file. In the advanced setting for proxies you seem to be able to enter values into "Bypass proxy settings for these Hosts & Domains". I added the last 2 to the end - "*.local, 169.254/16, *.dev, *.sb". But it doesn't work. Is there a solution?
