• Expanding DIV slides behind DIV beneath it...

  - by Paddy

  I'm not sure that I'm going to get an answer here, as I'd need to post a lot of CSS and html to get a working recreation, however... I have structure something like this: <fieldset> <legend>Test A</legend> <h3>Test A</h3> <p> Something here. </p> <div style="display:hidden;">I'm dynamically displayed</div> </fieldset> <fieldset> <legend>Test B</legend> <h3>Test B</h3> <p> Something B here. </p> </fieldset> I have code that toggles the display of my hidden div using jQuery and .show(). This works fine in IE8, firefox and Safari, but when I stick IE8 into compatibility mode, then the first fieldset (Test A) will expand, but the expansion happens behind the second fieldset, which doesn't move (i.e. it slides down behind it). I have quite a bit of CSS in use here, and I'm going to have to go back and unpick the whold lot, which isn't a fun idea. If anybody has any idea of one of the IE7 rendering issues that might be affecting this, then I'd very much appreciate it. (note that there is more to the content in these fieldsets than shown, including floated divs). Quick note - if I stick IE7 into quirks mode, it works (but wrecks the rest of my layout) - in standards mode, I get the above behaviour.

• Utility of List<T>.Sort() versus List<T>.OrderBy() for a member of a custom container class

  - by ccomet

  I've found myself running back through some old 3.5 framework legacy code, and found some points where there are a whole bunch of lists and dictionaries that must be updated in a synchronized fashion. I've determined that I can make this process infinitely easier to both utilize and understand by converging these into custom container classes of new custom classes. There are some points, however, where I came to concerns with organizing the contents of these new container classes by a specific inner property. For example, sorting by the ID number property of one class. As the container classes are primarily based around a generic List object, my first instinct was to write the inner classes with IComparable, and write the CompareTo method that compares the properties. This way, I can just call items.Sort() when I want to invoke the sorting. However, I've been thinking instead about using items = items.OrderBy(Func) instead. This way it is more flexible if I need to sort by any other property. Readability is better as well, since the property used for sorting will be listed in-line with the sort call rather than having to look up the IComparable code. The overall implementation feels cleaner as a result. I don't care for premature or micro optimization, but I like consistency. I find it best to stick with one kind of implementation for as many cases as it is appropriate, and use different implementations where it is necessary. Is it worth it to convert my code to use the LINQ OrderBy instead of using List.Sort? Is it a better practice to stick with the IComparable implementation for these custom containers? Are there any significant mechanical advantages offered by either path that I should be weighing the decision on? Or is their end-functionality equivalent to the point that it just becomes coder's preference?

• SharpDevelop WIX project: MSBuild Configurations

  - by chezy525

  Using SharpDevelop, I wrote a windows service with a WIX setup project to install/auto-start it. For testing purposes, I've done a number of things I don't want to do in the release version (i.e. add an uninstall shortcut to the desktop). So, my question really boils down to this; how do you handle build configurations within a WiX project? I think I've solved most of my problems after I found this question Passing build parameters to .wxs file to dynamicaly build wix installers. And thus far I've done the following: Added a property that checks the Configuration variable <Product> ... <Property Id="DEBUG">$(var.Configuration) == 'Debug'</Property> ... Separated all of the debug files into unique components and setup as a separate feature with a condition checking the DEBUG property. <Product> ... <Feature> ... <Feature Id="DebugFiles" Level="1"> <ComponentRef Id="UninstallShortcutComponent" /> <Condition Level="0">DEBUG</Condition> </Feature> ... Then, finally, pointing to the correct file based on the configuration, using the Configuration variable <Directory> ... <Component> <File Source="..\mainProject\bin\$(var.Configuration)\main.exe" /> </Component> ... So, now my question is simplified to how to handle files that may not exist under certain build configurations (like .pdb files). Using all of the above (including pointing the file source to the ...\bin\Release\*.pdb, which I know isn't expected to exist) I get a LGHT0103 compiler error, it can't find the file.

• DOMAIN REDIRECT PROBLEM WITH JQUERY / JAVASCRIPT

  - by GiovanniDema

  Hi guys, first time here. I got a strange problem. I have a fullscreen image scaler javascript (as GOTOCHINA website) that works very well on my website. Then, I purchased a domain redirect pointing on my website and when redirecting suddenly internet explorer 7 and internet explorer 8 give me this error Messagge: is not a valid argument. Line: 34 Char: 17 URI: http://*****/scaler.js The script is var db=document.body; var imag=document.getElementById('wallpaper'); var dbsize={}; var imgsrc=imag.src; var keyStop=function(e){ var e=window.event||e||{}; var tag=e.target.tagName.toLowerCase(); if(tag!='textarea'&&!(tag=='input'&&(e.target.type=='text'||e.target.type=='password'))){ if(e.keyCode==32||e.keyCode==39||e.keyCode==40){ if(e.preventDefault)e.preventDefault(); else e.returnValue=false; } } } if(this.addEventListener)window.addEventListener('keydown',keyStop,false); else window.attachEvent('onkeydown',keyStop); setInterval(function(){ window.scrollTo(0,0); if(imag.complete){ if(db.clientWidth!=dbsize.w||db.clientHeight!=dbsize.h||imag.src!=imgsrc){ imgsrc=imag.src; var dbsizew=db.clientWidth; var dbsizeh=db.clientHeight; var newwidth=Math.round(dbsizeh*(imag.offsetWidth/imag.offsetHeight)); var nextvar=dbsizewnewwidth?dbsizew:newwidth; imag.style.width=nextvar+'px'; } } },300); In other words when i open the official website everything's working correctly. When i open redirect domain pointing on official website... the previous error appears. The line is exactly this - imag.style.width=nextvar+'px'; Thanks in advance Giovanni

• rails not recognizing project

  - by tipu

  I can create a new project using rails and I can use stuff like rails migration ... and i (correctly) get a error because the sqlite gem is missing. but when i try using rails migration ... with a project i checked out from github, it doesn't recognize that it is a rails project i get: Usage: rails new APP_PATH [options] Options: -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /usr/bin/ruby1.8 [--skip-gemfile] # Don't create a Gemfile and it goes on. any ideas? edit: it's probably an important detail that earlier my rails wasn't working at all. i had to cp /usr/bin/ruby to /usr/bin/local/ruby

• Is there a way for -webkit-animtion-timing-function to apply to the entire animation instead of each keyframe?

  - by Ken Sykora

  I'm a bit new to animation, so forgive me if I'm missing a huge concept here. I need to animate an arrow that is pointing to a point on a curve, let's just say it's a cubic curve for the sake of this post. The arrow moves along the curve's line, always pointing a few pixels below it. So what I did, is I setup keyframes along the curve's line using CSS3: @-webkit-keyframes ftch { 0% { opacity: 0; left: -10px; bottom: 12px; } 25% { opacity: 0.25; left: 56.5px; bottom: -7px; } 50% { opacity: 0.5; left: 143px; bottom: -20px; } 75% { opacity: 0.75; left: 209.5px; bottom: -24.5px; } 100% { opacity: 1; left: 266px; bottom: -26px; } } However, when I run this animation using -webkit-animation-timing-function: ease-in, it applies that easing to each individual keyframe, which is definitely not what I want. I want the easing to apply to the entire animation. Is there a different way that I should be doing this? Is there some property to apply the easing to the entire sequence rather than each keyframe?

• What the heck is the "Structure and Interpretation of Computer Programs" cover drawing about?

  - by Paul Reiners

  What the heck is the Structure and Interpretation of Computer Programs cover drawing about? I mean I know what "eval", "apply", and '?' all mean, but I'm having a hard time deciphering the rest of the picture. Who the heck is the maiden? Does she work for the wizard? Why the heck is she pointing at the table? Is she pointing at that little bowl-type thing? Or the books? Or the table in general? Is she trying to tell the wizard that he should apply some sort of Lisp wizardry to the table or the items on it? Or is she just telling him something prosaic, such as his food is getting cold? What the heck is the one leg on that table that looks like...a leg...with a foot at the end (as legs tend to have)? How does the table balance on one leg? (Or is that another leg in the shadows?) [Note: I'm waiting for a lengthy build to finish in case you were wondering.]

• Switching between 2 UINavigationControllers

  - by Smikey

  Hi all, I seem to have a problem switching between 2 UINavigationControllers, i.e. one which controls the main (selection) menu of my application, and the second which controls the main session (i.e. the user can't go back to the selection menu once they're started a new session). The first works just fine, but I get into trouble when trying to load the second. I have a class called GameViewController which contains the second UINavigationController instance. I set this up as usual, linking it as an IBOutlet to the delegate and setting up the NavController in the GameViewController.xib file with its 'Class' property pointing at GameScreenViewController (my main game screen), and its NIB Name property pointing to the GameScreenViewController nib file. I then create a new instance of GameViewController and load it. In IB, the navigation controller looks fine, with its View 'loaded from "GameScreenViewController"', however when the NavigationController is loaded in the game, it actually loads the GameViewController's UIWindow instance (just a blank window). I'm not sure how to make it load the Navigation Controller's view rather than its own window? Also, another quick question. When I load the second navigation controller from the first, which makes more sense to use: [self.view addSubview:gameViewController.view]; or [self presentModalViewController:gameViewController animated:YES]; Thanks for any help, much appreciated :D Michael

• Assigning address to array from heap

  - by Schaltfehler

  I want to save the state of my structs as a binary file and load them again. My structs look like this: typedef struct { uint8_t pointerLength; uint8_t *pointer; uint8_t NumBla; uinT16 Bla[MAX_NUM_Bla]; ... } BAR_STRUCT, *BAR; typedef struct { int numBar; BAR bars[MAX_NUM_BAR]; } FOO_STRUCT, *FOO; Saving is no problem, but restoring the state. Iam at the point where the bytestring from the file is on the heap and a pointer is pointing to the first adress of this string. And I do as follows: const void* dataPointer //points to adress in heap unsigned char* bytePointer = (unsigned char*)dataPointer; FOO foo = (FOO_STRUCT*)bytePointer; bytePointer += sizeof(FOO_STRUCT); for (int i=0; i < MAX_NUM_BAR; i++) { foo->bars[i] = (BAR_STRUCT*)bytePointer; } The last assignment doesn't work and I get an EXC_BAD_ACCESS. Because bars is an array of pointers i need to correct the adresses of each element is pointing to. Because they are not valid anymore. So I try to assign the adress of the object I saved in the bytesteam to foo-bars[i]; But I can not change foo-bars[i] at all. Accessing works but but assigning a new adress doesn't. I wonder why.

• Installing backtrack - No Screens Found when running “startx”

  - by Chris

  I'm installing backtrack to use for a project for my wireless networking class. I have an Acer Aspire One netbook and I'm installing from bootable USB stick. When I type "startx", it goes through the motions of giving me a bunch of text, followed by: "Fatal server error: no screens found" What gives? This is a fairly new laptop I guess, but why is this happening? How can I solve this?

• Finding all domains registered in a nameserver

  - by Florian

  Up until now, I was pretty confident that it was pretty much impossible to list all the domains handled by a nameserver. But apparently, there exists a couple of websites on the Internet that are able to list all the domains registered in a namerserver. For example: http://www.gwebtools.com/ns-spy/udns1.ultradns.net Or all domains pointing to a specific IP : http://www.robtex.com/ip/190.7.200.92.html (These DNS/IP were picked at random) Do you know how it's done ?

• Getting macro keys from a razer blackwidow to work on linux

  - by Journeyman Geek

  I picked up a razer blackwidow ultimate that has additional keys meant for macros that are set using a tool that's installed on windows. I'm assuming that these arn't some fancypants joojoo keys and should emit scancodes like any other keys. Firstly is there a standard way to check these scancodes in linux? Secondly how do i set these keys to do things in command line and x based linux setups? My current linux install is xubuntu 10.10, but i'll be switching to kubuntu once i have a few things fixed up. Ideally the answer should be generic and system-wide Things i have tried so far: showkeys from the built in kbd package (in a seperate vt) - macro keys not detected xev - macro keys not detected lsusb and evdev output this ahk script's output suggests the M keys are not outputting standard scancodes Things i need to try snoopy pro + reverse engineering (oh dear) Wireshark - preliminary futzing around seems to indicate no scancodes emitted when what i seem to think is the keyboard is monitored and keys pressed. Might indicate additional keys are a seperate device or need to be initialised somehow. Need to cross reference that with lsusb output from linux, in 3 scenarios - standalone, passed through to a windows VM without the drivers installed, and the same with. LSUSB only detects one device on a standalone linux install It might be useful to check if the mice use the same razer synapse driver , since that means some variation of razercfg might work (not detected. only seems to work for mice) Things i have Have worked out: In a windows system with the driver, the keyboard is seen as a keyboard and a pointing device. And said pointing device uses, in addition to your bog standard mouse drivers.. a driver for something called a razer synapse. Mouse driver seen in linux under evdev and lsusb as well Single Device under OS X apparently, though i have yet to try lsusb equivilent on that Keyboard goes into pulsing backlight mode in OS X upon initialisation with the driver. This should probably indicate that there's some initialisation sequence sent to the keyboard on activation. They are, in fact, fancypants joojoo keys. Extending this question a little I have access to a windows system so if i need to use any tools on that to help answer the question, its fine. I can also try it on systems with and without the config utility. The expected end result is still to make those keys usable on linux however. I also realise this is a very specific family of hardware. I would be willing to test anything that makes sense on a linux system if i have detailed instructions - this should open up the question to people who have linux skills, but no access to this keyboard The minimum end result i require I need these keys detected, and usable in any fashion on any of the current graphical mainstream ubuntu varients

• MediaWiki on MS Sql Server

  - by kdbolt70

  Hello all, I've been doing some digging on running mediawiki on sql server instead of mySQL, but haven't come across any concrete information. All of our servers are running SQL Server so I'd like to stick with that. I've tried Screwturn wiki, which is an ASP.NET wiki implementation using SQL Server, but I'm not terribly happy with the editing interface, and would really like to get MediaWiki up and running. Does anyone know if this is possible? Thanks!

• Why can't I wrap text around grouped images in Word?

  - by Ivo Flipse

  When I paste two images into Microsoft Word and I set Wrap Text to Square and then group them so they stick nicely together, I can no longer Wrap Text around this newly grouped image. Any explanation to why text wrapping is disabled for grouped images? Note: if I don't change the Wrap Text option, I can't group them. This is for Word 2010 on Windows 7, but I've had this problem with every version of Word.

• How to create a Windows 7 installation usb media from linux ? (to install Windows 7) - Help need to know better method

  - by Abel Coto

  I have been reading some web pages and posts here and in other forums about how to create a Windows 7 installation Usb media (to install windows 7 using a usb) from linux. I asked in technet about this , and they give me general ideas about how to do it I personally am not very familiar with linux, but basicaly all that you need to do... in whatever way you do it is the following: Format a usb flash drive, either fat32 or ntfs create a partition that is large enough to host the windows installation (give or take 3GB for 64bit, aroudn 2.5gb for 32bit) and mark that partition as active/bootable. Since this can be done with windows, but just as well with a tool like gparted, you should be able to do the same in debian. Once you have created that partition, mount the iso that you download, and copy all files starting from the root, into the root of the usb flash drive. That's all there's to it. There is a method that i found in various places,that is almost the same that the man of technet has said. But,there is a step,that in that method is done,that i don't know if it is really necessary,or not. Not allways dd works.Basically, the missing step was to write a proper boot sector to the usb stick, which can be done from linux with ms-sys. This works with the Win7 retail version. Here is the complete rundown again: Install ms-sys Check what device your usb media is asigned - here we will assume it is /dev/sdb. Delete all partitions, create a new one taking up all the space, set type to NTFS, and set it bootable: *# cfdisk /dev/sdb* Create NTFS filesystem: *# mkfs.ntfs -f /dev/sdb1* Mount iso and usb media: *# mount -o loop win7.iso /mnt/iso # mount /dev/sdb1 /mnt/usb* Copy over all files: *# cp -r /mnt/iso/* /mnt/usb/* Write Windows 7 MBR on usb stick: *# ms-sys -7 /dev/sdb* ...and you're done. Shouldn't the usb work without doing the last step "# ms-sys -7 /dev/sdb" or to make the usb bootable , is a must , not only to mark the partition as bootable ? Would be better use rsync instead of cp -r ? All this steps should be done as root, i suppose , or if not , chmod to 664 and chown the directories where are mounted the usb and the iso, no ? But i suppose that the easier thing is to copy the data as root , and that this will not affect to the data. Has anyone tried this method or some similar like copying the iso with dd ?

• Virtual LTSP server with KVM

Does someone have any experience with this setup? I've had a similar setup with VMware Server 2 and Ubuntu 8.04. How good/bad is kvm compared to VMware for a LTSP appliance? Shall I stick with VMware or can I switch to KVM?

However, I was under the impression bootcamp provided the most optimal drivers for windows 7 to run on my MBP's hardware. Should I stick with what bootcamp gives for my video driver, or update to the one windows 7 suggests?

• Should my web server add trailing slashes to URLs or remove them?

  - by jnm2

  I've read in several places that you should decide whether you want trailing slashes or no trailing slashes in your site URLs and stick to your choice consistently. This makes sense, but which should I pick? Is there a convention I ought to follow, performance to be gained, or is it totally up to my taste? (I notice that the StackExchange sites link without trailing slashes, but SE doesn't redirect if you add a slash.)
