  • Combining position: relative with float in CSS

    - by user74847
    I have always thought of position: relative and float: left as different tools that should be used separately, with some features that overlap. position should be used for positioning things relative to the viewport and float used for floating things within a container. Today I saw someone combining float: left and position: relative also using top: 10px, when they could have used margin top on the floated element and not added the position relative at all. It is obviously not wrong to do it in this way because it works, but what is the best practice? Should position relative be used on an element as well as float?

  • Custom vs. browser-native scrollbars

    - by vemv
    Including customizable, JavaScript-based scrollbars (and scrolling functionality in general, i.e. bind the control to the mouse scroll wheel) in your webapp can be a great temptation. However all solutions I could find were developed by individuals (which can equal lack of formal or future support). In addition I fail to remember any mainstream site using them. In my particular case, no-JavaScript or IE6/odd-browser environments are not intended to be supported. Should custom scrollbars be avoided nowadays? If not, what's the best option one can choose?

  • Difference between "/" at end of URL and without "/" [closed]

    - by user702325
    Possible Duplicate: Does it make a difference if your url ends in a trailing slash or not? Why treat these as different URLs? I am doing a 301 redirect in my WP application using .htaccess and have mapped some of the URLs which have either been removed from the new domain or the URL structure has been changed. While doing I got a doubt I have following URL structure in my .htaccess file RewriteCond %{HTTP_HOST} ^old.com$ [OR] RewriteCond %{HTTP_HOST} ^www.old.com$ RewriteRule ^tag/waiting$ http://www.new.com/tag/relationships [R=301,L] while checking this i found that at some places URL is like http://www.new.com/tag/relationships while at others its like http://www.new.com/tag/relationships/, while both refer to the same location but not sure if this will make any difference to SEO and search engines.

  • Entity Framework looking for wrong column

    - by m.edmondson
    I'm brand new to the Entity Framework and trying to learn all it can offer. I'm currently working my way through the MVC Music Store tutorial which includes the following code: public ActionResult Browse(string genre) { // Retrieve Genre and its Associated Albums from database var genreModel = storeDB.Genres.Include("Albums") .Single(g => g.Name == genre); return View(genreModel); } as I'm working in VB I converted it like so: Function Browse(ByVal genre As String) As ActionResult 'Retrieve Genre and its Associated Albums from database Dim genreModel = storeDB.Genres.Include("Albums"). _ Single(Function(g) g.Name = genre) Return(View(genreModel)) End Function The problem is I'm getting the following exception: Invalid column name 'GenreGenreId'. Which I know is true, but I can't for the life of my work out where it's getting 'GenreGenreId' from. Probably a basic question but I'll appreciate any help in the right direction.

  • Do I need Response.End() in ASP.Net 2.0

    - by Hamish Grubijan
    Hi, I am just starting with ASP.Net. I copied a ex-co-worker's code (from .Net 1.1 era) and it has a Response.End(); in case of an error. There is also a: catch (Exception ex) { Response.Write(ex.Message); Response.End(); } at the end of Page_Load(object sender, System.EventArgs e) which always appends "Thread was aborted." or something like that at the end. I suspect that this worked differently before, or the error conditions were not tested very well. Anyhow, I was able to stop using Response.End(); in case when I do not like the GET parameters, and use return; instead. It seemed to do the right think in a simple case. Is this Ok in general? There are some problems with the code I copied, but I do not want to do a rewrite; I just want to get it running first and find wrinkles later. The Response.End(); caused a mental block for me, however, so I want to figure it out. I want to keep the catch all clause just in case, at least for now. I could also end the method with: catch (System.Threading.ThreadAbortException) { Response.End(); } catch (Exception ex) { Response.Write(ex.Message); Response.End(); } but that just seems extremely stupid, once you think about all of the exceptions being generated. Please give me a few words of wisdom. Feel free to ask if something is not clear. Thanks! P.S. Ex-coworker was not fired and is a good coder - one more reason to reuse his example.

  • Public folder not visible from front end Exchange 2003 Server

    - by Kyle Brandt
    I have a public folder that does not receive emails when the emails are sent via the Front-End Exchange Servers. When I go into the System Manager on the Front-End I don't see this particular public folder listed under the Public Folders. However, I do see it listed from the Front-End server. I see the emails that are not making it to the public folder listed in the local delivery queue on the front end server and they are in a retry state. Does anyone know how I might troubleshoot this?

  • GVim Stop at end of line with arrows

    - by viking
    When using the arrow keys in Vim on Linux, they act the same way as h and l , stopping when the end of a line is reached. GVim on Windows doesn't do this, instead allowing the arrow keys continue past the end (or beginning) of a line and on to the next line. Is there any way to change the arrow key behaviour and cause them to stop at the end of a line like the character navigation keys? NOTE: I am not looking for a way to get to the beginning or end of a line, I realize that 0 and $ do this.

  • How to take search query and append modifers to the end of it

    - by Kimber
    This is a greasemonkey question. What I'm trying to do is modify an old google discussions script. What were wanting to do is be able to take the google search query and add modifiers to the end of it. Like this: search query: "superuser" modifiers: inurl:greasemonkey+question end result: "superuser" inurl:greasemonkey+question The old script creates a new div within the "hdtb_more_mn" element which is where you get the new discussions tab. However, since the "tbm=dsc" option to do a discussion search has died, this script no longer works. Hence the need to add modifiers to your searches. I tried to edit the script, but it appends the modifiers to the end of the url which includes "&client=firefox-a&hs=8uS&rls=org.mozilla:en-US:official". This means you're also searching for the above as well as your query, which doesn't work. I would like to be able to append the modifiers @ the end of the search querty, rather than the whole URL. I'm just not sure how to code it to where it adds the below "&tbm=" stuff within "discussionDiv.innerHTML" to the end of the query. The google search id seems to be, "gbqfq" for the search box, but I'm not sure how to add this id. Here is the old script // ==UserScript== // @name Add Back Google Discussions // @version 1.4 // @description Adds back the Discussion filters to Google Search // @include *://*.google.tld/search* // ==/UserScript== var url = location.href; if (url.indexOf('tbm=dsc') < 0) addFilterType('dsc', 'Discussions'); function addFilterType(val, name) { var searchType = document.getElementById('hdtb_more_mn'); var discussionDiv = document.createElement('DIV'); discussionDiv.className = 'hdtb_mitem'; discussionDiv.innerHTML = '<a class="q qs" href="'+ (url.replace(/&tbm=[^&]*/g,'') + '&tbm=' + val) +'">'+name+'</a>'; searchType.innerHTML += discussionDiv.outerHTML; } Thanks for any help, or suggestions on who to ask. Google Chrome has an extension for discussion searches, but FF doesn't seem to have one as of yet, which is why I'm trying to modify the above.

  • Find/Replace Paragraph End (^13) in Microsoft Word 2007 Merges Paragraphs

    - by Mike Blyth
    I need to replace a target at the beginning of lines with something else. Without wildcards, I can say to replace "^pTarget" with "^pReplacement". With wildcards enabled, I use replace "^13Target" with "^13Replacement". The replacement is successful except that the paragraph is now merged with the previous one in a strange way: The end-paragraph mark is still in place and the paragraph begins on a new line, but Triple clicking to select paragraph selects both the changed paragraph and the one above In a macro, starting in the paragraph above and extending the selection to the end of paragraph causes both paragraphs to be selected. Inter-paragraph spacing disappears between the changed paragraph and the one above. In essence, the paragraph boundary has been removed although the end-paragraph mark is still shown. To duplicate this problem, make a new document Line 1 Line 2 Line 3 (separate paragraphs). Find and replace (with wildcards on) "^13" with "^13". If your result is the same as mine, you will see the problems listed above. I can work around this in the usual way of replacing ^p with something else first, e.g. "^p" = "$", then "$target" = "$replacement", but I'm curious about what's going on. (This is using Word 2007 on Windows 7) I don't know Word XML, but the XML output seems to correspond with the above. Replacing ^13 with ^13 moves the paragraphs together in almost the same way as replacing end-paragraph with end-line (^p = ^l). Here is the relevant XML of the original "Line 1, Line 2, Line 3" in separate paragraphs: <w:p w:rsidR="00BB3032" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> </w:p> <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 2</w:t></w:r> </w:p> <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 3</w:t></w:r> </w:p> Now after replacing ^13 with ^13: <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> <w:r><w:t>Line 2</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> <w:r><w:t>Line 3</w:t></w:r> <w:r w:rsidR="00C57863"><w:cr/></w:r> </w:p> Now original after replacement of ^p with ^l (convert end-paragraph to end-line) <w:p w:rsidR="00027252" w:rsidRDefault="00027252"> <w:r><w:t>Line 1</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> <w:r><w:t>Line 2</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> <w:r><w:t>Line 3</w:t></w:r> <w:r w:rsidR="00AC7B51"><w:br/></w:r> </w:p>

  • Front End Developer positions for Recent Graduates

    - by Rajat
    Is it just me or there is a serious dearth of Front End Web Developer positions for recent grads. I have been working as one for the last 6 months now after my graduation and I understand that most of the front-end skills are not taught at academia and the profession requires a lot of discipline and patience to learn them on your own. I see a plethora of opportunities for recent grads for back-end positions but very few for front end positions. Does the industry have an understanding that Front-End positions require more expertise than back-end positions? Just my thoughts but not many people seem to keen to hire recent grads for front-end positions.

  • BDE, Delphi, ODBC, SQL Native Client & Dead lock

    - by EspenS
    Hi. We have some Delphi code that uses the BDE to Access SQL Server 2008 through the SQL Server Native Client ODBC driver (2005 version). Our issue is that we're experiencing some deadlock issues in a loop doing inserts to multiple tables. The whole loop is done within a [TDatabase].StartTransaction. Looking at the SQL Server Profiler we clearly see that at one point during the loop the SPID (Session ID?) change, and then we naturally end up with a deadlock. (Both SPID doing inserts to the same table) It seems like the BDE at some point does a second connection to the DB... (Although I would love to skip the BDE, it's currently not possible. ) Anyone with experiences to share?

  • What do you do if you reach a design dead-end in evolutionary methods like Agile or XP?

    - by Dipan Mehta
    As I was reading Martin Fowler's famous blog post Is Design Dead?, one of the striking impressions I got is that given the fact that in Agile Methodology and Extreme Programming, the design as well as programming is evolutionary, there are always points where things need to get refactored. It may be possible that when a programmer's level is good, and they understand design implications and don't make critical mistakes, the code continues to evolve. However, in a normal context, what is the ground reality in this context? In a normal day given some significant development goes into product, and when critical change occurs in requirement isn't it a constraint that how much ever we wish, fundamental design aspects cannot be modified? (without throwing away major part of the code). Is it not quite likely that one reaches dead-end on any further possible improvement on design and requirements? I am not advocating any non-Agile practice here, but I want to know from people who practice agile or iterative or evolutionary development methods, as for their real experiences. Have you ever reached such dead-ends? How have you managed to avoid it or escaped it? Or are there measures to ensure that design remains clean and flexible as it evolves?

  • Splitting MS Access Database - Front End Part Location

    - by kristof
    One of the best practices as specified by Microsoft for Access Development is splitting Access application into 2 parts; Front End that hold all the object except tables and the Back End that holds the tables. The msdn page links there to the article Splitting Microsoft Access Databases to Improve Performance and Simplify Maintainability that describes the process in details. It is recommended that in multi user environment the Back End is stored on the server/shared folder while the Front End is distributed to each user. That implies that each time there are any changes made to the front end they need to be deployed to every user machine. My question is: Assuming that the users themselves do not have rights to modify the Front End part of the application what would be the drawbacks/dangers of leaving this on the server as well next to the Back End copy? I can see the performance issues here, but are there any dangers here like possible corruptions etc? Thank you EDIT Just to clarify, the scenario specified in question assumes one Front End stored on the server and shared by users. I understand that the recommendation is to have FE deployed to each user machine, but my question is more about what are the dangers if that is not done. E.g. when you are given an existing solution that uses the approach of both FE and BE on the server. Assuming the the performance is acceptable and the customer is reluctant to change the approach would you still push the change? And why exactly? For example the danger of possible data corruption would definitely be the strong enough argument, but is that the case? It is a part of follow up of my previous question From SQL Server to MS Access 2007

  • What key works like End using a Mac with Synergy

    - by Toby Allen
    I have recently got a Mac mini to do IPhone Dev on (like many others) and I am using the excellent Synergy to share one keyboard and mouse with 2 machines and 2 monitors. Everything is lovely and it works a treat. I got used to using the mac, and the alt key works like command button on the mac however one thing I cant figure out is the End key. I use this a lot on windows when wanting to jump to the end of a line of text, however if I press it over synergy on my mac it jumps to the end of the page. Anyone know the key combination I need to get what I want?

  • Delphi - Message loop for Form created in DirectShow filter goes dead

    - by Robert Oschler
    I have a DirectShow filter created with Delphi Pro 6 and the DSPACK direct show library. I'm running under windows XP. I've tried creating the form dynamically when the container class for the DirectFilter has its constructor called, passing NIL into the constructor as the AOwner parameter (TMyForm.Create(nil) and then calling the Form's Show() method. The form does show but then appears to stop receiving windows messages because it never repaints and does not respond to input. As a test I then tried creating my own WndProc() and overriding the Form's WndProc(). My WndProc() did get called once but never again. I'm guessing it's because I'm a DLL and the context that I am running in is not "friendly" to the window message handler for the form; perhaps something to do with the thread that calls it or whatever. If someone could give me a tip on how to solve this or what the proper way to create a persistent window is from the context of a DirectShow filter I'd appreciate it. Note, as I said the window needs to be persistent so I can't create it as a Filter property page. Thanks, Robert

  • Is literate programming dead?
