  • ASP.net MVC 3 adding arbitrary text to the end of an ActionLink

    - by infensus
    Hi I have a question about Html.ActionLink. Imagine: @Html.ActionLink(item.title, "Singlet", new { id = item.blog_id }) produces http://[url]/[controller]/Singlet/[id] But what if I want to suffix some more arbitrary data at the end? For example: http://[url]/[controller]/Singlet/[id]/#comments To jump to the comments div. I know I can just make the string myself with something like: @( new HtmlString(String.Format("<a href=\"Blog/Singlet/{0}/#comments\">link to comments</a>", item.blog_id)) ) But I am hoping there is a cleaner way, perhaps with ActionLink? Thanks

  • What does Rails script/server -d do differently that would cause a cells template to not be found

    - by Brian Deterling
    I'm using cells. I used the generator to create a cell so the path to my template was automatically chosen to be app/cells/displayer/table.html.erb where displayer is the name of the cell and table is the name of the state. When I run script/server in the foreground, everything works perfectly. But when I run script/server -d, I get "Missing template displayer/table.erb in view path app/cells:app/cells/layouts". Even if I change table.html.erb to table.erb, I see the same message - the ActionView code is checking both but not finding either. Even if you're not familiar with cells, does anyone know what happens differently in daemon mode related to view paths? In this case, it appears that the plugin is not correctly registering the view path.

  • Speeding up inner joins between a large table and a small table

    - by Zaid
    This may be a silly question, but it may shed some light on how joins work internally. Let's say I have a large table L and a small table S (100K rows vs. 100 rows). Would there be any difference in terms of speed between the following two options?: OPTION 1: OPTION 2: --------- --------- SELECT * SELECT * FROM L INNER JOIN S FROM S INNER JOIN L ON L.id = S.id; ON L.id = S.id; Notice that the only difference is the order in which the tables are joined. I realize performance may vary between different SQL languages. If so, how would MySQL compare to Access?

  • Where to put conditionals in ANSI-syntax SQL queries

    - by RenderIn
    What's the difference between these two queries? I've been resistant to jumping on the ANSI-syntax bandwagon because I have not been able to unravel various syntactical ambiguities. Is 1) returning the product of the join and only then filtering out those joined records which have weight = 500? And is 2) filtering out those prior to the join? Is 2 bad syntax? Why might I use that? 1: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME WHERE BAR.WEIGHT < 500 2: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME AND BAR.WEIGHT < 500

  • scope of variables in JavaScript callback functions

    - by Ethan
    I expected the code below to alert "0" and "1", but it alert "2" twice. I don't the reason. Don't know if it is a problem of jQuery. Also, please help me to edit title and tags of this post if they are inaccurate. <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(function() { for (var i=0; i<2; i++) { $.get('http://www.google.com/', function() { alert(i); }); } }); </script> </head> <body> </body> </html>

  • Timestamp as int field, query performance

    - by Kirzilla
    Hello, I'm storing timestamp as int field. And on large table it takes too long to get rows inserted at date because I'm using mysql function FROM_UNIXTIME. SELECT * FROM table WHERE FROM_UNIXTIME(timestamp_field, '%Y-%m-%d') = '2010-04-04' Is there any ways to speed this query? Maybe I should use query for rows using timestamp_field >= x AND timestamp_field < y? Thank you I've just tried this query... SELECT * FROM table WHERE timestamp_field >= UNIX_TIMESTAMP('2010-04-14 00:00:00') AND timestamp_field <= UNIX_TIMESTAMP('2010-04-14 23:59:59') but there is no any performance bonuses. :(

  • Upgrading Visual Studio web service project says to "convert to web application."

    - by Buggieboy
    I have a Visual Studio 2003 web service project that I have to upgrade to Visual Studio 2008. After I have run the conversion wizard, I get this message: You have completed the first step in converting your Visual Studio .NET 2003 web project. To complete the conversion, please select your project in the Solution Explorer and choose the 'Convert to Web Application' context menu item. I got this message with another project, which was originally a "web site", rather than an ASP.NET "web application". It made sense to in that case (sort of). Why, however, would I not just want to have this project remain a web service project? Additionally, when I follow the instructions and select "Convert to Web Application" from the context menu, I don't get any feedback that anything has changed. Should it have? If so, what?

  • How to add a field from a 2nd form?

    - by PowerUser
    Hi all. I'm modifying an existing Lotus view to include a field from another form. I first appended a new column and set it to the desired field. However, after I refreshed, the new column was blank even though I know it has data. I then updated the View Selection formula from: SELECT Form = "A" & StatusIndex < "06" to: SELECT (Form = "A"| Form = "B") & StatusIndex < "06" Still no luck. The view is refreshing successfully, but the new field is still blank. What else is there to add this new column to this view? This is my first time experimenting with Lotus, so if I seem to be missing some major concept, I probably am.

  • Cost-effective .Net solutions for report generation in Excel and PDF

    - by jamesaharvey
    I'm looking for some cost-effective solutions and/or open source options for generating reports in Excel and PDF format. I realize some of the open source options may have less in terms of functionality and flexibility than the COTS versions with all the bells and whistles, but are there any options out there that fall somewhere in between? EDIT: Essentially what I'll have are just some basic HTML reports of data in tables with some calculations/summary data but nothing fancy like graphs, etc. I'll then need the ability to export these HTML reports to Excel and/or PDF.

  • How to force HtmlUnit to save page?

    - by booroondook
    Hello. I'm using HtmlUnit to click on a HtmlElement that triggers Javascript action: currentPage = ((HtmlElement) currentPage.getByXPath("//*[contains(@onclick, 'check();')]").get(0)).click(); The element is: <a href="#" onclick="check(); return false;"> The page returned is quite similar to the page, containing that element: same URL, mostly same HTML, but there are some minor differences in the HTML and HtmlUnit doesn't save the new page. I'm using HttpAnalyzer to sniff the traffic and I see that the Webclient correctly handles JS and send the right request. The response is also correct, but when I dump the contents of the currentPage to a file, I see that the actual page didn't change. How can I fix it?

  • sql and pooled connection error

    - by user319075
    Dear all, Kindly look at the following code as this sample code gives an error when i hosted it on Hostexcellence , but locally it runs perfect, and the error is as the following: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached SqlDataSource1.SelectCommand = "Select Top (3) * from News Order by NewsID Desc"; SqlDataSource1.DataSourceMode = SqlDataSourceMode.DataReader; SqlDataReader r_News = (SqlDataReader)SqlDataSource1.Select(DataSourceSelectArguments.Empty); DataGrid_News.DataSource = r_News; r_News.Close(); DataGrid_News.DataBind(); So What's wrong with that code ??

  • Selecting an element based on class and id in jquery - similar to an SQL query

    - by Ankur
    I want to select an element based on it's class and id, I have seen many similar questions on SO. Most of the users ask why would you ever want to do this - which is not very helpful, trust me, this is the simplest way of solving my UI problem, and it's a very unique and intereting UI related to making generic triple stores easily browsable. At the moment the jQUery looks like this: $(document).ready( function() { $(".predicates").hide(); $(".objects").hide(); $("#subject").click( function() { $("#predId, .predicates").toggle(); // this line } ); $("#predId").click( function() { $("#objId, .objects").toggle(); } ); }); The line I am really interested in is this $("#predId, .predicates").toggle(); how do I get the select to ensure that both #predId and .predicates are true, at the moment it seems that only one or the other has to be true. Is there something like an && operator?

  • SQL vs MySQL: Rules about aggregate operations and GROUP BY

    - by Phazyck
    In this book I'm currently reading while following a course on databases, the following example of an illegal query using an aggregate operator is given: Find the name and age of the oldest sailor. Consider the following attempt to answer this query: SELECT S.name, S.age FROM Sailors.S The intent is for this query to return not only the maximum age but also the name of the sailors having that age. However, this query is illegal in SQL--if the SELECT clause uses an aggregate operation, then it must use only aggregate operations unless the query contains a GROUP BY clause! Some time later while doing an exercise using MySQL, I faced a similar problem, and made a mistake similar to the one mentioned. However, MySQL didn't complain and just spit out some tables which later turned out not be what I needed. Is the query above really illegal in SQL, but legal in MySQL, and if so, why is that? In what situation would one need to make such a query?

  • how to run javascript from .NET code ?

    - by dotnetcoder
    I have a webrequest that returns a html response which has form inside with hidden fields with some javascript that submits the form automatically on pageload ( if this was run in a browser). If I save this file as *.html and run this file in browser , the java script code automatically posts the form and the output is excel file. I want to be able to generate this file(excel) from a c# code which is not running in broswer. I tried mocking thr form post but its complicated and has various scenarios based on the original webrequest querystring. any pointers.... i know its not possible to probably run JS code that posts the form - from within c# code but still thought of chekcing if someone has done that.

  • MySQL INSERT data does not get stored in proper db, only temporary?

    - by greye
    I'm having trouble with MySQL or Python and can't seem to isolate the problem. INSERTs only seem to last the run of the script and are not stored in the database. I have this script: import MySQLdb db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="example") dbcursor = db.cursor() dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'before: '+str(temp) dbcursor.execute('INSERT INTO tablename (data1, data2, data3) VALUES ("1", "a", "b")') dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'after: '+str(temp) The first time I run it I get the expected output: >>> before: () after: ((1L, 'a', 'b'),) The problem is that if I run it again, the before comes out empty when it should already have the entry in it and the after doesn't break (data 1 is primary key). >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) If I try running the insert command twice in the same script it will break ("Duplicate entry for PRIMARY KEY") Any idea what might be happening here?

  • Font-awesome, input type 'submit'

    - by denis.peplin
    It seems no class for input type 'submit' in font-awesome. Is it possible to use some class from font-awesome for button input? I've added icons to all buttons (which actually links with class 'btn' from twitter-bootstrap) in my applications, but can't add icons on 'input type submit'. Or, how to use this code: input#image-button{ background: #ccc url('icon.png') no-repeat top left; padding-left: 16px; height: 16px; } html: <input type="submit" id="image-button">Text</input> (which I took from HTML: How to make a submit button with text + image in it?) with font-awesome?

  • When does a query/subquery return a NULL and when no value at all?

    - by AspOnMyNet
    a) If a query/subquery doesn’t find any matching rows, then it either returns NULL or no value at all, thus not even a NULL value. Based on what criteria does a query/subquery return a NULL and when doesn’t it return any results, not even a NULL value? b) I assume a scalar subquery will always return NULL, when no matching rows are found? I assume most-outer scalar query also returns NULL if no rows are found? c) SELECT FirstName, LastName, YEAR(BirthDate) FROM Persons WHERE YEAR(BirthDate) IN (SELECT YearReleased FROM Albums); If subquery finds no results, is then a WHERE clause of an outer query translated into WHERE YEAR(BirthDate) IN (null); ? If instead WHERE clause is translated into WHERE YEAR(BirthDate) IN(); then shouldn’t that be an error condition, since how can YEAR(BirthDate) value be compared to nothing? thanx
