• Any way to do slanted/diagonal mouseovers via css/javascript?

  - by cksubs

  Hi, I have a box built via html borders. I want to connect the bottom left corner to the top right corner with a diagonal line. Either with html/css or by using a background image, doesn't matter. I'll figure that part out later. ------ - /- - / - - / - -/---- Here's the tricky part: I want a different thing to happen depending on which side of the line the mouse is hovering over. I'll do something like make some text visible or change the background color. Is that possible in web programing? I've thought of doing a "Riemann sum" type calculation with a bunch of invisible divs. Any easier way? Thanks!

• x86 assembler question

  - by b-gen-jack-o-neill

  Hi, I have 2 simple, but maybe tricky questions. Let´s say I have assembler instruction: MOV EAX,[ebx+6*7] - what I am curious is, does this instruction really actually translates into opcode as it stands,so computation of code in brackets is encoded into opcode, or is this just pseudo intruction for compiler, not CPU, so that compiler before computes the value in brackets using add mul and so, store outcome in some reg and than uses MOV EAX,reg with computed value? Just to be clear, I know the output will be the same. I am interested in execution. Second is about LEA instruction. I know what it does, but I am more interested wheather its real instruction, so compiles does not further change it, just make it into opcode as it stands, or just pseudo code for compiler to, again, first compute adress and than store it.

• Is there a way in Sphinx/Pygments to emphasize one or more lines of code in literal includes?

  - by Casey

  In some sphinx docs I am writing, I am including code samples from an ancillary file like so: .. literalinclude:: mymodule.py :pyobject: MyClass :linenos: This particular doc is a tutorial, where the classes are build up step by step. What I would like to do is include the entire class or a single method, and emphasize only the lines of interest to that section. That way the context is preserved but the interesting parts are obvious at a glance. Right now I have resorted to just referring to line numbers in the text, which is ok, but far from ideal. Looking at the docs and code for sphinx and pygments I don't find an obvious way to do this. I'm not opposed to patching them or doing something tricky in conf.py, but I wondered if anyone had solved this.

• ATL OR C# for windows shell/namespace extenssion?

  - by _Avishay_

  Hi, i have a question, after allot of hours in googling and reading articles, i understood that namespace extenssion in windows is quite tricky (In C++ at least), now i've also seen its possible to do so in C# , but microsft does'nt officaly confirms using .net for namespace extensions... though i have seen very nice commercial Namespace Extenssion framework , but none is free.... so to my question :) , i want to develop my own Namespace Extenssion ,i have C++/C# knwoledge and basic COM/ATL , but if it can be done i prefer c#, so does c# inteop can fully do the work without too many tricks ? or one shall go diving in the ATL to create the neccessary COM objects... and another question , can i program to Windows O/S with C# anything that can be done in C++/ATL/MFC ? thanks!

• GWT vertical layout

  - by skrat

  I need a vertical layout, which would fill browser's viewport top to bottom, with on overflow (scrollbars). I need to layout widgets on the top, and on the bottom, and have one widget in the center which would stretch to fill the remaining space. There seems to be DockLayoutPanel for this purpose, the problem with it is that it forces me to specify widget sizes, and I don't know the sizes of the top/bottom widgets before the browser does it's layouting job, which is tricky (buggy) to track. I cannot find the right moment when to measure my widgets, and I don't want to do this kind of layouting code anyway.

• Using Server side method from Javascript without AJAX

  - by Aswin Ramakrishnan

  I have a tricky problem. I am in a situation where I need to use a method defined in a .cs file from a javascript function. The problem is we are using .NET 1.1 and AJAX cannot be used for the application. Also, I will need to pass a string from the javascript to the server side method. The page where I am implementing the javascript is a .as Any ideas? I have tried doing a post back and creating a RaisePostBack event handler method (both in the .aspx page and the .ascx user control) but no luck. It will be greatly appreciated if someone could help me out with the problem.

• loading HTML fragments with jQuery

  - by sam

  Hi everybody, I'm very new to jQuery, Ajax and things like these. I've found solutions on how to inject HTML fragments into my site: $(document).ready(function(){ $('a').click(openContent); //binding all anchors to this function }); function openContent(){ var path = $(this).attr('href'); $('#content').load(path); return false; //to prevent browser from loading the single HTML fragment } That works really fine! The problem is, these function won't be executed when clicking on anchors located in the new HTML fragment which were injected right before. So the fragment won't get injected into div, the browser will only load the fragment for itself. Hope there are solutions which aren't that tricky... thanks sam

• Verify mail server connection programmatically

  - by Sergii

  I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials. Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server. Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid. I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant. Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated. Thanks in advance.

• Connect two UIScrollView's together

  - by johnw188

  Here's a tricky iPhone problem I've been working on. I have three UIScrollViews on a page, one that only scrolls horizontally, one that only scrolls vertically, and one that scrolls both horizontally and vertically. I want to lock the views together, so that the horizontal location of the horizontal only scrollview matches the horizontal location of the main scrollview, and the vertical scrollview likewise, so that dragging the main scrollview around controls the horizontal and vertical scrollviews. Problem is, I'm completely stumped. I've looked around inside the apple documentation, but there doesn't seem to be any way to do this officially. One thought that I had was to somehow "clone" any touch on any of the scrollviews to a point on the other two, but I have no idea how to do this. If anyone has any thoughts on this, I'd very much appreciate it.

• How Do I Convert text to a WAV file With Inaudible Waveform?

  - by Scott

  I am trying to create an audio watermarking system. I figure the best solution is to create an audio file (WAV) based on a unique string of text and then combine this with the original wav. The part that makes this tricky (for me anyway) is: How do I convert the text string to a wav? How do I ensure that the resulting WAV form is inaudible (or at least barely noticeable to the listener). I would prefer this be done server side (via PHP, etc) but if the processing load isn't too much then would be ok with something in Flash or Javascript. I'd be willing to pay someone to create me a workable solution (complete source code that functions as described). Thanks, Scott!

• Help need to with MySQL query to join data spanning multiple tables and use data as column names

  - by gurun8

  I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

• Conditional Join - join 1 tables 2 ways

  - by Jon H

  I have a set of (not very well normalised or relational) tables named PLAN, GROUP, PRODUCT CLIENT Most have linkage i.e. PLAN - CLIENT on clno GROUP to PRODUCT on PRODCD However, the linkage between PLAN and GROUP is tricky. A plan has 2 field of interest GRPNO and PRODCD. What I want to do is if GRPNO != 0 then join GROUP on GRPNO. However if GRPNO = 0 then I want to join GROUP on PRODCD. The frustrating thing is that the fileds I want to return in my queries are the same across the board I just need to be able to vary the join, or join the same table twice. The best I can come up with is 2 queries and merge them using datasets, or possibly using a union. Is there a nifty way to do this in one select? I should point out I am access Foxpro over ODBC to do this. Thank you!

• How do I properly implement Unicode passwords?

  - by Sorin Sbarnea

  Adding support for Unicode passwords it an important feature that should not be ignored by the developpers. Still adding support for Unicode in the passwords it's a tricky job because the same text can be encoded in different ways in Unicode and this is not something you may want to prevent people from logging in due to this. Let's say that you'll store the passwords os UTF-8. Now the question is how you should normalize the Unicode data? You had to be sure that you'll be able to compare it. You need to be sure that when the next Unicode standard will be released it will not invalidate your password verification. Note: still there are some places where Unicode passwords are probably never be used, but this question is not about why or when to use Unicode passwords, is about how to implement them the proper way.

• How to move an element in a sorted list and keep the CouchDb write "atomic"

  - by karlthorwald

  I have elements of a list in couchdb documents. Let's say these are 3 elements in 3 documents: { "id" : "783587346", "type" : "aList", "content" : "joey", "sort" : 100.0 } { "id" : "358734ff6", "type" : "aList", "content" : "jill", "sort" : 110.0 } { "id" : "abf587346", "type" : "aList", "content" : "jack", "sort" : 120.0 } A view retrieves all "aList" documents and displays them sorted by "sort". Now I want to move the elements, when I want to move "jack" to the middle, I could do this atomic in one write and change it's sort key to 105.0. The view now returns the documents in the new sort order. After a lot of sorting I could end up with sort keys like 50.99999 and 50.99998 after some years and in extreme situations run out of digits? What can you recommend, is there a better way to do this? I'd rather keep the elements in seperate documents. Different users might edit different elements in parallel (which also can get tricky). Maybe there is a much better way?

• SQL partial max

  - by Rob

  Struggling with the following SQL problem Assume a three dimensional table with entries (h,t,q) 1,A,20 1,A,10 1,B,5 2,A,10 2,B,3 2,B,8 3,C,50 4,A,10 etc. I would like to extract 1,30 2,11 3,50 etc. group by first element and then return the maximum q value of same type, i.e. for header number 2 there are 10 As and 11 Bs, so return 11 The "max" element (A in case 1, B in case 2 and C in case 3) is irrelevant, I just need to get out the header and that maximum value. This shouldnt be too tricky, but cant get it to work. Using MS Access, but can use SQL within.

• How do I get the value of a DynamicControl?

  - by Telos

  I'm using ASP.NET Dynamic Data functionality to do something a little weird. Namely, create a dynamic list of fields as children of the main object. So basically I have Ticket.Fields. The main page lists all the fields for Ticket, and the Fields property has a DynamicControl that generates a list of controls to collect more data. The tricky part is that this list ALSO uses Dynamic Data to generate the controls, so each field can be any of the defined FieldTemplates... meaning I don't necessarily know what the actual data control will be when I try to get the value. So, how do I get the value of a DynamicControl? Do I need to create a new subclass of FieldTemplate that provides a means to get at the value?

• Getting a Target to run BEFORE anything else runs when building from Visual Studio

  - by damageboy

  Hi, I'm trying to get a one-time costly target to run only when building a certain top-level project (that has many dependencies). I have no problem on getting this working from plain msbuild / command line build. I do this with setting and InitialTargets on the project, or alternatively with < BeforeBuild /. The tricky part is with Visual Studio. When I build the same project from VS. VS runs the dependencies before even invoking my .csproj, so my target (which affects how the other projects are built) doesn't get to run until they have already been built. Is there someway to force VS to run a target before invoking the dependencies? I'm currently working around this, by running the same costly target from my most low-level project (the one that get's always built...) by using: Condition=" $(BuildingInsideVisualStudio) " Any ideas on how to get this done "properly"? Again, I'm looking for a solution that will work FROM VS.

• Wordpress auto excerpts from post content?

  - by Scott B

  I'm trying to create an auto generated post excerpt from the current page's post content using a function in my theme's header file. The post excerpt will be used as the page's meta description. Can someone give me an idea of how you might go about this once you've got the post content into a string variable? The somewhat tricky part is that, in order to predict a viable stopping point for the post excerpt, I'd like to specify that the cutoff point be the end of the first paragraph of text. And for that reason, it does not make sense to load the entire post content into the string I'm using. Can I grab the first paragraph without having to load the entire post content string? And I'm not certain how to test for that in php. Would regex be the only way?

• SQL Server 2008 automated database drop, create and fill

  - by lox

  For the database in my project I have a drop/create script for the database, a script for creating tables and SPs and an Access 2003 .mdb file with some exported values. To set up the database from scratch I can use my SQL management studio to first run one script, then the other and lastly manually run the sort of tedious import task. But I would like to do this as automated as possible. Hopefully something like putting the three files in a folder along with a fourth script to execute. Looking something like: run script "dropcreate.sql" run script "createtables.sql" import "values.mdb" How is this done? I hope to avoid using SSIS and the like. The tricky this is of course the import of data, where I can't seem to find a simple way. It is also important that the files a left as they are and not embedded into anything.

• Has anyone ever encountered a Monad Transformer in the wild?

  - by martingw

  In my area of business - back office IT for a financial institution - it is very common for a software component to carry a global configuration around, to log it's progress, to have some kind of error handling / computation short circuit... Things that can be modelled nicely by Reader-, Writer-, Maybe-monads and the like in Haskell and composed together with monad transformers. But there seem to some drawbacks: The concept behind monad transformers is quite tricky and hard to understand, monad transformers lead to very complex type signatures, and they inflict some performance penalty. So I'm wondering: Are monad transformers best practice when dealing with those common tasks mentioned above?

• IIS7 or .Net 301 Redirects from 1 domain to another

  - by RandomBen

  I have 2 domains. For the question, I will call them www.old.com and www.new.com. Both urls are pointing to the same IIS7 Site instance. I need to it up so that when someone goes to www.old.com they get a 301 redirect to www.new.com. The tricky part is I am using URL rewrites for pages within the site. So www.old.com/About.aspx redirects to www.new.com/About. To get that to work with IIS7 URL rewrite rules, it also means that www.new.com/About.aspx redirects to www.new.com/About. That is fine and is not a big deal. My issue is how do I redirect the main domain without losing the URL Rewrites from the sub pages? I don't care if I use a module within IIS7 or if I need to do it in .NET code.

• What is the correct way to unit test areas around exceptions

  - by Codek

  Hi, Looking at our code coverage of our unit tests we're quite high. But the last few % is tricky because a lot of them are catching things like database exceptions - which in normal circumstances just dont happen. For example the code prevents fields being too long etc, so the only possible database exceptions are if the DB is broken/down, or if the schema is changed under our feet. So is the only way to Mock the objects such that the exception can be thrown? That seems a little bit pointless. Perhaps it's better to just accept not getting 100% code coverage? Thanks, Dan

• PHP: prevent invocation of method X from from context != Y

  - by sunwukung

  This is a tricky one. I am "emulating" ZF Bootstrapping (surface appearance). Don't ask me why, call it academic interest. So I have a Bootstrap Abstract with a method "run" that iterates over itself to locate any methods prefixed with "init". The application looks for a user defined class which extends this class, in which the user can define any number of methods in this way. However, I want to prevent the user from being able to execute the "run" command of it's parent class, while still exposing the same command for the client code. Anyone got any thoughts/advice/guidance? regards SWK
