• Hiding text under an image for SEO purposes

  - by JCHASE11

  I am going to use a large image on my page with a bunch of text on it. The reason I am including body text on an image is because the text will be rotated, and there currently isn't any GREAT solution for rotating text seamlessly across all browsers. On this image, there is a lot of text, and I want it to be indexed by search engines. (but its a picture so it's content won't be indexed, obviously) If I was to include a div with all the text html and set the css to display:none, would Google still index the content that is hidden under the picture? Are their any other solid solutions here?

• What is the max LINQ Expression Trees can do?

  - by yeeen

  What is the maximun that LINQ expression Tree can do? Can it define a class? How about a method, with all the declared name, modifiers, parametertype and return type? Must the program always define the tree himself? Is it possible to generate the tree from a given C# file? Where can I get resources to learn about writing basic to advanced Expression Tree and Expression Tree Visitor? (articles and videos will be great) Thanks for those who are able to help...

• Scala Eclipse IDE suddenly ignoring breakpoints

  - by malsmith

  I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code. Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck. I would greatly appreciate ideas for fixes. Rather frustrating as the initial experience with 2.8 was really great.

• Build turns partially transparent image pixels black

  - by Sean O'Hollaren

  I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them. The images are in .png format to allow transparency, and smoothing the edges in GIMP leaves some semi-transparent pixels. I've set the Image List Toolbar (imglToolbar)'s properties to recognize "Transparent" as the designated color to show up as transparent. I'm working in Visual Studio 2005. The strange thing is that everything looks great when I'm viewing the Visual C# form preview window. The icons look exactly as they should. However, once I actually build the project, the buttons treat every semi-transparent pixel near the edge of the image as if it's black. It seems like it can't handle one that's both transparent and has color. Image of it via the Visual C# form editor: Image of what it looks like when built: Any ideas as to why this is happening?

• Jquery toggle using 2 elements

  - by user801773

  this is my script, I'm using a toggle so I can animate a sliding menu. $("div.show-menu").click().toggle( function() { // first alternation $("#slideover").animate({ right: "512px" }, 300); $(".menu-button").html('close menu'); }, function() { // second alternation $("#slideover").animate({ right: "0" }, 300); $(".menu-button").html('open menu'); }); Though I really need the toggle to work using 2 elements on the page. For example see below... <div class="show-menu one">open menu</div> // this is element one <div class="show-menu two">open menu</div> // this is element two I need it so, if element one get's click first, you can close the menu using element two on the first click. What is happening now is that you have to click element two twice in order for it to close the menu - vice versa I guess this is the toggle coming into play, any help would be great thanks. Cheers Josh

• Multiple levels of 'collection.defaultdict' in Python

  - by Morlock

  Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

• Looking for a wiki-style, standalone, version-control-"safe" documenation package

  - by basszero

  This may sound like it's not a programming related question, but stick with me here... My team and I have found that documenting our project (a development platform w/ API) with a wiki is both useful to us and useful to the users. Due to some organizational issues, we're forced to do multi-site development without network connectivity. We've switched to a DVCS (Mercurial) and had great success with this. The wiki documentation proves to be a problem as the central site is setup with MediaWiki. The offsite people have no way to access or edit the wiki. Is there any sort of wiki-style package which doesn't not require a server/database and will be useable in a DVCS environment? Update: Should be open-source and cross-platform

• Cascading Dropdown Listboxes with Selenium

  - by Jon

  I am having great difficultly testing cascading dropdown boxes with Selenium. I would like to know what the standard approach is for this. I'm a bit unclear as to which commands to use i.e. ClickAndWait, WaitForTextPresent etc. It seems a little bit of a hack to try and get this to work. Has anyone got selenium to correctly test this out? An example scenario would be to have 3 listboxes which have Car Make, Model and Colour. Each one is populated in turn by the other. Selenium needs to somehow wait for the next listbox to populate before preceeding with the test.

• How do you check individual SqlCommands ran during a SqlTransactions to see if they will run?

  - by Sam F

  I've been reading up on SqlTransactions and have found a great load of examples like: http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=451 The problem is, when I do a BeginTransaction() (Execute all the commands) and then Commit() at the end all the commands I execute get run and the ones with syntax errors or other errors just get skipped. This is where I would also like to run a roll back, not skip over them. I found a few articles on the subject but they were not very helpful and purely in SQL. Is there any way to find out if one of the ExecuteNonQuery()'s failed before the commit and not just skipped? Thanks.

• One configuration per domain name on the same application. How to easily access config values from m

  - by Aymeric

  Hi, I run a Ruby on Rails website that have multiple domain names. I have a "Website" table in the database that stores the configuration values related to each domain name: Website - domain - name - tagline - admin_email - etc... At the moment, I load the website object at the start of each request (before_filter) in my ApplicationController: @website = Website.find_by_domain(request.host) The problem is when I need to access the @website object from my models methods. I would like to avoid to have to pass @website everywhere. The best solution would be to have something similar to APP_CONFIG but per domain name. def sample_model_property - - "#{@website.name} is a great website!" end How would you do it?

• Ruby/python Script to convert html text to plain text in csv file

  - by Miau

  Hi all: So i have a large(ish) file in a csv format, that contains a column that has html and i need to transform that to plain text (ie readable by people ,ie with no script tags) I dont have much experience with ruby, but it seems like the perfect language to do this The File should still be in a cv format after the parsing ( ie, other columns should nto be disturbed) Helpz? Fair enough, I thought there might be a library that does that as long as the html was valid. The file looks something liek this "xxxx-15454ss", "xome name", "<div class=""myClass""><strong>The Vintage Junior </strong>offers the same specs as the Vintage Series but only in 3/4 Size ideal for Kids. the 57 Model is great value for a good quality guitar. For more info go to <a href=""www.somehting.com"">something</a> </div> " I m trying to include the common html tags we would be using Thanks

• sharepoint spweb and spsite disposal

  - by user327045

  I've been using the following code in a .NET 1.1 SharePoint 2003 environment and it works great: try { site = SPControl.GetContextSite(Context); web = site.OpenWeb(); ... } catch (Exception export) { output.Write("Caught Exception: <br/><br/>"); output.Write(export.Message + "<br><br>"); output.Write(export.StackTrace); } finally { if (web != null) web.Dispose(); if (site != null) site.Dispose(); } However, I'm currently porting the code to a .NET 2.0 SharePoint 2007 environment and I get the following error message: "Trying to use an SPWeb object that has been closed or disposed and is no longer valid." If I comment out the Dispose() code, it works fine. But won't this cause memory leaks? What's the best way to fix the problem?

• Suggested C++ books?

  - by Josh Bradley

  Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

• How do I get a UIView which displays text to behave like a UILabel when bounds change?

  - by Hilton Campbell

  I have a UIView in which I need to draw text in drawRect: - (void)drawRect:(CGRect)rect { ... [@"some text" drawAtPoint:somePoint withFont:someFont]; ... } Because the text requires special formatting, I cannot just use a UILabel. It looks fine until I rotate the device. Then the size of my custom UIView changes (in the parent view's layoutSubviews method), and the text becomes stretched in one direction and squished in the other. When I replace my view with a UILabel, the text always looks great, even when the bounds of the view changes. How can I get my view to exhibit the same behavior as UILabel? Some things I have looked into, but have yet to have success with: Set the view's layer's needsDisplayOnBoundsChange to YES. Set the view's contentStretch to CGRectZero. Call setNeedsDisplay in my view's layoutSubviews. Maybe I'm not doing one of these things right. Has anyone else run into this?

• Database Schema Validation - deployable/compilable

  - by boomhauer

  Looking for a tool that will allow building database schema validation that can be compiled into a standalong tool or as a module to be used in another application. The scenario is - a client/server application that is sold to customers, and maintained through service releases. The service releases include database scripts to updated the database with any schema changes etc. However, since this is a database and the customer could either run upgrade scripts incorrectly, or tinker around and mess up something in the DB I would like to have this tool available with each release so we can verify the struture, and possibly some data, is valid. Also to have it available for remote debugging when a customer has a service ticket. Schema compare tools I've researched work great for comparing local databases, but I haven't seen something that can generate something that is deployable with our application. Thanks!

• How can I avoid setting some columns if others haven't changed, when working with Linq To SQL?

  - by Patrick Szalapski

  In LINQ to SQL, I want to avoid setting some columns if others haven't changed? Say I have dim row = (From c in dataContext.Customers Where c.Id = 1234 Select c).Single() row.Name = "Example" ' line 3 dataContext.SubmitChanges() ' line 4 Great, so LINQ to SQL fetches a row, sets the name to "Example" in memory, and generates an update SQL query only when necessary--that is, no SQL will be generated if the customer's name was already "Example". So suppose on line 3, I want to detect if row has changed, and if so, set row.UpdateDate = DateTime.Now. If row has not changed, I don't want to set row.UpdateDate so that no SQL is generated. Is there any good way to do this?

• TFS Automated Builds to Code Packages

  - by Adam Jenkin

  I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

• Write Local File using Adobe Air Iframe

  - by user290687

  This is driving me mad. I am creating an AIR application and everything is working great. However I would really like to have a form inside an Iframe that when the user clicks submit saves the file to local application storage directory. Right now I am able to do this and save the file with no problems when I just access the HTML page not inside an Iframe. However if I wrap the page in an iframe and hit submit the file does not save. Any code examples would be very much appreciated. When I am using the iframe my code looks as follows<iframe src="jobs/newjob.html" height="800px" width="800px" sandboxRoot="app:/" documentRoot="app:/sandbox"ondominitialize="setupBridge ()">

• Adding tables to sql server result in Domain\user.name.tablename

  - by Ryan Howe

  Our app uses migratordotnet to modify the backing SQL Server 2005 database. This works great 99% of the time but we are running into an issue. We have a client that is using and Active Directory group for sql server login and when new tables are added it creates them as Domain\login.table_name. What permissions are needed to be given to the AD group to add the tables as dbo.table_name? This does not happen in with all of our clients with similar configurations so I must be missing something.

• Getting value of specific item in combobox in Visual Basic 2013

  - by JaceG

  I'm having great difficulty trying to find how to simply get the text of one specific item in a ComboBox. I have cmbSelectedHinge as a dropdownlist style. All I need is to know what the text is in position 0. I would have thought simply: MsgBox(cmbSelectHinge.Items.IndexOf(0)) but no. It returns "-1" even though there is a line of text in it. It seems this question has never before been asked on the internet, and there's no useful information on MSDN. Any help, please

• Recommendation for tool/framework that follows the naked objects pattern?

  - by Marcus Munzert

  I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

• Are there any good reasons why I should not use Python?

  - by coppro

  I've heard from reliable sources that Python is a great language that every programmer can learn, but I've heard so much good about it that I'm clearly not getting the whole picture. I'm considering spending more time to learn it, and I've heard more than I need about its virtues (to the point where I've started recommending it having never really used it), so I want to know its drawbacks, flaws, issues, and every single minor point of irritation you've ever had (preferably with explanations readable to one who doesn't program Python, such as with an example in another language). Convince me not to try it out.

• understanding memory mapping in directx

  - by numerical25

  So my question is ... " When your using the mapping feature to write into a memory buffer, are you really just saving the whole procedure into a queue so directX executes it when finished with other tasks???" I ask this question because this is my perception of mapping when writing to a buffer. I just want to make sure my perception is correct. I understand that the monitor moves extremely slow in compared to the processor, and I am sure the processor can execute 10 times the amount the screen can refresh. So is this one of the reason you should map when writing to a buffer. so each procedure can be done in a orderly fashion. If someone could elaborate, that would be great. thanks

• bash find xargs grep only single occurence

  - by keftebub

  hi. maybe it's a bit strange - and maybe there are other tools to do this but, well.. i am using the following classic bash command to find all files which contain some string: find . -type f | xargs grep "something" i have a great number of files, on multiple depths. first occurence of "something" is enough for me, but find continues searching, and takes a long time to complete the rest of the files. what i would like to do is something like a "feedback" from grep back to find so that find could stop searching for more files. is such a thing possible? thank you
