• IE8 no honoring display:none

  - by user357034

  I have the following markup on a page and unfortunately I do not have direct access to it. . This page is opened in an iframe. There is other code on the page but it is not relevant so I have not posted it. The only access to target the code in via css. I want to not display the close button so I added this to the css file img[alt='Close'] {display:none !important;} this is the markup <td align="center"><a href='javascript:window.close()'><img src='v/vspfiles/templates/100/images/buttons/btn_close.gif' alt='Close' border=0></a></td> It works as expected in all browsers that i have tested (firefox, Opera, Safari) but in IE8 it seems to ignore this css and shows the button. Not sure if it doesn't like the selector or perhaps I have a syntax error. Not sure where to go from here.

• SVN Attribution Plugin?

  - by Rosarch

  I'm using SVN with Google Code Project Hosting for a school project. As the codebase increases in size, I often find myself wondering questions like: "who originally checked in this line of code?" "who has been checking in the most code recently?" "Of the final product, how much of it was written by Person X?" "Which coder is best at adhering to the coding conventions?" Is there any plugin available to do this? (If not, I would be interested in developing one myself. Any ideas on where to get started on that?) We're using Visual Studio 2008 with the AnkhSVN plugin.

• OOWrite is to LaTeX as OODraw is to?

  - by grimborg

  I'm looking for a tool to nicely generate single-page PDFs. My needs are: Able to put a PDF/EPS/... as a background Absolute positioning Able to define tables, lists Able to rotate blocks Reasonably easy syntax (will be used to automatically generate many similar looking documents) Easily usable from Python Free or very cheap In essence I'm looking for the tool X that is to OODraw/CorelDraw/... as LaTeX is to OOWrite/MS Word. I've looked at webkit2pdf and a headless OODraw, but both seem a bit of an overkill. XML-FO has some limitations such as not being able to predict how many pages your document spans. Reportlab is pricey. Any ideas? Thanks!

• Visual C++ 2010 solution-wide macros with parameters

  - by OregonGhost

  I'm trying to compile some source code with Visual C++ 2010 Express. The code was written for GCC, and contains attributes like this: struct something { ... } __attribute__((packed)); Since this is not standard C++ syntax, Visual C++ doesn't recognize it. With this macro prior to the struct declaration, it works fine: #define __attribute__(p) But I don't want to alter the files. I created a new property sheet (GccCompat), and went to Preprocessor Definitions, and added the macro, like this: __attribute__(p) or like this: __attribute__(p)= But it doesn't work. It's simply not called. If I define just __attribute__ (without parameters) in the same location, the macro is correctly defined. Note that the command line that is generated looks fine (the macros with parameters are passed exactly the same as the ones without), but the compiler seems to ignore it. So, how can I globally define my macro with a parameter?

• Looking for a real-time IMAP notification of new Emails

  - by Emil

  I'm looking for a way to monitor a GMail inbox for new e-mails. However, I want to avoid checking every few minutes and I'm looking for some sort of real-time notification. I've noticed that Outlook (and other IMAP-supporting clients) instantly show when there is a new e-mail, but unfortunately all .NET IMAP libraries seem to lack this functionality. Does anyone know of an IMAP library that has this functionality? Or is there another way to be instantly notified of new message without doing some short-period polling?

• Convert Null Value to String - C#.NET

  - by peace

  foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { PropertyItem.SetValue(this, objDataTable.Rows[0][PropertyItem.Name.ToString()], null); } In one of the loops i get this exceptional error: Object of type 'System.DBNull' cannot be converted to type 'System.String'. The error occurs because one of the fields in the database has no value (null), so the string property could not handle it. How can i convert this null to string? I got this solution If you know a shorter or better one, feel free to post it. I'm trying to avoid checking on every loop is current value is null or not.

• View a SYS.XMLTYPE returned from an Oracle function, using PL/SQL

  - by caerphilly

  I have an Oracle function that dynamically creates an XML document, and returns it in a SYS.XMLTYPE value. I want to run a query from SQL Developer that calls that function and prints the document (either via a select, or dbms_output - I don't care). But all the examples/documentation seem to refer to querying XML columns in tables, and I can't seem to get the syntax right for my particular usage. I'd like something like this: declare x SYS.XMLTYPE; begin x := my_package.my_function(); select x.getclobval() from x; -- doesn't work! end; How can I print out the value of the XML type variable 'x' in the above code?

• "Compiling" content with short tags to var, without eval()

  - by Spot

  To start off, let me clear the air by saying we are aware of the dis/advantages to using short tag syntax in PHP. That is not what this question is about. Is there a way to "include" a file containing short tag code, into a variable, and have PHP actually parse the code? include/require obviously do not provide the data in a workable form, and output buffering does not parse the short tag code because it happens at runtime. Using eval() is simply not an option. Suggestions?

• OpenExeConfiguration Path Issue

  - by Harry

  I'm trying to load an web.config from a server. Its placed at: \server\folders\web.config when i try this: ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.config"); it searches for: web.config.config and fails. ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web"); it fails, because there is no folder \server\folders\web\ So i tried several things and it seems as its checking wether the file the path is pointing on exists, and afterwards it appliers a .config and gets the config file. Just for fun i created an web.loaders file, and a web.loaders.config file. with ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.local"); it loads the \server\folders\web.local.config perfectly, but throws Exceptions without the web.local file. So there a many ways to get this small thing loaded, but isn't there a more nice one than using a temp .web file or something? Any help i highly appreciated, yours Harry

• I DISTINCTly hate MySQL (help building a query)

  - by Alex Mcp

  This is staight forward I believe: I have a table with 30,000 rows. When I SELECT DISTINCT 'location' FROM myTable it returns 21,000 rows, about what I'd expect, but it only returns that one column. What I want is to move those to a new table, but the whole row for each match. My best guess is something like SELECT * from (SELECT DISTINCT 'location' FROM myTable) or something like that, but it says I have a vague syntax error. Is there a good way to grab the rest of each DISTINCT row and move it to a new table all in one go?

• E4X in ActionScript

  - by Brian Genisio

  Hey all, Looking at the E4X implementation in ActionScript, it occurs to me that they had to figure out how to do three things that I am not sure can be done within ActionScript regularly: Properties/Getters prefixed with @: var myAttribute = xmlPerson.@name; Nameless functions for filtering: xmlData.person.(/* predicate */) lambda syntax for predicates: xmlData.person.(@name == "Brian") So here is my question: Are these just one-off capabilities (much like Vector.<>) they put in just for E4X, therefore keeping out of reach for us? Or do we, as ActionScript developers, have access to these features? More specifically, I'd love to get access to the expression tree of that lambda predicate for my own code (not tied to the XML classes in any way). I figured out that this is called the "filter operator"... but I am not sure how to harness it. Not sure I can... since ActionScript does not allow for operator overloading :(

• Finding all points common to two circles

  - by Dustin I.

  In Python, how would one find all points common to two circles? For example, imagine a Venn diagram-like intersection of two (equally sized) circles, with center-points (x1,y1) and (x2,y2) and radii r1=r2. Additionally, we already know the two points of intersection of the circles are (xi1,yi1) and (xi2,yi2). How would one generate a list of all points (x,y) contained in both circles in an efficient manner? That is, it would be simple to draw a box containing the intersections and iterate through it, checking if a given point is within both circles, but is there a better way?

• What ASP.NET MVC project files should I not add to Subversion

  - by Dan

  this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

• C# - Error if Windows Media Player is not supported

  - by f4bzen

  i´m using the windows media player (Interop.WMPLib.dll & AxInterop.WMPLib.dll) in my c#-project to stream a mp3 from a server. The only problem is, if the windows media player is somehow not supported on a pc (not installed or something), my application just gives an error (no exception, just a "windows-error") and won´t start. So, is it possible to check, if the windows media player is supported? Just checking if the OS is supported will probably not help. Are there maybe some better ways to stream mp3s than with the WMP ? Thanks in advance.

• Excel VBA to check autofilter for data

  - by cav719

  I need help checking for autofiltered rows not including the header. I want it to give a message box "No records found." then exit sub or continue with copy paste if there are rows beyond the header row.

Here is my script: Private Sub Searchbycompanyfield_Click() If CompanyComboBox1.Value = "" Then MsgBox "Please enter a Company to begin search."

• How does dereferencing of a function pointer happen?

  - by eSKay

  Why and how does dereferencing a function pointer just "do nothing"? This is what I am talking about: #include<stdio.h> void hello() { printf("hello"); } int main(void) { (*****hello)(); } From a comment over here: function pointers dereference just fine, but the resulting function designator will be immediately converted back to a function pointer And from an answer here: Dereferencing (in way you think) a function's pointer means: accessing a CODE memory as it would be a DATA memory. Function pointer isn't suppose to be dereferenced in that way. Instead, it is called. I would use a name "dereference" side by side with "call". It's OK. Anyway: C is designed in such a way that both function name identifier as well as variable holding function's pointer mean the same: address to CODE memory. And it allows to jump to that memory by using call () syntax either on an identifier or variable. How exactly does dereferencing of a function pointer work?

• Where to start with C#

  - by RobertPitt

  Hello fellow programmers. Im a pretty experienced programmer in PHP and mainly web languages but today i have decided i want to start to learn a new language! Im only 21 and I feel as I will never make it in the programming industry without a great set of languages under my belt, So i decided to have a look at C#. The reason I have chosen C# is because some C programmers have told me that C# is the best language to learn for desktop applications. I think i need to get started with the Syntax / Structure of C#, What Development Environment to use, and other things that i might face along my new journey. I hope somebody can guide me Thanks.

• jQuery is it possible to concatenate two selector variables?

  - by Kris Hollenbeck

  Lets say I have two variables defining separate selectors, for example... var parent = $('.parent'); var child = $('.child'); And I want to create a something like the following... $(parent + child).click(); Which should be equivalent to doing this (if it was correct syntax)... $('.parent .child').click(); This may not be best practice, however I am curious if it is possible. Thanks for your help in advance.

• Dang Error #1009 !

  - by boz

  I'm building a simple flash site for a friend who has a spa. I keep getting this error: Error #1009: Cannot access a property or method of a null object reference. at spa7_fla::MainTimeline/frame1() through the process of commenting out code, i've narrowed down to my link section: vox_link.addEventListener(MouseEvent.CLICK,gotoVox); function gotoVox(evtObj:Event):void { var voxSite:URLRequest=new URLRequest("http://www.voxmundiproject.com"); navigateToURL(voxSite, "_blank"); } With this section commented out, i don't get the 1009 error. When the code is active, I get the error. My code syntax is correct so I'm stumped. Does someone have an idea what my be wrong? Thanks!

• Problem with debug watch in Visual Studio with yield return enumerator methods

  - by Stuart

  I have a method which returns an IEnumerable<> which it builds up using the yield return syntax: public IEnumerable<ValidationError> Validate(User user) { if (String.IsNullOrEmpty(user.Name)) { yield return new ValidationError("Name", ValidationErrorType.Required); } [...] yield break; } If I put a breakpoint in the method, I can step over each line, but if I try to use the Watch or Immediate windows to view the value of a variable I get this error: Cannot access a non-static member of outer type '[class name].Validate' via nested type '[class name]' Does anyone know why this is and how I can get around it?

• Rails 3: Validate combined values

  - by Cimm

  In Rails 2.x you can use validations to make sure you have a unique combined value like this: validates_uniqueness_of :husband, :scope => :wife In the corresponding migration it could look like this: add_index :family, [:husband, :wife], :unique => true This would make sure the husband/wife combination is unique in the database. Now, in Rails 3 the validation syntax changed and the scope attribute seems to be gone. It now looks like: validates :husband, :presence => true Any idea how I can achieve the combined validation in Rails 3? The Rails 2.x validations still work in Rails 3 so I can still use the first example but it looks so "old", are there better ways?

• Is block style really this important?

  - by Jack Roscoe

  I just watched a video of Douglas Crockford's presentation about his 2009 book JavaScript: The Good Parts. In the video, he explains that the following block is dangerous because it produces silent errors: return { ok: false }; And that it should actually be written like this (emphasising that although seemingly identical the behavioural difference is crucial): return { ok: false }; You can see his comments around 32 minutes into the video here: http://www.youtube.com/watch?v=hQVTIJBZook&feature=player_embedded#!&start=1920 I have not heard this before, and was wondering if this rule still applies or if this requirement in syntax has been overcome by JavaScript developments since this statement was made. I found this very interesting as I have NOT been writing my code this way, and wanted to check that this information was not out of date.
