• How to parse text fragments located after tag by simplehtmldom?

  - by moogeek

  Hello! I'm using simplehtmldom to parse html and i'm stuck in parsing plaintext that is located outside of any tag (but between two different tags): <div class="text_small"> <b>?dress:</b> 7 Hange Road<br> <b>Phone:</b> 415641587484<br> <b>Contact:</b> Alex<br> <b>Meeting Time:</b> 12:00-13:00<br> </div> Is it possible to get this values of Adress, Phone, Contact, Meeting Time? I wonder if there is a opportunity to pass CSS Selectors into nextSibling/nextSibling functions...

• Interchanging presentModalViewController and pushViewController

  - by Neffster

  I am using a sample ViewController that is displayed in the sample program as a presentModalViewController. However, I want to use pushViewController on the UIViewController instead. The problem is that when I switch to pushViewController, the ViewController no displays properly. Functions in the ViewController are called, but I don't see anything. I change back to presentModalViewController and everything works. The question is what do I need to do to make pushViewController work? FCVC *fcVC; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"fcVC" owner:self options:nil]; fcVC = [array objectAtIndex:0]; A. [self presentModalViewController:fcVC animated:YES]; // "WORKS" or B. [self.navigationController pushViewController:fcVC animated:YES]; // "Doesn't work

• Base class for windows service

  - by user187020

  My new project has a design in which there are number windows services for performing different tasks. I have been given a task to create base class from which all of the windows service will inherit. This base class will perform common functions like creating instances of other windows services by iterating through the config file (may be like Activator.CreateInstance), do event logging on onStart, onStop etc. and may contain some more functionality. Before I start developing stuff, wondering if there is any pattern already in place or someone has good understanding of how to implement this kind of functionality. Any help appreciated.

• Reference methods defined in one JScript file from another JScript

  - by Thomas Svensen

  I am writing some server-side scripts using jscript and WSH. The scripts are getting quite long, and some common functions and variables would fit better in a general library script which I included in my various script instances. But, I cannot find a way reference one JScript file from another. For a moment, I though reading the file contents and passing it to "eval()" could work. But, as it says on MSDN: "Note that new variables or types defined in the eval statement are not visible to the enclosing program." (http://msdn.microsoft.com/en-us/library/b51a45x6.aspx) Is there any way to include/refence a JScript from another one?

• JSP load external php not using iFrames

  - by Rudiger

  I have a bit of an issue with a site I maintain. I have been asked to add a report to a page that sits in a jsp page. The reporting information comes from a MySQL database. The problem is to connect the jsp to the database would require added functions to code that I do not have the original source of. I thought about redoing all the db connection again but thats a lot of time for something that will probably be rewritten in 3 weeks. Then I thought of just using PHP to display the report in the jsp as I have other pages connecting to the database using php (long story as to why were are using 2 languages). But the only way I know of is by using iFrames which is a bit of a no no. Using the object tag I've seen also has errors in IE. What would be the best way to do this?

Is there other preference ? the better way then the way i got now ?

• CurvyCorners in Wordpress Theme only rounds some corners in IE - what am I doing wrong?

  - by user346602

  Hi, I'm implementing the CurvyCorners script on a blog I'm developing. The script works in IE on some parts of the blog, but not others. I've used the following code to add it to the functions.php file (as suggested by someone smarter than me): function load_curvy_corners() { wp_enqueue_script('curvycorners', get_bloginfo('stylesheet_directory') .'/scripts /curvycorners.src.js','','',true); } add_action('init', 'load_curvy_corners'); Here is the site I'm working on: http://www.bellissimafashions.com/blog/ The container and logo area appear rounded in IE, but the navigation area is still square and seems to take awhile to load now. I don't know if this has something to do with the fact the theme I'm using (Pure II by beathemes) has placed the left side in the footer.php?

• Scalar-Valued Function in NHibernate

  - by Byron Sommardahl

  I have the following scalar function in MS SQL 2005: CREATE FUNCTION [dbo].[Distance] ( @lat1 float, @long1 float,@lat2 float, @long2 float ) RETURNS float AS BEGIN RETURN (3958*3.1415926*sqrt((@lat2-@lat1)*(@lat2-@lat1) + cos(@lat2/57.29578)*cos(@lat1/57.29578)*(@long2-@long1)*(@long2-@long1))/180); END I need to be able to call this function from my NHibernate queries. I read over this article, but I got bogged down in some details that I didn't understand right away. If you've used scalar functions with NHibernate, could you possibly give me an example of how your HBM file would look for a function like this?

• NSURLConnection still calls delegate AFTER cancel method has been called

  - by Shizam

  Hi All, Having a problem with NSURLConnection, if I create a NSURLConnection and call [connection connectionWithRequest] let it load a little then call [connection cancel] most of the time that works fine. However occasionally even after I call [connection cancel] the connection's delegate still gets called (which crashes the app). Googling around it looks like the problem here is a race condition in the runloop, I cancel the connection and release the delegate but before the runloop cycles it calls the delegate functions - crash. Is there a way for me to, after I call [connection cancel] confirm the connection has actually canceled? Even a crappy while() loop will do :(

  - by gkedmi

• A better JavaScript version of addslashes and stripslashes?

  - by karlthorwald

  I am using these 2 functions: http://javascript.about.com/library/bladdslash.htm But JSLint complains 'Bad Escapement' on this line: str=str.replace(/\\0/g,'\0'); [Edit] I converted to 2 lines, and now the first line is the one that fails JLint: var rep = '\0'; str=str.replace(/\\0/g,rep); So it is the '\0' can you help? I could try something but I want to understand what is going on. [/Edit] Can you make a better version and explain? I would like a version that passes JSLint and still works.

• Why does calling glMatrixMode(GL_PROJECTION) give me EXC_BAD_ACCESS in an iPhone app?

  - by MrDatabase

  I have an iphone app where I call these three functions in appDidFinishLaunching: glMatrixMode(GL_PROJECTION); glOrthof(0, rect.size.width, 0, rect.size.height, -1, 1); glMatrixMode(GL_MODELVIEW); When stepping through with the debugger I get EXC BAD ACCESS when I execute the first line. Any ideas why this is happening? Btw I have another application where I do the same thing and it works fine. So I've tried to duplicate everything in that app (#imports, adding OpenGLES framework, etc) but now I'm just stuck.

• Virtual Inheritance Confusion

  - by alan

  I'm reading about inheritance and I have a major issue that I haven't been able to solve for hours: Given a class Bar is a class with virtual functions, class Bar { virtual void Cook(); } What is the different between: class Foo : public Bar { virtual void Cook(); } and class Foo : public virtual Bar { virtual void Cook(); } ? Hours of Googling and reading came up with lots of information about its uses, but none actually tell me what the difference between the two are, and just confuse me more. Thanks!

• How to specify argument attributes in CFscript? (CF9)

  - by Henry

  In CF9 doc: Defining components and functions in CFScript, it says: /** *Comment text, treated as a hint. *Set metadata, including, optionally, attributes, in the last entries *in the comment block, as follows: *@metadataName metadataValue ... */ access returnType function functionName(arg1Type arg1Name="defaultValue1" arg1Attribute="attributeValue...,arg2Type arg2Name="defaultValue2" arg2Attribute="attributeValue...,...) functionAttributeName="attributeValue" ... { body contents } How do you specify arg1Attribute? I tried this: public void function setFirstname(string firstname="" displayName="first name"){} but it does NOT work. Also, how do you translate this to script-style? <cffunction name="setPerson"> <cfargument name="person" type="com.Person"/> </cffunction> I tried: function setPerson(com.Person person){} and it does NOT work either. "You cannot use a variable reference with "." operators in this context" it says.

• Optimizing Oracle query

  - by Omnipresent

  SELECT MAX(verification_id) FROM VERIFICATION_TABLE WHERE head = 687422 AND mbr = 23102 AND RTRIM(LTRIM(lname)) = '.iq bzw' AND TO_CHAR(dob,'MM/DD/YYYY')= '08/10/2004' AND system_code = 'M'; This query is taking 153 seconds to run. there are millions of rows in VERIFICATION_TABLE. I think query is taking long because of the functions in where clause. However, I need to do ltrim rtrim on the columns and also date has to be matched in MM/DD/YYYY format. How can I optimize this query?

• Eye Detection Problem In Opencv

  - by iva123

  Hi, I'm trying to convert this c code(http://nashruddin.com/OpenCV_Eye_Detection) to the python code, but in c style, he used cvROI thing, since ROI functions are not supported by python-opencv, I tried cvGetSubRect so Here is the eye detection part of the code : eye_region = cvGetSubRect(image,cvRect(face.x,int(face.y + (face.height/4)),face.width,int(face.height/2))) eyes = cvHaarDetectObjects(eye_region,eyeCascade,memo,1.15,3,0,cvSize(25,15)) for e in eyes: cvRectangle(image, cvPoint( int(e.x), int(e.y)), cvPoint(int(e.x + e.width), int(e.y + e.height)), CV_RGB(0, 255, 0), 1, 8, 0) return image; When I run this code, It draws rectangles irrelevant places. I thought, eye_region coordinates are wrong, and tried some coordinates, but it didn't work. Any idea ? Note :Face detection method works very well, and it's code is same with the eye detection method.

• ungetc in Python

  - by Dragos Toader

  Some file read (readlines()) functions in Python copy the file contents to memory (as a list) I need to process a file that's too large to be copied in memory and as such need to use a file pointer (to access the file one byte at a time) -- as in C getc(). The additional requirement I have is that I'd like to rewind the file pointer to previous bytes like in C ungetc(). Is there a way to do this in Python? Also, in Python, I can read one line at a time with readline() Is there a way to read the previous line going backward?

• .delegate equivalent of an existing .hover method in jQuery 1.4.2

  - by kim3er

  I have an event handler bound to the hover event using the .hover method, which is below: $(".nav li").hover(function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); It is important to note, that I require both functions within the handler to ensure synchronisation. Is it possible to rewrite the function using .delegate, as the following does not work? $(".nav").delegate("li", "hover", function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); Rich

• Selective PHP autoload

  - by Extrakun

  I am writing a add-on module which is integrated with an existing PHP application; Because I am using a MVC pattern, and which may requires lot of inclusion of classes (which might not be used at all depending on the action of the user), I decide to use autoloading of classes. However, I have to ensure that the autoload function does not interferes with the normal operations of the existing applications. Does autoload only kicks in if a class name is not defined? Say I have to write another module which uses its own autoload functions (say, I have an autoload for a module, since they each reside in their own folder), how do I differentiate which module is it for? For #2, I thought of 2 options. Either prefix the class name with the module name (Such as 'MyNewModule_View_Default' and 'AnotherModule_View_Default'), or use file_exists to check the include file exists. Other suggestions are welcomed too!

• Why is OnDragEnter not called?

  - by Harvey

  I have added the COleDropTarget variable to my view class, Registered it in the OnCreate(), which is being called at startup. I added the OnDragEnter and OnDrop virtual functions (not the others yet, as OnDragLeave). But they are not called when I drag (or drop) a piece of text over them. I just happened to think about the fact that I had already implemented the dropfiles function to the same window. Is this preventing the text drag? What else do I need? TIA, Harvey

• Proving that a function f(n) belongs to a Big-Theta(g(n))

  - by PLS

  Its a exercise that ask to indicate the class Big-Theta(g(n)) the functions belongs to and to prove the assertion. In this case f(n) = (n^2+1)^10 By definition f(n) E Big-Theta(g(n)) <= c1*g(n) < f(n) < c2*g(n), where c1 and c2 are two constants. I know that for this specific f(n) the Big-Theta is g(n^20) but I don't know who to prove it properly. I guess I need to manipulate this inequality but I don't know how

• Use absolute path for easier modify include path in future?

  - by i need help

  config.php put at the root level, this file will be included in any pages. Then at config.php <?php define( 'ROOT_DIR', dirname(__FILE__) ); ?> So at all other pages from different sub/a.php , sub/sub/b.php directories, when I want to include a specific file in specific location, I just need to include( ROOT_DIR.'/include/functions.php' ); In windows server, the ROOT_DIR bring the value to C:/inetpub/vhosts/domain.com Is this a good/secure way? It seems like via this way, when I move the b.php to other upper level folder, I don't need to do any changes to the include file path, which is good for maintenance. Any cons? Like SEO wise, or any other reason... What you guys think.
