  • Get HTML element informations in .NET

    - by martin.malek
    Hi, I'm just thinking if there is any way how to get information about element in HTML in my .NET application. The input is HTML page and path to CSS files etc. I want to take e.g. H1 tag and found what will be the CSS for it. Is there any code or can I use IE and try to take this information from it automatically inside of my application?

  • NAN mixing float and GLFloat?

    - by carrots
    This often returns NAN ("Not A Number") depending on input: #define PI 3.1415f GLfloat sineEaseIn(GLfloat ratio) { return 1.0f-cosf(ratio * (PI / 2.0f)); } I tried making PI a few digits smaller to see if that would help. No dice. Then I thought it might be a datatype mismatch, but float and glfloat seem to be equivalent: gl.h typedef float GLfloat; math.h extern float cosf( float ); Is this a casting issue?

  • Pylons error handling

    - by TJ Huffington
    Hello, I am just getting started with Pylons and am confused as to how to account for exceptions. What is the proper way to error check user input (ensure a correct email address, check that it doesn't yet exist in the database, etc ...)? Should these checks go inside the model classes or somewhere else? Sample code would be great.

  • XPATH: multiple negations in for-each

    - by Peter
    I have the following simplified XML: <?xml version="1.0" encoding="UTF-8" ?> <MATMAS05> <IDOC BEGIN="1"> <E1MARAM SEGMENT="1"> <MSGFN>005</MSGFN> <MATNR>000000000000401436</MATNR> <E1MARCM SEGMENT="1"> <MSGFN>005</MSGFN> <WERKS>A120</WERKS> <MMSTA>01</MMSTA> </E1MARCM> <E1MVKEM SEGMENT="1"> <VKORG>0120</VKORG> <VMSTA>04</VMSTA> </E1MVKEM> </E1MARAM> </IDOC> </MATMAS05> If <WERKS>=A120 and <MMSTA> is NOT '01' or '02' or '03' OR if <VKORG>=0120 and <VMSTA> is NOT '01' or '02' or '03' then the <MATNR> should be mapped to the target XML. I came up with the following XSLT: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output encoding="UTF-8" method="xml" indent="yes"/> <xsl:template match="/*"> <xsl:for-each select="IDOC[(E1MARAM/E1MVKEM[VKORG='0120'][not(VMSTA='01' or VMSTA='02' or VMSTA='03')]) or (E1MARAM/E1MARCM[WERKS = 'A120'][not(MMSTA='01' or MMSTA='02' or MMSTA='03')])]"> <Item> <ITEM_CODE> <xsl:value-of select="E1MARAM/MATNR"/> </ITEM_CODE> </Item> </xsl:for-each> </xsl:template> </xsl:stylesheet> But if I apply that XSLT I get the following unwanted output (because <MMSTA>='01'): <?xml version="1.0" encoding="UTF-8"?> <Item> <ITEM_CODE>000000000000401436</ITEM_CODE> </Item> How can I solve this? I have tried around with that XPATH expression but I can't get the wanted result. What am I doing wrong in my XPATH? Thank you for any ideas with this. Best regards, Peter

  • HelloWebView Sample: now using SDK 3 and getting killed

    - by Tim
    Hey Folks, Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder. Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed. Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator? The main.xml, manifest, and console output are below. Let me know if you need more information.

  • Calling Java from Python

    - by roddik
    Hello. I have a Java app that takes pretty much time to be initialized (so I can't use command-line like interface) and I need to pass text and receive the output of a Java method from Python. Is it possible to load the Java application, have it opened all the time the Python script runs and use a method from that app?

  • Asp.Net MVC Not Duplicate forms when Edit/Add

    - by Pino
    When we have anything that requires user input (Eg adding a product to a database) the Edit screen looks the same as the add screen. When using MVC .Net how do you handle this? Do you return the same view? Just adjust the model to reflect the change?

  • In paragraph form field with label underneath

    - by aslum
    I'd like to have an input box in the middle of a paragraph, with the label in smaller text underneath it. Kind of like: Hello [________________], This is to inform you (Customer Name) that the [____________] you ordered is no longer (Item Name) available. I thought it would be pretty easy to do, but my brain doesn't appear to be working today. Is it possible to do this with just CSS, and in a simple enough manner that it can be adapted to different forms easily?

  • Wordpress as CMS, Without Using It As Website Platform

    - by swt
    What is the best method, if there is one, of using Wordpress as a CMS for users to input data while not actually building the website on the Wordpress platform? One possible solution I've found is using a PHP class called "WPGet" (http://peter.upfold.org.uk/projects/wpget) which fetches directly from the database.

  • IP address numbers in MySQL subquery

    - by Iain Collins
    I have a problem with a subquery involving IPV4 addresses stored in MySQL (MySQL 5.0). The IP addresses are stored in two tables, both in network number format - e.g. the format output by MySQL's INET_ATON(). The first table ('events') contains lots of rows with IP addresses associated with them, the second table ('network_providers') contains a list of provider information for given netblocks. events table (~4,000,000 rows): event_id (int) event_name (varchar) ip_address (unsigned 4 byte int) network_providers table (~60,000 rows): ip_start (unsigned 4 byte int) ip_end (unsigned 4 byte int) provider_name (varchar) Simplified for the purposes of the problem I'm having, the goal is to create an export along the lines of: event_id,event_name,ip_address,provider_name If do a query along the lines of either of the following, I get the result I expect: SELECT provider_name FROM network_providers WHERE INET_ATON('192.168.0.1') >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 SELECT provider_name FROM network_providers WHERE 3232235521 >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 That is to say, it returns the correct provider_name for whatever IP I look up (of course I'm not really using 192.168.0.1 in my queries). However, when performing this same query as a subquery, in the following manner, it doesn't yield the result I would expect: SELECT event.id, event.event_name, (SELECT provider_name FROM network_providers WHERE event.ip_address >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1) as provider FROM events Instead the a different (incorrect) value for network_provider is returned - over 90% (but curiously not all) values returned in the provider column contain the wrong provider information for that IP. Using event.ip_address in a subquery just to echo out the value confirms it contains the value I'd expect and that the subquery can parse it. Replacing event.ip_address with an actual network number also works, just using it dynamically in the subquery in this manner that doesn't work for me. I suspect the problem is there is something fundamental and important about subqueries in MySQL that I don't get. I've worked with IP addresses like this in MySQL quite a bit before, but haven't previously done lookups for them using a subquery. The question: I'd really appreciate an example of how I could get the output I want, and if someone here knows, some enlightenment as to why what I'm doing doesn't work so I can avoid making this mistake again. Notes: The actual real-world usage I'm trying to do is considerably more complicated (involving joining two or three tables). This is a simplified version, to avoid overly complicating the question. Additionally, I know I'm not using a between on ip_start & ip_end - that's intentional (the DB's can be out of date, and such cases the owner in the DB is almost always in the next specified range and 'best guess' is fine in this context) however I'm grateful for any suggestions for improvement that relate to the question. Efficiency is always nice, but in this case absolutely not essential - any help appreciated.

  • How can I create a FreeBSD package using EPM that has the ORIGIN @comment?

    - by Chris R
    I'm building packages of our internal software products using EPM, and over time these packages (of which we have a large number) clutter up the output of pkg_delete and pkg_add with the following general kind of messages: err: pkg_add: package MYPACKAGE has no origin recorded I can see from some old FreeBSD lists that the +CONTENTS file in the package must have a line like this: @comment ORIGIN:some_source_path What I don't see is a way to get this line in place using EPM. Can somebody tell me how to do this?

  • In Ruby, how does coerce() actually work?

    - by Jian Lin
    It is said that when we have a class Point and knows how to perform point * 3 like the following: class Point def initialize(x,y) @x, @y = x, y end def *(c) Point.new(@x * c, @y * c) end end point = Point.new(1,2) p point p point * 3 Output: #<Point:0x336094 @x=1, @y=2> #<Point:0x335fa4 @x=3, @y=6> but then, 3 * point is not understood: Point can't be coerced into Fixnum (TypeError) So we need to further define an instance method coerce: class Point def coerce(something) [self, something] end end p 3 * point Output: #<Point:0x3c45a88 @x=3, @y=6> So it is said that 3 * point is the same as 3.*(point) that is, the instance method * takes an argument point and invoke on the object 3. Now, since this method * doesn't know how to multiply a point, so point.coerce(3) will be called, and get back an array: [point, 3] and then * is once again applied to it, is that true? point * 3 which is the same as point.*(3) and now, this is understood and we now have a new Point object, as performed by the instance method * of the Point class. The question is: 1) who invokes point.coerce(3) ? Is it Ruby automatically, or is it some code inside of * method of Fixnum by catching an exception? Or is it by case statement that when it doesn't know one of the known types, then call coerce? 2) Does coerce always need to return an array of 2 elements? Can it be no array? Or can it be an array of 3 elements? 3) And is the rule that, the original operator (or method) * will then be invoked on element 0, with the argument of element 1? (element 0 and element 1 are the two elements in that array returned by coerce) Who does it? Is it done by Ruby or is it done by code in Fixnum? If it is done by code in Fixnum, then it is a "convention" that everybody follows when doing a coerce? So could it be the code in * of Fixnum do something like this: if (something.typeof? ...) else if ... # other type else if ... # other type else # if it is not a type I know array = something.coerce(self) return array[0].*(array[1]) end

  • Sending STDERR to logger

    Im writing a bash-script to perform an offsite backup, using rsync over SSH. I'm able to send STDOUT to logger, for logs via rsync --del -az -e 'ssh -i mycrt.crt' /home/gnutt/backup/ me@offisite:backup | logger -i But I want to send STDERR instead, so if there is a problem, such as that offsite is unavailable, that output should be sent to logger and logged.
