  • Jquery Exclude a Selector?

    - by Wes
    I've got a form that I clear on focus. I've selected the whole form and it works great except that the submit button goes blank when I click it. how can I exclude my input of input#submit from the following code? $(".wpcf7-form input, .wpcf7-form textarea").focus(function() { if( this.value == this.defaultValue ) { this.value = ""; $(this).addClass('filled'); } }).blur(function() { if( !this.value.length ) { this.value = this.defaultValue; $(this).removeClass('filled'); } });

  • Downloading file with ";" or "#" in file name ruins filename

    - by Sergej Andrejev
    I have a file named AttachmentDownload.aspx and inside Page_Load method have such code wich offers to download file. All names work correctly in IE except names which include ";" or "#". They offer user to save the file under name "AttachmentDownload.aspx". Is there a workaround for this? Here is an example: var fileName = Server.UrlPathEncode (";%.txt"); Response.AddHeader("content-disposition", String.Format("attachment;filename=\"{0}\"", fileName)); Response.WriteFile(path); Response.End();

  • Breakpoint when variable takes on a certain value.

    - by Mick
    I have something analogous to the following code... void function(int x) { // complicated operation on x blah blah } It all appears to be working fine except when x happens to be a particular value, say "273". But x being 273 is a rare event, 99.999% of the time it is some other value. Now I wish to observe the events when this function is called with x=273, so I would like to insert a breakpoint that gets hit only with x is that value. Perhaps I could do it like this: void function(int x) { if (x == 273) { // put breakpoint on this line. } // complicated operation on x blah blah } The problem is that presumably the compiler will optimise away this "if" statement because it doesn't do anything. So my question is what should I put within the "if" statement to to make sure it gets compiled in to something... or should I be tracing the x==273 case in some completely different way.

  • Making a video with opencv and ffmpeg. How to find the right color format?

    - by luc
    I have a webcam video recorder program built with python, opencv and ffmpeg It works ok except that the color of the video is more blue than the reality. The problem seems to come from color format of images. It seems that OpenCv is giving BGR images and ffmpeg+libx264 is expecting YUV420p. I've read that YUV420p correspond to YCbCr. opencv has no conversion from BGR to YCbCr. It only has a conversion to YCrCb. I have made some searchs and tried different alternatives to try converting opencv image to something that could be ok for ffmpeg+libx264. None is working. At this point, I am a bit lost and I would appreciate any pointer that could help me to fix this color issue.

  • Can I change the database server and database a report is pointing to dynamically?

    - by Randy Minder
    I have a Crystal 2008 report that will be deployed to an InfoView server. There are four different databases the user might want to execute the report against. Each of the four databases have exactly the same schema. Only the data in each is different. Each database corresponds to a plant we have around the world. Instead of creating four different reports (each one connected to one of the four databases), am I able to dynamically change the server/database the report hits based on a value the user enters into a parameter? I'm really trying to avoid having to create four identical reports except for the database connection on each. If this isn't possible, how do developers typically deal with this sort of scenario? I would imagine it's fairly common. Thanks very much.

  • Java multidimensional array and scanner novice Q

    - by Max
    I'm new to Java and trying to in essence implement a grid with a character, and if the user inputs 'w' 'a' 's' or 'd' the character moves up/down/left/right within the plane. I created a multidimensional array sized 10x10 public static String[][] grid = new String[10][10]; And then just used a for loop to print "*"s in a 10x10 grid, except for grid[a][b] which is equal to character "A" i.e. my thing to be moved around. That seemed to work alright, then I needed to detect the 'wasd' input from the user so I set up a: Scanner in = new Scanner (System.in); while (in.hasNext()) And I had then: String s = in.next(); char ch = s.charAt(0); switch (ch) but I couldn't make this work, and it wasn't because I didn't complete the "switch" statement, I did, I just see it void copying and pasting the entire thing. I'm sure its incredibly easy slight thing I am missing, can you please point it out for me?

  • Testing methods called on yielded object

    - by Todd R
    I have the following controller test case: def test_showplain Cleaner.expect(:parse).with(@somecontent) Cleaner.any_instance.stubs(:plainversion).returns(@returnvalue) post :showplain, {:content => @somecontent} end This works fine, except that I want the "stubs(:plainversion)" to be an "expects(:plainversion)". Here's the controller code: def showplain Cleaner.parse(params[:content]) do | cleaner | @output = cleaner.plainversion end end And the Cleaner is simply: class Cleaner ### other code and methods ### def self.parse(@content) cleaner = Cleaner.new(@content) yield cleaner cleaner.close end def plainversion ### operate on @content and return ### end end Again, I can't figure out how to reliably test the "cleaner" that is made available from the "parse" method. Any suggestions?

  • MySQL join headaches, please help!

    - by Andrew Heath
    Ok, I've hit the wall here and need some help. Sample tables are as follows: SCENARIO_NATIONS [scenID] [side] [nation] scen001 1 Germany scen001 2 Britain scen001 2 Canada SCENARIO_NEEDUNITS [scenID] [unitID] scen001 0001 scen001 0003 scen001 0107 scen001 0258 scen001 0759 UNIT_BASIC_DATA [unitID] [nation] [name] 0001 Germany Mortars 0003 Germany Infantry 0107 Britain Lt 0258 Britain Infantry 0759 Canada Kilted Yaksmen Goal: given a scenID, pull a list of units from the database sorted by side, nation, name. I can do everything except for the side inclusion with: SELECT scenario_needunits.scenID, unit_basic_data.nation, unit_basic_data.name FROM scenario_needunits LEFT OUTER JOIN unit_basic_data ON scenario_needunits.unitID=unit_basic_data.unitID WHERE scenario_needunits.scenID='scen001' ORDER BY unit_basic_data.nation ASC, unit_basic_data.name ASC I've tried just dropping the SCENARIO_NATIONS table in as a LEFT OUTER JOIN on scenID but what ends up happening is that ALL units come back with a side of 1 because that's always the first side listed for the scenID in the SCENARIO_NATIONS table. Conceptually, what I think needs to happen is SCENARIO_NATIONS must be joined to both the scenID (to restrict it to just that scenario) and to each unit's nation but I don't have any idea how to do that and my Google-fu is inadequate. :-/

  • Problem with TabHost UI layout.

    - by Alan B
    What I'm trying to do is create a layout like this: +--------+ Search |EditText| [Button] +--------+ +---------+ |Tab 1 |---------+ | |Tab 2 | |---------+---------+-----------------+ | ListView Item 1 | | ListView Item 2 | | ListView Item 3 | | ListView Item 4 | | ListView Item 5 | | ListView Item 6 | | ListView Item 7 | | ListView Item 8 | | ListView Item 9 | | ListView Item 10 | +-------------------------------------+ So that's a TextView saying 'Search', an EditText and a button. Then below it the tabs - Tab 1 has a ListView, Tab 2 some other stuff. I can get a simple TabHost setup with two tabs working fine but can't get the above to lay out properly. Any hints ? I'd create the UI in the Eclipse designer and check the XML from that, except the designer doesn't work with TabHost. And DroidDraw doesn't seem to know about TabHost.

  • C++: How would I get unix time?

    - by John D.
    I need a function or way to get the UNIX epoch in seconds, much like how I can in PHP using the time function. I can't find any method except the time() in ctime which seems to only output a formatted date, or the clock() function which has seconds but seems to always be a multiple of 1 million, nothing with any resolution. I wish to measure execution time in a program, I just wanted to calculate the diff between start and end; how would a C++ programmer do this? EDIT: time() and difftime only allow resolution by seconds, not ms or anything too btw.

  • mocking static method call to c# library class

    - by Joe
    This seems like an easy enough issue but I can't seem to find the keywords to effect my searches. I'm trying to unit test by mocking out all objects within this method call. I am able to do so to all of my own creations except for this one: public void MyFunc(MyVarClass myVar) { Image picture; ... picture = Image.FromStream(new MemoryStream(myVar.ImageStream)); ... } FromStream is a static call from the Image class (part of c#). So how can I refactor my code to mock this out because I really don't want to provide a image stream to the unit test.

    Hi, I wrote a little search script for a client, it works and words get highlited, BUT... Imagine this situation: search term: test found result: Hello this <a href="/news/this-is-a-test">is a test</a> In this example both 'test' in the href part and between the <a> tags get highlited, breaking the link. How could I prevent this? Edit: So this is what I need: A regex replace function that replaces all matched search strings EXCEPT the ones that are located inside a href attribute Greets, nick

  • Writing secure java code with RMI

    - by jtnire
    Hi Everyone, This may seem like a very broad question, but any help is appreciated. I have a client/server solution written in java which uses the Cajo project (which uses RMI). I just want to try and make my solution as secure as possible, given the sensitive data that will be transferred between server and client. So far, my ideas are to make all my classes "final" as well as throw a "non-serializable" exception for all my classes in the server (except for the object bound in the RMI registry, and any objects that actually do need to be transferred of course). Can anyone think of any other ideas? I know that someone could write a malicious client - this isn't hard to do as you can find out the remote object's API using reflection. However is there anything I can do to protect a malicious client access classes/objects within the server that they are not supposed to access? Many Thanks

  • Can Uploadify send e-mail on complete?

    - by David
    Uploadify is a jQuery/Flash plugin for uploading multiple files. It's working great, except I can't figure out how trigger e-mail when all files are complete. If I try to add something like <% SendEmail(); %> to the onAllComplete parameter, it just sends the e-mail when the page loads. Is there a way to do this within the handler recommended here or from this post? Or is there some way to trigger a post in the onAllComplete parameter?

  • How do I make an About window the front-most window in a Cocoa application with no UI?

    - by mipadi
    I'm building a Cocoa application that runs as an item in the status bar. This application has an About window and an item to activate that about window, using the standard Cocoa mechanism for doing so (-[NSApplication orderFrontStandardAboutPanel:]). Naturally this is all hooked up automagically. It works great except for one thing: unlike most About windows, it shows up underneath all other windows, rather than on top. I believe this is because the application does not have a UI, so all its windows are automatically beneath other windows. Is there a way I can hook into the NSApplication mechanism for displaying the About window so I can send it to the front? I've poked around in the docs for NSApplication, but there's no way to get a reference to the About window that I can see so that I can make it appear on top.

  • Inherit appenders from calling instance in log4j or logback

    - by Lord.Quackstar
    In my program I have 2 separate streams of logging events (calling them streams for simplicity, in reality its 2 appenders). Stream1 contains client logging and Stream2 contains control logging. Now this might seem easy, except that certain classes can be both in the client logging and server logging, depending on the situation. Complicating this further is the fact that a command that a client wants takes place in 2 separate threads (one being fetched randomly from a thread pool), so any kind of tracking with MDC or NDC isn't possible. What would really simplify this is if the logger could inherit the appenders from the calling instance. That way I can setup 2 appenders for 2 loggers and be done. However I have no idea how to do it cleanly or easily. Can anyone offer any advice on how to do so? Note: If something needs to be passed around, I do have a event bean that gets passed to everything in the chain that can be used if necessary.

  • Handling Timeouts In A Website SQLCommand Object and c#

    - by user341684
    I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ... Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page. The error is not consistent nor is the time the page has to stay idle in order for it to occur.... The current sql command object timeout is 30 secs and the website timeout is 30 minutes. Has anyone else experienced this scenario and what is the fix as I would not except anything to go out of scope until the website timeout occurs ... Any insight will be appreciated.

  • concatenating results from SQL query and NULL columns

    - by Curtis
    I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows: SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo FROM Users WHERE (CustomerNum = @CustomerNum) ORDER BY UserName I then set 'UserInfo' as the text field in the dropdownlist. This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist. Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event? Thanks

  • NetNamedPipe: varying response time when communication is idling

    - by Sven Künzler
    I have two WCF apps communicating one-way over named pipes. All is nice, except for one thing: Normally, the request/response cycle takes zero (marginal) time. However, if there was a time span of, say, half a minute without any communication, the request/response increases up to ~300-500ms. I looked around the net and I got the idea of using a heart beat/ping mechanism to keep the communication channel busy. Using trial and error I found that when doing a request each 10 seconds, the response times stay low. Starting at around 15s intervals, the "hiccup" response times begin to appear. Now I'm wondering where this phenomenon is originating from. I tried setting alle conceivable timeouts on both sides to 1 minute, but that did not help. Can anybody explain what's going on there?

  • Given a few strings, how many strings can be lexicographically least by modifying the alphabet?

    - by Jackson W
    Number of strings can be huge as in 30000. Given N strings, output which ones can be lexicographically least after modifying the english alphabet. e.g. acdbe...... for example if the strings were: omm moo mom ommnom "mom" is already lexicographically least with the original english alphabet. we can make the word "omm" least by switching "m" and "o" in the alphabet ("abcdefghijklonmpqrstuvwxyz"). the other ones you cant make lexicographically last, no matter what you do. any fast way to do this? I have no ways to approach this except try every single possible alphabet

  • How do you convert date taken from a bash script to milliseconds in java program?

    - by Matt Pascoe
    I am writing a piece of code in java that needs to take a time sent from a bash script and parse the time to milliseconds. When I check the millisecond conversion on the date everything is correct except for the month I have sent which is January instead of March. Here is the variable I create in the bash script, which later in the script I pass to the java program: TIME=`date +%m%d%Y_%H:%M:%S` Here is the java code which parses the time to milliseconds: String dt = "${scriptstart}"; java.text.SimpleDateFormat scriptStart = new java.text.SimpleDateFormat("MMDDyyyy_HH:mm:ss"); long start = scriptStart.parse(dt).getTime(); The goal of this statement is to find the elapsed time between the start of the script and the current system time. To troubleshoot this I printed out the two: System Time = 1269898069496 (converted = Mon Mar 29 2010 16:27:49 GMT-0500 (Central Daylight Time)) Script Start = 03292010_16:27:45 Script Start in Milli = 1264804065000 (Converted = Fri Jan 29 2010 16:27:45 GMT-0600 (Central Standard Time))

  • How to Get Search Bar in Tableview to Appear When User Taps Search Icon at the top of sectionIndex s

    - by Gorgando
    I have a tableview with an indexed scrollbar on the right side that shows the letters A-Z and has a magnifying glass icon at the top ({search}). All of the letters in the scrollbar appropriately take the user to the corresponding section except for the magnifying glass, which takes the user to "A" and keeps the searchBar hidden. I just want it to go to the very top of the table so that the searchBar shows up when the user taps the magnifying glass icon in the scroll bar. I've been looking all over for ways to do this, but I can't find any way shy of adding the searchBar to the first tableCell and it's own section, which I'd prefer not to do unless it's the only way. Thanks so much!
