  • Javascript array of href's

    - by Jason
    Hi, I am trying to create an array with different href's to then attach to 5 separate elements. This is my code: var link = new Array('link1', 'link2', 'link3', 'link4', 'link5'); $(document.createElement("li")) .attr('class',options.numericId + (i+1)) .html('<a rel='+ i +' href=\"page.php# + 'link'\">'+ '</a>') .appendTo($("."+ options.numericId)) As you can see I am trying to append these items from the array to the end of my page so each link will take the user to a different section of the page. But i have not been able to do this. Is there a way to to create elements with different links? I am new to javascript so I am sorry if this doesn't make a whole lot of sense. If anyone is confused by what i am asking here I can try to clarify if I get some feedback. Any solutions would be greatly appreciated. Thanks, jason

  • VS2008 Complains about css class names it should know about

    - by Matt Dawdy
    I've seen this in a webcast somewhere, but I can't remember where, and all searching terms I'm trying are coming up unhelpful. I've got a stylesheet for my site, and it's referenced in a master page. Child pages that use this master page use these styles, but .Net doesn't know about them. When the site is run, it all works great, but I'm trying to figure out how to get .Net to know about them at design time. This should also fix the issue with not knowing about the javascript files I'm including, too -- I think it's all related and I can't for the life of me figure out how.

  • wget not behaving via IPC::Open3 vs bash

    - by Ryley
    I'm trying to stream a file from a remote website to a local command and am running into some problems when trying to detect errors. The code looks something like this: use IPC::Open3; my @cmd = ('wget','-O','-','http://10.10.1.72/index.php');#any website will do here my ($wget_pid,$wget_in,$wget_out,$wget_err); if (!($wget_pid = open3($wget_in,$wget_out,$wget_err,@cmd))){ print STDERR "failed to run open3\n"; exit(1) } close($wget_in); my @wget_outs = <$wget_out>; my @wget_errs = <$wget_err>; print STDERR "wget stderr: ".join('',@wget_errs); #page and errors outputted on the next line, seems wrong print STDERR "wget stdout: ".join('',@wget_outs); #clean up after this, not shown is running the filtering command, closing and waitpid'ing When I run that wget command directly from the command-line and redirect stderr to a file, something sane happens - the stdout will be the downloaded page, the stderr will contain the info about opening the given page. wget -O - http://10.10.1.72/index.php 2> stderr_test_file When I run wget via open3, I'm getting both the page and the info mixed together in stdout. What I expect is the loaded page in one stream and STDERR from wget in another. I can see I've simplified the code to the point where it's not clear why I want to use open3, but the general plan is that I wanted to stream stdout to another filtering program as I received it, and then at the end I was going to read the stderr from both wget and the filtering program to determine what, if anything went wrong. Other important things: I was trying to avoid writing the wget'd data to a file, then filtering that file to another file, then reading the output. It's key that I be able to see what went wrong, not just reading $? 8 (i.e. I have to tell the user, hey, that IP address is wrong, or isn't the right kind of website, or whatever). Finally, I'm choosing system/open3/exec over other perl-isms (i.e. backticks) because some of the input is provided by untrustworthy users.

  • Can I encrypt value in C# and use that with SQL Server 2005 symmetric encryption?

    - by Robert Byrne
    To be more specific, if I create a symmetric key with a specific KEY_SOURCE and ALGORITHM (as described here), is there any way that I can set up the same key and algorithm in C# so that I can encrypt data in code, but have that data decrypted by the symmetric key in Sql Server? From the research I've done so far, it seems that the IDENTITY_VALUE for the key is also baked into the cypher text, making things even more complex. I'm thinking about just trying all the various ways I can think of, ie hashing the KEY_SOURCE using different hash algorithms for a key and trying different ways of encrypting the plain text until I get something that works. Or is that just futile? Has anyone else done this, any pointers? UPDATE Just to clarify, I want to use NHibernate on the client side, but theres a bunch of stored procedures on the database side that still perform decryption.

  • using sqlite3 with lua

    - by mr calendar
    I'm trying to use sqlite3 with lua (am already using c++, but I'm a n00b with lua- I read this) but I'm getting the following when trying to build the library or whatever: C:\lib\lsqlite3-7>mingw32-make process_begin: CreateProcess(NULL, pkg-config --version, ...) failed. makefile:53: *** windows32. Stop. I'm not at all surprised at a makefile failing but I can't do them (is it spaces or tabs? where is it they have to go?), I would have thought there was a binary for windows? Any simple answers appreciated. I haven't got the time to learn make or install cygwin or whatever.

  • C# how to wait for a webpage to finish loading before continuing

    - by MD6380
    I'm trying to create a program to clone multiple bugs at a time through the web interface of our defect tracking system. How can I wait before a page is completely loaded before I continue? //This is pseudo code, but this should give you an idea of what I'm trying to do. The //actual code uses multi-threading and all that good stuff :). foreach (string bug in bugs) { webBrowser.Navigate(new Uri(url)); webBrowser.Document.GetElementById("product").SetAttribute("value", product); webBrowser.Document.GetElementById("version").SetAttribute("value", version); webBrowser.Document.GetElementById("commit").InvokeMember("click"); //Need code to wait for page to load before continuing. }

  • Sending Back Ajax variable

    - by matthewb
    Hello, I am trying to use jquery to do a client side validation to do a check and return with a error or success. I know how to echo text/html back as the response, but here's what I am trying to do. On Error, send back a message, so the user can re-submit a form. On Success, re-load the page. I am not sure how to get it to send a variable which I think will let me do either condition in jquery. Any suggestions??

  • ASP.NET MVC: Problem generating thumbnails...need help!

    - by Ryan Pitts
    Ok, so i'm new to asp.net mvc and i'm trying to make a web application photo gallery. I've posted once on here about this issue i am having of trying to generate thumbnails on-the-fly on the page instead of the actual full-size images. Basically, the functionality i am looking for is to be able to have thumbnails on the page and then be able to click the images to see the full-size version. I am pulling the images and images info from an XML file. So, i did this so i could display them dynamically and so it would be easier to make changes later. Later, i am going to add functionality to upload new images to specific galleries (when i figure out how to do that as well). I am providing a link to download the project i am working on so you can see the code. I would appreciate any help with this! Thanks! URL to project: http://www.diminished4th.com/TestArtist.zip Ryan

  • Use eval to set unknown property in Python

    - by Mahi
    I have an User class, that has multiple properties inside it, and I also have addPoint method for User class, which allows user to input points into any of it's properties. However, there can be up to like 500 properties, everyone can have different ones, etc. So it would be a pain in the ass to code every property with "if: - elif:". Now this is what I tried to do, to make it much easier and cleaner: class User: def __init__(self): self.health = 0 self.speed = 0 def addPoint(self, property, amount): eval("self."+property) = eval("self."+property) + amount And now when I'd do fe. u = User() u.addPoint("health", 5) I would like it to do this: self.health = self.health + 5, and that's what I used the eval()s for. However, Python's just giving me error: can't assign to function call. I'm not trying to assign the eval() function call itself, I'm trying to assign the returned value from eval(), so how could I do this the easiest way?

  • initWithCoder works, but init seems to be overwriting my objects properties?

    - by Zigrivers
    Hi guys, I've been trying to teach myself how to use the Archiving/Unarchiving methods of NSCoder, but I'm stumped. I have a Singleton class that I have defined with 8 NSInteger properties. I am trying to save this object to disk and then load from disk as needed. I've got the save part down and I have the load part down as well (according to NSLogs), but after my "initWithCoder:" method loads the object's properties appropriately, the "init" method runs and resets my object's properties back to zero. I'm probably missing something basic here, but would appreciate any help! My class methods for the Singleton class: + (Actor *)shareActorState { static Actor *actorState; @synchronized(self) { if (!actorState) { actorState = [[Actor alloc] init]; } } return actorState; } -(id)init { if (self = [super init]) { NSLog(@"New Init for Actor started...\nStrength: %d", self.strength); } return self; } -(id)initWithCoder:(NSCoder *)coder { if (self = [super init]) { strength = [coder decodeIntegerForKey:@"strength"]; dexterity = [coder decodeIntegerForKey:@"dexterity"]; stamina = [coder decodeIntegerForKey:@"stamina"]; will = [coder decodeIntegerForKey:@"will"]; intelligence = [coder decodeIntegerForKey:@"intelligence"]; agility = [coder decodeIntegerForKey:@"agility"]; aura = [coder decodeIntegerForKey:@"aura"]; eyesight = [coder decodeIntegerForKey:@"eyesight"]; NSLog(@"InitWithCoder executed....\nStrength: %d\nDexterity: %d", self.strength, self.dexterity); [self retain]; } return self; } -(void) encodeWithCoder:(NSCoder *)encoder { [encoder encodeInteger:strength forKey:@"strength"]; [encoder encodeInteger:dexterity forKey:@"dexterity"]; [encoder encodeInteger:stamina forKey:@"stamina"]; [encoder encodeInteger:will forKey:@"will"]; [encoder encodeInteger:intelligence forKey:@"intelligence"]; [encoder encodeInteger:agility forKey:@"agility"]; [encoder encodeInteger:aura forKey:@"aura"]; [encoder encodeInteger:eyesight forKey:@"eyesight"]; NSLog(@"encodeWithCoder executed...."); } -(void)dealloc { //My dealloc stuff goes here [super dealloc]; } I'm a noob when it comes to this stuff and have been trying to teach myself for the last month, so forgive anything obvious. Thanks for the help!

  • How can I capture the keystroke that triggers "CellEndEdit" on a DataGridView in C#?

    - by Andy Stampor
    I have a DataGridView that is set to EditOnF2. I do some special processing of data in the CellEndEdit eventhandler that sets the value of the cell. I still want the functionality of the EditOnKeystrokeOrF2 of reverting to the original value when the Esc key is pressed. Unfortunately, at the CellEndEdit eventhandler, I don't see a way to tell what caused the CellEndEdit event to be fired. I only want to change the value of the cell if the Esc key is not pressed. How can I tell if it was or not? Edit: It is worth noting that the KeyDown event does not get fired when the cell is being edited, nor for the final ending keystroke. Edit2: I have tried the KeyPreview suggestion, but the form still does not capture the Escape key being pressed. Edit3: I've been experimenting with trying to get this working. I originally posted some of the following as a separate post, but feel it might be more relevant to include it here. I have a cell in a DataGridView that is now set to EditProgrammatically. To capture the keystroke that starts an edit, I am setting the cell.Value equal to the keystroke. However, this ruins the "Escape" functionality of the cell - when you press escape, instead of reverting to the original value, it reverts to the keystroke that I programmatically inserted into the cell. I believe that if I could set the "EditedFormattedValue" on a cell, this would be where I want to put my keystroke value, however this appears to be read only. How can I accomplish what I am attempting? An example to clarify: If the cell has a value of "54.3" in it, and I press the "9" key, it begins editing the cell and places a "9" there. If I hit Escape, instead of reverting to "54.3" it reverts to "9". What I want is for it to return to its original value of "54.3". So, I am trying to tackle this issue from both the beginning and the end. I think the real problem is that I am overwriting the original value and have no way to determine if I should revert it or not. Edit4: It looks like CellValidating might be worth using, but I am seeing strange behavior when I experiment with it. In a new project, I create the DataGridView and register for the various events and see that CellValidating is fired before the CellEndEdit. However, in my project where I am trying to get this to work, CellEndEdit is firing BEFORE CellValidating. Any ideas on what the difference might be?

  • streaming XML serialization in .net

    - by Luca Martinetti
    Hello, I'm trying to serialize a very large IEnumerable<MyObject> using an XmlSerializer without keeping all the objects in memory. The IEnumerable<MyObject> is actually lazy.. I'm looking for a streaming solution that will: Take an object from the IEnumerable<MyObject> Serialize it to the underlying stream using the standard serialization (I don't want to handcraft the XML here!) Discard the in memory data and move to the next I'm trying with this code: using (var writer = new StreamWriter(filePath)) { var xmlSerializer = new XmlSerializer(typeof(MyObject)); foreach (var myObject in myObjectsIEnumerable) { xmlSerializer.Serialize(writer, myObject); } } but I'm getting multiple XML headers and I cannot specify a root tag <MyObjects> so my XML is invalid. Any idea? Thanks

  • Controlling JIRA via Liferay

    - by Shayan
    I am trying to integrate JIRA into Liferay as a portlet. It seems to be that the best way to do that is using the IFrame portlet. However, there are a few additional things that I need to control. I am trying to model a workflow in JIRA, so depending on what happens within the Liferay portal, Liferay will need to be able to advance the status of tasks in JIRA. In addition, when a task is completed in JIRA, it needs to be able to call back to Liferay and create new users or groups if necessary. Is there some way to integrate JIRA and Liferay so that they can call each others APIs? Thanks.

Obviously it s command line parser but i m trying to understand the syntax so i can actually run the program. This is from commandline-jmxclient , they have no documents on setting JMX properties but in their source code, there is such an option, so i just want to understand how i can invoke that method.

  • Android: Displaying Video on VideoView

    - by AndroidDev93
    I'm trying to display a video in my sdcard on the video view. Here is my code: String name = Environment.getExternalStorageDirectory() + "/test.mp4"; final VideoView videoView = (VideoView)findViewById(R.id.videoView1); videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { public void onPrepared(MediaPlayer arg0) { videoView.start(); } }); videoView.setVideoPath(name); The file I am trying to open is called test.mp4 and its located within the sdcard folder. I get an error saying the application has unfortunately stopped. I would appreciate it if someone could help me. Thanks. EDIT : I used the debugger and found out that I get an InvocationTargetException. The detailed message says that : Failure delivering result ResultInfo{who=null, request=1001, result=-1, data=Intent { dat=file:///mnt/sdcard/test.mp4 }} to activity : java.lang.NullPointerException EDIT : I looked at the logcat again and it seems to give the error at videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { I'm guessing either videoView or MediaPlayer is null.

  • Specialization hierarchy in a domain-model

    - by devoured elysium
    I'm trying to make the domain model of a management system. I have the following kinds of persons in this system: employee manager top mananger I decided to define a User, from where employee, manager and top manager will specialize from. What I don't know is what kind of specialization hierarchy I should choose from. I thought of two ways: or Which might be preferable and why? As a long time coder, every time I try to do a domain-model, I have to fight against the idea of trying to think in how I'm going to code this. From what I've understood, I should not think about those matters in the domain-model, only in object relationships. I don't have to think of code duplication or any of these kind of details here, so I can't really pick any of the options over the other. Thanks

  • Need help making row of buttons consistent

    - by oliverghingold
    I'm making my first website, and I'm trying to make variable-sized buttons so they'll render correctly on low resolution (read: mobile) browsers. Currently I just have the usual rollover image solution (185 pixels wide by 37 tall if anybody cares), but when I preview the site in low resolution it looks, predictably enough, like complete crap (more specifically they don't have room so they arrange vertically instead of horizontally and take up a huge amount of screen real estate). Semi-related, is there a way to overlay text on a button without saving separate images, each with the correct text? Just using a single template for buttons and then deciding what text goes on it as it's needed? tl;dr: I'm trying to get a horizontal lineup of buttons for navigating my website, but I'm a noob and I can't do it right without your generous assistance.

  • JQUERY nav problem

    - by turborogue
    This is part 2 of a different problem that I was having... Hopefully this is about as simple as you can get, but I'm clearly missing something..... The gist is, I'm trying to get a mouseover effect using jquery/css with a mix of background images and colors. It's mostly there, but the issue that I'm having at the moment is, I mouseover the main nav = fine, I mouseover the subnav = fine, I mouse BACK over to that same main nav element, and it's OFF state kicks in instead of remaining ON as it's supposed to... I pasted my code here (since it's kinda long, and apparently I can only paste one link....) http://tinypaste.com/2222e -- a link to my most recent efforts is at the bottom of that pastebin -- hopefully the gist of what I'm trying to do will be clear. I'll keep plugging away for a while, but any help would be greatly appreciated!!:)

  • How do I check if a SQL Server 2005 TEXT column is not null or empty using LINQ To Entities?

    - by emzero
    Hi there guys I'm new to LINQ and I'm trying to check whether a TEXT column is null or empty (as String.IsNullOrEmpty). from c in ... ... select new { c.Id, HasBio = !String.IsNullOrEmpty(c.bio) } Trying to use the above query produces an SqlException: Argument data type text is invalid for argument 1 of len function. The SQL generated is similar to the following: CASE WHEN ( NOT (([Extent2].[bio] IS NULL) OR (( CAST(LEN([Extent2].[bio]) AS int)) = 0))) THEN cast(1 as bit) WHEN (([Extent2].[bio] IS NULL) OR (( CAST(LEN([Extent2].[bio]) AS int)) = 0)) THEN cast(0 as bit) END AS [C1] LEN is not applicable to TEXT columns. I know DATALENGTH should be used for them... How can I force LINQ to produce such thing? Or any other workaround to test if a text column is null or empty??? Thanks!

  • get height on a block of latex output

    - by georg raba
    Hello, I am trying to determine how to get the height on a block of latex output (not the whole document, and not the code..but rather a block of output). As an example of what I am trying to accomplish: i were to have the latex code $\sum_{i=0}^\infty \frac{1}{n}\infty$ \newline hello world \newline hello universe its output would be something like 2 inches high. Of course, the height of the above block of text is dependent on a number of things-font, margin size, etc, as changing any of these parameters changes how many inches that output would be. Is there a command/package that does this? Thanks in advance! Georg Raba
