  • Having Uploadify e-mail a link to download the file

    - by kwek-kwek
    Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it. I wanted to ask if It is possible to sends out a link of a file that has just been uploaded wioth the e-mail notification of Uploadify. Here is the code for uploadify.php : <?php if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; // $fileTypes = str_replace('*.','',$_REQUEST['fileext']); // $fileTypes = str_replace(';','|',$fileTypes); // $typesArray = split('\|',$fileTypes); // $fileParts = pathinfo($_FILES['Filedata']['name']); // if (in_array($fileParts['extension'],$typesArray)) { // Uncomment the following line if you want to make the directory if it doesn't exist // mkdir(str_replace('//','/',$targetPath), 0755, true); move_uploaded_file($tempFile,$targetFile); echo "1"; // } else { // echo 'Invalid file type.'; // } } //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test email'; //define the message to be sent. Each line should be separated with \n $message = "Hello World!\n\nThis is my first mail."; //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed"; ?>

  • iOS iPad UIActionSheet Issue

    - by hart1994
    I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter. To to this, I have a UIBarButtonItem coded in and when touched, it triggers this: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [sheet addButtonWithTitle:@"Email"]; [sheet addButtonWithTitle:@"Tweet"]; [sheet addButtonWithTitle:@"Cancel"]; sheet.cancelButtonIndex = sheet.numberOfButtons-1; [sheet showFromRect:self.view.bounds inView:self.view animated:YES]; [sheet release]; In conjunction with this to detect which button is selected: clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.cancelButtonIndex) { return; } switch (buttonIndex) { case 0: { [self emailThis]; break; } case 1: { [self tweetThis]; break; } } This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController, but it is positioned center of the navbar with practically no height. I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already. Many thanks, Ryan PS: I'm new to objective-c/iOS coding, so please be specific. Thank you :)

  • Can I embed a custom font in an iPhone application?

    - by Airsource Ltd
    I would like to have an app include a custom font for rendering text, load it, and then use it with standard UIKit elements like UILabel. Is this possible? I found these links: http://discussions.apple.com/thread.jspa?messageID=8304744 http://forums.macrumors.com/showthread.php?t=569311 but these would require me to render each glyph myself, which is a bit too much like hard work, especially for multi-line text. I've also found posts that say straight out that it's not possible, but without justification, so I'm looking for a definitive answer. EDIT - failed -[UIFont fontWithName:size:] experiment I downloaded Harrowprint.tff (downloaded from here) and added it to my Resources directory and to the project. I then tried this code: UIFont* font = [UIFont fontWithName:@"Harrowprint" size:20]; which resulted in an exception being thrown. Looking at the TTF file in Finder confirmed that the font name was Harrowprint. EDIT - there have been a number of replies so far which tell me to read the documentation on X or Y. I've experimented extensively with all of these, and got nowhere. In one case, X turned out to be relevant only on OS X, not on iPhone. Consequently I am setting a bounty for this question, and I will award the bounty to the first person who provides an answer (using only documented APIs) who responds with sufficient information to get this working on the device. Working on the simulator too would be a bonus. EDIT - it appears that the bounty auto-awards to the answer with the highest nunber of votes. Interesting. No one actually provided an answer that solved the question as asked - the solution that involves coding your own UILabel subclass doesn't support word-wrap, which is an essential feature for me - though I guess I could extend it to do so.

  • android compile error: could not reserve enough space for object heap

    - by moonlightcheese
    I'm getting this error during compilation: Error occurred during initialization of VM Could not create the Java virtual machine. Could not reserve enough space for object heap What's worse, the error occurs intermittently. Sometimes it happens, sometimes it doesn't. It seems to be dependent on the amount of code in the application. If I get rid of some variables or drop some imported libraries, it will compile. Then when I add more to it, I get the error again. I've included the following sources into the application in the [project_root]/src/ directory: org.apache.httpclient (I've stripped all references to log4j from the sources, so don't need it) org.apache.codec (as a dependency) org.apache.httpcore (dependency of httpclient) and my own activity code consisting of nothing more than an instance of HttpClient. I know this has something to do with the amount of memory necessary during compile time or some compiler options, and I'm not really stressing my system while i'm coding. I've got 2GB of memory on this Core Duo laptop and windows reports only 860MB page file usage (haven't used any other memory tools. I should have plenty of memory and processing power for this... and I'm only compiling some common http libs... total of 406 source files. What gives?

  • How to deal with calculated values with Dependency Properties on a custom WPF control

    - by jpierson
    To summarize what I'm doing, I have a custom control that looks like a checked listbox and that has two dependency properties one that provides a list of available options and the other that represents a enum flag value that combines the selection options. So as I mentioned my custom control exposes two different DependencyProperties, one of which is a list of options called Options and the other property called SelectedOptions is of a specific Enum type that uses the [Flags] attribute to allow combinations of values to be set. My UserControl then contains an ItemsControl similar to a ListBox that is used to display the options along with a checkbox. When the check box is checked or unchecked the SelectedOptions property should be updated accordingly by using the corresponding bitwise operation. The problem I'm experiencing is that I have no way other than resorting to maintaining private fields and handling property change events to update my properties which just feels unatural in WPF. I have tried using ValueConverters but have run into the problem that I can't really using binding with the value converter binding so I would need to resort to hard coding my enum values as the ValueConverter parameter which is not acceptable. If anybody has seen a good example of how to do this sanely I would greatly appreciate any input. Side Note: This has been a problem I've had in the past too while trying to wrap my head around how dependency properties don't allow calculated or deferred values. Another example is when one may want to expose a property on a child control as a property on the parent. Most suggest in this case to use binding but that only works if the child controls property is a Dependency Property since placing the binding so that the target is the parent property it would be overwritten when the user of the parent control wants to set their own binding for that property.

  • Why does my REST request return garbage data?

    - by Alienfluid
    I am trying to use LWP::Simple to make a GET request to a REST service. Here's the simple code: use LWP::Simple; $uri = "http://api.stackoverflow.com/0.8/questions/tagged/php"; $jsonresponse= get $uri; print $jsonresponse; On my local machine, running Ubuntu 10.4, and Perl version 5.10.1: farhan@farhan-lnx:~$ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi I can get the correct response and have it printed on the screen. E.g.: farhan@farhan-lnx:~$ head -10 output.txt { "total": 1000, "page": 1, "pagesize": 30, "questions": [ { "tags": [ "php", "arrays", "coding-style" (... snipped ...) But on my host's machine to which I SSH into, I get garbage printed on the screen for the same exact code. I am assuming it has something to do with the encoding, but the REST service does not return the character set type in the response, so how do I force LWP::Simple to use the correct encoding? Any ideas what may be going on here? Here's the version of Perl on my host's machine: [dredd]$ perl --version This is perl, v5.8.8 built for x86_64-linux-gnu-thread-multi

  • sIFR3: controlling a and a:hover styles inside replaced through CSS rather than JS

    - by sneeuwitje
    For graceful degrading and minimal coding for the sIFR feature on my websites I would want to define styles in CSS as much as possible. Here's what I do: Define a H3 tag to be replaced by sIFR3. H3 comes in varying colors by CSS depending on it's container, say body.blue-txt h3{ color: #009CDA; } body.white-txt h3{ color: #FFFFFF; } body.etc... H3 might contain an anchor (I'm aware of semantical issues, but that's just how it is ... sorry) With setting sIFR.useStyleCheck = true; sIFR3 will show replaced normal H3 text with correct color, but when it contains a link, it shows the Flash default #0000FF .... All fine; I can tweak e.g. blue text in sifr-config.js by using the css-parameter for sIFR.replace(): sIFR.replace(futura, { selector: 'body.blue-txt h3', css: 'a {color: #009CDA; }, a:hover { color: #009CDA; text-decoration: underline; }' }); But that would have to be coded for every single text-color in my sIFR replacements in both JS and CSS. So I would want to make the sIFR.useStyleCheck setting just respect the CSS in sifr-config.css like: body.blue-txt h3{ color: #009CDA; } body.blue-txt h3 a{ color: #009CDA; } body.blue-txt h3 a:hover{ color: #009CDA; text-decoration: underline; } Only this doesn't seem to work ... the link text keeps popping up as #0000FF and the hover is not underlined. Is this just Not A Feature (Yet), or am doing something wrong?

  • Dojo: dojo onblur events

    - by Jane Wilkie
    Hi guys, I have a form setup with dojo 1.5. I am using a dijit.form.ComboBox and a dijit.form.TextBox The Combobox has values like "car","bike","motorcycle" and the textbox is meant to be an adjective to the Combobox. So it doesn't matter what is in the Combobox but if the ComboBox does have a value then something MUST be filled in the TextBox. Optionally, if nothing is in the ComboBox, then nothing can be in the TextBox and that is just fine. In fact if something isn't in the Combobox then nothing MUST be in the text box. In regular coding I would just use an onBlur event on the text box to go to a function that checks to see if the ComboBox has a value. I see in dojo that this doesn't work... Code example is below... Vehicle: <input dojoType="dijit.form.ComboBox" store="xvarStore" value="" searchAttr="name" name="vehicle_1" id="vehicle_1" /> Descriptor: <input type="text" dojoType="dijit.form.TextBox" value="" class=lighttext style="width:350px;height:19px" id="filter_value_1" name="filter_value_1" /> My initial attempt was to add an onBlur within the Descriptor's <input> tag but discovered that that doesn't work. How does Dojo handle this? Is it via a dojo.connect parameter? Even though in the example above the combobox has an id of "vehicle_1" and the text box has an id of "filter_value_1", there can be numerous comboboxes and textboxes numbering sequentially upward. (vehicle_2, vehicle_3, etc) Any advice or links to resources would be greatly appreciated. Janie

  • Sysdeo Tomcat DevLoader - Hot deploy of java class causes whole application to restart

    - by Gala101
    Hi, I am using sysdeo tomcat plugin 3.2.1 with eclipse 3.5.1 (Galileo) and tomcat 5.5.23 on windows XP. I can get tomcat plugin working in eclipse, and have extracted devloader.zip into [tomcat]\server\classes. I have also updated the context and now it has this entry: <Context path="/myapp1" reloadable="true" docBase="F:\Work\eclipse_workspace\myapp1" workDir="F:\Work\eclipse_workspace\myapp1\work" > <Logger className="org.apache.catalina.logger.SystemOutLogger" verbosity="4" timestamp="true"/> <Loader className="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" useSystemClassLoaderAsParent="false" /> </Context> I have activated devloader (in Project Properties Tomcat Devloader Classpath) and have 'checked' all my classes and jars, I haven't 'checked' commons-loggin.jar jsp-api.jar, servlet-api.jar. So on launching tomcat via the plugin, I can get it running with devloader as shown in eclipse console view [DevLoader] Starting DevLoader [DevLoader] projectdir=F:\Work\eclipse_workspace\myapp1 [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/classes/ [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/lib/activation.jar However, if I even add a single System.out.println into any java file and save it, the whole application gets reloaded (takes ~80 sec) which is as good as stopping/starting tomcat itself. I've tried adding -Xdebug in JAVA_OPTS in the catalina.bat but no luck :( Can you please guide where I may be doing it wrong.. Please note that I can 'redeploy' the whole application on tomcat but that's not what I need, I am looking to be able to make small changes in java classes 'on-the-fly' while coding/debugging without having to wait for complete app restart. Another annoyance is that restarting tomcat/application causes the session/debug progress to be lost.. Can you please guide me how to go about it. PS: I am not using any ant/maven scripts explicitly, just relying on eclipse to do the build for me (which it does).

  • Excel 2003 VBA - Method to duplicate this code that select and colors rows

    - by Justin
    so this is a fragment of a procedure that exports a dataset from access to excel Dim rs As Recordset Dim intMaxCol As Integer Dim intMaxRow As Integer Dim objxls As Excel.Application Dim objWkb As Excel.Workbook Dim objSht As Excel.Worksheet Set rs = CurrentDb.OpenRecordset("qryOutput", dbOpenSnapshot) intMaxCol = rs.Fields.Count If rs.RecordCount > 0 Then rs.MoveLast: rs.MoveFirst intMaxRow = rs.RecordCount Set objxls = New Excel.Application objxls.Visible = True With objxls Set objWkb = .Workbooks.Add Set objSht = objWkb.Worksheets(1) With objSht On Error Resume Next .Range(.Cells(1, 1), .Cells(intMaxRow, intMaxCol)).CopyFromRecordset rs .Name = conSHT_NAME .Cells.WrapText = False .Cells.EntireColumn.AutoFit .Cells.RowHeight = 17 .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With .Rows("1:1").Select With Selection .Insert Shift:=xlDown End With .Rows("1:1").Interior.ColorIndex = 15 .Rows("1:1").RowHeight = 30 .Rows("2:2").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("4:4").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("6:6").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("1:1").Select With Selection.Borders(xlEdgeBottom) .LineStyle = xlContinuous .Weight = xlMedium .ColorIndex = xlAutomatic End With End With End With End If Set objSht = Nothing Set objWkb = Nothing Set objxls = Nothing Set rs = Nothing Set DB = Nothing End Sub see where I am looking at coloring the rows. I wanted to select and fill (with any color) every other row, kinda like some of those access reports. I can do it manually coding each and every row, but two problems: 1) its a pain 2) i don't know what the record count is before hand. How can I make the code more efficient in this respect while incorporating the recordcount to know how many rows to "loop through" EDIT: Another question I have is with the selection methods I am using in the module, is there a better excel syntax instead of these with selections.... .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With is the only way i figure out how to accomplish this piece, but literally every other time I run this code, it fails. It says there is no object and points to the .font ....every other time? is this because the code is poor, or that I am not closing the xls app in the code? if so how do i do that? Thanks as always!

  • CCLabelAtlas setString doesn't update label

    - by JonnyFunFun
    Hello! I have a CCLabelAtlas that I have on a layer to display the current score within my game...the problem that I am having with it is that it does not update when I use [scoreLabel setString:]. Here's how I have it laid out: In the header: @interface GameScene : CCLayer { ... CCLabelAtlas* scoreLabel; } And in the init: scoreLabel = [[CCLabelAtlas alloc] initWithString:@"0" charMapFile:@"scoreCharMap.png" itemWidth:6 itemHeight:8 startCharMap:'.']; [scoreLabel setPosition:ccp(105, 414)]; [self addChild:scoreLabel z: 6]; scoreCharMap.png is a custom map that includes ./0123456789 of my desired font. When the score is changed, I attempt to do this to get the label to update with the current score: NSString* str = [[NSString alloc] initWithFormat:@"%d", [[GameRunner sharedInstance] currentScore]]; [scoreLabel setString: str]; [str release]; [scoreLabel draw]; Problem is that it doesn't ever update - it just sits there and displays 0. I know for a fact due to breakpoints and debugging that setString is being called, and that the string that it should be displaying is correct - but it just doesn't update. Hard-coding the value and saying [scoreLabel setString:@"1234"] does nothing, either. What am I doing wrong here? I am using Cocos2d 0.99 - thanks in advance!

  • What makes these two R data frames not identical?

    - by Matt Parker
    UPDATE: I remembered dput() about the time Sharpie mentioned it. It's probably the row names. Back in a moment with an answer. I have two small data frames, this_tx and last_tx. They are, in every way that I can tell, completely identical. this_tx == last_tx results in a frame of identical dimensions, all TRUE. this_tx %in% last_tx, two TRUEs. Inspected visually, clearly identical. But when I call identical(this_tx, last_tx) I get a FALSE. Hilariously, even identical(str(this_tx), str(last_tx)) will return a TRUE. If I set this_tx <- last_tx, I'll get a TRUE. What is going on? I don't have the deepest understanding of R's internal mechanics, but I can't find a single difference between the two data frames. If it's relevant, the two variables in the frames are both factors - same levels, same numeric coding for the levels, both just subsets of the same original data frame. Converting them to character vectors doesn't help. Background (because I wouldn't mind help on this, either): I have records of drug treatments given to patients. Each treatment record essentially specifies a person and a date. A second table has a record for each drug and dose given during a particular treatment (usually, a few drugs are given each treatment). I'm trying to identify contiguous periods during which the person was taking the same combinations of drugs at the same doses. The best plan I've come up with is to check the treatments chronologically. If the combination of drugs and doses for treatment[i] is identical to the combination at treatment[i-1], then treatment[i] is a part of the same phase as treatment[i-1]. Of course, if I can't compare drug/dose combinations, that's right out.

  • Array: mathematical sequence

    - by VaioIsBorn
    An array of integers A[i] (i 1) is defined in the following way: an element A[k] ( k 1) is the smallest number greater than A[k-1] such that the sum of its digits is equal to the sum of the digits of the number 4* A[k-1] . You need to write a program that calculates the N th number in this array based on the given first element A[1] . INPUT: In one line of standard input there are two numbers seperated with a single space: A[1] (1 <= A[1] <= 100) and N (1 <= N <= 10000). OUTPUT: The standard output should only contain a single integer A[N] , the Nth number of the defined sequence. Input: 7 4 Output: 79 Explanation: Elements of the array are as follows: 7, 19, 49, 79... and the 4th element is solution. I tried solving this by coding a separate function that for a given number A[k] calculates the sum of it's digits and finds the smallest number greater than A[k-1] as it says in the problem, but with no success. The first testing failed because of a memory limit, the second testing failed because of a time limit, and now i don't have any possible idea how to solve this. One friend suggested recursion, but i don't know how to set that. Anyone who can help me in any way please write, also suggest some ideas about using recursion/DP for solving this problem. Thanks.

  • Subsonic - How to use SQL Schema / Owner name as part of the namespace?

    - by CResults
    Hi there, I've just started using Subsonic 2.2 and so far very impressed - think it'll save me some serious coding time. Before I dive into using it full time though there is something bugging me that I'd like to sort out. In my current database (a SQL2008 db) I have split the tables, views, sps etc. up into separate chunks by schema/owner name, so all the customer tables are in the customer. schema, products in the product. schema etc., so a to select from the customers address table i'd do a select * from customer.address Unfortunately, Subsonic ignores the schema/owner name and just gives me the base table name. This is fine as I've no duplicates between schemas (e.g Customer.Address and Supplier.Address don't both exist) but I just feel the code could be clearer if I could split by schema. Ideally I'd like to be able to alter the namespace by schema/owner - I think this would have least impact on SubSonic yet make the resulting code easier to read. Problem is, I've crawled all over the Subsonic source and don't have a clue how to do this (doesn't help that I code in VB not C# = yes I know, blame the ZX Spectrum!!) If anyone has tackled this before or has an idea on how to solve it, I'd be really grateful, Thanks in advance. Ed

  • UIScrollView notifications

    - by ryyst
    Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

  • How does one properly redefine self while avoiding the "Multiple methods named ..." warning?

    - by Elise van Looij
    In Apple's The Objective-C Programming Language: Defining a Class the section named "Redifining self" recommends that that class methods allocate and return instances use 'self' only to allocate an instance and then refer only to that instance. Thus, I have a number of subclasses, that have class methods along the lines of: + (id)scrollViewWithFrame: (NSRect)rectFrame { id newInstance = [[[self alloc] initWithFrame:rectFrame] autorelease]; [newInstance setHasHorizontalScroller: YES]; [newInstance setHasVerticalScroller: YES]; [newInstance setBorderType: NSNoBorder]; [newInstance setAutoresizingMask: (NSViewWidthSizable | NSViewHeightSizable)]; return newInstance; } The above is, of course, a subclass of NSScrollView. Unfortunately, Xcode 3.x all these NSView subclasses now raise warnings: "Warning: Multiple methods named '-setAutoresizingMask' found". I believe it has something to do with GCC 4.2, the settings of which I have not changed. The warning is correct, of course, since NSView and its various subclasses all implement setAutoresizingMask, but it is also unnecessary. Since they're only warnings, I ignore them but there is a risk that in between the thirty or so unnecessary ones, a really useful warning lurks which I simply don't see. So, what to do? I do want to adhere to good coding practices and I want to build warning-free apps -- how can I do both?

  • Delphi - OnKeyPress occurs before TStringGrid updates cell with new character

    - by JMTyler
    Coding in Delphi, attaching an OnKeyPress event handler to a TStringGrid: The OnKeyPress event fires before the grid cell that the user is typing into has actually updated its value with the key that has been pressed. This is obviously a problem, when I want to know what the contents of that cell are at this moment, as in, as the user modifies it. The "hacked" solution is simple, if you're not considering every detail: just grab the value from the cell and, since the OnKeyPress event comes along with a Key parameter, append that value to the end - now you have the current value of the cell! False. What if the user has selected all the text in the cell (ie: "foo") and they are now typing 'b'. Since they selected the text, it will be erased and replaced with the letter 'b'. However, the value of the cell will still display as "foo" in OnKeyPress, and the value of Key will be 'b', so the above logic would lead the application to conclude that the cell now contains "foob", which we know is not true. So. Does anybody know how to get around this problem? Is there a way to make OnKeyPress react after the grid's contents have been updated, or perhaps a way to force an update at the start of the handler? I am desperately avoiding the use of the OnKeyUp event here, so any suggestions aside from that would be greatly appreciated.

  • Binding ListBox to List (Collection) in XAML

    - by david2tm
    Hello, I'm learning WPF, so I'm kind of n00b in this. I saw some examples about how to do what I want to do, but nothing exactly... The question: I want to bind List to ListBox. I want to do it in XAML, w/o coding in code behind. How can I achieve that? Right now I do it that way: <!-- XAML --> <ListBox x:Name="FileList"> <ListBox.ItemTemplate> <DataTemplate> <Label Content="{Binding Path=.}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> // Code behind public MainWindow() { // ... files = new List<string>(); FileList.ItemsSource = files; } private void FolderBrowser_TextChanged(object sender, RoutedEventArgs e) { string folder = FolderBrowser.Text; files.Clear(); files.AddRange(Directory.GetFiles(folder, "*.txt", SearchOption.AllDirectories)); FileList.Items.Refresh(); } But I want to get rid of FileList.ItemsSource = files; and FileList.Items.Refresh(); in C# code. Thanks

  • rails + compass: advantages vs using haml + blueprint directly

    - by egarcia
    I've got some experience using haml (+sass) on rails projects. I recently started using them with blueprintcss - the only thing I did was transform blueprint.css into a sass file, and started coding from there. I even have a rails generator that includes all this by default. It seems that Compass does what I do, and other things. I'm trying to understand what those other things are - but the documentation/tutorials weren't very clear. These are my conclusions: Compass comes with built-in sass mixins that implement common CSS idioms, such as links with icons or horizontal lists. My solution doesn't provide anything like that. (1 point for Compass). Compass has several command-line options: you can create a rails project, but you can also "install" it on an existing rails project. A rails generator could be personalized to do the same thing, I guess. (Tie). Compass has two modes of working with blueprint: "basic" and "semantic" usage. I'm not clear about the differences between those. With my rails generator I only have one mode, but it seems enough. (Tie) Apparently, Compass is prepared to use other frameworks, besides blueprint (e.g. YUI). I could not find much documentation about this, and I'm not interested on it anyway - blueprint is ok for me (Tie). Compass' learning curve seems a bit stiff and the documentation seems sparse. Learning could be a bit difficult. On the other hand, I know the ins and outs of my own system and can use it right away. (1 point for my system). With this analysis, I'm hesitant to give Compass a try. Is my analysis correct? Are Am I missing any key points, or have I evaluated any of these points wrongly?

  • Django - Override admin site's login form

    - by TrojanCentaur
    I'm currently trying to override the default form used in Django 1.4 when logging in to the admin site (my site uses an additional 'token' field required for users who opt in to Two Factor Authentication, and is mandatory for site staff). Django's default form does not support what I need. Currently, I've got a file in my templates/ directory called templates/admin/login.html, which seems to be correctly overriding the template used with the one I use throughout the rest of my site. The contents of the file are simply as below: # admin/login.html: {% extends "login.html" %} The actual login form is as below: # login.html: {% load url from future %}<!DOCTYPE html> <html> <head> <title>Please log in</title> </head> <body> <div id="loginform"> <form method="post" action="{% url 'id.views.auth' %}"> {% csrf_token %} <input type="hidden" name="next" value="{{ next }}" /> {{ form.username.label_tag }}<br/> {{ form.username }}<br/> {{ form.password.label_tag }}<br/> {{ form.password }}<br/> {{ form.token.label_tag }}<br/> {{ form.token }}<br/> <input type="submit" value="Log In" /> </form> </div> </body> </html> My issue is that the form provided works perfectly fine when accessed using my normal login URLs because I supply my own AuthenticationForm as the form to display, but through the Django Admin login route, Django likes to supply it's own form to this template and thus only the username and password fields render. Is there any way I can make this work, or is this something I am just better off 'hard coding' the HTML fields into the form for?

  • Defining a variable in a class and using it in functions

    - by Josh
    I am trying to learn PHP classes so I can begin coding more OOP projects. To help me learn I am building a class that uses the Rapidshare API. Here's my class: <?php class RS { public $baseUrl = 'http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub='; function apiCall($params) { echo $baseUrl; } } ?> $params will contain a set of key pair values, like this: $params = array( 'sub' => 'listfiles_v1', 'type' => 'prem', 'login' => '746625', 'password' => 'not_my_real_pass', 'realfolder' => '0', 'fields' => 'filename,downloads,size', ); Which will later be appended to $baseUrl to make the final request URL, but I can't get $baseUrl to appear in my apiCall() method. I have tried the following: var $baseUrl = 'http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub='; $baseUrl = 'http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub='; private $baseUrl = 'http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub='; And even tried $this->baseUrl = $baseUrl; in my apiCall() methid, I don't know what the hell I was thinking there though lol. Any help is appreciated thanks :)
