  • Flex RGBA colors in CSS

    - by jscheel
    Hello all, I am trying to style a DataGrid component so that the background is transparent (Flex 4). Rgba colors work fine if I make "alternatingItemColors" an attribute on the component, but if I try to declare it in my css stylesheet, I cannot declare the alpha value. Works (mxml): <mx:DataGrid id="songGrid" width="800" height="529" dataProvider="{songs}" itemClick="handleRowClick(event);" x="145" y="168" headerStyleName="dataGridHeader" alternatingItemColors="[0xFFFFFFFF, 0xFFFFFFFF]"> Doesn't Work (css): mx|DataGrid { alternatingItemColors: #FFFFFFFF, #FFFFFFFF; } If I enter the values as "0xFFFFFFFF", I get a parse error, because it's not proper css (of course, most of flex's css isn't proper css, but I digress...). So, is there any way to declare the alpha value of these colors in the css?

  • Tag filtering Query using T-SQL and Linq-to-SQL?

    - by EdenMachine
    I'm trying to figure out how to allow a user to enter in a string of tags (keywords separated by spaces) in a textbox to filter a grid of results. Here are the tables: PACKETS *PacketID Name PACKETTAGS *PacketTagID PacketID TagID Tags *TagID Name Here is the basic query without the WHERE parameters: SELECT Packets.Name, Tags.Name AS Tag, PacketTags.PacketTagID FROM Packets INNER JOIN PacketTags ON Packets.PacketID = PacketTags.PacketID INNER JOIN Tags ON PacketTags.TagID = Tags.TagID I need to filter out all the Packets that don't have tags that match any of the words BUT ALSO ONLY include the Packets that have the tags entered in the string of text (spaces separate the tags when entered into the textbox) I'm starting with the basics by figuring this out in t-SQL first but ultimately I need to be able to do this in Linq-to-SQL

  • VB.NET Inputbox - How to identify when the Cancel Button is pressed?

    - by The Sasquatch
    I have a simple windows application that pops up an input box for users to enter in a date to do searches. How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world. Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.

  • ASP.NET GridView - how to enable validation declaratively

    - by Joe
    It it possible to enable validation in an ASP.NET GridView purely declaratively? What I've tried: A GridView bound to an ObjectDataSource with SelectMethod and UpdateMethod defined The GridView contains some ReadOnly BoundField columns and a TemplateField whose EditTemplate contains a TextBox and a RegularExpressionValidator that only allows numeric input in the TextBox. The GridView also contains a CommandField with ShowEditButton=true and CausesValidation=true. If I click on Edit, enter an invalid value, then click on Save, there is a PostBack, and an exception is thrown in the server (Input string was not in a correct format). I can of course avoid this by adding validation code to the RowUpdating event handler on the server (see below), but is there any declarative way to force the validation to be done without adding this code? protected void MyGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) { Page.Validate("MyValidationGroup"); if (!Page.IsValid) { e.Cancel = true; } }

  • Getting MAX_INT from NSDateComponents

    - by MattyW
    I'm trying to write my first iPhone app, and I'm using a date picker object for the user to enter their date of birth. Part of my app requires the year in int format. I've added the code as below. What's odd is that 'month' gets the right value. But day and year seem to be stuck at MAX_INT (2147483647). Can anyone tell me what I'm doing wrong? -(IBAction)dateOfBirthChanged:(id)sender { NSCalendar* calender = [NSCalendar currentCalendar]; NSDateComponents* dateComponents = [calender components:NSMonthCalendarUnit fromDate:[datepicker date]]; NSInteger day = [dateComponents day]; NSInteger month = [dateComponents month]; NSInteger year = [dateComponents year]; label.text = [NSString stringWithFormat:@"Your year of birth is %d", year]; }

  • Do encryption algorithms provide really unique results?

    - by Mikulas Dite
    I was wondering whether md5, sha1 and anothers return unique values. For example, sha1() for test returns a94a8fe5ccb19ba61c4c0873d391e987982fbbd3, which is 40 characters long. So, sha1 for strings larger than 40 chars must be the same (of course it's scrambled, because the given input may contain whitespaces and special chars etc.). Due to this, when we are storing users' passwords, they can enter either their original password or some super-long one, which nobody knows. Is this right, or do these hash algorithms provide really unique results - I'm quite sure it's hardly possible.

  • Submit form if ajax validator returns true using jquery

    - by Anthony
    I am not sure where I'm going wrong. The idea is that before the form is submitted, one of the input fields is sent to a server-side validator via ajax. If the response is 1, the input is valid and the form should be submitted. If the response is 0, the form should not be submitted. The issue is that I can't figure out how to set a variable within the ajax request function that will prevent the form from being submitted. This is what I have: $("#form").submit(function() { var valid= false; var input = $("#input").val(); $.ajax({ type: "POST", url: "validator.php", data: "input=" + input, success: function(msg){ valid = (msg == 1) ? true : false; if(!valid) { $("#valid_input").html("Please enter valid info"); } else { $("#valid_input").html(""); } } }); return valid; });

  • PHP cors validation

    - by Brian Putt
    I have an endpoint that takes GET requests to collect data from any source that wants to send data. Is there a way to run some validation that the data is in fact coming from the sources we allowed? They enter the website url that they will be sending the data from and we generate an api key. The data is sent via a javascript file that they install onto their website. I have the Access-Control-Allow-Origin set to * as it doesn't necessarily scale to add in hundreds or more websites to that header and that in itself is a security risk as it shows anyone who wants to look at the headers who uses the script. Currently I am thinking of using the http_origin / origin referrer, but obviously that doesn't do too much

  • C++ open() fails for no apparant reason

    - by jondoe
    The following code: char filename[64]; ifstream input; cout << "Please enter the filename: " << endl; cin >> filename; input.open(filename); if (!input.is_open()) { cout << "Opening file " << filename << " failed." << endl; exit(1); } fails, it enters the if() and exits. What could possibly be the cause for this? I'm using Microsoft Visual C++. When I hardcoded the filename as a constant it instead ended up garbled: http://pici.se/pictures/CNQEnwhgo.png Suggestions?

  • mysql PHP query question

    - by camran
    Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

  • How save JavaScript and HTML in option without it being auto-escaped?

    - by bobsoap
    And there I thought I knew Wordpress well. It now seems that update_option() auto-escapes code. If I want to save some Javascript or HTML code in an option, this behavior renders the code unusable. I refuse to do a str_replace on the returned value to filter out every backslash. There has to be a better way. Here's the PHP for the text box to enter some code: $option = unserialize(get_option('option')); <textarea name="option[box]"><?php echo $option['box']; ?></textarea> This is what happens after submitting the form (in essence): update_option('option', serialize($_POST)); Any ideas?

  • CMD Execption Handling C/C++

    - by ciyo
    I will use some CMD commands in my program and these commands might throw some exceptions. And as you know, when an exception accours, CMD writes its own error message the screen. But, I want to write my own error message. My question is this: Is there a way to block CMD messages and write only my own error messages? P.S. This is not a complex program. It executes CMD commands using System(). Example: Let's say, the user can rename and copy any files in the program. As you know, if the user does not enter file's path properly, an error message is showed on the screen. And I want that this error message never appears on the screen. Only my own error message is showed. Thank you!

  • Why doesn't Google OpenID provider work with PHP-OpenId on my server?

    - by Steven Devijver
    Hey, I'm using PHP-OpenId 2.1.3 which I've unzipped on my server here (this is the consumer example that comes with PHP-OpenId). When I enter the Google OpenId url (https://www.google.com/accounts/o8/id) and submit I get a blank screen. When I try the exact same example code on the PHP-OpenId website here with the same URL it works fine. I don't understand what I'm doing wrong. The only thing I can think of is that somehow Google does not want to work with my server. Any ideas how to make this work? Thanks

  • How to, set-justification-full per line in emacs without messing up on return?

    - by inaki
    Hi, I have two problems in emacs. First. How do I set-justification-full for the whole document? I can do M-X set-justification-full for a region successfully, but I would like to make it work in the whole document. Second. How do I manage not to get lines jumping from one place to another when I have done set-justification-full, and press enter? That is, say I have the following paragraph: %%if normalized beforehand then the rule would be, %%\begin{gather} %%(\hat{y}_{i}^{'} \times \hat{y}_{i+1}^{'}) \cdot \hat{z}_{mst} = 1, \quad then \ \Omega 1\\ %%(\hat{y}_{i}^{'} \times \hat{y}_{i+1}^{'}) \cdot \hat{z}_{mst} = %%-1,\quad then \ \Omega When I do set-justification-full, it will convert six lines into three lines, that is, what I want to do is a per line justification. Is this possible in emacs? Thank you all very much for your help. Inhaki2006

  • Django 1.2: Dates in admin forms don't work with Locales (I10N=True)

    - by equalium
    I have an application in Django 1.2. Language is selectable (I18N and Locale = True) When I select the english lang. in the site, the admin works OK. But when I change to any other language this is what happens with date inputs (spanish example): Correctly, the input accepts the spanish format %d/%m/%Y (Even selecting from the calendar, the date inserts as expected). But when I save the form and load it again, the date shows in the english form: %Y-%m-%d The real problem is that when I load the form to change any other text field and try to save it I get an error telling me to enter a valid date, so I have to write all dates again or change the language in the site to use the admin. I haven't specified anything for DATE_INPUT_FORMATS in settings nor have I overridden forms or models. Surely I am missing something but I can't find it. Can anybody give me a hint?

  • Regex whitespace and special characters

    - by Sam R.
    I have this regular expression: [^\\s\"']+|\"([^\"]*)\"|'([^']*)' which works for splitting a string by white spaces, and anything within a quotation is not delimited. However, I notice that if I put in a string that starts with "" no matches are found. How would I correct this? For example, if I enter " test 2". I want it to match to [, test, 2] Note: using java to compile the regex, here is some code Pattern pattern = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher matcher = pattern.matcher(SomeString); while (matcher.find()){ String temp = matcher.group(); //... Do something ... } Thanks.

  • Flex Application for PlayBook Text Input Variable

    - by user568128
    I know this is probably a very simple question, but can someone please walk me through how to take what a user inputs into a s:TextInput and use that as a variable in a JSON data request? Basically, I want to have a user enter a search term, like "math" and then have that placed into a variable so I can use it in a JSON request. Something like public var q:String, except that my search box (and hence user input) is on another "view" of the application. I've just started with Flex Mobile applications and I might be way out of my league. Does anyone know how to do this?

  • Easiest way to submit data via PHP?

    - by Abijah
    I'm new to PHP, and have spent 10 hours trying to figure this problem out. The goal is to take all data entered into this order form, and send it to my email via PHP. I have 2 questions: 1. I can get PHP to send data from a single menu item (example: Mexican Tortas), but how do I get PHP to send data from multiple items (example: Mexican Tortas, Fish Sandwich and Hamburger)? 2. How do I tell PHP to not send data from menu items that don't have the "How Many?" or "Customize It?" text fields filled out? If you could provide a super simple example (or a link to a learning resource) I would really appreciate it. Thank you, Abijah PHP <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "New Order"; $name_field = $_POST['name']; $phone_field = $_POST['phone']; $item = $_POST['item']; $quantity = $_POST['quantity']; $customize = $_POST['customize']; } $body = "Name: $name_field\nPhone: $phone_field\n\nItem: $item\nQuantity: $quantity\nCustomize: $customize"; echo "Data has been submitted to $to!"; mail($to, $subject, $body); ?> HTML <form action="neworder.php" method="POST"> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/mexicantortas.jpg"> <h1>Mexican Torta - $8.50</h1> <input name="item" type="hidden" value="Mexican Torta"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/fishsandwich.jpg"> <h1>Fish Sandwich - $8.50</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/hamburgers.jpg"> <h1>Hamburger w/ Fries - $7.00</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class="horizontal_form"> <div class="form"> <h2>Place Your Order Now: <font size="3"><font color="#037B41">Fill in the form below, and we'll call you when your food is ready to be picked up...</font></font></h2> <p class="name"> <input type="text" name="name" id="name" style="text-align:center;" onClick="this.value='';" value="Enter your name"/> </p> <p class="phone"> <input type="text" name="phone" id="phone" style="text-align:center;" onClick="this.value='';" value="Enter your phone #"/> </p> <p class="submit"> <input type="submit" value="Place Order" name="submit"/> </p> </div><!-- FORM --> </div><!-- HORIZONTAL_FORM --> </form>
