  • Preserving multi-byte characters in Flex XML object

    - by Dan Petker
    I'm having an issue with the Flex XML object type mangling multi-byte characters (such as Japanese or Chinese characters). The basic setup is this. I'm getting an XML-formatted string from the server, and in that string there can be multi-byte characters. A lot of the time, these characters are in attributes, for example: <example id="foo" name="[some multi-byte characters]"/> Now, when I examine the raw string, the multi-byte characters display just fine. However, as soon as I convert the string to an XML object using the top-level XML() function, all the multi-byte characters become mangled. I've tried setting the XML's encoding by including an <?xml version="1.0" encoding="utf-8"?> element in the XML-formatted string, but this doesn't seem to have any effect on the resulting XML object. Is there a way to get the XML object to respect the encoding of the XML-formatted string and prevent the multi-byte characters from being mangled?

  • ^M characters when using Tramp (on Windows) to connect to Ubuntu Server

    - by jamting
    I've set up Tramp on Emacs on my Windows 7 box (64 bit). For this test, this is the only thing in my emacs-config: (setq tramp-default-method "plink") Then I connect to my Ubuntu Server 9.10 running in a VM on my local network. Connection goes fine, i can use dired to browse folders and open files. Yay! However, git status shows up as: Git:master^M An when i open speedbar all folders and files ends with ^M, ie: <+ conf/^M Does anyone know how to prevent this line-ending collision from occurring?

  • How do I allow inline images with data urls on .NET 4 without triggering request validation?

    - by Johan Driessen
    I'm using the jQuery jstree plugin (http://jstree.com) in a ASP.NET MVC 2 project on .NET 4 RC. It comes with some stylesheets with inline images with data urls, like this: .tree-checkbox ul { background-image:url(data:image/gif;base64,R0lGODlhAgACAIAAAB4dGf///yH5BAEAAAEALAAAAAACAAIAAAICRF4AOw==); } Now, the url for the background image contains a colon, which .NET 4 thinks is an unsafe character, so I get this error message: A potentially dangerous Request.Path value was detected from the client (:). According to the documentation, I am supposed to be able to prevent this by adding <pages validateRequest="false" /> to my Web.config, but that doesn't seem to help. I have tried adding it to the main Web.config for the application, as well as to a special Web.config in the /config folder, but to no avail. Is there any way to get .NET to allow this?

  • Visual Studio 2008/2010 & SQL Server 2008 on Windows 7 Home Premium

    - by Steve
    Are there any limitations with respect to developing ASP.NET and WPF apps using VS 2008/2010 and SQL Server 2008 on Windows 7 Home Premium? I know you can run IIS 7.5 on Home Premium. I Googled and Binged on Home Premium and VS/SQL Server and couldn't find much. It doesn't look like the features missing from Home Premium, domain joining, xp mode, etc... shouldn't prevent one from running and developing in VS/SQL Server. Update I did discover one limitation w/IIS 7.5 and it applies to all versions of Windows 7 I think. You can't create your own self signed SSL certificate specifying a name other than the machine name. You're stuck with your machine name which isn't that big a deal, but it is a change from previous versions.

  • Hashes vs Numeric id's

    - by Karan Bhangui
    When creating a web application that some how displays the display of a unique identifier for a recurring entity (videos on YouTube, or book section on a site like mine), would it be better to use a uniform length identifier like a hash or the unique key of the item in the database (1, 2, 3, etc). Besides revealing a little, what I think is immaterial, information about the internals of your app, why would using a hash be better than just using the unique id? In short: Which is better to use as a publicly displayed unique identifier - a hash value, or a unique key from the database? Edit: I'm opening up this question again because Dmitriy brought up the good point of not tying down the naming to db specific property. Will this sort of tie down prevent me from optimizing/normalizing the database in the future? The platform uses php/python with ISAM /w MySQL.

  • .NET Regular Expression to split multiple words or phrases

    - by Cj Anderson
    I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring? Private m_Reg As Regex m_Reg = New Regex("([^""^\s]+)\s*|""([^""]+)""\s*") Dim rezsplit = m_Reg.Split(criteria)

  • Display a "Waiting Menssage" before the POST form send

    - by DomingoSL
    I have a upload file form, when you hit Submit it send the file to my server, but it takes a while, in the mean time i need to tell the user wait in order to get the file uploaded, because he can press Submit again because there is no menssage to prevent him. So, the user fill a few fields in the form, including a file. When he Send the form it sends the variables via POST to the same page: <form action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data" method="post"> A php script detect the page now have POST variables a do something. In the time between the send action and the page reload i need to display a mensage, how can i do that??? Thanks It will be nice if you now how to trigger that with colorbox. I know how to use it from a link but no from this POST action.

  • Flash receives mouse events under an HTML element when opacity set

    - by Török Gábor
    I have an HTML document with a Flash object and an absolutely positioned HTML element above it. If I set the HTML element's opacity CSS property to any value less than 1, the Flash object (that is actually covered) receives mouse events. This problem cannot be reproduced with pure HTML elements. Furthermore, Flash only receives hover events, so I cannot click below the layer. I put a demonstration of the problem online. I get this behavior in Firefox 3.6, Safari 4.0 and Chrome 5.0 in both Mac and Windows. Flash plugin version 10 is installed. Is it a bug or the the normal and expected behavior? If the latter, then how can I prevent Flash receiving events when it is covered with a translucent layer?

  • How can I detect client-side when a page load is the result of an AJAX history point?

    - by Nick
    I'm trying to prevent a "flicker" effect that is occurring on my ASP.NET page which occurs when a user navigates to the page via the browser back button after having navigated away from it. The reason for the flicker is that I'm using an Update Panel which has some content in there on the initial page-load. As a result, when the page is loaded via a back button that initial content is shown very briefly before it is updated with the correct History-aware data. In order to overcome this I am intending on having the updatepanel hidden (display: none) on inital page load and then show it as long as we don't have any history to deal with. The problem is that I can't find out what to check to determine if there's any history. I can see that the Sys.Application has a _history member but when I'm checking it on page init it is null each time. Does anyone know what I should be checking to determine if there's history to deal with for a page load client-side? And at what point to do it?

  • Objective-C initial values of created C-array

    - by kpower
    I create an array, similar to classic C (not NSArray or one of it's children) - something like BOOL i[5];. And I want to make all its values to be equal to NO. First of all, I didn't found any information about initial values of such arrays (I know that in classic C they will be undefined, but don't know exactly about Objective-C. I found info about classes and its inner data [after allocation, without initialization], but not about simple data types). And the second, if I should set array values manually - should I use memset(...); or something different? To prevent possible questions... I want to use this construction as array of temporary boolean flags and don't think that it is proved to use something like NSArray here.

  • Ensuring unique ID attribute for elements within ScriptControl

    - by Andy West
    I'm creating a control based on ScriptControl, and I'm overriding the Render method like this: protected override void Render(HtmlTextWriter writer) { RenderBeginTag(writer); writer.RenderBeginTag(HtmlTextWriterTag.Div); writer.Write("This is a test."); writer.RenderEndTag(); RenderEndTag(writer); } My question is, what if I want to assign the div an ID attribute and have it be unique on the page, even if there are mulitple instances of my control? I've seen other people's code that does this: writer.AddAttribute(HtmlTextWriterAttribute.Id, this.ID + "_divTest"); That will prevent naming conflicts between instances of my control, but what if I've already created a div elsewhere on the page that coincidentally has the same ID? I've also heard about implementing INamingContainer. Would that apply here? How could I use it?

  • Firing trigger for bulk insert

    - by Deepa
    ALTER TRIGGER [dbo].[TR_O_SALESMAN_INS] ON [dbo].[O_SALESMAN] AFTER INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for trigger here DECLARE @SLSMAN_CD NVARCHAR(20) DECLARE @SLSMAN_NAME NVARCHAR(20) SELECT @SLSMAN_CD = SLSMAN_CD,@SLSMAN_NAME=SLSMAN_NAME FROM INSERTED IF NOT EXISTS(SELECT * FROM O_SALESMAN_USER WHERE SLSMAN_CD = @SLSMAN_CD) BEGIN INSERT INTO O_SALESMAN_USER(SLSMAN_CD, PASSWORD, USER_CD) VALUES(@SLSMAN_CD, @SLSMAN_CD,@SLSMAN_NAME ) END END This is the trigger written for a table(O_SALESMAN) to fetch few columns from it and insert it into one another table(O_SALESMAN_USER). Presently bulk data is getting inserted into O_SALESMAN table through a stored procedure, where as the trigger is getting fired only once and O_SALESMAN_USER is having only one record inserted each time whenever the stored procedure is being executed,i want trigger to run after each and every record that gets inserted into O_SALESMAN such that both tables should have same count which is not happening..so please let me know what can be modified in this Trigger to achieve the same....

  • Mysql out of disk space

    - by Paddy
    I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

  • How should I go about creating a point system for users like SO and yahoo answers?(PHP)

    - by ggfan
    I am creating a voting system for a Q&A site project in which if a user asks a question, he/she losses -5 points; answer a question +5, vote a question +1, etc. (kind of like SO and yahoo answers) --To create the basic arithmetic, I have a "users_points" table that relates the user_id and their total points. +---+---------+ | 1 | 100 | +---+---------+ | 2 | 54 | +---+---------+ --Basically if the users does certain task, it would + or - the points. How do I prevent users from say voting an answer up 100 times. ex: I want a user to be only able to vote once per question, etc.

  • UISearchbar clearButton forces the keyboard to appear

    - by DASKAjA
    I have a UISearchBar which acts as a live filter for a table view. When the keyboard is dismissed via endEditing:, the query text and the gray circular "clear" button remain. From here, if I tap the gray "clear" button the keyboard reappears as the text is cleared. How do I prevent this? If the keyboard is not currently open I want that button to clear the text without reopening the keyboard. There is a protocol method that gets called when I tap the clear button. But sending the UISearchBar a resignFirstResponder message doesn't have any effect on the keyboard.

  • Choose a local file w/o uploading the chosen file

    - by Austin Hyde
    I am making a simple development tool for myself using PHP on my local development server. I would like a way to have a simple file-chooser to select a file without uploading it, but just retaining the file path. This is useful, because I will be the only one using the tool, and so PHP will have access to the chosen file without having it uploaded. My first thought is to have a <input type="file"...>, but as far as I know, there's no way to prevent the upload from happening. Is there a way to do this?

  • My OpenGL game switches Aero DWM Glass off.

    - by marc40000
    Hi ! I wrote a free game a few years ago: http://www.walkover.org. For the lobby and menus, it uses normal dialogs like win32. When the actual game starts it uses OpenGL. Now, on Windows 7, when the actual game starts, it switches windows aero glass off and switches it back on when the game is over. Is there something I can do to prevent this from happening? Some special flags that keep the glass on if it is on? (For newer, I have been using DirectX and this doesn#t happen there.) Maybe some (new) flag I have to specify somewhere? Thx Marc

  • Cross Domain Scripting Issues & JSONP

    - by DaveDev
    Our Client requires that we supply Widgits for their site. They want to link to us to get Html & the jQuery required to manipulate the Html and do asynchronous requests. I understand that there are cross-domain security limitations that would prevent this from being a possibility, but that some of those limitations are aleviated by using JSONP as the data transfer format. I'm finding it difficult in finding an explanation of what's possible in the context of what I'm trying to achieve. Could somebody please fill me in?

  • Parsing a XML File and Replacing Chosen Node With Values From Text File

    - by transmogrify
    I wrote a C# Winforms program to take a XML file and load values from a text file into each occurrence of that field which the user specifies on the UI. For whatever reason, the program inserts a carriage return on any nodes which don't contain a value. For example, it will do that to <example></example> whereas it will not misbehave on something like <country>USA</country> What is causing it to do this and how can I prevent it? Here is the code from the part which handles this functionality. XmlDocument LoadXmlDoc = new XmlDocument(); StreamReader sr = File.OpenText(DataLoadTxtBx.Text); string InputFromTxtFile; LoadXmlDoc.Load(XmlPath.Text); XmlNodeList NodeToCreateOrReplace = LoadXmlDoc.GetElementsByTagName(XmlTagNameTxtBx.Text); foreach (XmlNode SelectedNode in NodeToCreateOrReplace) { if ((InputFromTxtFile = sr.ReadLine()) != null) { SelectedNode.InnerText = InputFromTxtFile; } } sr.Close(); LoadXmlDoc.Save(XmlPath.Text);

  • How can I stop sorl thumbnail from breaking with very long filenames?

    - by bitbutter
    I've noticed that when working with SORL thumbnail, sometimes a user will upload an image with a very long filename, longer than the varfield in the database can hold. The name gets truncated in the database and the project gives errors whenever the image is requested. Is there a smart and safe way to have django automatically truncate long filenames in sorl uploads (prior to saving them in the database) to prevent this sort of thing? As reference, here's how the relevant model from my current project looks: class ArtistImage(models.Model): artist = models.ForeignKey(Artist) position = models.IntegerField() image = ThumbnailField( thumbnail_tag='<span class="artistimagewrapper"><img class="artistimage" src="%(src)s" width="%(width)s" height="%(height)s"></span>', upload_to='uploaded_images/artistimages', size=(900,900), quality=100, options={'crop': 'center'}, extra_thumbnails={ 'small':{ 'size':(92,92), 'quality':100, 'options':{'crop': 'center'}, } } ) class Meta: ordering = ('image',) def __unicode__(self): return (u"%s" % self.image)

  • jQuery event.stopPropagation is not working on <a>

    - by HorusKol
    I have the following javascript: $('#ge-display').click(function (event) { window.open('/googleearth/ge-display.php','','scrollbars=yes,menubar=no,height=650,width=1000,resizable=yes,toolbar=yes,location=no,status=no'); event.stopPropagation(); return false; }); the element with id 'ge-display' is a standard link: <a href="/googleearth/ge-display.php" id="ge-display" target="_blank">Load Google Earth Plugin (in a new window)</a> The problem is - when I take out the 'return false;' line from the click event handler, the javascript popup opens, and then another browser window opens - I thought stopPropagation() would prevent the links own click handler? I've also tried stopImmediatePropagation() - but I still need to return false to stop the default behaviour of the link.

  • Session Variable Not Being Saved When Using Wizard Control ASP.NET

    - by davemackey
    I have a wizard control. When someone clicks a button within the wizard control I automatically advance to the next step (rather than forcing them to click next). However, this seems to cause the session state variable not to be saved. I've done some research and noticed that Response.Redirect does hard redirects that truncate page execution - and that you can add a false parameter to prevent this...what I'm wondering is if the wizard control is doing the same thing and if so, if I can add a parameter to this as well? Dave.

  • Is it normal that conversationId keeps increasing after each page request?

    - by Casper
    Hi I'm building a Seam application and have a question: I got a stateless session bean (default seam scope) with a delete and a select method. A page which contains a datamodel loads and got links to select and delete each row (both links refer to the actionmethods in the bean). The delete method deletes the selected row from the list and returns null (reloads page). The select method loads a new page where the selected row can be edited. Each time a link in the datamodel is clicked and an action gets fired, the conversationId gets increased. Is this normal behaviour since im not even in a conversation? If it ain't normal behaviour, what's best practice to prevent this from happening?

  • Using transactions with ADO.NET Data Adapters.

    - by Ergwun
    Scenario: I want to let multiple (2 to 20, probably) server applications use a single database using ADO.NET. I want individual applications to be able to take ownership of sets of records in the database, hold them in memory (for speed) in DataSets, respond to client requests on the data, perform updates, and prevent other applications from updating those records until ownership has been relinquished. I'm new to ADO.NET, but it seems like this should be possible using transactions with Data Adapters (ADO.NET disconnected layer). Question part 1: Is that the right way to try and do this? Question part 2: If that is the right way, can anyone point me at any tutorials or examples of this kind of approach (in C#)? Question part 3: If I want to be able to take ownership of individual records and release them independently, am I going to need a separate transaction for each record, and by extension a separate DataAdapter and DataSet to hold each record, or is there a better way to do that? Each application will likely hold ownership of thousands of records simultaneously.

  • Core Data Image Won't Load Into NSTableView Image Cell

    - by jcady
    In my code I am storing an image into my Core Data model (works fine). If I set up my view to have an NSImageView and bind its Data to Controller Key: selection and modelKeyPath: myImagePath, it works. It will show each image for the selected row. I then create a new column in my NSTableView and drag an image cell onto the column. However, I cannot get my Core Data bindings to have the image show up in the cell. I have tried binding both value and data, but no luck. Since I am sure the image is stored properly, what am I doing wrong in my binding to prevent the image from showing up in the table cell? Thanks so much. (My background: new Cocoa developer who has recently gone through the entire Hillegass book.)
