• Problem with ajax and posting non-latin characters

  - by jason

  Posting non-latin based languages with ajax + jquery doesn't save to mysql the correct text. What I have done is this: I am getting multiple translated words from Google's translation api. The ajax request is showing the correct translations for all languages. But when i try and insert this into the db it shows up in php my admin as garbled text I added AddDefaultCharset UTF-8 to .htaccess file on the root. I tried setting the header in php to utf-8 and this did not work. I have tried adding a contentType to ajax setup but this didn't work also. Any suggestions appreciated. jason

• Pull down UIToolbar above UIWebView inside UIScrollView

  - by Nick VanderPyle

  I'd like to display a toolbar above a UIWebView but hide the toolbar until the person "pulls it down". The same functionality can be seen in Safari on the iPhone. When the page loads, the toolbar containing the address is hidden. You must pull it down. In Safari it's possible to scroll up and eventually see the toolbar or scroll down through the page contents. I've tried placing a UIToolbar and UIWebView inside a UIScrollView but it didn't work. I've tried setting the UIScrollView to the size of the toolbar and webview combined, but that didn't work. - (void)viewDidLoad{ CGSize size = CGSizeMake(webView.frame.size.width, toolBar.frame.size.height + webView.frame.size.height); [scrollView setContentSize:size]; } How should I go about doing this?

• Why addming permissions to an existing AppDomain has no effect?

  - by MainMa

  Hi, I have a following code which behaves strangely in .NET 4.0: // AppDomain is created, and permissions which were added to `sandboxPermissions` are added successfully. sandboxAppDomain = AppDomain.CreateDomain("SandboxDomain", null, appDomainSetup, sandboxPermissions, new[] { commonStrongName }); // Trying to add a new permission to an AppDomain which is already created. sandboxAppDomain.PermissionSet.AddPermission(new FileIOPermission(FileIOPermissionAccess.AllAccess, @"C:\Some\Path\Here")); // Setting breakpoint to this line: `permissions` contains every permission which was added to `sandboxPermissions`, but no trace of C:\Some\Path\Here related permission. var permissions = sandboxAppDomain.PermissionSet.ToXml(); Every permission added before creating an AppDomain is just here, as expected. But adding permissions after an AppDomain is created has no effect at all. There are no exceptions thrown (nor first-chance ones). What can it be? If the framework method (AddPermission) fails to do what it was expected to do, mustn't it throw an exception?

• Error calling webservice from JQuery

  - by Robban

  I have a strange problem when I'm trying to call a simple webservice method from Jquery. Locally it works fine, but on my test-server it does not. The jquery request looks like this (only showing the actual request and not the rest of the method): $.ajax({ type: "POST", url: "/Service/Service.asmx/AddTab", data: "tab=" + element.innerHTML, success: function(msg) { alert('success'); } }); When I run this locally from the test-server it works fine, which has me wondering if it could be some setting that I've missed in the IIS. If I navigate to the .asmx file and click the AddTab method I get a list of SOAP 1.1 and SOAP 1.2 XML, but not the HTTP POST request. If I navigate to it locally I get all three (SOAP 1.1, SOAP 1.2 and HTTP Post) The service is set up as follows: [WebService(Namespace = "mynamespace")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] [ScriptService()] public class Service : System.Web.Services.WebService { [WebMethod(EnableSession=true)] [ScriptMethod()] public void AddTab(string tab) { //Some code to add a tab which evidently works locally... } } Anyone have a clue what I'm missing here?

• How to get or own your own IP address?

  - by Cory

  The website we running let people register their own URL and redirect to our website to their user account. Lets it is something similar to Blogspot.com where users can have their own URL. The problem is that in order to do this we need to have static IP address for the DNS redirection to work. We can easily get static IP addresses from most hosting companies, but if we change our hosting company it means we will have to force all our users to change their DNS setting to our new IP address. This if very problematic. Is there a way of owning our own IP address that we can take it with us to wherever hosting company we decide to go with? Or there there other easier solutions out there?

• How can I make a security token automatically expire in a passive STS setup?

  - by Rising Star

  I have a passive STS set up for a new application I'm working on. I've noticed that when a user's session expires, the user is still authenticated. I would have thought that when the session expires, the user would no longer be authenticated. My boss discussed this with me as I am currently charged with setting up the authentication. He says that it would be good if we could make the user's log on expire after a certain period of inactivity similar to how the session expires. I am familiar with how to sign a user out with a few lines of code. How can I make it so that the user is automatically signed out after a specified period of inactivity? Currently, I have some code in the global.asax file that programmatically checks when the last request was and compares it to the current time; it then signs the user out if a certain period of time has expired.

• How to remove maximize button in Mac OS X tool window in Qt

  - by Andy Brice

  I have a floating tool window. It works fine on Windows, but I can't get rid of the maximise button on Mac OS X. I have tried unsetting Qt::WindowMaximizeButtonHint and setting the window to fixed size. Nothing seems to work. MyWidget::MyWidget( QWidget* parent ) :QWidget( parent, Qt::Tool | Qt::CustomizeWindowHint ) { setupUi( this ); setFixedSize( sizeHint() ); // doesn't remove maximise button setWindowFlags( windowFlags() & ~Qt::WindowMaximizeButtonHint ); // doesn't remove maximise button } I don't want to use a frameless window. Any ideas? I am using Qt 4.4.

• Flowlayout panel and autosizing child controls doesn't work

  - by Pete

  I am trying to get a very simple autosizing layout on a winform (C# .NET). I've tried TableLayoutPanels and FlowLayoutPanels but nothing works. I have a usercontrol which is a container for other usercontrols which are created at runtime - I've called it StackPanel as I want it to list the child controls vertically. I've tried this using a FlowLayoutPanel, TableLayoutPanel and a Panel (with each control docked to the top). The child usercontrol consists of a label and then any number of radiobuttons (or any other standard control - it doesn't matter). When the child controls are created, the label text is set (if this is long it needs to wrap to a new line) and the radio buttons are added. There seems to be no combination of docking/autosizing or manual size setting using the Resize events that can get everything to show without clipping and still resize with the form. Thanks!

• Xap file contents changes if built in Visual Studio or build server

  - by arch

  I'm using MEF with my Silverlight 4 app to dynamically load xap files. To optimize this process, I've removed various assemblies from my xaps since I know they've already been loaded by the base xap. This reduces the size of my dynamically loaded xaps. I accomplished this by setting the "Copy Local" flag for each assembly reference to "false". This all seems to work fine when I build in Visual Studio 2010 - my xaps are much smaller. However, when the same projects are built by the build server, all the excluded references are once again in the xap file hence tripling the size of the xap. I've read several blogs/articles regarding similar experiences but no resolution. Very frustrating - any help is appreciated.

• Is it possible to modify ASP.NET to no longer require runat="server"?

  - by sean2078

  I know why runat="server" is currently required (ASP.NET why runat="server"), but the consensus is that it should not be required if you incorporate a simple default into the design (I agree of course). Would it be possible to modify, extend, decompile and recreate, intercept or otherwise change the behavior of how ASP.NET parses ASPX and ASCX files so that runat="server" would no longer be required? For instance, I assume that a version of Mono could be branched to accomplish this goal. In case specific requirements are helpful, the following highlights one design: During parsing, when configured namespace tags are encountered (such as "asp"), default the element's runat property to "server" During parsing, when configured namespace tags are encountered (such as "asp"), if the element's runat property value is available, then that value should be used in place of the default New page-level setting introduced (can be set in the page directive or web.config) that specifies the default runat value for a specific namespace tag

• Sessionstate not being saved between pages

  - by Grant

  Hi, i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null. Sometimes it is set correctly and other times is is simply null. When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen. As it is based around the security of the site it is obviously important that the session data be valid and accurate every time. Is session state data unreliable? AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS. Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading? NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....

• How can I prevent users from taking screenshots of my application window?

  - by Midday

  What are some methods to prevent screenshots from being taken, if any? I've considered setting the "Print Screen" button as a hotkey, which makes the window fuzzy. However, there would be the problem of other 3rd party screenshot tools. How can I prevent their use? Why would I want such a thing? The idea is to create a chat client which you can't share the chatted information with others, not by copy & paste nor by print screen... Looking for general ideas or suggestions rather than actual code.

• How to handle concurrency control in ASP.NET Dynamic Data?

  - by Andrew

  I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

• Program skips code after trying to parse XML in VB.NET

  - by Bead

  I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

• *Best* way to forward/redirect a commonly mis-typed domain name

  - by m1755

  You own thecheesecakefactory.com and your site lives there. You know that many of your visitors will simply type cheesecakefactory.com into their browser, so you purchase that domain as well. What is the cleanest way of handling the redirection. I know GoDaddy offers a "domain forwarding" service but I am not sure if this is the "proper" way of handling it, and I don't necessarily like the idea of GoDaddy handling my DNS. My other option would be sending the domain to my DNS servers and possibly my actual server. Is it possible to do this without setting up a new vhost and a 301 redirect on my server (using DNS only)? If not, how does the GoDaddy forwarding service work?

• Scaling an Image in GWT

  - by Daniel

  Changing the size of an Image Widget in GWT changes the size of the image element, but does not rescale the image on the screen. Therefore, the following will not work: Image image = new Image(myImageResource); image.setHeight(newHeight); image.setWidth(newWidth); image.setPixelSize(newWidth, newHeight); This is because GWT implements its Image widget by setting the background-image of the HTML <img... /> element as the image, using CSS. How does one get the actual image to resize?

• Fast word count function in Vim

  - by Greg Sexton

  I am trying to display a live word count in the vim statusline. I do this by setting my status line in my .vimrc and inserting a function into it. The idea of this function is to return the number of words in the current buffer. This number is then displayed on the status line. This should work nicely as the statusline is updated at just about every possible opportunity so the count will always remain 'live'. The problem is that the function I have currently defined is slow and so vim is obviously sluggish when it is used for all but the smallest files; due to this function being executed so frequently. In summary, does anyone have a clever trick for producing a function that is blazingly fast at calculating the number of words in the current buffer and returning the result?

• Resizing page format on iReport

  - by pringlesinn

  I've been trying to print a pdf made from iReport in less than a page A4. it's like half A4 page height. I'm using a Line Matrix printer, doesn't matter which one. So, when I try to print 2 files at same file, it should print everything on the right place, but just first file is printed correctly. The second one is based on a A4 page format, and just starts printing after A4 page height is over, skipping a big blank. Where can I set the size of page in iReport? The only thing I could do was setting size of what is shown on screen while I edit the file. I tried my best to explain the situation, any doubts, ask me and I'll try even harder.

• Close box triggers validation for non-modal form

  - by Governor

  I have two form classes inheriting from a common base. One of the forms is called modally and the other non-modally. Validation is required on focus changes but not when the form is cancelled. When the Close Box is selected on the modal form it closes properly without any validation being triggered on it's controls. When the Close Box is selected on the non-modal form, validation events are triggered. A Cancel button with CausesValidation set false works fine in both cases. I have tried setting CausesValidation on the non-modal form to false but the problem remains. I should mention that the forms are mdi children. Any ideas? Thx.

• Drupal - editing tab options for a content type not showing up

  - by easement

  I'm working on a D5 site and a lot of the content types have the menus at the top of the edit page. Examples: Overview | Grants | Dev load | Dev render | Edit | Revisions | Track | Workflow Overview | Dev load | Dev render | Edit | Revisions | Track | Workflow | Node queue | RelatedContent I'm not sure where these tabs come from, but I need to enable the menu for a content type that doesn't have them visible. I checked the workflow setting and the content type in question was specified to use workflow. So there should be at least another tab in addition to edit. The end goal is to have revisions show up in the menu, but I need to get the menu showing first. Any ideas where to start looking?

• IE6 Not submitting POST Data?!

This site has worked on IE6 on a different windows server, it has worked on my laptop and works on all other major browsers (Firefox, Chrome, IE6,7,8, Safari) etc. Its just this one machine. Is there a setting not to allow post data on IE6? Thanks all

• Caching roles in a cookie

  - by AspOnMyNet

  1) a) I assume roles are cached ( by setting Roles.CacheRolesInCookie ) only for current user? b) Besides Roles.GetRolesForUser(_currentUser), are there any other methods that will read role information for current user from role cookie and thus won’t have to connect to the data base? 2) a) I assume that normally role cookie gets updated only when current user is added or removed from the role(s) or when the cookie expires? b) Because role names can be cached apart from the data source, it is possible that changes to role management at the data source would not be reflected in the cached values. In this case, the user must close and re-open their browser to clear the cached cookie value. How exactly could role cookie get cached apart from the data source? 3) If the number of roles cached in a role cookie equals the value of Roles.MaxCachedResults, then I assume when Roles.GetRolesForUser (_currentuser) gets called, it will need to check the DB to see whether user is also a member of any additional roles? thanx

• Invoking play on a QTMovie causes screensaver to deactivate on Snow Leopard

  - by ressaw

  I'm trying to port a working Leopard screensaver to Snow Leopard but it's deactivating after about half a second. The screensaver seems to deactivate upon invoking play on a QTMovie. And it deactivates both upon -play on the QTMovie object itself, and -play:self on the QTMovieView. If I don't actually call -play on the object, the screensaver does not deactivate and sits still on the first frame of the movie. Setting up the same code in a regular Cocoa Application works fine, and the screensaver also works fine in preview mode in the System Preferences. Any help is greatly appreciated.
