wpf usercontrol within usercontrol with the help of region manager

- by Miral

Sorry for weird title, actually i can only explain my question but cannot put in a few words in the title. I am developing WPF Composite application with PRISM approach. I have got a common WPF usercontrol which is gonna be used by all other usercontrol, i.e. usecontrol within a usercontrol. The common usercontrol has got a button "ProcessMultiple" which I want it to behave differently from all usercontrol. I am using RegionManager to add this views. I have got PresentationModel for all the usercontrol IRegion historyUpdaterRegion = _regionManager.Regions["HistoryUpdaterRegion"]; IRegionManager historyUpdaterRegionManager = historyUpdaterRegion.Add(_unityContainer.Resolve<IHistoryDocumentUpdaterPresentationModel>().View, null, true); historyUpdaterRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View); IRegion refundArrivalRegion = _regionManager.Regions["RefundArrivalRegion"]; IRegionManager refundArrivalRegionManager = refundArrivalRegion.Add(_unityContainer.Resolve<IRefundArrivalProcessorPresentationModel>().View, null, true); refundArrivalRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View);

.NET Code Generataion | Unable to create a T4 template in Visual Studio 2008

- by cedar715

I've the Visual Studio 2008 installed on my machine(licensed one). When I try to add a new .tt(say bar.tt) file to the project, the following code is generated: I've seen in a screencast, where in an empty .tt file should be opened and the developer enters the T4 code. Even if I remove the code and enter T4 code, am getting build errors. using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Linq; using System.Reflection; using System.Windows.Forms; namespace Foobar { partial class bar : Form { public bar() { InitializeComponent(); this.Text = String.Format("About {0} {0}", AssemblyTitle); this.labelProductName.Text = AssemblyProduct; this.labelVersion.Text = String.Format("Version {0} {0}", AssemblyVersion); this.labelCopyright.Text = AssemblyCopyright; this.labelCompanyName.Text = AssemblyCompany; this.textBoxDescription.Text = AssemblyDescription; } #region Assembly Attribute Accessors public string AssemblyTitle { get { object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyTitleAttribute), false); if(attributes.Length > 0) { AssemblyTitleAttribute titleAttribute = (AssemblyTitleAttribute)attributes[0]; if(titleAttribute.Title != "") { return titleAttribute.Title; } } return System.IO.Path.GetFileNameWithoutExtension(Assembly.GetExecutingAssembly().CodeBase); } } public string AssemblyVersion { get { return Assembly.GetExecutingAssembly().GetName().Version.ToString(); } } public string AssemblyDescription { get { object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false); if (attributes.Length == 0) { return ""; } return ((AssemblyDescriptionAttribute)attributes[0]).Description; } } public string AssemblyProduct { get { object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyProductAttribute), false); if (attributes.Length == 0) { return ""; } return ((AssemblyProductAttribute)attributes[0]).Product; } } public string AssemblyCopyright { get { object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyCopyrightAttribute), false); if (attributes.Length == 0) { return ""; } return ((AssemblyCopyrightAttribute)attributes[0]).Copyright; } } public string AssemblyCompany { get { object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyCompanyAttribute), false); if (attributes.Length == 0) { return ""; } return ((AssemblyCompanyAttribute)attributes[0]).Company; } } #endregion } } EDIT: I didn't download any T4 software separately as I got to know that it already ships with Visual Studio 2008.

Problem using void pointer as a function argument

- by Nazgulled

Hi, I can't understand this result... The code: void foo(void * key, size_t key_sz) { HashItem *item = malloc(sizeof(HashItem)); printf("[%d]\n", (int)key); ... item->key = malloc(key_sz); memcpy(item->key, key, key_sz); } void bar(int num) { foo(&num, sizeof(int)); } And I do this call: bar(900011009); But the printf() output is: [-1074593956] I really need key to be a void pointer, how can I fix this?

UINavigationController does not set view properties correctly when pushed

- by Sheehan Alam

I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

iPhone:Tabbar item actions are not happening

- by user187532

Hello all, I created a window application, which has a tabbar controller with four tabbar items. Each tabbar items are linked with a tableview. I have also set Navigation bar for each tabbar items. I have appdelegate file, which calls the first tableview controller of which is set for first tabbar item. I am trying to retrieve and do an action whenever a tabbar item is clicked. For that, i tried to add "- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item" and "- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UITableViewController *)viewController" in my first tableview controller, but it is not at all responding whenever i click any tabbar items. My question is, if i create a window based application and added tabbar controller, tableview and navigation bar in .XIB file, is it not possible to access and do an action programatically whenever a tabbar item is clicked? (or) Am i doing anything wrong? Please help me to resolve this and share your ideas. Thanks.

Posting XML via curl (command-line) without using key/value pairs

- by Mathias Bynens

Consider a PHP script that outputs all POST data, as follows: <?php var_dump($_POST); ?> The script is located at http://example.com/foo.php. Now, I want to post XML data to it (without using key/value pairs) using command line curl. I have tried many variations of the following: curl -H "Content-type: text/xml; charset=utf-8" --data-urlencode "<foo><bar>bazinga</foo></bar>" http://example.com/foo.php Yet none of them seem to actually post anything — according to the PHP script, $_POST is just an empty array. What am I doing wrong here?

Using Android SAXParser, one my my XML Elements is mysteriously breaking in half.

- by Drennen

And its not '&' Im using the SAXParser object do parse the actual XML. This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method. However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one. This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level" <title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title> When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine. Something about StringReader and or InputSource is somehow screwing this up. Here is my method that takes and XML string and parses is through the SAXParser. public void parseXML(String XMLstring) { try { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); xr.setContentHandler(this); // Something is happening in the StringReader or InputSource // That cuts the XML element in half at the 2001 character mark. StringReader sr = new StringReader(XMLstring); InputSource is = new InputSource(sr); xr.parse(is); } catch (IOException e) { Log.e("CMS1", e.toString()); } catch (SAXException e) { Log.e("CMS2", e.toString()); } catch (ParserConfigurationException e) { Log.e("CMS3", e.toString()); } } I would greatly appreciate any ideas on how to not have 'characters' firing off twice when I get to this point in the XML String. Or, show me how to use a POST request and still pass off the URL to the Parse function. THANK YOU.

Opening a local file in Eclipse from the web

- by Victor Nicollet

Right now, when I notice a problem on a page on my PHP web site, I have to look at the URL, mentally deduce what file is responsible for displaying that page, then navigate the Eclipse PDT file tree to open that file. This is annoying and uses brain power that could have been applied to solving the issue instead. I would like my PHP web site to display on every page a link that I could click to automatically open the correct file in Eclipse. I can easily compute the complete absolute path for the file I need to open (for example, open C:/xampp/htdocs/controllers/Foo/Bar.php when visiting /foo/bar), and I can make sure that Eclipse is currently open with the correct project loaded, but I'm stuck on how I can have Firefox/Chrome/IE tell Eclipse to open that specific file.

Where did my Toolbar button go?

- by Driss Zouak

When MyView gets pushed on to the NavigationController, I have the following code public override void ViewDidLoad () { this.NavigationController.Toolbar.SetItems(new UIBarButtonItem[] { new UIBarButtonItem("Next",UIBarButtonItemStyle.Plain, ClickNext) }, true); this.NavigationItem.Title = "Proposal Plan - Step 1"; } The Title gets set properly, and the code runs but in my Toolbar at the bottom of the view I don't have the "Next" button I am expecting. I put a breakpoint and verified that the Toolbar after running that line does have my button, but still nothing. What am I mising?

FullText Search using multiple tables in SQL

- by Caesar

Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?

- by iPhone Developer

I have used the code below to create a button on the nav bar with an image. I can see the image but I can also see the border of the button around it.

Any pointers, links to read further or examples appreciated.

jQuery ajax doesn't seem to be reading HTML data in Chromium

- by Mahesh

I have an HTML (App) file that reads another HTML (data) file via jQuery.ajax(). It then finds specific tags in the data HTML file and uses text within the tags to display sort-of tool tips. Here's the App HTML file: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US"> <head> <title>Test</title> <style type="text/css">  </style> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script> <script type="text/javascript"> //<![CDATA[ $(document).ready(function() { $("#stat_preview").hide(); $(".cfg_lnk").mouseover(function () { lnk = $(this); $.ajax({ url: lnk.attr("href"), success: function (data) { console.log (data); $("#stat_preview").html("A heading<br>") .append($(".tool_tip_text", $(data)).slice(0,3).text()) .css('left', (lnk.offset().left + lnk.width() + 30)) .css('top', (lnk.offset().top + (lnk.height()/2))) .show(); } }); }).mouseout (function () { $("#stat_preview").hide(); }); }); //]]> </script> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <h1>Test</h1> <ul> <li><a class="cfg_lnk" href="data.html">Sample data</a></li> </ul> <div id="stat_preview"></div> </body> </html> And here is the data HTML <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US"> <head> <title>Test</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <h1>Test</h1> <table> <tr> <td class="tool_tip_text"> Some random value 1</td> <td class="tool_tip_text"> Some random value 2</td> <td class="tool_tip_text"> Some random value 3</td> <td class="tool_tip_text"> Some random value 4</td> <td class="tool_tip_text"> Some random value 5</td> </tr> <tr> <td class="tool_top_text"> Some random value 11</td> <td class="tool_top_text"> Some random value 21</td> <td class="tool_top_text"> Some random value 31</td> <td class="tool_top_text"> Some random value 41</td> <td class="tool_top_text"> Some random value 51</td> </tr> </table> </body> </html> This is working as intended in Firefox, but not in Chrome (Chromium 5.0.356.0). The console.log (data) displays empty string in Chromium's JavaScript console. Firebug in Firefox, however, displays the entire data HTML. Am I missing something? Any pointers?

Download HTML and Images with WGet without first few lines

- by St. John Johnson

I'm attempting to use wget with the -p option to download specific documents and the images linked in the HTML. The problem is, the site that is hosting the HTML has some non-html information preceding the HTML. This is causing wget to not interpret the document as HTML and doesn't search for images. Is there a way to have wget strip the first X lines and/or force searching for images? Example URL: http://www.sec.gov/Archives/edgar/data/13239/000119312510070346/ds4.htm First Lines of Content: <DOCUMENT> <TYPE>S-4 <SEQUENCE>1 <FILENAME>ds4.htm <DESCRIPTION>FORM S-4 <TEXT> <HTML><HEAD> <TITLE>Form S-4</TITLE> Last Lines of Content: </BODY></HTML> </TEXT> </DOCUMENT>

UITabBar in iPad - Won't go into landscape mode with more than 2 items

- by Sam Diaz

I created a new project and selected the Tab Bar template for iPad. I opened it up in Interface Builder and added 4 more items, bringing the total items to 6. I did a build and run and it opened up fine in the iPad simulator, but it wouldn't go into landscape! I then backtracked in interface builder and found that it would go landscape if there were only 2 items in the tab bar, but not if there were any more. The simulator rotates but all the content (currently just the placeholders put in place by Apple) stays as if it was portrait. Any ideas why?

htaccess mask dynamic url with a static url

- by Enkay

I'm trying to do something with .htaccess that I'm not sure can be done. First thing I did is hide the .php extensions using the following code: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php Works great. Now what I'm trying to do and can't seem to figure out is the following: When a user types "mywebsite.com/products?id=12345" into the browser address bar, I want the server to serve the right product page according to the ID but display it in the address bar as "mywebsite.com/product" no matter what the product ID is. Is this possible to do? If yes how? Thanks

Customizing UIPickerView

- by Raj

Hi all, I have a requirement where UIPickerView should be customized. The picker view should look something like this: The application which has customized the pickerView similarly is: http://itunes.apple.com/us/app/convert-the-unit-calculator/id325758140?mt=8 I have tried removing the default pickerView selection bar by resetting the property showsSelectionIndicator of UIImagePicker and adding a overlay view. But the problem is, the overlay view should be transparent so that the wheel behind it is visible. But the other application somehow does it even though the selection bar is not transparent. Any ideas on how to achieve this feat? Thanks and Regards, Raj

CSS - 100% Height Layout with Variable Height Header

- by Brian D.

The layout I want to achieve is pretty simple. I want a 100% height layout with a header, and below the header I will have a side bar for navigation and then the content area beside the navigation bar (2-column with header). I can easily do this if I give the header a specified height but I want the header to just take up as much room as is needed. Does anyone know how to do this? Is it possible without knowing the height of the header? Thanks for any help.

Where/what is the specification for odata.service meta tag?

- by Sam Saffron

I would like to add some tags to our web app to enable auto-discovery of our odata feeds. So for example Nerd Dinner has the following tag: <link rel="odata.service" title="NerdDinner.com OData Service" href="/Services/OData.svc" /><link rel="odata.feed" title="NerdDinner.com OData Service - Dinners" href="/Services/OData.svc/Dinners" /> The trouble is that I have 4 different feeds and am unclear if I am allowed to add multiple link rel="odata.service" to the document. Where is the specification for this meta tag? (follow on question, are there any apps that take advantage of this tag that I can use to test out behavior)

Reference custom list form fields from code behind and automatically fill them with values.

- by Janis Veinbergs

Hello. I`v made my custom NewForm.aspx for my list and I want to add some custom code to it. So I inherit that form from my own class: public class MyCustomNewForm : Microsoft.SharePoint.WebPartPages.WebPartPage Now I want to reference some of available fields to automatically fill them for user. (Javascript won't help here as I have to get some data from other lists). But I have no idea how do I reference these fields from codebehind files. The code for control field is written (well, it was generated by Sharepoint Designer when using command Insert SharePoint Controls Custom List Form...) in .aspx page like this: <SharePoint:FormField runat="server" id="ff1{$Pos}" ControlMode="New" FieldName="Title" __designer:bind="{ddwrt:DataBind('i',concat('ff1',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}"/> When looking at id at runtime, it is insanely long So how do i reference fields, so I could set Text property on them in my codebehind file?

switch views using a button, going to a table view, iphone

- by Jaime Rae

My program has 4 buttons and each button calls a different table view. That works fine, but my problem is, the view controller I'm using brings up a table view that covers up my navigation bar and my tab bar. I need to replace that coding with something that will bring up a table and not cover up my nav and tab bars. Here is the coding I'm using: -(IBAction)buttonNorthWest { NorthWestViewController *nwController = [[NorthWestViewController alloc] initWithNibName:@"NorthWestView" bundle:nil]; self.nwViewController = nwController; [self.view insertSubview:nwViewController.view atIndex:0]; [self presentModalViewController:nwViewController animated:YES]; [nwController release]; } The [self presentModalViewController....] is the problem. Does anyone know how I can replace that code with something that keeps my nav and tab bars? Thanks, Jaime

Asp.Net Mvc JQuery ajax input parameters are null

- by Dofs

Hi, I am trying to post some data with jQuery Ajax, but the parameters in my Ajax method are null. This is simple test to send data: var dataPost = { titel: 'titel', message: 'msg', tagIds: 'hello' }; jQuery.ajax({ type: "POST", url: "Create", contentType: 'application/json; charset=utf-8', data: $.toJSON(dataPost), dataType: "json", success: function(result) { alert("Data Returned: "); } }); And my Ajax method looks like this: [HttpPost] public ActionResult Create(string title, string message, string tagIds) {... } There is something basic wrong with the data I send, but I can't figure out what. All the time the title, message and tagIds are null, so there is something wrong with the encoding, I just don't know what. Note: The jQuery.toJSON is this plugin

Importing Conditionally Compiled Functions From a Perl Module

ReadOnlyCollection or IEnumerable for exposing member collections?

- by Erik Öjebo

Is there any reason to expose an internal collection as a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection? class Bar { private ICollection<Foo> foos; // Which one is to be preferred? public IEnumerable<Foo> Foos { ... } public ReadOnlyCollection<Foo> Foos { ... } } // Calling code: foreach (var f in bar.Foos) DoSomething(f); As I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does not allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something? Thanks /Erik
