  • Why is my image being displayed larger?

    - by bsh152s
    I'm trying to display an image on a splash screen and it's being stretched upon display. The image I'm trying to display is a simple bmp file. Any ideas why? In SplashWindow.xaml: <Window ... SizeToContent="WidthAndHeight"> <Grid> ... <Image Grid.Row="0" Source="{Binding SplashImage}"></Image> </Grid> </Window> In SplashViewModel.cs public ImageSource SplashImage { get { return ImageUtilities.GetImageSource(_splashImageFilenameString); } } From ImageUtilities.cs public static ImageSource GetImageSource(string imageFilename) { BitmapFrame bitmapFrame = null; if(!string.IsNullOrEmpty(imageFilename)) { if(File.Exists(imageFilename)) { bitmapFrame = BitmapFrame.Create(new Uri(imageFilename)); } else { Debug.Assert(false, "File " + imageFilename + " does not exist."); } } return bitmapFrame; }

    - by sajad
    Hi Friends, I want to write a code to search for method defination and methods called in a c# file. So obviously my pattern should search for text like 1.public void xyz(blahtype blahvalue); 2.string construct = SearchData(blahvalue); Has anyone done similar to this, is Regex helpful in this case. if yes provide me the pattern. Any other workarounds. I dont know reflection(will it help in my case) Thanks, you guys gave it a try, i did not know this wud be so complex. All i wanted to do was suppose i have method like this public method1(int val) { method2(); method3(); } void method2(int val2) { method4() } i wanted to construct a string as Method1:Method2:method4 and Method1:Method3.... I guess its really complex

  • Searching a table MySQL & PHP.

    - by S1syphus
    I want to be able to search through a MySQL table using values from a search string, from the url and display the results as an XML output. I think I have got the formatting and declaring the variables from the search string down. The issue I have is searching the entire table, I've looked over SO for previous answers, and they all seem to have to declare each column in the table to search through. So for example my database layout is as follows: **filesindex** -filename -creation -length -wall -playlocation First of all would the following be appropriate: $query = "SELECT * FROM filesindex WHERE filename LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE creation LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE length LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE wall LIKE '".$searchterm."%' UNION SELECT * FROM filesindex WHERE location LIKE '".$searchterm."%'"; Or ideally, is there an easier way that involves less hardcoding to search a table. Any ideas? Thanks

  • [Android] accessing another Activity's preferences

    - by Raffaele
    I have a Login Activity which stores credentials in its own SharedPreferences; then I added two getters for reading them, something like public String getUsername() { return getPreferences(MODE_PRIVATE).getString("#username", null); } but this throws a NPE when I call it like this String mUser = (new Login()).getUsername(); It seems that the Activity cannot read its preferences after a simple contructor call, as if it were in some uncompleted state. I read lots of related topics, but wasn't able to find a solution. Basically, I need to share these credentials among activities in my application

  • Why can I not add a set accessor to an overriden property?

    - by Svish
    In a base class I have this property: public virtual string Text { get { return text; } } I want to override that and return a different text, but I would also like to be able to set the text, so I did this: public override string Text { get { return differentText; } set { differentText = value; } } This however does not work. I get a red squiggly under set saying that I can not override because it does not have a set accessor. Why is this aproblem? What should I do?

  • Python: Dynamic attribute name generation without exec() or eval()

    - by PyNewbie27
    Hi, I'm trying to dynamically create buttons at runtime with PyQT4.7 However, this being my first python program I'm not sure how to get the functionality I want. I would like to be able to substitute a text string for an attribute name: i.e. for each in xrange(4): myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2 #self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button #here's where I get stuck. this code isn't valid, but it shows what i want to do self.ui.gridLayout.addWidget(self.ui.%s) % myname #I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement? I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)

  • I have a question about URI templates in WCF Services

    - by Debby
    I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.

  • Problem with jQuery accordion and cookies

    - by rayne
    I have a jQuery accordion from this site and edited for my purposes, but the accordion only works in Firefox (not Safari or Chrome) and the cookies aren't being set correctly. This is the jQuery: function initMenus() { $('#sidebar .letter_index').hide(); $.each($('#sidebar .letter_index'), function() { var cookie = $.cookie(this.id); if (cookie === null || String(cookie).length < 1) { $('#sidebar .letter_index:first').show(); } else { $('#' + this.id + ' .' + cookie).next().show(); } }); $('#sidebar .letter_head').click(function() { var checkElement = $(this).next(); var parent = this.parentNode.parentNode.id; if ((checkElement.is('.letter_index')) && (!checkElement.is(':visible'))) { $('#' + parent + ' .letter_index:visible').slideUp('normal'); if ((String(parent).length > 0) && (String(this.className).length > 0)) { // not working - wie ändert man das this.class so das die class abc oder def gesetzt wird anstatt this?! $.cookie(parent, this.className); } checkElement.slideDown('normal'); return false; } } ); } $(document).ready(function() {initMenus();}); This is how my HTML looks (sample item): <div id="sidebar"> <h2 class="letter_head"><a href="#" class="ABC">ABC</h2> <ul class="letter_index"> <li>Abc</li> <li>Bcd</li> </ul> </div> I can't find the problem why the script won't work in Safari and Chrome. I also don't know how to tell it to use the class of the a inside the h2 as the cookie value. (Currently the cookie is set as $.cookie(parent, this.className);, which produces cookies with the name container (the div above #sidebar) and the value letter_head. It needs to be something like 'sidebar' and 'ABC', 'DEF' and so on. Thanks in advance!

  • Can Symfony simply reload a page request?

    - by Rob Wilkerson
    I have an app that receives a request from another app. It detects a value on the query string, checks that value against a cached value and, if they don't match, it needs to clear its cache and reload the page (establishing a new cache). Unfortunately, I can't find a way to tell Symfony to redirect to the current page in exactly the same format (protocol, URI path, query string, etc.). What am I missing? This is all happening in a filter on isFirstCall(). Thanks.

  • Why is the EntityManager in my GAE + Spring (+graniteds) project reset to null?

    - by prefabSOFT
    Hi all, I'm having a problem with autowiring my EntityManager. Actually at server startup I can see that the injection works ok, though when trying to use my EntityManager it appears to be null again. @Component public class DataDaoImpl { protected EntityManager entityManager; @Autowired public void setEntityManager(EntityManager entityManager) { System.out.println("Injecting "+entityManager); //works! this.entityManager = entityManager; } public void createData(String key, String value) { System.out.println("In createData entityManager is "+entityManager); //entityManager null!? ... Output: Injecting org.datanucleus.store.appengine.jpa.DatastoreEntityManager@a60d19 The server is running at http://localhost:8888/ In createData entityManager is null So somehow the autowired entityManager is reset to null when trying to use it. It's a graniteds powered project though I don't think this is graniteds related. Any ideas? Thanks a lot in advance, Jochen

  • Java regex basic usage problem

    - by Ernelli
    The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

  • Mapping child objects in fluent nhibernate to a read-only view

    - by grenade
    Given that I am implementing a read-only UI, how do I create a ClassMap for Shop: public class Shop { public int Id { get; set; } public City City { get; set; } } public class City { public string Name { get; set; } public string CountryCode { get; set; } } The DB interface for Shops is a View containing 3 columns (ShopId, CityName, CountryCode). I was hoping to do something like this: public sealed class ShopMap : ClassMap<Shop> { public ShopMap() { Table("Shop"); Id(x => x.Id, "ShopId"); Map(x => x.City.Name, "CityName"); Map(x => x.City.CountryCode, "CountryCode"); } } Will fluent auto-instantiate Shop.City?

  • DataTable Delete Row and AcceptChanges

    - by Pang
    DataTable DT num type name =================================== 001 A Peter 002 A Sam 003 B John public static void fun1(ref DataTable DT, String TargetType) { for (int i = 0; i < DT.Rows.Count; i++) { string type = DT.Rows[i]["type"]; if (type == TargetType) { /**Do Something**/ DT.Rows[i].Delete(); } } DT.AcceptChanges(); } My function get specific data rows in datatable according to the TargetType and use their info to do something. After the datarow is read (match the target type), it will be deleted. However, the row is deleted immediately after .Delete() execute, so the location of the next row (by i) is incorrect. For example, if TargetType is A. When i=0, the "Peter" row is deleted after .Delete executed. Then when i=1, I suppose it will locate the "Sam" row but it actually located "John" row because "Peter" row is deleted. Is there any problem in my codes?

  • Using Jquery $getJSON How do I dynamically create data for the [data] parameter after Url param?

    - by Breadtruck
    I have no problems getting the Json to work and parse the json return. I was just wondering how I could build a dynamic "whatever data is" and stick it into [data] to pass my parameters from there and not manually append them to the url. From jquery website example: $.getJSON("test.js", { name: "John", time: "2pm" }, function(json){ alert("JSON Data: " + json.users[3].name); }); I thought I could build a string ( which doesn't make sense anyway ) and drop it inside the { }, but I obviously don't understand that part. name: isn't a string and you can't put a variable in that part, so how would I dynamically put items into whatever [data] is.
