  • I have a custom type which i want to serialize, this custom type accepts input which might consists

    - by starz26
    I have a custom type which i want to serialize, this custom type accepts input which might consists of escape chars. M1_Serilizer(MyCustomType customTypeObj) {XmlSerializer serializer = new XmlSerializer(typeof(MyCustomType)); StringWriter sw = new StringWriter(CultureInfo.InvariantCulture); serializer.Serialize(sw, customTypeObj); string str= sw.ToString(); M2_Deserializer(str); } M2_Deserializer(string str) { XmlSerializer serializer = new XmlSerializer(typeof(MyCustomType)); StringReader sr = new StringReader(str); MyCustomType customTypeObj = (MyCustomType)serializer.Deserialize(sr); } when escape type chars are part of the CustomTypeObj, on deserialization it throws an exception. Q1)How do i overcome this?, Q2)I should use StringReader and StringWriter and not memorystream or other thing ways. StringWriter/reader will only serve my internal functionality Q3)How can these escape chars be handled?

  • assembly.GetTypes() does not return all types

    - by meta
    I try to lead the types from an .dll (which is also referenced in the executing project). I call: public static void LoadPlugin(string pluginFile) { Assembly assembly = Assembly.LoadFrom(pluginFile); foreach (Type type in assembly.GetTypes()) { // play with it } } It loads just a few of them: public partial class Mathematics : UserControl, IMathematics, IPortable and public partial class Welcome : UserControl but the next one, and some others, are ignored: public partial class Test : UserControl, ITest, IPortable They all stand in the same assembly, under the same namespace. The public static void LoadPlugin(string pluginFile) method is located in other assembly that is also referenced in the executing project. No exceptions are thrown. What could be the issues for not loading all the types? Any ideas?

  • Default http/admin port in dropwizard project

    - by mithrandir
    I have a dropwizard project and I have maintained a config.yml file at the ROOT of the project (basically at the same level as pom.xml). Here I have specified the HTTP port to be used as follows: http: port:9090 adminPort:9091 I have the following code in my TestService.java file public class TestService extends Service<TestConfiguration> { @Override public void initialize(Bootstrap<TestConfiguration> bootstrap) { bootstrap.setName("test"); } @Override public void run(TestConfiguration config, Environment env) throws Exception { // initialize some resources here.. } public static void main(String[] args) throws Exception { new TestService().run(new String[] { "server" }); } } I expect the config.yml file to be used to determine the HTTP port. However the app always seems to start with the default ports 8080 and 8081. Also note that I am running this from eclipse. Any insights as to what am I doing wrong here ?

  • [iphone] use NSString in other method?!

    - by user134282
    It's really embarrassing but i stuck on it for two hours of trial and error. I declared an NSString in the interface as: NSString *testString; Then i made a property and synthesized it. I allocate it in viewDidLoad with: testString = [[NSString alloc] initWithFormat:@"thats my value: %i", row]; If i want to get the value of the string in another method it always return (null). So the string is empty, but why? how do i make it accessible for every function inside of one class? So i don't want to make a global var just a "global variable inside the class" It's really confusing because as long as i code i never ran into this problem :( thanks a lot for helping me!

  • C# Get/Set Syntax Usage

    - by RoR
    These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

  • How to change Session for only one route in asp.net mvc?

    - by denis_n
    How to handle Application_BeginRequest using a custom filter in asp.net mvc? I want to restore session only for one route (~/my-url). It would be cool, if I could create a custom filter and handle that. protected void Application_BeginRequest(object sender, EventArgs e) { var context = HttpContext.Current; if (string.Equals("~/my-url", context.Request.AppRelativeCurrentExecutionFilePath, StringComparison.OrdinalIgnoreCase)) { string sessionId = context.Request.Form["sessionId"]; if (sessionId != null) { HttpCookie cookie = context.Request.Cookies.Get("ASP.NET_SessionId"); if (cookie == null) { cookie = new HttpCookie("ASP.NET_SessionId"); } cookie.Value = sessionId; context.Request.Cookies.Set(cookie); } }

  • Javascript: Retrieve Object Property Names

    - by Jason
    I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

  • Design classes/interface to support methods returning different types

    - by Nayn
    Hi, I have classes as below. public interface ITest <T> { public T MethodHere(); } public class test1 implements ITest<String> { String MethodHere(){ return "Bla"; } } public class test2 implements ITest<Integer> { Integer MethodHere(){ return Integer.valueOf(2); } } public class ITestFactory { public static ITest getInstance(int type) { if(type == 1) return new test1(); else if(type == 2) return new test2(); } } There is a warning in the factory class that ITest is used as raw type. What modification should I do to get rid of it? Thanks Nayn

  • Value of Step-by-Step Asserts in Unit Tests

    - by Eric J.
    When writing unit tests, there are cases where one can create an Assert for each condition that could fail or an Assert that would catch all such conditions. C# Example: Dictionary<string, string> dict = LoadDictionary(); // Optional Asserts: Assert.IsNotNull(dict); Assert.IsTrue(dict.Count > 0); Assert.IsTrue(dict.ContainsKey("ExpectedKey")); // Condition actually interested in testing: Assert.IsTrue(dict["ExpectedKey"] == "ExpectedValue"); Is there value to a large, multi-person project in this kind of situation to add the "Optional Asserts"? There's more work involved (if you have lots of unit tests) but it will be more immediately clear where the problem lies. I'm using VS 2010 and the integrated testing tools but intend the question to be generic.

  • Read video information(date created)?

    - by Lynx
    In window, i can get the date created of the video from properties(right click). I have a few idea on this but i dont know how to do it. 1. Get the video information directly from video(like in windows), 2. By extracting the video name to get the date created(The video's name is in date format, which is the time it created). And i also using taglib-sharp to get the video duration and resolution, but i cant find any sample code on how to get the video creation date. Note: video name in date format - example, 20121119_125550.avi Edit Found this code and so far its working string fileName = Server.MapPath("//video//20121119_125550.avi"); FileInfo fileInfo = new FileInfo(fileName); DateTime creationTime = fileInfo.CreationTime; Output: 2012/11/19 12:55:50 For the file's name, i will add another string in name. For example User1-20121119_125550.avi.avi, so it will get complicated after that.

  • Progress Dialog on open activity

    - by GeeXor
    hey guys, i've a problem with progress dialog on opening an activity (called activity 2 in example). The activity 2 has a lot of code to execute in this OnCreate event. final ProgressDialog myProgressDialog = ProgressDialog.show(MyApp.this,getString(R.string.lstAppWait), getString(R.string.lstAppLoading), true); new Thread() { public void run() { runOnUiThread(new Runnable() { @Override public void run() { showApps(); } }); myProgressDialog.dismiss(); } }.start(); The showApps function launch activity 2. if i execute this code on my button click event on activity 1, i see the progress, but she doesn't move and afeter i have a black screen during 2 or 3 seconds the time for android to show the activity. If i execute this code in the OnCreate of Activity2 and if i replace the showApps by the code on OnCreate, Activity1 freeze 2 seconds, i don't see the progress dialog, and freeze again 2 seconds on activity 2 before seeing the result. An idea ?

  • Is there a method to retrieve the file name of a class?

    - by Dran Dane
    Hello Is there a method to retrieve the file name of a class? Specifically I would like to create a static method (CreateLink) in a base class (BasePage) to automatically return the path and filename of the page called. I code in .C# ASP.NET private const string TEMPLATE = "~/One.aspx"; public static HyperLink CreateLink() { HyperLink link = new HyperLink(); link.Text = "Click here"; link.NavigateUrl = String.Format(TEMPLATE); return link; } Is it possible to avoid the use of TEMPLATE hardcoded variable? Is it possible to retrieve the One.aspx path from file name and location?

  • Unable to pass attribute from controller to view

    - by MDS
    I'm using Spring MVC 3 for a web app. In the app a URI template is supposed to be handled by a controller method, which then passes an attribute to a view. Currently, the controller does handle the request, and it even forwards to the correct view. However, it does NOT pass the attribute to the view. Below are the URI template, controller method and relevent jsp tags. Anyone see what is wrong? URI: /home/{status} Controller: @RequestMapping("/home") @Controller public class HomeController { ... ... @RequestMapping(value="/{status}") public String homeStatusView(@PathVariable("status") String status, ModelMap model) { model.addAttribute("status", status); return "home"; } } JSP: ... <c:if test="${not empty status}"> <span class="status">Your status is available...</span> </c:if> ...

  • Trying to send XML via EMail and the XML includes a byte[]

    - by barbary
    Hello All, I want to send an email that has a machine readable part you cut and paste into an asp.net page and you get the information. I have stored all the information in an object and then used an XMLSerizer to create some xml. It all worked fine until I added some Images as byte[] to the object. If I dump the resulting string to disk then I can recreate the object fine but after it appears in the email client and I try to cut and paste it it never works. Clearly there are non standard characters coming out that email clients don't like. Is there some encoding I could apply to my XML that would make it display correctly in an email client? Then I could cut, paste, decode and deserilize to get my object back. Please an example of how to encode the string in c# would be great.

  • NullPointerException while trying to bind at SimpleCursorAdapter

    - by hrskrs
    I have asked a question before where i found my mistake. However now i am facing with another problem. I have checked all the similar errors asked on StackOverflow but without success.Any help is appriciated. The idea here is that i am getting image names from DB so depending on those names images from Drawable folder will be shown in a listView together with a description but im getting an error of NullPointException at setViewValue. Here is the code snippet: private void populateListView() { ListView customListView = (ListView)findViewById(R.id.lvCustom); Cursor cursor = DBhelper.getAllimages(); startManagingCursor(cursor); String[] from = { DBhelper.COLUMN_PIC_URL, DBhelper.COLUMN_PIC_DESC}; int[] to = {R.id.ivImg, R.id.tvTitle}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.custom_listview_row, cursor, from, to, 0); cursorAdapter.setViewBinder(new ViewBinder() { @Override public boolean setViewValue(View view, Cursor cursor, int columnIndex) { ImageView imageImageView = (ImageView)findViewById(R.id.ivImg); String[] imgNames = new String[cursor.getCount()]; int[] imgResourceIds = new int[cursor.getCount()]; for(int i=0; i<cursor.getCount(); i++){ imgNames[i] = cursor.getString(cursor.getColumnIndex(DBhelper.COLUMN_PIC_URL)); imgResourceIds[i] = getResources().getIdentifier(imgNames[i], "drawable", getPackageName()); imageImageView.setImageResource(imgResourceIds[i]); cursor.moveToNext(); } return true; } }); customListView.setAdapter(cursorAdapter); } Here is the Error from LogCat: I have tried to log the output of imgNames[i] where it returns the url pic from the DB correctly and imgResourceIds[i] where it return the image resource id correctly also(it does not return NULL but something like: 295731). But it stops at imageImageView.setImageResource(imgResourceIds[i]); To see from where that NullPointerException is coming, i commented out imageImageView.setImageResource(imgResourceIds[i]);. This time imageNames(those with a TAG) and imgResourceIds(those system printed out) came correctly but doubled, when i removed cursor.MoveToNext() last row were doubled. Here is the screen shot of that: I have tried all the suggestions on stack about gettin a NullException but without success. Any idea where i am doing mistake?

  • what to use in place of std::map::emplace?

    - by kfmfe04
    For containers such as std::map< std::string, std::unique_ptr< Foo >>, it looks like emplace() has yet to be implemented in stdc++ as of gcc 4.7.2. Unfortunately, I can't store Foo directly by value as it is an abstract super-class. As a simple, but inefficient, place-holder, I've just been using std::map< std::string, Foo* > in conjunction with a std::vector< std::unique_ptr< Foo >> for garbage collection. Do you have a interim solution that is more efficient and more easily replaced once emplace() is available?

  • C# RichTextBox - Partially setting DetectUrls=false

    - by Suds
    Hi, I have this RichTextBox and I have embedded some http links in it. I have set DetectUrls = true, and it displays the links correctly and handles in the event. In the same RichTextBox, I have one more string displayed which looks like this Type http://< Your host name Now, since DetectUrls= true, the portion "http://<" is displayed as a link, while I want this to be text. If I set the DetectUrls=false just before displaying this string, none of the other links are displayed as links. Is there a way to partially set DetectUrls for some strings and not for others? Thanks

  • Exclude subexpression from regex in c++

    - by wyatt
    Suppose I was trying to match the following expression using regex.h in C++, and trying to obtain the subexpressions contained: /^((1|2)|3) (1|2)$/ Suppose it were matched against the string "3 1", the subexpressions would be: "3 1" "3" "1" If, instead it were matched against the string "2 1", the subexpressions would be: "2 1" "2" "2" "1" Which means that, depending on how the first subexpression evaluates, the final one is in a different element in the pmatch array. I realise this particular example is trivial, as I could remove one of the sets of brackets, or grab the last element of the array, but it becomes problematic in more complicated expressions. Suppose all I want are the top-level subexpressions, the ones which aren't subexpressions of other subexpressions. Is there any way to only get them? Or, alternatively, to know how many subexpressions are matched within a subexpression, so that I can traverse the array irrespective of how it evaluates? Thanks
