  • StreamSocket to Stream in windows phone 8

    - by Abouzar Nouri
    I am trying to use Bluetooth in WP8 to send an image from my app on a device and show it in my app on another device. The receiver has a StreamSocket object to read the data from it like the code below await _dataReader.LoadAsync(4); uint messageLen = (uint)_dataReader.ReadInt32(); await _dataReader.LoadAsync(messageLen); string imageData _dataReader.ReadString(messageLen); Then I have to save all the received data (image) on the device and then create a Stream object from the stored data to give it to the BitmapSource.SetSource(Stream) function to be able to show this image on my app. var image = new BitmapImage(); image.SetSource(stream); All I want to do is not to skip this double work and directly convert the StreamSocket object (from Bluetooth connection) to a Stream object and make the BitmapSource image. Is there any way to do this?

  • How do I get class of an internal static class in another assembly?

    - by Echiban
    I have a class C in Assembly A like this: internal class C { internal static string About_Name { get { return "text"; } ... } I have about 20 such static properties. Is there a way, in an outside assembly, without using friend assembly attribute (.Net reflection only), get class C so I can invoke any of the static string properties like this: Class C = <some .Net reflection code>; string expected = C.About_Name; If that is not possible, a .Net reflection code to get the string property value directly will suffice, but not ideal. Thanks in advance!

  • best way to find out type

    - by laspal
    hi, I have a dict val_dict - {'val1': 'abcd', 'val': '1234', 'val3': '1234.00', 'val4': '1abcd 2gfff'} All the values to my keys are string. So my question is how to find out type for my values in the dict. I mean if i say`int(val_dict['val1']) will give me error. Basically what I am trying to do is find out if the string is actual string or int or float.` if int( val_dict['val1'): dosomething else if float(val_dict['val1']): dosomething thanks

  • How can I center a box of unknown width in CSS?

    - by NXTBoy
    I have this html: <div class="object-box"> <img ... /> <span class="caption">This is the caption</span> </div> Which is accompanied with this CSS: .object-box .caption, .object-box img { display: block; } .object-box { border: 1px solid; } I would like the surrounding div to shrink-wrap to its contents. I can achieve this by using float: ... or display: inline-block. However, I'd also like it to be centered on the page, using margin: auto. The two approaches don't seem to be compatible. Is it possible to create such a shrink-wrapped, centered container, without adding a wrapper element?

  • Case insensitive expectations in Rhino Mocks

    - by user313886
    I'm using Rhino Mocks to expect a call. There is a single parameter which is a string. But I'm not bothered about the case of the string. I want the test to pass even if the case is wrong. So I'm doing the following: //expect log message to be called with a string parameter. //We want to ignore case when verifiyig so we use a constraint instead of a direct parameter Expect.Call(delegate { logger.LogMessage(null); }).Constraints(Is.Matching<string>(x => x.ToLower()=="f2")); It seems a bit log winded. Is there a more sensible way of doing this?

  • Printing Two Dimensional Array in Special Format

    - by user554313
    Hello everybody, I am working in a small task that allow the user to enter the regions of any country and store them in one array. Also, each time he enters a region, the system will ask him to enter the neighbours of that entered region and store these neighbours. I did the whole task but I have a small problem: I could not be able to print each region and its neighbours like the following format: Region A: neighbour1 neighbour2 Region B: neighbour1 neighbour2 For example, let us take USA map. I want to print the result as following: Washington D.C: Texas, Florida, Oregon and so on. My code is: import java.io.*; import java.util.Arrays; import java.util.Scanner; public class Test7{public static void main(String[] args) { Scanner kb = new Scanner(System.in); System.out.print("Please enter the number of regions: "); int REGION_COUNT = kb.nextInt(); String[] regionNames = new String[REGION_COUNT]; String[][] regions = new String[REGION_COUNT][2]; for (int r = 0; r < regions.length; r++) { System.out.print("Please enter the name of region #" + (r + 1) + ": "); regionNames[r] = kb.next(); System.out .print("How many neighbors for region #" + (r + 1) + ": "); if (kb.hasNextInt()) { int size = kb.nextInt(); regions[r] = new String[size]; for (int n = 0; n < size; n++) { System.out.print("Please enter the neighbour #" + (n) + ": "); regions[r][n] = kb.next(); } } else System.exit(0); } for (int i = 0; i < REGION_COUNT; i++) { System.out.print(regionNames[i] +": "); for (int k = 0; k < 2; k++) { System.out.print(regions[i][k]+", "); } System.out.println(); } } }

  • When to retain a "delegate"

    - by Jose
    I know that in Objective-C you should never retain your delegates because it may cause a retain-cycle, however, how do you know the difference between a delegate and a non-delegate object ? Can't it be said that just sending a message to any object is delegating work to that object ?

  • XML parsing problem

    - by Albinoswordfish
    I'm having this strange XML parsing problem. I have this XML string I'm trying to parse <?xml version="1.0"?> <response status="success"> <lot>32342</lot> </response> I'm using XPath with Java in order to do this. I'm using the Xpath expression "/response/@status" to find the text "success". However whenever I evaluate this expression I get an empty string. However I am able to successfully parse this string using "/response/@type" <?xml version="1.0"?> <response type="success"> <lot>32342</lot> </response> So why would simply changing the name of the attribute change the return string to nothing? is = new InputSource(testWOcreateStrGood); xPathexpressionSuccess = xPath.compile("/response/@status"); responseStr = xPathexpressionSuccess.evaluate(is); reponseStr is the string I posted earlier with the "status" attribute

  • Setting pixel values in Nvidia NPP ImageCPU objects?

    - by solvingPuzzles
    In the Nvidia Performance Primitives (NPP) image processing examples in the CUDA SDK distribution, images are typically stored on the CPU as ImageCPU objects, and images are stored on the GPU as ImageNPP objects. boxFilterNPP.cpp is an example from the CUDA SDK that uses these ImageCPU and ImageNPP objects. When using a filter (convolution) function like nppiFilter, it makes sense to define a filter as an ImageCPU object. However, I see no clear way setting the values of an ImageCPU object. npp::ImageCPU_32f_C1 hostKernel(3,3); //allocate space for 3x3 convolution kernel //want to set hostKernel to [-1 0 1; -1 0 1; -1 0 1] hostKernel[0][0] = -1; //this doesn't compile hostKernel(0,0) = -1; //this doesn't compile hostKernel.at(0,0) = -1; //this doesn't compile How can I manually put values into an ImageCPU object? Notes: I didn't actually use nppiFilter in the code snippet; I'm just mentioning nppiFilter as a motivating example for writing values into an ImageCPU object. The boxFilterNPP.cpp example doesn't involve writing directly to an ImageCPU object, because nppiFilterBox is a special case of nppiFilter that uses a built-in gaussian smoothing filter (probably something like [1 1 1; 1 1 1; 1 1 1]).

  • How to stop attributes from being pickled in Python

    - by Ries
    I am using gnosis.xml.pickle to convert an object of my own class to xml. The object is initialized so that: self.logger = MyLogger() But when I do dump the object to a string I get an exception stating that the pickler encountered an unpickleable type . Is there a way to 'tag' the logger attribute so that pickler will know not to try and pickle that attribute?

  • databind a DropDownList control with a list of all sub directories that exist in a particular direct

    - by sushant
    I am wanting to databind a DropDownList control with a list of all sub directories that exist in a particular directory on the server. The directory I want to search is in the root of the application. I am fairly new to programming and I'm not sure where to even start. I found this code on a website: Dim root As String = "C;\" Dim folders() As String = Directory.GetDirectories(root) Dim sb As New StringBuilder(2048) Dim f As String For Each f In folders Dim foldername As String = Path.GetFileName(f) sb.Append("<option>") sb.Append(foldername) sb.Append("</option>") Next Label3.Text = "<select runat=""sever"" id=""folderlist""" & sb.ToString() & "</select>" I guess this is vb. but my tool is in asp, so is their something similar in vbscript so that I can use it.

  • C# Casting system.__comobject to class type

    - by ijrufus
    I have an Excel Add-In that I'm currently trying to set up a unit test framework for. For the unit tests I've followed this guide: http://blogs.msdn.com/b/varsha/archive/2010/08/17/writing-automated-test-cases-for-vsto-application.aspx It seems to work fine, until I want to return a class object from my interface. Specifying the class object as the return type throws a "return argument has an invalid type" exception when calling the method. Changing the return type from the class to an object allows me to call the method and get the object, but now I'm unable to cast it as the class and use it as intended, getting this exception message when I try: > Unable to cast COM object of type 'System.__ComObject' to class type > 'anaplan.Utility.XYCoordinates'. Instances of types that represent COM > components cannot be cast to types that do not represent COM > components; however they can be cast to interfaces as long as the > underlying COM component supports QueryInterface calls for the IID of > the interface. I've retrieved the Type name using VisualBasic.Information.TypeName and it's showing it as the class I expect. Is there any way to get the comobject cast back to the class? Or another way to access the properties it has? Or am I just being a bit stupid here?

  • Explain Entity Framework 4's connection strings

    - by metanaito
    I created an Entity Framework file. My database is called MyDB. My Entity Framework file is MyDB.edmx and I used an existing connection string (MyDBConnectionString) to generate the edmx model. It created two more connection strings: MyDBEntities MyDBContainer What are these for? They look exactly the same and both have the information from my old connection string. Do I still need my old connection string?

  • Method parameters confusion

    - by elec
    Often time methods take more than 3 parameters which are all of the same type, eg. void mymethod (String param1, String param2, String param3) then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2: mymethod (param2, param1, param3); ...which can be the cause of much time spent debugging what should be a trivial matter. Any tips on how to avoid this sort of mistake (apart from unit tests) ?

  • query on custom field via webservice

    - by Roberto Parrotto
    I customized the content of Defect in my Rally workspace adding a new custom field. This custom field is of type string, its name is CustomTest and its display name is CustomAttribute. I added the value "test" on a defect, but I can't create a working query on that custom field (I'm developing in Java and using the ws api for rally). the query I tried are String query8 = "(CustomAttribute = \"test\")"; String query9 = "(CustomAttribute = \"test\")";

  • Is it any loose coupling mechanism in Objective-C + Cocoa like C# delegates or C++Qt signals+slots?

    - by Eye of Hell
    Hello. For a large programs, the standard way to chalenge a complexity is to divide a program code into small objects. Most of the actual programming languages offer this functionality via classes, so is Objective-C. But after source code is separated into small object, the second challenge is to somehow connect them with each over. Standard approaches, supported by most languages are compositon (one object is a member field of another), inheritance, templates (generics) and callbacks. More cryptic techniques include method-level delagates (C#) and signals+slots (C++Qt). I like the delegates / signals idea, since while connecting two objects i can connect individual methods with each over, without objects knowing anything of each over. For C#, it will look like this: var object1 = new CObject1(); var object2 = new CObject2(); object1.SomethingHappened += object2.HandleSomething; In this code, is object1 calls it's SomethingHappened delegate (like a normal method call) the HandleSomething method of object2 will be called. For C++Qt, it will look like this: var object1 = new CObject1(); var object2 = new CObject2(); connect( object1, SIGNAL(SomethingHappened()), object2, SLOT(HandleSomething()) ); The result will be exactly the same. This technique has some advantages and disadvantages, but generally i like it more than interfaces since if program code base grows i can change connections and add new ones without creating tons of interfaces. After examination of Objective-C i havn't found any way to use this technique i like :(. It seems that Objective-C supports message passing perfectly well, but it requres for object1 to have a pointer to object2 in order to pass it a message. If some object needs to be connected to lots of other objects, in Objective-C i will be forced to give him pointers to each of the objects it must be connected. So, the question :). Is it any approach in Objective-C programming that will closely resemble delegate / signal+slot types of connection, not a 'give first object an entire pointer to second object so it can pass a message to it'. Method-level connections are a bit more preferable to me than object-level connection ^_^.

  • Mysql maven jpa skeleton

    Hi, is there a skeleton for a project using mysql, some eclipse/top link with RESOURCE_LOCAL as connection type? Preferably using maven. I'm searching for it for hours and can't get running even the sipmlest exaple. So if you had it ready and running, please, post :-). Even something as simple as these two classes only. @Entity public class Message implements Serializable{ public Message() {} public Message(String s){ this.s = s; } @Id String s; public String getS(){ return s; } } public class App { static private EntityManagerFactory emf; static private EntityManager em; public static void main( String[] args ) { emf = Persistence.createEntityManagerFactory("persistence"); em = emf.createEntityManager(); Message m = new Message("abc"); em.persist(m); } }

  • Qt and finding partial matches in a QList

    - by ExpatEgghead
    I have a struct viz: struct NameKey { std::string fullName; std::string probeName; std::string format; std::string source; } which are held in a QList: QList<NameKey> keyList; what I need to do is find an occurence in keyList of a partial match where the search is for a NameKey that only has two members filled. All the keyList entries are full NameKey's. My current implementation is , well, boring in the extreme with too many if's and conditions. So, If I have a DataKey with a fullName and a format I need to find all the occurences in keyList which match. Any useful Qt/boost things available?

  • C++ - getline() keeps reading the same line over and over again for some reason

    - by Jammanuser
    I am wondering WTF my while loop which calls istream& getline ( istream& is, string& str ); keeps reading the same line again. I have the following while loop (nested down several levels of other while loops and if statements) which calls getline, but my output statement which is the first code line in the while loop's block of code tells me it is reading the same line over and over again, which explains why my output file doesn't contain the right data when my program is finished. while (getline(file_handle, buffer_str)) { cout<< buffer_str <<endl; cin.get(); if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } else if (buffer_str.find(search_str6, 0) != string::npos) { //we're now at the second problem line of the first case buffer_str += " {\n"; output_str += buffer_str; output_str += '\n'; getline(file_handle, buffer_str); //We're now at the beginning of the 'exc' initialiation statement output_str += buffer_str; output_str += '\n'; while (getline(file_handle, buffer_str)) { if ((buffer_str.find(';', 0) != string::npos) && (buffer_str.find('\"', 0) != string::npos)) { //we're now at the end of the 'exc' initialiation statement buffer_str.erase(buffer_str.size() - 2, 1); buffer_str += '\n'; for (size_t i = 0; i < pos; i++) { buffer_str += ' '; } buffer_str += "throw(exc);\n"; for (size_t i = 0; i < (pos - 3); i++) { buffer_str += ' '; } buffer_str += '}'; } output_str += buffer_str; output_str += '\n'; if (buffer_str.find("return", 0) != string::npos) { getline(file_handle, buffer_str); output_str += buffer_str; output_str += '\n'; about_to_break = true; break; //out of this while loop } } } if (about_to_break) { break; //out of the level 3 while loop (execution then goes back up to beginning of level 2 while loop) } output_str += buffer_str; output_str += '\n'; } Because of this problem, my if statement and then my else statement in my loop are not functioning as they should, and it doesn't break out of that loop when it should (though it eventually does break out of it, but I don't know exactly how yet). Anyone have any idea what could be causing this problem?? Thanks in advance.
