  • how to convert byte array to image in java?

    - by nemade-vipin
    I am developing a Web application in Java. In that application, I have created webservices in Java. In that webservice, I have created one webmethod which returns the image list in base64 format. The return type of the method is Vector. In webservice tester I can see the SOAP response as xsi:type="xs:base64Binary". Then I called this webmethod in my application. I used the following code: SBTSWebService webService = null; List imageArray = null; List imageList = null; webService = new SBTSWebService(); imageArray = webService.getSBTSWebPort().getAddvertisementImage(); Iterator itr = imageArray.iterator(); while(itr.hasNext()) { String img = (String)itr.next(); byte[] bytearray = Base64.decode(img); BufferedImage imag=ImageIO.read(new ByteArrayInputStream(bytearray)); imageList.add(imag); } In this code I am receiving the error: java.lang.ClassCastException: [B cannot be cast to java.lang.String" on line String img = (String)itr.next(); Is there any mistake in my code? Or is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue? Note:- I already droped this question and I got the suggetion to try the following code Object next = iter.next(); System.out.println(next.getClass()) I tried this code and got the output as byte[] from webservice. but I am not able to convert this byte array to actual image. is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue?

  • Subsonic 3.0 - .Net - Error : Can not ceate an instance of an interface

    - by George
    Hi, I am new to Subsonic, I have configured Subsonic3.0 T4 Template and created classes for my project. I have taken GridView and Object Datasource. Object datasource will connect to the one of the classes which is created from subsonic. I have set object datasource for g\fetch, Insert, Update and delete methods. Then i set the datasource of grid witht he object datasource. Grid view successfully showing me all the records. But at the time of Update, Insert or delete it throws an exception that "Can not ceate an instance of an interface". And also i am not able to dwbug in the code of the subsonic. May be because of partial classes. Can anyone please let me know what is happening at the backgrund? Or may be one can give me sample example which contains subsonic 3.0 and grid add, edit and delete so it will be really helpful for me.... Please... :) Thanks, George

  • How can i zip files in Java and not include files paths

    - by Ignacio
    For example, i want to zip a file stored in /Users/me/Desktop/image.jpg I maded this method: public static Boolean generateZipFile(ArrayList<String> sourcesFilenames, String destinationDir, String zipFilename){ // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // VER SI HAY QUE CREAR EL ROOT PATH boolean result = (new File(destinationDir)).mkdirs(); String zipFullFilename = destinationDir + "/" + zipFilename ; System.out.println(result); // Create the ZIP file ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFullFilename)); // Compress the files for (String filename: sourcesFilenames) { FileInputStream in = new FileInputStream(filename); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filename)); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); return true; } catch (IOException e) { return false; } } But when i extract the file, the unzipped files have the full path. I don't want the full path of each file in the zip i only want the filename. How can i made this?

  • An Interactive Console I/O Wrapper/Interceptor in C# - What is the issue?

    - by amazedsaint
    I was trying to put together an interactive Console interceptor/wrapper in C# over the weekend, by re-mixing few code samples I've found in SO and other sites. With what I've as of now, I'm unable to read back from the console reliably. Any quick pointers? public class ConsoleInterceptor { Process _interProc; public event Action<string> OutputReceivedEvent; public ConsoleInterceptor() { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo("cmd"); InitializeInterpreter(); } public ConsoleInterceptor(string command) { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo(command); InitializeInterpreter(); } public Process InterProc { get { return _interProc; } } private void InitializeInterpreter() { InterProc.StartInfo.RedirectStandardInput = true; InterProc.StartInfo.RedirectStandardOutput = true; InterProc.StartInfo.RedirectStandardError = true; InterProc.StartInfo.CreateNoWindow = true; InterProc.StartInfo.UseShellExecute = false; InterProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; bool started = InterProc.Start(); Redirect(InterProc.StandardOutput); Redirect(InterProc.StandardError); } private void Redirect(StreamReader input) { new Thread((a) => { var buffer = new char[1]; while (true) { if (input.Read(buffer, 0, 1) > 0) OutputReceived(new string(buffer)); }; }).Start(); } private void OutputReceived(string text) { if (OutputReceivedEvent != null) OutputReceivedEvent(text); } public void Input(string input) { InterProc.StandardInput.WriteLine(input); InterProc.StandardInput.Flush(); } }

  • How to read and set a value of a specific cell in an ExtJS Grid ?

    - by Lou
    Hello, I am beginning with ExtJS. I am trying to read a value from a cell that is selected I use an EditorGrid and the store looking like that : my_store = new Ext.data.JsonStore({ root: 'topics', totalProperty: 'totalCount', idProperty: 'details_id', fields: [ {name : 'index', type : 'int'}, {name : 'inactive', type : 'int'}, {name : 'c_1', type : 'string'}, {name : 'c_2', type : 'string'}, {name : 'c_3', type : 'string'}, {name : 'c_4', type : 'string'} ], proxy: new Ext.data.ScriptTagProxy({ url: 'my_proxy_url' }) }); As of now, this is what I use to retrieve the rows and columns of the selected cell : var column = grid.getSelectionModel().selection.cell[0]; var row = grid.getSelectionModel().selection.cell[1]; How can I read the value of a selected cell in the grid and change this value ?

  • Setting generic type at runtime

    - by destroyer of evil
    I have a class public class A<T> { public static string B(T obj) { return TransformThisObjectToAString(obj); } } I can call the static function like this just fine on a known/specified type: string s= A<KnownType>.B(objectOfKnownType); How do I make this call, if I don't know T beforehand, rather I have a variable of type Type that holds the type. If I do this: Type t= typeof(string); string s= A<t>.B(someStringObject); I get this compiler error: Cannot implicitly convert type 't' to 'object'

  • Correct use of Classloader (especially in Android)

    - by Sebi
    I read some documentations about classloaders, but im still not sure where and why they are needed. The Android API says: Loads classes and resources from a repository. One or more class loaders are installed at runtime. These are consulted whenever the runtime system needs a specific class that is not yet available in-memory. So if i understand this correct, there can be many classlaoders which are responsible for loading new classes. But how the system decides which to use? And in which situation should a developer instantiate a new classloader? In the Android API for Intent there is a method public void setExtrasClassLoader (ClassLoader loader) The description says: Sets the ClassLoader that will be used when unmarshalling any Parcelable values from the extras of this Intent. So can i define there a special classloader so that i can pass object with an Intent which are not defined in the receiving activity? An example: If activity A which is located in Project A (in Eclipse) defines an object which i want to send to Activity B in Project B using putExtra of the Intent object. If this object which is send over the Intent is not defined (source code in project B), then there is a NoClassDefFoundException. So can i use the method setExtraClassloader to avoid this exception? If yes, how can i decide which classloader object i have to pass? And how do I instantiate it correctly?

  • What is the best way get and hold property reference by name in c#

    - by Jeff Weber
    I want to know if there is a better way (than what I'm currently doing) to obtain and hold a reference to a property in another object using only the object and property string names. Particularly, is there a better way to do this with the new dynamic functionality of .Net 4.0? Here is what I have right now. I have a "PropertyReference<T>" object that takes an object name and property name in the constructor. An Initialize() method uses reflection to find the object and property and stores the property Getter as an Action<T> and the property Setter as an Func<T>. When I want to actually call the property I do something like this: int x = _propertyReference.Get(); or _propertyReference.Set(2); Here is my PropertyReference<T> code. Please dissect and make suggestions for improvement. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; using System.Xml; namespace WindowsFormsApplication2 { public class PropertyReference<T> : IPropertyReference { public string ComponentName { get; set; } public string PropertyName { get; set; } public bool IsInitialized { get { return (_action != null && _func != null); } } Action<T> _action; Func<T> _func; public PropertyReference() { } public PropertyReference(string componentName, string propertyName) { ComponentName = componentName; PropertyName = propertyName; } public void Initialize(IEntity e) { Object component = e.GetByName(ComponentName); if (component == null) return; Type t = e.GetByName(ComponentName).GetType(); PropertyInfo pi = t.GetProperty(PropertyName); _action = (T a) => pi.SetValue(component, a, null); _func = () => (T)pi.GetValue(component, null); } public void Reset() { _action = null; _func = null; } public void Set(T value) { _action.Invoke(value); } public T Get() { return _func(); } } } Note: I can't use the "Emit" functionality as I need this code to work on the new Windows Phone 7 and that does not support Emit.

  • Access container page of a component in .net based CT

    - by Huston Lopes
    We are developing a .net based CT based on Broker query Mechanism (filter): ComponentPresentationAssembler cpAssembler = new ComponentPresentationAssembler(Page ID,Page object); In order to pass the page ID, I need to get the access of page on which the component is present. How can I access the page from package? Since this a CT, a component object would be available in page and not a page object. Tried the following piece of code, but without success: string pageURI = _package.GetValue("Page.ID"); Page objPage = (Page)_engine.GetSession().GetObject(pageURI); This is not working as there is no page object. What are the alternatives so that we can access the parent page of component from CT?

  • Why are virtual methods considered early bound?

    - by AspOnMyNet
    One definition of binding is that it is the act of replacing function names with memory addresses. a) Thus I assume early binding means function calls are replaced with memory addresses during compilation process, while with late binding this replacement happens during runtime? b) Why are virtual methods also considered early bound (thus the target method is found at compile time, and code is created that will call this method)? As far as I know, with virtual methods the call to actual method is resolved only during runtime and not compile time?! thanx EDIT: 1) A a=new A(); a.M(); As far as I know, it is not known at compile time where on the heap (thus at which memory address ) will instance a be created during runtime. Now, with early binding the function calls are replaced with memory addresses during compilation process. But how can compiler replace function call with memory address, if it doesn’t know where on the heap will object a be created during runtime ( here I’m assuming the address of method a.M will also be at same memory location as a )? 2) v-table calls are neither early nor late bound. Instead there's an offset into a table of function pointers. The offset is fixed at compile time, but which table the function pointer is chosen from depends on the runtime type of the object (the object contains a hidden pointer to its v-table), so the final function address is found at runtime. But assuming the object of type T is created via reflection ( thus app doesn’t even know of existence of type T ), then how can at compile time exist an entry point for that type of object?

  • Best practice for storage and retrieval of error messages.

    - by ferrari fan
    What is a best practice for storing user messages in a configuration file and then retrieving them for certain events throughout an application? I was thinking of having 1 single configuration file with entries such as REQUIRED_FIELD = {0} is a required field INVALID_FORMAT = The format for {0} is {1} etc. and then calling them from a class that would be something like this public class UIMessages { public static final String REQUIRED_FIELD = "REQUIRED_FIELD"; public static final String INVALID_FORMAT = "INVALID_FORMAT"; static { // load configuration file into a "Properties" object } public static String getMessage(String messageKey) { // return properties.getProperty(messageKey); } } Is this the right way to approach this problem or is there some de-facto standard already in place?

  • Passing array values in an HTTP request in .NET

    - by Zarjay
    What's the standard way of passing and processing an array in an HTTP request in .NET? I have a solution, but I don't know if it's the best approach. Here's my solution: <form action="myhandler.ashx" method="post"> <input type="checkbox" name="user" value="Aaron" /> <input type="checkbox" name="user" value="Bobby" /> <input type="checkbox" name="user" value="Jimmy" /> <input type="checkbox" name="user" value="Kelly" /> <input type="checkbox" name="user" value="Simon" /> <input type="checkbox" name="user" value="TJ" /> <input type="submit" value="Submit" /> </form> The ASHX handler receives the "user" parameter as a comma-delimited string. You can get the values easily by splitting the string: public void ProcessRequest(HttpContext context) { string[] users = context.Request.Form["user"].Split(','); } So, I already have an answer to my problem: assign multiple values to the same parameter name, assume the ASHX handler receives it as a comma-delimited string, and split the string. My question is whether or not this is how it's typically done in .NET. What's the standard practice for this? Is there a simpler way to grab the multiple values than assuming that the value is comma-delimited and calling Split() on it? Is this how arrays are typically passed in .NET, or is XML used instead? Does anyone have any insight on whether or not this is the best approach?

  • Delphi / MySql : Problems escaping strings

    - by mawg
    N00b here, having problems escaping strings. I used the QuotedStr() function - shouldn't that be enough. Unfortunately, the string that I am trying to quote is rather messy, but I will post it here in case anyone wants to paste it into WinMerge or KDiff3, etc. I am trying to store an entire Delphi form into the database, rather than into a .DFM file. It has only one field, a TEdit edit box.

  • Enabling/Disabling Aero from a Windows Service

    - by rgould
    I have some code to enable/disable the Windows Aero service in Vista, and I would like to run it in a Windows Service. The code works in a standalone application, but when I run it from a Service, nothing happens. No errors or exceptions are thrown. I realise that running code in a service is a different scope than running code in an application, but in this case, how would I enable/disable Aero from the service? Is this even possible? Here is the code I am working with: public static readonly uint DWM_EC_DISABLECOMPOSITION = 0; public static readonly uint DWM_EC_ENABLECOMPOSITION = 1; [DllImport("dwmapi.dll", EntryPoint="DwmEnableComposition")] protected static extern uint Win32DwmEnableComposition(uint uCompositionAction); public static bool EnableAero() { Win32DwmEnableComposition(DWM_EC_ENABLECOMPOSITION); } Edit: It turns out that the DwmEnableComposition call is returning HRESULT 0x80070018, or ERROR_BAD_LENGTH. Seems like a strange error, since the code works when not running as a service. I also tried changing the entire thing to the following code, but got the same result. It sets the window station and desktop, and it seems to be correct, but the call to DwmEnableComposition results in the same error. I've not included the PInvoke declarations for brevity. protected override void OnStop() { IntPtr winStation = OpenWindowStation("winsta0", true, 0x10000000 /* GENERIC_ALL */); if (winStation == null || winStation.ToInt32() == 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } if (!SetProcessWindowStation(winStation)) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } uint thread = GetCurrentThreadId(); IntPtr hdesk = OpenInputDesktop(0, false, 0x10000000 /* GENERIC_ALL */); if (hdesk == null || hdesk.ToInt32() == 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } if (!SetThreadDesktop(hdesk)) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } uint result = Win32DwmEnableComposition(DWM_EC_DISABLECOMPOSITION); if (result != 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } }

  • nhibernate fluent repository pattern insert problem

    - by voam
    I am trying to use Fluent NHibernate and the repository pattern. I would like my business layer to not be knowledgeable of the data persistence layer. Ideally I would pass in an initialized domain object to the insert method of the repository and all would be well. Where I run into problems is if the object being passed in has a child object. For example say I want to insert an a new order for a customer, and the customer is a property of the order object. I would like to do something like this: Customer c = new Customer; c.CustomerId = 1; Order o = new Order; o.Customer = c; repository.InsertOrder(o); The problem is that using NHiberate the CustomerId field is only privately settable so I can not set it directly like this. so what I have ended up doing is have my repository have an interface of Order InsertOrder(int customerId) where all the foreign keys get passed in as parameters. Somehow this just doesn't seem right. The other approach was to use the NHibernate session variable to load a customer object in my business model and then have the order passed in to the repository but this defeats my persistence ignorance ideal. Should I throw this persistence ignorance out the window or am I missing something here? Thanks

  • Can/Should you throw exceptions in a c# switch statement?

    - by Kettenbach
    Hi All, I have an insert query that returns an int. Based on that int I may wish to throw an exception. Is this appropriate to do within a switch statement? switch (result) { case D_USER_NOT_FOUND: throw new ClientException(string.Format("D User Name: {0} , was not found.", dTbx.Text)); case C_USER_NOT_FOUND: throw new ClientException(string.Format("C User Name: {0} , was not found.", cTbx.Text)); case D_USER_ALREADY_MAPPED: throw new ClientException(string.Format("D User Name: {0} , is already mapped.", dTbx.Text)); case C_USER_ALREADY_MAPPED: throw new ClientException(string.Format("C User Name: {0} , is already mapped.", cTbx.Text)); default: break; } I normally add break statements to switches but they will not be hit. Is this a bad design? Please share any opinions/suggestions with me. Thanks, ~ck in San Diego

  • SQL indexing on varchar

    - by alex
    I have a table whose columns are varchar(50) and a float - I need to (very quickly) look get the float associated with a given string. Even with indexing, this is rather slow. I know, however, that each string is associated with an integer, which I know at the time of lookup, so that each string maps to a unique integer, but each integer does not map to a unique string. One might think of it as a tree structure. Is there anything to be gained by adding this integer to the table, indexing on it, and using a query like SELECT floatval FROM mytable WHERE phrase=givenstring AND assoc=givenint? This is Postgres, and if you couldn't tell, I have very little experience with databases.

  • NSData release is not reclaiming memory

    - by ctpenrose
    iPhoneOS 3.2 I use NSKeyedUnarchiver's unarchiveObjectWithFile: to load a custom object that contains a single large NSData and another much smaller object. The dealloc method in my custom object gets called, the NSData object is released, its retainCount == 1 just before. Physical memory does not decrement by any amount, let alone a fraction of the NSData size, and with repetition memory warnings are reliably generated: I have test until I actually received level 2 warnings. =( NSString *archivePath = [[[NSBundle mainBundle] pathForResource:@"lingering"] ofType:@"data"] retain]; lingeringDataContainer = [[NSKeyedUnarchiver unarchiveObjectWithFile:archivePath] retain]; [archivePath release]; [lingeringDataContainer release]; and now the dealloc.... - (void) dealloc { [releasingObject release]; [lingeringData release]; [super dealloc]; } Before release: (gdb) p (int) [(NSData *) lingeringData retainCount] $1 = 1 After: (gdb) p (int) [(NSData *) lingeringData retainCount] Target does not respond to this message selector.
