  • ASP.NET file transfer from local machine to another machine

    - by Imcl
    I basically want to transfer a file from the client to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application. Using the link below, I wrote a code for my application. I am not able to get it right though, Please refer the link and help me ot with it... http://stackoverflow.com/questions/263518/c-uploading-files-to-file-server The following is my code:- protected void Button1_Click(object sender, EventArgs e) { filePath = FileUpload1.FileName; try { WebClient client = new WebClient(); NetworkCredential nc = new NetworkCredential(uName, password); Uri addy = new Uri("\\\\192.168.1.3\\upload\\"); client.Credentials = nc; byte[] arrReturn = client.UploadFile(addy, filePath); Console.WriteLine(arrReturn.ToString()); } catch (Exception ex) { Console.WriteLine(ex.Message); } } The following line doesn't execute... byte[] arrReturn = client.UploadFile(addy, filePath); This is the error I get: An exception occurred during a WebClient request

  • Asynchronous pages in the ASP.NET framework - where are the other threads and how is it reattached?

    - by rkrauter
    Sorry for this dumb question on Asynchronous operations. This is how I understand it. IIS has a limited set of worker threads waiting for requests. If one request is a long running operation, it will block that thread. This leads to fewer threads to serve requests. Way to fix this - use asynchronous pages. When a request comes in, the main worker thread is freed and this other thread is created in some other place. The main thread is thus able to serve other requests. When the request completes on this other thread, another thread is picked from the main thread pool and the response is sent back to the client. 1) Where are these other threads located? 2) IF ASP.NET likes creating new threads, why not increase the number of threads in the main worker pool - they are all running on the same machine anyway? 3) If the main thread hands off a request to this other thread, why does the request not get disconnected? It magically hands off the request to another worker thread somewhere else and when the long running process completes, it picks a thread from the main worker pool and sends response to the client. I am amazed...but how does that work?

  • C# average function without overflow exception

    - by Ron Klein
    .NET Framework 3.5. I'm trying to calculate the average of some pretty large numbers. For instance: using System; using System.Linq; class Program { static void Main(string[] args) { var items = new long[] { long.MaxValue - 100, long.MaxValue - 200, long.MaxValue - 300 }; try { var avg = items.Average(); Console.WriteLine(avg); } catch (OverflowException ex) { Console.WriteLine("can't calculate that!"); } Console.ReadLine(); } } Obviously, the mathematical result is 9223372036854775607 (long.MaxValue - 200), but I get an exception there. This is because the implementation (on my machine) to the Average extension method, as inspected by .NET Reflector is: public static double Average(this IEnumerable<long> source) { if (source == null) { throw Error.ArgumentNull("source"); } long num = 0L; long num2 = 0L; foreach (long num3 in source) { num += num3; num2 += 1L; } if (num2 <= 0L) { throw Error.NoElements(); } return (((double) num) / ((double) num2)); } I know I can use a BigInt library (yes, I know that it is included in .NET Framework 4.0, but I'm tied to 3.5). But I still wonder if there's a pretty straight forward implementation of calculating the average of integers without an external library. Do you happen to know about such implementation? Thanks!! UPDATE: The previous example, of three large integers, was just an example to illustrate the overflow issue. The question is about calculating an average of any set of numbers which might sum to a large number that exceeds the type's max value. Sorry about this confusion. I also changed the question's title to avoid additional confusion. Thanks all!!

  • PGP Encrypt from C# using GnuPG

    - by Kishore
    Hello All, I'm trying to encrypt a incoming document in C#, and I'm using GnuPG with input redirection. I need to use -se(sign and encrypt) in a single step, which requires entering passphrase. But for some reason, input redirection is not working. Appreciate your help. Control is going to else block. I'm not sure if there is deadlock or child process(gpg.exe) waiting for the input. pgpproc = new Process(); pgpproc.StartInfo.FileName = exeFilePath; pgpproc.StartInfo.RedirectStandardOutput = false; pgpproc.StartInfo.RedirectStandardInput = true; pgpproc.StartInfo.UseShellExecute = false; pgpproc.StartInfo.Arguments = "-a -o C:\PGPStaging\output.pgp -se -r recipientID C:\PGPStaging\input.txt"; pgpproc.StartInfo.CreateNoWindow = true; pgpproc.Start(); StreamWriter myStreamWriter = pgpproc.StandardInput; myStreamWriter.Write("*****"); myStreamWriter.Close(); if (pgpproc.WaitForExit(waittime)) { //success } else { //failure pgpproc.Kill(); pgpproc.WaitForExit(); } `

  • How to reproduce System.Security.Cryptography.SHA1Managed result in Python

    - by joetyson
    Here's the deal: I'm moving a .NET website to Python. I have a database with passwords hashed using the System.Security.Cryptography.SHA1Managed utility. I'm creating the hash in .NET with the following code: string hashedPassword = Cryptographer.CreateHash("MYHasher", userInfo.Password); The MYHasher block looks like this: <add algorithmType="System.Security.Cryptography.SHA1Managed, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=blahblahblah" saltEnabled="true" type="Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.HashAlgorithmProvider, Microsoft.Practices.EnterpriseLibrary.Security.Cryptography, Version=3.0.0.0, Culture=neutral, PublicKeyToken=daahblahdahdah" name="MYHasher" /> So for a given password, I get back and store in the database a 48 byte salted sha1. I assume the last 8 bytes are the salt. I have tried to reproduce the hashing process in python by doing a sha1(salt + password) and sha1(password + salt) but I'm having no luck. My question to you: How are the public keys being used? How is the password rehashed using the salt. How is the salt created? (e.g., When I say saltEnabled="true", what extra magic happens?) I need specific details that don't just reference other .NET libraries, I'm looking for the actual operational logic that happens in the blackbox. Thanks!

  • OutOfMemoryException, large Private Data

    - by Captain Comic
    Hello, In previous series: http://stackoverflow.com/questions/2543648/outofmemoryexception-stack-size-is-huge-large-number-of-threads I have a .net windows service that consumes a lot of memory. The GC heap is not big. Also the stack size is not big. What is big is something called a private data. Also I can see in task manager that my application consumes a lot something that taskmanager calls a handle. My application consumes 2326 handles. I believe that these handles are some windows handles that occupy private data. I can see that this private data is occupied by blocks marked as Thread Environment Block. What is that? Screenshot of my application memory usage by VMMap Screenshot of my application memory usage by Task Manager UPDATE I run ProcessExplorer. I have two instances of my service running at the moment. I can see that they consume a lot of virtual memory for Gen2 GC. This look suspicios. Also total reserved for GC Heap size is the same for two processes.

  • Fix common library functions, or abandon then?

    - by Ian Boyd
    Imagine i have a function with a bug in it: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } So the call: MakeLocation("Springfield", "MO"); would return "Springfield, MO" Now there's a slight problem, what if the user called: MakeLocation("Springfield, MO", "OH"); The called it wrong, obviously. But the function would return "Springfield, MO, OH". The system was functioning like this for many years, until i noticed the function being used wrong, and i corrected it. And i also updated the original function to catch such an obvious mistake - in case it's happening elsewhere: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } And testing showed the problem fixed. Except we missed an edge case, and the customer found it. So now the moral dillema. Do you ever add new sanity checks, safety checks, assertions to exising code? Or do you call the old function abandoned, and have a new one: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } Boolean MakeLocation2(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } The same can apply for anything: Question FetchQuestion(Int id) { if (id == 0) throw new EFetchQuestionException("No question ID specified"); ... } Do you risk breaking existing code, at the expense of existing code being wrong?

  • Is VB Really Case Insensitive?

    - by Otaku
    I'm not trying to start an argument here, but for whatever reason it's typically stated that VB is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is VB case insensitive? When I type... Dim ss As String Dim SS As String ...into the VS2008 IDE the second one has a warning of "Local variable 'SS' is already declared in the current block". In VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this argument that VB is not case sensitive? (Also, if you know or care to answer, why would that be a bad thing?) EDIT: Why am I even asking this question? I've used VB in many of it's dialects for years now, sometimes as a hobbyist, sometimes for small business-related programs in a workgroup. As of the last 6 months I've been working on a big project, much bigger than I anticipated. Much of the sample source code out there is in C#. I don't have any burning desire to learn C#, but if there are things I'm missing out on that C# offers that VB doesn't (an opposite would be VB.NET offers XML Literals), then I'd like to know more about that feature. So in this case, it's often argued that C languages are case sensitive and that's good and VB is case insensitive and that is bad. I'd like to know A) how exactly is VB case insensitive because every single example in the code editor becomes case sensititive (meaning case gets corrected) whether I want it or not and B) is this compelling enough for me to consider moving to C# if VB.NET case is somehow limiting what I could do with code?

  • jQuery.width() & DOM refresh

    - by o_O Tync
    My script dynamically creates a <ul> width left-floating <li>s inside: it's a paginator. Afterwards, the script measures width of all <li>s and summs them up. The problem is that after the nodes are injected into the document — the browser refreshed DOM and applies CSS styles which takes a while. It has a negative effect on my script: when these operations are not complete before I measure the width — my script gets a wrong value. If I perform the measure in a second — everything is ok. The thing I'm looking for is a way to detect the moment when the <ul> is fully drawn, styles applied and the width has stabilizes. Or at least a way to detect every dimensions changes. If there's a way to detect width stabilization — I would do the measuring right after it to get the correct values. P.S. Why I need this. My paginator's left-floating <li> items tend to move to the next line when the <ul> tries to become wider than the page itself. Even though most of <li>s are invisible because of parent <div>'s width restriction: div { width: 500px; overflow: hidden; } div ul { width: 100%; white-space: nowrap; } div ul li { display: block; float: left; } they still go down unless I specify the actual summed width of the <ul> with the script.

  • Data Driven MSTest: DataRow is always null

    - by David Back
    I am having a problem using Visual Studio data driven testing. I have tried to deconstruct this to the simplest example. I am using Visual Studio 2012. I create a new unit test project. I am referencing system data. My code looks like this: namespace UnitTestProject1 { [TestClass] public class UnitTest1 { [DeploymentItem(@"OrderService.csv")] [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "OrderService.csv", "OrderService#csv", DataAccessMethod.Sequential)] [TestMethod] public void TestMethod1() { try { Debug.WriteLine(TestContext.DataRow["ID"]); } catch (Exception ex) { Assert.Fail(); } } public TestContext TestContext { get; set; } } } I have a very small csv file that I have set the Build Options to to 'Content' and 'Copy Always'. I have added a .testsettings file to the solution, and set enable deployment, and added the csv file. I have tried this with and without |DataDirectory|, and with/without a full path specified (the same path that I get with Environment.CurrentDirectory). I've tried variations of "../" and "../../" just in case. Right now the csv is at the project root level, same as the .cs test code file. I have tried variations with xml as well as csv. TestContext is not null, but DataRow always is. I have not gotten this to work despite a lot of fiddling with it. I'm not sure what I'm doing wrong. Does mstest create a log anywhere that would tell me if it is failing to find the csv file, or what specific error might be causing DataRow to fail to populate? I have tried the following csv files: ID 1 2 3 4 and ID, Whatever 1,0 2,1 3,2 4,3 So far, no dice.

  • LoginView inside FormView control is not databinding on PostBack

    - by subkamran
    I have a fairly simple form: <asp:FormView> <EditItemTemplate> <asp:LoginView> <RoleGroups> <asp:RoleGroup roles="Blah"> <ContentTemplate> <!-- Databound Controls using Bind/Eval --> </ContentTemplate> </asp:RoleGroup> </RoleGroups> </asp:LoginView> <!-- Databound Controls --> </EditItemTemplate> </asp:FormView> <asp:LinqDataSource OnUpdating="MyDataSource_Updating" /> I handle my LinqDataSource OnUpdating event and do some work handling some M:N fields. That all works. However, once the update is finished (and I call e.Cancel = true), the LoginView control does not databind its children... so they are all blank. The FormView's viewstate is still fine, as all the rest of the controls outside of the LoginView appear fine. I even handle the FormView_DataBound event and a Trace shows that the FormView is being databound on postback. Why then is the LoginView not keeping its ViewState/being databound? Here's a sample code snippet showing the flow: protected void MyDataSource_Updating(object s, LinqDataSourceUpdateEventArgs e) { try { Controller.DoSomething(newData); // attempts to databind again here fail // frmView.DataBind(); // MyDataSource.DataBind(); // LoginView.DataBind(); } catch { // blah } finally { e.Cancel = true; } }

  • spring 3 AOP anotated advises

    - by Art79
    Trying to figure out how to Proxy my beans with AOP advices in annotated way. I have a simple class @Service public class RestSampleDao { @MonitorTimer public Collection<User> getUsers(){ .... return users; } } i have created custom annotation for monitoring execution time @Target({ ElementType.METHOD, ElementType.TYPE }) @Retention(RetentionPolicy.RUNTIME) public @interface MonitorTimer { } and advise to do some fake monitoring public class MonitorTimerAdvice implements MethodInterceptor { public Object invoke(MethodInvocation invocation) throws Throwable{ try { long start = System.currentTimeMillis(); Object retVal = invocation.proceed(); long end = System.currentTimeMillis(); long differenceMs = end - start; System.out.println("\ncall took " + differenceMs + " ms "); return retVal; } catch(Throwable t){ System.out.println("\nerror occured"); throw t; } } } now i can use it if i manually proxy the instance of dao like this AnnotationMatchingPointcut pc = new AnnotationMatchingPointcut(null, MonitorTimer.class); Advisor advisor = new DefaultPointcutAdvisor(pc, new MonitorTimerAdvice()); ProxyFactory pf = new ProxyFactory(); pf.setTarget( sampleDao ); pf.addAdvisor(advisor); RestSampleDao proxy = (RestSampleDao) pf.getProxy(); mv.addObject( proxy.getUsers() ); but how do i set it up in Spring so that my custom annotated methods would get proxied by this interceptor automatically? i would like to inject proxied samepleDao instead of real one. Can that be done without xml configurations? i think should be possible to just annotate methods i want to intercept and spring DI would proxy what is necessary. or do i have to use aspectj for that? would prefere simplest solution :- ) thanks a lot for help!

  • JEE6 Global JNDI Name and Maven Deployment

    - by wobblycogs
    I'm having some problems with the global JNDI names of my EJB resources which is (or at least will) cause my JNDI look ups to fail. The project is being developed on Netbeans and is a standard Maven Web Application. When my application is deployed to GF3.0 the application name is set to something like: com.example_myapp_war_1.0-SNAPSHOT which is all well and good from Netbeans point of view because it ensures the name is unique but it also means all the EJBs get global names such as this: java:global/com.example_myapp_war_1.0-SNAPSHOT/CustomerService This, of course, is going to cause problems because every time the version changes all the global names change (I've tested this by changing the version and the names indeed changed). The name is being generated from the POM file and it's a concatenation of: <groupId>com.example</groupId> <artifactId>myapp</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> Up until now I've got away with just injecting all the resources using @EJB but now I need to access the CustomerService EJB from a JSF Converter so I'm doing a JNDI look up like this: try { Context ctx = new InitialContext(); CustomerService customerService = (CustomerService)ctx.lookup( "java:global/com.example_myapp_war_1.0-SNAPSHOT/CustomerService" ); return customerService.get(submittedValue); } catch( Exception e ) { logger.error( "Failed to convert customer.", e ); return null; } which will clearly break when the application is properly released and the module name changes. So, the million dollar question: how can I set the modle name in maven or how do I recover the module name so that I can programatically build the JNDI name at runtile. I've tried setting it in the web.xml file as suggested by that link but it was ignored. I think I'd rather build the name at runtime as that means there is less scope for screw ups when the application is deployed. Many thanks for any help, I've been tearing my hair out all day on this.

  • Remove a hover class from a checkbox once clicked

    - by seangeraghty
    I am trying to remove a hover class applied to a checkbox via CSS once the box has been clicked. Does anyone know how to do this? JSFiddle http://jsfiddle.net/sa9fe/ The checkbox code is: <div> <input type="checkbox" id="checkbox-1-1" class="regular-checkbox flaticon-boxing3" /> <input type="checkbox" id="checkbox-1-2" class="regular-checkbox" /> <input type="checkbox" id="checkbox-1-3" class="regular-checkbox" /> <input type="checkbox" id="checkbox-1-4" class="regular-checkbox" /> </div> And the CSS for the checkbox are as follows: .regular-checkbox { vertical-align: middle; text-align: center; margin-left: auto; margin-right: auto; align: center; color: #39c; width: 140px; height: 140px; -webkit-border-radius: 6px; -moz-border-radius: 6px; border-radius: 6px; background-color: #fff; border: solid 1px #ccc; -webkit-appearance: none; background-color: #fff; display: inline-block; position: relative;} .regular-checkbox:checked { background-color: #39c; color: #fff !important;} .regular-checkbox:hover { background-color: #f0f7f9;} .regular-checkbox:checked:after { color: #fff; position: absolute; top: 0px; left: 3px; color: #99a1a7; } So any suggestions? Also does anyone know how to change the highlight because at the moment it seems to highlight the edges of the box at a border radius of 3px whereas the boxes I am using are 6px. Thanks Sean (newbie to coding)

  • SharePoint 2010 HttpModule problem

    - by Chris W
    I'm trying to write an HttpModule to run on our SharePoint farm - essentially it will check whether the user is authenticated and if they are it will validate some info against another database and potentially redirect the user to sign a variety of usage agreements. Whenever I enable the module in the web.config I'm finding that SharePoint has issues rendering the page - it's almost like the CSS is not getting loaded as the page is devoid of any styling. As a test I've even tried an empty module - i.e. an empty init block so it's not even hooking up any code to any events and the same issue arises. At this point it's an empty class that just implements IHttpModule so it's not even my dodgy coding causing the issue! The module is in a class library that I've dropped in to the bin folder of the application it needs to run against. In the web.config of the app I've simply added an entry as below: <modules runAllManagedModulesForAllRequests="true"> ... (default stuff ommitted) <add name="SharePointAUP" type="SPModules.SharePointAUP" /> </modules> I must be missing something really obvious here as I've done exactly the same as every sample I've found and yet I'm getting this strange behaviour. Is there something extra I need to do to get SharePoint to play nice with a custom module?

Any clues as to what causes this would be muchly appreciated! :-)

    Say i have an edit text and a button. In the edit text you would type a number and then when you hit the button it will either show the contact information or return with the name of that contact. I have tried all sorts of methods provided with no luck. The one i have successfully gotten the furthest with was the following... But i had no luck returning the name. Cursor phoneCursor = null; contactList = new HashMap<String,String>(); try{ Uri uContactsUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; String strProjection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME; phoneCursor = getContentResolver().query(uContactsUri, null, null, null, strProjection); phoneCursor.moveToFirst(); String name = ""; String phoneNumber = ""; int nameColumn = phoneCursor.getColumnIndex(Phone.DISPLAY_NAME); int phoneColumn = phoneCursor.getColumnIndex(Phone.NUMBER); phoneCursor.moveToNext(); } } catch(Exception e){ Log.e("[SmsMain] getContactData", e.toString()); } finally{ if(phoneCursor != null){ phoneCursor.close(); phoneCursor = null; } } }

  • C# Interop with dll

    - by Jim Jones
    Using VS2008 C# am attempting to interop a C++ dll. Have a C++ class constructor: make_summarizer(const char* rdir, const char* lic, const char* key); Need to retain a reference to the object that is created so I can use it in a follow-on function. When I did this in JNI the c code was: declare a static pointer to the object: static summarizer* summrzr; Then in one of the functions I called this constructor as follows: summrzr = make_summarizer(crdir, clic, ckey); Where the parameters all where the requisite const char* type; So in C# using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; using System.Configuration; namespace SummarizerApp { class SummApp { private IntPtr summarzr; public SummApp() { string resource_dir = ConfigurationManager.AppSettings["resource_dir"]; string license = ConfigurationManager.AppSettings["license"]; string key = ConfigurationManager.AppSettings["key"]; createSummarizer(resource_dir, license, key); } [System.Runtime.InteropServices.DllImportAttribute("lib\\summarizer37.dll", EntryPoint = "#1")] public static extern IntPtr make_summarizer( [InAttribute()][MarshalAsAttribute(UnmanagedType.LPTStr)] string rdir, [InAttribute()][MarshalAsAttribute(UnmanagedType.LPTStr)] string lic, [InAttribute()][MarshalAsAttribute(UnmanagedType.LPTStr)] string key); public void createSummarizer(string resource_dir, string license, string key) { try { this.summarzr = make_summarizer(resource_dir, license, key); } catch (AccessViolationException e) { Console.WriteLine(e.Message); Console.WriteLine(e.StackTrace); } } Have also tried using IntPtr created using Marshal.StringToHGlobalAnsi(string). Regardless I get a AccessViolationException on the line where I call the native constructor; So what am I doing wrong? Jim

  • Dojo addOnLoad, but is Dojo loaded?

    - by adamrice32
    I've encountered what seems like a chicken & egg problem, and have what I think is a logical solution. However, it occurred to me that others must have encountered something similar, so I figured I'd float it out there for the masses. The situation is that I want to use dojo's addOnLoad function to queue up a number of callbacks which should be executed after the DOM has completed rendering on the client side. So what I'm doing is as follows: <html> <head> <script type="text/javascript" src="dojo.xd.js"></script> ... </head> <body> ... <script type="text/javascript"> dojo.addOnLoad( ... ); dojo.addOnLoad( ... ); ... </script> </body> </html> Now, the issue is that I seem to be calling dojo.addOnLoad before the entire Dojo library has been downloaded the browser. This makes sense in a way, because the inline SCRIPT contents should be executed before the entire DOM is loaded (and the normal body onload callback is triggered). My question is this - is my approach sound, or would it make more sense to register a normal/standard body onload JavaScript callback to call a function, which does the same work that each of the dojo.addOnLoads is doing in the SCRIPT block. Of course, this begs the question, why would you ever then use dojo.addOnLoad if you're not guaranteed that the Dojo library will be loaded prior to using the library? Hopefully this situation makes sense to someone other than me. Seems like someone else may have encountered this situation. Thoughts? Best Regards, Adam Rice

  • part of contact are repeated after each writing the same contact (Android 2.0+)

    - by Bogus
    Hello, I met this problem at writing contacts by API for Android 2.0 or greater. Each time I write the same contact which already exist in my account (Google account) I got some part of contact aggregated ok but other did not. For example fields like FN, N, ORG, TITLE always are in one copy but TEL, EMAIL, ADR are added extra so after 2nd writing the same contact I have 2 copy the same TEL or EMAIL. How to force API engine to not repeate existed data ? Code: ArrayList ops = new ArrayList(); ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI) .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, accountType) .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, accountName) .build()); ... // adding phone number ContentProviderOperation.Builder builder = ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI); builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0); builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, phoneValue); builder.withValue(ContactsContract.CommonDataKinds.Phone.TYPE, phoneType); // work/home builder.withValue(ContactsContract.CommonDataKinds.Phone.LABEL, phoneLabel); ops.add(builder.build()); ... try { contentResolver.applyBatch(ContactsContract.AUTHORITY, ops); } catch (Exception e) { // } I tried add: AGGREGATION_MODE on AGGREGATION_MODE_DISABLED. but it changed nothing. I will glad for any hint in this case. BR, Bogus

    - by Hectai
    Hey! My code is below, and the problem is that some of the emails i get from my POP3 account cannot be read, but with a simple unix email client it can be. It would be very helpful if you can find me what the problem is, or give me some advices. ps.: yes, i have read the tutorials already. String[] messageText = new String[500]; Store store = session.getStore("pop3"); store.connect(host, username, password); Folder inbox = store.getFolder("INBOX"); inbox.open(Folder.READ_ONLY); Message[] messages = inbox.getMessages(); for(int i = 0; i < inbox.getMessageCount() ; i++) { Message m = messages[i]; Object o = m.getContent(); if (o instanceof String) messageText[i] = (String)o; else if(o instanceof Multipart) { Multipart mp = (Multipart)o; int count = mp.getCount(); for(int j = 0; j < count; j++) { BodyPart b = mp.getBodyPart(j); String disposition = b.getDisposition(); if (disposition != null && disposition.equals(BodyPart.ATTACHMENT))) { DataHandler handler = b.getDataHandler(); messageText[i] += "file name : " + handler.getName(); } else { messageText[i] += b.getContent(); } } } } store.close(); } catch(Exception ex) { notif("Failure - " + ex.getMessage()); }
