  • What precautions should you take when a senior employee leaves?

    - by Mahin
    EDIT : I agree one should check the reasons, why a senior level employee is leaving. But I am interested in knowing the official/management/technical/legal steps one should take after its decided that he is leaving, so that the life after him is smooth. What are the steps management should take when a senior programmer/team lead leaves your company. Some of them which I have thought about are : 1) If He used to manage hosting and domains stuff, change passwords of domain control panels and hosting panels. 2) If your published web sites have maintenance account and he is aware of credentials of that account then change this details also. 3) Suspend mail account for some time and forward all eMails of that account to some ex-employee account. After some time close that account. What are the other things one should check. I am expecting the answer to be a general check list one should follow. It should include both technical scenarios and management scenarios. Notable Suggestions so far : Effectively transfer the responsibilities of that employee to another one without causing any potential delay in your work. Protect your source code. If possible Make them to sign something to say that they don't have copies of source code.. You can also consider NDA here. Use the Notice Period to train his replacement. Now any new code to the project will be done by replacement with the help of Guy who is leaving. Ask him to create a document of things he thinks you should know. Make sure he checks everything in now and then any checkout will only be done by the replacement. Emails, copy off his email account to a pst.file (this assumes Outlook), Make this file available to his replacement. the employee should probably be given a chance to scrub the email. if you are going to keep his account open for whatever reason, check that no rules are created that forward incoming emails to an alternate address. Copy the hard drive of his computer to a network location and have someone senior go through and see if there are any files (drafts of performance reviews or other sensitive issues ) on it that someone else might need. Clearance from Accounts,Finance,Security,Library etc departments.Obtain all company property, laptops, keys, etc. If there is no reason not to, you should reward a departing person for their many years of service. Write them letters of recommendation (even if they already have a new job lined up).Say goodbye, and keep the door open. Make sure any outside clients know that the departing employee is not their main contact anymore. Never neglect the exit interview/debriefing. Confirm the last day of employment so that there is no misunderstanding Inform H/R if the employee is on H1B status, there is paperwork required to notify the government when an H1B employee leaves. Depending on how senior / what position, you might spend some time convincing him not to take the rest of the engineering staff with him. Make sure he spends his last days on a good note, because if he is not leaving on a good note, he can easily pollute the mind of his colleagues. Best Regards, Mahin Gupta EDIT : Now offered a bounty on it to get more detailed responses and practical suggestions.

  • Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

    - by Jakub Holý
    Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

  • Issue with Silverlight interop with JBoss WebService

    - by Hadi Eskandari
    I have a simple JAXWS webservice deployed in JBoss. It runs fine with a java client but I'm trying to connect using a Silverlight 3.0 application. I've changed the webservice to use Soap 1.1: @BindingType(value = "http://schemas.xmlsoap.org/wsdl/soap/http") public class UserSessionBean implements UserSessionRemote { ... } I'm using BasicHttpBinding on the Silverlight client. There are two issues: 1- When I connect from VisualStudio (2008 and 2010) to create the webservice proxies, the following exception is thrown, but the proxy is generated successfully. This also happens when I try to update the existing web service reference (but it also updates fine). com.sun.xml.ws.server.UnsupportedMediaException: Unsupported Content-Type: application/soap+xml; charset=utf-8 Supported ones are: [text/xml] at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:291) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:128) at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:287) at com.sun.xml.ws.transport.http.HttpAdapter.decodePacket(HttpAdapter.java:276) at com.sun.xml.ws.transport.http.HttpAdapter.access$500(HttpAdapter.java:93) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:432) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.servlet.ServletAdapter.handle(ServletAdapter.java:135) at org.jboss.wsf.stack.metro.RequestHandlerImpl.doPost(RequestHandlerImpl.java:225) at org.jboss.wsf.stack.metro.RequestHandlerImpl.handleHttpRequest(RequestHandlerImpl.java:82) at org.jboss.wsf.common.servlet.AbstractEndpointServlet.service(AbstractEndpointServlet.java:85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) 2- When I use the proxy to fetch some data from the webservice (even methods with primitive types), I get the following error on Silverlight client: "An error occurred while trying to make a request to URI 'http://localhost:9090/admintool/UserSessionEJB'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details." Setting a breakpoint on my java code, I can see that it is not hit when I run the silverlight client, so it is probably a cross domain issue, but I'm not sure how to handle it (I've already created a crossdomain.xml file and put it beside my HTML page hosting the silverlight client). I appreciate any help!

  • multiple-inheritance substitution

    - by Luigi
    I want to write a module (framework specific), that would wrap and extend Facebook PHP-sdk (https://github.com/facebook/php-sdk/). My problem is - how to organize classes, in a nice way. So getting into details - Facebook PHP-sdk consists of two classes: BaseFacebook - abstract class with all the stuff sdk does Facebook - extends BaseFacebook, and implements parent abstract persistance-related methods with default session usage Now I have some functionality to add: Facebook class substitution, integrated with framework session class shorthand methods, that run api calls, I use mostly (through BaseFacebook::api()), authorization methods, so i don't have to rewrite this logic every time, configuration, sucked up from framework classes, insted of passed as params caching, integrated with framework cache module I know something has gone very wrong, because I have too much inheritance that doesn't look very normal.Wrapping everything in one "complex extension" class also seems too much. I think I should have few working togheter classes - but i get into problems like: if cache class doesn't really extend and override BaseFacebook::api() method - shorthand and authentication classes won't be able to use the caching. Maybe some kind of a pattern would be right in here? How would you organize these classes and their dependencies? EDIT 04.07.2012 Bits of code, related to the topic: This is how the base class of Facebook PHP-sdk: abstract class BaseFacebook { // ... some methods public function api(/* polymorphic */) { // ... method, that makes api calls } public function getUser() { // ... tries to get user id from session } // ... other methods abstract protected function setPersistentData($key, $value); abstract protected function getPersistentData($key, $default = false); // ... few more abstract methods } Normaly Facebook class extends it, and impelements those abstract methods. I replaced it with my substitude - Facebook_Session class: class Facebook_Session extends BaseFacebook { protected function setPersistentData($key, $value) { // ... method body } protected function getPersistentData($key, $default = false) { // ... method body } // ... implementation of other abstract functions from BaseFacebook } Ok, then I extend this more with shorthand methods and configuration variables: class Facebook_Custom extends Facebook_Session { public funtion __construct() { // ... call parent's constructor with parameters from framework config } public function api_batch() { // ... a wrapper for parent's api() method return $this->api('/?batch=' . json_encode($calls), 'POST'); } public function redirect_to_auth_dialog() { // method body } // ... more methods like this, for common queries / authorization } I'm not sure, if this isn't too much for a single class ( authorization / shorthand methods / configuration). Then there comes another extending layer - cache: class Facebook_Cache extends Facebook_Custom { public function api() { $cache_file_identifier = $this->getUser(); if(/* cache_file_identifier is not null and found a valid file with cached query result */) { // return the result } else { try { // call Facebook_Custom::api, cache and return the result } catch(FacebookApiException $e) { // if Access Token is expired force refreshing it parent::redirect_to_auth_dialog(); } } } // .. some other stuff related to caching } Now this pretty much works. New instance of Facebook_Cache gives me all the functionality. Shorthand methods from Facebook_Custom use caching, because Facebook_Cache overwrited api() method. But here is what is bothering me: I think it's too much inheritance. It's all very tight coupled - like look how i had to specify 'Facebook_Custom::api' instead of 'parent:api', to avoid api() method loop on Facebook_Cache class extending. Overall mess and ugliness. So again, this works but I'm just asking about patterns / ways of doing this in a cleaner and smarter way.

  • MVVM, ContextMenus and binding to ViewModel defined Command

    - by Simon Fox
    Hi I am having problems with the binding of a ContextMenu command to an ICommand property in my ViewModel. The binding seems to be attaching fine...i.e when I inspect the value of the ICommand property it is bound to an instance of RelayCommand. The CanExecute delegate does get invoked, however when I open the context menu and select an item the Execute delegate does not get invoked. Heres my View (which is defined as the DataTemplate to use for instances of the following ViewModel in a resource dictionary): <UserControl x:Class="SmartSystems.DragDropProto.ProductLinkView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Proto"> <UserControl.Resources> <local:CenteringConverter x:Key="centeringConvertor"> </local:CenteringConverter> </UserControl.Resources> <UserControl.ContextMenu> <ContextMenu> <MenuItem Command="{Binding ChangeColor}">Change Color</MenuItem> </ContextMenu> </UserControl.ContextMenu> <Canvas> <Ellipse Width="5" Height="5" > <Ellipse.Fill> <SolidColorBrush Color="{Binding LinkColor}"></SolidColorBrush> </Ellipse.Fill> <Ellipse.RenderTransform> <TranslateTransform X="{Binding EndpointOneXPos, Converter={StaticResource centeringConvertor}}" Y="{Binding EndpointOneYPos, Converter={StaticResource centeringConvertor}}"/> </Ellipse.RenderTransform> </Ellipse> <Line X1="{Binding Path=EndpointOneXPos}" Y1="{Binding Path=EndpointOneYPos}" X2="{Binding Path=EndpointTwoXPos}" Y2="{Binding Path=EndpointTwoYPos}"> <Line.Stroke> <SolidColorBrush Color="{Binding LinkColor}"></SolidColorBrush> </Line.Stroke> </Line> <Ellipse Width="5" Height="5" > <Ellipse.Fill> <SolidColorBrush Color="{Binding LinkColor}"></SolidColorBrush> </Ellipse.Fill> <Ellipse.RenderTransform> <TranslateTransform X="{Binding EndpointTwoXPos, Converter={StaticResource centeringConvertor}}" Y="{Binding EndpointTwoYPos, Converter={StaticResource centeringConvertor}}"/> </Ellipse.RenderTransform> </Ellipse> </Canvas> </UserControl> and ViewModel (with uneccessary implementation details removed): class ProductLinkViewModel : BaseViewModel { public ICommand ChangeColor { get; private set; } public Color LinkColor { get; private set; } public ProductLinkViewModel(....) { ...

  • zLib on iPhone, stop at first BLOCK

    - by cedric
    I am trying to call iPhone zLib to decompress the zlib stream from our HTTP based server, but the code always stop after finishing the first zlib block. Obviously, iPhone SDK is using the standard open Zlib. My doubt is that the parameter for inflateInit2 is not appropriate here. I spent lots of time reading the zlib manual, but it isn't that helpful. Here is the details, your help is appreciated. (1) the HTTP request: NSURL *url = [NSURL URLWithString:@"http://192.168.0.98:82/WIC?query=getcontacts&PIN=12345678&compression=Y"]; (2) The data I get from server is something like this (if decompressed). The stream was compressed by C# zlib class DeflateStream: $REC_TYPE=SYS Status=OK Message=OK SetID= IsLast=Y StartIndex=0 LastIndex=6 EOR ...... $REC_TYPE=CONTACTSDISTLIST ID=2 Name=CTU+L%2EA%2E OnCallEnabled=Y OnCallMinUsers=1 OnCallEditRight= OnCallEditDLRight=D Fields= CL= OnCallStatus= EOR (3) However, I will only get the first Block. The code for decompression on iPhone (copied from a code piece from somewhere here) is as follow. The loop between Line 23~38 always break the second time execution. + (NSData *) uncompress: (NSData*) data { 1 if ([data length] == 0) return nil; 2 NSInteger length = [data length]; 3 unsigned full_length = length; 4 unsigned half_length =length/ 2; 5 NSMutableData *decompressed = [NSMutableData dataWithLength: 5*full_length + half_length]; 6 BOOL done = NO; 7 int status; 8 z_stream strm; 9 length=length-4; 10 void* bytes= malloc(length); 11 NSRange range; 12 range.location=4; 13 range.length=length; 14 [data getBytes: bytes range: range]; 15 strm.next_in = bytes; 16 strm.avail_in = length; 17 strm.total_out = 0; 18 strm.zalloc = Z_NULL; 19 strm.zfree = Z_NULL; 20 strm.data_type= Z_BINARY; 21 // if (inflateInit(&strm) != Z_OK) return nil; 22 if (inflateInit2(&strm, (-15)) != Z_OK) return nil; //It won't work if change -15 to positive numbers. 23 while (!done) 24 { 25 // Make sure we have enough room and reset the lengths. 26 if (strm.total_out >= [decompressed length]) 27 [decompressed increaseLengthBy: half_length]; 28 strm.next_out = [decompressed mutableBytes] + strm.total_out; 29 strm.avail_out = [decompressed length] - strm.total_out; 30 31 // Inflate another chunk. 32 status = inflate (&strm, Z_SYNC_FLUSH); //Z_SYNC_FLUSH-->Z_BLOCK, won't work either 33 if (status == Z_STREAM_END){ 34 35 done = YES; 36 } 37 else if (status != Z_OK) break; 38 } 39 if (inflateEnd (&strm) != Z_OK) return nil; 40 // Set real length. 41 if (done) 42 { 43 [decompressed setLength: strm.total_out]; 44 return [NSData dataWithData: decompressed]; 45 } 46 else return nil; 47 }

  • Calling webservice from WCF service

    - by Balaji
    I am having an issue consuming a webservice (c#.net) from a WCF service. The error i am getting is EndPointNotFoundException "TCP error code 10061: No connection could be made because the target machine actively refused it" I wrote a unit test to check if i could send a request to the web service and it worked fine [The unit test is using the same binding configuration as my WCF service] The web service and WCF service (client) have basichttp binding. Did anyone had similar kind of issue calling a webservice from a WCF service? The service Model section is as follows <system.serviceModel> <bindings> <basicHttpBinding> <binding name="DataService" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> <message clientCredentialType="UserName" algorithmSuite="Default"/> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://10.22.33.67/Service/DataService.asmx" binding="basicHttpBinding" bindingConfiguration="DataService" contract="Service.DataService" name="DataService"/> </client> <services> <service name="TestToConsumeDataService.WCFHost.Service1" behaviorConfiguration="TestToConsumeDataService.WCFHost.Service1Behavior"> <!-- Service Endpoints --> <endpoint address="" binding="basicHttpBinding" contract="TestToConsumeDataService.WCFHost.IService1"> <!-- Upon deployment, the following identity element should be removed or replaced to reflect the identity under which the deployed service runs.

  • How to bind dropdownlist data to complex class?

    - by chobo2
    Hi I am using asp.net mvc 2.0(default binding model) and I have this problem. I have a strongly typed view that has a dropdownlist <%= Html.DropDownList("List", "-----")%> Now I have a model class like Public class Test() { public List { get; set; } public string Selected {get; set;} } Now I have in my controller this public ActionResult TestAction() { Test ViewModel = new Test(); ViewModel.List = new SelectList(GetList(), "value", "text", "selected"); return View(Test); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult TestAction(Test ViewModel) { return View(); } Now when I load up the TestAction page for the first time it populates the dropdown list as expected. Now I want to post the selected value back to the server(the dropdownlist is within a form tag with some other textboxes). So I am trying to bind it automatically when it comes in as seen (Test ViewModel) However I get this big nasty error. Server Error in '/' Application.

  • What is my HttpContext.GetLocalResourceObject Method Virtual Path?

    - by ARUNRAJ
    I have read http://msdn.microsoft.com/en-us/library/ms149953.aspx and need to verify what is my GetLocalResourceObject virtual path. My local resource files are located on my pc at: C:\inetpub\wwwroot\GlobalX\Input\App_LocalResources Within this folder are my resource files for all the languages that site handles (InputContactDetails.aspx.ro.resx, InputContactDetails.aspx.hi.resx, etc.), as well as the default resource file (InputContactDetails.aspx.resx). I am receiving an error when I attempt to implement the virtual path string. Below is my line of offending code: return '<%= HttpContext.GetLocalResourceObject("~/GlobalX/Input/App_LocalResources/InputContactDetails.aspx.resx", "ContactDetails.Text", new System.Globalization.CultureInfo("ro")) %>'; I have tried ~/GlobalX/Input/App_LocalResources as the virtual path, and several other permutations, but I get the same error.

  • Android: OutOfMemoryError while uploading video - how best to chunk?

    - by AP257
    Hi all, I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code: // get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString); public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = readBytes(is); is.close(); return b3; } public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); // this is storage overwritten on each iteration with bytes int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); } And here's the traceback (the error is thrown on the byteBuffer.write(buffer, 0, len) line): 04-08 11:56:20.456: ERROR/dalvikvm-heap(6088): Out of memory on a 16775184-byte allocation. 04-08 11:56:20.456: INFO/dalvikvm(6088): "IntentService[UploadService]" prio=5 tid=17 RUNNABLE 04-08 11:56:20.456: INFO/dalvikvm(6088): | group="main" sCount=0 dsCount=0 s=N obj=0x449a3cf0 self=0x38d410 04-08 11:56:20.456: INFO/dalvikvm(6088): | sysTid=6119 nice=0 sched=0/0 cgrp=default handle=4010416 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:~93) 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.467: WARN/dalvikvm(6088): threadid=17: thread exiting with uncaught exception (group=0x4001b180) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): Uncaught handler: thread IntentService[UploadService] exiting due to uncaught exception 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): java.lang.OutOfMemoryError 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:93) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.496: INFO/Process(4657): Sending signal. PID: 6088 SIG: 3 I guess that as @DroidIn suggests, I need to upload it in chunks. But (newbie question alert) does that mean that I should make multiple PostMethod requests, and glue the file together at the server end? Or can I load the bytestream into memory in chunks, and glue it together in the Android code? If anyone could give me a clue as to the best approach, I would be very grateful.

  • IErrorHandler doesn't seem to be handling my errors in WCF .. any ideas?

    - by John Nicholas
    Have been readign around on IErrorHandler and want to go the config route. so, I have read the following in an attempt to implement it. MSDN Keyvan Nayyeri blog about the type defintion Rory Primrose Blog I have got it to compile and from the various errors i have fixed it seems like WCF is actually loading the error handler. My problem is that the exception that i am throwing to handle in the error handler doesn;t get the exception passed to it. My service implementation simply calls a method on another class that throws ArgumentOutOfRangeException - however this exception never gets handled by the handler. My web.config <system.serviceModel> <bindings> <basicHttpBinding> <binding name="basic"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <extensions> <behaviorExtensions> <add name="customHttpBehavior" type="ErrorHandlerTest.ErrorHandlerElement, ErrorHandlerTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <behaviors> <serviceBehaviors> <behavior name="exceptionHandlerBehaviour"> <serviceMetadata httpGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

  • How can I read the verbose output from a Cmdlet in C# using Exchange Powershell

    - by mrkeith
    Environment: Exchange 2007 sp3 (2003 sp2 mixed mode) Visual Studio 2008, .Net 3.5 Hello, I'm working with an Exchange powershell move-mailbox cmdlet and have noted when I do so from the Exchange Management shell (using the Verbose switch) there is a ton of real-time information provided. To provide a little context, I'm attempting to create a UI application that moves mailboxes similarly to the Exchange Management Console but desire to support an input file and specific server/database destinations for each entry (and threading). Here's roughly what I have at present but I'm not sure if there is an event I need to register for or what... And to be clear, I desire to get this information in real-time so I may update my UI to reflect what's occurring in the move sequence for the appropriate user (pretty much like the native functionality offered in the Management Console). And in case you are wondering, the reason why I'm not content with the Management Console functionality is, I have an algorithm which I'm using to balance users depending on storage limit, Blackberry use, journaling, exception mailbox size etc which demands user be mapped to specific locations... and I do not desire to create many/several move groups for each common destination or to hunt for lists of users individually through the management console UI. I can not seem to find any good documentation or examples of how to tie into reading the verbose messages that are provided within the console using C# (I see value in being able to read this kind of information in many different scenarios). I've explored the Invoke and InvokeAsync methods and the StateChanged & DataReady events but none of these seem to provide the information (verbose comments) that I'm after. Any direction or examples that can be provided will be very appreciated! A code sample which is little more than how I would ordinarily call any other powershell command follows: // config to use ExMgmt shell, create runspace and open it RunspaceConfiguration rsConfig = RunspaceConfiguration.Create(); PSSnapInException snapInException = null; PSSnapInInfo info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapInException); if (snapInException != null) throw snapInException; Runspace runspace = RunspaceFactory.CreateRunspace(rsConfig); try { runspace.Open(); // create a pipeline and feed script text Pipeline pipeline = runspace.CreatePipeline(); string targetDatabase = @"myServer\myStorageGroup\myDB"; string mbxOwner = "[email protected]"; Command myMoveMailbox = new Command("Move-Mailbox", false, false); myMoveMailbox.Parameters.Add("Identity", mbxOwner); myMoveMailbox.Parameters.Add("TargetDatabase", targetDatabase); myMoveMailbox.Parameters.Add("Verbose"); myMoveMailbox.Parameters.Add("ValidateOnly"); myMoveMailbox.Parameters.Add("Confirm", false); pipeline.Commands.Add(myMoveMailbox); System.Collections.ObjectModel.Collection output = null; // these next few lines that are commented out are where I've tried // registering for events and calling asynchronously but this doesn't // seem to get me anywhere closer // //pipeline.StateChanged += new EventHandler(pipeline_StateChanged); //pipeline.Output.DataReady += new EventHandler(Output_DataReady); //pipeline.InvokeAsync(); //pipeline.Input.Close(); //return; tried these variations that are commented out but none seem to be useful output = pipeline.Invoke(); // Check for errors in the pipeline and throw an exception if necessary if (pipeline.Error != null && pipeline.Error.Count 0) { StringBuilder pipelineError = new StringBuilder(); pipelineError.AppendFormat("Error calling Test() Cmdlet. "); foreach (object item in pipeline.Error.ReadToEnd()) pipelineError.AppendFormat("{0}\n", item.ToString()); throw new Exception(pipelineError.ToString()); } foreach (PSObject psObject in output) { // blah, blah, blah // this is normally where I would read details about a particular PS command // but really pertains to a command once it finishes and has nothing to do with // the verbose messages that I'm after... since this part of the methods pertains // to the after-effects of a command having run, I'm suspecting I need to look to // the asynch invoke method but am not certain or knowing how. } } finally { runspace.Close(); } Thanks!

  • GridViews in ASP.net; C#

    - by user301802
    I am creating gridviews using C# and ASP.net ... I need help in creating 2 gridviews which they have same processID and getting data from different SQL tables in the same database..When I click on the one first row of the first gridview it should give me the list of files with the same processID and its details in the second gridview One process ID has many different xml files stored in it for example processID = 7A413EA4-8ECE-472D-92BE-F58C22E5C567 in the first gridview so all the xml files with the username, date, login date having the same processID in the second table should show up on selecting the row in the first table This is what I have so far done: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="FS_PS2FS._Default" % PS2FS Client                                                                                              " SelectCommand="SELECT [LOG_Id], [LOG_FileName], [LOG_Description], [LOG_Date], [LOG_ProcessId], [LOG_Details], [LOG_UserId] FROM [FS_LOG_PS2FS] ORDER BY [LOG_Date] DESC" </div> <asp:SqlDataSource ID="PS2FS_FS" runat="server" ConnectionString="<%$ ConnectionStrings:FreightsmartWebConnection %>" SelectCommand="SELECT [P2FV_ID], [P2FV_MessageType], [P2FV_MessageText], [P2FV_FileName], [P2FV_ProcessId], [P2FV_CreateDate], [P2FV_CreateUser] FROM [FS_LOG_PS2FS_Validation] ORDER BY [P2FV_CreateDate] DESC"> </asp:SqlDataSource> &nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &nbsp; <asp:GridView ID="LogValidation_GridView" runat="server" AutoGenerateColumns="False" CellPadding="4" DataSourceID="PS2FS_FS" ForeColor="#333333" Height="300px" Width="940px" AllowPaging="True" HorizontalAlign="Center" PageSize="6" OnRowUpdated="LogValidation_GridView_RowUpdated" BorderColor="#999999"> <FooterStyle BackColor="#CCCCCC" Font-Bold="True" ForeColor="Black" CssClass="normal" /> <Columns> <asp:BoundField DataField="P2FV_ProcessId" HeaderText="Process ID" SortExpression="P2FV_ProcessId" Visible="False" /> <asp:BoundField DataField="P2FV_ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="P2FV_ID" /> <asp:BoundField DataField="P2FV_MessageType" HeaderText="Message Type" SortExpression="P2FV_MessageType" /> <asp:BoundField DataField="P2FV_MessageText" HeaderText="Message Text" SortExpression="P2FV_MessageText" /> <asp:BoundField DataField="P2FV_FileName" HeaderText="File Name" SortExpression="P2FV_FileName" /> <asp:BoundField DataField="P2FV_CreateDate" HeaderText="Create Date" SortExpression="P2FV_CreateDate" /> <asp:BoundField DataField="P2FV_CreateUser" HeaderText="Create User" SortExpression="P2FV_CreateUser" /> </Columns> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" BorderStyle="Outset" CssClass="normal" Wrap="True" /> <PagerStyle HorizontalAlign="Center" ForeColor="Black" BackColor="#999999" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> <EditRowStyle BackColor="#999999" /> </asp:GridView> </form>

  • WCF: Configuring Known Types

    - by jerbersoft
    I want to know as to how to configure known types in WCF. For example, I have a Person class and an Employee class. The Employee class is a sublass of the Person class. Both class are marked with a [DataContract] attribute. I dont want to hardcode the known type of a class, like putting a [ServiceKnownType(typeof(Employee))] at the Person class so that WCF will know that Employee is a subclass of Person. Now, I added to the host's App.config the following XML configuration: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.runtime.serialization> <dataContractSerializer> <declaredTypes> <add type="Person, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"> <knownType type="Employee, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral, PublicKeyToken=null" /> </add> </declaredTypes> </dataContractSerializer> </system.runtime.serialization> <system.serviceModel> ....... </system.serviceModel> </configuration> I compiled it, run the host, added a service reference at the client and added some code and run the client. But an error occured: The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://www.herbertsabanal.net:person. The InnerException message was 'Error in line 1 position 247. Element 'http://www.herbertsabanal.net:person' contains data of the 'http://www.herbertsabanal.net/Data:Employee' data contract. The deserializer has no knowledge of any type that maps to this contract. Add the type corresponding to 'Employee' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details. Below are the data contracts: [DataContract(Namespace="http://www.herbertsabanal.net/Data", Name="Person")] class Person { string _name; int _age; [DataMember(Name="Name", Order=0)] public string Name { get { return _name; } set { _name = value; } } [DataMember(Name="Age", Order=1)] public int Age { get { return _age; } set { _age = value; } } } [DataContract(Namespace="http://www.herbertsabanal.net/Data", Name="Employee")] class Employee : Person { string _id; [DataMember] public string ID { get { return _id; } set { _id = value; } } } Btw, I didn't use class libraries (WCF class libraries or non-WCF class libraries) for my service. I just plain coded it in the host project. I guess there must be a problem at the config file (please see config file above). Or I must be missing something. Any help would be pretty much appreciated.

  • Outlook Plug-In for custom CRM

    - by Optimal Solutions
    I would like to write a plug-in that will allow a custom written CRM to read and write to their local Outlook client. I know that this poses a security concern. But, my clients are asking that their CRM "be connected" to Outlook. They would like to be able to do the following: A) When a contact sends them an email (reply or free standing email), they'd like the details of this email to go INTO the CRM. Yep. They would like me to save the body, time and date it was sent, etc. B) They want to be able to send new emails (or replies to existing emails) from within the CRM itself. Basically, "a form that looks like Outlook's send/reply email form". C) Want the ability to search for contacts and the related emails with a search for tags/keywords facility. (i.e. if a product name or code appears in an email then they want the email returned in the search). D) Having performed a search of many contacts, they will want to prepare a mailer and shoot out some sort of email announcement to their qualified leads. This could be 50, 100, or more persons. So its got to be able to allow bulk mailing. E) Given a list of new prospects, that arent currently contacts in the CRM, they will want to do the same and if they get replies from this mailer to the prospects, the will want the replies to be saved in the DB and contacts be inserted into the DB. F) They would like to be able to utilize the calendar and task list facilities of Outlook from the CRM, as well. More or less, they want this pretty basic (as it is today) CRM that I created to integrate with Outlook and have it do so seamlessly as if it was an add-on to the CRM. A plug-in is what I am thinking... But, I dont know where to begin. My environment is Windows XP/Vista and is going to be ASP.NET and I am going to use the VB.NET language to accomplish this. What do I need? Are there resources out there that can describe how to build a plug-in to Outlook as I have been asked to? This is not Exchange, none of the clients use exchange (not so far). They all run Outlook. Mostly 2003. Most clients are XP right now but some are upgrading to Vista. For some reason I cant seem to wrap my head around this. I think the whole security issue is thwarting my ability to see past what is probably a simple thing. The client doesnt want to be prompted by any security messages asking them if they are sure they want to send 382 emails to their contacts. Not once and certainly not 382 times. Where do I begin? I've searched the internet for similar but mainly what I found are already-written products and I've got to write this from scratch.

  • How do I solve an unresolved external when using C++ Builder packages?

    - by David M
    I'm experimenting with reconfiguring my application to make heaving use of packages. Both I and another developer running a similar experiment are running into a bit of trouble when linking using several different packages. We're probably both doing something wrong, but goodness knows what :) The situation is this: The first package, PackageA.bpl, contains C++ class FooA. The class is declared with the PACKAGE directive. The second package, PackageB.bpl, contains a class inheriting from FooA, called FooB. It includes FooB.h, and the package is built using runtime packages, and links to PackageA by adding a reference to PackageA.bpi. When building PackageB, it compiles fine but linking fails with a number of unresolved externals, the first few of which are: [ILINK32 Error] Error: Unresolved external '__tpdsc__ FooA' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external 'FooA::' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external '__fastcall FooA::~FooA()' referenced from blah\FooB.OBJ etc. Running TDump on PackageA.bpl shows: Exports from PackageA.bpl 14 exported name(s), 14 export addresse(s). Ordinal base is 1. Sorted by Name: RVA Ord. Hint Name -------- ---- ---- ---- 00002A0C 8 0000 __tpdsc__ FooA 00002AD8 10 0001 __linkproc__ FooA::Finalize 00002AC8 9 0002 __linkproc__ FooA::Initialize 00002E4C 12 0003 __linkproc__ PackageA::Finalize 00002E3C 11 0004 __linkproc__ PackageA::Initialize 00006510 14 0007 FooA:: 00002860 5 0008 FooA::FooA(FooA&) 000027E4 4 0009 FooA::FooA() 00002770 3 000A __fastcall FooA::~FooA() 000028DC 6 000B __fastcall FooA::Method1() const 000028F4 7 000C __fastcall FooA::Method2() const 00001375 2 000D Finalize 00001368 1 000E Initialize 0000610C 13 000F ___CPPdebugHook So the class definitely seems to be exported and available to link. I can see entries for the specific things ILink32 says it's looking for and not finding. Running TDump on the BPI file shows similar entries. Other info The class does descend from TObject, though originally before refactoring into packages it was a normal C++ class. (More detail below. It seems "safer" using VCL-style classes when trying to solve problems with a very Delphi-ish thing like this anyway. Changing this only changes the order of unresolved externals to first not find Method1 and Method2, then others.) Declaration for FooA: class PACKAGE FooA: public TObject { public: FooA(); virtual __fastcall ~FooA(); FooA(const FooA&); virtual __fastcall long Method1() const; virtual __fastcall long Method2() const; }; and FooB: class FooB: public FooA { public: FooB(); virtual __fastcall ~FooB(); ... other methods... }; All methods definitely are implemented in the .cpp files, so it's not not finding them because they don't exist! The .cpp files also contain #pragma package(smart_init) near the top, under the includes. Questions that might help... Are packages reliable using C++, or are they only useable with Delphi code? Is linking to the first package by adding a reference to its BPI correct - is that how you're supposed to do it? I could use a LIB but it seems to make the second package much larger, and I suspect it's statically linking in the contents of the first. Can we use the PACKAGE directive only on TObject-derived classes? There is no compiler warning using it on standard C++ classes. Is splitting code into packages the best way to achieve the goal of isolating code and communicating through defined layers / interfaces? I've been investigating this path because it seems to be the C++Builder / Delphi Way, and if it worked it looks attractive. But are there better alternatives? I'm very new to using packages and have only known about them through using components before. Any general words of advice would be great! We're using C++Builder 2010. I've fabricated the class and method names in the above code examples, but other than that the details are exactly what we're seeing. Cheers, David

  • Is SQL Server DRI (ON DELETE CASCADE) slow?

    - by Aaronaught
    I've been analyzing a recurring "bug report" (perf issue) in one of our systems related to a particularly slow delete operation. Long story short: It seems that the CASCADE DELETE keys were largely responsible, and I'd like to know (a) if this makes sense, and (b) why it's the case. We have a schema of, let's say, widgets, those being at the root of a large graph of related tables and related-to-related tables and so on. To be perfectly clear, deleting from this table is actively discouraged; it is the "nuclear option" and users are under no illusions to the contrary. Nevertheless, it sometimes just has to be done. The schema looks something like this: Widgets | +--- Anvils (1:1) | | | +--- AnvilTestData (1:N) | +--- WidgetHistory (1:N) | +--- WidgetHistoryDetails (1:N) Nothing too scary, really. A Widget can be different types, an Anvil is a special type, so that relationship is 1:1 (or more accurately 1:0..1). Then there's a large amount of data - perhaps thousands of rows of AnvilTestData per Anvil collected over time, dealing with hardness, corrosion, exact weight, hammer compatibility, usability issues, and impact tests with cartoon heads. Then every Widget has a long, boring history of various types of transactions - production, inventory moves, sales, defect investigations, RMAs, repairs, customer complaints, etc. There might be 10-20k details for a single widget, or none at all, depending on its age. So, unsurprisingly, there's a CASCADE DELETE relationship at every level here. If a Widget needs to be deleted, it means something's gone terribly wrong and we need to erase any records of that widget ever existing, including its history, test data, etc. Again, nuclear option. Relations are all indexed, statistics are up to date. Normal queries are fast. The system tends to hum along pretty smoothly for everything except deletes. Getting to the point here, finally, for various reasons we only allow deleting one widget at a time, so a delete statement would look like this: DELETE FROM Widgets WHERE WidgetID = @WidgetID Pretty simple, innocuous looking delete... that takes over 2 minutes to run, for a widget with no data! After slogging through execution plans I was finally able to pick out the AnvilTestData and WidgetHistoryDetails deletes as the sub-operations with the highest cost. So I experimented with turning off the CASCADE (but keeping the actual FK, just setting it to NO ACTION) and rewriting the script as something very much like the following: DECLARE @AnvilID int SELECT @AnvilID = AnvilID FROM Anvils WHERE WidgetID = @WidgetID DELETE FROM AnvilTestData WHERE AnvilID = @AnvilID DELETE FROM WidgetHistory WHERE HistoryID IN ( SELECT HistoryID FROM WidgetHistory WHERE WidgetID = @WidgetID) DELETE FROM Widgets WHERE WidgetID = @WidgetID Both of these "optimizations" resulted in significant speedups, each one shaving nearly a full minute off the execution time, so that the original 2-minute deletion now takes about 5-10 seconds - at least for new widgets, without much history or test data. Just to be absolutely clear, there is still a CASCADE from WidgetHistory to WidgetHistoryDetails, where the fanout is highest, I only removed the one originating from Widgets. Further "flattening" of the cascade relationships resulted in progressively less dramatic but still noticeable speedups, to the point where deleting a new widget was almost instantaneous once all of the cascade deletes to larger tables were removed and replaced with explicit deletes. I'm using DBCC DROPCLEANBUFFERS and DBCC FREEPROCCACHE before each test. I've disabled all triggers that might be causing further slowdowns (although those would show up in the execution plan anyway). And I'm testing against older widgets, too, and noticing a significant speedup there as well; deletes that used to take 5 minutes now take 20-40 seconds. Now I'm an ardent supporter of the "SELECT ain't broken" philosophy, but there just doesn't seem to be any logical explanation for this behaviour other than crushing, mind-boggling inefficiency of the CASCADE DELETE relationships. So, my questions are: Is this a known issue with DRI in SQL Server? (I couldn't seem to find any references to this sort of thing on Google or here in SO; I suspect the answer is no.) If not, is there another explanation for the behaviour I'm seeing? If it is a known issue, why is it an issue, and are there better workarounds I could be using?

  • Strange intermittent SQL connection error, fixes on reboot, comes back after 3-5 days (ASP.NET)

    - by Ryan
    For some reason every 3-5 days our web app loses the ability to open a connection to the db with the following error, the strange thing is that all we have to do is reboot the container (it is a VPS) and it is restored to normal functionality. Then a few days later or so it happens again. Has anyone ever had such a problem?

  • ASP.NET MVC 2 "value" in IsValid override in DataAnnotation attribute passed is null, when incorrect

    - by goldenelf2
    Hello to all! This is my first question here on stack overflow. i need help on a problem i encountered during an ASP.NET MVC2 project i am currently working on. I should note that I'm relatively new to MVC design, so pls bear my ignorance. Here goes : I have a regular form on which various details about a person are shown. One of them is "Date of Birth". My view is like this <div class="form-items"> <%: Html.Label("DateOfBirth", "Date of Birth:") %> <%: Html.EditorFor(m => m.DateOfBirth) %> <%: Html.ValidationMessageFor(m => m.DateOfBirth) %> </div> I'm using an editor template i found, to show only the date correctly : <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>"%> <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty))%> I used LinqToSql designer to create my model from an sql database. In order to do some validation i made a partial class Person to extend the one created by the designer (under the same namespace) : [MetadataType(typeof(IPerson))] public partial class Person : IPerson { //To create buddy class } public interface IPerson { [Required(ErrorMessage="Please enter a name")] string Name { get; set; } [Required(ErrorMessage="Please enter a surname")] string Surname { get; set; } [Birthday] DateTime? DateOfBirth { get; set; } [Email(ErrorMessage="Please enter a valid email")] string Email { get; set; } } I want to make sure that a correct date is entered. So i created a custom DataAnnotation attribute in order to validate the date : public class BirthdayAttribute : ValidationAttribute { private const string _errorMessage = "Please enter a valid date"; public BirthdayAttribute() : base(_errorMessage) { } public override bool IsValid(object value) { if (value == null) { return true; } DateTime temp; bool result = DateTime.TryParse(value.ToString(), out temp); return result; } } Well, my problem is this. Once i enter an incorrect date in the DateOfBirth field then no custom message is displayed even if use the attribute like [Birthday(ErrorMessage=".....")]. The message displayed is the one returned from the db ie "The value '32/4/1967' is not valid for DateOfBirth.". I tried to enter some break points around the code, and found out that the "value" in attribute is always null when the date is incorrect, but always gets a value if the date is in correct format. The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

If so how? Please help. Sorry if my english is bad not so good in it. Please let know if you need more details. import java.util.Random; public class RadTest extends IntQueue { public static void main(String[] args) { int [] q = new int[10]; Random r = new Random(); int t = 0; int size = 10; while(t != size) { q[t] = (r.nextInt(1000)); t++; } for(int i = 0; i!= size; i++) { System.out.println(q[i]); } System.out.println("Radad: \n"); radixSort(q,size,3); for(int i = 0; i!= size; i++) { System.out.println(q[i]); } } } Hope this is what you were talking about...

  • How do I explain this to potential employers?

    - by ReferencelessBob
    Backstory: TL;DR: I've gained a lot of experience working for 5 years at one startup company, but it eventually failed. The company is gone and the owner MIA. When I left sixth-form college I didn't want to start a degree straight away, so when I met this guy who knew a guy who was setting up a publishing company and needed a 'Techie' I thought why not. It was a very small operation, he sent mailings to schools, waited for orders to start arriving, then ordered a short run of the textbooks to be printed, stuck them in an envelope posted them out. I was initially going to help him set up a computerized system for recording orders and payments, printing labels, really basic stuff and I threw it together in Access in a couple of weeks. He also wanted to start taking orders online, so I set up a website and a paypal business account. While I was doing this, I was also helping to do the day-to-day running of things, taking phone orders, posting products, banking cheques, ordering textbooks, designing mailings, filing end of year accounts, hiring extra staff, putting stamps on envelopes. I learned so much about things I didn't even know I needed to learn about. Things were pretty good, when I started we sold about £10,000 worth of textbooks and by my 4th year there we sold £250,000 worth of text books. Things were looking good, but we had a problem. Our best selling product had peaked and sales started to fall sharply, we introduced add on products through the website to boost sales which helped for a while, but we had simply saturated the market. Our plan was to enter the US with our star product and follow the same, slightly modified, plan as before. We setup a 1-866 number and had the calls forwarded to our UK offices. We contracted a fulfillment company, shipped over a few thousand textbooks, had a mailing printed and mailed, then sat by the phones and waited. Needless to say, it didn't work. We tried a few other things, at home and in the US, but nothing helped. We expanded in the good times, moving into bigger offices, taking on staff to do administrative and dispatch work, but now cashflow was becoming a problem and things got tougher. We did the only thing we could and scaled things right back, the offices went, the admin staff went, I stopped taking a wage and started working from home. Nothing helped. The business was wound up about about 2 years ago. In the end it turned out that the owner had built up considerable debt at the start of business and had not paid them off during good years, which left him in a difficult position when cashflow had started to dry up. I haven't been able to contact the owner since I found out. It took me a while to get back on my feet after that, but I'm now at University and doing a Computer Science degree. How do I show the experience I have without having to get into all the gory details of what happened?

  • How to map an IDictionary<String, CustomCollectionType> in NHibernate

    - by devonlazarus
    Very close to what I'm trying to do but not quite the answer I think I'm looking for: How to map IDictionary<string, Entity> in Fluent NHibernate I'm trying to implement an IDictionary<String, IList<MyEntity>>and map this collection to the database using NHibernate. I do understand that you cannot map collections of collections directly in NHibernate, but I do need the functionality of accessing an ordered list of elements by key. I've implemented IUserCollectionType for my IList<MyEntity> so that I can use IDictionary<String, MyCustomCollectionType> but am struggling with how to get the map to work as I'd like. Details This is the database I'm trying to model: ------------------------ -------------------- | EntityAttributes | | Entities | ------------------------ ------------------ -------------------- | EntityAttributeId PK | | Attributes | | EntityId PK | <- | EntityId FK | ------------------ | DateCreated | | AttributeId FK | -> | AttributeId PK | -------------------- | AttributeValue | | AttributeName | ------------------------ ------------------ Here are my domain classes: public class Entity { public virtual Int32 Id { get; private set; } public virtual DateTime DateCreated { get; private set; } ... } public class EavEntity : Entity { public virtual IDictionary<String, EavEntityAttributeList> Attributes { get; protected set; } ... } public class EavAttribute : Entity { public virtual String Name { get; set; } ... } public class EavEntityAttribute : Entity { public virtual EavEntity EavEntity { get; private set; } public virtual EavAttribute EavAttribute { get; private set; } public virtual Object AttributeValue { get; set; } ... } public class EavEntityAttributeList : List<EavEntityAttribute> { } I've also implemented the NH-specific custom collection classes IUserCollectionType and PersistentList And here is my mapping so far: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" ...> <class xmlns="urn:nhibernate-mapping-2.2" name="EavEntity" table="Entities"> <id name="Id" type="System.Int32"> <column name="EntityId" /> <generator class="identity" /> </id> ... <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <one-to-many class="EavEntityAttributeList" /> </map> </class> </hibernate-mapping> I know the <map> tag is partially correct, but I'm not sure how to get NH to utilize my IUserCollectionType to persist the model to the database. What I'd like to see (and this isn't right, I know) is something like: <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <list> <index column="DisplayOrder"> <one-to-many class="EntityAttributes"> </list> </map> Does anyone have any suggestions on how to properly map that IDictionary<String, EavEntityAttributeList> collection? I am using Fluent NH so I'll take examples using that library, but I'm hand mappings are just as helpful here.

    Please execute the following queries first to set up so that you can help me:- CREATE TABLE IF NOT EXISTS `Tutor_Details` ( `id_tutor` int(10) NOT NULL auto_increment, `firstname` varchar(100) NOT NULL default '', `surname` varchar(155) NOT NULL default '', PRIMARY KEY (`id_tutor`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=41 ; INSERT INTO `Tutor_Details` (`id_tutor`,`firstname`, `surname`) VALUES (1, 'Sandeepan', 'Nath'), (2, 'Bob', 'Cratchit'); CREATE TABLE IF NOT EXISTS `Classes` ( `id_class` int(10) unsigned NOT NULL auto_increment, `id_tutor` int(10) unsigned NOT NULL default '0', `class_name` varchar(255) default NULL, PRIMARY KEY (`id_class`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=229 ; INSERT INTO `Classes` (`id_class`,`class_name`, `id_tutor`) VALUES (1, 'My Class', 1), (2, 'Sandeepan Class', 2); CREATE TABLE IF NOT EXISTS `Tags` ( `id_tag` int(10) unsigned NOT NULL auto_increment, `tag` varchar(255) default NULL, PRIMARY KEY (`id_tag`), UNIQUE KEY `tag` (`tag`), KEY `id_tag` (`id_tag`), KEY `tag_2` (`tag`), KEY `tag_3` (`tag`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=18 ; INSERT INTO `Tags` (`id_tag`, `tag`) VALUES (1, 'Bob'), (6, 'Class'), (2, 'Cratchit'), (4, 'Nath'), (3, 'Sandeepan'), (5, 'My'); CREATE TABLE IF NOT EXISTS `Tutors_Tag_Relations` ( `id_tag` int(10) unsigned NOT NULL default '0', `id_tutor` int(10) default NULL, KEY `Tutors_Tag_Relations` (`id_tag`), KEY `id_tutor` (`id_tutor`), KEY `id_tag` (`id_tag`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; INSERT INTO `Tutors_Tag_Relations` (`id_tag`, `id_tutor`) VALUES (3, 1), (4, 1), (1, 2), (2, 2); CREATE TABLE IF NOT EXISTS `Class_Tag_Relations` ( `id_tag` int(10) unsigned NOT NULL default '0', `id_class` int(10) default NULL, `id_tutor` int(10) NOT NULL, KEY `Class_Tag_Relations` (`id_tag`), KEY `id_class` (`id_class`), KEY `id_tag` (`id_tag`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; INSERT INTO `Class_Tag_Relations` (`id_tag`, `id_class`, `id_tutor`) VALUES (5, 1, 1), (6, 1, 1), (3, 2, 2), (6, 2, 2); In the present system data which I have given , tutor named "Sandeepan Nath" has has created class named "My Class" and tutor named "Bob Cratchit" has created class named "Sandeepan Class". Requirement - To execute a single query with limit on the results to show search results as per AND logic on the search keywords like this:- If "Sandeepan Class" is searched , Tutor Sandeepan Nath's record from Tutor Details table is returned(because "Sandeepan" is the firstname of Sandeepan Nath and Class is present in class name of Sandeepan's class) If "Class" is searched Both the tutors from the Tutor_details table are fetched because Class is present in the name of the class created by both the tutors. Following is what I have so far achieved (PHP Mysql):- <?php $searchTerm1 = "Sandeepan"; $searchTerm2 = "Class"; mysql_select_db("test"); $sql = "SELECT td.* FROM Tutor_Details AS td LEFT JOIN Tutors_Tag_Relations AS ttagrels ON td.id_tutor = ttagrels.id_tutor LEFT JOIN Classes AS wc ON td.id_tutor = wc.id_tutor LEFT JOIN Class_Tag_Relations AS wtagrels ON td.id_tutor = wtagrels.id_tutor LEFT JOIN Tags as t1 on ((t1.id_tag = ttagrels.id_tag) OR (t1.id_tag = wtagrels.id_tag)) LEFT JOIN Tags as t2 on ((t2.id_tag = ttagrels.id_tag) OR (t2.id_tag = wtagrels.id_tag)) where t1.tag LIKE '%".$searchTerm1."%' AND t2.tag LIKE '%".$searchTerm2."%' GROUP BY td.id_tutor LIMIT 10 "; $result = mysql_query($sql); echo $sql; if($result) { while($rec = mysql_fetch_object($result)) $recs[] = $rec; //$rec = mysql_fetch_object($result); echo "<br><br>"; if(is_array($recs)) { foreach($recs as $each) { print_r($each); echo "<br>"; } } } ?> But the results are :- If "Sandeepan Nath" is searched, it does not return any tutor (instead of only Sandeepan's row) If "Sandeepan Class" is searched, it returns Sandeepan's row (instead of Both tutors ) If "Bob Class" is searched, it correctly returns Bob's row If "Bob Cratchit" is searched, it does not return any tutor (instead of only
