  • create jrml file at run time and modify at run time

    - by Srinivas
    Hi I have a requirement to develop custom reports where we already have some reoprts developed using JasperReports using iReport tool. Now the requirement is to modify those reports design at run time. I should use those existing jrxml files and save as to new report then change the design at run time. Also I should see those newly created reports whenever I want. I have gone through the Jasper API and Dynamic Reports where we can create the reports dynamically at run time but we can't save the design (like JRXML). I am looking for any other JRXML design API to create and modify and save the Jasper Reports at run time. I appreciate if any one can help me. Thanks in Advance Srinivas

    - by Eatdoku
    Hi, I am looking for a solution for user use the browser's back button to navigate to previous page once logged out. I have a web application build in asp.net and using a custom membership provider for authentication and authorization. Everything works fine except when the user click on the logout link to log out of the application and being redirect to a default cover page, if the use click on the BACK BUTTON on their browser, it will actually go back to where they were before and the data will still show up. Of course they can't do anything on that page, click on anything link they will be redirect to a login page again. But having those information display is making a lot users confused. i am just wondering if there is any way i can either clear the browser's history so use can't go BACK, or when they click on the back button and have them redirect to the login page. thanks

  • Making only the outer vector in vector<vector<int>> fixed

    - by Dennis Ritchie
    I want to create a vector<vector<int>> where the outer vector is fixed (always containing the same vectors), but the inner vectors can be changed. For example: int n = 2; //decided at runtime assert(n>0); vector<vector<int>> outer(n); //outer vector contains n empty vectors outer.push_back(vector<int>()); //modifying outer vector - this should be error auto outer_it = outer.begin(); (*outer_it).push_back(3); //modifying inner vector. should work (which it does). I tried doing simply const vector<vector<int>>, but that makes even the inner vectors const. Is my only option to create my own custom FixedVectors class, or are there better ways out there to do this?

  • Is NetNamedPipeBinding binding guaranteed to work only on the same machine?

    - by Asaf R
    Hi, I've created a Windows Service that uses WCF for communications to it. The service should be used be called only from the same machine. If I can guarantee that there's no way to communicate with it from another machine, I can consider it secured. Since I'm using communications on a single machine, I opted to used NetNamedPipeBinding. This bindings documentation says it's Optimized for on-machine communications, but does not give any guarantees. My questions is, does NetNamedPipeBinding provide on-machine-only guarantees? If not what binding does, or how would you go implementing a custom bindings that does provide such guarantees? Thanks, Asaf

  • What exactly are tuples in Python?

    - by Sergio Tapia
    I'm following a couple of Pythone exercises and I'm stumped at this one. # C. sort_last # Given a list of non-empty tuples, return a list sorted in increasing # order by the last element in each tuple. # e.g. [(1, 7), (1, 3), (3, 4, 5), (2, 2)] yields # [(2, 2), (1, 3), (3, 4, 5), (1, 7)] # Hint: use a custom key= function to extract the last element form each tuple. def sort_last(tuples): # +++your code here+++ return What is a Tuple? Do they mean a List of Lists?

  • [LINQ]InsertOnSubmit NullReferenceException

    - by Kurresmack
    Hello, I have a rather annoying issue with LinqToSql. I have created a class that is derived from the class in the DataContext. The problem is that as soon as I use "InsertOnSubmit(this);" on this derived class I get a NullReferenceException. I've seen some people with the same issue. However they've used a custom constructor and solved the issue by calling ": this()" like this thread http://social.msdn.microsoft.com/Forums/en-US/linqprojectgeneral/thread/0cf1fccb-6398-4f16-920b-adef9dc4ac9f The difference is that I use a default constructor which causes the base constructor to be called so there should not be any problem! Could someone please help me with this, starts to get annoying! Thanks :)

  • Eclipse standard warning/error overlay icons

    - by pulzar
    I'm writing an Eclipse plug-in... In my custom label decorator, I want to overlay a warning icon, and I'd like to use the standard one used by eclipse (the little yellow triangle). How can I get an image descriptor of this icon? I tried using workbench.getSharedImages().getImageDescriptor(ISharedImages .IMG_DEC_FIELD_WARNING), since that ID seems to match what I'm looking for, but the shared images collection doesn't actually have that image in it (so I just get a null returned). Is there some other shared image collection that I should be looking at?

  • Ajax and Brower Navigation for Back/Forward

    - by David Rodecker
    I am using a ASP.net form with custom onclick mouse events to modify data values. Upon clicking and updating the values, one div section of the form performs a postback. onclick="__doPostBack('ctl01$phCon1$gridReports','sel1')" This is working well, however when the browser BACK option is selected, the browser opens goes through the history of the DIV ajax/onclick actions prior to going back to the prior URL. I suspect that this may be due to the doPostBack being treated as a browsing operation. Is there a means to perform the necessary ASP.net code events to make the page work, but not have the action stored in the browser history?

  • ASP.NET MVC: How to serve content while returning status code 404?

    - by Marek
    I would like to serve a user friendly "not found" page in my ASP.NET MVC application while providing a 404 status code. (based on this answer) I already have the mechanism how to catch an invalid route and the custom 404 page is served by my ErrorController/Handle404 action. My current implementation of Handle404: public ActionResult Handle404() { Response.StatusCode = 404; return View("NotFound"); } Currently, IIS serves the page as 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. (the standard IIS page, not my user friendly content) How can I include the 404 status code in the result served by the Handle404 action while still serving the content?

  • Using WFC authentication service for web application

    - by user200295
    I am using a WFC authentication service I set up with a web application. I have successfully set up and tested the AuthenticationService and RolesService. The web application can successfully call methods like ValidateUser and GetRolesForCurrentUser through the WFC services. I want to integrate the WFC authentication service with my web.config and site.map. Do I need to write a custom provider, or is there some way I can modify the web.config of the web application to use the WFC authentication service as its membership provider? This way I can set what roles have access to what directories based off the WFC authentication service.

  • First Tap on customcell of uitableview should expand it and second should contract it.

    - by neha
    Hi all, In my application I have this requirement that first tap on custom cell of uitableview with a label in it should expand it and second should contract it. I'm able to expand and contract cell and expand label inside cell, but not able to contract the label on second tap. I'm using this function - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; if( selected == YES ) { [self expandRow]; } else { [self contractRow]; } height = [lblFeed frame].size.height + 75; } expandRow expands the label and contractRow contracts it. I'm perplexed as for how many rows this function gets called. It doesn't get called only for the cell tapped, it gets called more number of times for single tap on single cell may be for other cells but I'm not getting which rows. This' really urgent. Can anybody please help?

  • Container Options in AWS Elastic Beanstalk

    - by Sangram Anand
    We have deployed a java webapplication in Elastic Beanstalk with the minimum instance count 1 and max instance count 2 for Autoscaling. The custom AMI we are using is c1.medium with Sun JDK 6. The environment status changed to yellow and then red. After checking into the log file from the snapshot logs we found a exception - Caused by: java.lang.OutOfMemoryError: Java heap space. Assuming this could be one of the possible reason for the Environment failure. The settings that we have configured in the Environment Container option are Initial JVM Heap Size (MB) - 256M Maximum JVM Heap Size (MB) - 512m The maximum heap size the java virtual machine will ever consume, specified on the JVM launch command line using -Xmx. Maximum JVM Permanent Generation Size (MB) - 512m Should i increase the Heap size from 512m to more or is it fine.

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible

  • SPGridView current item in Sharepoint

    - by pistacchio
    Hi, I'm making a custom webpart. I takes some items from a list and display them with a SPGridView. I bound the fields like this: // Grab data from a SP List into dvwTickets SPGridView grdMyTickets = new SPGridView(); grdMyTickets.DataSource = dvwTickets; [..] BoundField colTicketTypology = new BoundField(); colTicketTypology.DataField = "ID"; colTicketTypology.HeaderText = ticketList.Fields.GetFieldByInternalName("ID").Title; grdMyTickets.Columns.Add(colTicketTypology); [..] This works. Now, what a grid does behind the scene when binding data to it is cycling through the binded data. How can I access the "Current Item" to make operations on each item while binding? Thanks

  • Dynamically populate an InfoPath DropownList with managed code

    - by Jared
    I have an InfoPath form with custom C# code, and a Sharepoint list. I have a dropdownlist in the InfoPath form that I want to populate with a certain field from the Sharepoint list (I want the InfoPath dropdownlist to contain this field's value from every item in the Sharepoint list. I can successfully get the list of values I need from Sharepoint in my managed code, but I do not see how I can get these values into the dropdownlist (either bind to the list, or add each item in the list one by one). I thought I could modify the XML of the dropdownlist to insert my items, but the XML only contains the first item in the dropdownlist: <my:RelatedRiskID xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2009-07-20T18:12:59">Option 1</my:RelatedRiskID> I feel like this should be possible, but I can't find any resources on how to do it. Thanks in advance for the help. Jared

  • How t have the RDLC pie chart show ranges instead of individual values

    - by Emad
    I have some data coming from a custom dataset that look like the following example Person Age P1 20 P2 21 P3 30 P4 31 P5 40 And I want to develop a pie showing the age distribution against the age. The point is that I want this Age to be shown in ranges. (20-29, 30-39, etc for example So we have: Slice with total number =2 (P1 + P2) as age is 20-29 (one at 20 and another at 21) Slice with total number =3 (P3 + P4) as age is 30-39 (one at 30 and another at 31) Slice with total number =1 (P5) as age is 40 (one at 40). How can i customize the pie chart to aggregate values by ranges that I can define?

  • Weird behaviour of the app.config deployment after updating it.

    - by Dabblernl
    I moved some hardcoded settings to a custom Section (so I did not use the <appSetting tag) in the app.config of my ClickOnce application. When updating, the clients got an error stating that the server gave a 404 not found error for the file "myapp.exe.config.deploy". Browsing on the server I did find the changed app.config there, only it was named app.config.deploy. Thinking to be smart I renamed the app.config to myapp.exe.config on the development machine and published again. That did not work... However after naming the file back to app.config and publishing the error went away and the clients used the setting happily! Please explain what went wrong?

  • migrating webclient to WCF; WCF client serializes parametername of method

    - by Wouter
    I'm struggling with migrating from webservice/webclient architecture to WCF architecture. The object are very complex, with lots of nested xsd's and different namespaces. Proxy classes are generated by adding a Web Reference to an original wsdl with 30+ webmethods and using xsd.exe for generating the missing SOAPFault objects. My pilot WCF Service consists of only 1 webmethod which matches the exact syntax of one of the original methods: 1 object as parameter, returning 1 other object as result value. I greated a WCF Interface using those proxy classes, using attributes: XMLSerializerFormat and ServiceContract on the interface, OperationContract on one method from original wsdl specifying Action, ReplyAction, all with the proper namespaces. I create incoming client messages using SoapUI; I generated a project from the original WSDL files (causing the SoapUI project to have 30+ methods) and created one new Request at the one implemented WebMethod, changed the url to my wcf webservice and send the message. Because of the specified (Reply-)Action in the OperationContractAttribute, the message is actually received and properly deserialized into an object. To get this far (40 hours of googling), a lot of frustration led me to using a custom endpoint in which the WCF 'wrapped tags' are removed, the namespaces for nested types are corrected, and the generated wsdl get's flattened (for better compatibility with other tools then MS VisualStudio). Interface code is this: [XmlSerializerFormat(Use = OperationFormatUse.Literal, Style = OperationFormatStyle.Document, SupportFaults = true)] [ServiceContract(Namespace = Constants.NamespaceStufZKN)] public interface IOntvangAsynchroon { [OperationContract(Action = Constants.NamespaceStufZKN + "/zakLk01", ReplyAction = Constants.NamespaceStufZKN + "/zakLk01", Name = "zakLk01")] [FaultContract(typeof(Fo03Bericht), Namespace = Constants.NamespaceStuf)] Bv03Bericht zakLk01([XmlElement("zakLk01", Namespace = Constants.NamespaceStufZKN)] ZAKLk01 zakLk011); When I use a Webclient in code to send a message, everything works. My problem is, when I use a WCF client. I use ChannelFactory< IOntvangAsynchroon to send a message. But the generated xml looks different: it includes the parametername of the method! It took me a lot of time to figure this one out, but here's what happens: Correct xml (stripped soap envelope): <soap:Body> <zakLk01 xmlns="http://www.egem.nl/StUF/sector/zkn/0310"> <stuurgegevens> <berichtcode xmlns="http://www.egem.nl/StUF/StUF0301">Bv01</berichtcode> <zender xmlns="http://www.egem.nl/StUF/StUF0301"> <applicatie>ONBEKEND</applicatie> </zender> </stuurgegevens> <parameters> </parameters> </zakLk01> </soap:Body> Bad xml: <soap:Body> <zakLk01 xmlns="http://www.egem.nl/StUF/sector/zkn/0310"> <zakLk011> <stuurgegevens> <berichtcode xmlns="http://www.egem.nl/StUF/StUF0301">Bv01</berichtcode> <zender xmlns="http://www.egem.nl/StUF/StUF0301"> <applicatie>ONBEKEND</applicatie> </zender> </stuurgegevens> <parameters> </parameters> </zakLk011> </zakLk01> </soap:Body> Notice the 'zakLk011' element? It is the name of the parameter of the method in my interface! So NOW it is zakLk011, but it when my parameter name was 'zakLk01', the xml seemed to contain some magical duplicate of the tag above, but without namespace. Of course, you can imagine me going crazy over what was happening before finding out it was the parametername! I know have actually created a WCF Service, at which I cannot send messages using a WCF Client anymore. For clarity: The method does get invoked using the WCF Client on my webservice, but the parameter object is empty. Because I'm using a custom endpoint to log the incoming xml, I can see the message is received fine, but just with the wrong syntax! WCF client code: ZAKLk01 stufbericht = MessageFactory.CreateZAKLk01(); ChannelFactory<IOntvangAsynchroon> factory = new ChannelFactory<IOntvangAsynchroon>(new BasicHttpBinding(), new EndpointAddress("http://localhost:8193/Roxit/Link/zkn0310")); factory.Endpoint.Behaviors.Add(new LinkEndpointBehavior()); IOntvangAsynchroon client = factory.CreateChannel(); client.zakLk01(stufbericht); I am not using a generated client, i just reference the webservice like i am lot's of times. Can anyone please help me? I can't google anything on this...

  • CSS inheritance: applying selector for itself and every descendant

    - by Cawas
    Get a custom user CSS and type this .answered-accepted { color: white !important; background: #090 !important; } Now go to answers.unity3d and look for an accepted answer. The design looks bad, because the <strong> in there overrides the customization. The fix I've found is this: .answered-accepted, .answered-accepted * { color: white !important; background: #090 !important; } Now it looks fine on the website, but the code looks ugly!! How can I do this without repeating the class name?

  • C# .Net file in use issue

    - by Dan
    I'm having an issue opening files that have recently been closed by the .Net framework. Basically, what happens is the following: -Read in an XML file using DataSet.ReadXml() -Make some changes to the data -Write out the XML file using DataSet.WriteXml() -Copy the XML file to a new location using File.Copy -FTP the file using a custom control This sequence can intermittently fail either after the WriteXML or the File.Copy with a file in use exception. I'm guessing it could be the Windows write cache not flushing right away. Can anyone confirm that this could be causing my issue? Any solutions to suggest? Thanks, Dan

  • jQuery counter to count up to a target number

    - by Matt Huggins
    I'm trying to find out if anyone knows about an already existing jQuery plugin that will count up to a target number at a specified speed. For example, take a look at Google's number of MB of free storage on the Gmail homepage, under the heading that reads "Lots of space". It has a starting number in a <span> tag, and slowly counts upward every second. I'm looking for something similar, but I'd like to be able to specify: The start number The end number The amount of time it should take to get from start to end. A custom callback function that can execute when a counter is finished.

  • 3rd party data - Store in Data Warehouse or Primary database?

    - by brydgesk
    This is mostly a data warehouse philosophy question. My project involves an Oracle forms application, and a Teradata Data Warehouse for reporting and ad-hoc purposes. In addition to the primary data created by the users of our application, we also require data from various other sources. Currently, this 3rd party data comes via FTPd flat files directly to our Data Warehouse. To access the data, our users must use a series of custom BusinessObjects reports. My question is, would it make more sense for this data to be sent to our source Oracle system instead? Is it ever appropriate for a Data Warehouse to be the point of origin for users to access raw data? In short, is it more important that the operational database contain only the data created by your project, or that the data warehouse remain dedicated solely to reporting and analysis?
