  • How to give dynamic file name in the appender in log4j.xml

    - by Bittu
    Hi I am using log4j.xml to log the informations. I have used log4j.xml file for creating the log files. I have given the absolute path for each log file in param tag value. eg : appender name="FA" class="org.apache.log4j.DailyRollingFileAppender" param name="DatePattern" value="'_'yyyyMMdd"/ param name="File" value="D:/logFiles/GPreprocessor.log"/ layout class="com.dnb.genericpreprocessor.common.log.AppXMLLayout"/ /appender I do not want to give "GPreprocessor.log" directly.Actually that file name is dynamic based on my project. However the location will always remain same as "D:/logFiles/" . Please help me in this as this is very urgent and important for me.

  • How do I fetch a set of rows from data table

    - by cmrhema
    Hi, I have a dataset that has two datatables. In the first datatable I have EmpNo,EmpName and EmpAddress In the second datatable I have Empno,EmpJoindate, EmpSalary. I want a result where I should show EmpName as the label and his/her details in the gridview I populate a datalist with the first table, and have EmpNo as the datakeys. Then I populate the gridview inside the datatable which has EmpNo,EmpJoinDate and EmpAddress. My code is some what as below Datalist1.DataSource = dt; Datalist1.DataBind(); for (int i = 0; i < Datalist1.Items.Count; i++) { int EmpNo = Convert.ToInt32(Datalist1.DataKeys[i]); GridView gv = (GridView)Datalist1.FindControl("gv"); gv.DataSource = dt2; gv.DataBind(); } Now I have a problem, I have to bind the Details of the corresponding Employee to the gridview. Whereas the above code will display all the details of all employees in the gridview. If we use IEnumerable we give a condition where(a=a.eno=EmpNo), and bind that list to the gridview. How do I do this in datatable. kindly do not give me suggestions of altering the stored procedure which results the values in two tables, because that cannot be altered. I have to find a solution within the existing objects I have. Regards Hema

  • dotNet Templated, Repeating, Databound ServerControl: Modifying underlying ServerControl data per te

    - by Campbeln
    I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... How do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? [edit: Agh... writing the problem out is very cathartic... I'm thinking this is exactly what I will need to do...] Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thinking it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with various <%-tags in place) controls added to the .Controls collection without any other processing?

  • Storing expression references to data base

    - by Marcus
    I have standard arithmetic expressions sotred as strings eg. "WIDTH * 2 + HEIGHT * 2" In this example WIDTH and HEIGHT references other objects in my system and the literals WIDTH and HEIGHT refers to a property (Name) on those objects. The problem I'm having is when the Name property on an expression object changes the expression won't match anymore. One solution I came up with is to instead of storing "WIDTH * 2 + HEIGHT * 2" i store "{ID_OF_WIDTH} * 2 + {ID_OF_HEIGHT} * 2" And let my parser be able to parse this new syntax and implement an interface or such on referenced objects IExpressionReference { string IdentifierName { get; } } Anyone have a better/alternative solution to my problem?

  • C# thread functions not properly sharing a static data member

    - by Umer
    I have a class as following public class ScheduledUpdater { private static Queue<int> PendingIDs = new Queue<int>(); private static bool UpdateThreadRunning = false; private static bool IsGetAndSaveScheduledUpdateRunning = false; private static DataTable ScheduleConfiguration; private static Thread updateRefTableThread; private static Thread threadToGetAndSaveScheduledUpdate; public static void ProcessScheduledUpdates(int ID) { //do some stuff // if ( updateRefTableThread not already running) // execute updateRefTableThread = new Thread(new ThreadStart(UpdateSchedulingRefTableInThrear)); // execute updateRefTableThread.Start(); //do some stuff GetAndSaveScheduledUpdate(ID) } private static void UpdateSchedulingRefTableInThrear() { UpdateSchedulingRefTable(); } public static void UpdateSchedulingRefTable() { // read DB and update ScheduleConfiguration string query = " SELECT ID,TimeToSendEmail FROM TBLa WHERE MODE = 'WebServiceOrder' AND BDELETE = false "; clsCommandBuilder commandBuilder = new clsCommandBuilder(); DataSet ds = commandBuilder.GetDataSet(query); if (ds != null && ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0) { List<string> lstIDs = new List<string>(); for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { lstIDs.Add(ds.Tables[0].Rows[i]["ID"].ToString()); if (LastEmailSend.Contains(ds.Tables[0].Rows[i]["ID"].ToString())) LastEmailSend[ds.Tables[0].Rows[i]["ID"].ToString()] = ds.Tables[0].Rows[i]["TimeToSendEmail"].ToString(); else LastEmailSend.Add(ds.Tables[0].Rows[i]["ID"].ToString(), ds.Tables[0].Rows[i]["TimeToSendEmail"].ToString()); } if (lstIDs.Count > 0) { string Ids = string.Join(",", lstIDs.ToArray()).Trim(','); dhDBNames dbNames = new dhDBNames(); dbNames.Default_DB_Name = dbNames.ControlDB; dhGeneralPurpose dhGeneral = new dhGeneralPurpose(); dhGeneral.StringDH = Ids; DataSet result = commandBuilder.GetDataSet(dbNames, (object)dhGeneral, "xmlGetConfigurations"); if (result != null && result.Tables.Count > 0) { if (ScheduleConfiguration != null) ScheduleConfiguration.Clear(); ScheduleConfiguration = result.Tables[0]; } } } } public static void GetAndSaveScheduledUpdate(int ID) { //use ScheduleConfiguration if (ScheduleConfiguration == null)[1] UpdateSchedulingRefTable(); DataRow[] result = ScheduleConfiguration.Select("ID = "+ID); //then for each result row, i add this to a static Queue PendingIDs } } The function UpdateSchedulingRefTable can be called any time from outside world (for instance if someone updates the schedule configuration manually) ProcessScheduledUpdates is called from a windows service every other minute. Problem: Datatable ScheduleConfiguration is updated in the UpdateSchedulingRefTable (called from outside world - say manually) but when i try to use Datatable ScheduleConfiguration in GetAndSaveScheduledUpdate, i get the older version of values.... What am I missing in this stuff??? About EDIT: I thought the stuff i have not shown is quite obvious and possibly not desired, perhaps my structure is wrong :) and sorry for incorrect code previously, i made a simple function call as a thread initialization... sorry for my code indentation too because i don't know how to format whole block...

  • UICollectionView with one static cell and N dynamic ones from a fetchresultscontroller exception

    - by nflacco
    I'm trying to make a UITableView that shows a blog post and comments for that post. My setup is a tableview in storyboard with two dynamic prototype cells. The first cell is for the post and should never change. The second cell represents the 0 to N comments. My cellForRowAtIndexPath method shows the post cell properly, but fails to get the comment at the given index path (though if I comment out the fetch I get the appropriate number of comment cells with a green background that I set as a visual debug thing). let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment I get the following exception on this line: 2014-08-24 15:06:40.712 MessagePosting[21767:3266409] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x0000000101aa43e5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001037f9967 objc_exception_throw + 45 2 CoreFoundation 0x000000010198f4c3 -[__NSArrayM objectAtIndex:] + 227 3 CoreData 0x00000001016e4792 -[NSFetchedResultsController objectAtIndexPath:] + 162 Section and cell setup: override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete method implementation. // Return the number of rows in the section. switch section { case 0: return 1 default: if let realPost:Post = post { return fetchedResultController.sections[0].numberOfObjects } else { return 0 } } } override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { switch indexPath.section { case 0: let cell = tableView.dequeueReusableCellWithIdentifier(postViewCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = lightGrey if let realPost:Post = self.post { cell.textLabel.text = realPost.text } return cell default: let cell = tableView.dequeueReusableCellWithIdentifier(commentCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = UIColor.greenColor() let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment // <---------------------------- :( cell.textLabel.text = comment.text return cell } } FRC: func controllerDidChangeContent(controller: NSFetchedResultsController!) { tableView.reloadData() } func getFetchedResultController() -> NSFetchedResultsController { fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: nil, cacheName: nil) return fetchedResultController } func taskFetchRequest() -> NSFetchRequest { if let realPost:Post = self.post { let fetchRequest = NSFetchRequest(entityName: "Comment") let sortDescriptor = NSSortDescriptor(key: "date", ascending: false) fetchRequest.predicate = NSPredicate(format: "post = %@", realPost) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } else { return NSFetchRequest(entityName: "") } }

  • Accessing structure through pointers [c]

    - by Blackbinary
    I've got a structure which holds names and ages. I've made a linked-list of these structures, using this as a pointer: aNode *rootA; in my main. Now i send **rootA to a function like so addElement(5,"Drew",**rootA); Because i need to pass rootA by reference so that I can edit it in other functions (in my actual program i have two roots, so return will not work) The problem is, in my program, i can't say access the structure members. *rootA->age = 4; for example doesnt work. Hopefully you guys can help me out. Thanks!

  • Dynamic Data Manipulation using XSLT from XML

    - by Imrul
    I am not working with XSLT not too long. I read that variable of XSLT can't be updated on the fly, so how can i do the following task. I want to sum up Purchase & Sales and put them into a variable, and make some decision according to these values. (For example, if Purchase is greater then sales then do something if not, do something else) <rows> <row> <col attr2="Purchase" >100.00</col> <col attr2="Sales" >100.00</col> </row> <row > <col attr2="Purchase" >19.16</col> <col attr2="Sales" >12.94</col> </row> <row > <col attr2="Purchase" >0.67</col> <col attr2="Sales" >2.74</col> </row> <row > <col attr2="Purchase" >71.95</col> <col attr2="Sales" >61.54</col> </row> <row > <col attr2="Purchase" >3.62</col> <col attr2="Sales" >14.72</col> </row> <row > <col attr2="Purchase">8.80</col> <col attr2="Sales">1.22</col> </row> <row > <col attr2="Purchase" >-4.28</col> <col attr2="Sales" >6.53</col> </row> </rows> if anyone knows, please help me.

  • A very basic auto-expanding list/array

    - by MainMa
    Hi, I have a method which returns an array of fixed type objects (let's say MyObject). The method creates a new empty Stack<MyObject>. Then, it does some work and pushes some number of MyObjects to the end of the Stack. Finally, it returns the Stack.ToArray(). It does not change already added items or their properties, nor remove them. The number of elements to add will cost performance. There is no need to sort/order the elements. Is Stack a best thing to use? Or must I switch to Collection or List to ensure better performance and/or lower memory cost?

  • Binning a numeric variable in R

    - by McPeterson
    I have a vector X that contains positive numbers that I want to bin/discretize. For this vector, I want the numbers [0, 10) to show up just as they exist in the vector, but numbers [10,∞) to be 10+. I'm using: x <- c(0,1,3,4,2,4,2,5,43,432,34,2,34,2,342,3,4,2) binned.x <- as.factor(ifelse(x > 10,"10+",x)) but this feels klugey to me. Does anyone know a better solution or a different approach? mcpeterson

  • send form data as web service in symfony

    - by Lars
    I am making a restrictive portal to a WiFi network using symfony, and I want to send a form as web service to other sites that want to use this portal. How should I solve this? I realize I could go the SOAP/WSDL route, but since symfony is already RESTful, it seems to me I could go the RESTful route with considerably less pain and loss of performance. Right now, I have a working form, but I've only made a casual attempt to bring the form to a remote site by using cURL. The form does not work remotely since the routing is not set up correctly (I think). Can someone help me with this? Thanks.

  • Google Maps Terms of Service - saving some data to a database

    - by R.M.
    I've read the terms of service, and, from what I understand, I'm not allowed to store any information I retrieve from the Google Maps API. Are there any exceptions to this? More to the point, I'm planning on building an application that shows the user several points of interest (like restaurants, libraries etc) at a certain distance around a location he chooses (it can be in one city or more, depending on the distance he chooses). There are two problems: The first problem is that (at least for my country) the geocoder doesn't locate exact addresses, at best it only locates street names (but completely ignores street numbers) in larger cities. It is even worse for smaller rural areas. So the only way to accurately show the places on the map is by storing their coordinates in the database. Another problem seems to be with calculating distances. To show the points located below a certain distance from the user, it would mean I would have to use GDirections to get all distances between the user's location and the other points, to see which ones to show. That would be really slow for the user (since I also have to set a small delay between requests), and it would also send a pretty large amount of requests to google. Would I be allowed to store those distances in a database? The users would not be able to access a list of all the stored information, they would only see the names of the places, and a map with some markers on it. Thank you.

  • Is It Incorrect to Make Domain Objects Aware of The Data Access Layer?

    - by Noah Goodrich
    I am currently working on rewriting an application to use Data Mappers that completely abstract the database from the Domain layer. However, I am now wondering which is the better approach to handling relationships between Domain objects: Call the necessary find() method from the related data mapper directly within the domain object Write the relationship logic into the native data mapper (which is what the examples tend to do in PoEAA) and then call the native data mapper function within the domain object. Either it seems to me that in order to preserve the 'Fat Model, Skinny Controller' mantra, the domain objects have to be aware of the data mappers (whether it be their own or that they have access to the other mappers in the system). Additionally it seems that Option 2 unnecessarily complicates the data access layer as it creates table access logic across multiple data mappers instead of confining it to a single data mapper. So, is it incorrect to make the domain objects aware of the related data mappers and to call data mapper functions directly from the domain objects? Update: These are the only two solutions that I can envision to handle the issue of relations between domain objects. Any example showing a better method would be welcome.
