  • Show loading image when pdf rendering

    - by Pankaj
    I am displaying pdf on my page like this <object data="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>" type="application/pdf" width="960" height="900" style="margin-top: -33px;"> <p> It appears you don't have a PDF plugin for this browser. No biggie... you can <a href="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>">click here to download the PDF file. </a> </p> </object> and Controller function are public FileStreamResult GetPricedMaterialPDF(string projID) { System.IO.Stream fileStream = GeneratePDF(projID); HttpContext.Response.AddHeader("content-disposition", "attachment; filename=form.pdf"); return new FileStreamResult(fileStream, "application/pdf"); } private System.IO.Stream GeneratePDF(string projID) { //create your pdf and put it into the stream... pdf variable below //comes from a class I use to write content to PDF files System.IO.MemoryStream ms = new System.IO.MemoryStream(); Project proj = GetProject(projID); List<File> ff = proj.GetFiles(Project_Thin.Folders.IntegrationFiles, true); string fileName = string.Empty; if (ff != null && ff.Count > 0 && ff.Where(p => p.AccessToUserID == CurrentCustomer.CustomerID).Count() > 0) { ff = ff.Where(p => p.AccessToUserID == CurrentCustomer.CustomerID).ToList(); foreach (var item in ff) { fileName = item.FileName; } byte[] bArr = new byte[] { }; bArr = GetJDLFile(fileName); ms.Write(bArr, 0, bArr.Length); ms.Position = 0; } return ms; } Now my problem is function on controller taking 10 to 20 second to process pdf, data="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>" at that time my page shows blank, which i don't want. i want to show loading image at that time.

  • C++ Unlocking a std::mutex before calling std::unique_lock wait

    - by Sant Kadog
    I have a multithreaded application (using std::thread) with a manager (class Tree) that executes some piece of code on different subtrees (embedded struct SubTree) in parallel. The basic idea is that each instance of SubTree has a deque that store objects. If the deque is empty, the thread waits until a new element is inserted in the deque or the termination criteria is reached. One subtree can generate objects and push them in the deque of another subtree. For convenience, all my std::mutex, std::locks and std::variable_condition are stored in a struct called "locks". The class Tree creates some threads that run the following method (first attempt) : void Tree::launch(SubTree & st, Locks & locks ) { /* some code */ std::lock_guard<std::mutex> deque_lock(locks.deque_mutex_[st.id_]) ; // lock the access to the deque of subtree st if (st.deque_.empty()) // check that the deque is still empty { // some threads are still running, wait for them to terminate std::unique_lock<std::mutex> wait_lock(locks.restart_mutex_[st.id_]) ; locks.restart_condition_[st.id_].wait(wait_lock) ; } /* some code */ } The problem is that "deque_lock" is still locked while the thread is waiting. Hence no object can be added in the deque of the current thread by a concurrent one. So I turned the lock_guard into a unique_lock and managed the lock/unlock manually : void launch(SubTree & st, Locks & locks ) { /* some code */ std::unique_lock<std::mutex> deque_lock(locks.deque_mutex_[st.id_]) ; // lock the access to the deque of subtree st if (st.deque_.empty()) // check that the deque is still empty { deque_lock.unlock() ; // unlock the access to the deque to enable the other threads to add objects // DATA RACE : nothing must happen to the unprotected deque here !!!!!! // some threads are still running, wait for them to terminate std::unique_lock<std::mutex> wait_lock(locks.restart_mutex_[st.id_]) ; locks.restart_condition_[st.id_].wait(wait_lock) ; } /* some code */ } The problem now, is that there is a data race, and I would like to make sure that the "wait" instruction is performed directly after the "deque_lock.unlock()" one. Would anyone know a way to create such a critical instruction sequence with the standard library ? Thanks in advance.

  • How should I model the database for this problem? And which ORM can handle it?

    - by Kristof Claes
    I need to build some sort of a custom CMS for a client of ours. These are some of the functional requirements: Must be able to manage the list of Pages in the site Each Page can contain a number of ColumnGroups A ColumnGroup is nothing more than a list of Columns in a certain ColumnGroupLayout. For example: "one column taking up the entire width of the page", "two columns each taking up half of the width", ... Each Column can contain a number ContentBlocks Examples of a ContentBlock are: TextBlock, NewsBlock, PictureBlock, ... ContentBlocks can be given a certain sorting within a Column A ContentBlock can be put in different Columns so that content can be reused without having to be duplicated. My first quick draft of how this could look like in C# code (we're using ASP.NET 4.0 to develop the CMS) can be found at the bottom of my question. One of the technical requirements is that it must be as easy as possible to add new types of ContentBlocks to the CMS. So I would like model everything as flexible as possible. Unfortunately, I'm already stuck at trying to figure out how the database should look like. One of the problems I'm having has to do with sorting different types of ContentBlocks in a Column. I guess each type of ContentBlock (like TextBlock, NewsBlock, PictureBlock, ...) should have it's own table in the database because each has it's own different fields. A TextBlock might only have a field called Text whereas a NewsBlock might have fields for the Text, the Summary, the PublicationDate, ... Since one Column can have ContentBlocks located in different tables, I guess I'll have to create a many-to-many association for each type of ContentBlock. For example: ColumnTextBlocks, ColumnNewsBlocks and ColumnPictureBlocks. The problem I have with this setup is the sorting of the different ContentBlocks in a column. This could be something like this: TextBlock NewsBlock TextBlock TextBlock PictureBlock Where do I store the sorting number? If I store them in the associaton tables, I'll have to update a lot of tables when changing the sorting order of ContentBlocks in a Column. Is this a good approach to the problem? Basically, my question is: What is the best way to model this keeping in mind that it should be easy to add new types of ContentBlocks? My next question is: What ORM can deal with that kind of modeling? To be honest, we are ORM-virgins at work. I have been reading a bit about Linq-to-SQL and NHibernate, but we have no experience with them. Because of the IList in the Column class (see code below) I think we can rule out Linq-to-SQL, right? Can NHibernate handle the mapping of data from many different tables to one IList? Also keep in mind that this is just a very small portion of the domain. Other parts are Users belonging to a certain UserGroup having certain Permissions on Pages, ColumnGroups, Columns and ContentBlocks. The code (just a quick first draft): public class Page { public int PageID { get; set; } public string Title { get; set; } public string Description { get; set; } public string Keywords { get; set; } public IList<ColumnGroup> ColumnGroups { get; set; } } public class ColumnGroup { public enum ColumnGroupLayout { OneColumn, HalfHalf, NarrowWide, WideNarrow } public int ColumnGroupID { get; set; } public ColumnGroupLayout Layout { get; set; } public IList<Column> Columns { get; set; } } public class Column { public int ColumnID { get; set; } public IList<IContentBlock> ContentBlocks { get; set; } } public interface IContentBlock { string GetSummary(); } public class TextBlock : IContentBlock { public string GetSummary() { return "I am a piece of text."; } } public class NewsBlock : IContentBlock { public string GetSummary() { return "I am a news item."; } }

  • Performance in SQL Mobile with one big column that's not being selected

    - by Anthony Mastrean
    I have a SQL Mobile database with one table. It has several columns with useful, often queried data and one column that stores a relatively large string per record (1000+ characters) that is not queried often. Imagine this fake schema, the "lifeStory" field is the large one. table1 String firstName String lastName String address String lifeStory A representative query would be SELECT firstName, lastName, address FROM table1 WHERE firstName = :p1 Does anyone know of any performance concerns leaving that large, infrequently queried column in this table?

    I want to write a query like this: For a table that has these columns: ColA ColB ColC, ColD select first(ColA, ColB, ColC, ColD) distinct(ColB, ColC) from table order by ColD The query is supposed to order the table by ColD, then group the results by the combination of ColB and ColC (they may have different data types) and returns the first rows (with all the columns of the table) in the groups. How is it possible in MS SQL Server 2005?

I'm barely a newbie on PHP and I'd like not to have to do more than add a tag to the page that needs to do the passing. The data will be anywhere from 5 - 15 characters..only letters and numbers.
