C++ dynamic memory allocation with arrays in a structure

阅读更多关于 C++ dynamic memory allocation with arrays in a structure

问题 There have been similar questions to this but they are all in C, rather than C++, so I have asked a new question. I have been following a C++ tutorial and after completing the dynamic memory, pointers and structure sections I tried to put them together in an example program. Essentially, I am trying to have a dynamically allocated array of a structure (the program inputs "produce" :P and displays the result). The compiler errors: 'base operand of '->' has non-pointer type 'produce' for the

PHP script that reports progress to Client

阅读更多关于 PHP script that reports progress to Client

问题 I'm writing a PHP script that does a lot of repetitive work, and when the client executes it, I'd like it to send back HTML in some way, dynamically, as it completes tasks. (without AJAX?) How can this be done? 回答1: You can flush the output buffer, using flush(); So something like: taskOne(); echo 'Task one finished'; flush(); ... Hope this helps. 回答2: Maybe you can use refresh-meta tag, or HTTP header, like this: header("Refresh: 3; URL=http://www.some.org/some.html"); The browser will then

问题 EDIT With one of the below answers, I was able to correct this issue for the rendering within a table. I'm still seeing this issue within my ListViews. I've tried this CSS for the ListView, but it has not corrected the issue. /* FIX FOR CALENDAR IN TABLE */ .DateTime_Edit { white-space: nowrap; } .DateTime_Edit table { border: solid 0 #FFFFFF; width: 0; height: 0; padding: 0; margin: 0; } .DateTime_Edit table tr td { border: solid 0 #FFFFFF; padding: 0; margin: 0; } /* LISTVIEW, NOT WORKING *

问题 This is similar to Odd Exception in MVC 3 Project. We have an ASP.NET 4.0 application running in full trust. We need to have the following line in our web.config, otherwise one of the libraries we are using does not function. (As it explicitly uses the now obsolete CAS model from previous versions of .NET). <trust legacyCasModel="true" /> Given this setting, we are unable to use the dynamic keyword or certain features of ASP.NET MVC which rely on it. As an example, the following code causes

ASP.Net Dynamic Data or MVC2?

阅读更多关于 ASP.Net Dynamic Data or MVC2?

问题 I've been working with web-forms and I want to switch to the MVC pattern based on some facts and other goodies that I see in it. I was going good with MVC review when I came across the latest Dynamic Data (which in past was called Dynamic Data Templates). Correct me if I'm wrong but I believe in backend both MVC2 & DD use the MVC pattern but then DD supports server-side controls and has a lot of automation using its latest scaffolding technique. We can make a running website with-in a few

Dynamic Allocation of Constant memory in CUDA

阅读更多关于 Dynamic Allocation of Constant memory in CUDA

问题 I'm trying to take advantage of the constant memory, but I'm having a hard time figuring out how to nest arrays. What I have is an array of data that has counts for internal data but those are different for each entry. So based around the following simplified code I have two problems. First I don't know how to allocate the data pointed to by the members of my data structure. Second, since I can't use cudaGetSymbolAddress for constant memory I'm not sure if I can just pass the global pointer

阅读更多关于 Define Scaffolding. (with respect to Dynamic Data and ASP.NET MVC)

问题 There is a lot of information about how to implement and customize scaffolding with Dynamic Data and ASP.NET MVC. What exactly is the definition of scaffolding when used in this context? 回答1: It means that the Dynamic Data framework will auto-generate a set of routes based on the table names in a data model (e.g. a Linq to SQL data context), and a predefined set of operations (essentially CRUD). When you e.g. visit http://example.com/Products/Details.aspx , where "Products" is the name of a
