WPF loading animation on a separate UI thread? (C#)

阅读更多关于 WPF loading animation on a separate UI thread? (C#)

Okay, I have a loading animation that runs while a large DataTable is populated to let the user know that the program has not frozen. I have the animation working fine, but it freezes while the DataTable is updatingv as well. Is there some way to have multiple UI threads, so that the animation will continue to run while the DataTable is loading information? EDIT: Current code is below. private void CreateFileTable() { file_data = new DataSet(); data_table = new DataTable(); file_data.Tables.Add(data_table); DataColumn tempCol = new DataColumn("File Name", typeof(string)); data_table.Columns

问题 How do I load the edited .emacs file without restarting Emacs? 回答1: M-x eval-buffer 回答2: I usually use M-x load-file. But be aware that some initialization is only done the first time through. Things like libraries that set their defaults when loaded, but don't get reloaded the second time through. Its always a good idea to start up emacs from scratch as a final check that everything works ok. 回答3: In the *scratch* buffer, type: (load-file user-init-file) Then press C-x C-e to evaluate the

AssemblyResolve event is not firing during compilation of a dynamic assembly for an aspx page

阅读更多关于 AssemblyResolve event is not firing during compilation of a dynamic assembly for an aspx page

问题 This one is really pissing me off. Here goes: My goal is to load assemblies at run-time that contain embedded aspx,ascx etc. What I would also like is to not lock the assembly file on disk so I can update it at run-time without having to restart the application (I know this will leave the previous version(s) loaded). To that end I have written a virtual path provider that does the trick. I have subscribed to the CurrentDomain.AssemblyResolve event so as to redirect the framework to my

difference between dynamic loading and dynamic linking?

阅读更多关于 difference between dynamic loading and dynamic linking?

Routine is not loaded until it is called. All routines are kept on disk in a re-locatable load format. The main program is loaded into memory & is executed. This is called Dynamic Linking. Why this is called Dynamic Linking? Shouldn't it be Dynamic Loading because Routine is not loaded until it is called in dynamic loading where as in dynamic linking, Linking postponed until execution time. Dynamic loading means loading the library (or any other binary for that matter) into the memory during load or run-time. Dynamic loading can be imagined to be similar to plugins , that is an exe can

Java: Which of multiple resources on classpath JVM takes?

阅读更多关于 Java: Which of multiple resources on classpath JVM takes?

If I have multiple files of the same name on classpath (e.g. I have multiple .jar with log4j.properties ), what are the rules JVM follows to chose one? It is specified by the order in which the resources (i.e. usually jar files) are specified using -classpath option. Resources 'earlier' on the classpath take precedence over resources that are specified after them. This can be also set in the manifest file of your application and then you don't need to provide -classpath option. You may want to check these articles on how to work with manifest files. The exhaustive description of "how classes

Aggregate Root references other aggregate roots

阅读更多关于 Aggregate Root references other aggregate roots

I'm currently working a lot with DDD, and I'm facing a problem when loading/operating on aggregate roots from other aggregate roots. For each aggregate root in my model, I also have a repository. The repository is responsible for handling persistence operations for the root. Let's say that I have two aggregate roots, with some members (entities and value objects). AggregateRoot1 and AggregateRoot2. AggregateRoot1 has an entity member which references AggregateRoot2. When I load AggregateRoot1, should I load AggregateRoot2 as well? Should the repository for AggregateRoot2 be responsible for

How do I load css rules dynamically in Webkit (Safari/Chrome)?

阅读更多关于 How do I load css rules dynamically in Webkit (Safari/Chrome)?

问题 I currently have issues in Webkit(Safari and Chrome) were I try to load dynamically (innerHTML) some html into a div, the html contains css rules (...), after the html gets rendered the style definitions are not loaded (so visually I can tell the styles are not there and also if I search with javascript for them no styles are found). I have tried using a jquery plugin tocssRule(), it works but it is just too slow. Is there another way of getting webkit to load the styles dynamically? Thanks.

Show loading progress when making JSF Ajax request

阅读更多关于 Show loading progress when making JSF Ajax request

问题 How can I show some loading message when making request using <f:ajax> ? 回答1: If you're not already using a 3rd party component library which could already have a ready-made component for that, such as PrimeFaces with <p:ajaxStatus>, then you can use the JSF-provided JavaScript jsf.ajax.addOnEvent() function (and eventually also jsf.ajax.addOnError()) to hook a function on ajax events. Here's a basic kickoff example: <script> jsf.ajax.addOnEvent(function(data) { var ajaxstatus = data.status;
