How to Wait for the Completion of the BookmarkCallback method?

Posted By:      Posted Date: September 08, 2010    Points: 0   Category :Windows Application
Hi I have a custom activity, which create a bookmark. In the callback method, I am setting some data to the object, which I need back to host application. It is just like protected override void Execute(NativeActivityContext context) { context.CreateBookmark(EventName, new BookmarkCallback(this.HandleEvent));} private void HandleEvent(NativeActivityContext context, Bookmark bookmark, object obj) { if (obj != null) { Dictionary<string, object> dat = obj as Dictionary<string, object>; dat.Add("NewValue", "value1"); } } From the host, I am resuming the bookmark as workflowApp.ResumeBookmark("Next", data); if (data.ContainsKey("NewValue")) { newValue = data["NewValue"].ToString(); } ResumeBookmark will execute only when the WorkflowApplication goes Idle; so I am not getting the value back just after the ResumeBookmark. How can I wait for the Completion of the ResumeBookmark? I tried with the BeginResumeBookmark() & EndResumeBookmark() methods too. EndResumeBookmark() doesn't mean that the callback method execution is completed. Either, I need to make the WorkflowApplication to go Idle state or I need to wait for the completion of the ResumeBookmark(Callback method completion). Note:  We are using the UI thread for executing the workflow          &n

Windows 2000: Asynchronous Method Calls Eliminate the Wait for COM Clients and Servers


Windows 2000 is the first version of COM to support asynchronous method calls, which permit clients to make nonblocking calls to COM objects and objects to process incoming calls without blocking the calling threads. COM clients benefit from asynchronous method calls because they can continue working while waiting for outbound calls to return. Objects benefit because they can queue incoming calls and service them from a thread pool. Our SieveClient and SieveServer sample apps demonstrate how to create and use asynchronous clients and servers in COM-based distributed applications.

SSIS Script Task wait for remote process completion - WMI & C#

Hi All: I have a C# script task that uses WMI to create a process on a remote machine. What is the best way for me to make the script task wait until the remote process has completed before moving to the next task in SSIS? TIA!

Thinking about new C# method prototypes: object as dictionary

I recently had to write a small Flickr API. I know many .Net API for Flickr already exist but I needed one for a Silverlight application. Whatever, it's only about building some querystrings so I did it by myself. It's been an opportunity to think again about a classical question: how to pass parameters to a method ?

Imagine you have a generic method to call some Flickr functions.

Sys.Net.WebServiceFailedException: The server method '' failed with the following error:



Let's say we have 2 time consuming functions, aaa and aaa1 inside a aspx page.

        public static string aaa(int i)

            return i.ToString();

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

.NET Delegates: Making Asynchronous Method Calls in the .NET Environment


One of the many great features of the .NET Framework is that it has asynchronous infrastructure built in. In .NET you can call any method asynchronously by defining a delegate for the method and calling the delegate's asynchronous methods. This is beneficial to your application because when a synchronous call is made, the calling thread is blocked until the method completes whereas an asynchronous call is made on a different thread, and this allows the original thread to continue its work while the asynchronous call is in progress.This article explains delegates in .NET and how to use them to perform asynchronous calls, eliminating age-old threading problems.

Windows Sockets 2.0: Write Scalable Winsock Apps Using Completion Ports


Writing a network-aware application isn't difficult, but writing one that is scalable can be challenging. Overlapped I/O using completion ports provides true scalability on Windows NT and Windows 2000. Completion ports and Windows Sockets 2.0 can be used to design applications that will scale to thousands of connections. The article begins with a discussion of the implementation of a scalable server, discusses handling low-resource, high-demand conditions, and addresses the most common problems with scalability.
