This article describes how a simple Visual C application can create and manage threads. The following list outlines the recommended hardware, software, network infrastructure, and service packs that you need:.
Add a ProgressBar component to the form. And returns output XML like this. Create a model method that takes care of the logic of constructing the XML response to send back. These could be credit cards, websites to scrape, account numbers, etc. In reality, you can send any data you need to work with, and return, then, to the main calling application. The threaded client - A Windows form app The client is visually quite simple. Everything is kicked off by the RunProcess button click event.
We keep track of the start time, and update this when all processes are complete to test how long the process took. We also, at this stage, call an Init method that sets things up for us, assigning some variables and filling the ListView with values. Let's now look at the sequential RunProcess method.
This controls the main body of work for each web request. The number of times to run the process is set by the value of edtTimesToRun. Text which is assigned to the variable RunTimes.
The RunProcess method has a keyword of async - this is important as we are using the await keyword within the RunProcess method. The important part of this code is SendWebRequest - this takes the input, queries the web server, and returns a value that we use to update the UI for the user. SendWebRequest is located in a separate shared.
The shared. This is used to carry data between methods. The SendWebRequest method is again, flagged as async. Add a comment. Active Oldest Votes.

The BackgroundWorker can do the switching for you. Emond Emond You have to select the right way for your application - This article by Jon Skeet is always a bonus to start with. You can call Synchronous methods Asynchronously using any of these styles as per your application design and requirements More difficult situations , such as coordinating the work of multiple threads, or handling threads that block There are a number of ways to expose asynchronous features to client code.
Hope this gives you a head start. Angshuman Agarwal Angshuman Agarwal 4, 6 6 gold badges 35 35 silver badges 85 85 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook.

In simple words, we can say that the three methods we define in our program can be executed by three different threads.
The advantage is that the execution takes place simultaneously. So when multiple threads trying to execute the application code, then the operating system allocates some time period to each thread to execute. Now, in our example, we want to execute the three methods using three different threads let say t1, t2, and t3. The thread t1 is going to execute Method1, thread t2 is going to execute the Method2.
At the same time, the Method3 is going to be executed by thread t3. Let us modify the Program as shown below to execute the methods with different Threads. As you can see in the above code, we have created three different instances of Thread class.
To the constructor of Thread class, we need to pass the method name which needs to be executed by that Thread. Then we call the Start method on the Thread class which will start executing the method.
Here the Main thread is going to create all other Threads. Note: You will not get the output in a sequential manner. Run the application and see the output as shown below. The output may vary in your machine. Here, in this article, I try to explain the concept of Multithreading in C with Examples.
In the next article, I am going to discuss the Constructors of the Thread class. I hope you understood the basics for C Multithreading with Examples and enjoy this article. Your email address will not be published. Skip to content. Previous Lesson Generic Queue in C.
