    Here are some easy ways that can help you fix the caching issue in Windows apps. Caching is a mechanism for improving the performance of any type of service. Technically, caching is the process of storing and accessing data from a cache.

    Does Windows have a file cache?

    By default, Windows logs file data scanned from disks and written to disks. This means that it reads the scan file data from an area of ​​system memory known as the array file cache, and not from our own physical hard drive.

    Recently, a large enterprise and an enterprise application using a front-end GUI whose middle tier includes web services and therefore the database tier experienced application slowdowns, for example when connected to slower network connections. H 256,000 failures. Profiling, although it has been found that most of the data we thought should be re-returned does not always need to be returned, so it was decided to look into using profiling and caching data here to speed up this process.

    While there is a lot of information out there about using caching for large ASP.NET web applications, I haven’t been able to find anything for WinForms applications. While custom searching C# newsgroups, and therefore websites, I began to understand how to implement caching in a .NET application and came across each of our projects accompanying this article. Given that I found this interesting, not to mention that I’m certainly not the only person trying to achieve this, I’ll postl project, code and collected information here for public use. В

    Please note that I’ve only been using the .NET platform and C# since December 2003 (i.e. July 2004) and you can definitely find bugs in the architecture. If so, let me know so I can:< /p >

    The following resources were included (in no particular order, of course) when considering implementing caching:

  • Invalidation of a specific element in the SQL Server ASP.NET Web Application cache.
  • .NET data caching.
  • Caching Architecture Guide for .NET Framework Applications.
  • What are the different types of caching?

    Web caching (browser/proxy/gateway): Browser, proxy and gateway caching work differently, but share the same goal: to moderate all network traffic and latency.Data caching:Application/output caching:Distributed caching:

    The bottom line is that continuing to work on the “Caching Architecture Guide for .NET Framework Applications” is absolutely essential if you want to deepen your understanding and concepts of caching.

    With Code


  • Implement a simple and clean web service to communicate with the Northwind data store through a small DLL to access the data and display the realm Results in DataGrid in WinForm.
  • At the third request for data, a certain time in ticks is determined to retrieve this type of data from the database and a cache is created.
  • Any valid call to query the data will cause it to be fully fetched from the cache. in
  • When the memory cache expires, the data will be retrieved from the database to be updated the next time it is retrieved, and some sort of cache will be created again.
  • When customer table data is considered changed, all caches are notified, expired, restored, and the new record data is displayed in the grid.
  • namespaces

    In order to grant access to the underlying Cache object, we need to say certain namespaces.

  • System.Web – allows us to use the HttpRuntime layer, which finally “provides a set of ASP.NET runtime services for the application” (courtesy of MSDN).


  • System.Web.Caching – You can use the CacheItemRemovedCallback contract, which allows the cache to notify the application aboutb changes.
  • Code

    I’m assuming you already understand the basics of adding a database, creating web services, winforms, etc. So I’ll just follow along and explain the specific caching code. If anyone wants everyone to broach this topic, I’ll share it later.

    In order to use the cache in a WinForms application, we need to instantiate the cache. In ASP.NET applications, we do this for free and simply call:

    Cache.Add(Cache.Add("Key1", "Value 1", null, DateTime.Now.AddSeconds(60),TimeSpan.Zero, CacheItemPriority.High, onRemove)

    caching in windows application

    But in a WinForms application you don’t have a context for this, now we need to create one. To do this, we use each of our HttpRuntime classes in the System.Web namespace. We also need to implement a new FileWatcher object (more on this later).

    What is caching in operating system?

    Caching (pronounced “caching”) is the process of finding the best path to the data in the cache. The memory cache is a temporary storage area. For example, the files that you automatically check when you browse the Internet are stored on your hard drive in a cache subdirectory in your browser directory.

    In our case, we all do this, I would say, the Form_Load event.

    private void Form1_Load(object sender, System.EventArgs e) HttpRuntime httpRT = new HttpRuntime(); FileWatcherClass fd = new FileWatcherClass(@”c:cust_changed.txt”); Fd .OnFileChange += new WindowsApplication1.FileWatcherClass.FileChange(this.FileHasChanged);

    FileWatcher class

    This class is considered a FileWat classcherClass defined in .cs and correctly taken from Microsoft’s “Caching Architecture Guide for .NET Framework Applications”. It takes a parameter associated with the constructor, which is the monitor file. Note that this file must already exist. When the observer detects changes to this document, a delegate is returned, which in our case clears the old memory cache and rebuilds it with the new data.

    Object in cache

    Once the form has undoubtedly loaded, the following blocking code is executed on the “Load” button:

    if(DataCacheGrid != null)    if(!GetCaching())        update the data();different    update the data();dataGrid1.DataSource is a DataCacheGrid; 

    caching in windows application

    We have declared a moving DataCacheGrid element that will be used to hold our data returned by the web service. If this scales to null then we call the refreshdata() method to point directly to the database, which eventually does:
