Timers: Comparing the Timer Classes in the .NET Framework Class Library

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net
 

Timers often play an important role in both client applications and server-based components (including Windows services). Writing effective timer-driven managed code requires a clear understanding of program flow and the subtleties of the .NET threading model. The .NET Framework Class Library provides three different timer classes: System.Windows.Forms.Timer, System.Timers.Timer, and System.Threading.Timer. Each of these classes has been designed and optimized for use in different situations. This article examines the three timer classes and helps you gain an understanding of how and when each class should be used.

CLR Inside Out: What's New in the .NET Framework 4 Base Class Library

  

Just about everyone who uses Microsoft .NET uses the Base Class Libraries (BCL).When we make the BCL better, almost every managed developer benefits. This column will focus on the new additions to the BCL in .NET 4 beta 1.

Timer usage in a class library

  
Hi all,     I have a class library, inside a class of this library i want to use a timer, such that for every one second a slot should be called. The code for this is as follows: </>public void OnDataReceive() { System.Windows.Forms.Timer t1 = new System.Windows.Forms.Timer(); t1.Enabled = true; t1.Interval = 500; t1.Start(); t1.Tick += new EventHandler(t1_Tick); }   public void t1_Tick(object sender, EventArgs e) { OnReceive(); }   But it is not reaching to this function itself "t1_Tick", Could some one tell me what is wrong in this??? Thanks for any help

Using a GenericHandler as a WebResource inside a Class Library

  

Hi,

I hope this is the right place to ask this question.

I'm trying to make a control class library. I want to have a GenericHandler as a WebResource so I could call it from the web project that will use that control.

I need this handler will get parameters from the query string and return JSON data acourding to what it get in the QS.

I know how to create JS and images WebResources, so I tried the same on a generic handler I added to the class library project but all it does is return the source of the handler file and not the result.

 

Is what I'm trying to do possible? If so, what should I do?

 

Thank :-)


Localization not working in class library (composite control)

  

Hi

I have a class library called WEM.portal which used Resource files to localise text in my composite controls.

I store my resource files (eg MyResourceFile1.resx) in App_GlobalResources folder and then refer to them using

MyLabel1.text = My.Resources.MyResourceFile1.MyResourceKey1

This is all working ok until I create seperate files for each language such as MyResourceFile1.FR-fr.resx.

I have implemented this throughout my other web applications but the Class Library doesnt seem to want to work the same way

When I load the page it correctly showes the resourced keys which I have done through the web application BUT the resource keys in the composite controls does not seem to pick up the culture code.

Am I missing something stupid. Ive tried

  • changing the Build Action on the resource file to Content and Custom tool to GlobalResourceProxyGenerator
  • Creating a resourceManager but to no avail

Class To Contract: Enrich Your XML Serialization With Schema Providers In The .NET Framework

  

The Microsoft .NET Framework 1.x provided minimal options for mapping classes to schemas and serializing objects to XML documents, making this sort of mapping quite a challenge. The .NET Framework 2.0 changes all this with Schema providers and the IXmlSerializable interface.

Zip Your Data: Using the Zip Classes in the J# Class Libraries to Compress Files and Data with C#

  

Zip compression lets you save space and network bandwidth when storing files or sending them over the wire. In addition, you don't lose the directory structure of folders you Zip, which makes it a pretty useful compression scheme. The C# language doesn't have any classes that let you manipulate Zip files, but since .NET-targeted languages can share class implementations, and J# exposes classes in the java.util.zip namespace, you can get to those classes in your C# code. This article explains how to use the Microsoft J# class libraries to create an application in C# that compresses and decompresses Zip files. It also shows other unique parts of the J# runtime you can use from any .NET-compliant language to save some coding.

Debugging Tool: Build a Logging and Event Viewing Library to Help Debug Your .NET Framework-based Ap

  

Building a basic, reusable application framework can make development quicker and easier. This allows you to focus more on the problems at hand and less on the repetitive tasks involved in building any application. In this article, the author presents a framework that provides facilities to access the registry and an extensible framework for logging messages to a console window or the Event Viewer. This reusable framework can be included as a library in your projects, allowing you to display an enhanced, color-coded message log and dynamically change logging levels.

Serial Comm: Use P/Invoke to Develop a .NET Base Class Library for Serial Device Communications

  

Out-of-the-box, the only way of coding RS232 serial communications applications in the .NET environment is to import the outdated and somewhat limited MSComm ActiveX control. This article describes the development of a lean, multithreaded, and modern RS232 base class library in C# managed code. The library uses Platform Invocation Services to interact with the Win32 API directly. Application programmers can use the library from any .NET language through inheritance; the article explores examples written in C# and Visual Basic .NET.

XML in .NET: .NET Framework XML Classes and C# Offer Simple, Scalable Data Manipulation

  

Microsoft .NET introduces a new suite of XML APIs built on industry standards such as DOM, XPath, XSD, and XSLT. The .NET Framework XML classes also include innovations that offer convenience, better performance, and a more familiar programming model, tightly coupled with the new .NET data access APIs-ADO.NET. XmlWriter, XmlReader, and XmlNavigator classes and classes that derive from them, including XMLTextReader and XMLTextWriter, encapsulate a number of functionalities that previously had to be accomplished manually. A discussion of the XMLDOM-Document is also included.

How to get a file path in a class library used by asp.net

  
 Hello,   I have an asp.net application which employs a class project to process xml files. I have an xsd file within the class project. To load the xsd file, I am not sure which path I should use. The following code snippet loads the xsd, and reads the xsd using the StreamReader. I am not sure how to set the value for xsdPath variable.// 2- Read Schema file content StreamReader SR = new StreamReader(xsdPath); // 3- Create a new instance of XmlSchema object XmlSchema Schema = new XmlSchema(); // 4- Set Schema object by calling XmlSchema.Read() method Schema = XmlSchema.Read(SR, new ValidationEventHandler(ReaderSettings_ValidationEventHandler)); Thanks

To get the relative path in the class library

  
Hello, I have to access a relative path of the XSD file to validate a XML file. The XML file and the XSD file are part of the class library. How do I access the relative path in the class library? In case of website, I would use server.mappath(path). Is there anything similar to get the virtual path to the corresponding physical directory on the server in the class library? Thanks

Custom Web Part deployment with class library reference

  
Hi All, We have class library as a project in our solution as well as a web part project. Our web part simply references and executes a service utility class in the class library and outputs it into a label. The deployment is successful but when attempting to add the web part to the page, it comes out with a error page saying "File Not Found" with a correlation ID and date/time reference. Once we take out the code that executes the utility class, it deploys fine and we're able to add it to the page without any issues. It seems evident that any reference to our class library causes this "File Not Found" issue... but we're not sure how to implement this solution. Any ideas? Do we add the class library dll directly into the GAC?  If so, how? Is there another reference we have to implement in the AssemblyInfo.cs?  If so, what does that look like? Any help is appreciated. Thanks, Eric
