An IT Solution

Download code example I had searched a lot to make files zip using c#, all the solution provided only support to zip a single file but my requirement is to zip a directory selected by used, I had tried so many utilities but unfortunately all does not works for me. Finally I found a solution which is using Java utility to zip file. This solution is quite easy to implement and debug. To implement this solution you need to add reference of “C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\vjslib.dll” to your application.

Download Code Example I was developing windows application for a well known company of World. This application was in C#.net 2005. As per requirement I have to show user defined message whenever an Exception occurs in the application. The answer is very simply write a simple Try{},Catch{} statement to handle exception. Suppose I have a code of 1000 line unwanted code and error handling creates extra thread while executing the application. I had search on the internet and found a solution to disable the JIT debugger. It works but still it is showing the application information related to functions etc. used in the code. Now, a major issue had risen from client, i.e. he don’t want to show JIT information to user he wants to show his own message whenever any Exception occurs. Offf…. Now that’s the task to which needs to done. I cannot use Try{},Catch{} as this decrease the application performance. Finally I came to the solution. I had wired an event with application to handle applicatio...

When I am working in core asp mail sending is one of the biggest task. For mail sending I have to check for third party on server. I have to according to third party avalibale on different server. But, now say thanks to Microsoft who had made that task easy. Sending a email using ASP.NET 2.0 and C# 2.0 is actually very simple. First, you will need to import the System.Net.Mail namespace. The System.Net.Mail namespace contains the SmtpClient and MailMessage Classes that we need in order to send the email. You have to write this code to your page. public static void Send(string SMTPServerName, string SMTPUserName, string SMTPPassWord, string MailFrom, string MailTo, string CC, string BCC, string Subject, string Body, bool BodyHTML, string Attachment) { MailMessage message = new MailMessage(MailFrom, MailTo, Subject, Body); /******************************************/ //Adding multiple To Addresses foreach (string sTo...

Recommended reading C# optimization tips 1) Return Multiple Resultsets The database code if has request paths that go to the database more than once then, these round-trips decreases the number of requests per second your application can serve. Solution: Return multiple resultsets in a single database request, so that you can cut the total time spent communicating with the database. You'll be making your system more scalable, too, as you'll cut down on the work the database server is doing managing requests. 2) Connection Pooling and Object Pooling Connection pooling is a useful way to reuse connections for multiple requests, rather than paying the overhead of opening and closing a connection for each request. It's done implicitly, but you get one pool per unique connection string. Make sure you call Close or Dispose on a connection as soon as possible. When pooling is enabled, calling Close or Dispose returns the connection to the pool instead of closing the underlying dat...

Recommended read part - 3 14) Avoid Unnecessary Indirection How it affects performance: When you use byRef, you pass pointers instead of the actual object. Many times this makes sense (side-effecting functions, for example), but you don't always need it. Passing pointers results in more indirection, which is slower than accessing a value that is on the stack. Solution: When you don't need to go through the heap, it is best to avoid it there by avoiding indirection. 15) Use "ArrayLists" in place of arrays How it improves performance An ArrayList as everything that is good about an array PLUS automatic sizing, Add, Insert, Remove, Sort, Binary Search. All these great helper methods are added when implementing the IList interface. Tradeoffs: The downside of an ArrayList is the need to cast objects upon retrieval. 16) Always check Page.IsValid when using Validator Controls Always make sure you check Page.IsValid before processing your forms when using Validator Controls. ...

All the activities you do to the string are stored in the memory as separate references and it must be avoided as much as possible. i.e. When a string is modified, the run time will create a new string and return it, leaving the original to be garbage collected. Most of the time this is a fast and simple way to do it, but when a string is being modified repeatedly it begins to be a burden on performance: all of those allocations eventually get expensive. Solution: Use String Builder when ever string concatenation is needed so that it only stores the value in the original string and no additional reference is created. 7) Avoid throwing exceptions How it affects performance: Exceptions are probably one of the heaviest resource hogs and causes of slowdowns you will ever see in web applications, as well as windows ...

Recommended Read Part - 1 3) Disable View State of a Page if possible View state is a fancy name for ASP.NET storing some state data in a hidden input field inside the generated page. When the page is posted back to the server, the server can parse, validate, and apply this view state data back to the page's tree of controls. View state is a very powerful capability since it allows state to be persisted with the client and it requires no cookies or server memory to save this state. Many ASP.NET server controls use view state to persist settings made during interactions with elements on the page, for example, saving the current page that is being displayed when paging through data. How it affects performance: There are a number of drawbacks to the use of view state, however. It increases the total payload of the page both when served and when requested. There is also an additional overhead incurred when serializing or deserializing view state data that is posted back to the server. ...

Performance tuning can be tricky. It's especially tough in Internet-related projects with lots of components running around, like HTML client, HTTP network, Web server, middle-tier components, database components, resourcemanagement components, TCP/IP networks, and database servers. Performance tuning depends on a lot of parameters and sometimes, by changing a single parameter, performance can increase drastically. Introduction This document lists out some tips for optimizing ASP.Net Web applications and many traps and pitfalls are discussed as follows : Tips For Web Application 1) Turn off Tracing unless until required Tracing is one of the wonderful features which enable us to track the application's trace and the sequences. However, again it is useful only for developers and you can set this to "false" unless you require to monitor the trace logging. How it affects performance: Enabling tracing adds performance overhead and might expose private information, so it s...
