Installing Zend Server with WAMP Server

May 13, 2011 Leave a comment

I have tried to install zend server after installing wamp server but zend server wasn’t working properly.The reason was both wamp and zend servers were using the same port 80 you can check it by leftclick on wamp icon->apache->test port 80 it gives message like it is used.So have to do is change zend server port to 81 or if wamp run on port 81 then turn it to 82 or something.

Problem with WAMP Server

May 12, 2011 Leave a comment

I have developed many sites with PHP with WAMP Server.So I thought I had some experience in WAMP.But after installing new WAMP Server I doubt about that.Because it was always offline.WAMP icon shows yellow it means some working but not all.Actually I could use MySQL but not PHP.I tried MySQL by left click Wamp icon->MySQL –>MySQL console it works.I search many blogs and most of says it might be due to Skype or IIS server but I didn’t have installed IIS and I checked by uninstalling Skype,still I got offline color.

Then I tried to stop some other related services in Control Panel\All Control Panel Items\Administrative Tools\Services or you can get that window  by right click MyComputer icon –>manage->Services and Application->Services if you are an administrator of that machine you can start or stop services on that list.But it doesn’t work for me.

I searched it again.Then I found one video with editing some code but it’s boring and so long to edit so I kept that away.after I found a article how to do that simply.just go to WAMP icon & left click->apache->services->test port 80  then I found “your port 80 is actually used by server microsoft-httpapi 2.0” so I found at last it was taken by some other process.So I did change the port no 80 to 81 it works for me.you can edit that one from editing httpd.conf in  WAMP icon & left click->apache->httpd.conf search listen 80 and edit that to 81.

  • no multiple inheritance
  • no pointers(insafe)
  • operator overloading
  • enumerations
  • preprocessor directives
  • CLR-The Common Language Runtime
    • It’s a framework layer the resides above the OS and handles the execution of all .net Applications
    • our .Net Applications

      CLR

      Windows OS

  • MSIL-Microsoft Intermediate Language
    • OS & Hardware independence with cross language relationship
      .Net Code Language Compiler—> MISL
      Code
      Just In Time Compiler(JITler)—> Execution
      native code
  • FCL-The Framework Class Library
    • It contains thousands of classes to provide access to window API and common to common Data Structure,IO,Thread,Streams,Security and network programming
  • CLS-The Common Language Specification
    • It guaranteed to be usable in any other .Net Language
  • CTS-The Common Type System
    • Each .Net compliant language should map its data types to these standard data types
  • GC-Garbage Collection
    • Dynamically allocates memory space

Software Engineering(Short notes-1)

April 25, 2011 Leave a comment
  • Software

Computer Program+Associative documents

  • Attribute of good SW:-
 
    • Maintainability

add component without change

    • Dependability

Safety,Security,reliability

    • Efficiency

minimum # of resources uses

    • Usability

Usable for users

  • Difference between SW n other products

logical rather than physical;
doesn’t ware out ;
difficult to see progress;
developing or engineering not manufacturing

  • Software Engineering
It is a systematic,disciplined,quantifiable approach to development,operation and maintains of SW.
Software Process Set f activities that goal is to develop or evolution of SW.
Basic Steps:-  
Requirement Analysis & Specification Problem definition;
Requirement Analysis
Development Design system & code
Validation & Testing Check whether provide output as customer want
Documentation Manual & associated documents
Maintenance consider how to deal with newly discover problem or new requirement
