Instalarea Java

Posted by admin on July 10, 2011 in Java |

Avem nevoie de trei componente importante pentru a putea programa si executa aplicatii Java. In primul rand Java are nevoie de o masina virtuala JVM instalata pe calculator. Masina virtuala se instaleaza descarcand si instaland pachetul JRE (Java Runtime Environment) de pe siteul http://java.sun.com

Pentru a crea si rula aplicatii Java puteti descarca si instala pachetul JDK (Java Developer Kit).

http://www.oracle.com/technetwork/java/javase/downloads/index.html

JavaTM Platform, Standard Edition Development Kit (JDKTM). The JDK is a development environment for building applications, applets, and components using the Java programming language.

 

The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the JavaTM platform.

Slow Microsoft Office in Windows 7

Posted by admin on March 9, 2011 in IT Suport, Office, Tips & Tricks |

Replacing “normal.dot” to Fix Microsoft Word Problems

Normal.dot Overview: What is Normal.dot?

The Normal.dot is the main default template file in Microsoft Word. Because it contains a lot of customization settings, it is prone to corruption. Ergo, many problems experienced while working in Microsoft Word can be attributed to this file.

The most common fix is to force generate a new, clean version of this troublesome file. This can resolve a lot of problems such as, but not limited to:

  • Word not opening or closing properly
  • Hidden module errors
  • Clearing virus issues
  • Fixing text or formatting problems
  • Seeing the same document every time you open a new Word document

(In Word 2007 and Word 2010 this file is called normal.dotm.)

Solutions:

  • find and delete/rename Normal.dot file
  • restart office or computer
