After installing nomachine, if you get an error connecting whereby nomachine errors out after  "Negotiating link parameters"
 

When installing nomachine on redhat 5.3 64-bit be sure to:

  1. Make sure you have installed the 64-bit packages as the 32-bit ones will not work.
  2. add the hostname to /etc/hosts
  3. Check "Disable encryption of all traffic" (in configuration / advanced tab)
On Centos 32-bit:
  1. add the hostname to /etc/hosts
  2. make sure the host IP is not specified as 127.0.0.1 line
  3. Uncheck "Disable encryption of all traffic" (in configuration / advanced tab)

  • Support for Subversion.
  • Access to commonly used source control operations via contextual menu [screenshot]
  • Dynamic icon badging for files under version control. Shows the status of your files visually. [ screenshot ]

TIP
The Recital Oracle Gateway requires the Oracle libclntsh.so shared library.  If this file is unknown to ld.so.conf, add it using the ldconfig command.

The Recital Universal ODBC Driver is a 32 bit implementation, so is not listed in the 64 bit ODBC Data Source Administrator, which is the default administrator accessed from Control Panel | Administration Tools.

So, to create and configure Recital ODBC datasources, you need to use the Window 32 bit ODBC Data Source Administrator or Recital's own  Recital Universal ODBC Manager (32-bit).

The Window 32 bit ODBC Data Source Administrator is %windir%\SysWOW64\odbcad32.exe.
The Recital Universal ODBC Manager (32-bit) can be accessed from the Control Panel (icon view).

Recital 10 introduced the REQUIRE() and REQUIRE_ONCE() statement.

The REQUIRE() statement includes and executes the contents of the specified file at the current program execution level.

When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables, procedures, functions or classes declared in the included file will be available at the current program execution level.

The REQUIRE_ONCE() statement is identical to the REQUIRE() statement except that Recital will check to see if the file as already been included and if so ignore the command.

The full syntax is:
REQUIRE( expC )
REQUIRE_ONCE( expC )

e.g.

REQUIRE_ONCE( "myapp/myglobals.prg" )

sernet.de maintain the latest Samba releases in a yum repository, allowing for an easy and painless install or upgrade of Samba on your yum based Linux distribution.

To install the latest available Samba execute the following commands at the shell:

# cd /etc/yum.repos.d
# wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo
# yum install samba

To upgrade an existing Samba install:

# cd /etc/yum.repos.d
# wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo
## Note: edit sernet-samba.repo and add the line "gpgcheck=false" otherwise 
## it will not install as it is not signed
# yum update samba

Note: These steps will install the very latest build available at sernet.de.
If you require a less bleeding edge version of Samba, use the "tested" repo. This can be found at the following URL: http://ftp.sernet.de/pub/samba/tested/rhel/5

When the node is clicked set editable to false. Set editable to true in the double-click event handler.
// the click event handler 
private function onclick_sourcetree(e:Event):void  {     
    yourTree.editable = false; 
}  

// the doubleclick event handler  
private function ondoubleclick_sourcetree(e:Event):void  {     
    yourTree.editable = true;    
    yourTree.editedItemPosition = {columnIndex:0, rowIndex:sourceTree.selectedIndex};

Recital 10 enhances the APPEND FROM command. The enhancement was added to the following syntax ;
APPEND FROM  <table-name> 
Before when appending into a shared Recital table each new row was locked along with the table header, then unlocked after it was inserted. This operation has now been enhanced to lock the table once, complete inserting all the rows from the table and then unlock the table. The performance of this operation has been increased by using this method. All the database and table constraints are still enforced.

Recital is a dynamic programming language with an embedded high performance database engine particularly well suited for the development and deployment of high transaction throughput applications.

The Recital database engine is not a standalone process with which the application program communicates. Instead, the Recital database is an integral part of any applications developed in Recital. 

Recital implements most of the SQL-99 standard for SQL, but also provides lower level navigational data access for performing high transaction throughput. It is the choice of the application developer whether to use SQL, navigational data access, or a combination of both depending upon the type of application being developed.

The Recital database engine, although operating as an embedded database in the user process, multiple users and other background processes may access the same data concurrently. Read accesses are satisfied in parallel. Recital uses automatic record level locking when performing database updates. This provides for a high degree of database concurrency and superior application performance and differentiates the Recital database from other embeddable databases such as sqlite that locks the entire database file during writing. 

Key features of the Recital scripting language include:

  • High performance database application scripting language
  • Modern object-oriented language features
  • Easy to learn, easy to use
  • Fast, just-in-time compiled
  • Loosely-typed
  • Garbage collected
  • Static arrays, Associative arrays and objects
  • Develop desktop or web applications
  • Cross-platform support
  • Extensive built-in functions
  • Superb built-in SQL command integration
  • Navigational data access for the most demanding applications
  • Scripting  language is upward compatible with FoxPRO

Key features of the Recital database include:

  • A broad subset of ANSI SQL 99, as well as extensions
  • Cross-platform support
  • Stored procedures
  • Triggers
  • Cursors
  • Updatable Views
  • System Tables
  • Query caching
  • Sub-SELECTs (i.e. nested SELECTs)
  • Embedded database library
  • Fault tolerant clustering support
  • Chronological data versioning with database timelines
  • Optional DES3 encrypted data
  • Hot backup
  • Client drivers for ODBC, JDBC and .NET
