The cell can have a sequence of expressions and it only show the result of the last expression.
For example:

{ a1:=sum(A2:A11); a2:=if(a1>10; “grande”; “pequeno”) }

In this case, if this expression was introduced in the cell B2, the cell B2 will have the same value with cell A2.

Addition of new features to the new formulae language, such as the assignment of a value to a given cell.

Example: # A2:=sum(A3:A10)

sums A3 to A10 and assigns this value to A2

Exporting data to a selected database using HSQLDB

Mechanism to find all the instances of cleansheets with active share on the same network

Importing data from a selected database using HSQLDB

In this task, the application will synchronize between application and database, using an internal engine.

If a merge error was detected, the user must choose what content will be updated.

It must exist on a application a file template with the structure of the same file.

The language must support a new type of loop, do while

This security system should be based in a password that is sent from the client to the server. This password should be encrypted.

Adding a brand new formulae language, starting with the character #. This new language should support all the features provided by the current language.

On application's menu must exist a option to select import or export data to a database

Improve the existing export to database feature by allowing the user to choose from adding or replacing the data to an existing table. It should be allowed to set a specific column combination as the table's primary key.

Sharing a user-defined area with third-party application.

Changes in the cells must be immediately visible in another running instances of the application like auto-refresh for all instances on the same connection

The application should support cicles. For example:

whiledo{ a1>10; b2:=b2+a1; a1:=b1+1 }

The first expression is the stop cicle condition, and the folowing expressions are the execution of the iteration. The result of the while is the result of the last expression executed.

For each iteration, the while must test the first condition and then execute the iteration.

Import the content of a DB table to a CleanSheets sheet. This process should employ threads in order to increase performance.

Choose the destination machine that receives incoming data
