Delphi Onderdils The Delphi Resources

Data compression is generally achieved by studying the data and looking for redundant
patterns and probabilities. This is a basic concern of information theory, a branch of
mathematics that was founded by Claude Shannon at Bell Labs. Information theory can be
used to determine the entropy, or information content, of a message. The entropy of a
message describes the minimum amount of space that must be used to fully describe the
message. In general, if the information content of a message is smaller than the existing
representation of the message, the message is compressible.

Abbrevia is a set of components that allows you to add file archiving and data compression
to your applications. Using Abbrevia, your application can organize data (by grouping files
into an archive) and save disk space (by compressing the data).
A file archive is a collection of related files that are maintained as a single unit. Common
archive procedures include browsing, adding, extracting, and deleting files from the archive.
Data compression is a process that manipulates a collection of data and produces a
representation of that data in less space. There are two types of compression: lossless
compression and lossy compression. Data compressed using a lossless compression
technique can be completely recovered with 100% accuracy. Important examples of lossless
compression include the compression used in backup and restore tools, disk compression
tools such as Stacker, the Microsoft CAB format, and the PKZIP tools developed by
PKWare, Inc. Lossy compression techniques allow for some loss of accuracy. Lossy
compression is often used for compressing graphic, voice, or video data. JPEG is an example
of a lossy compression technique.

Delphi is multi purposes programming, sometime I use it to open internet banking such as KLIKBCA, Bank Mandiri and Bank BNI. We can open website from delphi, by use component TwebBrowser. This example I use delphi 7

OK.. next we go to the source

As we know that delphi has many message box(s), like showmessage, messagedlg ect. By defult we get font message in black color with style regular.  All style message are in dialogs unit. so if we want to enhance we have to change this unit as we want.

for example like this picture :

next…on

This example is how I look for nohp in a pulse transaction on the server. using tedit to find data on the next grid.
In the event of a change in tedit, the text will be searched to the next column of the grid. Column Nohp located at index 6. by looping from the first line to last line , it will seek the edit value in the column specified. If there is data that is similar or the text containing the data will be displayed in nextgrid

This is example fill next grid with data using addoquery and microsoft Access database.

The first time you must add columns to  nextgrid by double click the component, and then choose type column of  next grid wicth do you want :

• Tnxtextcolunn
• Tnxnumbercolumn
• TnxImagecolumn
• ect

Next Grid is Grid component from Berg Software, we can acces cells like field, such as :;

begin
 edit1.text:=gridtrx.Cell[6, i].AsString;
 edit2.text:=inttostr(gridtrx.Cell[6, i].Asinteger);
end;

NextGrid is a powerful Delphi/CBuilder Grid. It is very easy to use it in design-time (with using intuitive Columns Editor) and in run-time.

NextGrid have much more features than standard Grid, attractive look (Windows Vista & XP themes support), it is extremely fast (quick sorting, data manipulation, drawing…)
