Have you ever had the need to create hypertext documents within your app? How about providing HTML editing support? Or even just providing HTML viewing within an existing app? Well, there are help authoring tools like Help Magician, and hypertext text controls like AllText - but neither approach has the ability to view or create HTML documents.

Enter Component Graphic's ErgoPack. ErgoPack 3.0 includes Grid, Tree, Tab, and Plan controls, as well as an HTML control, but clearly the HTML control is the "king" of this particular castle.

CGHTML

CGHTML is a relatively full featured HTML browser component, supporting GIF and BMP images in the VBX; and JPEG, TIFF, PCX, Targa, GIF & EPS in the OCX versions. Functionality, which is unfortunately yet to arrive, includes support for Tables, Client-Side image mapping, and other enhanced tags. Nevertheless, you can create pretty decent web pages using just the CGHTML sample app - which amounts to not much more than a textbox for input, and a side-by-side preview supplied by CGHTML.

HTMLs created using CGHTML are fully useable for implementation in your web page. Although this control provides a solution only to a locally based hypertext system, Component Graphics are planning to add HTTP and FTP protocol support by working with a few protocol control vendors, such as Distinct Corporation, to come out with some demos of how to hook up a CGHTML browser to the Internet when desired.

CGGrid

CGGrid's most striking feature is its bound mode using a direct connection to any ODBC datasource. This connection is possible by either running the ODBC Wizard, which is built into the control, or by defining the ODBC properties at design time or runtime.

CGGrid offers many styles that can be defined at the column level allowing different fonts, colour, and alignment settings. CGGrid includes several column types such as in-cell checkbox, drop down, User Draw, and supports multiple vertical and horizontal splits.

CGTree

Providing all the standard functionality of Microsoft's outline control, the CGTree control also provides static and dynamic modes: Static mode storing the entire data structure for the tree on execution of your application, or Dynamic mode storing first level nodes, and only the storing the data structure when a lower level node is expanded resulting in quicker data access. DragDrop capabilities are also available.

CGErgoPlan

If you are looking for scheduling controls, the CGErgoPlan consists of three related controls, all of which are data aware and editable at runtime.

• The MultiView Control allows you to display any number of days, and allows you to define your own interval of time. Time segments can be scheduled by left clicking and dragging a schedule item into a cell; or by left clicking on the planner at the start-time position, and dragging the cursor to the end-time position. These user defined segments can also be modified by dragging the edges of a segment to cover a larger time interval.
• The MonthView Control is a one month calendar view with incremental day and year boxes.
• The DateSelect Control is a calendar style combobox allowing the user to graphically select a day and return the predefined Date format.

CGErgoTAB

A tab control is what you need? Look no further. CGErgoTAB is a very fast, simple tab control containing Win95 tab styles. Along with orientation styles, and picture and text justification, the feature that really sets it apart from other tab controls is its easily definable per tab backcolour and forecolour properties.
