Professional Excel Templates
Current Web Services provide simple information sources that you can easily incorporate into applications, such as stock quotes, weather forecasts, and sports scores. As the demand for access to business logic over the web increases, companies are finding ways of providing their customers with a class of applications to analyze and aggregate information. If a customer now keeps a Microsoft Excel spreadsheet in which they manually summarize their financial information, such as stock portfolio, 401 (k), bank account, and loan information, in the future, a Web Service will consolidate and continuously update this information for display by Excel or on a personal web site or digital assistant. Although much of this information is available through the web today, a Web Service will simplify access and consolidation and will ensure greater reliability.
For example, Delphi comes with several ActiveX controls, including charting, spreadsheet, and graphics controls. You can add these controls to the Component palette in the IDE, and then use them like any standard VCL component, dropping them on forms and setting their properties using the Object Inspector.
Data sharing methods such as Dynamic Data Exchange (DDE) and Object Linking and Embedding (OLE) are even more powerful. With them, you can automatically reflect changes in one data file to many users using many instances of your application. You can create a front end that integrates the data and functionality of a word processor, spreadsheet, and database all in one application. You can even run and control other applications from within your application.
Any form can be implemented as a multiple document interface (MDI) or single document interface (SDI) form. In an MDI application, more than one document or child window can be opened within a single parent window. This is common in applications such as spreadsheets or word processors. An SDI application, in contrast, normally contains a single document view. To make your form an SDI application, set the FormStyle property of your Form object to fsNormal.
Multiple Document Interface is a means for applications to simultaneously open and display two or more files, within the same application. For example, you might use MDI to allow a word-processing application to open and display several documents simultaneously and provide the user with a way to quickly switch among those open documents. Likewise, you might use MDI to create a spreadsheet application that enables users to have several spreadsheets open at once, for example to compare sales figures or interest charges.
I've written a program, called DBOffice, which uses predefined server components to send a table to Word and to Excel. In both cases, you can use the application object, the document worksheet object, or a combination of the two. There are other specialized components, for tasks such as handling Excel charts, but this example will suffice to introduce use of the built-in Office components.
For example, suppose a salesman on the road has been keeping his sales records on his laptop computer in a spreadsheet application. When he gets back to the office, one way he could enter these records into the SALES table would be to export the information to a text file and then import the data into the database through an external table. So, in this example, you do not need to perform step one, because the SALES table already exists in the database.
In the case of Excel, I've used a slightly different approach and worked with the application object. The code creates a new Excel spreadsheet, fills it with a database table, and formats the result. It uses an Excel internal object, Range, which is not to be confused with a similar
To please the end user, we delivered a native Windows application - providing a crisp and responsive graphical interface. Because it's a native Windows technology, ASTA programs can take advantage of existing operating system benefits and future benefits as well. If it can be done in Windows, it can be done in ASTA. That includes sharing data with other programs (word processors, spreadsheets, browsers). With Kylix, this applies to Linux as well.
DDE is good for exchanging distinct text strings. If all you want to know is the bottom line of a profits spreadsheet, it makes sense to link the cell that contains the bottom line to a Delphi DDE client application. Then you could output the data in an edit box or label. DDE protects the data in the spreadsheet by not allowing the user to activate and edit the spreadsheet from your client application. OLE is able to exchange more complex information than DDE, such as sounds and documents. Control transfers to the OLE server application when you activate an object in your OLE container, so the user can access all the functionality of the server application from within your container application. The server does all the processing and you don't have to program your container to edit the OLE object. This would be good if you wanted to allow your users to modify the profits spreadsheet from within your application.
The DirectX development team's goal was to create a low-level architecture that would provide developers with the hardware control they need at the speed they demanded, while still retaining Windows' device-independent benefits. This was to be accomplished without imposing a restrictive high-level design architecture. First and foremost, DirectX had to be fast in order to allow game developers to create the high-performance, adrenaline-pumping action games demanded by hard-core game players. DirectX applications must also coexist peacefully with other Windows applications, such as spreadsheets and word processors. Therefore, DirectX promises three things to developers fast execution, minimal style restraints, and a level of abstraction that will provide benefits from future hardware.
To illustrate this type of object usage, consider the following scenario Frequently, information managers will create a spreadsheet in a spreadsheet program and use the contents of that spreadsheet in a word processing program in order to present a report. They will usually opt to link the data to the spreadsheet when pasting from the Clipboard or importing the spreadsheet into the word processor. That way, when changes are made to the spreadsheet, the word processing document is automatically updated to reflect the new data. In the same way, changes made to a base form will automatically be reflected in all forms inherited from the base form. Use the Inherit option when you want to have several forms based on a common form that might change at some point. Any changes in the base form will be reflected in all inherited forms.
Active Documents (previously referred to as OLE documents) are a set of COM services that support linking and embedding, drag-and-drop, and visual editing. Active Documents can seamlessly incorporate data or objects of different formats, such as sound clips, spreadsheets, text, and bitmaps.
Any form you design can be implemented in your application as a Multiple Document Interface (MDI) or Single Document Interface (SDI) form. In an MDI application, more than one document or child window can be opened within a single parent window. This is common in applications such as spreadsheets or word processors. An SDI application, by contrast, normally contains a single document view.

What can you use a grid for Building a spreadsheet is probably the first idea that comes to mind, but that's probably a little too complex for an example. I've decided to use the StringGrid control in a program that shows the fonts installed in the system and the DrawGrid control in a program that emulates the MineSweeper game.
Where Can I Download Vertex42 The Excel Nexus
To be honest there is no free download for Vertex42 The Excel Nexus. You have to pay for it, just as you have to pay for a car, or for a pair of shoes, or to have your house painted.
