Free spreadsheet component delphi software for windows

a free open source component for Delphi 2.0 and C++ Builder 1.0 TSuperList was designed to be a free open source component for Delphi 2.0 and C++ Builder 1.0 (it will work in later versions, just build a package) that incorporates better control over a standard TListbox control.
TSuperList incorporates a panel with a plus and minus button for addition to and deletion from a listbox. Input and editing is made through a built in InputBox, so it requires no coding to add, delete, or edit items in the listbox. The majority of the testing has been done in C++ Builder because that is the environment that I work in most. I wrote it in Delphi so that it reaches a greater number of people.
System requirements:
- Delphi 2.0 and C++ Builder 1.0

FlagHint gives you a component for Delphi 6,7.
The package includes:
- License agreement;
- Manual in HTML file (is what you currently read);
- Source code of the sample project;
- FREE ? full source code of the component (FlagHint.pas).
Conceptually, MCFlagHint is a combination of the Windows popup hints, "Whats this?" context popup help, and our needs to quickly show and hide diagnostic messages.
MCFlagHint simplifies the users life:
- User has no need to search the screen for the problematic control ? the component will set focus to it, graphically point to it and display the message near to it.
- User has no need to perform any special actions to discard this message from the screen. When he understand the message then he just continue with his task and the message will disappear.
- Programmer may use only single function call, DoFlagHint, to display the message (see the Example below).
Main features:
- MCFlagHint is displayed as modeless window (not modal or dialog) and can be discarded due to any user acivity (clicking mouse or pressing keyboard) excepting the mouse movements.
- Only one MCFlagHint window can be visible at the same moment.

Delphi component pack that contains most of things ive been using to develop the applications you see on this page (also this http server). As far as I know the support is working quite nicely.
API Component pack contains several different components for different purposes that has been developed during my own needs in applications and some of some one others need; however this is the direction in future also. All components are improved by the requests of users and also users can improve them.
Just only thing I want is that every improvement is sent to me also, just to know whats happening and through this Im able to add those features into the package available here.
One thing that i would like in exchange is that you should tell these component origin somehow in the source and rest of this legal things you can find at top of each component
If you like this component pack, please donate to support its improvement.

GemBox.Spreadsheet - provides easy, elegant and high performance way to create, convert, write to and read from Excel files GemBox.Spreadsheet is a very useful .NET component which provides easy, elegant and high performance way to create, convert, write to and read from native Microsoft Excel files (XLS files in BIFF format or CSV files in text format) without the need for Microsoft Excel on either the developer or client machines.
With Microsoft Office installed on most business desktops it is tempting to use Microsoft Excel object for XLS file reading / writing.
Performance. In the case of desktop application, you dont want your user to wait 20 seconds for every single report. In the case of web application, you want your server to simultaneously support as much users as possible. Our test programs generate single XLS file with 200 rows and 100 columns of tabular data. Half of the values are strings and half are numbers, with 50% of cells having some cell style applied (font size and border).
100% managed code. Many of the competing products (and actually Microsoft Excel object) are old COM components with .NET RCW (Runtime Callable Wrapper). That brings many performance and interoperability disadvantages as every method call you make goes through the wrapper until it reaches C++ code. On the other hand, our GemBox.Spreadsheet component is 100% managed, written entirely in C# and designed to support both Visual Basic .NET and C# in equal manner.
Clean and easy to use API. GemBox.Spreadsheet is a designed and developed to conform to Microsoft standards for .NET libraries.
Version restrictions:
- Maximum number of rows per sheet is 150.
- Maximum number of sheets per workbook is 5.
