The TDbSearch object (not packaged as a Delphi component) from Aaron Castro allows Paradox-like searching on any field in a TDataSource, without the need for the field to be indexed. |
|
Components for a StatusBar (see WARNING below), general system information and file information for EXE, DLL and VBX files. |
|
Component for doing Paradox-like Locate/Locate Next for Delphi applications. When the dbLocate search engine is called a modal dialog box pops up to allow the user to select a fieldname and search criteria (exact, wildcard or range matches). The dialog stays topmost until exited. Similar idea to TDbSearch (see DBSRCH01 archive above), perhaps more comprehensive? Both have their uses. |
|
Multi-line hint component from Martin Brutsch. Simple and easy, no more horible long one-line hints! |
|

Includes support for printing graphic objects. |
|
Enhanced TEdit-type control which can make a field a required field and/or control valid keystrokes by means of a valid character list. This version can beep when an invalid key is pressed. |
|

|
A collection of shareware Delphi components from Stefan Boether. Includes: TStopWatch for elapsed time measurement; TRemember for saving and restoring position, size etc of a form for the next time your app is loaded; TScreenSaver (obvious!); DbStatus to indicate current status of a datasource (edit, insert, browse etc); TDbRemember ù like TRemember but for controls linked to a datasource; TMemTable to allow creating of in-memory database tables; TDbFilter for easy database filtering. |
WARNING!
Both the LCSCMP02.ZIP and TPACK.ZIP archives included on this disk contain
components called TStatusBar. If you try to install both then you will
get an error when rebuilding the COMPLIB.DCL and you will end up with NO
components at all on your component palette! (a good reason to have a backup
copy of COMPLIB.DCL...!).
There are several ways round this:
1. Have different versions of COMPLIB.DCL, one with the TPACK components and another with the LCSCMP02 components. Problem with this is that there are lots of good things in TPack which you might want to use with_ the LCSCMP02 TStatusBar (which does actually have more functionality).
2. Amend the source code (and forms donÆt forget!) in TPACK so that its TStatusBar is called something else. This is not an option with LCSCMP02 as source is not provided.
3. Amend the REGTPACK.PAS file in TPACK, which is used to register the TPACK components into COMPLIB.DCL and thus onto the component palette, so that TStatusBar is commented out (line 197, in the Register procedure).
Sample component from a set (available for purchase from Gerald Ltd) which demonstrates direct access to IBM AS400. |

|
TTUtility is a Delphi component that implements the functionality in BorlandÆs TUtility.DLL, the same DLL that comes with Paradox for Windows. The primary purpose of this component is to give the Delphi or Paradox developer an easy to implement tool for validating and fixing corrupt Paradox tables from inside delivered applications. The TUtility DLL on which this component is based will work on Paradox tables up to and including level 5 tables. Plus a bonus component to check and regenerate out of date Indexes. |
TComponentCollector by Patrik Wang. Have you ever been frustrated by all those non-visual component icons cluttering up your forms? Well worry no more: just drop one of these componenents onto a form and it will act as a container for all your other non-visual components, leaving your form clear in design mode. The ôcollectedö components are still easily selectable via the right button click pop-up menu so you can edit their properties. |

|
HighLightIt is a smart tool that links into the Windows 95 TaskBar and helps documentation your source code by looking for normal text on the clipboard and converting it to RTF format before pasting it back onto the clipboard complete with bold keywords and italic comments. This can then be pasted into your favourite wordprocessing application as formatted source code. Currently supports Pascal/Delphi, C/C++, Java, Basic and Delphi Forms. From Stefan Boether at Fabula Software. This is a demo version. |
|
This directory contains fully operational 16- and 32-bit copies of the TMarquisLights component. The screen shot does not do the component justice as the lights appear to rotate (even at design time). |
|
Rubicon for Delphi (16- and 32-bit) is a set of components which support word indexing and searching of database tables. For my testing, I used my DTopics database and the results (as can been seen from the screen shots) were very good. You do need to persevere if you are trying the supplied demo though, this feels a bit flaky with error messages coming up before files are created for the first time, etc. From Tamarack Associates. |
|
Issue 6 (Feb96) included an early version of Julian ZierschÆs rich text controls as æwork in progressÆ. ItÆs come a long way since then and the version on this monthÆs disk is 1.7. Full Delphi 1 & Delphi 2 support is provided. TWPRichText allows you to edit formatted text of almost any length. For graphics, simply insert a bitmap or metafile object. When designing your program you can input text which contains various formats. Also supported are alignment, paragraph spacing, borders, font selection, colors, etc. It is easy to add fast mailmerge to a project. You have only to put some æInsertPointsÆ into the RTF text and you can now fill in the data in an event handler. It is possible to merge Memo fields, because Carriage Returns are translated into NewLines. Tables are now supported. A Cell can contain a paragraph with 1 to 50 lines. TDBWPRichText is a data-aware version of TWPRichText. TWPRichTextLabel Displays formatted text which cannot be scrolled or edited, but the text can be made transparent. TWPRtfStorage stores formatted text (usually during designing) and assigns it to any visual RTF component if desired. TWPToolBar controls one or more TWPRichText or TDBWPRichText components. |
An updated version (2.5) of the TCompress compression components from Peter Hyde. New features include: key-based protection for compressed data, creation of self-extracting archives, plus the ability to store and extract compressed data as project or DLL resources. Also included is TSegCompress from Ken McClain which allows segmented archives, eg to span across a number of floppy disks. |
|
This is a small utility that may be added to the Delphi 1 and/or Delphi 2 Tools menu to help with finding the correct glyph for your next TBitBtn. The glyphs are displayed on buttons, showing the number of images stored. |
|
HeapTrace enables debugging of heap memory use in Delphi applications. It helps you get rid of memory leaks, dangling pointers and memory overruns in your programs, providing optional logging of all memory allocations, de-allocations and errors, as well as being extremely easy to use: Just include HeapTrac as the first unit in your project fileÆs uses clause. The demo version on diskette is the 32 bit version and is limited by the memory amount the target program is allocated. There is a more recent version HT32121.EXE available on CompuServe (GO BDELPHI32) and on the Web (www.xcity.com/modelistica/heaptrace): I tested this, but ran into compatibility problems with my Windows NT3.51 system which is still under investigation. |
|

|
DateGen is a free utility from Bob Swart used to generate a file called COMPDATE.PAS to be placed on your library path. You just add two lines to AUTOEXEC.BAT and then whenever you reboot, two new versions of the file will be generated (for Delphi 1 and 2). If you add the unit CompDate to the uses clause of your Delphi projects then you can use the constant CompiledAt to indicate when your project was last compiled. |
|
The BisonWare file parser component adds powerful parsing capabilities to your Delphi applications. Both ASCII text files and text strings in memory may be parsed, with just a few lines of code. |
|
This contains an un-registered version of the Shazam end-user report component. Basically, Shazam is a run-time SQL generator that allows you to provide an end-user reporting function within your program by dropping a component on the form and adding a single line of code. |
|

This file contains 16bit and 32bit versions of a replacement property editor for TSpeedButton and TBitBtn glyphs. Enhanced functionality includes a glyph viewer, a favourites list and an image editor. Installing is very simple: copy the GLPROPED.DLL to DELPHI\BIN and register the GLPROPED.DCU component as usual. The supplied components are fully functional but do have an initial nag screen which may be disabled by supplying your registration number. You may register via Compuserve SWREG (13229) for US$12. |
|
There is no Borland supplied component that wraps the Win95 PageSetupDlg common dialog API function. This file contains the source of a Delphi 2 component that rectifies this omission and comes with an example of use. |
|
Solver is a Delphi (16bit and 32bit) component which finds the solutions to non-linear simultaneous equations or calculates the values of expressions. The user can enter equations or expressions as a string at run time. Your code can then display or plot the calculated values.Extend the capabilities of Solver by defining the syntax and behaviour of your own Delphi functions. |
The TAnimatedSymbol component supports Win95 style animations (like files flying from one folder to the other) using simple AVI files. The file also contains a simple tool (with source) that allows you to compile a set of bitmaps into an AVI file. |
|
The DB-Analyzer is a little tool which allows you to display and save the structure and data of BDE-32-registered databases. The tool allows you to retrieve your actual database design in HTML or SQL format. The latter generates INSERTS for all tables so that you can easily move your database from one DBMS to another. |
|
The TDBVEdit component is an alternative to the standard TDBEdit object that includes an additional OnValidate event. This fires before leaving the field, in contrast with the standard OnExit event which is executed after leaving the field. This makes data validation much easier to program as it prevents the focus problems associated with displaying errors while preventing the user from leaving the control until it contains valid data. Of course, you may want to bypass the checks you have in the OnValidate handler if, for instance, the user presses a cancel button. TDBVEdit has a CtlNames property which you may populate with a list of the controls that suppress the event if they are next to get focus. |
|
This sounds like an odd utility at first, but is actually very useful and definitely time-saving! In a nutshell, the program will convert almost any Delphi form with components into a procedure that can be called to create the form ôon the flyö without the need for a separate DFM file. |
|
The PopupBox component is a Delphi 2 control that combines an edit box with a listbox. PopupBox looks like a ComboBox by default, but you have much more flexibility in look and behaviour by setting properties. Beside PopupBox there is also a data-aware descendant of PopupBox control included in this package, called DBPopupBox. It allows the user to change the value of the field of the current record in a dataset either by selecting an item from a list or by typing in the edit box part of the control. A third component, called PopupBoxDates, is a special PopupBox. This control shows all dates between a specific beginning date and an end date. |
|
TValidator is a non visual component for Delphi 2.0 which simplifies implementation of validation for shareware programs. If you protect your programs via a registration name and number, this component is for you! |
|
A freeware utility, written by Per Larsen, which will unload modules from memory. Particularly useful for when Delphi crashes. Will remember what modules you elect to unload between sessions so that you wonÆt have to repeatedly select the modules that the Delphi IDE (or whatever) has left in memory. |
Animated Sprites is a set of two Delphi 2 components: TSpritesPad and TASprite. With these two components you can add sprites to your applications and/or games. Both components are visual and include procedures and functions which will give you full control of your sprites. You can detect collisions between sprites or move the background with just few lines of code. Put SpritesPad and ASprite on a form, assign them values, call the UpdateAll or UpdateSprites functions with TTImer, and you have an animated sprite on screen. SpriteMaker software for building sprites from bitmaps is also included. |
|
These two files offer alternative ways of obtaining the fashionable CoolButton functionality for Delphi 1 and Delphi 2 apps. TExplorerButton is freeware and is the most versatile (complicated?) of the two and does mimic the buttons from you know who. Basically works like a transparent Tspeedbutton (including the grouping logic) with TPopMenu attachment and background drawing properties. TFlyOverButton costs $10 for the source, and is a much simpler beast with far fewer properties. It supplies the TPopMenu attachment and the CoolButton display methods, but not the grouping facilities. If you are interested in being æcoolÆ, I suggest you try both components to see which one suits you best. |
|
PAS2HTML is a conversion program (with 16bit and 32bit versions) which translates Delphi Pascal source files into HTML format with Delphi compatible syntax highlighting. This makes it very easy to publish source code on the Web in a clear way. If you have every tried to create a HTML page containing highlighted source you know how much work this can be. PAS2HTML has an extra feature: It is also available as a CGI application, so you donÆt need to convert all your PAS file before you publish them on the WEB (or on your companyÆs intranet). You can use the 32-bit version of the program on any compatible WWW server (like MicrosoftÆs IIS). |
|
This is a demonstration version of Speed Daemon v1.2 for Delphi, a profiling utility that supports Delphi 1 and Delphi2. This Demo serves as an evaluation copy of the commercial version. It includes most of the functionality of the commercial version, but for only two Delphi Demo projects: THRDDEMO.DPR (Delphi 2) and STOCKS.DPR (Delphi 1). If you have not installed the Demo programs from your Delphi CD, you will need to do this first before you can run the Speed Daemon demo. The commercial version costs $149, has the help features enabled and allows you to profile any Delphi 1.0 or 2.0 project. |
|
SpaceMaker is a small Delphi add-on that, when properly installed, turns your object inspector and/or Delphi into ôAuto-Hideö windows. They will react much like the Windows 95 or NT 4.0 taskbar! I was very sceptical about this product at first because I really hate auto-hide for the taskbar, but I was very pleasantly surprised.

Part of the xTools suite from Stefan Boether, this is a Delphi 2.0 component that extends the TUpDown component from the Win95 palette. It adds the behaviour to drag the updown position of that control with the mouse. Now the user can easy use the mouse to set the position with a smart drag operation in the middle of the button. During the mouse operation the mouse cursor switch to a horizontal or vertical splitter shape. The operation ends if the user release the mouse button. |
The TFXCards component has been designed to be used in the development of card games. TFXCards is not just another card component, it has built-in special effects that will give your games that ôlittle something extra.ö For example, instead of instantly changing a cardÆs value from, say, the ten-of-spades to the jack-of-hearts, wouldnÆt it be much cooler to flip the card image, or perhaps fade one image into another! Well, TFXCards has several built-in methods that will do these things for you. But thatÆs not all, TFXCards has several other cool effects, like card color inversion, animated translation and built-in sound effects. TFXCards has two different deck styles to choose from: a Standard deck and a Custom deck. The Custom deck, and over 14 card back images, are all new, never before seen artwork, that will set your games apart from all the rest. |

The Delphi 3 compiled version of the Ziegler Collection. This file breaks my size rule for inclusion on the diskette by being over 500Kb, but it contains so many goodies that I just had to include it. One word of warning though before installing: if you have a component called Animate, remove it from your component palette and PAS/DCU files from your path first, else you will go through the same hassles as I did. After installing as per the instructions, the first thing you notice is an additional entry in the Delphi IDE Components menu: ZieglerSoft Library-Search-Path-Extender. Clicking this generates a dialog box (illustrated: note the useful triangular buttons) which has proved to be a brilliant way of maintaining the Delphi Library Path. The Ziegler Collection also contains 42 components and 26 functions/procedures. Some are shown in the screen shots, but I suggest you have a look in the included help file for details of everything available. |
