This Add-In adds configurable mousewheel support and a few other goodies to the VB IDE. Check it out; download is only 96kB (the best 96 kB you ever downloaded *g*). ## Compile the DLL into your VB folder, use the AddIns manager to add it to the Addins menu, and then restart VB. Read the ReadMe file to learn howto. ## Features: configurable mouse wheel support independent of mouse driver - word autocomplete while you type - autotcomplete for API prototypes, constants and structures - code pane grid at tabstops to facilitate indenting - open all code panes by one mouseclick - function to compare current with previous code - copy facility to paste selected code from other projects - pasteable list of members currently in scope (forms, data and procedures) - easy multiline literal generation and modification - reset function to cancel all alterations in a module without restarting VB.

This is a Form Fader OCX control. Simply stick it on a form, set a few properties, and with two lines of code it will fade-in and fade-out the form smoothly. Also lets you fade the form by setting a fading (opacity) factor between 25% and 100%. Semi-transparent forms can be moved across the background with a realistic transparent effect. The Fader can be compiled separately, of course. This OCX Control is based on code by Ed Preston (and he deserves the votes).

This is an extended timer OCX control permitting Intervals between 10 millisecs and 52 weeks. Although it has quite a few more properties it is still a direct replacement for the standard VB timer control. Check it out, download is only 5kB. Also, it's a good example for beginners who want to learn how to make OCXes.

When you don't know it's there you don't try to find it. This app may be not perfect and I'm sure you can improve it by adding all kinds of gimmicks and a better UI. Anyway, this stegano can hide up to 32k in a picture of 300 by 300 pixels 24 deep with no visible effect ... and it's a little different *smile*

This is a Mouse Wheel .OCX Control which allows you to connect the wheel to any Control which has an hWnd. Wheel scrolling will fire Scroll Events and if Shift or/and Cntl is pressed while scrolling this will also be returned to the client app permitting you to vary scrolling steps or direction. Try it, download is only 6kB.

This article shows the basic concepts of Generic Algorithms. Generic Algorithms (GA) are used to arrive at an optimal solution for problems which cannot be solved by mathmatical rules or formulae. A GA simulates the natural evolution process by selecting and breeding the fittest individuals. According to Darwin's Evolution Theory the "fittest" are those which are best adapted to a competitive and possibly hostile environment...

This AddIn helps you to explore and document your projects. The documentation is incorporated into the source code and may be printed by the Code Formatter Source Print Facility (updated version soon to follow). Compile the DLL into your VB directory and then use the Add-Ins Manager to load the Explorer Add-In into VB. The Splitterbar.OCX (included in the .zip file) is a Control based on a submission by eidos here at PSC. You should copy it to the Windows System Folder and register it using RegSvr32.

This is my attempt to make a chess program. The AI still needs a lot of cooking but the UI is done and it knows most rules (read the attached F.I.D.E. Laws Of Chess). Don't try yet to play against the computer - you will win :-) or worse - the program may crash. I myself am a below-average chess player, so I cannot say anything about the program's strenght or style of play. Time limit does not work properly, so give it say 6 or 12 seconds thinking time, more will make you wait virtually forever... Problem solving works though, I think. Unfortunately PSC does not let me upload Gradient.OCX or MsgHook.OCX, so you will have to delete all references to them. Also the TTF Amaze is not uploadable, just substitute another nice looking font for it. The piece images were copied from RJSoft's Chess Program, with his permission. Enjoy.

Class to encrypt and decrypt a clear text with variable character length encoding. There is no relationship between byte boundaries and encrypted characters, ie an encrypted character may theoretically be anything from 1 to 255 bits long; however this depends on the 'quality' of the key. I am not a cryptoanalyst, but I have a hunch that the variable character length makes this code rather difficult if not impossible to break. One approach may be to scan the encryption for repeating bit-groups and guess the meaning of short groups occuring more frequently than others (like "the", "a", "an" and so forth), or for patterns occuring with a language-specific frequency of vowels and consonants. To forestall that, the encrypting engine uses an initial hash (also derived from the key) and XORs every character with that before encrypting, keeping the result of the XOR for the next character. The decrypting engine of course reverses that process. The encryption engine now features an MD5 message digester which produces a key- and message-dependent binary signature. This signature may be included in the encrypted text to verify it's authenticity. Another advantage of prefixing a message with a signature is the additional scrambling of the encryted text through the previous encrypting of the unpredictable signature (see 'hash' above). This makes the encryption key- and text-dependent, that is, the encryption for a particular character is different when the text is different (apart from being different through hashing). Speed (without debugging) is in excess of 40,000 bytes/sec for encrypting and more than 130,000 bps for decrypting (depending of course on your PC's clock frequency).

This OCX records all mouse and keyboard activities for later playback with original timing. May (but should not) also be used as a stealth keylogger. Try playing back the attached TEST.RCD file :-).

This Add-In creates a Cross Reference Listing for your VB Projects. The X-Ref shows all Public, Global, Friend and Private Data- and Code-Member definitions, where they are defined, their scope (Private / Public / Friend), and what they are: Sub or Function, Property, Event, Variable or Constant. Also shown are all references to these members with ComponentName.MemberName as well as Line and Column numbers. References to Components are also shown. The Cross Reference Listing may be exported to a color-coded RTF file (see screen shot) or to the Clipboard for subsequent pasting into the project or anywhere else. This is the second in the my suite of VB-Add-Ins and goes together with the Code Formatter. It will help you to professionally document your projects in a tidy and consistent way. Compile the DLL into your VB directory and then use the Add-Ins Manager to load the Cross Reference Add-In into VB. Fixed bugs with Resorce Files and Related Documents and added Icons as well as references to Controls, Libraries, and References.

Example to show how to synchronize painting to the Monitor's vertical scan frequency. Painting occurs invisibly during vertical retrace.

This is a 'Finite State Machine' Class to control batch type sequential client programs which fetch records from one or more sequential (normally keyed) data streams and optionally merge them into one stream, and/or exchanges data between matching records. This is done by invoking the discrete procedural steps in a logical sequence (eg FetchNextRecord, GroupHeader, ProcessRecord, GroupFooter etc) which the client program is arranged into. Also supported and invoked are control breaks for outputting subtotals, totals or grand totals; the control breaks are further subdivided into group header and group footer. The class supports a great variety of properties which may come in handy during program execution. Examples for this kind of programs are manifold: Invoicing, batch account-updating from transactions, grouped statistics, budgets and ballances, or report writers with subtotals and totals to name just a few. A comprehensive documentation is included. Compile WinPS 1st, register it if necessary using RegSvr32, and then add a reference to it to TestNewPS (or to any other project that might be using it). Download is 85 kB.

This is an object-oriented Sudoku Solver combining the "cross hatching" strategy with a backtrack algorithm. It solves easy puzzles in about 600 µsecs and really hard ones usually in under 150 msecs (when compiled) on my old AMD Athlon XP1800+. The most evil one I could find is in the screen shot.

This OCX Control is similar to a slider, but has two thumbs which let you define a lower and an upper value. It also features a couple of additional properties which may come in handy. Download is 11.5 kB.
