The best way to flood fill is to use ExtFloodFill. Absolutely vital functionality for graphics applications. Trouble is it doesn't lend itself for use with .NET. Your only alternative to ExtFloodFill is to use recursive routines to scan an image and change pixels colors appropriately. This can be quite inefficient and take an unreasonable amount of time to perform. There was quite a good example last month here on PSC and I've seen a good one by Bob Powel. Searching on the intenet for ExtFloodFill and .NET will return many examples of people wanting to use ExtFloodFill but I have yet to see a solution. So here it is.
Some useful routines for those just starting out in VB.NET. File handling routines, embedded resources, graphics, system icons, ownerdrawn listboxes, serialization and much more. Presented in a format familiar to those who have used my VB 6 beginners toolboxes. Source code relevent to the current tab appearing in a text box ready for copying/saving. Included in this solution are 3 other projects I did when I first obtained Microsoft Visual Studio .NET 2003. They are 3 simple clones of Calculator, Notepad and Minesweeper. I find that one of the best learning exercises you can do is to write clones of existing software. The coding strategies employed in an application are not always obvious until you come to duplicate the software yourself.
This demo shows some of the capabilities of editing RichTextBox tags to achieve very fast global formatting. Great for Syntax Highlighting etc.
This demo shows in the simplest possible code, the basics of image editing. It is intended for the novice but others may find it useful in optimising or simplifying their code. Whilst it is in no way a full blown editor, it may provide a basis from which to learn. If you want an example of a more advanced image editor I suggest you look at "Bobo Image Workshop" which is found at: http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=21482&lngWId=1
Need to test installs on different operating systems? Need a new operating system fast? Infected by virus?...Read this - it may help.
Here is the third part of my Web Browser Tricks This time as a Web Browser(nearly). What's here ? - a nearly exact clone of Internet Explorer's Favorites menu, autocomplete Address combo, menu's enabled/disabled by the Webbrowser, text resizing including identification of current size, progress bar in the Statusbar, plus all the standard WebBrowser stuff.
I keep reading requests for RichtextBox code on PSC so I decided to upload one of my templates with a few added features. Nothing that special here really - basic RichtextBox functioality. The RichtextBox is pretty good at what it does though ! This example demonstrates : Find and Replace, Infinite Undo/Redo, Using .tmp files, HighLighting selected words, Inserting Images, Inserting text at a set location with different Fonts, Common Editing Functions, Shrinking a path to a desired length, Creating your own light-weight Wizard. This is not meant to be a complete application merely a demonstation of some techniques. All error messages and bugs are provided entirely free of charge. Feel free to use any of the code or errors as you wish - MS wrote the control - I've just shown how you might use it. It's capable of more than I've shown here.
This Example Application Demonstates : Enable/Disable Forward and back Buttons, Standard Navigation Buttons, Cut/Copy/Paste/SelectAll edit functions, Auto-Complete Address Box, Saving and Loading MRUs, Avoiding duplicates in Combo/List boxes, The 'about:' Navigation method, Opening and Saving Web Pages, Using Explorers' Find File or Folder Dialog, Finding text on current page, Sizing text on Web pages, Showing a progress guage, Showing Status text, Creating HTML pages at runtime. If I get some interest via the way of votes I'll put up some more
Search a directory for files containing a specified string and return a list of such files. Once again, I've uploaded this in response to a quetion posted in the Discussion Forum.
Shows how to add items to a listview and then save those items to either an INI file or to Registry. Once saved you can then load the data back into the listview.
Another addition to my WebBrowser tricks. This one shows how to access SHDOCVW.dll so that with one line of code you can 1.Bring up Internet Explorers' Add to Favorites Dialog 2.Convert Netscape Bookmarks to Favorites 3.Convert Favorites to a Netscape Bookmark file. 4.Download files without IE throwing up its' dialog. Also I threw a couple of simple Windows based procedures... 1.Show Windows File Property Dialog 2.Show Windows Find file Dialog 3.A method of hiding the Cursor system wide.
This is in response to a 'Request for Code' in the discussion forum. It's similar to lots of other submissions of address book style apps. It shows how to create and access a database without any data controls - just by referencing 'Microsoft DAO 3.6 Object Library'. Purely an introduction to databases - nothing more. A simple address book in 160 lines of code, easily expanded, with lots of comments to guide a beginner through the code.
This little App will allow you to edit or create menus in VB6 Forms. It removes the limitations of the number of nested submenus allowable in the VB6 menu editor on which it is based. New forms can be created with menus in place. It can be used to extract menu structures from one form and place it in another. You can save menu structures as templates for later use. It has only been tested in VB6. Use it as you would the Menu Editor in VB6 with the exception of the Open/Save operations. As with all my submissions, bugs and errors are provided completely free of charge.
Updated version - removed many bugs and errors. Thanks for the feedback and interest shown by all those who emailed me. It helped greatly.

In response to requests for more samples here is Volume 2. This collection includes the use of scrollbars, listboxes and the treeview. Move listitems up or down in a listbox, remove duplicates etc. The treeview example demonstrates a fully functioning 'Favorites bar' for a Web browser application using Internet explorers favorites - add links, add new folders, rename, delete etc. Also included is a KeyCode giver, a picture resizer, and just for fun a random mousemover. Code for each function appear in a textbox ready to copy into your project. I hope this is of some help to people beginning VB. Good luck.
This is an app I wrote early last year to see how far I could go with VBs' graphic editing capabilities. It's still a work in progress and could do with a rewrite. After Stu Lishman uploaded his latest version of Stu Paint I added Twain support, thanks Stu. The program was thrown together quickly but is none the less complete and working, with only one or two minor bugs. It does most things Paint Shop Pro will do. I have a version with layers that works quite well but is less complete than this version. It demonstrates cut, copy, paste, selection, freehand selection, shapes, multiple clipboards, color handling, effects, filter browser, inserting text, magnifying, rotation, inversion, MDI window control, toolwindows, MRU lists, Temp files, Undo/Redo, buttonising etc.etc. Some of the effects are modified versions of code downloaded from PSC. Unlike most of my other submissions there is very little commenting of code - it's too big now and I've forgotten more of the functions than I remember. For the more advanced coders however it should not be too difficult to follow. It was an experiment however, so there is some duplication of both code and controls, with heaps of room for optimising.
Threw this together to answer a group of questions in the Discussion forum. It is intended to help those just starting VB. It demostrates string manipulation, file handling, simple navigation, reading and writing to files. It includes four example apps that include menus, window handling, file properties and a basic text editor. Code for each function appear in a textbox ready to copy into your project. I hope this is of some help to people beginning VB. Good luck.
If you are writing an Image Editor or your app opens picture files you need this. Just like the big boys you can now show a preview of images right there in the CommonDialog window. Very easy to use. Add a module and a small form to your project and call with a single line of code.
Allows you to alter the text on messagebox buttons. Easy to use and call. Just add a module to your project and call with a single line of code in a similar manner to the standard Msgbox call. Commented code and extensive example usage.
This module provides a Win2K interface to the Browse for Folder under Win95/98. This is not an update to my earlier submissions but a complete rewrite using pure API. With Win2K MS introduced a new DLL (SHELL32.DLL Version 5.0) which includes a better Edit box, Popup menu and a New Folder button. With this module you can achieve the same result (except the Popup menu) using the old DLL (SHELL32.DLL Version 4.71) as used by Win 95/98. Additionally you can add a checkbox, customise captions for Titlebar, OK button, Cancel button, New Folder button. You can also resize the Browse for folder window. Additionally you can choose to open the dialog double size or full screen. All the usual features are present, such as include files, start at special folders etc. You can select between the old style Editbox or the Win2K style editbox (Much better I think.) Why bother? - Not everyone is running Win2K. Very easy to call. Heavily commented and includes complete sample usage. Please vote if you find this useful.
