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.

This is in response to many requests for "removing duplicates in a listbox" in the discussion forum. Using the API is almost always faster than using VB. I'm unaware of any examples here on PSC of using the API for removing dupes - I may be wrong. Either way this is a very efficient way of accomplishing this task. No need to vote - code couldn't be much simpler than this! Feel free to improve upon the code yourself. As usual all bugs come entirely free of charge.

If you've ever tried to use the standard Toolbar customise feature then you will know it doesn't work. This is a documented bug - visit MS and do a search. They offer some solutions, but these only partially rectify the problems. The problems involve an inabilty to reliably save the configuration of the Toolbar and a failure to display unused items in the left hand selection Listview. My fix Scrap the feature entirely - uncheck AllowCustimize checkbox in properties Replace the dialog with a clone form Power the function with a simple class

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.

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.

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.

This is a quick demo of thievery. It demonstrates how to steal the Treeview from the BrowseForFolder dialog for use by us poor VB coders.

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.

More examples for Beginners by MrBobo. This little demo demostrates the use of Drive boxes, Dir boxes and Filelistboxes. To give the example some purpose it allows you to safely bulk change the extensions of files in a selected directory. To do this safely you need to quickly parse filepaths and include error handling to avoid overwriting. The demo includes an example of a 'Desktop' and 'Up one level' button in its' browse function, get special folders, enumerating all filetypes from the registry and a simple auto-complete function for comboboxes. Includes an interesting function - Safesave - which appends a number to a filename if the file is found to already exist.

Browse for Folders Dialog with 'Create New Folder' button and 'Include Subfolders' checkbox. CommonDialog with image previews. Both these controls are updated versions of functionality included in some of my previous submissions. Now Win 2K compliant. Please vote if you like it.

Another example for Beginners from MrBobo. This example program shows how to communicate between instances of your application. Lets say your application is assosiated to a filetype. The user clicks on such a file and an instance of your application is launched. But what if you want to load the file in the existing instance - not the new one ? There are many examples of how to achieve similar results on PSC. This method is designed for reliability and ease of use with a minimum of code to implement.

Syntax coloring, advanced selection routines and Highlighting. Highlighting using the Richtextbox control is awkward. Whilst there are a host of Selection properties there is no Highlight property we can access from VB. We just have to parse the RTF code.

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.

If your sick of typing in the same old menus over and over then try this out. Extracts menu data from VB Forms and Usercontrols and allows inserting these menus into other VB Forms/Usercontrols or saving as a template for later use. Whilst its a useful little programming tool in itself, it was written to demonstrate string parsing and filetype creation and association including, Explorer context menus.

A practical demonstration of using classes to optimise your applications. Correctly written classes make your code re-usable, faster, more reliable and memory efficient. They also speed devolopment time, make debugging easier and can be placed in DLL's making them accessable from multiple applications simultaneously As time goes by they become even better because each time you use the same class in different apps, any bugs that do show up get removed for future apps as well.

A reasonably complete clone of Regedit.exe with a few added extras. All coders should be familiar with the layout and usage of the Registry If you're not then here it is on a plate !

A scientific calculator. Written as Usercontrol, very lightweight, very easy to call. Demonstrates trigonometrical and logarithmic functions, each with just a line or 2 of code. Great to learn from.

Disable *.vbw files from running when you click on a VB6 Project file(*.vbp or *.vbg) in Explorer. Simple registry function to avoid malicious vbw files activating. No timers, no overhead, run once and your protected.

Handling File Paths. The VB programmer should try to use the API wherever possible. It is usually faster and more memory efficient than most VB methods. We should also make use of .RES files rather than hard coding to reduce the amount of memory consumed by our applications. This little demo attempts to illustrate these concepts in the simplest possible way.

File Association can be tricky and there are some rather blunt instruments being applied in some examples of Association both on this site and elsewhere on the web. This demo shows how to Associate your App to a file extension and safely return Association to the previously Associated program if desired. Lots of comments, easy to call, with the absolute minimum of code required to do the job. Prompted by more than one question in the Discussion Forum.
