11/10/2003: To celebrate my mother's birthday (to whom I shall dedicate this update to) I've decided to post a new version of the code. As posted in the recent article, all of the bugs and features that you have suggested have been implemented. Thank you very much for your comments! If you find any new bugs, please let me know! This article will teach you about a big secret of the NT File System (NTFS): Alternate Data Streams. First off, a brief history about ADS will be offered, followed by practical applications of data streams, with examples. Finally, explanations on how to protect yourself from the dangers (and what they are) of ADS. Full source code is included as well as a GUI for scanning your disk for ADS, as well as editing and viewing them (or creating new ones). As a bonus, there are two versions, one in pure API, and one using VB controls. Finally, you can integrate this app in a VBS script, with very little modification, for server maintenance.

Hi everyone, Included in the ZIP file is a new version of the NTFS Alternate Data Stream code. It fixes all the bugs listed below, and add new features. All of these have been kindly given as suggestions from everyone on the site, and I wish to thank you! If you'd like to read the original article and vote on it (if you haven't seen it already), it's located at: http://www.planetsourcecode.com/vb/default.asp?lngCId=47299&lngWId=1

I haven't seen this on PSC using the filesystem object or a collection. very neat and fast since you don't need to go through it twice to redim an array. the only slow down with this code is the print statement.

After hunting for this functionality since I started using VB, I've finally figured out how to *quickly* read the last few lines in a file. This function fills a dynamic array with the last X number of lines in a file you specify. I use it to monitor apachewin32 logs on another server. This is much faster than using 'line input'. I know there may be more optimized ways of doing this, I just thought I should get it out there.

Just learning how to manipulate the ListView Control and thought I would pass this along. Might do more controls later on if response is good.

This code shows how to keep the current row position highlighted after a sort is done by a user on a DataGridView by clicking one of the column headers.

Shows how to get the former and current value in the current cell of a DataGridView along with customizing the current DataGridView context menu.

This project demonstrates a very simple usage implementing a DataGridViewImageColumn. The project has been kept simple to allow a good learning experience. Nothing is needed outside of Visual Studio, all data needed is created via an array for the demo.

Just a simple program which uses the FileSystemObject and Recursion to output a complete directory/file structure of your computer to a file. I was originally gonna use this as a sort of snooping thing a while ago, you could run it on someones computer, and then read the text file to see what they had on their computers. The text files come out quite large, but when zipped up they're usually only about 50k. Uses a good example of recursion.

Yet another word processor. Shows the basics of centering text, left/right justify, choose font, font color, cut, copy, paste, undo, select all... Keeps track of if your current file has been saved or not, basic word processor. I got bored.

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.

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.

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.

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.

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.

Adds a touch of professionalism to your project. Just like VB IDE. One tab has the common dialog, the other tab shows recent files, their path and their icon in a listview. Can obviously be adapted to show images, provide different settings and options to the user as to how they wish to open a file. Included : Standard EXE project, UserControl Project and test project, OCX Project and a test project for the OCX. Demonstrates saving/loading listview to registry, getting file icons for use in a listview, how to build your own commondialog controls, controlling other apps windows.

With this ocx you can access INI Files from vbScript, VisualBasic, ASP (maybe). Read, Write Keys, Read all KeyNames of Sections, Read all Sections of an INI file. Delete a Key, Delete Section ..... The Readme.htm shows how it works. This Upload has now also include a Demo for Visaul Basic and vbScript. Also included is the code for the OCX, it's written with VB6 and it's a good demo for the how to create an ocx file. Please vote for this code
