This is a very easy way to add a Tree View (like the VB Control) in your html page. With 1 function, add TreeViews with or without checkboxs and links. If you like it, vote for it ! Simon

This simulates a tab control in pure DHTML, using cascading stylesheets and VBScript to do the job. Mind you the VBScript code can easily be changed to JavaScript. With this, you can develop your own web application without haveing to use an Active-X control.

How do I prevent a form from being submitted, until all required fields are correct ? Only one field is used in the example. Every time the user clicks the OK button, the onClick event fires. If it passes the test the form will submit, else the focus will be placed on the textbox, an alert will appear and the submit button will be disabled, which stops the submit process. The onMouseMove event is used to enable the button again. I just added the error handling code in case an error comes up. It is actually not necessary, you can just enable the button again. I use the onControlSelect event on the submit button, because sometimes after being disabled, the button looks like it is embedded in the page. The above event fixes it. The above can be applied to multiple textboxes, and multiple conditions and arguments can be used. It saves time and space as the validation is done on the current page, before the form is submitted. Otherwise the user has to go through the laborious task of clicking the back button on the posting page to be redirected to the previous page, and fix a simple mistake. I've had comments that the JavaScript return false statement is a better solution. Unfortunately the return false; statement doesn't seem to work when you are using frames. I hope you find this usefull !.

I have always loved the HierMenus found at Web Reference but I wanted to be able to grab information from a database to fill the nodes. Well one weekend and a case of Mountain Dew later, a totally reusable HierMenu from DB to Menu system. There are some things you might notice: 1: Lack of More then useful comments. Reason: you will have to be familiar enough with Java, DHTML and ASP to be able to really understand this. 2: GetRows() was used so if you are going to have lots of null Parent Nodes you might what to consider using MoveFirst, MoveNext Methods. Reason: GetRows() is way faster. 3: HierMenus is a Product if you use it give credit were credit is due. I did not in any way create the HierMenus they were already made, all I did was find a way to provide Data from a DB to the menus. Please Vote For Me!

This code will generate a HTML-code with a VbScript MsgBox, after setting a few things like Message title, icon or when the MsgBox should be invoked. Just execute this HTML file to generate a MsgBox (beginners) or look at the source to see the way I let had the MsgBox created by the form.

Updated 3/23/2001 11:17 PM !!!!!!!!!!!!!!!!!!!!! This code will allow you to build an input form "on the fly" from a database. Instead of creating and hard coding the same old input form you can automatically build your form based on column names or values in your database! Just added is another page that will submit your data to your database "on the fly", truely making the process of creating web based entry forms DYNAMIC!!!!!!!! Now whenever you have to alter your input forms you just have to change your SELECT statement, no more HTML!! Please vote for this code if you find it useful, and feel free to send me any questions you have regarding the code. Thank you.

This DHTML Dynamic Menu slides in from the sided. Using Javascript that is embedded in 2 ASP include files. The menu is Database driven.

This is a message umm center hehe, Let your users send messages to other uses, NOT a CHAT it is more of an email client but sends them to other members your site, This version is very basic and will need to be modified in order to work properly, view the readme.txt file for more info. The next version will be great, I figured gotta have a simple basic one for the first version and then come out with a better more advanced version next time around right? yeah ok.. View it here http://65.4.131.57/Justin/messageCenter/Script/message_center.asp

This article explains how to use Simplewire's platform to embed SMS wireless messaging to cell phones and pagers into your applications in ASP. This will allow your application to send information to mobile users throughout the world. I hope this helps a lot of you who are trying to developer wireless applications.

This code passes all form variables by creating hidden copies of every form variable that was passed to it. This is great for gathering information over multiples forms (i.e. Order Processing).

Multi-function form for basic navigation, table editing, and recordset paging. This example includes code to dynamically build an SQL UPDATE command based on changed items on the current record. http://adozone.cnw.com/default.htm

Demostrates how you can easily create a cool menu using the default filters which are part of internet explorer. You can easily modify the code to use it for your own menus.

A 30 minutes e-book reading program to replace Adobe Acrobat Reader. This is a simple one. Thanks to J. Kelly Jr. for his GREAT File Binder submission.

This is an example of how to use the Winsock control to download a file from an Web Server(HTTP Server). It is real simple to do, but it took me a few hours to figure out. I hope everyone likes it. I decided to do this, because I haven't seen much like it on Planet Source Code. I've updated it, fixing a couple bugs.

The code is essentially a catalging program with a variety of output formats. The source code is continually updated and a compiled version is available at http://www.octa4.net.au/tonywaite/vb/vb.html Let me know what you think?

A Memory Mapped File resides in virtual memory from the moment it is opened until it is closed. This makes access to it very fast, in fact read and write merely consist of data moves in memory. All parts of the file are accessible by means of a zero based offset and the length of the data chunks you can transfer is only limited by the file size itself. The system will swap out and in pages of virtual memory as necessary. Only when you close the file the data are "lazily" written to disc, and the Physical Write Operations are limited to the altered memory pages. When you open an MMF you are required to supply an estimate of how large the file is gonna be. Any reasonable estimate will be fine, however, you cannot exceed this estimate, ie you can't extend a file while it is open, but you can truncate the file size to the actual size used when you close it. You can extend an existing file by giving the appropriate estimate when you open it and truncating it to the larger size when closing. MMFs are byte oriented and that requires a bit of understanding the data types which VB uses and how they are represented physically. The class contains tools however to handle the different aspects.

After looking all over on PSC i was unable to find Short, Simple and Clean code to get the target path of a window's shortcut (.lnk) file, so here is an easier way.

This code is based on the Windows 95, Windows 98, and Windows 98 Second Edition glitch in file viewing. Be very careful with this tool for if you lock the folder that contains the program, the program will not run. For example if this program is in your C:\Program Files\Lock\ folder and you lock Program Files the program will not run. There a few safety features. First you need to create a shortcut to the EXE (when you compile it or just rem the line in the frmLoad Form_Load section that checks for the Command$). Create a shortcut to the EXE and give it a command line of shortcut. (If you edit the properties of the shortcut file and find the location of the program. at the end of that add "shortcut" without quotes). Next your mouse needs to be in the upper left hand corner of the screen at co-ordinates 0,0. I would suggest giving the shortcut a "hot key" or using the keyboard to open it. Without the command line "shortcut" and the mouse being in the upper left hand corner of the screen the password box will not appear. Now the initial password (default) is "maxx" without the quotes. Once in the program you can change the password. You can always delete the string from the registry and the password will default back to maxx. The file/folder locking feature is due to windows 98se and belows glitch. DOS can read characters windows can not. So by going in dos and using an ALT code to rename a file/folder it will rename it. However windows will not be able to read the alt code and will give the file/folder an underscore. You will not be able to open/explore or delete the locked folder/file. In my program I use the alt code of alt+0254 or chr$(254). If for some reason you mess up a file or folder and the program can not rename it or if you locked the program itself you can manually fix it. Either load a dos prompt or restart in dos. The command used to rename files in DOS is REN or RENAME. The format for ren or rename is the same and goes as follows. REN (Source Path and File Name) (New File Name) for example: REN C:\Clever.txt Smart.txt this will rename the file Clever to Smart. To get rid of the lock you will need to use alt plus the number-pad. Lets say clever was locked. You would need to do this REN C:\Clever(hold alt and press 0254).txt Clever.txt When you hold alt and press 0254 it will insert a box, that is the alt code. When you hit enter the file/folder should be renamed and everything should be okay.

I made Auto File Copy to do a auto backup of a folder and subfolders twice a day to me USB drive, and only copy the new and modified files. All setting is stored in the registry. At 16:55 you can backup 5 GIG’s and only copy the files that have changes. Enjoy and please leave comments and a vote if you like it. Thanks to the two submissions that I borrowed code from (mentioned in code) The zip has been replaced with corrected code.
