The response.redirect method is great for moving a user from one page to another. However, it does have one major limitation--you can only use it if absolutely nothing has been written to the page. Sometimes, you actually do want to write something to the page and then redirect it, for example when displaying the status of an operation. In this case, the following JavaRedirect function comes in handy. It requires a Java compatible browser. (Note:this script has been changed to incorporate Lewis Moten's helpful suggestions).

To center all of your forms nicely on the screen, use this as the first line in the Form_Load event--resolution independent. 'note:call this function like this: Center_Form Me

This is a single dimensional Game of Life. The user inputs coordinates for living cells. Using the rules of the Game of Life the program determines if a cell will live or die. It will calculate for any amount of generations. It was developed in MS Visual C++ and uses an input file.

Dumps a string to a file

Transactions are atomic operations that allow you to do multiple operations on a database as one operation. For example, if you were creating a banking application in which you deducted $100 from one account and added it to another account, you wouldn't want the operation to fail right in the middle, because the money would be 'lost'! The solution is to wrap the SQL in a transaction. If the operation is aborted in the middle (the pc gets shut off for example) the database will rollback the changes so that the initial account was never debited the $100. This will make you feel good, especially if its your bank account!

You can use ADO GetRows to output and ADO recordset to an array. This is often useful in n-tier applications when you are moving data between tiers--or if you want to persist your data in another way. http://adozone.cnw.com/default.htm

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

Gravity Simulator that uses the OpenGL Libraries. I used the GLUT event handler interface to control Mouse functions. Found at: http://modzer0.cs.uaf.edu/~hartsock/C_Cpp/OpenGL/Gravity.html

Looking for faster performance? If you have an older database driven ASP app, it probably uses an ODBC DSN in its connection string to reach the database. It probably looks alot like this: "DSN=myDSNName;". If you see this you should immediately upgrade the code to ADO/OLEDB--Microsoft's new standard. Not only will this help you keep the code current, but it will run faster and take up less memory. Below are the connection strings for OLEDB/ADO for both Access and SQL Server--the two most common databases for IIS platforms. If you are using another database, you'll need to consult your db's ADO Provider's documentation for the proper connection string.

Program inputs a string & prints it out backwards to a file. Found at http://users.neca.com/jboxall/ja05002.htm

If you have a large amount of data to give to the user as HTML and this data needs to change once a day then this will speed up the process for the user. The following code will create a file the first time a page is hit for each day. The upside of doing it this way is you have a record of what the use saw on any given day. The downside is the first person takes the performance hit to write the page and you need to check to make sure the user came to this page first. In other words, if they save yesterdays page as a fovorite then they will see old data unless you redirect. I used the month and day to handle this problem. I did not use the year. There are many other ways to handle this problem. http://www.truegeeks.com/asp/mam/osdoc/osframe.asp

Validates whether a given hard/floppy/network drive is valid

You can cause a page to automatically refresh every n seconds using the HTML Meta Refresh. This is great for chat sites, real time monitoring sites or any other site where you must have up to date real-time information. This example will reload itself every 5 seconds and display the current time. Note: Replace the name test3.asp with whatever name you call this script.

This program implements a doubly linked list as a binary search tree and includes functions to: traverse inorder, preorder & postorder, insert and delete a node, search for a node, and count the height of a given leaf.

If you have the need to filter out certain users from your site (hackers, unauthorized personel, etc.) and you know their IP address, you can use this code to do so. It detects the IP address of the current user and based on what that address is, takes action. Of course, you need to replace the IP address and the action in the code with whatever you would like to do...

This program takes the input of a Postcript file, converts the codes in it to plain text which is displayed and re-directable. http://www.cs.latrobe.edu.au/~yuand/ansi_c/index.html

Slowpipe allows the restriction of bandwidth on a modem network connection where a Unix pipe may be used. It was written to address a problem for users of a small network connected to a larger network with a low bandwidth connection. If you use such a connection for both interactive work, and transfer of large files it is possible that using programs such as ftp will consume all available bandwith, making the use of terminal emulators, X-windows etc., near impossible until the transfer is complete. Slowpipe is a simple pipe filter intended to pass all characters through unchanged, but to limit the transfer rate. It does not however have any special knowledge of TCP/IP or other protocols. You may wish to change the packet sizes to multiples of the MTU to your host network for optimal performance if you are able to establish this. The default values though have been found to work satisfactorily on more than one network. The ideal solution is to reconfigure the router to your host network to restrict bandwidth on specific ranges of TCP/IP port numbers though this was not possible in my case. Slowpipe has been tested under Linux and AIX and appears to perform as expected - though I offer no guarantees as this is free software. The user of the software must test their build. No liabilty shall be accepted for failure to perform as expected or consequential damages. I emphasise that this is a simple solution and better solutions may exist - but it solved our problem. http://www.birdsoft.demon.co.uk/proglib/slowpipe.htm
