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

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!

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

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

I've recently taken over a project from someone else, and I've been left with code that has few naming conventions and a lot of bugs. I often find myself stepping through code wanting to check the value of a field. Unfortunately, I don't know the field's name-it could be Name, UserName, NameUser, txtName, and so on. It's a real pain to stop the program, click on the control in question, press [F4], get the control name, start the program again, and return to the point in the code where I was before. Here's a handy trick to get the control name right away. by Jeff Brown; Jeff.Brown@piog.com; Pioneering Management Corporation

Visual Basic 5.0 allows you to use UserControls to create ActiveX controls in your projects. The following code snippet does two things: It gets a reference to the form in which a UserControl is placed, and it gets a reference to that control on the form. by David Mendlen

Prompting the User for a Directory in Win95. Windows' common dialogs are great if you want the user to select a file, but what if you want them to select a directory? Call the following function, which relies on Win32's new SHBrowseForFolder function:

Here's a simple application to function like the Windows Task Manager...

Welcome fellow programmers!! This is part one of the course which will show you the basics of programming C++ from scratch using the any platform. If you already know how to use the C++ already, you might want to read later lessons when available. So, lets begin. Found at http://pa.pulze.com/

Welcome fellow programmers to our third lesson in a long series on the road to programming C++. This articles explains do, while, #include, and #define. (from http://pa.pulze.com/)

The goal of the present HTTPFS project is to enable access to remote files, directories, and other containers (e.g., structured text documents, OS tables) through an HTTP pipe. HTTPFS system permits retrieval, creation and modification of these resources as if they were regular files and directories on a local filesystem. The remote host can be any UNIX or Win9x/WinNT box that is capable of running a Perl CGI script, and accessible either directly or via a web proxy or a gateway. HTTPFS runs entirely in user space. The current implementation fully supports reading as well as creating, writing, appending, and truncating of files on a remote HTTP host. HTTPFS provides an isolation level for concurrent file access stronger than the one mandated by POSIX file system semantics, closer to that of AFS. Both a programmatic interface with familiar open(), read(), write(), close(), etc. calls, and an interactive interface, via the popular Midnight Commander file browser, are provided. HTTPFS offers a glimpse of one of Plan9's jewels -- a uniform file-centric naming of disparate resources -- but without Plan9. This file system showcases HTTP, which is capable of far more than merely carrying web pages. HTTP can aspire to be the kingpin protocol that glues computing, storage, etc. resources together to form a distributed system -- the role 9P plays in Plan9. HTTPFS articles argue that unlike a popular catch phrase, it is the OS itself that is the browser. The client framework has been tested on GNU/Linux 2.0.36, HP-UX 10.xx, Sun Ultra-2/Solaris 2.6. An HTTPFS server will run on anything that can execute a Perl CGI script -- and this really means anything. The server has been tested on HP-UX B10.xx with a Netscape Server/1.12, Sun/Solaris 2.6 and Linux with an Apache/1.3.x server, and with Microsoft-IIS on WinNT 4.0.

DtWinVer is a routine which provides a comprehensive method to determine which OS the program that calls it is running on. All methods it uses are fully documented on various articles on the MSDN CD. The routine provides the emulated OS aswell as the underlying OS. e.g. to a Dos program Windows 95 looks like MS-DOS 7.0.
