This Program generates ADO code and SQL Statements without the use of an ADO Data Control. It is available as a stand alone executable or as a VB-6.0 AddIn.

This code is used to search for clients in an access 2000 database using ADO and a parameter query. In our database we have roughly 20000 records to search and it still finds them very quickly.

Asynchronous Database Processing via Active EXE - When processing thousands of requests for a multi-user real-time application, you cannot afford to wait for the relatively slow database processing to occur. Here's the scenario: You have 1000 people already online and playing your multi-user game, and 10 people in the process of logging on right now. What do you do? You could process the logons right now, searching through thousands of user records, to load up their information - but then the game would appear to 'hang' for everyone already playing, waaaay bogus. You could process only 1 person at a time, in the main processing loop - that's better, but will add unnecessary slowdown to your program. What if you could log on the person in a BACKGROUND process, which wouldn't slow down the existing users? Ooh yeah. Or better yet, hand the request off to a machine across the network, dedicated to database processing? NOW we're talking! :-) You can do this easily, using Visual Basic ActiveX EXE's. Have fun with it!

A valuable tool in your programming toolkit. Use this routine for when an Access table goes bad. Often when this happens conventional INSERT or APPEND queries or cut/paste techniques don't work for backing up your table. This is a routine for copying data from one table to another table, field by field. As the information is processed, bad data fields are skipped over and logged in a log file. Only good data is deposited in the target table. **re-uploaded/Corrected II**

** Release 3 ** New cTREEVIEW features: Flat border; IsChildNode; CopyNode with cancel option; Cut Icon state. ADO example supporting: Load on demand; Find First/ Next/ Previous; Label Edit; Drag'n'Drop; Node & TreeView context menus; node specific Open/Closed/Drag icons. ADO Example now supports: New Nodes/Records can be added; copy treeview node(s); Cut/Copy/Paste through right-click context menu; and functions are now benchmarked with results displayed. ** Release 2 ** cTREEVIEW class features: Scroll treeview Up/ Down/ PageUp/ PageDown/ Home/ End using code; Dragging with auto-scrolling (not supported by Microsoft in the TreeView control); NodeFirstViewable; & NodeLastViewable. ADO Example fixes: Find Next/Previous didn't work if branches already loaded. cTREEVIEW class fixes: correct node drag icon displayed. cTreeview features include: fast clear a treeview; extended Add/Rename/Delete nodes; copy & move nodes through code &/or Drag'n'Drop including parent nodes onto child nodes (not normally possible!); find node using text and (optionally) key properties; check if a node is a parent of another; checks if a node is a root node; a safe get parent node text; right-click context menu (before/after click event); collapse/expand all nodes; collape/expand all child nodes; enable/disable redraw. This example shows how to:- work with multiple tables of data and load data on demand. As a bonus, I've included cDB class that encapsulates working with an Access Database using ADO. All code is heavily commented. If there are any routines that you feel are missing or code/bug-fixes that you wish to contribute, then please let me know and I'll add them in. *** Latest version can be found here:- http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=37553&lngWId=1 ***

It lets the user compact any database including password protected ones. And it also over writes the old one. Uses no controls only API.

I wanted a way to send messages to the users who are in an access database. This code opens and reads the ldb file for the database (that you specify on the form), reads the user names and sends a message....all without API calls. You can do a lot more with this obviously (I trimmed it down a lot for this forum). You will need one text box for the source of the ldb file (named txtLocation), one command button, and one text box for your message (named txtMsg).

It is a Good example for those who want to connect the Database with ado, Visual basic Suggestion and Comments are Welcome

The code demonstrates 3 common combobox tasks: 1.) Filling a cbo with a recordset 2.) Setting the cbo Text to a recordset field using a numeric rst field 3.) Setting the cbo Text to a recordset field using a non-numeric rst field

This simple code allows to make an auto-filled textbox (like an adress box in IE). This example uses an DataEnvironment connection, but it can be easy used in any other cases.

Converts the timestamp data type of SQL server into a string that is then suitable for use in a where clause

Shows you how you can use a progress bar while reading an MS Access database. This example uses two progress bars, one for reading each table, and the other for reading the entire database. Programmed using VB6, if you have a previous version of VB you can add the frm file to a new project (However, I have not tried this myself)

Learn how to incorporate Access Databases into your Visual Basic project! Add, delete, edit, and refresh all records in the NWIND.mdb database. Then, display the data from that database in a datagrid and a 3D bar/line/pie graph! Comes with a downloadable example application! Please rate and leave feedback!

A simple example on how to add/Delete a DSN to the ODBC of a Windows Operating system. Completely commented.

This article shows how to store and retrieve images from a database in a fairly simple way.

A perfect example of using an Access database. With these example, you can add, delete, moving in the database. All validation is done. Use PageUp and PageDown to seek records. Very nice interface. Reusable code. All code is commented. Simply the best example ever on planet-source code about database management.

Here it comes again with a cool interface a compact one(like the msoffice taskbar) and a full one(see screenshot).It has more number of functions than you can imagine.An image viewer(not a simple one).A database using Msaccess.A calculator.A Phone Dialer.An Inbuilt internet browser.Calender,time date(you can even set the system time).Play movies or MP3's as you work.It took me many days to complete.PLEASE VOTE FOR IT.visit www.gauravcreations.com for many more cool programs .

This Project Allows the end user to access a MSAccess Database through a Client Winsock application, without having any Data Access Components installed on the local machine. This also allows fast read/write access through modem, or a dead slow computer. The client app sends the server a few strings and then generates an SQL statement, and then does all the hard work and sends back the results to the client.

This VBA Automation demonstration assumes that Microsoft Excel 97 and Access 97 are installed. It hasn't been tested yet with Office 2000. My work required an Excel application that could generate charts based on information in Access. After searching PSC I came upon a great example by Joe Miquel which I've built upon. Once you've started the application all you will need to do is Click on the Excel Button on the Access Form. Feel free to expand and to innovate the code. Many thanks to PSC and to Joe Miguel for a great idea. Hope you like it.
