Shows how ADO technology connects globaly. Also shows how to integrate ADO Data Control and the Data Grid. This project uses the phonebook concept to show these concepts.
Class object that can be compiled or copied and pasted into your application that will dynamically create MS Access ODBC DSN's for you.
Here are two functions that will allow you to read and write a Large Binary Object (BLOB) to and from a database. This could be used to store and retrieve images, documents, etc inside the database it self. This is great for those of use that have a lot of Binary files around that we want to keep in a central place that can be backed up and protected with the same security that a database offers. This code will work with *ANY* database that ADO can connect to.
how to use SQL to extract desired information from a database
I did not write this code by myself , i had found it at http://support.microsoft.com/support/kb/articles/Q246/3/35.ASP With this code you can transfer the contents of an ADO recordset to a Microsoft Excel worksheet by automating Excel , this code will work only with Excel 2000 or 2002 , for Execl 97 use my previous examples, or just look at this examlpe for basic knowledge at the IF statement.
This code will let you repair and compact an Access 97 or 2000 (haven't tested on other versions yet) database. Using JRO, when you call the CompactDatabase function, it automatically repairs the database first. You must have a reference to Microsoft Jet And Replication Objects x.x Library in your project. Also, where I have a DoEvents in the code, there really should be some routine that checks to see when the file is actually deleted. I've tested this on databases that are about 5 megs in size with no problem. If anyone has any ideas (maybe a routine that checks to see when the file is unlocked or deleted), let me now. Thanks and enjoy!!
Ok, and now that you have finished your Super Multiuser Access application ,would you like to know who is logged on??? well, here is the answer and the code to do it. don´t forget to rate if you like it.

Since MS-Access doesn't support accent insensitive queries by itself (MS SQL Server does as far as I know), I had to create a function that would fix the problem. With this function, it is possible to turn any SQL query into an accent insensitive query. With a few little modifications, it works great with ASP too!

How do you avoid the "Invalid use of null" error when reading null values from a database?If you try to retrieve a null value (empty field) from a database, you will get the error: "Invalid use of Null". Here is one way to get around this problem: ..
I used this class for well over 2 years. It is easy. It comes with a simple program that show you how to use it. I am sure that once you will know how it is working that you will adopt it.
PLEASE FIND A BUG!!!!!!!!!!!!!!!!!!!!!!! I DARE YA! I fixed the one that was found when you type somthign in the main interface when you have an empty dat file then click in the search list box. See if u can find more. By the way PLEASE VOTE!!!! thanx ;-) Well finally after heaps of emails complaining about the source safe protection HERE you go!! a non protected version, as you will see the code is a shocka, it really needs arrays. It reads everything off a text file to save HD Space. I am going to make an Access version prolly in about a month or so, well maybe longer coz i am doing my HSC. Anyway, this prog provides a simple to use, yet useful phonebook/contacts program. I have gone through and sussed out pretty much every bug I could think of, see if you can find any! I DARE YA TO FIND A BUG!!!!!!!!!!!!!!!!!!!!!!
