This code will create a database and produce a document that contains all of the table and field parameters. This is the first part of a series that will show how to use a single program to dynamically deliver any type of interactive multimedia courseware whether it's Computer Based Training(CBT), Computer Assisted Instruction(CAI), or an Adaptive Evaluation and Examination System(AEES) with all of the information being read from a database.

Basically I took the most common database commands and wrapped them into an Active X DLL. Step 1 – Compile the DLL Step 2 – Open and run the “Test” program Hope this helps some of you newbies

This code will allow you to populate DBGrids and other bound data controls using a Data Control, SQL, and an ODBC DataBase.

The project has two forms. Both displays charts using mschart control for a data from access table. One form displays a chart(2D BAR) for the first record of the table. The second form displays a chart(2D BAR) for a set of records. 1.Both the charts displays legends. 2.Both the charts displays titles for X and Y axis. 3.Both the charts accepts a title to the chart at the desired location. 4.Both the charts displays data values at the desired location above the data points of each item. 5.Above all, the second chart(in the second form)displays bars in the charts dynamically as and when records are entered. i.e., if there are five records, five sets of data series will be automatically displayed. 6. Column labels and row labels are named in the code itself. 7. Filling colors to each data series is mentioned in the code. To summarize, a customized graphical representation of a set of data from an access table can be created by any user.

My third submission to Planet Source Code demonstrates how to use ADO and the Datagrid Control together. One neat feature of this app is the use of a horizontal scroll bar to move through records. I haven't thoroughly tested this app so don't be surprised if you find a couple bugs. If you're new to ADO or even a novice I'm sure you'll find something useful in this app. Please vote and give me some feedback!

Have you ever wanted data to be returned a page at a time? For example the data you requested returns 200 rows and you want to return them to the user 1 page at a time? Well now you can! PS!! Do not forget to rate this software. This results in more code!! Thanks.

This class will let you create ADO recordsets on the Fly - Without a database.Once I wrote a dll that had to return an ADO recordset, but as I had no connection to a database, I had to write this class and I felt like sharing it.This class will worl only under VB6

This is a veeeery simple code to make one autocomplete textbox that gets the first letters you typed and searches for the most similar word from a table and then completes the rest. No API Calls, No Classes, Only few lines of code in 2 events...Simply save it as a module (.bas) and add it to your project

This is an example of a DAO DATABASE CONNECTION PROGRAM Este es un ejemplo de un PROGRAMA DE CONECTIVIDAD A UN BASE DE DATOS POR DAO. This program contains an english part, for those that speak english. Este programa contiene un parte en español, para aquellos que hablan español.

A simple project which can serve as a good example for use of crystal reports,DAO and dynamic control arrey.

Contains One Class clsCompareDB and a Demo project. Purpose: To compare two MS Access tables in different databases. The code alse demonstrates: ADO Technique to retrieve the Table names from an MS Access Database using the Connection Object OpenSchema Method. ADO Techniques for using a recordset to retrieve Column Name, DataType and Size. This class came as a result of MS Access being so easy to Change. Before I Joined Tier Technology training I was employed by the United States Navy (DP1). Our Managers decided that the MDB file should not be locked in any way. We were requested to train the users what they can do and what they shouldn't do. This gave no Guarantee though. We had several programs that required that several tables in different databases (IE MDB's for different years) be identical in every way. The procedures in question copied information of processed information by Column Index (Column position) or by using For Each (which also relied on the Column Position). Recently I needed this technique to do some debugging on an application I wrote for Tier Technology Training. So I dug this program up. Converted it to a Class and converted all DAO code to ADO code (Just to see if I could do this). Also this allowed this class to easily be converted for use with other databases (Other than MS Access). Author: Joel Isenstadt(iteachvb@aol.com).

Last code of mine was about quering tables and i used a little bit SQL In this small code i will try to explain SQLText string. How is it created and working? This series will continue under this name !Lets Create Database Applications-V?

For beginner database programmers.

Second code for managing database series. Querying with SQL and basic dictionary application. Enjoy it.

This code will save and retrieve bitmap graphic files from an OLE Object field inan Access 97 database. The same principle applies to earlier versions of Access/VB, but I haven't tested them. You'll need to use the appropriate DAO library. Let me know if you find a way to save other graphic formats.

This sample project will show you how to easily structure a query to a DataBase. The sample uses the NWND.MDB that ship by default with VB5 and 6 and demonstrates on a searchform how to search on a text from a textBox and use the different comparison operators like =,>,LIKE, etc. NOTE: This is for total newbies that have a hard time figuring this out. I myself had a hardtime in the doc to get an easy explanation on this. Cheers, and hope you enjoy.

This program converts any SQL Server table into a CSV text file.

Imports ASCII text databases in any format, to Microsoft Access format. Very nice GUI. You will need to find a "Replace" function from Planet Source Code and paste it in... only if you are using VB4 or VB5.

What you can do is hook up to a database, and with the use of a timer control, you can make a list of any/all records you want in a database. You can use an SQL statement (in the code already) to find a certain part of a string. The return results are any record that contains that particular string in it. Then with the click of a button it will go through each record found and make a list of them. For example, For a spell checker, I took a database that contained over 5,500 words. It went through that database in a little over 5 minutes to get every word made into a list. Very good ideas can come from this, have fun with it!

This code is an update of my previous submission. I put in code to convert database info to a comma delimited file, and to fill a listbox with data. I'm still working on it to do more things (SQL searches, etc.), and I'm going to do images,and things like that. I'm also going to improve the conversion to HTML to make it even better. Have fun with it!
