Elements of Run-Time Error Handling
When you're programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero.

Compact an Access Database with VBS Script
If you have worked with Microsoft Access databases for any length of time, you have no doubt noticed that the mdb file itself tends to bloat as you work with it. Every time you open a form or report in design mode, the mdb file grows. Each time you add records to a table or create a temporary table, the mdb file grows. And contrary to what you might expect, closing or deleting objects and deleting records does not "shrink" the database. Those actions merely make shrinking the mdb file possible. The actual shrinking is done by executing a DAO (Data Access Objects) Method named CompactDatabase.

The release of Access 2007 brings a new file format. The MDB database files we've known for over a decade are now slated to become historical relics.

Reading the Catalog (.psa) in MS Access
I discovered today that the Photoshop Elements 4 catalog is simply a Microsoft Access database with the extension renamed from .mdb to .psa. You can copy your catalog file to another directory (make sure Photoshop is closed first), change the extension to .mdb, double click on it, and voila, MS Access comes up with the catalog open as a database, with 12 tables. Of course, you must have Microsoft Access installed to do this. Since you're working with a COPY of the catalog file, no damage can occur. Now why would you want to do this? Well, I'm not sure yet, but as a software developer, I might think of some interesting reports or searches. You might want to set up a report using SQL capabilities that are more sophisticated than the standard Photoshop searching. It's always nice to have the option...... In the mean time, I need to get back to the tutorials so I can understand white balance, color balance, histograms, and levels better.....

Avoiding divide by zero errors in Access
If you try to divide a number by zero in Access, you receive a #DIV/0 error if you are in a form or report, or a #ERROR error if you are in a query. To avoid a divide by zero error, you can use the IIF function to set the results field to a zero-length string ("") if the divisor in a calculation is zero. You can then search the field for any values that contain a zero-length string and flag the results. The following steps demonstrate this technique by creating a table and a bound form, inserting three text boxes, and entering an expression.

Import an Access 2.0 database into an Access 2007 file
If you use an existing database in the Access 2.0 format (.mdb), you can import tables, queries, and macros from that database into a Microsoft Office Access 2007 database (.accdb).

The following sections in this article explain how to perform each of these tasks. What do you want to do? * Open an Access 2.0 database in Access 2007 * Import data from an Access 2.0 database * Convert an Access 2.0 database by using Access 2003, Access 2002, or Access 2000

Opening a MS Access report
I need to open from VB an existing Access db and preview an existing report. The db is password protected. I have added a MS Access 9.0 Object Library reference to the project. The code above open Access, maximize it, then prompts user for the database password, and after the input open effectively the report preview. The problem is the OpenCurrentDatabase method doesn't allow to set a db password, like the connection string parameter [Database Password=mypassword;]. Many people in other forums say that I can simply add the password parameter to the 'AccRep.OpenCurrentDatabase dbname, False' instruction, but is not true: if I put down 'AccRep.OpenCurrentDatabase dbname, False, "Password=mypassword" ' (or "PWD=mypassword", or "Database Password=mypassword", or many other experimental strings), it returns a 450 error "Invalid number of arguments" when run.

Connecting to an Access Database using C#
This may seem like a common task, and it is, however I found it ridiculously difficult to learn how to do it.

Run-time error on form
I have set up a database for monitoring users of our financial system. with the user ID being numeric, and everything has worked fine. Recently the administrators of the database have asked me to alter the database to accept alphanumeric ID's. After changing the data type to text, certain of my forms that use a filter are producing the following error message. "Run-time error '2501' The ApplyFilter action was cancelled. You used a method of the DoCmd object to carry out an action in Visual Basic, but then clicked Cancel in a dialog box." I know that the error message is due to the change in data types, because when I delete the alphanumeric data and change the type back, the forms work again.
