Display A File Image on a Form

If you are planning on storing images in your application (such as pictures of products) I would highly recommend just storing the path to the image and not the actual image in your Access DB. I have written a number of successful applications where the images are stored in a regular file directory, and only the path is recorded in Access. This method works well and keeps the size of the database small.

The code that follows illustrates a very simple test program that asks the user to enter a path to an image, such as C:\Images\MyImage.jpg. Then, the form will request the image to be displayed. Because forms are private, I use the convenience of putting variables I want to pass to the form in a Global variable visible to all forms, objects and modules. The sample code in the program below follows this logic:

(1) When the user starts the Access DB, the AutoExec macro executes
(2) First, AutoExec runs the code that initializes the global variable I use
(3) Next, AutoExec runs code that displays an input box asking the user for a file path to an image
(4) When the user enters the path, the module opens the form
(5) The form has a Form_Open event that uses the global path to the image to call the actual module that displays the image
