#REPORT DATAB BAR ACCESS HOW TO#

The steps in the following sections explain how to add and manage attachments. You can manipulate attachments programmatically. Then you can edit the attachments and make sure that you like your changes before you save those changes back to your database. You can save the attached files to locations on your hard disk drive or on the network. If the program that was used to create the attached file is installed on your computer, you can open and edit the attached files in that program. For example, JPEG files are compressed by the graphics program that created them, so Access does not compress them. When you open the Attachments dialog box from a report, you can save the attached files only to another location.Īccess will compress your attached files unless those files are compressed natively. When you open the Attachments dialog box from a table or a form, you can add, remove, edit, and save attached files. When you scroll through the attachments, the control renders the image and displays the program icons for the document and the drawing. For example, let's say you have a photo, a resume, and a Visio drawing attached to a record. If you want to manage attachments from a form or view attachments from a report, you add the attachment control to the form or report and then bind the control to the underlying attachment table field.īy default, the attachment control renders images and displays the program icon that corresponds to other file types. You can open the dialog box directly from the attachment field in a table by double-clicking the field. You use the Attachments dialog box to add, edit, and manage attachments. Individual files cannot exceed 256 megabytes in size.

You can attach a maximum of two gigabytes of data (the maximum size for an Access database). For example, you can store images, and files created with word processing and spreadsheet programs. You can store multiple files in a single record. After you set the data type to Attachments, you cannot change it. You must create a field in a table and set that field to the Attachments data type. You cannot share attachments between a Access (.accdb) database and a database in the earlier (.mdb) file format. You can attach files only to databases that you create in Access and that use the. Remember these guidelines as you work with attached files: For information about database design, see the article Database design basics. You cannot view or work with those tables.įor information about viewing other system tables, see the article Guide to the Navigation Pane. However, attachments do not break any design rules, because as you attach files to a record, Access creates one or more system tables and uses those tables behind the scenes to normalize your data. So at first glance, attachments seem to break the rules of database design because you can attach more than one file - one piece of data - to a field. For example, if an address field contained more than one address, finding addresses would be difficult, if not impossible. Attachments and database design rulesīy default, each field in a relational database contains only one piece of data.

#REPORT DATAB BAR ACCESS INSTALL#

In contrast, Access stores the attached files in their native formats with no supporting images, and you do not need to install additional software in order to view the images from within your database.

For example, if you store JPEG image files in an Access database, every computer that runs that database requires another program that is registered as an OLE server for JPEG images. In addition, OLE requires programs called OLE servers to function. By using attachments, you open documents and other non-image files in their parent programs, so from within Access, you can search and edit those files. When you viewed an image or a document from your database, OLE showed you the bitmap image, not the original file. Those bitmap files could become quite large - as much as 10 times larger than the original file. By default, OLE created a bitmap equivalent of the image or document.

Earlier versions of Access used a technology called Object Linking and Embedding (OLE) to store images and documents.

#REPORT DATAB BAR ACCESS PLUS#

You can now attach one or more resumes to the record for each contact, plus a photo of each contact.Īttachments also store data more efficiently. For example, let's say you own a job contacts database. You can use attachments to store several files in a single field, and you can even store multiple types of files in that field. Use attachments without a mouse or other pointing device Note: The functionality explained in this article doesn't apply to Access web apps.
