Hyperlink fields

You can select an object on the Design or Preview tab and create a hyperlink to a web site, a local HTML file, a field value, an e-mail address, or another Crystal Report file.

The hyperlink is saved with your report and is available to other users as a way of viewing additional information.

Note:    Crystal Reports also lets you create hyperlinks with Relative URLs, so your web reports retain independence from their location on any particular server. To use a Relative URL, first set the Hyperlink type to "A file"; then delete the default prompt—file:///—from the File Name field, and replace it with your Relative URL.

To create a hyperlink field
  1. Select a report object on the Design or Preview tab.

    Note:    If you want to create a hyperlink to another Crystal Report file, do not select a report object.

  2. On the Insert menu, click Hyperlink.

    The Hyperlink tab of the Format Editor dialog box appears.

  3. Click the type of hyperlink you want to create. The available types are:
  4. After you have chosen a hyperlink type, enter the appropriate hyperlink information (the URL of a web site, for example).
  5. Click OK when you are finished.

The hyperlink is inserted as appropriate. Click it on the report to go to the appropriate site, e-mail address or other report.

Note:    If you set the hyperlink type to "Another Crystal Report file", you are creating an on-demand subreport (see Subreports). Just as one subreport cannot contain another subreport, you cannot create a hyperlink between two subreports.

BLOB (Binary Large Object) fields

A BLOB field is a database field whose data consists of Binary Large Objects—such as bitmap graphics, images, OLE objects, metafiles, and so on. Inserting a BLOB field into your report allows you to access these binary objects as you would other data types.

In general, Crystal Reports allows you to access BLOB fields containing:

In addition, if your data resides in a Microsoft Access database, then Crystal Reports enables you to report on BLOB fields containing OLE 1 and 2 objects and metafiles.

You insert BLOB fields as you would any other database field. For details, see To insert a database field.

A BLOB field object differs from other database field objects in that it offers options to control cropping, scaling, and sizing—just like an inserted picture or OLE object. To access these options, right-click the BLOB field object, select Format Graphic from the shortcut menu, and click the Picture tab.

Note:    To retain the ability to activate and edit an OLE object with its server application, you should insert the object into your report independently, either by linking or by embedding, rather than inserting it in a BLOB field. For more information about inserting linked and embedded OLE objects, see Inserting OLE objects into reports.
