Visio + Delphi

Installation

Requirements:  Visio 4.5 or 5.x.  If you want to play with the code, then you will need Delphi 4  (Principles are similar for D3, but the code uses some open arrays, which D3 doesn't know about).

There's nothing much to installation. Simply copy the zip file to an empty directory and unzip.

Operation

The above image shows most of what there is to know about operating the demo.   Note that some of the buttons can result in Exceptions (for example attempting to Register for events if this app is not connected to Visio).  This intentionally reflects the results of these improperly attempted operations..

Compiling the Demo

Everything you need to compile the demo should be included, except for the Visio_TLB.pas file. You can easily generate this from within the Delphi IDE.  On a machine that has Visio and Delphi 3.x or 4.x installed, follow these steps.

• In Delphi: Menu Project -- Import Type Library: Brings up a list of Type Libraries.  
  • Several items mention Visio -- select the one that says something like "Visio 5.0 Type Library (Version x.x)".
  • There will be nothing in the Class names box, that's OK.
  • Unit dir name -- specify somewhere to put the generated files (it defaults to the Imports directory).
  • Hit OK.
• To enable Delphi to find the Visio_TLB file, either move it in the same directory as your project, or change the Project -- Options -- Directories settings appropriately.
