=====ShowVisioAction=====

This is the development page for the ""ShowVisio"" action

Please feel free to make changes or leave comments!

There are 2 ways to show a Visio document within a Wikka page and they both require the MS Visio Viewer plugin. 
You can get it from http://www.microsoft.com/downloads/details.aspx?FamilyID=3fb3bd5c-fed1-46cf-bd53-da23635ab2df&displaylang=en

I have tested it with IE and it works very well. Sadly, it does not work with Firefox.

~1) Using an action
~""{{visio url="http://devpc/application%20data/rpc_http_diagram.vsd" height="750" width="900"}}""
!This was based on the Mindmap.php action. Thanks go to the author of that action!

~2) Using iframe
~ ""{{iframe width="1200" height="2000" url="http://devpc/application%20data/rpc_http_diagram.vsd"}}""

I came up with the action before I realised that it could also be done with an iframe. If anyone can point out the pros/cons of each approach, I'd be grateful.

Sample usage:

	Height and Width are optional.
