I don't know of any calendar programs that will allow you to insert a hyperlink, (I can see what you would like and its a very good idea, creating a link inside the calendar page that you can click on to open up a page with more information about a particular entry).
And I don't use Outlook or Outlook Express. Sorry I'm not doing very well so far am I.
But, you ""can" insert hyperlinks into Word documents, and also into Excel Spreadsheets.
If I were to create a calendar I would consider using an Excel Spreadsheet to do it, and have 1 worksheet per month, or 1 per week, etc, and insert my diary events into individual cells.
In a cell you could place a hyperlink to another cell, or worksheet, or workbook, or even hyperlink to another document outside of the spreadsheet, and so disply further details.
The cell would show something like "Dentist today" and then go to Insert > Hyperlink, and in the Hyperlink dialogue window type "Text to display" as "Dentist today", click on the right Link to button on the left, (eg Link to: Exisiting file or web page), then navigate to the folder on your hard disk where you have stored the further details note. Or you could link to a different place in the same workbook, perhaps a worksheet called, "details", or whatever.
This perhaps wouldn't be a very elegant calendar, and you couldn't display it without opening up the .xls file from Excel each time, but you could customise it with background pictures and color formats as you wished.
In the Computer Newbies forum Degs was seeking advice about creating an excel calendar, and posted his version on the internet for people to see. I'm sure he wouildn't mind you looking at it. It is simple, yet functional for his needs.
You could see his thread at ;
And his calendar at ;
One further thing. Mozilla have produced a stand-alone calendar from their Firebird browser project called Sunbird. It isn't clear if you can place hyperlinks in the calendar, although I saw a suggestion you could in their newsgroups. Sunbird is detailed at;
I hope any of this helps.
