Updating & Embedding in a web page
Posted on 1998-06-25
Let me explain the tricky new project which I have been given. My speciality is Excel VBA, so I require some helpful advice on fields which are new to me.
I work for the HQ of our operation. Currently, financial data is sent to us each month from all over the world by reporting units. This data is stored in our Essbase database here, along with a record of when the data was sent to us (called a "timestamp").
We use an Excel based front-end running a special add-in macro to retrieve timestamps from the database, so that we can see which reporting units have sent data and which ones have not sent anything yet. This a good indicator of how close we are to having all the data we need, so we run this procedure often.
The goal is to make this list available to the whole company via the intranet (Lotus Notes / Domino system).
The ideal situation would be an HTML page displaying our Excel front-end worksheet, which would automatically update itself every five minutes to show the latest arrivals.
How the hell to do this ???!!!
Could you embed an Excel workbook in an HTML page, and use Visual Basic to trigger the "Update Data" macro every five minutes ?
Alternatively, could I embed the Excel sheet and macros in a Visual Basic program, along with some scheduling code, and then put a window to that program on the web page ?
Do I need to use two entirely separate processes (data retrieval -> HTML display) ?
Where do I need to focus my efforts - Excel or Visual Basic ?
How exactly would you go about designing this ?
Apologies for the massive scope of this question :)
Please, any design advice is gratefully received, with the points going to the best analysis of what exactly is required.
