With the advent of Faster Chips etc - should applications developers be concentrating on Program structure Vs Optimising for Speed ?
When first developing a solution to a problem - I develop an algorithm that solves the problem - If this problem is a new problem - I find it extremely difficult at the semantic level to think of more efficient solutions - gets easy once the program is coded - I always just code the first working solution I get - is this the same for you - please contact mw with your thoughts - as I do not use any optimisation techniques - only do if programs are slow I use Vb 5.0 - what do you think then ??

When you will experience with VB, you will see that all the code you will write will be nearly optimized (of course, you have to take care to have a readble application for later maintenance).

There is a lot of little optimization you can done easily without thinking too much.

Ex : If you go through all a recordset, (1000 records), don' t use the following code :

   Do while record.EOF = FALSE  

Use instead

   For nI = 1 to record.Recordcount

This is due that in the first sample, you will test each time the EOF of the recordset. In the second sample, you will never do that. This increase a lot for large recordset.

If you are interressed, I have written a document indicating how to write a VB app with optimizations...
