How Can I Keep my program running smooth??

Hey
I've been writing this program for about a week now, and its just getting larger and larger in size. And I've noticed that the program is starting to run much slower. Forms will half disapear and then a few seconds later completely disapear. and the transition time between going from one form to the other is much longer.
Is there some kind of tips you guys use to keep programs running smooth, and take up less memory?

Thanks in advance for any suggestions / comments..

Well first off,
check the code to make sure you're not doing something stupid.

VB Code:

For i = 0 To 100
    Form1.Show
Next i

Then try the normal code optimization procedures.
Use faster data types, eg. the Long data type.
Try to reduce the code required for particular things.

Try not to have replicated code.
Write Subs/Functions to avoid this.

Erase un-needed arrays, avoid large dynamic arrays, unload un-needed objects etc.


Also try to keep frequently used pieces of data in memory as opposed to loading from the drive or elsewhere...

I'm pretty sure setting a string to "" when you're done using it and if you have a bit more code to execute before it goes out of scope will free some memory.

I was thinking, since modern 32 CPU are 32-bit, wouldn't VB's Integers have to be converted to 32-bits before the CPU can work with them?

While I agree with because you'll have better source code, wouldn't not doing this make a faster running app?

Is it better to load and unload a form each time You have to use it, and when your done using it?
Or should you load everything up at the start?

actually it will make the program take less memory (even after being fully compiled) So you sort of trade off a little bit of time for free memory space and remeber as soon as you program hits virtural memory it cuts to 1/10th the speed.

Well its best to use the Long, because *anything* else has to be converted first.

.. well ya know what I mean ...
