Performance upgrade

[andrefpc]

Hello experts! In my QV project I use a lot of expressions, for performance upgrade I was thinking of store every expression in a .txt which will be included in the script, my question is: the expressions will be calculated only once and presented where needed or, for every object the expression is recalculated?

Thanks!

For every selection all expressions are recalculated, but in a very optimized way (using cache)

I don´t think you´ll perceive difference using the expressions based on a txt file.

You should work into optimizing every expression (using flags, etc)

Hi Andre

I rather recommend you to create Variable instead of storing expressions in a .txt file that's a wrong approach.

Create variable once and enter your expression value there. This is one time activity.

After creating variable for a particular expression call that expression eg. vLastQuarterSales in your Bar Chart, Straight Table, Text Box, anywhere. It will just work fine and easier for you.

It's the Best Practice. Also your Application Performance will surely be increased.

Thanks for your reply Nag, my question is...every time I call that variable in different objects is it recalculated?
