epiCode Active Member Licensed User Nov 24, 2021 #1 In the following two scenarios: B4X: .... processData (bv as view,..........) .... private sub processData(bv as view,....) ..... bv.add(somepanel,......) end sub AND B4X: .... somepanel = processData (some params..........) bv.add ( somepanel, .......) .... private sub processData(some params....) as somepanel ..... return somepanel end sub my queries are 1. which of these codes will be faster (assuming that processdata is called a lot of times during CLV loading) 2. will having many parameters passed through call reduce performance or it will be barely noticeable ? Thanks

No it doesn't. You can pass million views and it will be extremely fast. 1. Make sure to test performance in release mode. 2. If something is slow, it is unrelated to the views passed. When you pass a view, you are not making a copy of any object. It is a simple pointer that is passed.

While I appreciate what you want to convey here, this is stemming from the fact that when I'm passing whole lot parameters to reduce duplication of code it is actually slowing down CLV loading a lot - If I don't I am getting into unwanted initialization issues.

Thanks Erel - That clarifies that the slowdown issue has to be something in my code itself and not where the view related transactions happen. Upvote 0
