Use of CallByName

[TorrediPisa]

Good Morning(Evening) to everyone

I am trying to understand the actual usage of the Function
CallByName.
Reading the guide, it is a function used to manipulate objects by either executing a method or setting the value of a property
Usage: CallByName(object, procedure, calltype, args)

For example,I have a Text1 in a form: if I write:
CallByName Text1, "ForeColor", VbLet, vbRed
I will obtain the same as:
text1.ForeColor = vbRed

Probably I have indicate a not much meaningful example.
Could you please explain me an example where the importance
of this function apperas more relevant.?

Thank You for Yr kind help.
Best Regards
TdP

One purpose is when the proceedure Name is stored in a DB Field or variable, you can either use a "Select Case" or "If" Statement to find out which method needs to be called, or use the CallByName method.
It helps when there are many different possible proceedures which could be called and the proceedure names are stored as a string.
But it does create extra overhead, which may or may not be of importance for whatever and however it is being used for.

Use a KeyWord search in this VB6 forum to see how others have found it to be useful.
