_GUICtrlListView_GetItemText - proposal

[mlipok]

Add description something like this:
"If item or subitem not exist then function will return an empty string"

[mlipok]

I'm sorry too stingy description.
In one of the scripts I had a situation in which I used the index non-existent, which caused some complications.
I noticed that this function does not return any errors in the @error and @extended so I thought that the documentation could use at least a relevant mention of.

Please give favorable consideration to my proposal.

As an item/subitem could quite easily contain an empty string, I do not think that this is a reasonable proposal - how would you distinguish between a valid empty return and one returned by a non-existent item/subitem?

Also looking at the function in detail I cannot see an easy way to determine whether a returned item/subitem value is from a valid element. So in this case I believe it must be incumbent on the coder to do the necessary parameter checking before calling the function - the UDF should not need to do this for itself.

Thanks for your comments.
You have right UDF should not need do this.

but...
It would be good to do a note in HelpFile about it.

Because how you say:
"So in this case I believe it must be incumbent on the coder to do the necessary parameter checking before calling the function"

But he (coder) want to know about this incumbent.

The same remark could be made for any number of UDF functions. Either we add error-checking code to each and every UDF function - or we rely on the coder to check parameters before calling those which do not have a specific error return. I would class parameter limit checking as standard coding practice and not something that should be remarked upon for every function.

Thanks for the clarification.
If no one else has any other comments you can close this ticket.
