Sorting a list that contains a type

[Ricky D]

I'd like to implement some file functions that would allow me to save my types to files.

Type tyepAddmenuItem(Id As Int, MenuItem As String

I understand a List can hold multiple entries of these but I'd like to know how I can sort on either the Id or the MenuItem.

I know this is possible in sqlite but I'd like to get it working with my custom types.

regards, Ricky

Assuming you named your list flist and added a number of your typed records to it:

flist.sorttype("Id", True)

will sort by the field Id in your type, in ascending order. "MenuItem" will do the same with that field in your type.

Thanks, I'll give it a go when I get home

cheers Ricky

That doesn't work.

SortType isn't coming up on the List even though the docs say it's there.

I don't know what's wrong.

What version of b4a do you have?

 

[Ricky D]

1.8

 

[Erel]

List.SortType was added in B4A v1.9.

 

[Ricky D]

i downloaded the 1.9 trial version.

it works there.

I renamed the core.xml & core.jar files in 1.8

copied them from 1.9

It now works.

Note that it is not recommended to use a Core library (and B4AShared.jar) of a different version. You may encounter unexpected issues.

Please clarify, ----MORE DETAIL PLEASE-----

are you referring to the Android version that the shared library from java was referencing when it was created as compared to the Android version B4A is referencing ???


What Android version is B4A referencing.

No. He wanted to use the core libraries from Basic4android v1.9 with Basic4android v1.8. This is not recommended as somethings will not work properly.
