Multiple listboxes with different actions.

[sonic]

Hello!

How can i create a dialog with multiple listboxes and use these as input?

For example:

Listbox 1: a/b/c
Listbox 2: 1/2/3 or 5/6/7
Listbox 3: one/two/three

If in listbox 1 a is selected, the 1/2/3 option in listbox 2 should apear, if b is selected, 5,6,7 should apear
When in listbox 3 two is selected is should message 'a happy welcome' when three is selected the message should be 'poor you'

Can somebody give me an example for this?

Gintaras, thank you for this!

Is the last thing i asked also possible, when in another listbox, the third one, is selected something, the action depends on what is selected?

So listbox 1: a so a selection in listbox 2 is 3 and when finaly in listbox 3 'two' is selected a message apears?

Thanks in advance for your time!

Can't this be done?

Code for listbox 3 would be similar as for listbox 1, just simpler. Or i don't understand question.

Hello Gintaras,

What I mean is that the action depends on the selection in the different listboxes.

When in the second listbox a selection was made, the selection in the third listbox gives another action than another selection in the second listbox.

By example

Listbox 1 the selection is 'a'
The second lisbox gives a possible selection of 1/2/3
Listbox 1 the selection is 'b'
The second lisbox gives possible selection of 4/5/6

When in second listbox 2 is selected, the third listbox gives possible selection of one/two
when 'one' is selected a message appears.

But when in second listbox the selection was 5 (which depends on selection in first listbox) another message appears.

I hope you can help me with this, and that this is a better explenation for what i need.

Greetings

Sonic

The example shows how to use functions and events for tasks like this.
Add another event LBN_SELCHANGE to execute code when listbox 3 selected. You can add it in Dialog Editor.
Use function LB_SelectedItem to get index of selected item in any listbox. Use id(your_listbox_id hDlg) instead of lParam.
Then use sel _i to execute different code depending on what is selected.

Thanks for your answer!

But when i try this, the action doesn't differ from the first selection. It doesn't seem to matter what selection in the first or second listbox was made... the case-index 0/1/2 cannot 'see' what the previous selection was...

I'm sorry when i look stupid, but when you can help me with this (and you do) it would be great!
