Change the attribute type in CListBox

[Huskey]

Hi,

I have a CListBox displaeyd with the column as shown:

CheckBox Time Float
CheckBox Toronto String
CheckBox NewYork String
CheckBox California String
CheckBox Status String

Besides, I have created a dialog box to change the attribute type (Choice: Float, string, int). For example, if I click on Status line, and then push a change the attribute type button, I can select which attribute I want to change. After closing the attribute dialog box, the changes will be effective immediately in the ListBox.

CheckBox Time Float
CheckBox Toronto String
CheckBox NewYork String
CheckBox California String
CheckBox Status Int

Also when I click on the status line, the default value shown will be String in the attribute dialog. How to do that? I have been trying many method but not successful. Please help. I deeply appreciate that. Many thanks.
