Question

This is easy in .NET (not my question) but I’m trying to figure out if it is possible to simply change the text of a string in a Win32 list box control given an index.

There is a GetText function that takes an item index but nothing to change the text of an existing item/string. My workaround will be to remove it and add it back in the box (which is also a weird prospect since there is no single command to add a string + item data — these must be done carefully by inserting the string and then setting the item data on the index of the inserted string, which is tricky (not possible?) with sorting active).

Answer 1

Yes, the lack of a LB_SETITEMTEXT message is a bit weird.

You should put your Delete+Insert+SetData calls between calls to WM_SETREDRAW…
