    Get a Window HWND by only knowing the ID.

    I created a few comboboxes in runtime...

    I know the ID of the each control, but I don't know how to get its HWND... I try GetDlgItem but didn't work...anyideas?

    Right know, my main idea is use std::map or std::vector, but I trying to not use the c++ runtime...

    For a valid child window identifier and a valid parent window handle, GetDlgItem will return the window handle for the child window with the given id. If that function is failing to return a valid handle then either the parent handle you are using with it is invalid or there's a problem with the id.

    But GetDlgItem is for dialog controls...my comboboxes are created by CreateWindowEx...does it matter?

    Not in the slightest.

    See GetDlgItem.
