2017-06-20Add FORM_GetSelectedText() function.Diana Gage
This function copies the selected text from a form text field or form combobox text field into the buffer parameter and returns the length of the selected text string. When buffer is a nullptr or buflen is less than the length of the selected text, this function does not modify the buffer and only returns the selected text length.
