Declaring an Edit control with certain styles, and altering the text, may have undesirable effects. Depending upon whether or not pointers to the text are passed to other functions, changing the text in place may generate an unrecoverable application error (UAE).

Declaring an Edit control with any of the following styles, ES_LOWERCASE, ES_UPPERCASE, or ES_OEMCONVERT, and calling either SetWindowText (hEdt, lpstr) or SetDlgItemText (hDlg, editID, lpstr) will alter the string in place. Calling either one of the above mentioned functions to alter a string contained in a code segment, which is labeled PURE in the corresponding .DEF file, will result in a UAE.
