SUMMARY
Under the Microsoft Windows graphical environment, multiline and single-line edit controls do not accept characters with virtual key code values less than 0x20. The two exceptions are the TAB and ENTER keys; users can enter these characters only in a multiline edit control.

MORE INFORMATION
If an application creates an edit control with the ES_LOWERCASE or ES_UPPERCASE style, text entry is converted into the specified case.

If an application creates an edit control with the ES_OEMCONVERT style, the text is converted from the ANSI character set to the OEM character set and then back to ANSI for display in the control.
