The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) versions 3.0 and 3.1
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

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.

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.
