The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

Windows version 3.1 introduces the ES_READONLY edit control style. When an application creates a control and specifies the ES_READONLY style, the control retains all the text display properties of an edit control while preserving the content of the control from any modifications.

RROEDIT is a file in the Microsoft Software Library that demonstrates how to create a read-only edit control using techniques that are compatible with Windows versions 3.0 and 3.1. Using the techniques demonstrated by RROEDIT, an application can switch an edit control to read-only mode and back to normal behavior.

Download RROEDIT.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download RROEDIT.EXE (size: 23894 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get RROEDIT.EXE (size: 23894 bytes)

The RROEDIT sample subclasses the edit control. In read-only mode, the subclass procedure traps the WM_CHAR, WM_CUT, and WM_PASTE messages and throws them away. All other messages are processed without any intervention from the subclass procedure. The user can copy text from the edit control at all times.
