Sets the Unicode character format flag for the control. This message enables you to change the character set used by the control at run time rather than having to re-create the control.
A value that determines the character set that is used by the control. If this value is TRUE, the control will use Unicode characters. If this value is FALSE, the control will use ANSI characters.
- Must be zero.
Returns the previous Unicode format flag for the control.
The Unicode format flag is used by Microsoft Windows NT systems with version 4.71 of Comctl32.dll or later. Therefore this message is supported by Windows 2000 and later, and by Windows NT 4 with Microsoft Internet Explorer 4.0 or later. It is only useful on Microsoft Windows 95 or Microsoft Windows 98 systems with version 5.80 or later of Comctl32.dll. This means that they must have Internet Explorer 5 or later installed. Windows 95 and Windows 98 systems with earlier versions of Internet Explorer ignore the Unicode format flag, and its value has no bearing on whether a control supports Unicode. For a discussion about how to test whether a control supports Unicode, see CCM_GETUNICODEFORMAT.
