| Header file: | Winuser.h |
| Windows CE Versions: | 1.0 and later |
Syntax
EM_SETLIMITTEXT wParam = (WPARAM) cbMax; lParam = 0;
Parameters
cchMax
Specifies the new text limit, in characters. If this parameter is 0, the system sets the maximum text limit. For more information, see Remarks.
Return Values
None.
Remarks
The Win32 Platform SDK erroneously states that EM_SETLIMITTEXT sets the limit to the number of bytes specified by cbMax. Both Windows NT and Windows CE set the limit to the number of chars specified by the cbMax.
Windows NT
For single-line edit controls, the text limit is either 0x7FFFFFFE bytes or the value of the wParam parameter, whichever is smaller. For multiline edit controls, this value is either 0xFFFFFFFF bytes or the value of the wParam parameter, whichever is smaller.
Windows 95 and Windows 98
For single-line edit controls, the text limit is either 0x7FFE bytes or the value of the wParam parameter, whichever is smaller. For multiline edit controls, this value is either 0xFFFF bytes or the value of the wParam parameter, whichever is smaller.
