【 在 skyice (skyline) 的大作中提到: 】
: 在程序运行期间如何使一个编辑框只读，不是disable？
向编辑框发送EM_SETREADONLY消息，其在WIN32API中定义如下：
An application sends an EM_SETREADONLY message to set or remove the re
ad-only style (ES_READONLY) of an edit control.
EM_SETREADONLY
wParam = (WPARAM) (BOOL) fReadOnly; // read-only flag
lParam = 0; // not used; must be zero
Parameters
fReadOnly
Value of wParam. Specifies whether to set or remove the ES_READONLY st
yle. A value of TRUE sets the ES_READONLY style; a value of FALSE remo
ves the ES_READONLY style.
Return Values
If the operation succeeds, the return value is nonzero; otherwise, it
is zero.
Remarks
When an edit control has the ES_READONLY style, the user cannot change
the text within the edit control.
To determine whether an edit control has the ES_READONLY style, use th
e GetWindowLong function with the GWL_STYLE flag.
