EM_GETLANGOPTIONS
wParam = 0 ; // not used; must be zero
lParam = 0 ; // not used; must be zero
The parameters are not used; they must be zero.
The return value is a combination of the following bit flags, which indicate the current language option settings.
| Enumerator Value | Meaning |
|---|---|
| IMF_AUTOKEYBOARD | If this flag is set, the control automatically changes the keyboard layout when the user explictly changes to a different font, or when the user explictly changes the insertion point to a new location in the text. |
| IMF_AUTOFONT | If this flag is set, the control automatically changes fonts when the user explicitly changes to a different keyboard layout. |
| IMF_IMECANCELCOMPLETE | This flag determines how the control uses the composition string of an IME if the user cancels it. If this flag is set, the control discards the composition string. If this flag is not set, the control uses the composition string as the result string. |
Windows NT: Requires version 4.0 or later.
Windows: Requires Windows 95 or later.
