EM_FINDWORDBREAK
The EM_FINDWORDBREAK message finds the next word break before or after the
specified character position, or retrieves information about the character at that
position.
EM_FINDWORDBREAK
wParam = (WPARAM) (UINT) code;
lParam = (LPARAM) (DWORD) ichStart;
Parameters
code
Action to take. This parameter can be one of these values:
Value
| Meaning
| WB_CLASSIFY
| Returns the character class and word break flags of the character at the
specified position.
| WB_ISDELIMITER
| Returns TRUE if the character at the specified position is a delimiter, or
FALSE otherwise.
| WB_LEFT
| Finds the nearest character before the specified position that begins a word.
| WB_LEFTBREAK
| Finds the next word end before the specified position. Same as WB_PREVBREAK.
| WB_MOVEWORDLEFT
| Finds the next character that begins a word before the specified position.
This value is used during CTRL+LEFT key processing. Same as WB_MOVEWORDPREV.
| WB_MOVEWORDRIGHT
| Finds the next character that begins a word after the specified position. This
value is used during CTRL+RIGHT key processing. Same as WB_MOVEWORDNEXT.
| WB_RIGHT
| Finds the next character that begins a word after the specified position.
| WB_RIGHTBREAK
| Finds the next end-of-word delimiter after the specified position. Same as
WB_NEXTBREAK.
|
ichStart
Zero-based character position to start from.
Return Values
Returns the character index of the word break, unless the code parameter is the WB_CLASSIFY or WB_ISDELIMITER value. For more information,
see the description of the code parameter.
Remarks
If code is WB_LEFT and WB_RIGHT, the word break procedure finds word breaks only
after delimiters. This matches the functionality of an edit control. If code is WB_MOVEWORDLEFT or WB_MOVEWORDRIGHT, the word break procedure also
compares character classes and word break flags.
For information about character classes and word break flags, see Word and Line Breaks.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
