DTM_SETFORMAT message
Sets the display of a date and time picker (DTP) control based on a given format string. You can send this message explicitly or use the DateTime_SetFormat macro.
Parameters
-
wParam
- Must be zero.
-
lParam
-
A pointer to a zero-terminated format string that defines the desired display. Setting this parameter to NULL will reset the control to the default format string for the current style.
Return value
Returns nonzero if successful, or zero otherwise.
Remarks
It is acceptable to include extra characters within the format string to produce a more rich display. However, any nonformat characters must be enclosed within single quotes. For example, the format string "'Today is: 'hh':'m':'s ddddMMMdd', 'yyy" would produce output like "Today is: 04:22:31 Tuesday Mar 23, 1996".
Note
A DTP control tracks locale changes when it is using the default format string. If you set a custom format string, it will not be updated in response to locale changes.
