[英]get selected date from DATETIMEPICK_CLASS win32 (NOT mfc)
I have 1 datetimepick_class control placed on win32 form .我在win32 表单上放置了 1 个datetimepick_class控件。 I create it like below:
我创建它如下:
HWND Date = CreateWindowEx(
0,
DATETIMEPICK_CLASS,
TEXT("DateTime"),
WS_BORDER | WS_CHILD | WS_VISIBLE ,
10, 10
250, 30,
hWnd,
(HMENU)IDC_DATE_TIME_PICK,
hInst,
NULL
);
And I have button .我有按钮。 I want when this button clicked , it should get selected date value from that mentioned datetimepick widget.
我希望当单击此按钮时,它应该从提到的datetimepick小部件中获取选定的日期值。
I handle button clicked event as below:我处理按钮单击事件如下:
switch (message)
{
case WM_COMMAND:
{
int wmId = LOWORD(wParam);
switch (wmId)
{
case IDC_Calculate_Button:
//Button clicked so
//Display selected date value in msgbox
}
}
I tried existing answers but they are rare or not well documented or in detailed.我尝试了现有的答案,但它们很少见或没有很好的记录或详细说明。 Please guide me.
请指导我。
You can use DTM_GETSYSTEMTIME
message:您可以使用
DTM_GETSYSTEMTIME
消息:
case WM_COMMAND:
{
int wmId = LOWORD(wParam);
switch (wmId)
{
case IDC_Calculate_Button:
{
//Button clicked so
//Display selected date value in msgbox
SYSTEMTIME st{};
DateTime_GetSystemtime(Date, &st);
TCHAR buf[100]{};
wsprintf(buf, L"%d-%d-%d", st.wYear, st.wMonth, st.wDay);
MessageBox(hwnd, buf, L"Time", 0);
}
}
}
It works for me:这个对我有用:
