c# - How to set default month and day in the datetimepicker? -


i have searched online , managed find codes set year month , day.

datetimepicker2.value = new datetime(2017,12,31);

i tried using custom format , not seem work

datetimepicker2.customformat = "dd/mm"; datetimepicker2.value = new datetime(12,31);

you cannot create datetime object day , month. datetime doesn't have kind of constructor. datetime constructors

so need go kind of "workaround"
- use "dummy" year , when need use date - use month , day properties.

var dummyyear = 2000; datetimepicker2.value = new datetime(dummyyear, 12, 31);

another workaround use parseexact method create datetime based on format using "dd/mm"

var date = datetime.parseexact("31/12", "dd/mm", cultureinfo.invariantculture);  datetimepicker2.value = date; // 12/31/2017

notice when did not provide year - current year used.
notice: dd invalid format days should lower case "dd"

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
