Hi, I have problems setting the Value of a DateTimePicker control of Windows Forms. The Value property *is* set (I can print it), but if displayed only the current date is shown in the control, not the value I have set the Value property set to before. The python version is 2.3, the .net versions tested are 1.1 and 2.0. Here are some code snippets: #----------------------------------------------------------------------- def dt2SysDt(dtFrom, incr = 0): #----------------------------------------------------------------------- "python date/dateTime in .net-DateTime(Date) umwandeln" return (System.DateTime(dtFrom.year, dtFrom.month, dtFrom.day) .AddDays(incr)) #----------------------------------------------------------------------- def sysDt2Dt(dtFrom, incr = 0): #----------------------------------------------------------------------- ".net-DateTime(Date) in python dateTime.date umwandeln" dtFrom = dtFrom.AddDays(incr) rv = datetime.date(dtFrom.Year, dtFrom.Month, dtFrom.Day) #print "sysDt2Dt=", rv return rv .... # set the value self.dtpErzeugtVon.Value = dt2SysDt(src.dtErzeugtAb) # display the values of dtp's for ctl in (self.dtpErzeugtVon, self.dtpErzeugtBis, self.dtpVersendetVon, self.dtpVersendetBis): print "dtp...=", ctl.Name, ctl.Value, sysDt2Dt(ctl.Value) # the print statement shows the following ... dtp...= dtpErzeugtBis 31.03.2007 00:00:00 2007-03-31 ... When the form is shown with ShowDialog(), only the current date is show (march 7 instead of march 31). Does anyone have an idea? Thanks Peter Schwalm
