how to show up datetimepicker value in which hour & minute only to display. e.g. (10:00 AM) There's no seconds to display.
View 14 RepliesBasically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.

I wrote a VB.NET Windows Service, which works fine. I have only one issue with it. I want the service to execute on the half hour and top of the hour marks (e.g. 9:00, 9:30, 10:00, 10:30, 11:00, etc etc etc). I am using the following code:
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.

This code works, however, if the service starts at, say, 10:15, then it executes at 10:15, 10:45, 11:15, 11:45. How do I make it so it always executes on the 30 minute and top of the hour marks?
i have a problem on setting the default value of my date time picker. i have created this application
[code]...
and my problem is i want to set the default value of my DateTimePicker(dtpDate) depending on which date was clicked on the calendar in Main Form. i've been posting this program of mine this past few days now. i just really need to finish this for my upcoming thesis defense.
I am querying a date from my Access 2007 database in the format: MM/DD/YYYY It's then saved as a string
Depending on the month and day, it might be 1 or 2 characters. To set the DateTimePicker, it takes it as this format: DateTimePicker.Value = New DateTime(YYYY, MM, DD)
How can I switch around the characters in my string so that it can satisfy the format the DateTimePicker wants? I was thinking about some kind of reader that "consumes" characters until it reaches a delimiter ("/") and then does something with it. I remember doing that in JAVA but not in VB.NET

I have a list box on my form with 2 value - "2010" & "2011". When I change the value in the listbox it should set the minimum and maximum value of 2 datetimepickers. Each time I try to change the value I get an error - for example if I change the listbox from 2011 to 2010 I get the error:
"Value of '31/03/2011 00:00:00' is not valid for 'MaxDate'. 'MaxDate' must be greater than or equal to MinDate. Parameter name: MaxDate"
If ListBox1.SelectedIndex = "0" Then
DateTimePicker1.MaxDate = #3/31/2011#
DateTimePicker1.MinDate = #4/1/2010#
DateTimePicker2.MaxDate = #3/31/2011#
DateTimePicker2.MinDate = #4/1/2010#
End If
If ListBox1.SelectedIndex = "1" Then
DateTimePicker1.MaxDate = #3/31/2012#
DateTimePicker1.MinDate = #4/1/2011#
DateTimePicker2.MaxDate = #3/31/2012#
DateTimePicker2.MinDate = #4/1/2011#
End If
So let's say I have 1400, I want to convert it into 2:00PM I tried the following:Dim convertedTime As String = DateTime.ParseExact(theTime,"HHmm", Nothing)
And it would give me this: 6/12/2012 02:00:00 PM
I do not want the date part, neither do I need the seconds. All I need is 2:00PM
I use a masked textbox, and I would control the input, the problem is, I use 1 textbox and the control should on the first 2 digits with a maximum of 24 and the last 2 digits with a maximum of 60. Is there a possibility to program this?

That is my issue. It's giving me 24 hour time, and I want 12 hour time, with out showing AM or PM.
changing the rest of the date?I mean... I have this...:vb 'current date at my gameDim time As Date = #9/29/0001 12:23:00 PM# 'another date variableDim period_lunch as date = #1:00:00 PM# 'and later at a Sub, I try to do this...time.Hour = period_lunch.Hour 'and I get an error saying time.Hour is read only I only want to set the hour to 1:00 PM of the SAME day of the time variable, not the one contained in period_lunch, that is. And the only built in procedures I see in the date object are for adding or subtracting WHOLE hours, minutes, etc. I will need to compare both dates, subtracting the difference and adding it to the former?
View 2 RepliesEvery time I make even a very small change to a form in the form designer, when I try to move off the screen to write code, or run the application, VS 2010 takes up to 1 hour to figure out what the small change was, process it and then let me continue. Is there some fix that I am missing to make VS 2010 be able to handle small changes to the form_designer, or is this just the way it is?
View 6 RepliesI have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.

View 1 RepliesIf you enter 11 for instance into the year component of the date then tab off the control the text returned to the validation function is the text before the year was entered rather than the new text.The problem can be overcome by making the control invisible then visible. This has been the case since Visual Studio 2003, it would seem to be a bug.
View 1 RepliesWasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
I am having the following problem, when the user wants to use the DateTimePicker (DTP), the date box shows in the middle of the screen. Then if the user wants to select a date he cant, instead the date box goes away and the DTP value remains unchanged. This is not always happening, sometimes it works fine and sometimes this happens.Please go to the link below for an image (you can see that the DTP control is on the left while the date box is to the right):[URL].. application is being run from a server to a local client on the user machine, I dont know if this has anything to do with it.
View 6 RepliesI know that you can create custom formats for the DateTimePicker control, and I've googled this but is there any way that you can allow a user to only select Sunday dates in a Month with this control?
