Windows - Timer - Service To Execute On The Half Hour And Top Of The Hour Marks

May 6, 2009

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.

[CODE]...

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?

Convert A 24 Hour Time To 12 Hour In .net As Hh:mm AM/PM?

Jun 12, 2012

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

Synchronising Clock With System Clock?

Mar 12, 2009

I'm a totally newb to VB and I want to do this. I want to do display system clock into a textbox. The trick is that I want it to be synchronized with the Windows XP clock. I want to have something like +/- 100 ms accuracy.

Each 'second' change will trigger an output pin to ground into the parallel port. This is very important that the 'second' change in the same time the Windows XP second change. Do not care about the parallel output thing, I'm nearly there. My main concern is the synchronisation with Windows clock.

In my code, I've added a counter that increment +1 at each 'second' change. So, when the 'n' value will reach a determined value, it will trigger another event.

[Code]...

I searched on the net and I found a thing about NIST time server.. Maybe this could be an otpion, but I have even no idea about how using it... I'm a total newb, but I'm ready to learn. So, please use simple language, no hard to understand acronym etc.

VS 2008 VB Basic Window Attributes - Display A Digital Clock

May 14, 2011

I have created a simple app to display a digital clock, it can create child windows (dialog boxes) to do various chores, one of those chores involves a lengthy background task, so I create it in a modeless manner, so it doesn't block the main program. It all works well... kind of took me awhile to figure it all out, but there is one little cosmetic issue.

VS 2008 DateTimePicker?

Mar 14, 2011

Does anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem

VS 2008 Datetimepicker Value Needs 2 Digit Day

Nov 11, 2009

How can I get the datetimepicker value to have a 2 digit day EX. If it was November 6, 2009 the value is showing as 11/6/2009 but I need it to be 11/06/2009

I have a search that searches by date and Im using the datetimepicker. the date format in from my sql database is in MM/DD/YYYY not MM/D/YYYY So my results come up ok if the day is a 2 digit day normally (ex. 11/20/2009)but if its a single date (11/6/2009) I don't get any results because it is looking for 11/06/2009 I don't see how I can get the value of datetimepicker to be MM/DD/YYYY Even if i set the custom format to MM/dd/yyyy the value is showing up as MM/d/yyyy

VS 2008 Adding To DateTimePicker Control?

Nov 26, 2010

Wasn'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.

VS 2008 DateTimePicker Highlighting Disappeared

Jan 12, 2012

We have this custom DateTimePicker in our project where you can alter the BackColor and so on. But normally, when you click on the month of a DateTimePicker, it gets highlighted and you can change it with for example the arrow buttons on your keyboard or by typing a different number. Now the problem is that in our DateTimePicker, the highlighting doesn't happen anymore. When you click on for example month, you'll be able to change month but you don't see wether you selected month or something else.

This is the code we have (it's old code from way before I even started working here):

Public Class ucBaseDateTimePicker
Inherits System.Windows.Forms.DateTimePicker
' true, when no date shall be displayed (empty DateTimePicker)
