Looking for code

[gumi]

Hi,
I am looking for code for a alarm clock program that pops up a messege to be
used as part of my VB.Net class project. Any help is very much appreciated.

Thanks

Gumi:

I don't know of any project but I'm sure there is one. however, creating
this would be very easy depending on what you needed the clock to look
like...if it's a digital clock it'd be a piece of cake. Create a form or
usercontrol and drag a label onto it. Set the format specifier of the label
(or textbox) to Time or DateTime , basically whichever format you wanted.
You may want to create some properties that will allow the user to change
this .. Then I'd create an indexed property to hold the value of times you
wanted the thing to pop up at. You could also have a different property
that would cause it to alert every X minutes. You could use simple
division to implement this instead of the indexed properties b/c if you
wanted it to alert every five minutes, it'd be silly to store 24 hours worth
of 5 minute intervals in a property when division would do the trick a lot
easier. So depending on the user need you may want either or both..

Now, just spin off a background thread and check the times in the
property(ies) against the current system time DateTime.Now(); if there's a
match, show the form modally or run it as a control or notify icon, that
part depends on the use case but the logic is the same regardless. For set
intervals you could just use a Modulus or you could use a Greater than start
time and Less than end time and Not Already Shown type logic.

Hi Gumi,

This is the most simple alarm clock, drag a normal timer, a textbox and a
button to your form and than in the code.
\\\
Private Sub Button1_Click_1(ByVal _
sender As System.Object, ByVal e As _
System.EventArgs) Handles Button1.Click
Timer1.Interval = CInt(CDbl(TextBox1.Text) * 1000)
Timer1.Enabled = True
End Sub
///
\\\
Private Sub Timer1_Tick(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Timer1.Tick
Timer1.Enabled = False
MessageBox.Show("Time is expired")
End Sub
///
This is simple, for 1 second by second, you should take care the user can
only enter numbers.

To see a nice clock, you can look in the Resource kit at GDI
http://msdn.microsoft.com/vbasic/vbrkit/default.aspx

And if you have problems installing it
http://msdn.microsoft.com/vbasic/vbr...q/#installvdir

I hope this helps a little bit?

I don't know if this is what you're looking for, but it's an simple
example of an alarm, you just fill in the time and a message to be
displayed at that time and press activate. It's just something basic I
made 2 minutes ago, maybe it can help you.

copy and paste the following code:

End Sub

'Form overrides dispose to clean up the component list.

I've changed my previous code a bit, now if you press activate the
message and time get added to a listbox so you can add multiple
messages, you can delete a warning from the listbox by selecting it
and pressing delete.

I have programmed an excellent timer. I now want to program a 24 hour alarm clock using the computer clock as the reference. DateTime gives me 12:00 midnight. How do I compare it to TimeOfDay (add subtract, greater than, less than) so that I can make a message,splash, etc come up? I keep getting the message: "operand - is not allowed for date to date.
Maybe change the DateTime,TimeOfDay to strings and then compare?

I'm not sure what's exactly your problem, but you can have a look at the
DateTime and TimeSpan data types and their members.

I have programmed an excellent timer. I now want to program a 24 hour
alarm clock using the computer clock as the reference. DateTime gives
me 12:00 midnight. How do I compare it to TimeOfDay (add subtract,
greater than, less than) so that I can make a message,splash, etc
come up? I keep getting the message: "operand - is not allowed for
date to date." Maybe change the DateTime,TimeOfDay to strings and
then compare?

I'm not sure what's exactly your problem, but you can have a look at the
DateTime and TimeSpan data types and their members.

i am trying to return the number of days/ months and years from an
entered date to today. i want to be able to add and subtract various
dates. do you know an simpler way?

Please post the relevant code only. If you paste the code in notepad first
and copy it from there to into your posting, no blank lines are inserted and
identation is kept unchanged.

Your code can not be compiled. First enable Option Strict in the project
properties. It shows some obvious errors.

As I said, have a look at the datetime and timespan structures and their
methods. Example:

dim d as date
dim diff as timespan

d = New Date(yearBox.SelectedIndex + 1900, monthBox.SelectedIndex + 1,
daysBox.SelectedIndex + 1)
diff = d.subtract(date.now)

msgbox diff.totaldays
