In my program's Form_Load I randomly generate a time value. Once I generate the time value, I put it in a DateTime variable. I need it to work like a clock. I know I can do this with a timer with an interval of 60000, or using TimeGetTime and updating a variable.Is it possible to do this with a thread?

Is there some way to generate a virtual disk/path?My application needs to generate a lot of temporary small files, edit them, write to disk, execude old executables in Fortran, and read the text files outputs.I cannot choose to avoid the fortran, because is out of my power to decide it.all that I/O is really expensive, because disk access is slow. But all the files involved are really small (including the executable), so they may fit on a few megabytes of RAM, and I have gigabytes of RAM available (RAM is really cheap today).Worse, I cannot parallelize, because it forces me to multiply I/O operations (I need to create, edit, and delete lots of small files).The perfect solution would be to have a small virtual disk in memory.I cannot use a virtual PC software, because users would have a hard time installing it (they have problem using windows explorer even to do simple tasks).
View 4 RepliesI have to make a card game called SNAP. The point of the game is that two players will flip their card and if they match then one of them have to call out snap. The first one to call out snap gets the card.
I'm having trouble on getting the cards to generate randomly but match every now and then.
how to do this certain section of it. I want it to take a group of first names and randomly pair one with a last name randomly selected from a separate group. something like this:
Group 1-BobJoeBrianJillJorge
Group 2-SandersRientzLopezGumpStaudmann then output something like "Brian Staudmann" or "Jorge Gump"
Except I want a significantly larger selection of first and last names in each group. Would it be best to save them in an array? A String? Parse from textfiles?
So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..
I am making an application that randomly generates numbers. I then have to find out if those numbers are even or odd. Then place them in the corresponding array ( EvenNumbers() or OddNumbers() ). Then display the random numbers array then the even and odd numbers array. I am up to the point where I have the generated numbers and can tell if they are even or odd, but can't get them into an array. I am trying to do it like this....
[Code]...
What's the fastest way to randomly generate numbers, either randomly or simulating random? I don't really need a true random number generator, it would be acceptable to simulate random. I tried other random simulation methods but none were faster than this. Here's the fastest way I have now:

I'd like to get the clock running on my program which is the clock from the computer and displays it into the label text of my window form. I'm using VB 2008 Express edition and I only get the current value of the time at the moment the application starts but not running as a clock.Is there anyway to do this? I used the line 'Me.Label3.Text = TimeOfDay'.
View 4 RepliesI have developed a 32-bit VB.NET application that runs fine on 32-bit systems. Some of the folks in engineering, however, are using 64-bit machines, so we have created 32-bit virtual PCs and installed the application on the Virtual PC. When we try to run it, however, the application fails to establish a connection to the SQL server (remote, SQL 2000) for login validation.
View 11 RepliesI was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?
I'd like to write a small app to get the time from an "atomic" clock -- I believe the UTC time and then compare this against the system clock.
So far I've been able to get the system time details with the code below but just cannot figure out where to start on getting the atomic clock(s) time.
I did Google this for examples and have not found anything useful, I did find a list of atomic time servers @ the following URL and realise I have to connect to NIST Internet Time Service clock
Dim localDirect As Date = Date.Now
Dim utcDirect As Date = Date.UtcNow
Dim localFromUtc As Date = utcDirect.ToLocalTime()

I would like to make an alarm clock application, however I am having some problems in the brainstorming phase.
My main problem is the fact that I dont know how to ensure the application will be able to calculate the time and thus set off the alarm. For example, when the application is closed, how will the alarm go off?
Ideally I would like to make this app a system startup item, so if the system is rebooted, the application will automatically relaunch - but again, I dont know how to do that.
If the system is sleeping, how can I wake it up? These kind of problems.
Another dilema I have, is if this application is always running, how could I have it go to my taskbar hidden icon menu (the right section of the taskbar next to the time).

The clock needs to be synchronized with a server but I really don't want to have it constantly check the server as the page will be open 24/7 on several PCs. Is there some way to get the time from the server and then use the systems clock to keep it updated and check the server every 15 minutes or so to keep it synced?

View 3 RepliesI have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control. But instead of that approach, I'm thinking about displaying a 'clock' image and shading those areas with some color. This is similar to a Pie Chart. But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.
View 25 RepliesI'm in need of a "global" type timer that will allow me to basically run a clock the entire time someone is on my site, no matter what pages they go to. I've played around with the timer available for forms but I didn't see a way to make it continue to run after someone left that page.The effect I'm attempting to create is for a timer to start whenever someone hits my site, then every X minutes an event will trigger. This event should happen no matter where they are on the site. I've read a couple articles on timers but to be honest I'm fairly new to VB and I didn't know if I really needed to learn about 'threading' etc, to get a timer to work.

View 12 RepliesHow long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -
loop
stopwatch stop

I am trying to change the background randomly from a selected list after a certain amount of time. I have the array set-up and I have it picking a random path (ex c:images est.jpg). I found in the registry the background image settings. I tried setting the registry key to the path but it seems like there is more to it than that because it doesn't change it. I also saw where it stored the file and tried changing it but again it doesn't change it. The funny thing is if I go to display properties afterwards it shows the correct image just doesnt set it. If I then click a different image and go back to it then it sets it. How can I make it update the background?
