Write A Small Program That Shows A Clock Using A Timer In .net?
Feb 24, 2011
I am trying to write a small program that shows a clock using a timer in vb.net, I want the clock to display the time and date as a binary display i.e. if it's 10:01:21 the clock would display boxes or buttons in rows going from 1 to 2 to 4 etc upwards and changing colour when at certain times. the example time above would be a button for 8,a for 2 to make the 10 o'clock, a button for the 1 minute and a button for the 16, 4 and 1 seconds making 21 seconds.

I have to create a decorative digital clock, using VB2008
So far i have inserted a Picture Box control with a picture for the background of the form. I was told to use values Hour, Minute, and Second as Hour(Now), Minute(Now), and Second(Now ) to display a Digital Clock.

I are trying to write a small program for iTunes using Windows COM. We are able to talk to iTunes and create popup boxes that show the current track, and a few other small things. However, when we try to set this info to a Label for example, we get:
InvalidOperationException was unhandled by user code Cross-thread operation not valid: Control 'Label1' accessed from a thread other than the thread it was created on.
The program then hangs and locks iTunes from closing. I believe the issue is the event handler I have created, which I know very little about. We are using VB 2010, so that may change some things. We followed a rough example from a forum post HERE. If you scroll down the orange text, you will see a reply right after by Will Hughes with a "Handles iTunes.OnPlayEvent". If I add this to the end of my event handler, I get:
Handles clause requires a WithEvents variable defined in the containing type or one of its base types. Not sure if its important to the issue or not, but I found it curious. Our code is shown below.

What I'm trying to do is write a small program that copies a file from a USB to another directory so a program already installed on the computer can load this data.Usually copying files from one directory into another wouldn't be an issue.
[Code]...
If possible i would also like to change the code i have written so it just loads January2009.txt from the "root directory" of the USB rather than having to specify H: because if i put the USB in someone elses computer this could change to G: and then it wouldn't work.

I require the Login button on the User app to be enabled at a certain time during the day, and the Admin will specify the time. How do I go about achieving this? I have a database as wellDo I save the time in the Database that the Admin enters, and then retrieve the time from the database when the User app is running and compare the clock time on the User app to the time from the database (I will retrieve the time when the User app starts)

I'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.

I have the Timer set at 2 seconds for now. It pulls the data in fine, sets the text for the label fine. But it only shows the last row of data and does not rotate through the rows.

Is it possible to create a windows application in VB to take form input of a text box and put that to a sharepoint server as new list item?I want an exe that when ran, opens to a form with a text box or two and a submit button, that creates a new list item on a sharepoint list.I am using VS 2005 , code in VB. All my google searches come up with stuff that seems to run on the sharepoint server itself, not a program i hand out to people to run from the desktops.I've tried so many permiations of what i found through google searchs and my brain just hurts atm. I'm new to VB + VS, my background is in VBA on Excel, and i have an solution that works in vba, but causes headaches due to macro security etc.

I'm trying to write a small app that finds the local machine's IP address (and SNM, DefGW, 1st DNS server, etc) then displays this nicely.
I don't want to go down the route of doing a Shell "ipconfig /all > somefile" then reading it in as I *know* this can be done another way.
I'm using VB 2008 Express Edition.

I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.
CODE:
When I click on the icon of my program it shows the error message
CODE:
Reporting details: This error report includes information regarding the condition of WindowsApplication1. When the problem occurred the operating system version and computer hardware is use; your Digital Product ID, which could be used to identify your license; and the Internet Protocol(IP) anddress of your computer.

I've written a simple program to hide the taskbar clock and close upon load and I've read a lot of different articles on how to close a program correctly and read a multitude of different answers so I thought I'd just post the code and see if it is written cleanly. Also, I am in the process of trying to get the taskbar to refresh after the hide code has ran and how to refresh it would be great too but is not the main question of this article. I'm using Visual Studio 2008 using the Visual Basic Development settings and I have vista 64-bit. Here's the code:

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.

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.
