I have a problem in detecting the 30 minutes interval in time scheduling like for example i have a combobox(starting_time) and combobox2(endtime) and I select there 9:30-10:00 it has 30 minutes I want to show a message box that I should be 1 hour.

For Each x In ListBox1.Items
Label1.Text = "Status: Loading IMDB page..."
Dim str As String = x
Dim MOVIESNAME = str.Substring(str.IndexOf(""c) + 8)
[Code] .....
Is there an option to set a time interval between each check? Because it will load the page (it's not google, it's my personal website with some information needed) and it need to be fully loaded till it gets the information then it would do another check for another listbox1 item. Like.. maybe 5 to 10 seconds is enough..

have another problem regarding with time again. After getting a user input time in "H:mm", in what way can I add like an additional 15 minutes to it? Something like this:

View 6 RepliesI have a question for the well versed among you. I have done some research, but didn't seem to find the exact answer I was looking for. So without further adieu.Given an event which needs to occur at a very specific time, whats the best and most predictable way or making that happen.
A: Use a worker thread, and threading.thread.sleep(TIME).
or B: Use System.Timers.Timer or System.Threading.Timer to execute in (TIME).
NOTE- I am fully aware that any of these will work. My question is in regards to priority of execution. How will a timer, which I can't figure out how to set a priority on, compare to a thread with a priority of Highest or even Real Time. Microseconds DO count in this instance.
I once saw in an app a control that allowed the user to choose when they wanted the Timer running. It looked something like this: And when the squares are green, for example Tuesday 3:15 AM - 4:15 AM, the timer would run during that time period. I'm curious as to what control will allow me to do something similar?
View 3 RepliesI would like to run a code every 1 minute ,15 minute etc Is there any better way than following put in the timer control with time interval 1 sec. A c# solution is also ok.

What would be the best way to run a subroutine over and over again every X seconds. I want to avoid creating an infinite while loop to do this because this sub needs to be called repeatedly while the rest of the program is still active and responding.

View 7 RepliesI am using Visual Basic 2008 for a Windows Form application. I have a PictureBox on the form that I need to display a series of 12 JPG files, one every four seconds. For the life of me, I cannot seem to figure out how to get the Timer control and its Click event to work.
In pseudo code, I need something as simple as the following:
1. show JPG #1 in picture box
2. 4 second delay
3. show JPG #2 in picture box
4. 4 second delay
etc.
I have a Timer on the Form set with Interval = 4000. I have a PictureBox. I have all the images in the Project. I am embarrassed to say that I have spent 4-5 hours searching the Web for sample code or something helpful, but am still stuck.
All the elements are there. It's just a matter of understanding how to pause the image displayed in the picturebox for 4 seconds before moving onto the next image in the series.

I have a quesion about using the timer1 function. I am a complete virgin when it comes to programming, so please be kind. I have a project that is using an NCD relay controller to control linear actuators. I want one relay to turn on and then stay on for 10 seconds and then turn off. I set the timer1 properties to enable with an interval time of 10000. I am programming a button to turn on the relay then wait 10 seconds then turn the relay off. All that happens is the relay comes on then off immediatley. I have tryed to do this several different ways with the same results. It is though the timer1 is not getting recognized. So my main question is, what steps am I missing, and how do I get a delay of 10 seconds before the program recognizes the turnoffrelay command?

View 2 RepliesIn Microsoft Access I use: Hours(time) minute(time) function to get current time hour and minute. I then use loop to add to the minutes until it ends in a 5 or 0 to round it up to the next 5 minutes. e.g. 13:43 rounded up to 13:45 I use IF statement to make sure the minute does not exceed 60 to start the hour. I want to use that time to add hours or minutes to easier e.g. add 15minutes, add 1 hour ect.

View 4 RepliesWhat is the best way to schedule task on VB.Net application? I have searched this forum and google but I still need some more comments.There are two ways that I've found so far:
Command Prompt By using AT or SCHTASKS command. My Windows 7 seems to recogonise both Command. May I know is there any significant different between this two command?
Timer By using Timer function, but I'm not sure whether is this a good method as it might slow down my program by constantly checking. May I know by using the above method, can I retrieve the scheduled task and display back in my program with ease?
I am writing a program and have run into an issue. The program requires a conversion of time (e.g. hours,minutes,seconds) to a hexadecimal value of no more than 4 bytes (e.g. FFFF).

I have an application that I need to automate where at a certain time each day, say 6pm, it will run a certain method(which is to check a database for key terms and then access the api to search for these terms). But there is also another process which is running all the time accessing the stream api so when the search is complete, it interrupts the stream and hands over the new terms.
Now I thought of adding the .exe file to windows task scheduler but not sure if that would work. The stream method run indefinitely and at 6pm each day another process needs to run. I thought of using the system.threading.task TaskFactory but when I include it, it shows taskfactory as undefined. ( I do have .net framework 4.0)If it launches using the task scheduler as 6pm with my code logic as follows:

I have a Windows vb.net project that does an occasional "auto refresh" based on a 20 minute timer. I want to avoid any type of auto-refresh... if the user has manually had any interaction with the program (mouse move, click, keystroke, anything) in the past 5 minutes.
I added a global variable "Dim g_LastActivity As Date" so the timer can detect that 5 minute mark.
Is there some place to put my "g_LastActivity = NOW" line that will ensure it will happen during ANY user activity? All mouse clicks, on all buttons, all mouse moves, anywhere, all keystrokes, basically EVERYTHING.
I am looking for formula that is accurate in converting Minutes to Decimal Minutes i.e 30 minutes is 50 Minutes in Decimals so 1.3 hours is 1.50 and not 1.5 i have used Minutes/60 but it is not accurate as some times i have to Multiply the result by 100 and some time 1000 to get correct results based on single digit Try 1/60, 10/60 99/60 or 100/60.What would be the most efficient and correct way to Convert the time into Minutes ?
