I have an app that relies on a database. Basically, users are checking in and checking out items and the database keeps track of all that.My boss wants a notification system to email us when a item is overdue. I already have most of this figured out.I was able to create a service and have it read registry values that the app sets and then it reads the check outdate from the database. If it's overdue, an email is sent out.
But, I've only done testing for 10 seconds at a time. I'm currently using a System.Threading.Timer to run every 10 seconds. That was only a test, it won't actually be that way.Instead, I want the task to run once every day. I was thinking to just have it run every hour, but if it runs every hour, then we'll be constantly bombarded by emails when an item is overdue. And sending it every "x" hours brings it's own issues and isn't ideal.Normally, I'd run a task via the Windows Task Scheduler, but the app has to read the database. I guess I could create a separate app and launch it via the task scheduler, have it complete the tasks and then close when done.
I'm wanting to create a small application that will allow me to schedule a machine to shutdown at a specific time. Any suggestions on how I can make this .exe run at a specific time besides using the Task Scheduler?
I need to have a windows service that capable of monitoring constantly whether my application is running or not. If not, the windows service will RUN it for me.
I find it hard to manage tracking my time on multiple taks..esp when it comes time to charge How would i track time? ie if i click on a start button, then click on a stop button...how would i work out diff in hour mm secs....
I want to verify if the current system time falls within the specified time range between 7:30pm - 9:00pm. If it falls within the specified time range then display a message.
what I would like to do is create a program that runs in the task bar next to the time. What I want this to do is listen for the key stroke combo of CTRL-ALT-T no matter what program they are in. When they hit this key stroke I want the program to do is hide the task bar on the bottom of the screen. you know how you can change the hight to two rows one row and so on but you can also drag it down so it has no rows and can't see it. Then when they hit CTRL-ALT-T it will then display the task bar with what ever the hight wa set to. Just don't know what direction to go to do this.
I found some great code on capturing webcam images but the problem is the client PC will need to initiate the communication to this server (click Connect to server IP). This is like 2 way communication.How can i do something like this (door Kiosk system):when a visitor press a button on the LCD that come along a web cam (this will be the server), it will send the signal the client PC that is installed with the application i've created (window form) and pop up the images to the client PC (more like a 1 way communication). This image is captured through the web cam on the server to capture the visotor's image waiting outside of the door. How to do this?I'm really stuck as i'm not familiar with window API programming yet.
1) how to do the mentioned 1 way communication? possible in .NET?
2) how to make my application to be at the tray icon just next to the time displayed on the right bottom corner of the task bar? When a visitor press a button o the server, it will pop up a window form on the client PC showing the image captured via the server's webcam outside of the door.
I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.
How does one check to see if the system time is equal or not equal to a specific time? So, say I want to perform an action if your system time is between 6pm and 6am. Or something similar?
is it guaranted that a task A started before TaskB will be completed before task B assuming the task do the same level of operatons?or in other words is there a chance that a task B will finish before tast A in the assumption that the task calls the same procedure?
I am aware that if you wish to run a program at a specific time, the best way is to add it to the windows task scheduler. I have a forms application that accepts as input a text file and some button selections before the actual main runs. Can this kind of program be scheduled? I realize I would have to hard code the inputs but does .net have any features to access the task scheduler?
I am writing a small app to automatically connect my PC to the internet at a certain time and I am using rasdial.exe for it...
Private Sub SetIt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SetIt.Click Dim windir As String = Environment.GetEnvironmentVariable("WINDIR") Shell(windir & "system32 asdial.exe", AppWinStyle.NormalNoFocus) End Sub
My question is how to make the shell function run at a specified time or after a certain interval?Also how to wake up my PC from hibernation using vb and winresume.exe
I have a simple WinForm that is using a Tab Control to simplify data entry. The very last page has a text box that allows the user to "set a name" for the file. I really want to simplify this and suggest how the file should be named. What I want is for when the tab page is entered (consider that generically) that the text box is pre-populted with a name.
This code will do what I want, but only the first time the tab page is entered. what I am apparently missing or a better way to do this?
Private Sub TabPage6_Focus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabPage6.Enter ' This should simulate a load event modGeneralInfo.docProductNaming() modDocGen.docNameShorten() End Sub
how to start a VB.NET program at a specific time of the day, but I simply cannot find it. I've found an example that shuts down the computer at a specific time of the day, but having no experience with the Timer function, I wouldn't know where to start when hacking the code.As an example, I'd like the program to run at say 2:00PM and display a message. The displaying the message won't be hard (MessageBox.Show("Stuff")), it's just the starting .
I just decided to recode my personal alarm program from scratch, new functions, ui etc and optimize it but I'm stuck on a part.
I have the option to start an alarm and set it to expire at a specific time, say in 2 days 5 hours 18 mins 10 secs. I was wondering what would be the best way (performance wise) to achieve this.
Recently in a couple of my current projects I have found that I have the need to 'schedule' events in my applications. For example, I would like something to happen in my program at 11 PM every day (and no I dont want to use Windows Scheduled Tasks) but I cant think of a good way to do this... The only method I can think of is to just have my app check every minute to see if the current system time is 11 PM but obviously that is pretty rubbish. I considered using Windows WorkFlow but that seems very overkill just to do this one thing...
Oh and if it makes any difference, I would like the user to be able to modify these times that certain events occur.
I need to convert the current date to unix but if I run my app in europe or in the US, I need to get the same unix time.To converto to Unix is not a problem, what I can't get it working is how to set the convert the curretn date and time to a specific timezone before converting to unix.

Is it possible to shut down windows say if the time is around 6:00 pm using the VB.net code. has any one done that. I have the code to kill my program when it is after say 6:00 pm, I would like to shut down windows along with it. I can post the code for killing my program (actually I got it from here) if anyone wants it.
Now what I want to do is, when I Enter something on Textbox1 and click Button1, Label1 should be visible and blinking.
Label1.Visible = True
But, when I type something on Textbox1 again (before even hitting Button1), Label1 should not be visible anymore and continues this way.Another way is to make Label1 visible for a specific time, say 5 seconds (blinking) and goes invisible. I prefer the first one though I would love to learn both?
How can we schedule a windows service to run at specific time ( lets say every day morning at 6:00 AM )
For this i had a timer thread to sleep for 24 hours like below and start the service exactly at 6:00 AM ( but the requirement is.... no matter when the service starts, but it should run at 6:00 AM .... So how to do this )
Bottom Line : How to schedule Windows Service to run at specific time ?
How I can use a messagebox to show for a specific amount of time only? So if I place this in maintimer, MessageBox will show and will auto close and I set how long it must display for. If messagebox is up, then Timer is paused. I did research around these lines but couldn't find what I'm looking for.
