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.
how trigger an event on specific time of day?
View 2 Repliesi am creating an alarm clock application which requires user input to switch off the alarm. I have 3 comboBoxes on the form named day month year. when the user enters the correct date ( Current date) and click the button the alarm is deactivated. the code to check that the date entered in the comboBoxes is the current date.
View 3 RepliesI 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).

View 6 RepliesI have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If

View 7 Repliesi have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?
View 1 RepliesI 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.

View 9 RepliesI 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 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 wonder is there a way to set a timer for a specific time interval? Lets say everyday between 23:00 and 23:10.

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

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 .
View 8 RepliesRecently 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.

View 13 RepliesI have a form which contains the following :
1. Textbox1
2. Button1
3. Label1
Label1.Text = "Updated Successfully"
Label1.Visible = False
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?
