I have an I/O device with 8 channels. I want to create a timer control for each channel with combo boxes for days, hours, minutes and radiobuttons for AM or PM. This is a crude (and not working) example of what I need:[code]

I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.

The first part (Label 1 + Timer 1) works fine and it counts seconds but I want it to count minutes and hours too.
I have made a new form on vb 2010. I need a small box which updates itself automatically to show the amount of years,months,days,hours,minutes and seconds from the 25/6/09. How would i do this in visual basic 2010?
View 3 RepliesI am building a very basic calculator which adds and subtracts various numbers from various text boxes when I click on the 'button'. This works fine with:
TextBox3.Text = TextBox2.Text + (TextBox1.Text * 1000)
etc but when it comes to adding or subtracting time I get completely lost.Say I want to add 50 minutes in one text box to 12 minutes in another to display 1:02 in a third text box by clicking the same 'button'I am using Visual Basic (in visual studio 2005) to program a Windows Mobile Classic 6 PDA?
I have 4 textboxes Hours, Minutes,Seconds,Milliseconds. When textboxes values are set the count down begins. So far everything works except the milliseconds

Timer1.interval = 100

I use a masked textbox, and I would control the input, the problem is, I use 1 textbox and the control should on the first 2 digits with a maximum of 24 and the last 2 digits with a maximum of 60. Is there a possibility to program this?
View 1 RepliesSo as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I would like to calculate the difference between hours and minutes from one textbox and the hours and minutes from textbox two. What would be the best way to do this? I think DateTime would be the object to use, but wondered if anyone has any examples or better ways?

This Code allows you too countdown seconds and minutes but im not sure how to add hours or maybe even days to it,[code...]
View 7 RepliesI am working on a timekeeping application in VB 2008 and need to show elapsed time in hours and minutes. I have no problem eliminating seconds but if the hours exceed 24 the time is displayed as days.hours:minutes and what I need is to show (for instance) 30 hours and 15 minutes as 30:15 not 1.6:15
Is there a better way then using code like:
strHours = (TimeSpan.Days * 24) + TimeSpan.Hours
strMinutes = TimeSpan.Minutes
strTotalTime = strHours & ":" & strMinutes
Is there a way to tab between the hours and minutes values when the format is set to time in the DateTime Picker? The default action is move to the next control. I have the ShowUpDown set to true. Do I have to set up separate controls, one for the hours and one for the minutes to get this functionality?

View 3 Repliesto obtain double quantity between 2 hours I do this:
[Code]...
But how would it be inversely?For example if I have a number (double), how I know at all the hours and minutes are they?
[Code]...
I have a date value (e.g. 2011-04-11 07:45:00.000) which I am pulling from my database (via Entity Framework). I need to pull out only the hour from the original date value (e.g. 07:45:00), get the current time, and then subtract the current time from the database time value. In pseudo-code, I'm looking to do something like this:
Dim my_date as DateTime = from_db ' This is the value pulled from the database.Dim this_date as DateTime = Date.Now ' This is pulled via a VB.NET function.Dim my_hour = my_date_but_only_hours ' Somehow, I need to strip the date off the my_date Dim this_hour = this_date_but_only_hours ' Same as line above.Dim hour_difference = my_hour - this_hour Response.Write("There are " & hour_difference & " hours left before the time runs out.")
In 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 1 RepliesI 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).

View 2 RepliesI want to display the duration only Hour, Minutes, and Second in data Gridview by Subtract TimeCheckOut from TimeCheckIn in ASP.NET using LINQ to SQL Here is code behind:
[Code]...
In Line 3 in function, Dim dif as TimeSpan = DateTime.Now.Subtract(Duration) which give only the duration of Hour, Minute, and Second from TimeCheckIn until DateTime.Now. However, I want to have the duration from TimeCheckIn until TimeCheckOut only in Hour, Minute, and Second.
I know that the FieldDisplayDuration function is totally wrong logic, but I just want you to get my point only, and also it could be the code sample for those who want to calculate the duration of the employee from the hire date. Finally, Let's get back to TimeSpan by Subtract TimeCheckOut from TimeCheckIn in gridview problem, How can I do that?
Here's the
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Hours >= 1)
If CanTest Then

However, when I change it to 65 minutes instead of 1 hour, it acts up. The time until next question starts going up instead of down... The only thing I changed is 1 hour to 65 minutes:
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Minutes >= 65)
If CanTest Then
If InputBox(Question(Cur), "Question #" & cur.ToString("###,##0")) = Answer(Cur) Then

First i am pretty new to coding and everything so yeah...I wish to make a distance and fuel calculator as my project. Included will be multiple combo boxes with different sets of information (The manufacturer of the vehicle, model of vehicle, the vehicles fuel use per 100Km, its transmission type, users choice of where they will depart from and arrive etc.) Is it possible to achieve this without using a lot of combo boxes? I've experimented using if statements for example:
if combobox1.selected item = "Holden" then
combobox2.visible = true (it's bad i know)
Then from this they would choose their model type in another combo box and then choose their transmission type etc..I don't want to use this because then it will mean i will have to do it for each and every combo box for each and every different set of data because making one 'visible = true' i will have to make the other 'visible = false' and this will cause problems when i start adding a lot onto it.
The user can choose it, like this.
Dom = Sunday
Seg = Monday
...
Sex = Friday
...
So the user will choose the days and the hours for my program open and execute the progress that I programed on the button START, so how to make it start on the days/hours that user wants? Btw the program will stay on the Notification area.
TextBox1.Text = Environment.UserName + "_" + My.Computer.Clock.GmtTime.Year.ToString + "_" + My.Computer.Clock.GmtTime.Month.ToString + "_" + My.Computer.Clock.GmtTime.Day.ToString + "_" + My.Computer.Clock.GmtTime.Hour.ToString + "_" + My.Computer.Clock.GmtTime.Minute.ToString + "_" + My.Computer.Clock.GmtTime.Second.ToString
This produces, for instance, such text in the TextBox1:
MyUsername_2011_2_6_23_22_6
I would like it to displat double numbers for month, day, minute etc, to get something like that:
MyUsername_2011_02_06_23_22_06
How do I do it?
