to 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]...
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?
Ok so I want my program to keep sending a messagebox pop up at a speed that the user can pick for as long as they choose such as."How many hours" 5."How many minutes" 10..Then that will countdown every minute.[code]

The first part (Label 1 + Timer 1) works fine and it counts seconds but I want it to count minutes and hours too.
I 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 7 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 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 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?

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.
