Calculate The Time Difference Between Two Points In Time?

Jun 18, 2012

I am trying to calculate the time difference between two points in time. I am using: Environment.TickCount.I set a long variable to the Environment.TickCount and then a second long variable to Environment.TickCount at a later point in time. I then subtract the second long variable from the first long variable, yet an incorrect difference is returned.

Calculate Time From One Time To Next

Dec 20, 2009

I've written a lot of code in VB6 and VBA but for some reason, I can't get my head around how to do it in VB 2008 Express.I'm trying to write a program that takes the time distance from an earlier time to a later time, in minutes maybe or even seconds, and use that value to calculate a percentage for a progressbar control.since I'll have multiple events, I will need multiple progress bars. I've figured out how to dynamically add them to a form, and how to update them via a timer. Even learned how to assign an event handler and how to target a progress bar in the array. All is good there but...Well... the parameters for each instance are start time and end time. With those two values, I'm hoping I can calculate where I am between those two points and feed that value to the appropriate progress bar. I just can't seem to figure out how to calculate time values from an input from say, a text box.

I have a text box for each instance for start time, something basic like "11:42 pm" and end time in the same format. Once the timer is started, I want to be able to calculate how far I am from the start time, how far to the end time, and use that to feed the progress bar as to the percentage of completion.Again, I figured out how to add a set amount of controls at run time as per the instances of timers. Of course, I'm only using one timer control to update the form, but using it to process the information and update the progress bars.Later on, I want to use a database to draw the timer data from, but for now, I need to get past this simple hurdle.I THOUGHT TimeSerial would do it for me... going back to my VBA work, you had one timeserial, and another, and you could use the result of one minus the other and then format the result. Even use that number to figure out hours, minutes, seconds. I can't seem to figure out how to do that with Visual Basic 2008 Express.

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).

I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

Time Difference Between 2 Textboxes?

May 2, 2011

I am not sure if I should put in a Text Box or not but this is how I thought it might have to go. Textbox1 shows the start time of a procedure and textbox2 shows the endtime of the same procedure. I would like it if the textboxes were in a 12 hour clock showing an am/pm tag on the textbox's. Then in Textbox3 it would show the differance between Textbox1 and Textbox2 in Hours and Minutes.

I have a value which is milliseconds, I did some experimenting, and with my very limited math skill I came up with this:

Dim val = _Memory.ReadValueFromAddress(hProcess, timer_addr, 4)
Dim seconds = val / 60 Mod 60
Dim minutes = val / 60 / 60

I don't even know what will happen when the hour counts down,

Calculate Time When Using DateTimePicker?

Apr 8, 2011

I'm new to VB and I'm so confused when using DateTimePicker. To be more specific, I have 2 inputs and two of them are Booking Start Time (BST) & Booking End Time (BET) (using DateTimePicker and set them as Time ). I should allow users to choose any time (including Minutes and Seconds)for BST (just need before than now) and BET. BET must be greater than BST at least ONE minute, but still also ensure it less than now (else it should appear a message box to tell specific problem). Then,system will calculate how long it is.
