Calculate Time From Milliseconds?

May 4, 2009

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,

Get The Current Time In Milliseconds (long)?

Dec 8, 2010

I'm looking for the equivalent to a Java System.currentTimeMilli(), in VB.NET.What is the method to call? I know about Datetime.Now, but not about the actual conversion to long milliseconds.More details about my specific need: I need to manage a login expiration. So most likely when I log in, I will set a "expiration_time_milli", equal to the current time + the timeout value. Then later, if I want to check if my login is valid, I will check is "expiration_time_milli" is still superior to current time.

Make A Mouseclick According To The Time Inserted Into The Textbox (in Milliseconds)?

Oct 19, 2010

just trying to work out some functions, like time delays and such and autoclickers.What I have is two command buttons and one textbox, and what I want this program to do is make a mouseclick according to the time inserted into the textbox (in milliseconds). e.g say someone types in "500", after button 1("START") is clicked, the mouse will click every 500 milliseconds, and button 2 ("STOP") will halt execution. Also, would this continue execution in the background, if i have other programs open? I've been able to make a program that has a timer which ticks at the specified time, I just can't get it to make the mouse click, i've tried "cmdButton.PerformClick" but thats not working,

Get The Most Out Of .NET (when Milliseconds Count)?

Aug 16, 2010

I'm working on a client application (server is out of my control) that connects to a server and exchanges query/command datagrams. 'Milliseconds Count!' according to my project specification, meaning that the more we can shave off a send/receive process the better.

I understand that there are physical limitations like network bandwidth, internet latency, etc. Even so, I have a strong gut feeling that a lot of the latency I'm seeing is directly related to processing; it seems 'out of phase' from the latency of other network operations (albeit with significantly smaller datagrams). IE: A standard 32 byte Windows Ping returns in about 5ms consistently, our query/response datagram (468 bytes out, 1500 bytes back) returns in about 15ms consistently.

I'm also working with multiple threads to speed things up as much as possible at the client side, and it seems the more threads are involved the more latency is generated (I've seen up to 70ms of additional lag when using 3 threads as opposed to 2). In a recent Google I found something that I only glanced at, that said something about a limitation in Windows System Timing where some claim was made that any System.TimeSpan < 10ms was effectively going to be a 10ms Timespan because the Windows System Clock only 'Ticks' every 10ms. I wasn't paying attention at the time, but now I'm afraid it might be relevant and I can't find it again.

Milliseconds Getting Stripped From SQL Server?

Aug 3, 2011

I am pulling a single field from a SQL Server 2008 table and when performing the SELECT in Management Studio, the result shows as:

2011-08-03 17:46:36.997

Now, in my application I'm storing that returned result as a string and using it to later perform an INSERT using it. I notice that after INSERTing into the database, I can see it is being stored as:

2011-08-03 17:46:36.000

Appears to be stripping off the milliseconds and replacing it with 000. In my case, milliseconds are important (sequencing thing)

VS 2010 - Any Way To Add Milliseconds In DateAdd?

Feb 25, 2011

Is there a way to add milliseconds in dateadd? It is not in the DateInterval enum. I created a class so my program knows what the real time is, based off the sql server. This way, we don't have to worry about people's computer clock being off, or different time zones, etc. When the program starts, it grabs the current time on the SQL server, and starts a Stopwatch. Then each time I need the time, I find the elapsed time on the stopwatch and add to the SQL time. The problem is that I use these times sometimes to do timestamps as a unique ID for certain records, and sometimes multiple records get created in the same procedure, so it is being called more than once per second, so the same ID is returned. I need the time to go down to milliseconds, so it is more precise. Therefore, I can't just multiply the seconds by 1000.

Here's my class
vb.net
Public Class RealTime
'Added 11/03/2010 v0.4.4 To determine the real time, not the time on the local machine.
'The time will be stored in GMT +/-0 World Time
Private stopW As New System.Diagnostics.Stopwatch
Private StartTime As DateTime

Datetime Milliseconds Dropped Off Goingbetween SQL?

May 7, 2012

When the Point of Sale program we use makes a change to a row in the SQL database, it automatically updates the ModificationDateTime for that row, and the precision is in milliseconds. I have another column called "LastSyncDateTime, and when theModificationDateTime is greater than the LastSyncDateTime, it downloads the row, finds the column that got changed, does its thing in my program, then updates the LastSyncDateTime with the same value as the ModificationDateTime so it doesn't repeat itself on the same row.The problem is that when it goes back to update the LastSyncDateTime, it loses the milliseconds precision, so the SQL Stored procedure to download new changes doesn't work ("Give me all the rows where ModificationDateTime <> LastSyncDateTime").

Get A Timer That Runs A Process Every 31.25 Milliseconds?

Mar 3, 2011

I'm in need of a timer that runs a process every 31.25 milliseconds. Thus, after 768 "ticks" have gone exactly 24 seconds.The control "Timer" that exists in Visual Studio does not accept decimal values.So I had to round the value of the range to 31 or 32. But this raises a problem since the end of the 768 ticks there is a difference of half a second or more. And I need to run the 768 ticks in exactly 24 seconds.I've been researching, and I read some things about the "High-Resolution Timer. " But I did not understand exactly how to use it, and how to set your interval to 31.25 mils, and do that every period of this interval to run the code.

Resolution Of Milliseconds Component In Now() Object

I have a created a high performance diagnostic logging mechanism that uses a time stamp. It's a print statement gadget that automatically prepends date/time using Now() for the basis of that time stamp. I use the full date and time all the way down to the milliseconds value of the Now() object.

Are there any resolution issues when using the milliseconds component.

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?

Is there a simple way to determine how many milliseconds I need to "Sleep" for in order to "emulate" a 2 mhz speed. In other words, I want to execute an instruction, call System.Threading.Thread.Sleep() function for an X amount of milliseconds in order to emulate 2 mhz. This doesn't need to be exact to the millisecond, but is there a ball park I can get? Some forumlate that divides the PC clock speed by the 2 mhz or something?

Clock - UTC - Give The Users Current Time Zone/local Time

Jul 22, 2011

So I currently have the following:

2 timers

2 labels

1st label is "Clock" this pulls the time from the users current time zone/local time

2nd label is "UTCClock" Which would be UTC time

Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")

Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..
