Remoted DateTime Values Can Not Be Converted To The Equivalent Local Time Of A Remote Computer That Is In A Different Time Zone
Aug 24, 2011
I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.
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..
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?
I am doing work on a new logging database that I have decided to use UTC datetime to store all datetime values since our company spans timezones and multiple sources and timezones are logging events.However the problem that I cannot get my head around is formatting the datetimes in my datagridview for my user application.Our applications use mostly LINQ to SQL to manipulate our data from generic SQL CRUD calls, so I am hoping I can mask/format the DGV to get the conversion or some LINQ function rather than having to write special SQL stored procedures to do it every time I need to display the data.. (I have found multiple sources that explain how to do that)
I am trying to set up an "AT" job to export some registry keys on a remote computer, the problem is that DOS command requires a time to run. I want to get the system time of the remote computer so i can schedule it to run 1 minute from the time i send the command.
Is there any way to get the system time of a remote computer with VB.Net code?
I would to create an application that will allow me to monitoring in real-time the screen on a remote computer, I dont want to keylog, or control mouse,ot keyboard, just watch what they do at real-time.
I have been dabbling in VB before and i played around wiht linq to sql back then but im wondering what i should go with here.I need to have a list of people.. They should all have their own id nr.
The people in the list are supposed to keep a record of values changing over time with a datetime stamp. (In my case its numbers from a test outcome of blood)You have to be able to add people and delete people. All records will be deleted too.A Chart will read information from the records and display changes over time in chart.I was thinking of doing it with linq to sql and i was kinda aiming at Creating datatables with id names from the script
Havent found a way of creating datatables from a script though..I was hoping for a solution like that.. And i was hoping id be able to search databasetable names.
I need to copy a file from a local computer to a remote computer on the network, if i try to use File.Copy without logon i get the following error:"Logon failure: unknown user name or bad password."How do I provide user name and password for file copy?
How do I change the time zone using VB.NET 2.0? I found an article explaining how to do it in VB6 [URL] but I can't adapt it to .NET 2.0 - I just don't have enough expierience I guess.
I have a program that reads a file with Pacific Daylight Time, I want users to see the time and date in their local environment.
At present I have in Australia a time difference of 18 hours, so I have a list box with -24 to +24 and currently set at 18, my code is elementary as long as I have moved past day one of the month it suits me personally, but I want to distribute my app, so I need something better.
I'm trying to write code in .NET 2.0 to change the time zone - long story short its toautomate server deployment. I'm having a problem adding the SE_TIME_ZONE_NAME privilege I found code online to add the SE_SHUTDOWN_NAME privilege which I adapted into the following code:
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?
Basically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.
I can get the local computer name on a RDC session using Environment.GetEnvironmentvariable("ClientName") if the application is 32 bit and Server is 32 Bit or when app is 64 bit and server is 64 bit
How can I get the local computer name from a 32 bit application when the server is 64 bit
Environment.getEnvironmentvariable("ClientName") returns an empty string
I have a VB.net 2008 Windows forms application which runs on W2k3 server and is accessed by 15 Remote Desktop users I would like to be able to store information such as the default printer for each RDC session plus other info To be able to do this I need to know the local computer name (or some other identifier) so I can store computer specific information (such as default printer) how I can get info about the RDC session from VB
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
In my last "Question" today Re-ComboBox", I was told that I can add the actual TimeZones into the ComboBox using the following; ComboBox1.Items.AddRange(TimeZoneInfo.GetSystemTimeZones. ToArray) I was able to get the ComboBox filled with those information. However, I'm facing a problem in using those information for my "Sunrise Tme" program.
My problem is : I need to add the "Time Zone" (is declared as Double) - which I select in the ComboBox - to the Calculated Time (in GMT). I am unable to get the Value added to the GMT, ie the Value such as 2.5 or 5.5 or 6.0, because the information in the ComboBox is of several Data-type. Keyword such as "CDbl" didn't work. What mistake am I making?
I am having problem with the date time. I am getting the time from the server in xml, when i try to assign the date which i get from the server to date variable it automatically converts to local time. Is there any way to prevent this conversion.
The converted project takes too much time to load than previous vb6 project. What manual changes to the code should be done or is there any other option. Is it due to vb6 to vb.net conversion.
I'm trying to develop a windows application where i can get connected to remote server and look for process state going in remote server.We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.)
So our aim is to develop a windows application where i can get connected to that servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)
The UI at left side should will have list of servers i can connect to. When i get connected to server, at right side of UI, i want to display the status of installation (In progress, failed , completed).
why did they make this so hard to do. Does anyone have any clear cut, basic 3-4 lines of code that can tell me how to add 2 time variables together to create a 3rd variable? I tried this but on Time2 I get Value of type 'Date' cannot be converted to 'System.TimeSpan'.
I want to filter my results with respect to date and time....I have date stored in a separate field which is of datetime data type...Another field stores Time value but as it is a datetime data type so it stores current system date along with the entered time. Now when I filter results using date then it runs well and shows the results between specific period like between dates from 12/10/2011 and 12/15/2011...But when I want to show results with respect to time it doesn't show any results...
I am using dataadapter and dataset for retrieving records from the sql server database... Please tell me the solution for comparing time value taken from the textbox with the datetime value stored in the database so that i get results between specific time like between 12:00 pm and 6:00 pm.
Actually I have datetime value stored in the database. What I am taking from the textbox is a time value. I want to extract those results from the database which are between the given time value....To be more concise, my application is a booking system for a sports club and provides an option to view alreaady made bookings.. Here i offer two options either to view all bookings for a specific game or to filter bookings. In filter bookings one option is to filter through date and time...Date option is running okay but problem lies in time part...I provide two times but unable to view bookings between them...
My code is:
Dim prmtimefrom As New SqlParameter("@booking_time", SqlDbType.DateTime) prmtimefrom.Value = TextBox3.Text Dim prmtimeto As New SqlParameter("@booking_tim", SqlDbType.DateTime) prmtimeto.Value = TextBox4.Text
I get unexpected results when I use DateTime.ParseExact.
Here's my test code:
[code]...
It looks like it's because the day is systematically added by ParseExact even though I only specify the time in the format. My question is: How can I read just the time with DateTime.ParseExact?
So I'm kind of new to VB and am just playing around with a little project, I currently need a loop that is constantly checking the systems clock to see if it's equal to a certain time.
While Not myTime.Hour = 24 If TimeOfDay = newTime Then nfi.ShowBalloonTip(15)
I need to obtain time values from a SQL DB. However, I was able to set the datatype for the respective column in the SQL table only to "datetime" as there is no "time" option in the dropdown list in the Visual Web Developer. Namely, I want to bind a Listbox control only to the time data (i.e. not to "dd-mm-yyyy hh:mm:ss"). I tried to convert the datetime values to string and then extract the last 9 chars that refer to time.Unfortunately, my attempts to do that with SubString have failed:
I am exporting data from an sql table to an excel spreadsheet in Visual Studio 2008. There is a field that is date/time that I only need the time part of (hh:mm). I am using the Convert command to do this, but I am getting the error 'Undefined function Convert in your expression'. Is there another function I should be using? Or am I missing and Import command at the top?Here is the code (field TimeofFall is the one I am having trouble with):
I have two datetime variables in VB.Net [code]I want to add both these variable in single DateTime variable , i didn't find any .Net function to do that.Is there any other way to do it?
