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.

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,

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,

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..

VS 2010 Comparing Current Time To Stored Time?

Mar 27, 2011

I'm writing a report scheduler that is somewhat of a clone to the backupexec scheduler and the layout can be seen in post #10 here: [URL]..It works great and saves/edits/deletes records just fine, but now i need to compare those records one at a time in a windows service that i'm writing in order to trigger automated report creation and emailing - i already have the report and i already have the code for the emailing, i'm just looking for the most efficient way to loop through the table (that i've pulled in to a dataset) and compare its records with the current date and time - if true, the event fires.

[Code]...

1stSun, 2ndSun etc are bit fields, time is a datetime, and the remainder are varchar. My service checks the database every thirty seconds.The english version of what i'm trying to do is "Connect to the database, grab the entire table (it will always only have 5-6 entries max, so i felt 30 second sweeps was okay), and If today is the 1st Sunday of the month, and it is currently 11:00:00 a.m. (could be any day or time, this is just an example) - loop through the dataset to identify if any records match the time field or greater - if they do, fire the report

FileOpen, And FilePut For A Long Time In .NET?

Apr 1, 2010

I've been using things like FileOpen, and FilePut for a long time in VB.NET, and it's never presented any problems. However in my latest project I'm using CodeDom to compile at runtime, as you know FileOpen, and things like that are the old VB6 methods, such as MsgBox("Msg"), and these don't work. So I need to know how to do this using only the newer VB.NET code.

Run Time Error During Long Loop?

Dec 7, 2011

I wrote a program which loops through a very long CSV file (50 meg) and parses the data as it goes.Sometimes, the program aborts and I get the following message:The CLR has been unable to transition from COM context 0x37a090 to COM context 0x37a200 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

I know its going to take a while. There are several hundred thousand lines of text in the file that this program is reading. I am not sure exacly waht the message means, but my program seems to work fine other than the message. odd thing is sometimes the message doesnt always pop up..

DateTimePicker Control Set Time To 00:00:00 Instead Of Current Time

May 12, 2010

I have a form with the DateTimePicker control on it. When I select a date it gives a value like "date time" (Eg.: 5/12/2010 12:20:35 PM). But here the time returned is current time. What I need is for the date chosen from the picker automatically set the time to 00:00:00 instead of the time when the date was picked.

.net - Very Long Build Time In Visual Studio?

Oct 28, 2009

I've a solution with 15 projects (14 class libraries and one web application). Each class library has corresponding test project (i.e. if I have MyApp.Services project there exists MyApp.Services.Tests -- using NUnit). Everything is written in VB.NET. The problem is that when VS tries to compile any of *.Tests project it stops responding (the bigger the project the longer the period without reposnse). I don't know where to start looking for an issue. I'll add that I've R# 4.5 installed.

UPDATE 1:Is there any way to benchmark a build in visual studio? To get build times for every project?

UPDATE 2:It seems that there is no difference after disabling R#.

Asp.net - Website Hangs For A Long Time Then Displays Nothing

Mar 10, 2009

Occasionally, my website will stop functioning and anytime an ASP page is accessed, the browser will hang for many minutes before bringing up a correctly formatted HTML page with nothing in the tag. It seems to happen whenever more than one person attempts to access an ASP page, but I'm not positive it's isolated to those conditions.

Let me emphasize that the issue does not arise when accessing directories/HTML pages/other files. Only ASP pages are the problem. I am using lunarpages as a host.

VS 2008 - Anyway To Time How Long It Takes A Message Box To Pop Up?

Sep 9, 2009

I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:


[code]...

this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?

Inline Aray Initialization Is Taking To Long Time?

Jul 6, 2009

I am on one asignment of convering C# to VB.net and stuck up with this problem.C# application has one class having inline two dimensional array initialized with size 168X168. I converted same class to Vb.net. Now whenever I create instance of my this VB.net class, It take almost 3 minute.

To figure out problem, I put break point on sub new() (first line of my constructor), and behaviour is realy strange because it takes 3 minutes to reach at first point of my constructor.Whenever I comment out my large size array initialization code, It works perfect. Now please note that same code is working fine in C#. It is not taking even few millisecond to initialize that class.

AXWindowsMediaPlayer Taking A Long Time To Release File On Close

Aug 29, 2011

I am writing an application for managing mp3 files. I use AXWindowsMediaPlayer1 for playing files and UltraID3 for reading and writing ID3 tags. Every time the user selects to switch to next song, the ID3 tags of the current file need to be updated. My problem is with Media Player taking a long time to release a file for access after doing a "close". Currently I need to add a 6 seconds delay between the "Close" method of the media player and the ID3 tag "Write", otherwise I get the error saying that the file is currently in use. Anything less than 6 seconds does not work...

I attached a short version of my application which focuses on the issue.

Keeping Browser From Timing Out In Mvc3 App During Long Processing Time

Mar 14, 2012

MVC3 vb.net. In my app I have a point where 500+ emails with attachments are sent out using a for each loop to accomplish this.. Nothing is returned to the browser the entire time this is running so eventually the browser think it has timed out... I tried just having it redirect to another actionresult function after every email and that function just passes it back to the email function. This is not working and I feel the reason is that nothing is actually being sent to the browser window its self.. Is there a way to fix this issue??
