How can i calculate time duration between sunrise and sunset? Then how can i divide this duration(sunrise to sunset) into 8 equal parts(Hr: Min)?
All i need is starting and ending time of every part. And i want to write this code in VB.NET because in VB.NET i can easily design the GUI.
I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

View 1 RepliesWe have create a VB.NET app (exe) that is called by our non-vb.net software app.The .NET app is a Windows Application module. The only form presented on it is when users are previewing a Crystal Report.Otherwise, we are just executing code from the module. What we want to do is set the cursor to an hourglass from the moment our vb.net app(exe) is executed until it has closed.I have tried entering Cursor.Current = Cursors.Wait as the first line in the code, then Cursor.Current = Cursors.Default just before exiting the Main subroutine. But, this does not work.
How can I control the cursor on, essentially, a non-form vb.net application?
according to the formula given by DdoubleD i resolve DSS audio file duration problem, but this time some dss file is more compressed and duration of these file different according to size of file. IS there is any technique in .net 2005 so that i can include any third party's player and find duration and other thing I tried to include DLL of these player but not compatible with .net..DSS file is basically dictation by doctor(olympus recorder is use to record dictation and it save these file in .dss format) I already included WMP.dll for MP3. But .dss is creating problem.
View 1 RepliesA simple class that plays a tone of varying ampliture, frequency and duration through the PC's speakers:
Imports System.IO
Imports System.Media
Public Class Form1
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Beep.Beep(1000, 1000, 1000)
[Code]...
This class uses SoundPlayer.PlaySync which has a 4 MB stream length limit, so the longest duration is 24000 milliseconds. You can try SoundPlayer.Play for longer durations, but allow plenty of time for it to complete.
I have created my own application for organising my video library. when the application starts a datagridview displays all of the videos in my database. i can't get it to display the duration of each video. i assumed i'd be able to loop through each row in the datagridview and use the FileInfo class to look up the properties of each file and get the duration from there because if you look at the properties of any .avi and then click on Details you can see the duration of the video but i can't figure it out.
View 6 RepliesI have an MDI form in VB.nEt where I have to find, if the application remains idle for 20 mins, I got to log off the logged in user. On doing RnD, I found a class that helps us do the same :- http://blog.perfectapi.com/2008/05/detecting-idle-state-in-winforms-apps/
I saved that class in my applicaiton. In my mdi form's Form Load created an instance of that class. Now I don't know how to move ahead i.e. how to find that 20 min lastActivity duration. I belive I got to trap some evcent in my mdi form and find the value of lastActivity and if that is >= 20, then logoff. But which event to trap and how, I have no clue. In the events for the from also, I didn't found any useful.
I made a media player and it works well but the duration tag says
00:00 and that's not right heres my code:
[code]...
I have been searching around and trying to figure out how to get media, specifically videos, length/duration.I know that you can use the Windows Media Player object to achieve this, however, I need to get the duration of some media that is not supported by windows media player.I am developing my own media player in VS 2010 that will be utilizing the VLC media player component since VLC is able to play most (if not all) media formats. So far I have tried playing around with "My.Computer.FileSystem.GetFileInfo("path").length" but all this gets is the media's length in Bytes. What I am trying to achieve is the format of hh:mm:ss for pretty much every format, not just Windows Media Formats, but real media, .mkv, etc.

I've found solutions to determine the length of an audio file using WMPLib.WindowsMediaPlayer (which seems quite ugly), by using a physical file path, but nothing to determine the duration of an audio file stored in a VARBINARY field (SQL Server 2008 R2).I'm using .Net WebForms. Maybe it'd be a better idea to do this client side with jQuery, but what if I only want to expose some controls to the web browser based off of the duration?
View 1 RepliesI made an mp3 player for fun, and I want to add a box that shows the current time of the song and will continuously update every second while playing. I wrote a do loop that while the song is playing will get the current time put it into a listbox or textbox, then sleep for 1 second and then loop again. Using a textbox it will put the first time in, using a listbox while the song is playing the vertical scroll bar keeps shrinking so it seems as if it is putting all of the times there but I don't see anything at all but a blank listbox.

View 1 RepliesI need to find the duration of a video file. I am not talking about this. LenOfVideo = AxWindowsMediaPlayer1.currentMedia.durationThis will give the duration of a video when it is playing, I want to know the duration of ALL the video's in my List of video's so i can display it in the selection for the user. The currentmedia.duration will only give the duration when you play it and i have about a 100 media clips to play..

View 13 RepliesI want a proper hh:mm:ss formatted duration, but I cant seem to get it right. I have ran through a good dozen attempts and things just arent working.
timer
Public dtStartTime As DateTime
Public tsElapseTime As TimeSpan
Public Sub tmrStartTime()
[code]....
Calling tmrStartTime sets the start of the timer, and tmrGetTimeSpan should report back the proper hh:mm:ss. For example, 11 elapsed seconds should look like 00:00:11, or 65 elapsed seconds should look like 00:01:05.
I have an application I'm currently working on that requires Administrators to be able to track the views of a ticket and it's duration.I've got the tracking of the number of views by users sorted out, I have a table that contains a TicketID, UserID and a DateOpened. Each time a user visits the page, a new row will be inserted.However, the way I would like to track the duration of views is by having a DateClosed field in the table which will allow me to work out view duration in the code as opposed to storing the time directly.
I can't use Google Analytics or anything Third Party for the task either due to internal policy as it's an intranet application.What would be the best way to achieve filling this field on page exit?
I am using VB 2008. I am trying to use the currentMedia.durationString to get a tracks lenght like shown below:

The maximum value that works for AutoPopDelay property of ToolTip is 30 seconds (30000 milliseconds). Any values greater than this maximum will be defaulted to 5 seconds (5000 milliseconds).[url]...

Recently I've been into PBX call accounting programming on VB.Net 2010. My results are way too successful including friendly user-interface and connection datareceiving coding. Except for one. That is the call duration of calls, incoming and especially those outgoing. In my project I didn't use any API (like TAPI for PBXs) thus is there any option how to detect the state of the outgoing call, whether is still ringing, ended without answer or answer at some point of time...because in my project nevertheless what call state is being processed, I'm getting the total call duration from the moment that call was initiated to the moment is being finished or not-answered.
Here is a sample of my project where the DataReceived event is fired whenever there's something to parse from PBX to the PC.
Programming language : Visual Studio 2010 Ultimate - Visual Basic .Net
Database : Microsoft SQL Database
PBX Machine : Panasonic KX-TEM824
P.s. If you need to provide some code I'll post a sample of my project where the DataReceived Event is being handled.
