I'm currently coding a small app, and I got sort of stuck when I had to convert from seconds to HH:MM:SS. This is the "solution" I came up with so far, but there's a small problem with it.
Code:
Public Class Form1
'Accept amount of seconds
Public seconds As Integer
[Code]....
The code works fine if the amount of seconds is 3600 (1 hour) and under, but if its above, it doesn't really work.

I have a masked textbox (dd/mm/yyyy hh:mm:ss) and a textbox (hh:mm:ss). I want to calculate the difference of them both and put the result in an other masked textbox (dd/mm/yyyy hh:mm:ss).e.g.13/11/1979 10:00:00 - 15:00:00 = 12/11/1979 19:00:00..I already tried Date.FromOADate(CDbl(dec_time) , where dec_time stands for the difference between first and second part of the equation.
View 3 RepliesI am trying to make a program in visual basic 2010 where the user enters hours minutes and seconds into text boxes and then the program will count down from that until its equal to 0 when a msgbox appears and says its finished. I was converting hour entered, minutes entered, and seconds entered all into seconds and then having a timer subtract 1 from that until its equal to 0. But the problem I'm having is that I want to display the hours, minutes and seconds left in a label to the user in a format of: "hours: 0 minutes: 23 seconds :42" but how to display it in this format.
View 2 RepliesI want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.

Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?

I would be very grateful of any insight/resolution of the following issue I need to overcome.Using VS/VB2008 Pro/SQLExpress - all running on XP, I am building a WinForm Application (a Quotation application for Landscape Designers).48 Bound controls on my form work perfectly with DataSet and Tables when Updating any user changes to controls on the form to variables that determine price/cost of work being quoted for - providing the DataSet has already got values in it; Delete also works fine. However, although the "AddNew" (on form's BindingNavigator) works, it takes 30 - 35 seconds to add a new row. Table contains 10 rows and 45 columns. This is unacceptable and despite most of this afternoon reading forums, searches etc, I have failed to find a solution to an issue that I cannot believe appears to be so infrequent. Clearly, it is something I am doing or not doing.
I have searched via Google, crawled over MSDN pages, read/searched some of the standard textbooks on VB 2008 and looked (again) at Beth Massi's Data-related Forms over Data video series. I have re-checked the properties for the TableAdapter/Manager on my Form. I have used the wizards to create the necessary Select etc clauses. All runs as required except when user needs to add a new row (aka "New Quotation")
I was wondering if it's possible to add seconds to a clock in vb.net. I mean lt's say I have a label and I assign it to DateTime.Now(), how would I show/display the time with the seconds "ticking"?

I have intger that represent time, but are not time values. So I have a MIN as int = 5 and SEC as int = 25. And I want to subtract 30 from SEC.
In normal math I would get -5. But this is time, so my MIN should be 4 and SEC be 55. Is there a formula for this already?
I know it would be easier if I was using DateTime, but that is not a option. I'm locked into using integers.

View 4 RepliesMy Windows Forms Application has a WebBrowser. The program check the source code of the webpage (monitoring the changes) in every two seconds. I use a Timer:

I have a windows form application that will open other forms, but will only display the forms for a few seconds (user configurable). I would normally do something like threading.thread.sleep(n), however when doing this the forms controls do not load only the white background shows, and I have also been reading that this isnt the best practice for what I am after as user input will not be actioned until the thread wakes up.
I have come across people using System.Timers.Timer(n), but I am struggling to get this to work for me, the form will only open and close straight away (you can only see a flash as the form opens then closes).
The code that I am using is:
Private Shared tmr As New System.Timers.Timer
aForm.Show()
tmr = New System.Timers.Timer(aSleep * 60 * 60)
[Code].....
This is all contained within a Private sub that passes the form and the defined run time.
My intention is to have the main application running from the task bar, which then calls one of the forms that will display for a defined period of time, close the form, then call another one of the forms.
Is any able to point me in the right direction for why the form opens then closes without seeing through the defined run time (I have been testing with 10 seconds), or is there a better way of doing what I am seeking?

View 6 RepliesI have been searching the internet and this forum for the answer to my problem, but so far nothing is working. I want a label to appear 10 seconds after the form loads. This is one of the codes that I have tried so far [code] it doesn't work. Like this the label is visible when the form loads and then disappears, but if I switch the Label2.Visible = True & False the code doesn't work at all. It also doesn't do anything if I change the = to a less than sign.

TimeN is system time. TimeF is a fixed date and time. All I need is the number of seconds between fixed and system(now) for timeR (and counting).

View 8 RepliesCurrently, I have 4 textboxes displaying hh , mm, ss and ms.I am required to convert only the Seconds, Minutes, and Hours and display it into another textbox (see attached doc for diagram).I've got a brief idea that for the hours, i'm required to multiply by 3600, and as for the minutes, multiply by 60. Am i correct? Please correct me if i'm wrong. But as for the actual coding of conversion and how to display it into another textbox, i'm not sure how to do so.
