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 am trying to create what I am sure is a simple program to add hours to convert UTC time. I want to type in a UTC time and have it convert for every state in Australia. [Code] Now that works fine however when the conversion goes past "midnight" it then shows the date and time. I have tried about 50 different things but cannot get it to remove the date when the converted time passes midnight. [Code] The string was not recognized as a valid DateTime. There is an unknown word starting at index 18.

How to Do this Operation with Code VBnet 2005?
In Microsoft Access I use: Hours(time) minute(time) function to get current time hour and minute. I then use loop to add to the minutes until it ends in a 5 or 0 to round it up to the next 5 minutes. e.g. 13:43 rounded up to 13:45 I use IF statement to make sure the minute does not exceed 60 to start the hour. I want to use that time to add hours or minutes to easier e.g. add 15minutes, add 1 hour ect.

In some text boxes I enter times like "08:00 16:00" then another textbox next to it will display 8 hours then a label at the bottom calculates the total overall hours. There are a total of 7 textboxes for times entered and like the example above and another 7 for the calculation of that days hours worked. My problem is when I enter "08:00 16:30" the total hours in that text box would be displayed "8.5 hours". I need to tweak this so it is displayed 8 1/2 hours. My second issue is that the label that displays the overall hours only calculates if I enter times like "08:00 16:00" if i entered "08:00 16:30" it would not calculate
Here is my code:
vb

txtTuesdaysTimeKeeping.TextChanged, txtWednesdaysTimeKeeping.TextChanged, txtThursdaysTimeKeeping.TextChanged, txtFridayTimeKeeping.TextChanged, _

View 1 RepliesSearching about kernel32.dll and battery functions in it, I came across some interesting
Public BatteryLifeTime As System.UInt32
The full declaration is:
Private Declare Auto Function GetSystemPowerStatus Lib "kernel32.dll" ( _
ByRef lpSystemPowerStatus As SYSTEM_POWER_STATUS) _
As Integer
Private Structure SYSTEM_POWER_STATUS
Public BatteryLifeTime As System.UInt32
What I don't understand is, what measurement do the "BatteryLifeTime As System.UInt32" is in? I mean, is the Battery life Time in seconds or hours.. Or something else, so how can I convert it to something I can use..

I have no idea how this is done. Can anyone point me to a tutorial or give a quick explanation. Sample code would be great as well.

I was just thinking what is the best way to make daily update system? I have a perfectly work system that checks for updates and downloads the latest files and all that. But one problem the user has to click check for updates button first. I think the real question is how can i add 3 hours to let say 10:00. I also think using the 24 hour system would probably be easier.

Above is the code I am using and I get null reference was unhandled error. What I want to do is to find first the element with id old_sl which is a <span> then I want to get all the elements into that span with tag <option>.
What would I need to add to my if statement to grab the inner text of that span id and place it into a Label?
