I wish to display a greeting to the user when they start an application. It's very simple "Good Morning John" or "Good Afternoon John" or "Good Evening John" depending on the time of day. How do create a time variable where it's based on 24 and not 12?
View 3 RepliesI 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.

View 5 RepliesI am working on code for a countdown timer, where 2 labels (Minutes label = label6 and Seconds label = label7). I have tried for a long time to try and get this to work, and it has to be "Hours:Minute" format. I will add below the awful start I have made
If Label7.Text = "1" Then
Label6.Text = (Label6.Text) - Val(1)
ElseIf Label7.Text = "1" Then
Label7.Text = "59"

There is lots of bugs, such as the last minute is cut out, and it is just buggy, the user must be able to select a time/duration for the timer to work, and also this must be able to change every time the time reaches 00:00.

View 4 RepliesI 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?
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

View 2 RepliesI have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.

View 1 RepliesI am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime.

Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?
