I am using this line of code on form load event it is working very fine but i have to problems
1. It replaces the form name and display the date and time but i want to keep both date and time and forms caption separated by some space.
2. When form loads it load the current date and time but the time does not change it should run.
What should i do please please help me code is as follows
Me.Text = Date.Now.ToLongDateString & " - " & TimeOfDay
The Now() function in VB.NET returns date and time which is different from the system time that I see on the right-bottom on the notification bar. It is 15 hours slower than the system time. Has anyone ever met this problem? I'm using .NET 2.0.
View 2 RepliesI am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.
I am trying to change the PC's System Date/Time using the following code. Everything works but the Hour. The Hour seems to change to 9:00 AM no matter what value st.hour is set to.
I have also tried:

Public Shared Function SetSystemTime(ByRef theDateTime As SYSTEMTIME) As Boolean
End Function

How do you set the system Time/Date programatically?

View 1 RepliesI am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

View 1 Replieswhy did they make this so hard to do. Does anyone have any clear cut, basic 3-4 lines of code that can tell me how to add 2 time variables together to create a 3rd variable? I tried this but on Time2 I get Value of type 'Date' cannot be converted to 'System.TimeSpan'.

I have a application which gets info from an external feed where dates are in the format ddMMM. I'm trying to turn them into full date format so I was using DateTime.ParseExact. Which was correctly working out whether it should be 2011 or 2012 . But it is erroring when trying to parse 29FEB (which should be 29 Feb 2012. I can guess why its erroring. But if that correct behaviour is this documented and is there a better alternative? [code]

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?

View 6 RepliesI'm building an application in which a certain CSV schedule is read and searched for time and date values.
I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.
How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?
The contents of the CSV file will look something like this:
;Schedulename;text;text;31-10-2011;text;text;6-11-2011;text;;;text
Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.
Dim CSVReadline As New System.IO.StreamReader(schedule.csv")
Cellcheck = CSVReadline.ReadLine()
String = Cellcheck.Split(";")
For i = 0 to 10
Scheduledate = String(i) ............ etc.
