I have an ASP.NET form(using C#) with several text boxes and when the user places a date in the first textbox and clicks a button, I would like to populate the remaining textboxes with various dates subtracted from the date in the first textbox - any suggestions? I do know that the datetime class has a subtract method, but I'm not sure how to use it. Incidentally I'm using ASP.NET 2005 and obviously a beginner - please help!

Thanks,
Mike

Mike,

Here is some code that may help. Before it gets lost, I would like to pass a value to a function from a label to a function, but can't find the syntax. If you happen to know how to do that, I would appreciate the help.

Your code:


string strDate;

// Calculating the tomorrow's date (adding days to the current date.)
DateTime tomorrow = DateTime.Today.AddDays( 1 );
strDate = tomorrow.ToString("dd / MM / yy");

// Calculating the yesterday's date (substracting days from current date.)
DateTime yesterday = DateTime.Today.AddDays( -1 );
strDate = yesterday.ToString("dd / MM / yy");

// Calculating the time after 15 minute (adding minutes to the current
time.)
// Format : 09 / 08 / 06, 12 : 60
DateTime later = DateTime.Now.AddMinutes( 15 );
strDate = later.ToString("dd / MM / yy, hh : mm ");


// Calculating the time after 1 hour (adding minutes to the current
time.)
// Format : 09 / 08 / 06, 12 : 60
DateTime later = DateTime.Now.AddMinutes( 60 );
strDate = later.ToString("dd / MM / yy, hh : mm ");


// Calculating the time before 1 hour (adding minutes to the current
time.)
// Format : 09 / 08 / 06, 12 : 60
DateTime later = DateTime.Now.AddMinutes( -60 );
strDate = later.ToString("dd / MM / yy, hh : mm ");

Why the formatting of "MM" is different from "yy" or "dd"? Anyone can tell me the reason?

Thanks,

The main reason for that is because DateTime dataType can have time format also, wich means HH:mm:ss (Hours:minutes:seconds). Therefore, Months (MM) must have a different format than minutes (mm). Days and years are good in lowercase.
