dates

 

is this a good way to compare dates?

chk = (dt.AddDays(30).ToString < Date.Now.ToString)

 

i hope its comparing the dates and not the string length...as i think.

but the final result is ok..(i guess)

 

the dt date is a date which i took out from a file.

im trying to make a time evaluation...

You don't need to convert to strings to compare dates - just compare the dates:

chk = (dt.AddDays(30) < Date.Now)

i've tried that ....and it didnt work. but somehow now it works...maybe it was someting with my syntax which i havent noticed.

thanks!!!!

 

btw...when i should use the "timespan" thing??

 

read about it in msdn...but still cant figure it out. :confused: :confused:

You would use a timespan if you need to keep track of an arbitrary range of time (like the difference between two dates)

       Dim ts As TimeSpan
       ts = dt.AddDays(30).Subtract(Date.Now)

It looks like you might be setting up a 30-day demo of your software. If so you might also consider using a Julian date to eliminate any international date format problems and save a value rather than a date using CInt(Now().ToOADate). Then just subtract the current day value from the installation value.
