Convert date to string format

[ljs235]

I am logging user actions throughout my program using datetime in the format hh:mm:ss:ff. I would like to calculate the difference between two times. Here is what I'm using for code:

 

Dim Time As Date

Time = DateTime.Now

Dim TaskTime As TimeSpan = Time.Subtract(AddMainBTime)

LogWriter.WriteLine("*TaskTime " & (TaskTime.ToString))

 

This works great, but I cannot figure out how to format the TaskTime to hh:mm:ss:ff. Right now, it writes to the file as hh:mm:ss.fffffff. When I try the following, I get the following error: 'Public Overrides Overloads Function ToString() As String' has no parameters and its return type cannot be indexed.

 

LogWriter.WriteLine("*TaskTime " & (TaskTime.ToString("hh:mm:ss:ff")))

 

Any ideas on how I can format my TimeSpan value? Thanks. :)

You can break a string down using LEFT and RIGHT facilities, i cant remember the exact context for this, but i think this should give u an idea.

 

MsgBox(Microsoft.VisualBasic.Left("hello", 3))

MsgBox(Microsoft.VisualBasic.Right("hello", 3))

 

SHOULD return the value "hel" and "llo", you can use this to break the dates down, and remove the annoying 20 out of 2003, or pretty much anything else - obviously you can also embed them into each other.

Well if you take the 20 out, they might think 1903 :p

Thanks so much for your help. Here is how I resolved the situation:

 

LogWriter.WriteLine("*TaskTime " & (Microsoft.VisualBasic.Left(TaskTime.ToString, 11)))

 

Thank you!!!

You should stay away from Left and Right, in general. The string object supports a Substring method which does everything you need. Try this instead:

LogWriter.WriteLine("*TaskTime " & TaskTime.ToString().Substring(11))
