[2005] Spliting a string

[steve_rm]

hello,

I have developed some code below to split a string.

In a string I get back from a database i have for example "13 Hours". I have to split this and put them into 2 different string variables. So it would separate 13 from hours.

Does anyone know of any better method to do this.

Many thanks,

'Split the estimated duration into value and periodically (dates) i.e. "4 Days" to "4" "Days"
Dim duration As String = Me.DsIncidentsControl.IncidentTask(0).EstimatedDuration
Dim strArray(2) As String 'Array with 2 element to hold the number and date
                strArray = duration.Split(" ") 'Split at the space
                Me.txtEstimatedDuration.Text = strArray(0) 'Assign the number value
                Me.cboDuration.Text = strArray(1) 'Assign the date

First off, don't define the array size. Let the Split() function do that.

Other than that, I don't know of a better way to split strings. That's what the Split function is for, and it's kinda hard to beat...

Thanks,

This is the update

Dim strArray() As String 'Array with 2 element to hold the number and date
                strArray = duration.Split(" ") 'Split at the space

well you really can't do this another way but you can change the code.

'Split the estimated duration into value and periodically (dates) i.e. "4 Days" to "4" "Days"
Dim duration As String = Me.DsIncidentsControl.IncidentTask(0).EstimatedDuration
'Dim strArray(1) As String 'Array with 2 element to hold the number and date // Arrays start at 0 so before with strArray(2) you were defining an array with 3 slots.
                'strArray = duration.Split(" ") 'Split at the space //we can just leave out this step but another way to do it is... Split(duration," ") 'because vb is so friendly :P.
                'dim strArray() as string = duration.Split(" ") ' another way of splitting into an array.
                Me.txtEstimatedDuration.Text = duration.Split(" ")(0) 'Assign the number value //instead of defining and then accessing the array we can just split and access right away.
                Me.cboDuration.Text = duration.Split(" ")(1) 'Assign the date

steve,

I would also say that in your post 3 it's not entirely correct. You split by a character so you should have:

Dim strArray() As String = duration.Split(" "c) 'Split at the chr space

Or

Dim strArray() As String = duration.Split(CChar(" ")) 'Split at the space

[timeshifter]

That's understood by VB.

Personally, I'm kinda stuck on the VB6 method of doing it:

Dim strArray() As String = Split(duration, " ")

Hello

What is the difference between:

Me.txtEstimatedDuration.Text = duration.Split(" "c)(0) 
and 
                Me.txtEstimatedDuration.Text = duration.Split(" ")(0)

I left out the c in the second one. However both worked fine. Just wondering what the difference is.

If you turn Option Strict On then you will see why the c is put there.

Thanks Kimmy4,
