[2005] Spliting a string

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,

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(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

vb Code:

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.

VB 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:

vb Code:

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

Or

vb Code:

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

That's understood by VB.

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

vb Code:

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

Hello

What is the difference between:

vb Code:

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,
