Do not understand this function stand for???

i'm newbie in VB6. Can somebody explain what is this function for? I get this function from internet and for learning knowledge. Thank you.

VB Code:

Public Function BreakStr(ByVal Text As String, ByVal Char As String, ByVal Where As Integer) As String 'Very useful function
Dim i As Long, temp As String, m As Long
 
For i = 1 To Len(Text)
    temp = Mid(Text, i, Len(Char))
        If temp = Char Then
            m = i
            If Where = 1 Then 'before
                    temp = Mid(Text, 1, m - 1)
                    BreakStr = temp
                    Exit Function
            Else
                    temp = Mid(Text, m + Len(Char), Len(Text))
                    BreakStr = temp
                    Exit Function
            End If
        End If
Next
If Where = 1 Then BreakStr = Text
End Function

hav u tried to test it... you can also make your own function

im sorry i cant understand this code bcoz it seems have errors [somebody correct me if im wrong]

the condition if WHERE = 1 - i think this will produce syntax error

As the name suggests the function is used to break string at a specified character position.

for example, if you write

VB Code:

Debug.Print BreakStr("this is a test", "s", 0)

Then the result will be is a test. What the function will do is that it will take all the characters after the first s and print return them. Now if you write anyother value apart from 0 then it will take all the characters that are to the left of the first occurence of the character.

This can be achieved by using the built-in vb functions like Mid, Instr & Left. There is no need to write the function.

temp = Mid(Text, i, Len(Char))
If temp = Char Then
m = i

Why we need to check the length of character?

it's not checking the length, it's returning a string the same length as Char (in case Char is longer than one - it's a bit misnamed)

This function should be using Split, and can be done a lot easier with it

I added vbcode tags to your post to make it easier to read.

Ok..thank you friend.
Do you have any example to show how this code works?
Example: string => "I am a boy"

How it runs?
Any idea. Shariing is caring. ;)

I would suggest, try to execute it yourself. It wil be easier to understand when you debug through the function.

Between, is it this same like the origin example??
if no then what is the difference? Thank you.

<vb code>
Public Function BreakStrEx(ByVal Text As String, ByVal Char As String, ByVal Where As Integer) As String
Dim i As Long, temp As String, m As Long

For i = Len(Text) To 1 Step -1
temp = Mid(Text, i, Len(Char))
If temp = Char Then
m = i
If Where = 1 Then 'before
temp = Mid(Text, 1, m - Len(Char))
BreakStrEx = temp
Exit Function
Else
temp = Mid(Text, m + Len(Char), Len(Text))
BreakStrEx = temp
Exit Function
End If
End If
Next
If Where = 0 Then BreakStrEx = Text
End Function
<vb code>

You almost got the vbcode tags right, the one at the end should be [/vbcode]
