Tokenizing

[Craig Buchanan]

I'm trying to extract the key/value pairs string like this:

[Status]
CurrTime = 1200
LastPlayQUpdate = 400
CurrVolume = -10
[End Status]

My first instinct is to use a regular expression to match values before and
after the '=', but there probably is a more efficient method.

Can anyone suggest a better approach?

Thanks,

Craig Buchanan

Dim strPairs() As String = Split(line, "=")

You could load the text file (I guess i am assuming this is where the
data is from) line by line and extract the pairs.

Hello Craig,

This is an INI file. Use DllImport ('Declare' keyword in VB) to import
GetPrivateProfileString from Kernel32.dll.
In fact there are several GetPrivateProfile* functions.

Craig,

As alternative from Charlie,

You can just use the string.lastindex of method (although in this sampe the
standard indexoff method goes as well to) to get the starting point for a
string.substring.)

Alternatively you can use as well the Find and the Mid

I hope this helps,
