help to capture a value in line

[Rosemine]

Hello, how can i capture the value of left in the line below using string function:

left position is left:215px

i must capture the value 215.

Thanks...

Just get the index of the colon and the index of px, and get whats inbetween.

Dim colonIndex as Integer
Dim capLength as Integer
Dim capturedString as String
Dim dataString as String = "left position is left:215px"
colonIndex = dataString.IndexOf(":")
'Gets the length of the string inbetween the colon and px
capLength = dataString.IndexOf("px") - colonIndex
capturedString = dataString.Substring(colonIndex + 1, capLength)

Something along those lines

Unless the format of your string is always the same (i.e the number always comes after the 1st ":" and it always has 3 digits...), in which case you can use string manipulation as shown by Cellus, you'd better have a look at regular expressions.
