If your string is always in that format, an easy way would be:

strA = Left(FullString, InStrRev(FullString, ".") - 1)
strB = Left(strA, InStrRev(strA, ".") - 1)
ContainerStr = Mid(strB, InStrRev(strB, ".")  + 1)

You could fool around to use just one variable, but this is probably easier to see.

Can you explain it a little more because I can't follow completly. Are you're string always the same (with a changin name of the containernumber) ?

txt = "Main.store.box1.container1.aiibox.value = 100"
pos = InStr(1, txt, "container")
txt = Right(txt, Len(txt) - (InStr(1, txt, "container")) + 1)
txt = Left(txt, InStr(1, txt, ".") - 1)

Another way to do this is using the Split() function, which will break apart a string into array elements, using a delimiter you specify.  In this case you can break apart at the periods like this:

strTemp = "Main.store.box1.container1.aiibox.value = 100"
strFields = Split(strTemp, ".")
Wscript.Echo strFields(3)

Open in new window

Just keep in mind that the resulting array is zero based, so the first elemnet will be strFields(0).
