Okay, those doublets, doubles, pairs of characters are already in hex notation. To retrieve their values, put &h in front of them...

Dim Value As String
Value = "FF"
debug.print CByte("&h" & Value)
debug.Print CInt("&h" & Value & Value) 'actually returns -1 so use clng
debug.Print CLng("&h" & Value & Value & Value)
debug.Print CLng("&h" & Value & Value & Value & Value) 'returns -1 so use cdbl

Good Luck

hi there, thank you for your reply. i found another way that's more simple. because it's unnecessary to be Hex number, decimal is just fine. so this is my solution :

Dim s As String ' e.g 05 04 F4 ...
Dim i As Integer = Convert.ToInt32(Trim(s),16)

Best regards!

Well for future reference there real, you are in the wrong forum. You need to be in the vb.net forum...
