Hi,

It is easy.... assume that you are calculate the character are from ascii 1 to ascii 255.

Declare one integer array of 255 slots:

then read byte by byte, convert to ascii code and put it into the ascii code slot. Ex:

freq(asc(myChar)) +=1

Loop all then way until finish and then check the result.

hello friends... may be my doubts seems to be stupid... but i really want to know...

Imports system
Imports System.Net.DNS

Private Function GetIPAddress() As String
Dim oAddr As System.Net.IPAddress
Dim sAddr As String
With system.Net.DNS.GetHostByName(system.Net.DNS.GetHostName())
oAddr = New System.Net.IPAddress(.AddressList(0).Address)
sAddr = oAddr.ToString
End With
GetIPAddress = sAddr
End Function

Private Function GetName() as string
Dim shostname As String
shostname = system.Net.DNS.GetHostName
return shostname
End Function

to list the shared folder, just Dir("\\" & myHostTarget ) and filter with folder attribute.
