Testing a valid IP address? ( SOLVED! )

[JC]

Uwe,

One question about the tool getip: It can get the information of another machine, running into my machine?

[anserkk]

Dear JC,

When I try

C:\>ping PC1

PC1 responds back with the IP address.

From the command prompt everything is fine.

My network contains a DOMAIN


Dear Uwe,

Thankyou for the suggestion. I have not tried the utility which you have specified. I prefer to get the results without installing any extra utility. If my app runs in a single PC then I can think of installing the utility, but what if the app is supposed to work on atleast 10 to 15 PC's in the network. Every machine needs the extra utility to be installed to get the result which I don't prefer


Regards

Anser

Anser,

I assume a ping into another machine on your network, by the name it, responds as it should?

Sorry for my insistence, but we need to test all of situations to resolve this problem...

Dear JC,

I assume a ping into another machine on your network, by the name it, responds as it should?

Yes Ping is reponding back by name as well as IP

Hello,

I found a V-Basic-source in german-forum for PING inside a application ( I don't know, if it is usefull, otherwise i can delete it again ).
Maybe it is possible to translate it to FWH ?
i translated the german-source to english

< Sensapi.dll > is used for API-function

Code: Select all  Expand view


// API
Private Declare Function IsDestinationReachable Lib "Sensapi.dll" _
Alias "IsDestinationReachableA" (ByVal lpszDestination As String, _
                                     lpQOCInfo As QOCINFO) As Long

Private Type QOCINFO
    dwSize As Long
    dwFlags As Long
    dwInSpeed As Long
    dwOutSpeed As Long
End Type

// PING to Server ( Returns reaction-time )
Public Function Ping(ByVal sHost As String) As Single
    Dim QI As QOCINFO
    Dim vTime As Single
 
    QI.dwSize = Len(QI)
    vTime = Timer
    If IsDestinationReachable(sHost, QI) = 1 Then
        Ping = Timer - vTime
      Else
        Ping = -1
    End If
End Function

'How to use :
'use in local LAN for sHost computer-name :
Sub a()
    Dim nTime As Single
   
    nTime = Ping("\\computername")
    If nTime <> -1 Then
        MsgBox "computer not reachable : Pingtime : " & CStr(nTime) & " Seconds"
      Else
        MsgBox "computer not reachable !"
    End If
End Sub

'Testing reaction-time of a Webserver use IP-Adress of Server or the Hostname :
Sub b()
    Dim nTime As Single

    nTime = Ping("www.myAdress.de")
    If nTime <> -1 Then
        MsgBox "Server not reachable : Pingtime : " & CStr(nTime) & " Seconds"
      Else
        MsgBox "Server not reachable !"
    End If
End Sub

// Or ...
Sub c()
    Dim nTime As Single
   
    nTime = Ping("217.160.105.148")
    If nTime <> -1 Then
        MsgBox "Server not reachable : Pingtime : " & CStr(nTime) & " Seconds"
      Else
        MsgBox "Server not reachable !"
    End If
End Sub

Uwe,

This function is wonderful! I think yes, it's possible translate to FWH language! Let's go to work!

Hello JC,
another version I found ( a bit different and shorter returns just .T. or .F. ) :

Code: Select all  Expand view


// API
Private Declare Function IsDestinationReachable Lib _
  "Sensapi.dll" Alias "IsDestinationReachableA" _
  (ByVal lpszDestination As String, _
  lpQOCInfo As QOCINFO) As Long

Private Type QOCINFO
  dwSize As Long
  dwFlags As Long
  dwInSpeed As Long
  dwOutSpeed As Long
End Type
// Ping returns .T. or .F.

Public Function Ping(ByVal IP As String) As Boolean
  Dim QuestStruct As QOCINFO
  Dim lReturn As Long

// Structure-Size
  QuestStruct.dwSize = Len(QuestStruct)

// Destination-test
  lReturn = IsDestinationReachable(IP, QuestStruct)
 
// using answer
  If lReturn = 1 Then
    // Answer .T.
    Ping = True
  Else
    // Answer .F.
    Ping = False
  End If
End Function

Rochinha,

Wonderful! Perfect function!
Maravilhoso! Função perfeita meu garoto!

Resolveu muitos dos problemas com teste de conexão aqui no nosso sistema! Valeu!

[Patrick Mast]

Hey Guys,

Sorry but I can not get this to work on my Wndows Vista computer. It compiles ok, but the exe just does not do anything. Do you have a running sample?

Patrick

Patrick,

Download at http://www.5volution.com/forum/pinga.zip

This version is tested on Vista Ultimate and Windows server 2003.
