| also das ist die form auf der angezeigt werden soll, wie der name, der status, der ping des computers mit der ip-nummer, die in IPNummer drin steht. was noch nicht funktioniert ist das der name angezeigt wird.
hier der scoure code:
Private Sub Aktualisieren_Click()
Dim strComputername As String
Dim ECHO As ICMP_ECHO_REPLY
Dim pos As Integer
'Die Ping-Funktion aufrufen:
Call Ping(Trim$(Form1.IPNummer), ECHO)
'Ergebnisse anzeigen
Status2.Caption = GetStatusCode(ECHO.Status)
Zeit2.Caption = ECHO.RoundTripTime & " ms"
Datasize2.Caption = ECHO.Datasize & " bytes"
If ECHO.Status = 0 Then
LEDStatus.Picture = LoadPicture("LEDgrün2.bmp")
Else
LEDStatus.Picture = LoadPicture("LEDrot2.bmp")
End If
Form2.Caption = "Infos über PC mit der IP: " & Form1.IPNummer
IP2.Caption = Form1.IPNummer
strComputername = Form1.IPNummer
End Sub
Private Sub Form_Load()
Dim ECHO As ICMP_ECHO_REPLY
Dim pos As Integer
'Die Ping-Funktion aufrufen:
Call Ping(Trim$(Form1.IPNummer), ECHO)
'Ergebnisse anzeigen
Status2.Caption = GetStatusCode(ECHO.Status)
Zeit2.Caption = ECHO.RoundTripTime & " ms"
Datasize2.Caption = ECHO.Datasize & " bytes"
If ECHO.Status = 0 Then
LEDStatus.Picture = LoadPicture("LEDgrün2.bmp")
Else
LEDStatus.Picture = LoadPicture("LEDrot2.bmp")
End If
Form2.Caption = "Infos über PC mit der IP: " & Form1.IPNummer
IP2.Caption = Form1.IPNummer
End Sub
und dann habe ich noch ein modulmit dem ich den ping und den status bekomme:
