Hi,

Some one please guide me how to automate putty using vba. I am able to invoke putty.exe using Shell command, but not able to enter the user name and password. Tried Sendkeys for entering username, but that is not working.

PuttyWindow = Shell("D:\putty.exe -telnet servername", vbNormalFocus)
AppActivate PuttyWindow, True

Application.Wait (Now + TimeValue("0:00:02"))

SendKeys "username", True
SendKeys "{ENTER}", True


Thanks in Advance
Jose

Here is the full code.
Dim PuttyWindow
PuttyWindow = Shell("C:\Program Files\Microsoft Application Virtualization Client\sfttray.exe /launch PuTTY username @server ", vbNormalFocus)
AppActivate PuttyWindow, True
Application.Wait (Now + TimeValue("0:00:05"))
SendKeys "Password"
SendKeys "{ENTER}"

This:

VBA Code: 
#If VBA7 Then
Public Function GetWindowHandle(hInstance As Long) As Long
#Else
Public Function GetWindowHandle(hInstance As Long) As Long
#End If

needs to be this:

VBA Code: 
#If VBA7 Then
Public Function GetWindowHandle(hInstance As LongPtr) As LongPtr
#Else
Public Function GetWindowHandle(hInstance As Long) As Long
#End If

But now getting ByRef argument type mismatch for idProc
VBA Code: 
Option Explicit

Private Const ConsoleClassName As String = "ConsoleWindowClass"
Private Const PuTTYClassName As String = "PuTTY"

Private Const WM_CHAR As Long = &H102
Private Const WM_KEYDOWN As Long = &H100

Issue resolved after correcting
Dim idProc As LongPtr

VBA Code: 
#End If
    Dim idProc As LongPtr
   
    ' Get PID for this HWnd
    GetWindowThreadProcessId hwnd, idProc

VBA Code: 
#If VBA7 Then
Public Function GetWindowHandle(hInstance As Long) As LongPtr
#Else
Public Function GetWindowHandle(hInstance As Long) As Long
#End If
I think the above is correct, however I used a confusing name for hInstance, because it's actually a process id (always a Long), not a handle of any kind.

The error is in ProcIDFromWnd, where a pointer to idProc should be passed by value to GetWindowThreadProcessId, as shown here:
VBA Code: 
#If VBA7 Then
Private Function ProcIDFromWnd(ByVal hwnd As LongPtr) As Long
#Else
Private Function ProcIDFromWnd(ByVal hwnd As Long) As Long
#End If
    Dim idProc As Long

    ' Get PID for this HWnd
    GetWindowThreadProcessId hwnd, VarPtr(idProc)
  
    ' Return PID
    ProcIDFromWnd = idProc
End Function

Based on post #11, Putty automation using excel vba, here is the complete code with the corrections.

Test routine in a standard module (eg. Module1):
VBA Code: 
Option Explicit

Public Sub test()

    Dim PuttyPID As Double
    #If VBA7 Then
    Dim PuttyHwnd As LongPtr
    #Else
    Dim PuttyHwnd As Long
    #End If
    Dim serverName As String, username As String, password As String
 
    serverName = "xxx.yyy"
    username = "xxxx"
    password = "xxxx"
 
    PuttyPID = Shell("C:\Program Files\PuTTY\putty.exe -telnet  " & serverName, vbNormalFocus)   'CHANGE PATH TO .EXE
 
    'Get window handle of the PuTTY Telnet command window

    PuttyHwnd = GetWindowHandle(CLng(PuttyPID))
 
    If PuttyHwnd <> 0 Then
     
        SendChars PuttyHwnd, username & vbCr
        Application.Wait DateAdd("s", 1, Now)
 
        SendChars PuttyHwnd, password & vbCr
        Application.Wait DateAdd("s", 1, Now)
 
        SendChars PuttyHwnd, "DIR" & vbCr  'DIR command
 
    End If
 
End Sub
API declarations and supporting functions in a standard module (e.g. Module2):
VBA Code: 
Option Explicit

Private Const ConsoleClassName As String = "ConsoleWindowClass"
Private Const PuTTYClassName As String = "PuTTY"

Private Const WM_CHAR As Long = &H102
Private Const WM_KEYDOWN As Long = &H100
Private Const GW_HWNDNEXT = 2
