VBA and Putty's pscp.exe when username includes # characters - vba

Question

I have some VBA code which is using Putty's pscp.exe file for logging on Unix server. I am using Windows 7.
The problem is that the username includes a # character. I am not able to login if I use the following VBA code.
So, how should I replace Username = "user#example.xxx" to be able to login?
Dim Host As String
Host = "grid1.example.xxx"
Dim Username As String
Username = "user#example.xxx"
Dim Password As String
Password = "Password2012"
Dim Command As String
Command = "pscp.exe -sftp -l " & Username & " -pw " & Password
Shell Command, vbNormalFocus

Answer 1

Worked for me as below:
Dim Host
Host = "grid1.example.xxx"
Dim Username
Username = "username#host"
Dim Password
Password = "Password"
Dim Command
Command = "pscp.exe -l " & Username & " -pw " & Password & " cmd.txt username#host:cmd.txt"
Set oShell = CreateObject ("WScript.Shell")
oShell.run "cmd /k " & Command

Sorry, don't know how to format correctly in the comments section, so posting here. Try to run it in a .bat file instead.
I do think, however, the username should not include the hostname, and rather get concatenated in the target %Hostname%.
#echo off
set Username="username#hostname"
set Password=Password
set Hostname=hostname
rem or maybe like this
rem set Username=username
rem set Hostname=username#hostname
pscp32.exe -sftp -l %Username% -pw %Password% cmd.txt %Hostname%:cmd.txt
if errorlevel 2 goto Err2
if errorlevel 1 goto Err1
echo success!
goto :EOF
:Err2
echo error 2
goto :EOF
:Err1
echo error 1
goto :EOF
