Free source code VB - Cara Set Printer

Berikut adalah skrip vb / source code vb untuk menampilkan printer pada windows.

Sebelumnya buat modul pada visual basic kemudian masukan skrip dibawah ini :
Public Const MAX_COMPUTERNAME_LENGTH As Long = 31
Public Declare Function GetComputerName Lib "kernel32" Alias "GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" (ByVal HKEY As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long
Declare Function RegCloseKey Lib "advapi32.dll" (ByVal HKEY As Long) As Long
Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal HKEY As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal HKEY As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, ByVal lpData As String, lpcbData As Long) As Long
Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal HKEY As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long

Const REG_SZ = 1&
Const KEY_QUERY_VALUE = &H1&
Const KEY_SET_VALUE = &H2&
Const KEY_CREATE_SUB_KEY = &H4&
Const KEY_ENUMERATE_SUB_KEYS = &H8&
Const KEY_NOTIFY = &H10&
Const READ_CONTROL = &H20000
Const STANDARD_RIGHTS_READ = READ_CONTROL
Const STANDARD_RIGHTS_WRITE = READ_CONTROL
Const KEY_READ = STANDARD_RIGHTS_READ Or KEY_QUERY_VALUE Or KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY
Const KEY_WRITE = STANDARD_RIGHTS_WRITE Or KEY_SET_VALUE Or KEY_CREATE_SUB_KEY
Dim HKEY As Long, MainKeyHandle As Long
Dim rtn As Long, lBuffer As Long, sBuffer As String
Dim lBufferSize As Long

Function GetStringValue(SubKey As String, Entry As String)
Call ParseKey(SubKey, MainKeyHandle)
If MainKeyHandle Then
rtn = RegOpenKeyEx(MainKeyHandle, SubKey, 0, KEY_READ, HKEY)
If rtn = ERROR_SUCCESS Then
sBuffer = Space(255)
lBufferSize = Len(sBuffer)
rtn = RegQueryValueEx(HKEY, Entry, 0, REG_SZ, sBuffer, lBufferSize)
If rtn = ERROR_SUCCESS Then
rtn = RegCloseKey(HKEY)
sBuffer = Trim(sBuffer)
GetStringValue = Left(sBuffer, Len(sBuffer) - 1)
End If
End If
End If
End Function

Private Sub ParseKey(Keyname As String, Keyhandle As Long)
rtn = InStr(Keyname, "\")
If rtn = 0 Then
Keyhandle = &H80000001
Keyname = ""
Else
Keyhandle = &H80000001
Keyname = Right(Keyname, Len(Keyname) - rtn)
End If
End Sub
Function CreateKey(SubKey As String)
Call ParseKey(SubKey, MainKeyHandle)
If MainKeyHandle Then
rtn = RegCreateKey(MainKeyHandle, SubKey, HKEY)
If rtn = ERROR_SUCCESS Then
rtn = RegCloseKey(HKEY)
End If
End If
End Function
Function SetStringValue(SubKey As String, Entry As String, Value As String)
Call ParseKey(SubKey, MainKeyHandle)
If MainKeyHandle Then
rtn = RegOpenKeyEx(MainKeyHandle, SubKey, 0, KEY_WRITE, HKEY)
rtn = RegSetValueEx(HKEY, Entry, 0, REG_SZ, ByVal Value, Len(Value))
rtn = RegCloseKey(HKEY)
End If
End Function

Kemudian buat sebuah form baru dan 1 buah command kemudian masukan skrip viasl basic dibawah ini :

Private Declare Function OpenPrinter Lib "winspool.drv" Alias "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As Long, pDefault As Any) As Long
Private Declare Function ClosePrinter Lib "winspool.drv" (ByVal hPrinter As Long) As Long
Private Declare Function PrinterProperties Lib "winspool.drv" (ByVal hwnd As Long, ByVal hPrinter As Long) As Long

Private Sub Command1_Click()
SetStringValue "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows", "Device", "Lord,winspool,Ne00:"
End Sub
