AddPrinter in VB
Finally, after I try many options, I would like to use AddPrinter API to create a printer in vb, but, this function return 0.
When I launch with :
? CreatePrinter ("\\KIWI", "HP Laserjet 4L"), there is nothing. This function return false.
My server name is \\KIWI and my printer is HP Laserjet 4L.
What's wrong ? Is it possible to send a stirng and not pointer ?
Thanks for your help.
The Api is :
Private Declare Function AddPrinter Lib "winspool.drv" Alias "AddPrinterA" (ByVal pName As String, ByVal Level As Long, pPrinter As PRINTER_INFO_2) As Long
The PRINTER_INFO_2 :
Private Type PRINTER_INFO_2
pServerName As String
pPrinterName As String
pShareName As String
pPortName As String
pDriverName As String
pComment As String
pLocation As String
pDevMode As Integer
pSepFile As String
pPrintProcessor As String
pDatatype As String
pParameters As String
pSecurityDescriptor As Integer
Attributes As Long
Priority As Long
DefaultPriority As Long
StartTime As Long
UntilTime As Long
Status As Long
cJobs As Long
AveragePPM As Long
End Type
The code is :
'Ajoute une imprimante à l'ordinateur
Public Function CreatePrinter(strServer As String, strPrinter As String) As Boolean
Dim hPrinter As Long
Dim pi2 As PRINTER_INFO_2
Dim bBuffer(1000) As Byte

Just a small info! Put that Api declaration before that type declaration.

Sorry for the delay,
I've finished recently the module and I can now create, remove or change any settings of printers.
I was use the WScript.Network object to manipulate the printer.
Thanks again.

Thanks again.
Curious as to why I was graded with a 'B' on this?
Seems like a two-line solution that replaces one-hundred+ lines of code and also provides you the object by which to manipulate your printer would warrant an 'A'.

It appears that more lines of code means better code/more effort.
Ridiculous!!
