任何人都可以帮助我将其转换为自动,或者至少告诉我如何在autoit中执行此操作?
Private Const DC_PAPERNAMES = 16
Private Declare Function DeviceCapabilities Lib "winspool.drv" _
Alias "DeviceCapabilitiesW" ( _
ByVal lpDeviceName As Long, _
ByVal lpPort As Long, _
ByVal iIndex As Long, _
ByVal lpOutput As Long, _
ByVal lpDevMode As Long) As Long
Private Sub Form_Load()
Dim P As Printer
For Each P In Printers
lstPrinters.AddItem P.DeviceName
Next
End Sub
Private Sub lstPrinters_Click()
Dim P As Printer
Dim lngPapers As Long
Dim strPaperNames As String
Dim lngPaper As Long
Dim strPaperName As String
Dim lngActualLength As Long
Set P = Printers(lstPrinters.ListIndex)
lngPapers = DeviceCapabilities(StrPtr(P.DeviceName), _
StrPtr(P.Port), _
DC_PAPERNAMES, _
0, _
0)
strPaperNames = String$(lngPapers * 64, 0)
lngPapers = DeviceCapabilities(StrPtr(P.DeviceName), _
StrPtr(P.Port), _
DC_PAPERNAMES, _
StrPtr(strPaperNames), _
0)
lstPapers.Clear
For lngPaper = 0 To lngPapers - 1
strPaperName = Mid$(strPaperNames, 64 * lngPaper + 1, 64)
lngActualLength = InStr(strPaperName, vbNullChar) - 1
If lngActualLength > 1 Then strPaperName = Left$(strPaperName, lngActualLength)
lstPapers.AddItem strPaperName
Next
End Sub

这是一个线程,有人试图做同样的事情:http://www.autoitscript.com/forum/topic/25857-need-a-help-from-the-pros-on-making-api-call/
还有一个指南可以帮助您编写Windows API调用:http://www.autoitscript.com/forum/topic/7072-dllcall/它主要处理找到正确的类型转换,这是唯一的难点。
