我想用更改打印机设置的方法可以解决这个问题。下面有一段较长的代码,是用来更改打印机设置的。试试:新建一个工程,在其中加入command1,再添加一个模块。 1、在模块中加入以下代码。 Option Explicit Public Enum PrinterOrientationConstants OrientPortrait = 1 OrientLandscape = 2 End EnumPrivate Type DEVMODE dmDeviceName As String * 32 dmSpecVersion As Integer dmDriverVersion As Integer dmSize As Integer dmDriverExtra As Integer dmFields As Long dmOrientation As Integer dmPaperSize As Integer dmPaperLength As Integer dmPaperWidth As Integer dmScale As Integer dmCopies As Integer dmDefaultSource As Integer dmPrintQuality As Integer dmColor As Integer dmDuplex As Integer dmYResolution As Integer dmTTOption As Integer dmCollate As Integer dmFormName As String * 32 dmUnusedPadding As Integer dmBitsPerPel As Integer dmPelsWidth As Long dmPelsHeight As Long dmDisplayFlags As Long dmDisplayFrequency As Long End TypePrivate Type PRINTER_DEFAULTS pDataType As String pDevMode As Long DesiredAccess As Long End TypePrivate Type PRINTER_INFO_2 pServerName As Long pPrinterName As Long pShareName As Long pPortName As Long pDriverName As Long pComment As Long pLocation As Long pDevMode As Long pSepFile As Long pPrintProcessor As Long pDataType As Long pParameters As Long pSecurityDescriptor As Long 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 TypePublic Const DMPAPER_A5 = 11 Public Const DM_IN_BUFFER As Long = 8 Public Const DM_OUT_BUFFER As Long = 2 Public Const DM_ORIENTATION As Long = &H1 Public Const DM_PAPERSIZE = &H2&Public Const PRINTER_ACCESS_ADMINISTER As Long = &H4 Public Const PRINTER_ACCESS_USE As Long = &H8 Public Const STANDARD_RIGHTS_REQUIRED As Long = &HF0000 Public Const PRINTER_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED Or _ PRINTER_ACCESS_ADMINISTER Or PRINTER_ACCESS_USE)Public Declare Sub CopyMemory Lib "kernel32" Alias _ "RtlMoveMemory" _ (hpvDest As Any, hpvSource As Any, ByVal _ cbCopy As Long)Public Declare Function OpenPrinter Lib "winspool.drv" Alias _ "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As _ Long, pDefault As Any) As LongPublic Declare Function ClosePrinter Lib "winspool.drv" _ (ByVal hPrinter As Long) As LongPublic Declare Function DocumentProperties Lib "winspool.drv" Alias "DocumentPropertiesA" (ByVal hWnd As Long, ByVal hPrinter As Long, ByVal pDeviceName As String, pDevModeOutput_ As Any, pDevModeInput As Any, ByVal fMode As Long) As LongPrivate Declare Function GetPrinter Lib "winspool.drv" Alias "GetPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, pPrinter As Any, ByVal cbBuf As Long, pcbNeeded As Long) As LongPrivate Declare Function SetPrinter Lib "winspool.drv" _ Alias "SetPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, _ pPrinter As Any, ByVal Command As Long) As LongFunction SetDefaultPrinterOrientation(ByVal eOrientation As _ PrinterOrientationConstants) As BooleanDim bDevMode() As Byte Dim bPrinterInfo2() As Byte Dim hPrinter As Long Dim lResult As Long Dim nSize As Long Dim sPrnName As String Dim dm As DEVMODE Dim pd As PRINTER_DEFAULTS Dim pi2 As PRINTER_INFO_2' 获取默认打印机的设备名称 sPrnName = Printer.DeviceName '由于要调用SetPrinter,所以 '如果是在NT下就要求PRINTER_ALL_ACCESS pd.DesiredAccess = PRINTER_ALL_ACCESS'获取打印机句柄 If OpenPrinter(sPrnName, hPrinter, pd) Then ' 获取PRINTER_INFO_2结构要求的字节数Call GetPrinter(hPrinter, 2&, 0&, 0&, nSize) ReDim bPrinterInfo2(1 To nSize) As Byte lResult = GetPrinter(hPrinter, 2, bPrinterInfo2(1), nSize, nSize) Call CopyMemory(pi2, bPrinterInfo2(1), Len(pi2)) nSize = DocumentProperties(0&, hPrinter, sPrnName, 0&, 0&, 0) ReDim bDevMode(1 To nSize) If pi2.pDevMode Then Call CopyMemory(bDevMode(1), ByVal pi2.pDevMode, Len(dm)) Else Call DocumentProperties(0&, hPrinter, sPrnName, bDevMode(1), 0&, DM_OUT_BUFFER) End IfCall CopyMemory(dm, bDevMode(1), Len(dm)) With dm ' 设置新的走向 .dmOrientation = eOrientation .dmFields = DM_ORIENTATION .dmPaperSize = DMPAPER_A3 '将纸张大小设为A5,请自行更改所需大小 .dmFields = DM_PAPERSIZE '必须,否则无法设置纸张大小 End With Call CopyMemory(bDevMode(1), dm, Len(dm)) Call DocumentProperties(0&, hPrinter, sPrnName, bDevMode(1), bDevMode(1), DM_IN_BUFFER Or _ DM_OUT_BUFFER)pi2.pDevMode = VarPtr(bDevMode(1)) lResult = SetPrinter(hPrinter, 2, pi2, 0&) Call ClosePrinter(hPrinter) SetDefaultPrinterOrientation = True Else SetDefaultPrinterOrientation = False End If End Function 2、在command1中写入以下代码 Private Sub Command1_Click() Call SetDefaultPrinterOrientation(OrientPortrait) '...

在activereport中怎样用代码在数据之间画上表格(线条)呀
1、在模块中加入以下代码。
Option Explicit
Public Enum PrinterOrientationConstants
OrientPortrait = 1
OrientLandscape = 2
End EnumPrivate Type DEVMODE
dmDeviceName As String * 32

Dim hPrinter As Long
Dim lResult As Long
Dim nSize As Long
Dim sPrnName As String
Dim dm As DEVMODE
Dim pd As PRINTER_DEFAULTS
Dim pi2 As PRINTER_INFO_2' 获取默认打印机的设备名称
sPrnName = Printer.DeviceName
'由于要调用SetPrinter,所以
'如果是在NT下就要求PRINTER_ALL_ACCESS
pd.DesiredAccess = PRINTER_ALL_ACCESS'获取打印机句柄
If OpenPrinter(sPrnName, hPrinter, pd) Then
' 获取PRINTER_INFO_2结构要求的字节数Call GetPrinter(hPrinter, 2&, 0&, 0&, nSize)
ReDim bPrinterInfo2(1 To nSize) As Byte

Call CopyMemory(bDevMode(1), ByVal pi2.pDevMode, Len(dm))
Else
Call DocumentProperties(0&, hPrinter, sPrnName, bDevMode(1), 0&, DM_OUT_BUFFER)
End IfCall CopyMemory(dm, bDevMode(1), Len(dm))
With dm
' 设置新的走向
.dmOrientation = eOrientation
.dmFields = DM_ORIENTATION
.dmPaperSize = DMPAPER_A3

End With

lResult = SetPrinter(hPrinter, 2, pi2, 0&)
Call ClosePrinter(hPrinter)

SetDefaultPrinterOrientation = False
End If
End Function
2、在command1中写入以下代码
Private Sub Command1_Click()
Call SetDefaultPrinterOrientation(OrientPortrait)
'...
'在打印或预览之前直接调用SetDefaultPrinterOrientation 打印走向常数
End Sub别忘记加分哟。
