水晶报表设计时是横向打印的,但在输出到打印机时却变成了竖向打印.
我的代码是
CrystalReport1.ReportFileName="c:\Report1"
CrystalReport1.PrinterName="\\192.168.0.100\HPPrinter"
CrystalReport1.PrinterDriver="winspool"
CrystalReport1.PrinterPort="Ne00:"
CrystalReport1.Active=1

对了，以下代码是在显示报表的窗体中

Dim Report As New CrystalReport1

Private Sub Form_Load()

Report.PaperOrientation = crPortrait '纵向
Report.PaperOrientation = crLandscape '横向

End Sub

Private Sub Form_Load()

Report.PaperOrientation = crPortrait '纵向
Report.PaperOrientation = crLandscape '横向

End Sub

良芳,你好.
在打印报表的时候,我不知道这张报表是横向的还是竖向的

只要引用这个函数SetDefaultPrinterOrientation就可以了
，
