摘　要:如果您想判断一个数据库中的报表是否打开，您需要检查报表连接，如下函数可以做到。
正　文:

如果返回true,则报表是打开，false则报表没有打开。
Sub fCheckReport(strReport As String) As Boolean
    Dim rpt As Report
    fCheckReport=False
    For Each rpt In Reports
        If rpt.Name=strReportName Then fCheckReport=True
    Next rpt
End Function

打印当前窗体上的记录的报表
DoCmd.OpenReport "rptName", acViewNormal, , "[UniqueFieldOnReport]=Forms![frmName]![UniqueFieldOnReport]"

全部范围内,从第二张打到第五张,高品质打印,印三份
DoCmd.PrintOut acPrintAll, 2, 5, acHigh, 3, False

生成间隔背景颜色的报表
要求:生成间隔背景颜色的报表，奇数行的背景颜色为兰色,偶数行的背景颜色为白色,兰白相间,方便查看.
方法:根据行号进行判定,设定背景色.
1 设计报表INVOICE ,必须有行号字段NO(由1开始连续的系列号)
2 设计宏SETINVOICECOLOR,条件及操作如下
条件    ([Reports]![INVOICE]![NO]) Mod 2=1
操作    Setvalue
         项目 [Reports]![INVOICE].[Section](0).[BackColor]
         表达式1632256
条件    ([Reports]![INVOICE]![NO]) Mod 2=0
操作    Setvalue
         项目 [Reports]![INVOICE].[Section](0).[BackColor]
         表达式16777215
3 设计报表INVOICE ,选定节Detail的属性中,事件"打印"为宏 SETINVOICECOLOR.
4 打印报表INVOICE,生成间隔背景颜色的报表.

报表奇偶页不同颜色显示
Option Compare Database
Option Explicit
Dim i As Integer
Private Sub 主体_Format(Cancel As Integer, FormatCount As Integer)
    i = i + 1
    If i Mod 2 = 0 Then
        Me.主体.BackColor = 12632256
    Else
        Me.主体.BackColor = 16777215
    End If
End Sub

如何在报表中产生递增的顺序编号
在报表的细节上放一个文本框，控件源等于=1 并设"运行总和"属性设置为“工作组之上”即可。

给输出的报表加个边框
Private Sub Report_Page()
Line (0, 0)-(ScaleWidth, ScaleHeight), , B
End Sub

报表页小计
在报表的主体节复制、粘贴一个要统计的数据的文本框TEXT1，属性的数据----运行总和为“全部之上”，可见性可设为“否”；
在页脚建一未绑定文本框TEXT2，用来显示页合计数据值；

在报表的页脚的打印事件中写：
Dim x As Single
Me.TEXT2 = TEXT1 - x
x = TEXT1

实际上是每个记录的工资累计。每页结束后把这个值赋给X，下页再合计后减去X就是本页合计，以此类推。

每页固定打印7行，数据不足时用空行补齐。
最好还是用Line语句。在报表的“打印页前”事件中输入下面内容。

Private Sub Report_Page()
Dim rpt As Report, lngColor As Long
Dim i As Integer
Set rpt = Reports!当前报表
rpt.ScaleMode = 7
lngColor = RGB(255, 0, 0)
rpt.Line (2.503, 2.5)-(4.735, 6.588), lngColor, B
rpt.Line (7.354, 2.5)-(9.074, 6.588), lngColor, B
rpt.Line (10.317, 2.5)-(12.037, 6.588), lngColor, B
rpt.Line (13.81, 2.5)-(15.952, 6.588), lngColor, B
rpt.Line (19.123, 2.5)-(19.123, 6.588), lngColor
For i = 1 To 7
rpt.Line (0.4, 2.5 + (i - 1) * 0.584)-(19.123, 2.5 + i * 0.584), lngColor, B
Next i
End Sub

应用筛选打印报表以及取消后
Sub 打印发货单_Click()
' 这段代码由“命令按钮向导”创建。
On Error GoTo Err_PrintInvoice_Click

    Dim strDocName As String

    strDocName = "发货单"
    ' 打印“发货单”报表，使用“发货单筛选”查询打印当前订单的发货单。
    DoCmd.OpenReport strDocName, acViewNormal, "发货单筛选"

Exit_PrintInvoice_Click:
Exit Sub

Err_PrintInvoice_Click:
    ' 如果用户取消操作，不显示错误消息。
    Const conErrDoCmdCancelled = 2501
    If (Err = conErrDoCmdCancelled) Then
        Resume Exit_PrintInvoice_Click
    Else
        MsgBox Err.Description
        Resume Exit_PrintInvoice_Click
    End If

End Sub
