在 Access 2010 中创建日历

Question

我一直在拼命寻找一种在 Access 中制作日历的方法。我知道这是可以做到的，因为我已经看到了很好的例子，但我不知道怎么做。 （另外，我的 VB 知识很少。）

基本上，我希望日历显示一个程序（我们称之为胶囊）被签出以及何时返回的日期范围。

• DateReserve - 胶囊的预订日期
• DateReturn - 胶囊需要归还的日期。

例如，如果胶囊 A 于 2014 年 6 月 1 日预订，并将于 2014 年 6 月 14 日返回，我希望日历直观地显示胶囊 A 在此时间段内不可用。这样一来，我们就不会意外重复预订胶囊。

通过我的许多谷歌搜索，我确实找到了 VB 代码，它可以调出一个非常漂亮的日历。我只是无法正确地获取代码以直观地显示胶囊将不可用的日期。 以下是我无法正常工作的代码部分之一：

Private Sub OpenContinuousForm(ctlName As String)
Dim ctlValue As Integer
Dim DaysOfMonth As Long
Dim DateReturn As Date
Dim DateShipOut As Date
Dim DateRangeForProgram As String

DateRangeForProgram = (DateDiff("n", [DateReturn], [DateShipOut]))
On Error GoTo ErrorHandler
ctlValue = Me.Controls(ctlName).Tag
DaysOfMonth = MyArray(ctlValue - 1, 0)

DoCmd.OpenForm "frmCapsulesSchedule", acNormal, , [DateRangeForProgram] = DaysOfMonth

ExitSub:
    Exit Sub
ErrorHandler:
    MsgBox "DATE SHIP OUT FAILED.", , "Error!!!"
    Resume ExitSub

End Sub

如果您需要我提供更多信息，请告诉我。

这是我用于日历的代码；任何你看到“教师”、“学校”或“胶囊”的地方都是你放置自己信息的地方：

我还有一个名为 modFunctions 的模块：

    Option Compare Database
Option Explicit

Public Function getFirstWeekday(lngFirstDayOfMonth As Long) As Integer

On Error GoTo Errorhandler
getFirstWeekday = -1
getFirstWeekday = Weekday(lngFirstDayOfMonth, vbMonday)

ExitFunction:
    Exit Function
Errorhandler:
    getFirstWeekday = 0
    MsgBox "There has been an error. Please reload the form.", , "Error"
    Resume ExitFunction
End Function

Public Function getDaysInMonth(lngFirstDayOfMonth As Long) As Integer

On Error GoTo Errorhandler
getDaysInMonth = -1
getDaysInMonth = DateDiff("d", lngFirstDayOfMonth, DateAdd("m", 1, lngFirstDayOfMonth))
ExitFunction:
    Exit Function
Errorhandler:
    getDaysInMonth = 0
    MsgBox "Something is wrong with the DATES!.", , "Date Error"
    Resume ExitFunction
End Function

Access All In One 看到了一个非常有用的 youtube 视频。这是示例中使用的数据库的link

Answer 3

您在 openform 命令的Where 条件中的语法不正确。

如果你用来过滤表单记录源的字段是[DateRangeForProgram]，它应该是"[DateRangeForProgram]=" & DaysOfMonth。

此外，如果您尝试将表单打开多天，您可能应该使用 Between 运算符。 datediff 函数的第一个参数指定一个时间间隔，您的时间间隔是分钟。

您应该发布其余代码，以便整个场景清晰。
