将变量从一种形式传递到另一种形式 [英] Pass variables from one form to another

问题描述

我试图通过单击按钮将 ComboBox 中的名称从一种形式传递到另一种形式，但我似乎无法让它工作.我不习惯使用 MS Access，我相信这是一个简单的答案.这是我到目前为止所拥有的:

I'm trying to pass the name in a ComboBox from one form to another via button click and I cannot seem to get it to work. I am not accustomed to working with MS Access, and I'm sure its a simple answer. Here's what I have so far:

表格 A:

Private Sub Command104_Click()
On Error GoTo Err_Command104_Click

    Dim stDocName As String
    Dim stLinkCriteria As String

    stDocName = "Vol_Hrs"
    DoCmd.OpenForm stDocName, , , stLinkCriteria
    Forms.Vol_Hours.Search.Value = Me.Combo94.Column(0)

Exit_Command104_Click:
    Exit Sub

Err_Command104_Click:
    MsgBox Err.Description
    Resume Exit_Command104_Click

End Sub

表格 B:

Private Sub cmdAddNew_Click()
On Error GoTo Err_cmdAddNew_Click

    Dim stDocName As String
    Dim stLinkCriteria As String

    DoCmd.Close

    stDocName = "frmLookupScreen"
    DoCmd.OpenForm stDocName, , , stLinkCriteria
    Forms.frmLookupScreen.Combo94.Value = Me.Search.Column(0)

Exit_cmdAddNew_Click:
    Exit Sub

Err_cmdAddNew_Click:
    MsgBox Err.Description
    Resume Exit_cmdAddNew_Click

End Sub

推荐答案

当引用一个对象时，即文本框使用这个.

When referencing an object ie text box use this.

Forms!FormName!ObjectName.ObjectProperty = "Testing"

访问方法时使用它.

Forms!FormName.Form.Method.

话虽如此.当我在表单之间使用信息只是为了提取调用表单名称时，我发现它更容易.然后我就可以在那里访问呼叫表上的几乎所有信息.如果需要更新组合框或列表框、更改文本、重新查询等，我还可以将数据推送回调用表单.

Having said that. I find it much easier when I am using information between forms just to pull the calling forms name. Then I have access to almost all of the information on the calling form right there. I can also push data back to the calling form if necessary to update Combo or List boxes, change text, requery and so forth.

Private Sub Form_Load()

    Set frmPrevious = Screen.ActiveForm

    Me.tbText.value = frmPrevious.cbPassTest.value

End Sub

将该代码放入您正在调用的表单的 LOAD() 中，然后您就可以提取您需要的内容.

Put that code in the LOAD() of the form that you are calling then you can just pull what you need out.
