尝试使用Visual Basic将Word中的comboBox连接到Access中的数据库

问题描述

过去6个小时，我一直在为此工作，但我遇到了一个令人沮丧的错误.现在，我想在我的空白Word文档中添加一个组合框，并用在Access中创建的表中的字段中的数据填充它.我正在使用Visual Studio 2015作为我的IDE和Word 2013文档模板.

I've been working on this for the past 6 hours and I'm getting a frustrating error. For now, I want to add a combo box into my blank word document and populate it with a data from a field in a table I created in Access. I'm using Visual Studio 2015 as my IDE and the Word 2013 Document Template.

错误

我尝试过的内容

根据我读到的一些建议，我将目标CPU"更改为:从any PC更改为x86.但是，这一次我在启动时从Word收到了此错误.

From some advice I read, I changed by 'Target CPU': from any PC to x86. However, this time I received this error from Word upon starting up.

推荐答案

已经有一段时间没有实际应用了，但是，如果我的记忆正确的话，这应该可以解决:

Haven't been praticing for a while but, if my memories are correct, this should work :

Public Class ThisDocument
    Private Sub ThisDocument_Startup() Handles Me.Startup
        Dim cnn As New ADODB.Connection
        Dim rst As New ADODB.Recordset
        cnn.Open("Provider=Microsoft.Jet.OLEDB.4.0;" &
                 "Data Source=C:\Users\Danny\Documents\Employee Records1.accdb")
        rst.Open("SELECT Employee FROM Payroll;", cnn, ADODB.CursorTypeEnum.adOpenStatic)
        rst.MoveFirst()

    Dim ccList As ContentControl
    ccList = ContentControls.Add(Microsoft.Office.Interop.Word.WdContentControlType.wdContentControlComboBox)

    ccList.Title = "Select a Employee"
    ccList.SetPlaceholderText(,, "Please Select a Employee")
    Set ccList.RowSource=rst
End Sub
...

我无法对其进行测试，这可能需要一些调整...但是(据我所知)，RowSource一直是用DB行填充ListBox/ComboBox的最佳方法.

I'm not able to test it, this may require a bit of tweaking... but RowSource have always been the best way (as far as I know) to feed ListBox/ComboBox with DB rows.

这支持许多来源，例如ADO& amp; DAO记录集，数组...

This supports a lot of sources like ADO & DAO Recordsets, Arrays...
