如何在Excel VBA中创建一个搜索过滤器，以便在键入单词时在列表框中显示搜索结果? [英] How to make a Search Filter in Excel VBA that displays search result in the ListBox while typing a word?
本文介绍了如何在Excel VBA中创建一个搜索过滤器，以便在键入单词时在列表框中显示搜索结果?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我现在正在尝试在用户窗体中进行为期数周的高级搜索，在输入值时它会过滤并在ListBox上显示结果.但是以某种方式，我用作过滤器的ComboBox已经具有下拉功能.
I'm trying to make an Advanced Search now for weeks in my Userform where it will filter and display the result on the ListBox while typing a value. But somehow my ComboBox that serves as a filter has a dropdown function already.
我不知道如何使它像我想要的那样.
I have no idea how can I make it like the way I wanted it.
我的用户窗体包含8列.
My UserForm contains 8 columns.
这是ComboBox过滤器的现有代码
Here is the existing code for the ComboBox filter
Private Sub cmbSearch_Change()
'The function of this code below is for the user to click a value from the ComboBox and then the result will be displayed on the TextBoxes and ListBox.
x = Sheets("DATA STOCK").Range("A" & Rows.Count).End(xlUp).Row
For y = 2 To x
If Sheets("DATA STOCK").Cells(y, 1).Text = cmbSearch.Value Then
cmbSchema.Text = Sheets("DATA STOCK").Cells(y, 1)
cmbEnvironment.Text = Sheets("DATA STOCK").Cells(y, 2)
cmbHost.Text = Sheets("DATA STOCK").Cells(y, 3)
cmbIP.Text = Sheets("DATA STOCK").Cells(y, 4)
cmbAccessible.Text = Sheets("DATA STOCK").Cells(y, 5)
cmbLast.Text = Sheets("DATA STOCK").Cells(y, 6)
cmbConfirmation.Text = Sheets("DATA STOCK").Cells(y, 7)
cmbProjects.Text = Sheets("DATA STOCK").Cells(y, 8)
UserForm1.listHeader.RowSource = "A" + CStr(y) + ": H" + CStr(y)
Exit For
End If
Next y
End Sub
预期结果:
- 用户在ComboBox中键入单词(由于下拉菜单功能，我选择了ComboBox作为过滤器)
- 用户输入时，它将显示结果到列表框.
问题是我不知道如何创建这种搜索过滤器，即使我的ComboBox中已经具有下拉功能，也可能创建该搜索过滤器
The problem is I don't know how to create that kind of search filter and if it is possible even though I already have a dropdown function in my ComboBox
推荐答案
看到您已经为此工作了数周.
Saw that you've been working for weeks on this.
我已经重构了表单的代码，并实现了您一直在寻找的功能.
I have refactored your form's code and implemented the functionality you've been looking for.
作为我对其他问题的另一种回答，我认为与列表范围内的项目相比，在列表框中添加和删除项目要容易得多. (
As my other answer to your other question, in my opinion it's easier to work adding and removing items to the listbox, rather than working with excel ranges. (How to fix this bug in my code that doesn't allow me to update other columns in excel userform?)
重要说明: -我已将工作表中的数据转换为Excel结构表(Ctrl + T) -我取了您以前的文件之一，因此表中的信息可能已过时 -测试我还修改了一些数据 -我建议您复制并粘贴最新数据，然后将其替换到表中
Important remarks: - I've converted the data inside the sheet to an Excel Structured Table (Ctrl + T) - I took one of your previous files, so the information you have inside the table may be out of date - Testing I also modified some of the data - I suggest you copy and paste your most recent data and replace it inside the table

我介绍了将Excel数据加载到用户窗体内的列表框中的基本操作(创建，读取，更新，删除和搜索/筛选).
I covered basic operations (Create, Read, Update, Delete and Search/Filter) with Excel Data loaded into a Listbox inside a Userform.
这是表格后面的代码:
Option Explicit
' Code updated
Private Sub btnDelete_Click()
Application.EnableEvents = False
Call mCode.Delete
Application.EnableEvents = True
End Sub
' Code updated
Private Sub btnView_Click()
Application.EnableEvents = False
Call mCode.Read
Application.EnableEvents = True
End Sub
' Code updated
Private Sub cmbAdd_Click()
Application.EnableEvents = False
Call mCode.Create
Application.EnableEvents = True
End Sub
' Code updated
Private Sub cmbClearFields_Click()
Application.EnableEvents = False
Call mCode.ClearControls
Application.EnableEvents = True
End Sub
' Code updated
Private Sub cmbSearch_Change()
Application.EnableEvents = False
Call FilterList(Me.listHeader, Me.cmbSearch.Text)
Application.EnableEvents = True
End Sub
' Code updated
Private Sub cmbUpdate_Click()
Application.EnableEvents = False
Call mCode.Update
Application.EnableEvents = True
End Sub
' Code updated
Private Sub CommandButton5_Click()
Application.EnableEvents = False
Call mCode.ClearList
Application.EnableEvents = True
End Sub
' Code from this event was removed
Private Sub listHeader_Click()
End Sub
' Code added
Private Sub listHeader_DblClick(ByVal Cancel As MSForms.ReturnBoolean)
Application.EnableEvents = False
Call mCode.LoadControls
Application.EnableEvents = True
End Sub
' Code partially updated
Private Sub UserForm_Initialize()
Me.cmbSearch.List = ThisWorkbook.Sheets("PRESTAGE DB").ListObjects("TableData").ListColumns(1).DataBodyRange.Value
Me.cmbEnvironment.AddItem "DEV"
Me.cmbEnvironment.AddItem "UAT"
Me.cmbEnvironment.AddItem "SIT"
Me.cmbEnvironment.AddItem "QA"
Me.cmbEnvironment.AddItem "PROD"
Me.cmbAccessible.AddItem "Y"
Me.cmbAccessible.AddItem "N"
Me.cmbIP.AddItem "1521"
Me.cmbProjects.AddItem "DP - proposed for DEV/SIT"
Me.cmbProjects.AddItem "PH EFUSE SIT"
Me.cmbProjects.AddItem "MyAXA SG DEV/DIT"
End Sub
这是名为mCode的模块中的代码:
And this is the code inside a module called mCode:
