根据在 Excel VBA 中输入文本框的搜索条件填充列表框

Populating a ListBox from search criteria entered into a TextBox in Excel VBA

这个问题我之前也发过,不过我觉得太复杂了,没解释清楚。这次我只是以一个简单的用户窗体为例。

我想通过在文本框中输入搜索条件来填充列表框。

我有三列:

A 列 = 图书证号

B 列 = 学生姓名

C 列 = 图书参考

我有一个用户表单:

TextBox = txtlcn(借书证号)

TextBox = txtpn(学生姓名)

TextBox = txtbr(供书籍参考)

命令按钮 = cmdfinddetails(查找详细信息)

我想做的是将文本框“txtbr”更改为列表框,这样我就可以查看学生是否有不止一本书借给他们。该过程将是:

  1. 一名学生在文本框“txtlcn”中输入他们的借书证号,然后 单击命令按钮“cmdfinddetails”
  2. 代码将搜索那个学生的名字和所有的书 推荐给他们。
  3. 图书参考资料将显示在列表框中。

我尝试了很多与 RowSource 相关的事情,但它总是列出每个学生的参考书目。下面是我的示例代码。

Private Sub cmdfinddetails_Click()
Set xSht = Sheets("Library")
        Lastrow = xSht.Range("A" & Rows.Count).End(xlUp).Row
        strSearch = txtlcn.Text
                    Set aCell = xSht.Range("A1:A" & Lastrow).Find

(What:=strSearch, LookIn:=xlFormulas, _
    LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
    MatchCase:=False, SearchFormat:=False)

      If Not aCell Is Nothing And txtpn.Value = "" Then
         GoTo libcardrefvalid      
     Else
MsgBox "Oops! That Library Card does not exist. Please try again.", Title:="We LOVE Reading ;-)"
txtlcn.Value = ""
        End If
    Exit Sub
libcardrefvalid:

row_number = 0
Do
DoEvents
row_number = row_number + 1
item_in_review = Sheets("Library").Range("A" & row_number)
If item_in_review = txtlcn.Text Then
txtpn.Text = Sheets("Library").Range("B" & row_number)
txtbr.Text = Sheets("Library").Range("C" & row_number)
End If
Loop Until item_in_review = ""

End Sub

如有任何帮助,我们将不胜感激。

谢谢。

假设您已经将 txtbr 更改为列表框,我可以使用以下代码使您的代码正常工作(查找学生姓名并添加引用到 txtbr 列表框的所有书籍)添加:

Private Sub CommandButton1_Click()
'clears the pupil name (caused an error if not done)
txtpn.Text = ""
Set xSht = Sheets("Library")
        Lastrow = xSht.Range("A" & Rows.Count).End(xlUp).Row
        strSearch = txtlcn.Text
                    Set aCell = xSht.Range("A1:A" & Lastrow).Find(What:=strSearch, LookIn:=xlFormulas, _
    LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
    MatchCase:=False, SearchFormat:=False)

      If Not aCell Is Nothing And txtpn.Value = "" Then
         GoTo libcardrefvalid
     Else
MsgBox "Oops! That Library Card does not exist. Please try again.", Title:="We LOVE Reading ;-)"
txtlcn.Value = ""
        End If
    Exit Sub
libcardrefvalid:

row_number = 0
'clears the listbox so that you have dont have a continuously growing list
txtbr.Clear
Do
DoEvents
row_number = row_number + 1
item_in_review = Sheets("Library").Range("A" & row_number)
If item_in_review = txtlcn.Text Then
txtpn.Text = Sheets("Library").Range("B" & row_number)
'Adds the book reference number to the list box
txtbr.AddItem Sheets("Library").Range("C" & row_number)
End If
Loop Until item_in_review = ""
End Sub

我制作了一个测试用户表单和一些模拟数据,这对我有用。希望您发现它也适合您。
