之前我已经发布了这个问题,但是,我认为它过于复杂,我没有很好地解释它。这次我只是以一个简单的UserForm为例。
我想通过在文本框中输入搜索条件来填充ListBox。
我有三列:
A栏=图书馆卡号
B栏=学生姓名
C列=图书参考
我有一个UserForm:
TextBox = txtlcn(图书馆卡号)
TextBox = txtpn(对于学生姓名)
TextBox = txtbr(用于图书参考)
命令按钮= cmdfinddetails(查找详细信息)
我想要做的是将TextBox'txtbr'更改为ListBox,以便我可以看到学生是否有多本书借给他们。这个过程将是:
我尝试过很多与RowSource有关的事情,但它总是列出每个学生的书籍参考。以下是我的示例代码。
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
非常感谢任何帮助。
谢谢。

假设您已将txtbr
更改为列表框,我可以使用以下添加内容使您的代码正常工作(查找学生姓名并添加引用到txtbr
列表框中的所有书籍):
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。希望你也能发现它也适合你。
