mysql - 在vb6中选择组合框的值后自动获取文本框的值

Question

我有一个包含 6 列的表 products，其中包括列 PRICE。我想要实现的是:

• 当我从组合框中选择一个值时，下一个文本框 Price 将自动从数据库表 products 中填充。

例如:表格产品

ProductName     Price
Mango           12
Apple           15

组合框值:

Mango
Apple

组合框文本框值:

Mango

PRICE 文本框值自动填充为:

12

尝试过的代码:

Private Sub Price()
Set Rs = New ADODB.Recordset
Set Cmd = New ADODB.Command

If txtProdName.txt Is Not Nothing Then

With Cmd
    .ActiveConnection = Conn
    .CommandType = adCmdText
    .CommandText = "SELECT price from products where productname=txtProdname.txt"
    Set Rs = .Execute
End With

txtPrice = Rs.Fields
 End If
 End Sub

我整天都在尝试这个，但这不起作用，如何纠正这个？真的很困惑。

试试这个:这个 serrve as sample...希望它有帮助

Private sub CboiPAQ_click()
Set rsiPAQs = New ADODB.Recordset 
With rsiPAQs 
.ActiveConnection = cnMHS 
.CursorLocation = adUseClient 
.CursorType = adOpenStatic 
.LockType = adLockPessimistic 
.Source = "SELECT location FROM iPAQs WHERE iPAQ=" & "'" & CboiPAQ.text & "'" 
.Open 
txtbox.text=rsiPAQs("location")
End With 
End sub
