如何从ComboList(字段名称)中选择值到textBox,以便我可以使用VBScript在查询中使用逗号分隔的文本框值?
Combo1.AddItem("Field1")
Combo1.AddItem("Field2")
Combo1.AddItem("Field3")
Combo1.AddItem("Field1")
所以我可以在查询中使用它:
SELECT Field1, Field2, Field4 FROM TableName;
答案 0 :(得分:0)
这将添加和删除项目。
Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
Dim selectedField As String = ComboBox1.Items(ComboBox1.SelectedIndex)
If (selectedField.Length > 0) Then
If (query.Contains(selectedField)) Then
query = query.Remove(query.IndexOf(selectedField + ","), (selectedField + ",").Length)
Else
query += selectedField + ","
End If
TextBox1.Text = query
End If
End Sub
