我们如何通过仅使用代码生成器从 ms-access 中的表源更新特定字段来填充其他表单字段

Question

I have the below problem:

• I have a student table in access with field class, classfee and leaves
• and another table namely classes with fields class, monthlyfee and leaves
• I have related both tables with a one to many relationship
• now i have created a form as shown in images and i want when i choose class from the drop down box the leave and fee field should come up automatically from the classes table fields (monthlyfee and leaves)

Problem explained in this image

Code explained here

tables relationship here

Private Sub Class_AfterUpdate()

Me.Fee.RowSource = "SELECT ClassFee FROM" & _
                   "Classes Where Class_ID = " & Me.Class

Me.Fee = Me.Fee.ItemData(0)

End Sub

Answer 1

You forgot the error message that probably tells about a syntax error, as you missed the space here:

Me.Fee.RowSource = "SELECT ClassFee FROM " & _
               "Classes Where Class_ID = " & Me.Class
