Forms and Classes

I have created a Master Detail form which uses a class module to add, edit ect.

I need to do some processing using sql on pressing the Update Button.

The sql does the processing ok, which effects my class (e.g. subsumes the detail lines from 4 lines to 1 line).

The problem I have got is that unless I drop the class and create a new one then the changes do not become evident on the screen.

Is there a way to refresh the class without having to close the class and recreate it.

I have tried:

Thanks For Your Help,

does your class have a requery method
where is the data visualized
which part of the form / class writes the data ..?

Write a sub in your class to re-initialize all lines and call that sub (ok, method) after your sql statement.

The class is the default class created by forms design wizard.

Id does have a requery method as below:

Public Sub Requery()
  DoingRequery = True
  DataMemberChanged "Primary"
  DataMemberChanged "Secondary"


  DoingRequery = False
  DataMemberChanged "Primary"
  DataMemberChanged "Secondary"
End Sub

The data is displayed on screen and on pressing the update button the processing takes place subsuming 4 lines into 1, which it does in the Access database.

The problem is the form still displays the 4 lines, even though 3 of them do not exist. If I close the class and recreate it will then show the changes, but this does not seam to be very efficient.

I hope this helps.

You can also try to close the connection and re-open it before your adoPrimaryRS.Requery line.
