I have been dragged out of retirement to write a simple accounts package for a local charity and am realising how much I have forgotten.
The main data entry screen has the usual clutch of controls - a grid, textboxes, combos, etc. All the controls are on the form and as I set each one up I run the app to check for bugs and typos. I am starting to get some odd behaviour, I have an option group with 2 options. The Interactive Change method has some code which sets the active page of a pageframe as shown below:
ThisForm.pgfIncExp.ActivePage = This.Value ThisForm.Refresh
It has been working fine for a couple of days but suddenly if I select Option 2 from Option 1 I get an error message which says that ThisForm.Refresh is not a recognised command but selecting the other way, which runs the same code, doesn't give an error. I have started saving a copy of the form after each successful run and find if I replace the SCX and SCT files with the earlier version the problem goes away for a while then reappears.
Has anyone come across anything similar?

John, Just try and use RaiseEvent(Thisform, "Refresh")
I know it shouldn't cause any problem but it will allow you to trace into it.
Sure you haven't got any form subclassing code somewhere?

Thanks Dave. I've replaced the line with RaiseEvent(Thisform, "Refresh") and it works fine. I just need to wait for it to fail again :-) I'd not heard of RaiseEvent before, what can I expect to happen when it fails again?
I'm certain I haven't any subclassing although all my controls are subclasses of the originals but there is very little further code needed. The form has 2 methods to enable and disable all the controls on the form but I have been using them for years without any problem.

John, That implies that you have some code in the refresh event of the form as the method code is working fine (As can be shown in the RaiseEvent()). Remember that even a single space in the Refresh method effectively invalidates the standard refresh code. It is very easy to have a single space in the Refresh() method and not notice that it is there. Another way to ensure it works is to put
DoDefault() Return
as the only code in the method.

John,
Another way to handle this would be code in two places. First no code here. Set the ControlSource to the ActivePage property. Then in any control on the pages, add code to the UIENABLE event, when lEnable is true, THIS.Parent.Refresh()
We actually added to the PageFrame subclass, during the INIT, it adds a hidden control to each page. This control has that code in it.
Just another way to do it.

Hi Tracy,
That is getting seriously technical :-) I'll see how it goes.

ThisForm.pgfIncExp.ActivePage = This.Value ThisForm.Refresh
Probably already thought of but the proper syntax of the command is:
ThisForm.Refresh()
(ie, with parentheses)
Such code would run semi-reliably without the parens in VFP 6 but less so in later versions. I have had a few instances in which bad code generates errors under some circumstances but not others, in seemingly random fashion, owing most likely to the behavior of the compiler.
