Dynamic Hyper File Context

Hello All

I would like to be able to programatically set the Hyper File Context for a window on the fly.

At the moment it must be preset in the window editor.

If you could set it as required it would make it much easier to use windows in mutliple modes.
e.g. If I want to display list of customers in a table as an entry point to an editing screen then I would turn of the HF Context, but if I used that same table screen as a lookup window and I don't want the record pointers moved in my calling window I would turn on the HF Context.

Hi Al,

I suppose you could use HSavePosition(), HrestorePosition and HFreePosition() for this, or didn't I understand your request right ?

Hello Stefan

The big problem with HSavePosition is that it does not save the data in the record buffer, only the position of the record pointer.

eg Open an edit window and filetoscreen(), then the operator changes some values. If you temporarily store those change in the buffer and then open the same data file in another window and select another record, the data in the first window is lost unless you open the second window with a new context. The issue for me is that sometimes I want to open the second window in the same context and other times with a new context.

Hi Al,

I think that HSavePosition(<Filename>,"",hSaveItems) will save the data in the record buffer ? I use it on a regular basis.

Quote from the help of HSavePosition:

<Options>: Optional integer constant

Enables you to configure the backup:

hSaveItems
Saves the values of the items in memory when HSavePosition is used. These values will be restored when calling HRestorePosition.

Sorry,

the filename got lost, the statement must be:

HSavePosition(MyFile,"",hSaveItems).

Hello Stefan

Thanks for the update.
I checked back and that option came in with V10 and I obviously missed it or didn't realise the significance of it to save the record buffer.

It will certainly enable the full context to be saved in a dynamic fashion as I required.

Regards
Al
