Title: json straight into NetWebBrowse
Post by: Rene Simons on December 07, 2018, 03:47:32 AM

Hi,

Is it possible or is there a way to move json data straight into a NetWebBrowse?  Or do I need to move the data into a memory table first?

Cheers,
Ren?

If you have jFiles you could load your JSON into a memory table and display in a browse.  Haven't done that myself but think it would be possible.

You could also load into a QUEUE and get and display the data in a field or fields in an existing browse.  The browse field itself would just be a field with only an equate. Probably as a string type.  In that field's value::somefield routine do seomthing like:

 packet.Append(myloadedJSONdata)

Seems doable.

Thanks Don,

I had figured that solution out already but was hoping for a more direct approach.
You mentioning the Queue option surprises me a bit. I Always thought that queues are not thread safe and therefore have to be avoided in NTWS.

Btw, I am looking forward to your presentation on apps on the 21st this month, as are probably a lot of people  ;).
No pressure there huh ?

Kind regards,

Ren

I think a queue in a local procedure would be pretty safe.  A qlobal queue?  Not so much.

Yeah, the most "direct" approach may be dropping the JSON in a mem table.  Fortunitly jFiles handles that well.

Useful in NetWebServiceMethods - not useful in Browses and Forms because those are "Event Handlers" not procedures.
