B4J Question ProgressDialogShow just flash

[Marco Maria Vilucchi]

Hi,
I'm using iHud library
When I use ProgressDialogShow, it only flash...
Example:

ProgressDialogShow
Read 200 records
ProgressDialogHide

It just flash at the end of read istruction

It seems I wrote:

Read 200 records
ProgressDialogShow
ProgressDialogHide

What appens?
Thx
Marco

The main thread should be free for the dialog to show. How long does it take to read the 200 records? It should be quite fast.

If it is slow, and you can't optimize it then you need to use SQL.ExecQueryAsync instead.

I want ProgressDialogShow works during reading, while user waits for a response
It's possible that records were 2000....
How can i do?
Thx
Marco

See my answer above. The first step is to optimize your queries. Reading 2000 records can be a very quick operation if the query uses an index for example.

If it is too slow then you need to use the async method instead.

Sorry,
I wrong Forum
I'm using B4I.... I know ExecQueryAsync function isn't available in B4I.
I apologize for my error.
