Ok, Thank you.

Hi,

I'm already using Myquery.SaveToXml and load to a VirtualTable, but the performance is not high for save to xml.

Adoquery.savetoFile('myfile.vtd") is so fast and the size of the file very small.

I didn't found the implementation of savetoxml.

"(please note that you can implement data export to other formats from your side)"
I didn't found how to do that.

Thank you.

Hy,

I would like use tmyquery.Savetofile like Tadoquery but i can not found this method.

There is a equivalent method ?

Thanks.

Hello,

I ve just installed mydac 10.3.2 for Rad Studio 10.4 Delplhi on Windows 10 64.

When i boot on Windows it's ok .

But It's not a Trial Version.

Ok Thank you for the reply.

But how can i use it to have the last sort instead of the original sort?

Hello,

I'm trying to to manage the order of my records in my virtualtable;

I did it like that :

virtArticlesDoc.indexfieldNames := '';
// process ordering
virtArticlesDoc.indexfieldNames := 'ordre';

But when i set indexfieldNames to empty, my virtualtable is sorted..
How can i really disable the sorting..

Thank you.

Hy,

I have the same problem, there are a solution now ?

Thank you.

Hy,

How can i iterate from a tvritualtable without change the active record.

for exemple :

Loop over the all records to calculate a sum..

Thank you.

Hy,

EDIT :

the event field on change is triggered if a deleted the "assign form dataset' .



I'm testing tvirtualtable, but the event Onchange of a field doesn't triggered.

I created in design and loaded from a dataset like :

myvirtuale.assign(mydataset);

The onchange of a dataset work fine but not in virtuale table.



Thank you.

ok,

i will test it, thank you

"detected problems with app native libraries unauthorized access to lib.ssl".

How can i dot that?
