... It allows you to upload files and you can query about them. In example, I uploaded several Harbour core files and asked it for optimization, improvements, etc. very interesting! :-) Don't forget to select gpt-4-1106-preview from the left menu

... What we can do is to read from disk only once per image file and when repainting the same cell, access the image from the memory. That is the best optimization we can do. Based on this approach, I made a test program accessing image files from \fwh\bitmaps folder. In this program I have focused ...

... to test the vBargetAction with scopes. But before I try this, I wait for the information that Mr. Rao will provide in the next days depending the optimization rules of filters in DBFCDX, since that is what I use. My change from DBFNTX to DBFCDX some while ago was only in linking the cdx files, ...

... if this code is still optimised for the current version of FW. The code is somewhere from the forum, but sure a longer time ago. Changes needed ? Optimization has nothing to do the version of FWH. Optimization of filters is dependent of (x)Harbour RDD. DBFCDX and ADS optimize filters if the filters ...

Yes, but this is an optimization, not a clarification of the code. And it's probably not much effective.

It does not matter at all whether you use HDO, ADO, Dolphin, TMySql or FWH library. None of them help us to optimize our sql queries. Optimization of queries is something we need to do ourselves. For this purpose, no point discussing which library to use. I do not know how big is `catalogo` ...

I can't see any optimization in the following sample: #include "Fivewin.ch"REQUEST DBFCDXFUNCTION MAIN()    LOCAL nSec    LOCAL n, i    RDDSETDEFAULT( "DBFCDX" )  ...

... FOR conditions in Indexes. The purpose of indexes is also to speed up queries (FILTERS). The RDD does not consider indexes with FOR conditions for optimization. That way we forgo some benefits of having indexes. As I suggested please use FILTER TO !DELETED(). There is not much performance impact ...

... (not the entire database) are read from the server. But to use this effectively, the programmer should first know that there is this kind of optimization available and then should understand how the optimization works and then should plan the indexes and construct the filter expressions to ...

... at all even if a "FOR DELETED()" tag exists. c)If the parameter is set to .T., recycling is compulsorily attempted. For pursposes of optimization, ( i) if a "FOR DELTED()" index exists, that index is used. ( ii) If an index tag with expression "DELTED()" exists, ...

We do not think TDatabase methods need external help for optimization.
We recommend using them directly as FWH provided.

Very interesting discussion among experts about optimization of string operations, avoiding memory fragmentation, etc. Though this topic interests me too, at the moment, I am not discussing that topic. The discussion appears to have started with ...
