TXBrowse():PageUp() problem with ADSCDX.

[dutch]

Dear Antonio,

there is an error of ::PageUp() in TXBrowse() for ADS, when the items have more than number of lines in XBrowse. I use xHb.com/FWH 8.04/ADS.

I found when I press PageDown and PageUp, if there are a lot of items in XBrowse and effect only ADS.

Regards,
Dutch

Mr Duch

In one of your programs include this line

Code: Select all  Expand view

REQUEST ADSKEYCOUNT, ADSGETRELKEYPOS, ADSSETRELKEYPOS


and then build your project.

I normally include this line in the main program

Dear nageswaragunupudi,

It's fixed. I've this line in my main program but it doesn't help. What is the different between EXTERNAL and REQUEST ?

Code: Select all  Expand view

external ADSKEYCOUNT, ADSGETRELKEYPOS, ADSSETRELKEYPOS


Another strange thing
When I ageDown() until the last line and ageUp(), then it can go to the first page but it cannot go to the first line (item). If I press :GoUp() or :GoDown() and then I will be able to press ageUp() to first line.

In my view both have the same effect of requesting the linker to link these symbols ( functions ).

It seems thats how the authors of the program have written it. If we express here what is the behavior we all like to have, I hope Mr Antonio can provide it in the next release. Meanwhile we may work out a fix if possible

I put in REQUEST. It fixed but EXTERNAL got an error.

I try to remove this following line, it fixed but somewhere with this line without problem. I'm not quite understand.

Code: Select all  Expand view

::bChange := {|| oBrw:Refresh() }


Anyway, thanks a lot for your helpful.

I dont see why should you get an error. I use either external or request and both work fine for me.

Unless you are referring to another browse, this slows down browse a lot. Because refreshing entire browse with every row movement costs lot of time.
