question on how to delete "tab" of Tfolder

[kim yong woo]

Hello everybody,
I am not a professional programmer, doing programming as a hobby.
Recently, I am interested in TFolder class since I were allowed to maniplulate part of screen without changing whole screen.

To maximize it's usage, I tried to delete 'tab' parts, but, it generated 'error'.

REDEFINE FOLDER oFolder ID 100 OF ::oDlg PROMPTS "Product","Molecule" DIALOGS "MMGPAGE1", "MMGPAGE2"
-> it worked!

REDEFINE FOLDER oFolder ID 100 OF ::oDlg DIALOGS "MMGPAGE1", "MMGPAGE2"
-> I tried to delete "Product", "Molecule" tabs, but, it returned following error description:
Error Base/1111 Argument errer: Len
Called from Len(0)
Called from TFolder:Redefine(194)
Called from TMain:new(56)
Called from Main(33)

Please help me.

Thanks.

Hello Kim,

please have a look at FWH\samples\Genfold.prg
As well You can also Enable / Disable a Folder-page :
oFld:aEnable = { .t., .t., .f., .f. } // .t. = enable, .f. = disable

Regards
Uwe
