Disable Scrollbar ? (Static Page)

I’m want to disable scroll bar on “Page instfiles” but I can't figure out how…

I’m trying using this: but no effect.

FindWindow $R0 "#32770" "" $HWNDPARENT

GetDlgItem $R1 $R0 1016

System::Call 'User32::ShowScrollBar(i,i,b) ($R1,SB_BOTH,0)'

Where its mistake?
Thanks

I’m found how… scrollbar seems to disabled but still visible… 🙁

!define SB_BOTH 3

!define ESB_DISABLE_BOTH 3



System::Call 'User32::EnableScrollBar(i,i,i) ($R1,${SB_BOTH},${ESB_DISABLE_BOTH})'

System::Call 'User32::ShowScrollBar(i,i,b) ($R1,${SB_BOTH},0)'
