How to handle scroll down in the web page

[Mala]

Hi,
In order to capture a bitmap located at the end of the web page, I have to scrolldown the page (if not the code is not capturing the bitmap). How should I handle the scroll down operation in the script?

Can any one help me please?

Does the object not have VScroll or HScroll. If not let me know i will put up a function which will simulate mouse whell scroll.

No, it does not.

Allright..i will post the mouse wheel scroll function tommorow.

Mouse Wheel Rotation:

This will scroll a page as defined according to the mouse wheel rotation. A method which can be useful if you have not object scroll.

Code:

Extern.Declare micVoid, "mouse_event", "user32.dll", "mouse_event", micLong, micLong, micLong, micLong, micLong
Const MOUSEEVENTF_WHEEL = 2048 '@const long | MOUSEEVENTF_WHEEL | middle button up
Const POSWHEEL_DELTA = 120 '@const long | POSWHEEL_DELTA | movement of 1 mousewheel click Down<nl>
Const NEGWHEEL_DELTA = -120 '@const long | NEGWHEEL_DELTA | movement of 1 mousewheel click Up<nl>

'*****************************************************'*
' ** Max: MouseWheelRot(5); Min : MouseWheelRot(-5)
'*     positive and negative clicks exist, negative rotates wheel up: positive down
'*****************************************************

Sub MouseWheelRot(iClicks)

dim iLoop
dim bPos

if iClicks > 0 then
bPos = true
end if
for iLoop = 1 to abs(iClicks)
if bPos then
Extern.mouse_event MOUSEEVENTF_WHEEL,0,0,POSWHEEL_DELTA,0
else
Extern.mouse_event MOUSEEVENTF_WHEEL,0,0,NEGWHEEL_DELTA,0
end if
next
End Sub

Helps?

if the object does not support Vscroll and Hscroll methods.

you can use NextPage or NextLine or Set(ex: set 20) methods

Chandu,
I am really curious to know how the next page or line set method can be used to scroll. Would you please writeup the code with an example?

[chandu]

Code:

Window("").swfscrollbar("").set 20
Window("").swfscrollbar("").NextPage
Window("").swfscrollbar("").NextLine

u can use any of those methods as per ur requirement

How would you use this when you cant get the scroll bar object? Please read the questioners post.
