using user32.dll defined functions: GetScrollInfo

[cuitino]

Hello again,

I am attempting to receive the scrollbar range of a form, say in notepad.

This is what I came up with:


Macro Macro6

Code:

Copy      Help

int w=win(" - Notepad" "Notepad")
Acc a.Find(w "SCROLLBAR" "Vertical" "class=Edit[]id=15" 0x1035)
int hwndScrollbar=child(a) ;;Toolbar handle

def SB_CTL 2
def SIF_RANGE 0x1
def SIF_PAGE 0x2
dll user32 #GetScrollInfo hWnd nBar SCROLLINFO'lpsi 
SCROLLINFO tSI
tSI.cbSize=sizeof(SCROLLINFO)
tSI.fMask= SIF_RANGE | SIF_PAGE

GetScrollInfo(hwndScrollbar SB_CTL tSI)
out tSI.nMax

I get the following error:

Error (RT) in Macro6:  Exception 0xC0000005. Access violation. Cannot read memory at 0x1C. In USER32.dll at 0x7530A8EE (0x752D0000+0x3A8EE).    

Any advice will be much appreciated,
Cuitino
