;***********************Cell Borders (box)********************************.
IfEqual,Line,0,SetEnv,Line,-4142 ; Excel constant for no border
Loop, 4{
PXL.Application.ActiveSheet.Range(RG).Borders(A_Index+6).Weight := Weight
PXL.Application.ActiveSheet.Range(RG).Borders(A_Index+6).LineStyle := Line

XL_Handle(ByRef PXL,Sel){
ControlGet, hwnd, hwnd, , Excel71, ahk_class XLMAIN ;identify the hwnd for Excel
IfEqual,Sel,1, Return, PXL:= ObjectFromWindow(hwnd,-16).application ;Handle to Excel Application
IfEqual,Sel,2, Return, PXL:= ObjectFromWindow(hwnd,-16).parent ;Handlle to active Workbook
IfEqual,Sel,3, Return, PXL:= ObjectFromWindow(hwnd,-16).activesheet ;Handle to Active Worksheet

ObjectFromWindow(hWnd, idObject = -4){
(if Not h)?h:=DllCall("LoadLibrary","Str","oleacc","Ptr")
