vim latex setup (most updated)

tried so many times and searched all over google but no one works,
finally find out by myself
so let me put it here:

in sumtrapdf, settings, option, inverse search put:
"C:\Program Files\Vim\vim73\gvim.exe" --remote-silent +%l "%f"

in latex-suite, search in ftplugin/latex-suite/compiler.vim and modify
as follows:

original:
if (has('win32') && (viewer =~? "^ *yap\( \|$\)"))
let execString = 'silent! !start '. viewer.' -s
'.line('.').expand('%').' '.mainfnameRoot

New:
if (has('win32') && (viewer =~? "^ *yap\( \|$\)" || viewer =~? "^sumatrapdf"))
if viewer =~? "^sumatrapdf"
let relativeFile=substitute(expand("%:p"),
Tex_GetMainFileName(':p:h').'/', '','')
let execString = 'silent! !start SumatraPDF
-reuse-instance "'.mainfnameFull.'.'.s:target.'" -forward-search
"'.relativeFile.'" '. line('.')
else
let execString = 'silent! !start '. viewer.' -s
'.line('.').expand('%').' '.mainfnameRoot
endif

in vimrc put:
let g:Tex_DefaultTargetFormat = 'pdf'
let g:Tex_CompileRule_pdf='xelatex --synctex=-1 -src-specials
-interaction=nonstopmode $*'
let g:Tex_ViewRule_pdf='SumatraPDF'
let g:Tex_MultipleCompileFormats='pdf'

Okay, thats it, no bother, forward(\ls) and backword searching (double click)
