C# Capture Screen behind my form without disabling areo for windows 7 -

for weeks have been looking through forums, google , other place find , far cannot find answer. no expert @ coding fun , although more frustrated still keeps me busy have come problem cannot solve , how 1 capture cursors position or screen matter withought having form in it?

things have tried:

method 1

allowtransparency = true; transparencykey = color.empty; opacity = 99; 

for work requires aero feature disabled not , not want in app

method 2:

opacity = 0; docapture(); opacity = 100; 

this causes flickering when timer intervel set 100 or intervel matter

method 3:

hide(); docapture(); show(); 

this causes same flickering above

all methods have been found on site take screenshot of screen behind form? how can capture screen without form? capture screen not current form in c#?

method 4: using magnifyer.dll causes random black capture , buggy cannot work , best post question api.

btw using ms visual c# 2010 express running windows 7 64 bit

so far best method work first 1 prefer not have use aero needs disabled , makes whole screen flicker when been disabled , enabled.

is there or there way caputer message of wm_paint message or other message before form redrawn take screenshot form redraw? if point me in right direction or provide code how beond understanding of how go , it, can capture wm_paint , wm_erasebkgnd messages unsure or go there insite apreciated
