I want to check color point on control in hided window..

this code from me...

MessageRequester("Ready ?" ,"")
sysviewDC = GetDC_( hwndSysview )
color = GetPixel_( sysviewDC, x, y )

color will return -1 alway if window is background (or not shown)

but if window is foreground color will return true value of DC color point

....problem : I want to get color point from hwnd but it's hinding !!

any one have idea ? (-_-')

A window which is hidden has no colour. (Duh) Eventually you can save the window's surface to a bitmap each time you minimize it.

Can you read the color before opening the Requester?
