Capture Screen without showing it

[wolferl19]

my problem:

i want to create a chart with the activex control mschrt32.ocx and save the window output to a bmp file. if the window is visible than i can capture my window with the hDC property.
but i want to create and save the chart in the background (noone should see this).
is there a chance to solve this problem with the AutoRedraw-Property of the Form-Object ?

Please give me support.

it works quite yery well. -> thank you, i did it up to now in c++.

but the problem is that i have to show the output on the screen to capture it. if i don´t show it i´m not able to save it.

i need a method to put the output in a file instead of the screen (like printing). maybe link the output in another dc. i must not show the output on the screen!
