Using Bitblt with a window which is not active

Hi,

I use Bitblt with a window and works great, but when the window doing the bitblt-ing is not the window with the focus, the bitblt routine sends whatever is on the SCREEN at the location pointed to by the bitblt routine.

So as i understand it, even though i am pssing a Hdc param it is Bitblting the screen Hdc in effect, as if another is on top the window bitblt-ing its covering it.

Any Ideas?

I had the same question earlier under posting "Copying an image into a Form".

I am still waiting for a reply.

Hey Nitro,
Hi and do you have an email?

HI NO2 and Zaf! Try to activate the window before you use bitblt.

Hi Kedaman, and thanks for your input too,

But.. As i'm using a timer control i'm not really keen on activating my window as the timer is set to approximately 10 milliseconds and boy , that just means that by the time the call is processed its time to do it again.

I was thinking more along the lines of juggling the memeory data directly, but do not know enough of the WinApi to do this, then again i might even be barking up the wrong tree.

Thanks to everyone who is giving me help

Then I don't know, The DC will be captured directly from the screen, not behind a window and what I know, there is no other direct ways of capturing the whole window (with it's controls)

I'm more after just some picture box controls rather than the whole window.

What exactly are you trying to do? by the sound of it there may be a better way of doing it.

I've wrote a prog to animate the start button completely in VB and it works super only....when another window is activated.....

How are you today Zaf Khan?

Thanks for the code the other day.

As for your questions, I tried everything to capture only a specific window, but still only got the entire screen. Therefore, I don't think we can capture a minimize window?

If I can find a way, I will sure email it to you.

See Ya for now!
