like using the backbuffer pointer.
Do I have to create my own D3D9 object and device or can I get it somehow from the backbuffer pointer?
A small example that plots a point on the backbuffer would be nice.

And how can I store a bitmap or the screen of a foreign window in a DBPRO image?

Here's example code for getting the backbuffer pointer and details.

This code fills the backbuffer with red, whether in 16 bit or 32 bit colour mode.

That code gives you access to the backbuffer using calls that are built into the DBPro runtime.

This next piece of code allows you to access images directly using DirectX calls. It's the code that I wrote for Dostej (I think) as an example. I've just cleaned it up to removes its dependency on the Interface library.

That's all that I've got to give away at the moment ... there may be more later

Thanks first!
But what is the pointer I get with "get backbuffer pointer()"?
I thought it was the pointer to a DIRECT3DSURFACE9 and tried(with passing "get backbuffer pointer()" as backbuffer to the function):
Quote: "IDirect3DDevice9 *ppDevice=0;
((LPDIRECT3DSURFACE9)backbuffer)->GetDevice(&ppDevice);
ppBackBuffer->GetDevice(&ppDevice);
ppDevice->ColorFill(ppBackBuffer,0,color);
ppDevice->Release;"

But it always crashed and I thought I either have to use DirectX 9.c instead of 9.0 SDK or it is because I did not initialize COM.
But you did not use any DirectX code in the backbuffer example.
It's late here now, I take a look at it tomorrow and try to understand it.

It's a pointer to the backbuffer memory - it's not a DX pointer at all.

If for some reason you need it, you might try and get the backbuffer surface from the GlobStruct (pHoldBackBufferPtr). That would make your code something like this:



You can also get the DX Device from the Setup dll using the function 'GetDirect3DDevice' that is included there.

I've never tried this myself, so let me know how it turns out
