Output to a foreign DirectX application

Case is this:

There is a - commercial - game which uses DirectX. Usually it's played in Fullscreen mode.

Is it possible to write a PureBasic program that generates output in that game's screen; most likely text? I tried a little bit with the BitBlit function...

it should be, but its complicated.

I'll asume your using DB or BB
1 - you will need to lock up the display via a Lock Pixcel command or simular

2 - obtain a pointer to the screen
in DB its a pointer to bitmap 0

3 - pass this pointer to your DLL
along with the screen width,height,depth

4 - now all you need to do is place your pixcels
into this bitmap as raw memory. this gets complicated in DB.
for example, to make a dot at X,Y
Color=rgb(r,g,b) use whatever color...
mem=X*Depth+depth*width*Y
poke *bitmap+mem,color
at least i think that how it goes
this is in psudo code
you may need to find a way to ensure that your color bitdepth
does not excede the stated bit depth.

5 - upon return from your DLL
unlock the buffer, discard the pointer and procede normally.

that should provide the bassis for proceding into the unknown.

Thanks for your reply, waffle.

You are right. Complicated, or better said: too complicated for me at the moment.

I was in the hope that there is probably a snippet for that; but it's not that important anyways. Enough stuff else to try out in PureBasic. Love it.

Maybe I'll give it another try after I realized all the other stuff that came to my mind. So little time... :-/
