If there anyway to do a screengrab from within a DBPro exe?

eg. press a key and everything on screen - text, sprites, 3d objects
is held in memory so it can be saved and reloaded at a later date, or used as a texture on an object?

I haven't the faintest clue how to do this!

You're asking for three different things here.

1) How to screen grab from a running DBPro program.
2) How to save the current screen into memory.
3) How to save the current screen as an image for use as a texture.

For 1 - just press the PtrScrn button on your keyboard while the program is running! (maybe need to use shift too) or use a utility like MWSnap (free) or HypersnapDX ($30). This will grab the screen into the clipboard where you can paste it into a paint package.

For 2 - best bet would be to use the pixel locking technique, read the current display into a memblock and then save it out. Not particularly fast, but possible.

For 3 - you can't save images out without the use of a 3rd party DLL at the moment, I believe there is one on the RGT site.

Cheers,

Rich

you can then save it to a file and have your program load it later.

I'm sure there was a save bitmap command somewhere... found it in the DBC help files. Why isn't this supported in DBPro?

Also there's some sort of set camera to image command, which took ages to get to work properly, but I managed a fairly good demo, cubes flying everywhere textured with real-time camera images, unfortunately I've lost it. I'll try and make it again, and stuff it into 20 lines.
